Title: Current lead of superconductive coil device
Inventor: TOYODA KATSUYOSHI
IPC: H01L39/02
Filed: 1986-01-09
Abstract: PURPOSE:To conduct a current stably without causing superconductivity breakdown, by forming a surface-area expanded part at the end part of a lead, which is connected to a superconductive wire. CONSTITUTION:At a lower end part 5 of a current lead, an irregular part 13 as a surface-area expanded part is formed. Thus at the current lead, supercritical pressure helium flows into a sheath tube 2 through a helium introducing pipe 3, and a superconductive wire 1 is cooled. When the supercritical pressure helium flows into the sheath tube 2, the helium flows down along the surface of the irregular part 13 having a large heat transfer area. Therefore, the lower end part 5 of the current lead is sufficiently cooled. The surface-area expanded part having the large heat transfer area is formed at the end part of the current lead having a large quantity of Joule heating and connected to the superconductive wire. Therefore, the end part of the current lead can be sufficiently cooled even with the supercritical pressure helium, whose cooling ability is low. A current can be conducted through a superconductive coil stably without causing superconductivity breakdown.

Title: Safety valve for battery
Inventor: KURAKI JIYUNJI
IPC: H01M2/12
Filed: 1983-01-07
Abstract: PURPOSE:To provide a safety valve which works even during rapid gas generation and has a sufficient gas-discharging ability. CONSTITUTION:After a valve chamber is constituted of a plate-like sealing plate 1 having a valve hole which is to be constantly blocked with a valve body and a cap-like terminal plate 3 attached to the top of the sealing plate 1 by welding or caulking, a valve body 4 made of a synthetic rubber is enclosed in the valve chamber so as to block the valve hole 2. The valve body 4 used here consists of an almost spherical section 4a for blocking the valve hole 2 and an annular section 4b continuous with the upper end of the section 4a and having such a size as to be brought into contact with the inner surface of the cap 3. It is necessary to restrict the volume of the valve body 4 to 50-70% of the internal capacity of the valve chamber, since the deformation of the valve body 4 can not follow sudden increase in gas pressure if the volume of the valve body 4 exceeds 70% of the internal capacity of the valve chamber and increased variations in operation voltage are caused during manufacture resulting in a deteriorated manufacturing yield if the volume of the valve body 4 is less than 50% of the internal capacity.

Title: Torsional damper
Inventor: KAKEGAWA MASATOSHI
IPC: F16F15/167
Filed: 1988-01-07
Abstract: PURPOSE:To get rid of any variation in torsional vibration control as well as to make amplitude control performable even at a high speed range by forming a recess, where at least two inertial rings enter, in a plate, and also forming a clearance, sealing a viscous fluid, between both sides of the plate and these inertial rings. CONSTITUTION:Recesses 2A-2C, where a part of full of at least two inertial rings 3, 6 enter, are formed in a plate 2, and at least two clearances 13, 14, where a viscous fluid 15 is sealed, are formed between both sides of the plate 2 and these inertial rings 3, 6. Thus, not only elastic bodies 4, 5, 7 and 8 but also the viscous fluid 15 are used, and at least these two inertial rings 3, 6 are used, so that even at a high speed range, vibration damping capacity can be brought into full play. In addition, since the clearances 13, 14 are formed between the plate 2 and these inertial rings 3, 6, it comes to a uniform, accurate one as in design data, and thus any variation at each product can be eliminated in a damping function.

IPC: G01F5/00
Filed: 1982-01-13
Abstract: PURPOSE:To eliminate errors in measurement due to pulsation in intake air and blow back of air, by making the length of a bypass three times or more with respect to the distance between the inlet port and the outlet port of the bypass, and opening the outlet port of the bypass so as to face the downstream of a main air intake path. CONSTITUTION:An outlet pipe 15 is protruded to the central part of the main air intake path 2, and the outlet port 8 is provided at the lower surface thereof. The distance l between the inlet port 6 and the outlet port 8 of the bypass 5 is 3-4 times the interval L between both end parts of the bypass 5 in the main air intake path 2. Therefore, an inertial delaying effect is imparted to the air flow in the bypass. Since the outlet port 8 of the bypass 5 is opened so as to face the direction to which the dynamic pressure of the reverse flow is acted, the forward air flow in the bypass at the time of blow back is suppressed, and the errors in the measurement can be decreased.
