An in-vehicle power transmission apparatus is equipped with a motor-generator working as an engine to drive a vehicle and a power split device made up of a plurality of power split rotors. A first one of the rotors is coupled to a driven wheel of the vehicle, while a second one of the rotors is coupled to an accessory such as an air compressor of an air conditioner. The speed of the second rotor is controllable independently of that of the driven wheel. This eases restrictions on the supply of power produced by the generator-motor to the accessory. Alternatively, the rotors are so linked that when the speed of the first rotor is not zero (0), the speed of the second rotor has one of zero (0) and a value other than zero (0), thus ensuring the stability in supplying the power to drive the vehicle to the accessory.

A blood constituent concentration detector includes: a detection portion having an optical window for measuring a blood constituent concentration of a part of a living body in an optical manner when the part of the living body is pressed on the detection portion; a load determination element for determining whether a load to the detection portion is equal to or larger than a first threshold, and smaller than a second threshold, wherein the second threshold is larger than the first threshold; and a measurement element for measuring the blood constituent concentration when the load determination element determines that the load to the detection portion is equal to or larger than the first threshold, and smaller than the second threshold.

A swing member is supported by a swing support member like a universal joint of a Hook's type such that it can swing in a state where it is prevented from rotating around a center line. In this manner, even if a shaft rotates at high speed, the swing member is surely prevented from rotating around the shaft. Therefore, it is possible to prevent a piston from excessively vibrating, hence to prevent large noises from being made, and to improve reliability and durability of a compressor when the compressor is operated at high speed.

Wobble type fluid pump having swing support mechanism

A variable displacement compressor includes a linking groove, which forms a hinge for connecting an arm and an inclining member. The groove is generally U-shaped (open). A link pin is fitted in the groove such that the link pin can pivot or slide within the groove. As a result, installation of a movable parts assembly, which is done by inserting the link pin into the groove, is easier. A controlled pressure chamber improves the response of the compressor to controls.

Variable displacement compressor

In a refrigerant cycle system, refrigerant compressed in a first compressor is cooled and condensed in a radiator, and refrigerant from the radiator branches into main-flow refrigerant and supplementary-flow refrigerant. The main-flow refrigerant is decompressed in an expansion unit while expansion energy of the main-flow refrigerant is converted to mechanical energy. Thus, the enthalpy of the main-flow refrigerant is reduced along an isentropic curve. Therefore, even when the pressure within the evaporator increases, refrigerating effect is prevented from being greatly reduced in the refrigerant cycle system. Further, refrigerant flowing into the radiator is compressed using the converted mechanical energy. Thus, coefficient of performance of the refrigerant cycle system is improved.

Refrigerant cycle system with expansion energy recovery

A catalytic combustion heater having, in a fuel gas flow passage in which an inflammable gas- and combustion support gas-containing fuel gas flows, tubes in which an object fluid to be heater flows, and an oxidation catalyst provided on outer surfaces of the tubes and contacting the fuel gas to generate an oxidation reaction, comprising a catalyst-carrying heat exchanger adapted to heat the object fluid with the oxidation reaction heat of the fuel gas, a detecting member adapted to detect the temperature of a combustion exhaust gas in the fuel gas flow passage to check whether the temperature is at the level of a dew point thereof or not, and a control unit adapted to control at least one of a feed rate of the combustion support gas, which is supplied to the fuel gas flow passage, and a feed rate of the inflammable gas.

A heating apparatus for a vehicle includes a pump for circulating cooling water in a cooling water circuit, a heating heat exchanger for heating air blown into a passenger compartment of the vehicle using cooling water as a heating source, and a throttle valve disposed at a discharge side of the pump. In the heating apparatus, when the temperature of cooling water is low and heating capacity for heating the passenger compartment is insufficient, an opening degree of the throttle valve is reduced by a control unit. Therefore, heat is generated from the throttle valve and the pump so that the temperature of cooling water is increased. Thus, heating capacity of the heating apparatus can be improved without using a manual operation.

Heating apparatus for vehicle

A compressor of scroll type or the like, in which, in order to change the discharge capacity automatically in accordance with the rpm (rotational speed) of a shaft (,) by simple means, the centrifugal force exerted on a movable scroll (,) orbiting with the rotation of the shaft (,) is used as a vibratory force to forcibly vibrate a spool (,) constituting a valve body supported on an elastic member (,), thereby opening and closing bypass holes (,) for establishing communication between a working chamber (V) and a suction chamber (,).

Variable capacity-type scroll compressor

A viscous liquid heater is composed of a housing having a heat chamber filled with viscous liquid, a rotor disposed in the heat chamber and a rotary plate movable to change volume of the heat chamber. The rotor rotates in the heat chamber and shears the viscous liquid to generate heat. The temperature of the heat chamber is controlled by changing volume of the heat chamber.

Viscous liquid heater

A hybrid vehicle in which, by using a continuously variable transmission inserted between output shafts of a heat engine such as an internal combustion engine and an electric motor as a torque distributor, the torque acting upon the driving wheels is distributed to the two and the distribution ratio between the engine and motor is changed, and control is performed so that the speed and/or torque of the heat engine becomes a predetermined constant value and the exhaust emission and fuel consumption are enhanced.

Hybrid vehicle

A hybrid vehicle comprises a motor driving the vehicle's wheels, multiple batteries supplying electric power to the motor, and a generator driven by an internal combustion engine to generate electric power for charging the batteries. Battery sensors detect terminal voltages of the batteries. An ECU controls a DC/DC converter to distribute electric power to independently charge the batteries through charge lines in accordance with the shortage of charge in respective batteries when excess electrical power is available from the generator even after a required amount of electrical power from the generator is used to rotate wheels.

Battery charge control system for a hybrid vehicle driven by an electric

An alternator provides its output current waveform directly or via a current probe to a low pass filter and a high pass filter. The resulting waveform is provided to a half-wave rectifier and a comparator to obtain a rectangular waveform. The arithmetic circuit determines the number of clock pulses between rectangular waves to obtain the rotation speed of the alternator. The torque due to auxiliary devices is computed based on the ratio of the rotation speed of a crankshaft to the rotation speed of the alternator.

Device and method for accurately detecting torque of auxiliary device

A series hybrid vehicle includes a generator to be driven by an engine, a battery to be charged by the output power of the generator, and a motor for driving the vehicle using the output power sent from the generator and the output power sent from the battery. In an engine control system for the series hybrid vehicle, the values of power demanded by the vehicle when the vehicle is running (i.e., power demand values) are derived based on various engine operation indicative sensor signals, and a running state of the vehicle is estimated based on a frequency distribution of the power demand and a mean value of such power demand values. The system selects one of prestored control patterns depending on the estimated vehicle running state and controls the engine based on the selected control pattern so as to further control the output power of the generator. The system is also applicable to a parallel hybrid vehicle.
