Title: Controller for continuously variable transmission
Inventor: SATO YOSHIJI
IPC: F16H61/28
Filed: 1989-12-09
Abstract: PURPOSE:To improve the responsiveness of a controller by obtaining primary pressure required for maintaining fixed transmission for fixed input torque to secondary pressure, and adding or subtracting pressure necessary for an oil pressure ratio and a flow rate control system into or from the above primary pressure to determine target primary pressure. CONSTITUTION:A computing section 88 computes necessary primary pressure corresponding to an input torque ratio KT in the normal case and a speed change ratio (i) to secondary pressure established by a setting section 80, and a primary control valve is controlled on the primary pressure computed by the computing section 88 through a target primary pressure computing section 95, a solenoid current setting section 96 and proportional solenoid 61 to maintain each speed change ratio on the above oil pressure ratio. On the other hand, at transient time, a speed change pressure computing section 94 for a flow rate control system computes pressure  Pp required for producing speed change speed de/dt, and the computing section 95 adds or subtracts the pressure  Pp into or from a pressure ratio control system to increase or decrease the target primary pressure, and the primary control valve increases the primary pressure for upshifting and decreases it for downshifting. Thus feed forward controllability can be improved.

Title: Video printer
Inventor: YOKOYAMA SHOJI
IPC: B41J2/00
Filed: 1987-12-17
Abstract: PURPOSE:To prevent the occurrence of sampling error by providing a reference voltage generation part which makes variable a reference voltage of a comparator inputting a video signal of TTL level and a D flipflop which holds data synchronized to a sampling clock to be output from PLL using a horizontal synchronization signal as a reference signal. CONSTITUTION:A reference voltage generation part 101 is composed of a circuit with a switch and a resistor connected in series and a circuit with resistors connected in parallel. The reference voltage of a comparator becomes variable by ON/OFF operation of a switch. The comparator 102 creates a waveform using a video signal of TTL level as an input and an output voltage of the reference voltage generation part 101 as a threshold level. In the case of an input video signal A, an output of the comparator is converted to a waveform of a=b, if an input power of the reference voltage generation part 101 is set to VA. A D flip flop 103 holds an output of the comparator 102 at a rising edge of a sampling clock to be output from PLL 104. The PLL 104 uses an output signal of VCO as a sampling clock.

Title: Dual fluid injection device
Inventor: AKAGAWA HIROKAZU
IPC: F02M25/022
Filed: 1993-11-26
Abstract: PURPOSE:To reduce thermal stress of an engine while reducing NOX by providing an annular groove communicating to a water passage at lifting a needle valve by a certain quantity on the outer circumference of a needle valve opening/closing, and providing a water nozzle hole directed so as to inject water in the annular groove toward the high temperature part in a combustion chamber. CONSTITUTION:An annular groove 9 is formed on the outer circumference of the extreme end part of a needle valve 6, and a water nozzle hole 8 communicating to the annular groove 9 at lifting the needle valve is provided on the extreme end part of a nozzle tip 4. When the lift of the needle valve reaches a certain quantity, the upper edge part of the annular groove 9 crosses a water passage 20, and the annular groove 9 and the water passage 20 are communicated with each other. Because the lower part of the annular groove 9 and the water nozzle hole 8 are already communicated with each other, water in the water passage 20 is injected toward the high temperature part in a combustion chamber from the water nozzle hole 8 through the annular groove 9 for cooling. Hereby, the temperature of the wall part of the combustion chamber is lowered, the thermal load is reduced, and the NOX is reduced like a fuel-water injection engine.
