Filed: 1986-06-25
Abstract: PURPOSE:To obtain a plastic diaphragm which is light and has high rigidity and whose efficiency and reproduction frequency limit are high and where the distortion of form hardly occurs and the distortion of sound occurs little by constituting it with polyester film which isn't drawn or drawn by at least uniaxially including polybuthleneterephtalete component with >=50 wt.%. CONSTITUTION:A film which mainly consists or polybuthleneterephtalete (PBT) and has lower Young's modulus than polyethyleneterephtalete is selected as diaphragm material and in order to keep its compatibility and the feature as PBT, the PBT component is more than 50 wt.%, >=60 wt.% is preferable. PBT system resin which is used in such case, is consisted essentially of PBT polymerized with terephthalic acid and 1, 4-butanediol and means a copolymer with other polyester and/or the blended one.

Title: Manufacture of thermoplastic elastic elastomer belt
Inventor: YAMAMOTO KAZUYUKI
IPC: F16G1/21
Filed: 1979-11-16
Abstract: PURPOSE: To make the belt absorb the unevenness due to the flexture of the surface and uniformalize the thickness by a method wherein both surfaces of a laminate formed of synthetic fiber woven fabric and elastomer are covered with release sheets of low elasticity, later are formed in one body by heat and pressure, and are further cooled in the state of tension.  
     CONSTITUTION: The release sheets 1 and 1' of low elasticity, such as paper, are stuck on the laminate 2 formed of the heat-shrinkable synthetic fiber woven fabric 4 and the thermoplastic elastomer 3, such as, for instance, a laminate 2 formed of polyester canvas and urethane rubber and later are introduced into a vulcanizing device B and vulcanized into one body under heat and pressure. Moreover, the molded article thus vulcanized is given tension within the range of extension of the release sheets 1 and 1' and in this state is rolled round a rolling device C. In this way, the uniform thickness is obtained by sticking the release sheets of low elasticity, since thereby the change in the direction of length is made to be small and the change is limited only to that of the thickness caused by the heating and pressing process. In addition, the surface of the belt is made smooth and even since the release sheets absorb the unevenness of a vulcanizing drum, etc.

Title: Device inspecting method, and device inspecting device
Inventor: TSUJI DAISUKE
IPC: G01R31/26
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To suppress the substrate cost and the working man-hour by eliminating a jumper or the like from a substrate, and to improve the inspection efficiency. SOLUTION: When a probe needle is abutted on a plurality of test pins 4, a device inspection device 1 outputs the stand-by signal 1h to a specified terminal 21 of an ASIC 2. The ASIC 2 receives the stand-by signal 1h from the device inspection device 1 to set the impedance to be high between devices 3 to be inspected. When the impedance between the ASIC 2 and the devices 3 to be inspected is high, the device inspection device 1 outputs the inspection signal 2h to the probe pin abutting on the test pin 4. The device inspection device 1 judges whether or not the device 3 to be inspected is normal based on the inspection signal 2h outputted from the device to be inspected.

Title: Duplex system of loop transmission line
Inventor: NAKAGAWA SATORU
Filed: 1984-07-20
Abstract: PURPOSE:To cope with a fault with proper changeover of a switch when a fault occurs by transmitting cyclically and simultaneously the same data to the 1st and 2nd transmission lines and monitoring the output of the switch that switches data of both transmission lines. CONSTITUTION:Transmission controllers 11-15 are connected in a loop form via data transmission lines 21 and 22 and transmit the same data cyclically and simultaneously to both lines 21 and 22 according to a fixed order and in the opposite directions to each other. Each controller contains interlocking switches 41 and 42 for transmission/reception of input/output 21-1, 21-2, 22-1 and 22-2, a reception switch 43 for data supplied from both lines 21 and 22, a data receiver 36 which monitors the output of the switch 43 and controls its working and a data transmitter 37. When the output of the switch 43 is normal, the receiver 36 switches the switch 43 periodically. Then the output of the switch 43 has a drop- out when the data transmission line has a fault. Thus either one of controllers 11-15 switches the switch 43 according to the place where the fault occurs.

Title: Switch circuit
Inventor: TAKEMURA NAOKI
IPC: H01H9/54
Filed: 1994-06-30
Abstract: PURPOSE:To reduce effects by capacity between terminals of an element by a simple circuit, and achieve switching of a high frequency signal by providing a capacity circuit to let a leak signal of the high frequency signal escape in accordance with opening action of a switching element. CONSTITUTION:When a switching element S1 makes opening action, a capacity value of a variable capacity VC is increased by a control input from a control line CL1. A leak signal transmitted to a signal line L2 from the signal line L1 through a parasitic capacity Cs is thus let to escape to a grounding line. When the switching element S1 makes closing action, the capacity value of the variable capacity VC is reduced by the control input from the control line CL1, an input signal from a signal source 1 can be transmitted to the work 2 side almost without damping. In such a simple constitution, transmission/ disconnection of a high frequency signal can be performed, thereby a space for installing a switching circuit can be small.

Abstract: PURPOSE:To eliminate relative position deviation between the upper and lower heads produced before and after alignment control and to decrease control manhour by drilling a control hole through a leaf spring and forming a hole to a fixed carriage as a fulcrum of a control jig. CONSTITUTION:A jig fulcrum hole 14c containing a fulcrum round hole 14d through which a tip 19a of a square pillar-shaped jig 19 is inserted is formed at the bottom part of a fixed carriage 14 at a position near a screw hole 14b. While a control square hole 12b through which the jig 19 is inserted is formed to the leaf spring 12 at a position opposite to the hole 14c and in a smaller size than the hole 14c. Thus the jig 19 is inserted to the hole 14c of the carriage 14 and the inside of the hole 12b of the spring 12 can be pushed horizontally by the side surface of the jig 19. As a result, the position control is attained between the upper end lower heads 10 and 13 without unfastening a screw 16. Thus it is not required to control again the position deviation between both heads 10 and 13 by fastening the screw 16 again. Then the control manhour is decreased.
