Title: Seal system for hydraulic machine
Inventor: NAGAFUJI TOMOTAKE
IPC: F03B11/00
Filed: 1983-09-06
Abstract: PURPOSE:To keep a magnetic fluid stably in a seal part as well as to improve sealability ever so better, by installing an annular projecting part in the side of a runner, and also installing magnetic circuits at both sides of the projecting part with both opposed, while making up a pocket part, which collects the magnetic fluid, on the tip. CONSTITUTION:In case of a hydraulic machine, for example, a Francis turbine, an annular projecting part 18 being projected in a horizontal direction is solidly installed in the upper peripheral part of a runner band 16. And, at the upper and lower surface positions of the projecting part 18, each of annular magnetic circuits consisting of a pole piece 19 and a permanent magnet 20 are oppositely installed in a state of supporting a lower cover 17. With this constitution, an interval between the runner band 16 and the lower cover 17 is sealed up with the magnetic circuit and a magnetic fluid 21. In addition, at the tip end of the projecting part 18, a pocket 22 for collecting the magnetic fluid 21 being splattered by centrifugal force attending on rotation in the runner band 16 is formed. According to this method, the magnetic fluid 21 can be stably held in the seal part, thus sealability is improvable.

Title: Feeding method of work
Inventor: INOUE DAIZOU
IPC: B65G1/06
Filed: 1981-10-13
Abstract: PURPOSE:To reasonably align and bring out every fixed number of works supplied in number at random, by setting the pitch in a work feed mechanism for a length between a work supply position and work take-off position. CONSTITUTION:Works 2 are supplied to a rail 1, a work supply position, and fed by a feed mechanism to two pitches in steps m1, m2. Because a sensor 6 detects no work, further one pitch is fed by its signal in a step m3. Then different two works 2 are supplied and fed by two pitches in steps m4, m5. The preceding two works 2 are pressed by the following works 2 and fed by one pitch, then four works are aligned. Because the sensor 6 is left under a condition of no work, the work is fed by one pitch. In this repetition of the above operation, the work 2 numbers 10, if the 10 works 2 are fed by one pitch in a step m18, the sensor 6 detects presence of a work, and the work is brought out.

Title: Lubricating agent for condom and condom using the same
Inventor: KAIYA ATSUSHI
IPC: A61F6/04
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain both a lubricating agent for condom, safe to a human body, excellent in performances, capable of maintaining lubricating properties during use, containing a squalene and a condom stuck with the agent. SOLUTION: This agent comprises a powdery material containing one or more compounds selected from the group consisting of squalene, its partial hydrolyzate and squalane. Squalene is a polyunsaturated compound of the formula. The agent consists of 10-85wt.% of the squalene, 2-70wt.% of a protein, 5-7wt.% of a saccharide or a saccharide compound material and 0.1-20wt.% of an emulsifying agent and/or a stabilizer as main components. Since the lubricating agent comprises powder and the squalene, and the squalene is gradually released from the powder, moderate lubricating properties are obtained during use. Since the powder is mixed in the agent, handleability in the production of a condom is excellent. Squalene has cell activating effects, antiinflammatory effects and male and female hormone activating ability and is useful for a lubricating agent for condom.

IPC: H01L29/74
Filed: 1986-07-14
Abstract: PURPOSE:To prevent any short circuit between gate and cathode, a current interruption failure and an element breakdown due to collapsed electrode from occuring while reducing the pressure welding load per unit space upon cathode electrode in case of pressure welding both surfaces by a method wherein a conductive space in a semiconductor substrate of a gate turn-off thyristor GTO for electron is expanded. CONSTITUTION:Cathode emitter layers 5 are arranged in tripple ring type on one semiconductor substrate 1. Each ring contains multiple GTO units 8 divided and encircled by a gate electrode 9 while the cathode emitter layers 5 and cathodes 8 in respective units GTO 8 encircled by the gate electrode 9 are further divided into many parts.

Abstract: PURPOSE:To control running of a vehicle according to the driver's requirement by forbidding acceleration slip control by means of a throttle driving means, when an acceleration pedal is largely operated on a high mu road surface, and driving wheels are intentionally slipped so as to vary the direction of a vehicle. CONSTITUTION:A throttle driving means is constituted in such a way as to open and close a throttle valve 11 by a step motor 50 via a clutch 40. An acceleration operation mechanism is constituted in such a way as to open and close the throttle valve 11 according to operation of an acceleration pedal 34, and a motor 50 is controlled by a controller 100. Under this control, driving road surface mu is judged by a slip rate of driven wheels. When overslip of the driving wheels is detected and a road surface condition is the height mu, and operation quantity of the acceleration operation mechanism is equal to a specified quantity or more, acceleration slip control by a throttle driving means is forbidden, and the throttle valve 11 is driven according to the operation quantity of the acceleration operation mechanism. Thus the direction of the vehicle can be controlled by intentionally slipping driving wheels.
