Title: Piston of internal combustion engine
Inventor: TSUSAKA YOSHIHIKO
IPC: F16J9/28
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent wear from being produced on a resin made piston ring by the pushing to a land and flattering, in the piston of an internal combustion engine. SOLUTION: The contact area of an outer ring 2 pushed to a third land 24 by a combustion pressure is a bigger area (shown by S2) than an usual area (shown by S1) due to that the diameter of the third land 24 is bigger. Therefore, the contact pressure of the outer ring 2 to the third land 24 is dropped even in the same combustion pressure. Therefore, the wear of the outer ring 2 can be prevented.

Title: Oil-removing and volume-reducing device
Inventor: MIYASAKA ATSUSHI
IPC: B09B3/00
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To remove oil and reduce the volume of an oil residual container in which oil is left behind by providing a pressurization chamber surrounded by a closable lid part and having a shielding wall, pressing the container to be treated by a hydraulic ram while holding the container with wall surfaces opposite to each other in the pressurization chamber, which leads the dripping oil into an oil receiving tank and a chute which leads the volume-reduced container to a volume-reduced container receiver. SOLUTION: A slide door 15 is opened, and an oil filter to be treated is placed in a container receiver 21. When the slide door 15 is closed, a sensor 16 is operated, a hydraulic unit 28 is started, and a hydraulic ram 17 is advanced by a hydraulic cylinder 18. The oil filter stored in a pressurization chamber 14 is held, compressed and squeezed by the hydraulic ram 17 and a pressure receiving plate 19, and the oil to be discharged is passed through an oil conduit 20 and a drop port 22, and discharged into an oil receiving tank 25. The oil filter which is freed by the retraction of the hydraulic ram 17 is dropped from the drop port 22, slides on a chute 27, and enters a volume-reduced container receiver 26. The scattered oil is stored in the pressurization chamber 14, preventing an external part from being polluted with oil.

Title: Subscriber line access system
Inventor: SHINKAWA HIROSHI
IPC: H04M3/06
Filed: 1985-08-03
Abstract: PURPOSE:To miniaturize and economize a subscriber circuit by using a set of changeover contact points as the call signal transmission and the subscriber line test in common. CONSTITUTION:When the call signal is transmitted to a telephone set 5, the changeover contact point 16 is caused to intermittently act in synchronization with the action of a common changeover contact point 15. Thus, while the changeover contact point 16 is acting, the call signal from a call signal generator 6 is transmitted to the telephone set 5. When the test of a subscriber line 4 terminated through the telephone set 5 is conducted, the changeover contact point 16 is caused to intermittently act in synchronization with the restoration of the common contact point 15. Thus, while the changeover contact point 16 is acting, a tester 13 is connected to the subscriber line 4, whereby the electrostatic capacity test and inter-line insulation/resistance test on the subscriber line 4 can be possible through the tester 13.

IPC: B23K3/00
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To provide an Al alloy brazing filler metal to which a flux is applied with excellent adhesivity, and its manufacturing method. SOLUTION: A surface of an Al alloy member 2 is coated with a brazing filler metal by a thermal spray method, and flux is applied thereto in an Al alloy member 12 to be brazed. In a manufacturing method of the Al alloy member 12 to be brazed, the surface of the hot Al alloy member 2 to be extruded from an extrusion machine 1 is coated with the brazing filler metal by the thermal spray method, and the Al alloy member 12 to be brazed is coated with the flux thereon. Since the molten metal droplet of the brazing filler metal is sprayed in the thermal spray method, the surface of the thermal spray coated brazing filler metal becomes finely uneven, and the flux applied to the uneven surface is firmly adhered to the brazing filler metal by the anchoring effect of the recessed part of the uneven surface.  The member to be brazed can be manufactured with excellent productivity by thermally spraying the brazing filler metal on the hot Al alloy member 2 extruded from the extrusion machine 1, and applying the flux thereto.

Title: Inverter
Inventor: MATSUO KAZUNORI
IPC: H02P27/06
Filed: 1990-06-29
Abstract: PURPOSE:To eliminate a rotational irregularity of an induction motor by sensing a phase voltage generated through the ON-OFF operations of switching devices, and by giving an input signal to a means for insulating signals electrically, when the phase voltage reaches about half the value of an input DC voltage, and further, by making the means output the electrically insulated signal corresponding to its input signal, and furthermore, by correcting the distortions of current waveform in a low frequency region. CONSTITUTION:A sensing circuit 14A senses a phase voltage VU generated through the ON-OFF operations of switching devices 4, 5. When the phase voltage VU reaches about half the value of an input DC voltage, by switching a shunt regulator 13 on, the sensing circuit 14A gives an input signal to a photo-coupler 11. Also, the sensing circuit 14A feeds back, the output signal of the photo-coupler 11 for insulating signals electrically, to a control part 20 of an inverter. In this manner, when the phase voltage VU is sensed at half the valve of the input DC voltage value, voltage fluctuations in a duration Td for preventing a short-circuit are so sensed as to average them, and no deviated signal is outputted from the sensing circuit 14A. Thereby, the distortions of current waveform in a low frequency region are corrected and the rotationl irregularity of an induction motor can be eliminated.

Filed: 1979-12-27
Abstract: PURPOSE: To change the turning displacement of a damper in accordance with the change of a flow rate of fluid and perform the flow regulating operation at high accuracy, by setting the damper in a fluid passage and extensibly equipping a variable coil spring to a pivotal shaft of the damper.  
     CONSTITUTION: In a fluid passage 2 a damper 4, whose sectional shape is formed in almost a wing, is mounted, and a swivelling pivotal shaft 3 of the damper 4 is displaced to the downstream side from a position of the center of gravity. While in the periphery of the pivotal shaft 3 a variable coil spring 8 is oxtensibly provided, and a set ring 5a at an end of the spring to a casing 1 and a set ring 5b at the other end to the pivotal shaft 3 are respectively secured. If fluid flows in the passage as shown by the direction of an arrow mark A, turning force acts upon the damper 4 to turn it in a direction of decreasing an area of the passage because of eccentricity in the shaft of the damper. However, a balancing action of fluid pressure corresponding to a rotary angle with urging force of the spring due to a function of the variable spring 8 enables the flow regulating operation at high accuracy.
