Title: Rubbery elastomer composition
Inventor: TAKAHASHI HIDEO
IPC: C08L51/02
Filed: 1984-04-04
Abstract: PURPOSE:A rubbery elastomer composition for chatter-free wiper blades, prepared by adding a surfactant and a highly water-absorptive resin to a rubbery elastomer composition. CONSTITUTION:A surfactant having a hydrophilic group to one end of the molecule and an oleophilic group at another end (e.g., alkyl phosphate or polyoxyethlene/polyoxypropylene ether) and a highly water-absorptive resin which can absorb water in an amount 100-1,000 times as large as its own weight but which is not soluble in water (e.g., polyvinyl alcohol resin or polyacrylate resin) are added to a rubber to a rubber formulation prepared by, e.g., compounding natural rubber with a vulcanizing agent, a vulcanization accelerator, and other adjuvants. A wiper made of the above obtained rubbery elastomer composition shows such an extremely high affinity for water that the wiper blade scarcely chatters during operation.

Title: Optical fiber cable
Inventor: NIIJIMA MASAYUKI
IPC: G02B6/00
Filed: 1989-03-20
Abstract: PURPOSE:To allow easy riding of the optical fiber cable in the air flow in a pipeline and to facilitate the execution of laying by forming the cable to a flat shape and forming twists in the laying direction thereof. CONSTITUTION:The optical fiber cable 1 is formed to a flat shape and the outer side thereof is coated with a tape coating 11 and a sheath 12. The cable 1 is twisted in the laying direction. This twisting is executed by spirally twisting the optical fiber 10 and the sheath 12 at the time of coating, for example, the sheath 12 on the outer side, by which the cable is formed. Such cable 1 is liable to ride in the air flow B by receiving buoyancy to the air flow B in the pipeline A and, therefore, the position thereof in the pipeline A stabilizes at the time of laying of the cable 1. The rubbing and collision of the cable surface to and against the inside wall F of the pipeline are consequently obviated and the flaw and deterioration of the outside surface are obviated. The laying operation is thus extremely facilitated.

Title: Contamination preventing method of hull
Inventor: KUBO ATSUSHI
IPC: B63B59/04
Filed: 1984-04-05
Abstract: PURPOSE:To always maintain the outer surface of a hull in a biological adhesion preventing condition, by coating a general type antifoul paint on the outer surface of the hull to a larger thickness, and as well by periodically scaling a skeleton layer which has built up during sailing with the use of an underwater cleaner to regenerate the paint coating. CONSTITUTION:A general type antifoul paint coating 1 such as, for example, chlorinated rubber, vinyl group resin (polyvinyl chloride), etc. is coated on the outer surface of a hull to a relatively large thickness of 150-200mu. A biological contamination preventing constituent 4 (copper suboxide, organic tin, etc.) contained in the pain coating is eluted through the medium of a water-swelling type rosin or the like, so that a resin as a color spreading material, such as, (for example, chlorinated rubber, vinyl) is remained in the form of a skeleton layer 3. This skeleton layer 3 is scaled by an underwater cleaner such as, for example, a rotary brush to recover the normal condition of the paint coating. With this method the outer surface of the hull may be always maintained in a biological contamination preventing condition so that it may has a satisfactory surface roughness. Further, the cost of the coating may be made low in comparison with a self-polishing type antifouling paint.

Title: Method for controlling repeater in wire rolling line
Inventor: MIZOGUCHI NOBUMI
IPC: B21B37/50
Filed: 1993-03-26
Abstract: PURPOSE:To improve the quality of a product and to stabilize the operation by fixing the rolling speed of a finishing mill at the downstream of a repeater to the variation of material speed generated in a common line in courses of a rolling line of a wire. CONSTITUTION:When a quantity of loop in the repeater exceeds the upper and lower limits of a band width, the rolling speed is accelerated and decelerated in the downstream line before the quantity of loop plunges again into the band width at a fixed rate of acceleration and deceleration. The downstream line speed when the quantity of loop exceeds the band width and plunges again into it is stored in a speed storage circuit 11. A rate gamma of acceleration and deceleration and a control time T in the downstream lines necessary for thrust- out control of the loop in the center of the band width are calculated from the speed difference and the acceleration and deceleration are controlled at the calculated gamma of acceleration and deceleration and with the calculated time T from the time when the loop plunges into the band width. In this way, when the loop exceeds the upper and lower limits of the band width, the loop can be controlled to be returned to the center of the band width without excerting a forced positional control.

