Title: Combustion device (engine) having pistons symmetrically housed in the same cylinder
Inventor: AKISAWA NOBUO
IPC: F01B7/14
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To enhance combustion efficiency and reduce the size of an engine in comparison with a conventional 2/4 cycle engine by symmetrically housing a pair of pistons in the same cylinder, and providing a mechanism for operating the pair of pistons simultaneously by one combustion. SOLUTION: In a single cylinder, a pair of pistons 1, 1' are symmetrically housed and they are operated simultaneously by one combustion. In a compression stroke, the pair of pistons 1, 1' are moved toward the center, thereby achieving a compression ratio higher than the case of only one piston. In a combustion stroke, fuel of high concentration is ignited, thus increasing a combustion ratio. The pair of pistons 1, 1' are pushed in directions opposite to each other by explosive force, so that rotating force is generated in crankshafts A, B. Consequently, the engine is excellent in combustion efficiency and can be reduced in size in obtaining the same power as before by symmetrically disposing the pair of pistons.

Title: Duplexed configuration device
IPC: G06F11/20
Filed: 1992-03-13
Abstract: PURPOSE:To execute ACT switching without stopping a task processing and to prevent an ACT system from being erroneously confirmed at a host device by executing ACT switching after queue data are eliminated. CONSTITUTION:When an ACT switching request is generated from the host device, a CPU 11 or 16 in the ACT system activates a monitor task as ACT switching preparation. Each time the processing task completes the processing, this monitor task is activated and monitors the presence/absence of queue data. When the queue data are eliminated, ACT switching preparation completion is outputted to a bus control circuit 15 or 20. The bus control circuit 15 or 20 executes ACT switching by controlling suitable bus transceivers 21-23, and the CPU 11 or 16 are informed of ACT switching and at the same time, the host device is informed of ACT switching completion. When ACT switching is informed, the CPU 11 or 16 starts a normal processing. Therefore, it is not necessary to copy the queue data, and ACT switching is enabled without stopping the task processing.

Title: Sealing mechanism between metal and ceramics
Inventor: NISHIZAWA JUNICHI
IPC: F16J15/10
Filed: 1987-04-13
Abstract: PURPOSE:To maintain perfect sealing even if the temperature change is repeated, by inserting a soft metal sealing member into between a metal member and a ceramics member and attaching a sealing assisting member for offsetting the thermal expansion of metal onto the sealing member. CONSTITUTION:A ceramics valve seat 1B is constituted by inserting a soft metal ring 6 between a gas casing 5 which contacts the valve seat 1B and a standing base and installing a cylindrical sealing assisting member 7 consisting of an invar behind the metal ring 6. When stainless steel is used for metal member, Fe-Ni alloy having a low expansion rate is suitably used for the sealing assisting member. Though thermal expansion is generated in each part, and the expanded sealing material is introduced into the expanded sealing gap, and sealing is maintained, sealing material is introduced also into the generated gap, since the thermal expansion of the assisting material 7 is small, and the swelling-out rate into the parts between the ceramics valve seat 1B, metal member 5, and a member 8 is little. Therefore, the deformation applied onto the sealing member is small, and the sealing of the ceramics valve seat can be perfectly maintained for a long period.

Abstract: PURPOSE:To increase the value of N (the number of outputs of multi-phase clocks by adding a shift register and at the same time to decrease the value of N by giving a certain order bit of the outputs of the shift register to an OR gate. CONSTITUTION:A reset signal is set at a high level and is also used to a clear input of a shift register 5 to clear all bits of the output of the register 5. At the same time, an FF3 is set via an OR gate 4, and the output of the gate 4 is set at a high level. Therefore, the series input of the register 5 is set at a high level. When the reset signal is set at a low level, the first bit of the register 5 is set by the first clock that is supplied to the register 5. Then the output of the register 5 is set at a high level, and the FF3 is reset. Therefore the first bit of the register 5 is reset by the next clock, and the output of the register 5 is set at a low level. The clocks are successively supplied, and the N-th bit of the register 5 is set at a high level. Then the FF3 is set again. Then the first bit of the register 5 is set again, and the output of the register 5 is set again at a high level.
