Title: Local area network of csma/cd system
Inventor: MURONO TAKAHIRO
Filed: 1987-10-31
Abstract: PURPOSE:To prevent collision at the time of re-transmission of data by enabling only a station receiving its own station address to perform the re-transmission of the data when the collision is detected. CONSTITUTION:A priority order decided in advance is applied after the collision is generated, and a network access right is attached on a station with the highest priority order out of network media access controllers(NMAC)14-0-14-3 in stations detecting the collision in transmitting the data. And only the station on which the access right is attached can perform the re-transmission of the data. Thus, the re-transmission of the data (packet) after the collision being generated is limited to one station. In such a way, the regeneration of the collision of the data can be evaded, and an average data re-transmitting time can be shortened, and it is possible to prevent the transfer capability of the data due to the increment of the number of stations to be connected to a network from being lowered and to improve the throughput of the whole of the net work.

Title: Sheet resist device
Inventor: KANEMITSU SHINJI
IPC: B65H9/14
Filed: 1987-10-31
Abstract: PURPOSE:To prevent the bending damage of a corner part due to an unreasonable conveyance force exerted on the corner part, by a method wherein the sheet conveyance force of the outer roller pair of a plurality of roller pairs situated in a direction extending at right angles with a conveyance direction is decreased to a value lower than that of the inner roller pair. CONSTITUTION:An oblique running sheet S is conveyed from the upper stream to a resist roller pair 7 in a state to be held between nips formed by conveyance roller pairs 2, 2, 2, and 2, and when a left corner part Sa of a tip is forced into contact with the roller pair 7, the roller pairs 2, 2, 2, and 2 are stopped as a conveyance force is exerted on the sheet S. A rotation moment M is generated around the corner part Sa by means of a synthetic conveyance force F of the roller pairs 2, 2, 2, and 2, and when the sheet S is rotated counterclockwise to bring the whole width of the tip into contact with the roller pair 7, rotation is stopped. In which case, since the conveyance force of the roller pairs 2 and 2 on both sides of the roller pairs 2, 2, 2, and 2 is lower than that of the roller pairs 2 and 2 at a central part, an unreasonable force is exerted on the corner part Sa of the sheet S to prevent bending of the corner part Sa and production of wrinkle thereat.

Title: Mechanism for discharging liquid
Inventor: SHIRAKI SHUZO
IPC: B65D47/06
Filed: 1988-11-01
Abstract: PURPOSE:To prevent liquid from leaking by providing a liquid path for discharging liquid from a device on a body, wherein a passage part having a first opening opened at an opening end and a second opening located above the opening end are included so that liquid is guided upward from the opening end at a mouth part. CONSTITUTION:Liquid 2 contained in a vessel body 3 does not flow out of a vessel 1 since pressure inside 5 the vessel body 3 functioning to a liquid level 48 and atmospheric pressure functioning to a liquid level 49 are balanced. When the vessel body 3 is pushed and deformed, pressure inside 6 the vessel body 3 functioning to the liquid level 48 becomes larger than the atmospheric pressure functioning to the liquid level 49 so that the liquid 2 passes through a path 20 over an opening 22 of a path 18 and is poured out from an outlet 24. Then, if pressing the vessel body 3 is released, the body 3 restores to its original shape due to elastic force of the body 3, reducing pressure inside 5 the vessel body 3 functioning to the liquid level 48. This allows a part of the liquid 2 remaining in the path 20 to flow back in a direction opposite to that indicated by an arrow 19 and return to the path 18, where balanced state is restored again to have the liquid level 49 placed at the path 18.

SOLUTION: A regulation main valve 61 of a pressure regulation device 60 is opened. As a result, the secondary side gas led in to the pressure regulation device 60 from the cylinder upper chamber 11a of a pressure reducing valve through a secondary side gas feeding pipe 22 is discharged from the escape valve 64 of the pressure regulation device 60 into the atmosphere. When the regulation main valve 61 of the pressure regulation device 60 is released and the escape valve 64 is closed, the secondary side gas led in to the pressure regulation device 60 is led in to pressure regulation chambers 9a and 9b through a secondary side gas feeding pipe 23. Consequently, the gas in the pressure regulation chambers 9a and 9b is discharged from the escape valve 15 of the pressure reducing valve into the atmosphere, and it is replaced to the secondary side gas.

IPC: F02D41/22
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To detect a fault in a fuel metering field completely and easily by detecting the defect of a fuel metering system when boost pressure is deviated from an expected value in a self-ignition type internal combustion engine. SOLUTION: A sensor 196 is disposed at the delivery side intake conduit 105 of a compressor 190 connected to the turbine 180 of a turbocharger fitted onto an internal combustion engine through a drive part 195. Its detected signal is inputted in a control circuit, and the pressure (boosting pressure) of the intake conduit 105 and/or a pressure change is detected, which is then used as a measure for fuel injection control. The condition where no fuel injection is conducted in the internal combustion engine, for example, fault detection is conducted at the time of engine brake operation. Namely, it is checked if boosting pressure is deviated from an expected value (threshold value), and if not, it is detected as fault generation. Or, if the rotational speed of the internal combustion engine rises higher than a permissible change preset depending upon a control signal, it is detected as fault generation.
