Title: Bearing structure in rotary connector device
Inventor: MATSUMOTO TSUYOSHI
IPC: B60R16/02
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To enable the installation of bearings with the diameter of a shaft part shortly held by forming a thrust bearing and radial bearing structure on the shaft part of a rotor housing. SOLUTION: The shaft part 27 at its lower end of a rotor housing 2 is provided with a bearing part 28 having semi-circular cross section over the entire periphery. The bearing part 28 slidably contacts of the receiving part 123 of the bottom housing 12 to form a thrust bearing. An attachment 3 forms a grooved grease reservoir 33 over the entire periphery of the contact surface against the bottom housing 12. Filling grease in the grease reservoir 33 reduces rotary resistance evolved between the attachment 3 and the bottom housing 12. The attachment 3 slidably contacts the inner circumferential surface 124 of the bottom housing 12 to form a radial bearing. Thus, bearings are provided with the diameter of the shaft part 27 shortly held; the length of a flexible cable wound on the shaft part 27 is shortened as well.

Title: High speed multiplier
Inventor: NAGAMATSU MASATO
IPC: G06F7/52
Filed: 1990-07-17
Abstract: PURPOSE:To reduce the repeating operation frequency and to simplify the constitution of a multiplier by using the algorithm of a booth to simultaneously refer to plural bit strings of a multiplier and to collectively evaluate the partial products of these bit trains. CONSTITUTION:A decoder 5 scans a multiplier and sends the control signals to the selectors 7,9,11 and 13. These selectors obtain the values by multiplying a multiplicand by 2,2-1,1,-1 and 'O' respectively and output either one of these values to a 4-2 compressor string 15. This output value is added to the train 15 by a full adder 17, and the added values are held by a register 19 and then transferred to a shifter 21 to be shifter there. In a 2nd cycle the partial products are outputted from the selectors 9,11 and 13 and the contents of the shifter 21 are outputted from the selector 13. These outputs are added to the train 15 by the adder 17 and held by the register 19 and then sent to the shifter 21. In the 3rd-5th cycles, the processing operations equal to that of the 2nd cycle are repeated. Then the result of addition is obtained by the shifter 21 in the 5th cycle.

Title: Method and device for treating metal adhesion in nuclear power plant
Inventor: ISHIDA RYOICHI
IPC: G21D1/00
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To prevent metal from adhering to nuclear fuel by carrying out a part or the whole process of metal adhesion, with the nuclear fuel removed from the inside of a reactor, or in the air in the range where metal does not adhere to the nuclear fuel in the reactor. SOLUTION: A reactor pressure vessel 1 is sealed with a lid, and reactor water is located higher than the piping 3 for a feedwater system. The reactor water heated by nuclear fuel is vaporized, passes through a steam separator and a steam dryer and reaches an electric generator in the piping 7 of a main steam system. After the lid for a reactor pressure vessel is opened and the steam separator, the steam dryer and the nuclear fuel are taken out from the inside of the reactor, the level of the reactor water is lowered to the bottom of the reactor, and the treatment for metal adhesion is carried out. For example, an adhesion chemical prepared by dissolving fatty acid salt of a metal that is allowed to adhere to the nuclear fuel in an organic solvent is used for the treatment for metal adhesion.  The fatty acid salt forms colloid in the organic solvent, so that it can easily adhere to a surface to be treated. A device 8 for sprinkling the adhesion chemical is mounted on the top of the reactor, and the adhesion chemical is sprinkled from a supplying part 8a of the device 8 to allow the metal to adhere to required positions.

Title: Recording disk reproducer
Inventor: IYONO EIICHI
IPC: G11B17/049
Filed: 1981-11-24
Abstract: PURPOSE:To avoid the breakage of a pickup element which is due to the collision against a jacket, etc., by holding a stylus at the 3rd position higher than the 2nd position at all times excepting a period during which a side detecting switch is connected to the NO and a turntable is moving up. CONSTITUTION:When a jacket is inserted through a slit, a shutter switch 41 is switched to the NO side and then a side detecting switch 42 is switched to the NO side. Thus the transistors 72 and 73 are turned on, and a current corresponding to the difference of potential between power supplies +B1 and +B2 is supplied to a coil 402. A stylus 37 is positioned at a higher position by the force obtained by adding the elastic force of a plate spring 39 and the electromagnetic force of a plunger 40. This state is kept until an empty jacket is taken outside a player. A switch 69 is switched to the NC side while a turntable moves up and the performance is carried out. Then the stylus 37 is held by only the elastic force of the spring 39.

Title: Comparative controller of output by gas combustion
Inventor: YAMAGATA HIROSHI
IPC: F23N1/00
Filed: 1980-12-29
Abstract: PURPOSE: To make possible control of the pressure loss of the piping, scattering in diameters of the piping and nozzles, the back pressure by a structure wherein  a back pressure chamber of the captioned device using a governor mechanism  and an ellectromagnetic valve is connected to the gas passage up to the combustion chamber including the burner through a bypath.  
     CONSTITUTION: The back pressure on a back pressure chamber 13 is controlled through a passage 16, a throttle valve 17 by turning an electromagnetic valve 9 on or off. By this method, as a diaphragm 1 moves up and down a main valve body 5 is oscillated vertically to open and shut a valve port 4. In this case, the gas flow from an inlet 7 is branched and comes into the back pressure chamber 13 through a governor 20, a valve hole 11 of the electromagnetic valve 9, a passage 14, an orifice 15, a throttle valve 17 and part of the gas flow runs a bypath pipe 18 to an outlet 3. In this manner, if the switching cycle or time of the electromagnetic valve 9 changes, the back pressure changes and enables the flow rate of gas passing the valve port 4 to be controlled comparatively by the governor mechanism. In this manner, the pressure loss of the piping, the scattering diameters of the piping and nozzles, the back pressure can be controlled.

Title: Oil sealing structure of bearing part
Inventor: TAKEDA AKIYOSHI
IPC: F16J15/44
Filed: 1993-07-30
Abstract: PURPOSE:To reduce a leak of lubricating oil inexpensively by forming at least one groove on the surface of a turning shaft to be opposed to the through part inner surface of an oil thrower spilally along the circumference. CONSTITUTION:Oil stuck to the surface of a turning shaft 11 is gradually shifted by rotation of this shaft 11, reaching to an oil thrower 12. At this time, a leak of lubricating oil is preventable owing to plural pieces of grooves 14a to 14c formed on an inner surface of a through part 13 of this oil thrower 12. Simultaneously with this, since a spiral groove 16 advances toward an inner part of the oil thrower 12 by rotation of the turning shaft 11, the lubricating oil stuck to this turning shaft 11 is able to be put track back to the inner part along the groove 16. In addition, the groove 16 functions as a fan to the vapored lubricating oil, thereby pushing this vapored oil back to the inner part. Thus, the leak of the lubricating oil is made reducible in an inexpensive way.

Abstract: PURPOSE:To prevent an upper and a lower electrode from being short-circuited at a light shield layer part by forming the light shield layer of the 1st light shield layer which contains a conductive material and the 2nd light shield material made of only a non-conductive material. CONSTITUTION:A part 8 where powder of a conductive pigment coagulates in the 1st light shield layer 3 increases the thickness of the light shield layer to form a projection structure. The 2nd light shield layer 4 is laminated on the 1st light shield layer 3. Therefore, even if an electrode 2B on a lower substrate contacts a light shield layer formed on an upper substrate at the time of the application of pressure to the substrates of a liquid crystal display element, the electrode that this electrode contacts is the 2nd light shield layer 4 which has no conductivity, so the upper and lower electrodes 2A and 2B are never short-circuited.
