Filed: 1982-11-12
Abstract: PURPOSE:To obtain a switch stable to temperature increase by using an extremely fine multi core superconductive wire composed of only an Nb3Sn superconductor for a conductive wire for a necessary thermal type superconductive switch, when a superconductive electromagnet is operated by permanent current. CONSTITUTION:Many pieces of Nb3Sn superconductors 1 are buried in a CuSn matrix 2 into the superconductive wire 3, and an obtained tape is kept heat- treated. Next, it is wound by desired turns, and this switch is buried in a heat- resistant resin 5 with a switch-off heater. Thereafter, this switch is connected to a superconductive coil; at this time, bend, etc. may generate at lead-out parts 4 and cause the superconductive characteristic at these parts to deteriorate. However, since these lead-out parts 4 exist outside the resin 5, cooling by liquid helium is good, and accordingly the deterioration of the superconductive characteristic is compensated.

Title: Polishing method for vehicle
Inventor: OTANI HARUO
IPC: C09G1/00
Filed: 1988-08-08
Abstract: PURPOSE:To polish a vehicle highly and uniformly and to keep wax from adhering to a window glass by depositing wax like white powder on the surface of a car body and subsequently wiping out the wax by hands or rubbing same by a car washing brush. CONSTITUTION:Wax made by emulsifying silicon compounds and wax as essential component by one, two or more anionic surface active agents selected from sulfate ester group, a sulfonate group and a fatty group is applied to the body of a vehicle by a portal car washing machine, the body is brushed by a car washing brush, and then dried. Thus, the wax is made like white powder, so that when the wax is wiped by manual wiping work or using a car washing brush, high-grade polishing effect can be obtained. Furthermore, as the wax deposited like white powder is applied only to the coating surface of the car body, there is no deposit on a window glass. Accordingly, it is recognized that the wax will not adhere to the window glass.

Filed: 1994-07-29
Abstract: PURPOSE:To maintain the excellent tensile strength of a polypropylene tape, in which warp and weft are monoaxially stretched, as it is, to increase the fusion strength of the intersection's of warp and weft, and to simplify even manufacture and mass-produce high-strength net bodies efficiently. CONSTITUTION:Coated tapes, in which a thermoplastic resin capable of being extruded at 160 deg.C or lower and having a low melting point is extruded-coated or laminated and unified on the peripheries or both upper and lower surfaces of monoaxially stretched polypropylene tapes, are used as warp 1 and weft 2, these warp 1 and weft 2 are crossed mutually at regular intervals, and each intersection is fused by a means such as ultrasonic fusion. Since the coated tapes used as warp and weft are coated with the thermoplastic resin having the low melting point or laminated and unified, the polypropylene tapes as core materials are not thermally deteriorated at the time of coating or laminating, and the intersection can be fused firmly under the conditions of gentle fusion, thus also preventing the heat deterioration of the polypropylene tapes as the core materials at the time of fusion.

Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To provide a controller of a linear solenoid which allows the improvement of the control responsiveness, without increasing the number of samplings of a detection signal. SOLUTION: A switching element TR, which turns a current path of a linear solenoid L on and off, is controlled by a PWM signal generated by a drive circuit 10.

The smoothing circuit 14 supplies a detection signal with no delay which corresponds to the drive current to the microcomputer 16 via a bypass B for a transient period, in which a target value for the drive current is changed and therefore the drive current is much changed. During the other period, it supplies a detection signal, having a stabilized signal level to the microcomputer 16 via an integration circuit consisting of a resistor R4 and a capacitor C.
