Title: Bicmos logic gate circuit
Inventor: OKAMURA HITOSHI
IPC: H03K19/0944
Filed: 1995-03-10
Abstract: PURPOSE: To lower the cost by taking out the voltage across a load element interposed between one drain of an MOS transisotor(TR) couple and a power source, as the output voltage of a logic signal. CONSTITUTION: An inverter circuit is equipped with 1st and 2nd NMOS TRs 6 and 7 which have their sources connected in common and their gates connected to input terminals 14 and 15 to constitute a differential TR couple. Then one terminal is connected to GND1 and the other terminal is connected to resistance elements 3 and 4 connected to the drains of the TRs 6 and 7. When complementary logic signals are inputted to the gates of the TRs 6 and 7, the TR 6 to which the relatively high level is inputted turns on and the TR 7 to which the relatively low level is inputted turns off. The gate width of the TRs 6 and 7 is so set as to obtain a current difference which is large enough to turn on and off them with the input signal amplitude. When the TR 6 turns on, the drain current becomes equal to the current value of a constant current source.  Then the voltages of the resistance elements 3 and 4 are led out and usable as the output voltages of the logic signals.

Title: Shaping sheet
Inventor: HINISHI EIJI
IPC: B32B33/00
Filed: 1989-03-30
Abstract: PURPOSE:To obtain a shaping sheet wherein the parts different in luster are formed on the surface of a decorative sheet made of thermosetting resin and a foreign matter is prevented from being stuck by static electricity and also a fine unevenness can be excellently reproduced by providing a barrier coat layer, a lusterless pattern layer and a mold release layer in this order on paper having the smooth double sides. CONSTITUTION:Paper 1 becoming the base material sheet of a shaping sheet is good in smoothness of the double sides and uniform in formation in order to make the difference of luster sharp when the patterns different in luster are formed on a decorative sheet. A barrier coat layer 2 prevents infiltration of thermosetting resin into the base material sheet 1 which results from thermocompression at a time for molding the decorative sheet. Smoothness and formation of the base material sheet 1 are compensated thereby and furthermore luster is enhanced and a smooth face is formed. The lusterless pattern layers 3 partially extinguish luster in contrast to the barrier coat layer 2. A mold release layer 4 is formed by applying a mold release agent such as silicone resin and wax. Thereby even when the shaping sheet is allowed to stand, a foreign matter is prevented from being stuck and a fine unevenness can be excellently reproduced.

Title: Ignition device for engine
Inventor: YOKOTA KAZUYA
IPC: F02B31/00
Filed: 1990-03-27
Abstract: PURPOSE:To contrive the reduction in the power consumption for ignition and the enhancement in combustibility by providing a means for producing intake swirls in a specific operation range, and also by restricting the execution of plural ignition in the operation range where intake swirls are produced. CONSTITUTION:In a low load condition of an engine 1, a main port 11a is closed by a swirl valve 19 through a controller 20, and intake air enters a combustion chamber 12 only through a swirl port 11b to form swirls, consequently the flow velocity of ignited mixture can be increased for stabilizing combustion, and only one time of ignition by means of ignition plug 7 is sufficient. In the range where the load of the engine is increased so that the swirl valve 19 is opened to increase the charging rate of intake air, swirls already disappear; while in this region, it is necessary to attach importance to combustibility rather than fuel consumption, and to carry out multiple ignition. Thus, while restraining both the reduction in the voltage of a battery attributable to plural ignition and the increase in the load of an alternator, combustibility can be improved.

Title: Liquid pressure pump with variable capacity
Inventor: NUNOKAWA MICHIO
IPC: F04B49/08
Filed: 1982-05-12
Abstract: PURPOSE:To enhance response for returning to the max. rate of flow by releasing the fluid in the working chamber of a control plunger directly to the tank from a by-pass of by-pass valve and thereby providing momentary return of a variable control element to the max. inclination angle from its neutral position. CONSTITUTION:When the discharge pressure of a pump becomes below a certain specified pressure, a spool 42 moves to the left to release a control passage 5 to the tank 48 through a drain 47. Accordingly the action surface of a check valve element 81 becomes free from control pressure, and no control pressure will now be applied to the back surface 61b of the valve element 61. To action surface 61a, on the other hand, the pressure of fluid pushed back from the working chamber 33 of control plunger 3 is applied, and thus the valve element 61 moves to the left to open the by-pass 7 of by-pass valve 6. Thereby the fluid in the working chamber 33 is released to the tank 70 from the by-pass 7. Accordingly the variable control element 2 shifts momentarily from its neutral position to the max. inclination angle position, and as a result the amount of pump discharge can be returned instantaneously from the minimum rate of flow to the maximum.
