Title: Engine controller
Inventor: HORI TOSHIO
IPC: F02M25/08
Filed: 1994-05-31
Abstract: PURPOSE:To enable the fuel amount required by an engine to be supplied also when a large quantity of evaporated fuel is generated in a fuel passage, by guiding the evaporated fuel in the fuel passage outside the fuel passage. CONSTITUTION:Fuel is sucked from a fuel tank 30 by a fuel pump 31, pressurized, governed through a fuel pressure regulator 32 to the specific pressure, and supplied to fuel injection valves 34. A fuel passage is provided with a solenoid valve 36 to be operated by being interlocked with an ignition switch 35 of an engine, and it is closed when the ignition switch 35 is turned on and it is opened when the switch is turned off. Since the valve 36 is positioned in the uppermost part of the fuel passage 37, evaporated fuel is collected under the valve 36. Since fuel is pressurized during the operation of the engine, s fuel vapor is hard to be generated. Since the valve 36 is closed, fuel is not leaked outside the passage. When the engine is stopped, the valve 36 is opened, and pressure of fuel in the passage 37 becomes atmospheric pressure, and generated vapor fuel is guided to the outside through the valve 36.

Abstract: PURPOSE:To set a zero position to a certain position most suitable for each disc and return an optical head to the zero position with high precision by setting variably an extent of return in conformity with disc-side condition preliminarily. CONSTITUTION:A photosensor 6 reads several measures beyond a point C of a measure 5C corresponding to the zero position. A signal corresponding to the read measures is given to a position servo circuit 37 through an amplifier 21. Consequently, a reverse driving command corresponding to said read measures is applied to a power amplifier 20. Then, a voice coil motor VCM4 is operated in the reverse direction. Meanwhile, a current value signal obtained by the current detecting resistance of the power amplifier 20 is integrated and is given as the second actual speed signal to the position servo circuit 37. Thus, the device is so controlled that large reverse power is given to the VCM4 when the moving speed of an optical head 2 is high. As the result, the optical head 2 approaches the zero position while oscillating forward and backward around the zero position I.
