Title: Fuel injection control device for engine
Inventor: ISHIDA KATSUMI
IPC: F02D41/10
Filed: 1989-05-15
Abstract: PURPOSE:To responsively raise the rotating speed of an engine, when an acceleration control signal is generated during asynchronous injection, in succession to the present asynchronous injection, by carrying out asynchronous injection corresponding to the new acceleration control signal. CONSTITUTION:Having been input signals of a water-temperature sensor 14, a crank-angle sensor 18, and an intake-pressure sensor 20, a fuel injection control device 100 calculates a necessary fuel injection quantity, and drives a fuel injection valve 8 to carry out synchronous injection, and when it is detected that a throttle valve 6 is widely opened through the signal of a throttle sensor 16, an acceleration control signal or asynchronous injection signal is output to the fuel injection valve 8 to carry out asynchronous injection. If it is judged further a new acceleration control signal has been generated during the asynchronous injection, in succession to the present asynchronous injection, asynchronous injection corresponding to the new acceleration control signal is carried out. Thus, acceleration feeling can be enhanced.

Title: Capacitance type level sensor
Inventor: KOBAYASHI TAMOTSU
IPC: G01F23/26
Filed: 1995-04-21
Abstract: PURPOSE: To enable detection of the surface of a storage liquid and an interface between this storage liquid and water with certainty by installing a rectifying-smoothing circuit which converts the output of a buffer circuit into that of a sensor after rectifying and smoothing it, and a high frequency power source. CONSTITUTION: When a detecting element 1 is in a water phase, a dielectric constant of water is very high as 80, and since an interval between electrode plates of this detecting part 1 is approximate to a state of being shorted, voltage in a bridge output terminal 5 is the same phase as the voltage of a high frequency power source 4, therefore its amplitude also becomes electric potential approximate to this phase. Accordingly, a large rectifying output appears in an output terminal 8, and in the case where a synchronous commutation is carried out in a rectifying-smoothing circuit 7, polarity of output voltage in this output terminal 8 becomes negative, by way of example, if voltage from the high frequency power source 4 is negative.  Next, when the detecting element 1 is in a gas phase, capacity in this detecting element 1 decreases, and thereby electric potential in the bridge output end 5 comes nearer to that of a high frequency power source 3. In addition, when the circuit 7 is used, whether the detecting element 1 is in the water phase or the gas phase can be judged by a polarity judgement in output potential, so that it is no need to take a dynamic range in a buffer circuit 6 so wide.

Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To ensure good handling performance by supplying air into an optical chamber to keep a positive pressure therein thereby substantially preventing adhesion of toner or paper powder to the outside of an optical scanning unit. SOLUTION: An optical scanning unit 2 is provided with a fan 7 for supplying air into an optical chamber 6 and the air taken into the optical scanning unit 2 is used as cooling air for the mirror motor part, or the like, in the optical scanning unit 2. It is discharged from an exhaustion vent 4b to the outside of the optical scanning unit 2 and fed to the gap between the outer side face of the unit 2 and the inner surface of the optical chamber 6. When the cooling air is exhausted to the optical chamber 6, pressure in the chamber 6 becomes positive and the cooling air flows to the outside. A cover 10 is provided above the optical chamber 6. The air flows most from a laser light passing part 4a provided at a part of a barrier wall member 4 to the print chamber 5 side.  Consequently, toner or paper powder scattering in the vicinity of a print unit 1 is pushed back to the print chamber 5 side by the air flowing out from the laser light passing part 4a.
