Title: Automatic choke device for carburetor
Inventor: ONO FUMIO
IPC: F02M1/08
Filed: 1990-02-27
Abstract: PURPOSE:To get rid of any restriction from the standpoint of setting a carburetor to an engine by setting up a solenoid on-off valve in a passage connecting a pneumatic source to an actuator driving a choke valve, and opening or closing this solenoid on-off valve on the basis of engine speed by a signal out of a flywheel magnet. CONSTITUTION:Whether an engine 31 is in a starting state or overspeed state is discriminated on the basis of rotational frequency of the engine 31 by a signal out of a primary coil of a flywheel magnet 41, and thereby opening of a choke valve 29 is adjusted. For example, when ambient temperature at time of the engine 31 starting is higher, the engine 31 starts at once while the choke valve 29 comes to a state of being fully closed by an actuator 17 operating after receiving pressurization from an air compressor 1, and it is reached to idling speed. Since a solenoid on-off valve 14 is closed when the engine is reached to the idling speed, an unnecessary rich mixture is not fed to the engine, thus smooth starting of the engine 31 conformed to the ambient temperature is secured. As there is no thermostat valve in use, a setup of a carburetor 34 to the engine 31 becomes unrestricted.

IPC: H03M1/36
Filed: 1992-03-04
Abstract: PURPOSE:To obtain the A/D converter with high speed and high accuracy performance operated at a low power supply voltage by providing a full scale voltage adjustment means to a sub A/D converter of 2nd and succeeding blocks in a pipeline type A/D converter. CONSTITUTION:A 1st block 1 generates a difference signal between an input signal and an analog recovery signal in 2-bit quantization, that is, a residual signal. When a gain of an amplifier 1-3 amplifying the residual signal is insufficient, the residual signal does not reach a substantial fill scale but becomes a small full scale. When an error is in existence, a missing bit takes place in the quantization of a 2nd stage A/D converter 2-1 and a conversion error is increased. A full scale adjustment device 3 adjusting a 2nd stage full scale voltage is provided to prevent bit missing from being caused. Thus, the 2nd stage full scale is in matching with a small full scale to prevent an error in bit missing. As a result, the A/D converter with high speed and high accuracy performance operated at a low power supply voltage is obtained.
