A fuel heating device comprises a heater housing () including a bottom wall (), an upper inlet opening () provided in an upper part of the heater housing and an outlet opening () provided in a lower part of the heater housing diametrically opposite to the inlet opening, and a heater member () including a heat emitting portion () received in a middle part of a heating chamber () defined by the heater housing. As the inlet opening is provided in an upper part of the fuel housing, bubbles that may be created by the vaporization of the fuel heated by the heater member is allowed to rise upward and then escape out of the inlet opening. The bubbles that have returned to the fuel supply passage () are cooled by fresh fuel, and condense to liquid state once again. Therefore, the heater housing and fuel supply passage are kept free from the presence of fuel vapor, and the fuel therein can be pressurized by a fuel pump to a proper level at all times. Also, the presence of fuel vapor in the heating chamber is controlled so that the heater member is prevented from being exposed to the vapor phase of the fuel.

In a printer, a sheet discharge port for discharging a sheet therefrom is provided on the upper surface of an exterior case, and a recess portion for preventing invasion of a foreign material into the sheet discharge port is formed in the neighborhood of the sheet discharge port. The recess portion passes by the sheet discharge port, and at least one of the ends thereof is opened to the side surface of the exterior case. The side surface of the exterior case to which the open end of the recess portion is adjacent forms a foreign material discharging passage along which a foreign material discharged from the open end of the recess portion falls down without invading the printer.

An ink switching cam () is rotated interlockingly with forward/reverse rotation of a head driving motor at all times to swing a cassette support member (). Accordingly, ink belts can be switched with a simple construction without using a solenoid or the like. By setting a movable area of the ink switching cam () to be within one rotation, the operations of a print head () and the ink switching cam () which are interlocked with the forward/reverse rotation of the head driving motor can be simply associated with each other.

A needle guide () is composed of a first guide wall () and a second guide wall () arranged at a distance x from each other. Each of these guide walls is formed with through holes through which needles penetrate and which extends parallel to the longitudinal direction of a needle bunch, the through holes of the first guide wall and the second guide wall for one needle is shifted from each other in the convergence direction of the needles with a shift amount &#x3b4;n determined by the distance x and a convergence angle &#x3b8;n of the needle.

An engine speed calculating apparatus capable of calculating an engine speed without being affected by pulsating revolutions in a low engine speed range. A time required for a crankshaft of an engine to revolve through a predetermined angle is measured upon each completion of revolution through the predetermined angle, and an engine speed is calculated on the basis of measured result data of the time required for revolution through the predetermined angle. When the preceding calculated engine speed is determined to be lower than a predetermined engine speed, an engine speed is calculated on the basis of a time required for the crankshaft to revolve through an angle larger than the predetermined angle.

A stroke identifying unit, for an electronic fuel injection control system of an engine, can identify cylinder strokes without detection of the rotation of the engine's camshaft. The stroke identifying unit includes a crank pulse generator for detecting a phase of a crankshaft of the engine. In a four cylinder engine, an intake pressure sensor detects the combined intake pressures in the second to fourth intake pipes, communicating with the second to fourth cylinders. A fuel injection control unit identifies strokes of the first to fourth cylinders on the basis of a relationship between the detected phase of the crankshaft and the detected intake pressures.

To provide an engine speed calculation apparatus which can facilitate calculation processing of the engine speed without being influenced by pulsation rotation in a low speed region of an engine. In a low speed region of an engine, a predetermined value is divided by a time required for rotation over an angle equal to a plurality of times of a predetermined angle to calculate the engine speed, but in a high speed region of the engine in which pulsation occurs less likely, the predetermined value is divided by the value equal to the plurality of times of the time required for rotation over the predetermined angle to calculate the engine speed.

Engine speed calculation apparatus

The present invention provides a control apparatus for controlling an internal combustion engine that enables preferable acceleration in response to the running status of the internal combustion engine. When a computer which computes the fuel supply of the internal combustion engine at each engine cycle according to engine parameters detects a change in the throttle opening level of the internal combustion engine from a low opening level which is lower than a predetermined opening level to a non-low opening level which is higher than the predetermined level and when the computer detects that a variation &Dgr;&thgr;,in the opening level of a throttle is equal to or greater than a predetermined value, the computer generates different increment correction values and corrects fuel supply according to the increment correction values.

Control apparatus for controlling internal combustion engine

A box of a device is comprised of a lid and a body for housing an electronic unit. An operating section of the device is arranged on the portion of the body surface covered by the lid. The covered portion of the body is formed with a hole for leading a cable from the inside to the outside of the body. A groove for accommodating a cable is formed continuous with the hole and a depression for accommodating a connector is formed adjacently to the groove in the surface of the upper cover. Further, another groove for guiding the cable out of the side of the body is formed in the surface of the body. When the portable electronic device is not in use, the connector and the cable are accommodated in the depression and the groove, respectively. The connector and the cable can be easily taken out of the depression and the groove, respectively, when the portable electronic device is used. At this time, the cable is led out of the guide groove. Therefore, no unreasonable force is exerted on the cable when the device is used.

An ignition timing control device for an internal combustion engine is capable of preventing shock of an engine upon rapid acceleration by suitably controlling the ignition timing of the engine. When the width of the opening of a throttle valve is kept within a specific width for a first specific time or more in a state where the opening of the throttle valve is smaller than a specific low opening and immediately after, the opening of the throttle valve is increased from the specific low opening to more than a specific high opening for a second specific time or less, it is decided that the internal combustion engine is in a rapid acceleration state. Ignition timing of the engine is therefore retarded.

Ignition timing control device for internal combustion engine

Optimum control is performed in one cylinder of an internal combustion engine. By determining a desirable control operation stage for each cylinder in advance on the basis of engine parameters. Control operation is executed at the timing where the operation stage for each cylinder reaches the determined control operation stage.

Internal combustion engine controller

An ignition timing control method and apparatus for an internal combustion engine mounted on a motor vehicle can prevent the occurrence of the knocking in the internal combustion engine. When the engine is running within a specific speed range and the transmission gear ratio is high, the control device determines that the engine is running under a condition where knocking is likely to occur. Accordingly retarding of the ignition timing in the internal combustion engine is accomplished in order to prevent knocking.
