A switch device includes a panel housing a knob, the panel having a wall face around the knob. In at least one of outside faces of the knob, the outside faces opposing the wall face and another member adjacent to the knob, the outside face has a base part formed on an upper side thereof and a recess part formed in a lower side thereof. The recess part extends to a lower end of the outside face. The base part has an obliquely downwardly inclined parts formed on a lower edge part thereof. Accordingly, the device can ensure stable operation of the knob by discharging, from a gap between the panel and the knob, liquid that has entered the gap.

Switch device

In a switch device, a switch part is turned ON/OFF by operation of an operating knob housed in a recessed part of a panel so that a movable terminal and a fixed terminal are in contact or are separated. An outside face, opposing an inner peripheral face of the recessed part of the panel, of the operating knob is an inclined face that is inclined inward of the operating knob in going downward. A gap that widens in going downward is formed between the outside face of the operating knob and the inner peripheral face of the recessed part of the panel. Accordingly, the device can ensure stable operation of the operating knob by discharging, from the gap between the panel and the operating knob, liquid that has entered the gap, and that can improve the appearance.

In a hose having a bent portion, a poor appearance part is prevented from being created in an inner round portion of the bent portion. A bent pipe has a bent portion located in an intermediate part in a longitudinal direction in which a cross section in a radial direction of a round of the bent portion is formed in a flat shape, and non-bent portions being continuous with the bent portion. The flat shape of the bent portion is a vertically long flat shape. With this configuration, when an unvulcanized hose is put on a mandrel and vulcanized, an inner round portion of the unvulcanized hose comes into tight contact with a bent portion of the mandrel and is not separated from the bent portion, so that the poor appearance part is hardly created in an inner round portion of the bent portion.

Bent pipe and manufacturing method thereof

A vehicle running management system under renewable energy includes an electrically driven vehicle having a battery ECU. The battery ECU manages a remaining amount of renewable energy in a vehicle-mounted electric storage device as it increases and decreases when renewable energy is charged into the vehicle-mounted electric storage device and renewable energy is discharged from the vehicle-mounted electric storage device.

Vehicle running management system under renewable energy

A vehicle-mounted electric storage device of an electrically driven vehicle is charged with a necessary amount of energy, which corresponds to an amount of energy consumption in a next-time running of the electrically driven vehicle, such that a shortage of renewable energy at a charging site is compensated for by charging the electrically driven vehicle with system energy.

Charging system for minimizing system energy

An energy power depositing/charging management system and method is provided. When energy is deposited in an energy storage station from an onboard power storage device of a vehicle, a vehicle energy management unit manages reductions in the remaining stored energy level of energy in the onboard power storage device. The vehicle energy management unit and a storage station energy management unit manage increases in the energy remaining amount of deposited energy in the energy storage station, thereby allowing for charging up to the remaining amount of deposited energy of energy identified with an ID for the vehicle in the energy storage station.

Renewable energy power depositing/charging management system

A redundant communication system includes a first control device which calculates a control command value of an electric power device, and outputs first and second command signals; a second control device which controls the electric power device on the basis of one of the first and second control command values; and primary and secondary communication lines for respectively transmitting the first and second command signals to the second control device. The second control device comprises: a primary communication line abnormality determining unit which determines that the primary communication line is abnormal when a non-reception state or an abnormality state of the first command signal continues during a predetermined period; and a control command value switching unit which selects one of the first and second control command values in a switching manner and switches the selection from the first to the second control command value within the predetermined period.

Redundant communication system

A control apparatus for a gas sensor with a built-in heater is provided which can prevent damage to, deterioration of, and reduction in accuracy of detection of, a gas sensor. When an ignition switch is turned ON, supply of electricity to a heaterstarts, and when the temperature in the vicinity of a gas sensor(gas temperature of gas detection chamber) Ts becomes greater than a predetermined temperature #Ti at start, or when a predetermined electricity supply time after start of supply of electricity to the heaterhas elapsed, the gas sensoris started. The flow of off-gas is started simultaneously with starting of the gas sensor, or after starting. When the ignition switch is turned OFF, the flow of off gas is stopped, and the supply of electric power to the gas sensoris stopped. In a state where a temperature difference &#x394;T between the gas temperature Ts inside the gas detection chamber, and an upstream gas temperature Tg is maintained within a predetermined range, the supply of electricity to the heateris stopped after a predetermined time has elapsed after operation of the gas sensoris stopped.

The information distributing server transmits at every given time a request-to-send for vehicle information to the vehicles as well as a request-to-send for station information to the stations. The information distributing server then creates a fuel supply station information associating for each vehicle based on the vehicle information received from the vehicle and the station information received from the stations, and distributes it to the vehicle. When the vehicle receives the fuel supply station information from the information distributing server, it is displayed on the car navigation screen for notifying the driver.
