Title: Operating method of speed change gears
Inventor: ISHIDA HISAO
IPC: F16H61/08
Filed: 1982-10-07
Abstract: PURPOSE:To enable a shift actuator to be smoothly driven, by operating a selecting actuator in order to hold speed change gears in its presently selected position of its speed change step while the shift actuator is operated to be shifted from the presently set speed change step to the neutral position during speed change operation. CONSTITUTION:While a shift actuator 20 is shifted to the neutral position, a selecting actuator 10 is operated in order to hold speed change gears at a selected position of 1-2 speed shift being the presently set speed change step, because a valve V5 is selected to the side of a pump P.

Abstract: PURPOSE:To correct a controlled variable with high accuracy even when the change in intake air temperature accompanying the change in intake pipe pressure is unable to be detected by means of an intake-air temperature sensor by correcting the correcting value of an intake air temperature in accordance with the error in detection of the intake air temperature. CONSTITUTION:In an electronic control circuit 40, an intake pipe pressure at the present point of time detected by an intake-air pressure sensor 22 is moderated by the past average value to calculate the average value of the intake pipe pressure.

IPC: G02B26/10
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To facilitate adjustment for matching a scanning line with a preset sub-scanning writing position on a photoreceptor. SOLUTION: A synchronization sensor 12 detects a laser beam before the scanning line enters a writing area, and outputs a synchronizing signal. On the other hand, a photoreflector 14 detects a mark provided on the upper surface of a polygonal mirror, and outputs one phase signal by each rotation. When a laser diode(LD) control circuit 20 detects the synchronizing signal first after the detection of the phase signal, the light emission of LD is continued for a previously set term or the light emission of LD is performed for the preset time a specified time later. Consequently, the scanning line by the specified mirror surface of the polygonal mirror is adjusted and matched with the sub- scanning writing position by detecting the position in the sub-scanning direction during the preset term and time.
