Title: Air-fuel ratio control device for engine
Inventor: KADOTA YOICHI
IPC: F02D45/00
Filed: 1990-06-18
Abstract: PURPOSE:To produce spare time in the calculation-processing time for high speed rotation region by thinning out the measuring process of intake air flow or intake pipe pressure value or throttle opening, and the calculation process of the quantity of supply fuel, when an engine runs at high speeds. CONSTITUTION:When pulse signals corresponding to the engine speed of an engine 1 come from an engine speed sensor 6, a computer 5-3 in a fuel control device 5 inputs various information from an intake air flow sensor 2, a throttle valve 3 opening or pressure sensor 4, etc. Further, the computer calculates the fuel quantity corresponding to these information to send corresponding signals to an injector 7, and controls the quantity of fuel supplied to the engine 1. Thus, when the engine runs at high speeds, the computer detects the engine speed from the engine speed sensor 6 to thin out the calculation-processing process of intake air flow, and the calculation process of fuel quantity. Thus, since spare time is produced in the calculation-processing processing time for high speed rotation region, this device can be used for high speed rotation region and multicylinder engines.

Title: System and method for half-tone recording
Inventor: YOSHIMURA TOMOKI
IPC: B41J2/36
Filed: 1994-07-13
Abstract: PURPOSE:To decrease the circuit scale and prevent a power source from being overloaded by performing electricity feeding control over a thermal head with the number of electric feeding pulses of an input signal for a 1st gradation and with the width of electric feeding pulses of the input signal for 2nd and succeeding gradations. CONSTITUTION:An electric feeding pulse width selector 6 selects electric feeding pulse width with an indication from a CPU 4. At this time, when the CPU 4 indicates electric feeding for the 1st gradation, the selector 6 selects the output of a 1st-gradation electric feeding pulse width generating means 1b and an electric feeding pulse switch 5 outputs it to an electric feeding pulse generating means 2a first. After electric feeding pulses 3a and 3b are outputted from pulse generating means 2a and 2b, 1st and 2nd electric feeding pulse end signals are counted respectively and when the number N of 1st-gradation pulses which is previously set by the CPU 4 becomes equal to the counted number, the CPU 4 sends an indication to the selector 6 to select a 2nd-and-succeeding-gradation pulse generating means 1a. Consequently, the electric feeding control over the thermal head is performed.

Filed: 1989-06-23
Abstract: PURPOSE:To promote performance at the time of a small amount of flow by selecting a primary flow route at the time of a large amount of fluid flow and at the time of a small amount of flow selecting a secondary flow route of which sectional area in a flow passage is smaller than that of the primary one. CONSTITUTION:A primary flow route A is so formed that at a refrigerant condenser 3 solenoid valves 14, 17 are opened and an solenoid valve 16 is closed and then the refrigerant supplied to the upper room 10a and the lower room 10b through an inflow pipe 13 and a branched pipe 15 flows in each tube 8 and flows into a header 11 at the outlet side and flows out from an exit pipe 19. A secondary flow route B is formed in such a way that by closing the valves 14,17 and opening the valve 16 the refrigerant only supplied to the room 10a through the pipe 13 flows through the upper five tubes 8 and flows into the header 11 and then flows through the lower three tubes and flows in the room 10b and flows out from an exit pipe 18. Thus, as the primary flow route A is selected at a large amount of flow and the secondary flow route B is selected at a small amount of flow, the refrigerant flow amount at the time of a large and small amount of flow can be properly established.

IPC: F02P17/12
Filed: 1983-09-02
Abstract: PURPOSE:To detect misfire by installing two pairs of fail-signal generating circuits of an ignition apparatus having an intermediate tap and setting the trigger voltage lower than the second peak value in the primary voltage wave-form in case of misfire and comparing and discriminating the both. CONSTITUTION:Electric-current control circuits 3a and 3b repete switching alternately on the basis of the signal supplied from a revolution-angle sensor 1, and fail-signal generating circuits 4a and 4b generate the pulses which are synchronized with ignition and has a constant time width. In normal ignition, pulses are generated on two fail-signal lines C and D alternately. When a trouble is generated because of an anomaly, the vibration wave-form having a reverse phase is generated, and when each trigger voltage of the fail-signal generating circuits 4a and 4b is set lower than the second peak voltage in the primary voltage wave-form, pulses are generated at the same time and can be detected by a spark trouble detecting circuit 5. Therefore, the engine can be stopped in case of spark trouble, and therefore, the secondary trouble can be prevented.