Title: Rotary electric machine of axial ventilation type
Inventor: TAKESHITA MITSUO
IPC: H02K9/06
Filed: 1979-05-30
Abstract: PURPOSE:To eliminate the necessity of any separate driving source and enable fan output to be taken out of either of the ends of a rotary machine shaft by driving a fan with the shaft via a speed increasing device and a slip-controllable electromagnetic joint. CONSTITUTION:When a rotor 3 rotates at speed nx, the output shaft 11 of a speed increasing device 10 comes to have a higher running speed Nx and the driving mechanism of an electromagnetic joint 15 rotates at speed Nx. When the speed nx is lower than the set value thereof no, rated current is supplied to the electromagnetic coil of the device 15. Threfore, a slip mechanism does not actuate and a fan 21 rotates at speed Nx to feed air in arrow direction. When the running speed of a rotor 3 exceeds speed no, the supply current of the electromagnetic coil of the device 15 lowers in accordance with the signal from a comparator 28, and a slip mechanism actuates to lower running speed to Np smaller than Nx and to rotate the fan 21 at speeds Nx-Np. Thereby, the necessity of any separate driving source can be eliminated and fan output can be taken out of either of the ends of the rotary shaft.

Title: Gaseous hydrogen sensor
Inventor: YOSHIIKE NOBUYUKI
IPC: G01N27/12
Filed: 1984-04-06
Abstract: PURPOSE:To increase the sensitivity of a hydrogen sensor by making use of the decrease in the resistance value of tungsten oxide when gaseous hydrogen is absorbed in the tungsten oxide. CONSTITUTION:Two electrodes 2, 3 are formed by vapor deposition of Pt, Pd, Ti, etc. on a substrate. An amorphous WO3 film 4 is provided on the electrodes 2, 3 across said electrodes to 4.0-6.0g/cm<3> packing density. A Pt or Pd layer 5 is provided on a WO3 film 4 to constitute a hydrogen sensor. When hydrogen is grought into contact with the sensor, the hydrogen is absorbed into the film 4 by the catalytic effect of the Pt layer 5. The resistance value of the film 4 is consequently decreased and the resistance between both electrodes 2 and 3 is decreased. The hydrogen is thus absorbed more into the WO3 film and the resistance is lower as the concn. thereof is higher. The hydrogen is detected with high sensitivity.

Title: Exhaust equipment for emergency in reactor building
Inventor: OSHIMA KOICHIRO
IPC: G21C9/00
Filed: 1990-03-22
Abstract: PURPOSE:To enable prevention of a leakage of air having the possibility of radioactive contamination even when a reactor accident occurs, by connecting an exhaust fan of a regular ventilation system and a drier of an emergency gas disposal system together by an air duct provided with a switching valve. CONSTITUTION:When an accident occurs in a reactor, air 18 sent under pressure by an exhaust fan 7 proceeds to an air duct 22, and the quantity of air passing through an exhaust valve 9 at a normal time presses a switching valve 23. Since the switching valve 23 is fully opened instantaneously by an air pressure exceeding a normal level, then, the air 18 passes through this switching valve 23 and further a flow control valve 24 and reaches the upstream side of a drier 12. Due to the presence of a check valve 25, in this case, the air 18 flows into the drier 12 inevitably. Accordingly, the air does not return into the atmo sphere in a reactor building again through a flow control valve 11 and an inlet valve 10 and lower a negative pressure in the reactor building 1, and thus a leakage of the air having the possibility of radioactive contamination can be prevented.
