Title: Internal combustion engine
Inventor: KANEKO KATSUNORI
IPC: F02B75/18
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To aim at improving both engine performance and quiteness while maintaining constant displacement. SOLUTION: An engine is provided with cylinders 2a, 2b for actual combustion and a cylinder 4 for torque balance rather than combustion. Each capacity of the cylinders 2a, 2b is expanded since the bore of the cylinder 4 for torque balance is reduced. As a result, combustion efficiency and gas pressure torque of those cylinders 2a, 2b can be improved. During running of the engine 1, only air cycling is executed within the cylinder 4. The expansion pressure torque of the compressed air produces maximum torque substantially equal to that of those cylinders 2a, 2b. Even when the number of cylinders for combustion is reduced to two, the resultant torque balance characteristics can be substantially the same level as that of the 3-cylinder engine.

Title: Synchronous moving device for catcher-position correction function
Inventor: NOMURA TORU
IPC: B26F3/00
Filed: 1992-01-27
Abstract: PURPOSE:To effect synchronous movement of a catcher to a proper position by correcting a catcher position in conformity with the angle of inclination of a nozzle in case the nozzle is inclined in a water jet machining device. CONSTITUTION:A synchronous moving device is one in which a nozzle 6 able to have its inclination angle set and a catcher 4 are interlockingly moved in same quantity in the same direction by a single drive source, and in which position-correcting cylinders 10, 11 are disposed between a catcher moving belt 2 and the catcher 4. A cylinder rod is expanded and contracted in a direction in which the catcher 4 is moved. By operations of the position-correcting cylinders 10, 11, the catcher 4 is controlled to be moved to a proper position at an opposite side to a side where the nozzle 6 is inclined. By this, a distance measuring until a jet impinges upon an inner wall of the catcher 4 can be made large.

IPC: G03G15/16
Filed: 1995-02-24
Abstract: PURPOSE: To facilitate jam processing and the attaching/detaching operation of a process cartridge. CONSTITUTION: A supporting frame 17 freely attachably and detachably holding plural process units 18 is freely turnably fitted to a main body 1. The turning direction of the supporting frame 17 at this time is set not in the longitudinal direction along the carrying direction of a form, but in a direction perpendicular to the carrying direction of the form, to enable uniform opening from the upstream side of a form carrying path 4 to its downstream side. At this time, the length of the supporting frame 17 in the carrying direction of the form is shorter than the width in the direction perpendicular to the form carrying direction, so that even if the supporting frame 17 is turned at a comparatively large turn angle, the upper part of the carrying path 4 on the center side of the turn can be opened, while the height of the rising of a free end side is suppressed low.  Further, when the process unit 18 is attached/detached, the rising position of the supporting frame 17 is limited to the attaching/detaching position of the process unit and at the time of processing jamming, the frame 17 is held in a jam processing position being a most rising position, by the operation of a holding mechanism 27.

Title: Fuel intake device for fuel tank
Inventor: ONO JUNYA
IPC: F02M37/00
Filed: 1986-02-20
Abstract: PURPOSE:To enable the easy treatment of generated vapors by providing a suction pipe at the sub-chamber side of a tank body and fitting the suction pipe with a valve closing when a liquid level has dropped below the bulge of the tank body. CONSTITUTION:When fuel is jetted from a nozzle 11, negative pressure occurs within a chamber 10 and vapors generated in an upper space 'S2' at the sub- chamber side are sucked into the chamber 10. Concurrently therewith, vapors flow into an upper space 'S1'. And when a liquid level has dropped below a bulge 2, a communication hole 16 is closed and a suction effect for vapors from a suction pipe 14 is interrupted, thereby causing a liquid flow toward a main chamber 4 due to the effect of an ejector 9. Consequently, it becomes possible to transfer vapors in the upper space 'S2' at the side of the sub- chamber 5 to the upper space 'S1' at the side of the main chamber 4, and treat vapors easily.

IPC: F04B49/02
Filed: 1989-02-17
Abstract: PURPOSE:To check the reverse rotation of a compressor at time of its stoppage by installing a drive circuit feeding an electric motor with a driving current, and a connection selector means selecting one side of connection with an exciting coil and each closed-circuit loop of exciting coils themselves. CONSTITUTION:When a compressor 11 is driven, a drive starting signal is transmitted to a connection selector circuit 16 from a drive circuit 17, and contacts A and B of a switch 16a, contacts D and E of a switch 16b and contacts G and H of a switch 16c are all connected to one another. When the compressor 11 is stopped, a drive stopping signal is transmitted to the connection selector circuit 16, while the switch 16a release its contact, and contacts D and C of the switch 16b and contacts G and F of the switch 16c are connected to each other. Consequently, exciting coils 121 - 123 are joined into connection and the compressor 11 comes to a stop. When the compressor 11 is stopped, reverse directional force acts on a movable scroll body of a compression zone 13 due to a difference between suction pressure and discharge pressure. Counter- electromotive force is generated in an exciting coil 12a by reverse rotation, whereby normal rotational force acts on a motor 12, thus reverse rotation of the movable scroll body is kept back.
