IPC: F02B23/10
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To generate an air-fuel mixture near an ignition plug by a fuel spray injected by a first fuel injection pulse signal and to improve the combustibility by dividing the fuel injection pulse signal in a compression stroke into a plurality of pieces, and setting the first fuel injection pulse width longer than a second and later fuel injection pulse widths.

On the other hand, the fuel injection period is set to the latter part of compression stroke in stratified combustion range. In the stratified combustion range, the pulse signal in the same cycle is divided into a plurality of signals, for example, three, a first injection pulse width is set longer than a second injection pulse width, and the second injection pulse width is set longer than a third injection pulse width. Thus, an air-fuel mixture satisfying the combustible air-fuel mixture concentration can be generated near an ignition plug 7 to improve the combustibility.

Title: Signal processor for video camera
Inventor: TANAKA SEIJI
IPC: H04N9/73
Filed: 1985-10-30
Abstract: PURPOSE:To prevent malfunction of white balance under low illumination by detecting the low illumination and using a detection signal to allow a control signal setting the white balance not to fed to a white balance circuit. CONSTITUTION:When an automatic gain control (AGC) voltage 17 is further decreased than a threshold level under low illumination, a transistor (TR) Q1 is turned on and a TR Q2 is turned off. Thus, 0V is applied to a gate of a FET Q3, which is turned off. Thus, a white set signal (a) is not fed to the white balance circuit. Conversely, when the AGC control voltage is higher than a threshold level, the TR Q2 is turned on and a high voltage is fed to a gate of the FET Q3. Thus, the FET Q3 is turned on and the white set signal (a) is fed to the white balance circuit.
