Abstract: A sensor unit includes a unit main body mounted on a throttle device, and a pressure sensor chamber that is provided at the unit main body and that accommodates an intake pressure sensor to detect an intake pressure through an intake pipe. The pressure sensor chamber is divided by a partition into a pressure receiving area to receive a pressure in the intake pipe and a pressure detecting area to detect the pressure by the intake pressure sensor, such that the pressure receiving area communicates with the pressure detecting area through a communication portion. A foreign substance is prevented from flowing into the intake pressure sensor when guiding air in the intake pipe to the intake pressure sensor, thereby improving detection accuracy by the intake pressure sensor.

Abstract: A cathode substrate according to the present invention comprises a cathode electrode layer (12), insulator layer (14) and gate electrode layer (15) formed sequentially on a substrate to be processed (11). The insulator layer includes a hole (14a) formed therethrough. A gate aperture (16) is formed through the gate electrode layer. An emitter (E) is then provided at the bottom of the hole (14a). In this case, the gate aperture comprises a plurality of openings (16a), the total area of which is smaller than the area of top opening of the hole in the insulator layer. The openings are arranged densely at a position opposite to the emitter and just above the hole of the insulator layer.

Abstract: A temperature sensor is disposed at a position upstream of a throttle shaft in the flow channel so as not to contact the throttle valve. An inlet of a guiding path in the flow channel is arranged downstream of a first half part of the throttle valve that is revolved in an upstream direction when the throttle valve is revolved in an opening direction, the guiding path guiding a pressure to the pressure sensor. A first screw which attaches the sensor unit to the throttle body is disposed at a position upstream of a half part. A second screw is disposed at a position downstream of the other half part. A detected temperature of intake air is corrected to a temperature of intake air detected near an air cleaner.

Abstract: The engine startup performance and stability of the power supply voltage in activation of loads is concurrently ensured in a battery-less power supply apparatus. The power generated in an AC generator 11 is supplied to a power supply line L via a regulator 12. The power supply line L is parallel-connected to a fuel injection system (FI load) 13 and first capacitor 14, and further parallel-connected to DC loads 15 and second capacitor 16 via a switch 17. After the first capacitor 14 is charged, the second capacitor 16 is charged by ON/OFF of the switch 17. When a plurality of loads contained in the DC loads 15 is simultaneously activated, the second capacitor 16 additionally supplies the power to each of the DC loads 15 to prevent the voltage of the power supply line L from decreasing.

Abstract: In a solenoid driving device of the type in which energy stored in a capacitor is used for re-driving of the solenoid, the generation of heat in a current back-flow preventing circuit preventing the back-flow of current to a power supply terminal is suppressed, and the generation of heat in a rectifying element through which the current that flows to the capacitor passes is suppressed. Electric power accumulated in the solenoid when the driving of the solenoid is stopped is temporarily stored in the capacitor, and a high voltage that is generated by the charging utilizing the peak voltage of the capacitor is utilized as the power supply for a discharge control circuit that controls the discharge of the capacitor. The current back-flow preventing circuit is constructed from a switching element such as an FET so that the generation of heat in this circuit is suppressed.
