Title: Cylinder injection internal combustion engine
Inventor: NISHIMURA SEIICHI
IPC: F02B61/04
Filed: 1989-10-17
Abstract: PURPOSE:To prevent generation of a choke of carbon in a valve or the like with a number of part items and a cost up suppressed for obtaining pressure gas by providing constitution such that the pressure gas in an accumulating means, introduced from a combustion chamber at the time of fuel injection, is injected with fuel into the combustion chamber from a nozzle. CONSTITUTION:Constitution is provided such that a nozzle 19 communicates with a pressure gas accumulating chamber 46, and pressure gas in a combustion chamber 16 can be drawn out and introduced to the accumulating chamber 46 with its pressure gas injected with fuel into the combustion chamber 16 from the nozzle 19 at the time of fuel injection. Thus by pressure-compressing the inside of the combustion chamber 16 following lifting a piston, when the pressurized gas is drawn out and utilized as pressure gas mixed with fuel, the necessity is eliminated for a separate exclusive use compressor and/or for utilizing high temperature combustion gas. While, when pressure gas in the combustion 16 is drawn out through the nozzle 19 for injecting fuel in the combustion chamber 16, the necessity for providing a separate nozzle for this drawing out is eliminated.

Title: Signal processing circuit
Inventor: ABE MASATO
IPC: H03H17/00
Filed: 1986-11-13
Abstract: PURPOSE:To obtain a delay signal with small sized constitution by using an adder/subtractor circuit and an amplitude correction circuit. CONSTITUTION:A sampled and binary-coded signal is inputted to a terminal 1 in parallel 8-bit. An adder/subtractor circuit 2 subtracts a prescribed value alphai generated by a constant value generating circuit 4 for a 1/2 period where an instantaneous value of an input signal rises and adds a prescribed value alphai to the input signal at a 1/2 period where the instantaneous value of the input signal is decreased. Then the output of the adder/subtractor circuit 2 is a signal delayed by a time in response to the value alphai with respect to the input signal. The output of the circuit 2 is distorted by overflow or underflow for a time between a peak of a delay signal waveform and a point of time when the input/output signal waveform gives a peak at each 1/2 period. Aa amplitude correction circuit 6 is operated during this period by an output SC2 of a timing signal generating circuit 5 to correct the distortion.

Title: Coater
Inventor: NORO FUMIHIKO
IPC: B05C11/08
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To restrain manufacturing cost by reducing the number of types of solutions to be used and reducing the quantity of the solutions to be used through effective use. SOLUTION: A coater includes a substrate chuck 101 having a flange 110 formed on the peripheral portion thereof so that a semiconductor substrate 104 may be embedded and held in a recess 111 surrounded by the flange 110 without generating any gap, a rotary bar 107 for rotating the substrate chuck 101, and a coating solution 106 to be dropped on the upper surface of the semiconductor substrate 104. As the semiconductor substrate 104 is embedded in the recess 111, the upper surface of the semiconductor substrate 104 is held at the same level as or higher than that of the upper surface of the flange 110. Since the substrate chuck 101 has such a structure that the semiconductor substrate 104 may be embedded and held without having any gap, the coating solution 106 is prevented from entering the back side of the semiconductor substrate 104, and therefore cleaning of the back side is not necessary. Thus, an exhausted solution of the coating solution 106 which was not effectively used is prevented from being mixed with a cleaning solution, and therefore may be reused.

Title: Suspension control device
Inventor: OGAWA KAZUO
IPC: B60G17/018
Filed: 1994-10-07
Abstract: PURPOSE: To keep riding comfort and travel stability compatible with each other at the time of changing a damping force on the basis of a speed ratio of an on-spring speed to a relative speed. CONSTITUTION: An on-spring speed Zd and a relative speed Td are obtained on the basis of a detection signal from a sensor, and a speed ratio Zd/Yd is computed at steps S110 and S120. In order to keep a damping force corresponding to the ratio Zd/Yd, a sky hook damping factor is reduced to lower the damping force at a step S130, if a travel speed V is low. Also, a driving frequency for a stepping motor as a drive source for a damping force change is reduced at the time of changing the damping force at a step S180, if the speed V is low.  As a result, the variation extent of the damping force can be restrained, and the variable acceleration thereof can be reduced at a low- speed travel, thereby alleviating a shock or a feeling of physical disorder associated with the delay of control for changing the damping force, due to an equipment response delay such as a delay in detecting the relative speed.
