Title: Stabilized power source circuit
Inventor: KANEKO SHINJI
IPC: G05F1/56
Filed: 1982-11-09
Abstract: PURPOSE:To rapidly correct the variation in the output of a stabilized power source by controlling the ON period of a switching transistor and the impedance value of a variable impedance in response to the variation of the output voltage. CONSTITUTION:Detected voltage relative to a current which is flowed through variable impedance transistors 261, 262 is detected at both terminals of resistors 281, 282, the detected voltage is supplied through amplifiers 291, 292 to a composite unit 30, and the output is supplied to a drive pulse generator 18 through a comparator 16. When the output DC voltage of an output terminal 14 tends to decrease from the prescribed constant value due to variations in a load or a ripple, the ON period of a transistor 8 becomes long, the resistance between the collector and the emitter of the transistor 261 simultaneously becomes and the resistance between the collector and the emitter of the transistor 262 become small, thereby preventing the output DC voltage from decreasing.

Title: Control device for engine
Inventor: MIYAJI YOSHIHIKO
IPC: F02P9/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a device in which a normal mode for performing a normal operation when an engine is started and a special mode for performing blank ignition can be selected, heavey carbonization of a spark plug is prevented and a starting time is prevented from being unnecessarily extended. SOLUTION: When a starter switch is turned ON (S21) or when an ultra-slow speed rotation occurs (S22), a special mode is selected (S24) while a mode change-over switch is turned ON, and then a fuel injection prohibiting flag FLGPE is set (FLGPE←1) (S26) until the number of times of spark plug electrical discharging operations reaches a predetermined number of times (S25). At this time, a fuel injection pulse width Ti is set to 0 (Ti←0). Accordingly, when a special mode is selected, the fuel injection is stopped while the number of electrical discharging times of the spark plug reaches the set number of times, and heavey carbonization is prevented by blank ignition at the spark plug. In addition, when the mode changing-over switch is turned OFF and the normal mode is selected, the fuel injection prohibiting flag is cleared (S27).  At this time, the blank ignition is not carried out, a fuel injection is carried out as usual and a starting time is prevented from being extended.

IPC: G06T5/00
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To extract a pseudo half tone area with high accuracy by detecting an isolated picture element from a received binary image so as to exclude a character area. SOLUTION: When an isolated picture element detection section 101 detects a picture element of interest to be at a black level and picture elements adjacent to the picture element of interest to be all at a white level or the level relation of them is reverse, the detection section 101 discriminates the picture element of interest to be a isolated picture element and provides an output of a level '1' to an isolated picture element correction section 102 and an isolated picture element accumulated section 103. The correction section 102 counts number of frequency of each picture element of interest when a picture element at a periodic distance in the main scanning direction and the picture element of interest are equal and provides an output to an isolated picture element accumulation section 104.  A pseudo half tone discrimination section 105 discrimination whether or not the picture element of interest belongs to an error spread area based on outputs of the accumulation sections 103, 104 and provides an output of '1' when the picture element of interest belongs thereto and an output of '0' when not belongs thereto to a main scanning direction correction section 105, which corrects an output of the discrimination section 105 based on a consecutive pixel number in the main scanning direction. A sub scanning direction correction section 107 applies similar processing in the sub scanning direction to the case with the correction section 106 to correct the discrimination result of the discrimination section 105 and to provide an output.
