Title: Method and device for testing friction and wear of tape
Inventor: AKAHA NAOTO
IPC: G11B5/00
Filed: 1989-10-19
Abstract: PURPOSE:To exactly test the friction of a tape by catching a change in the sliding state of the tape by the change of a friction coefficient obtained by using a friction and wear testing machine. CONSTITUTION:A loop-shaped video tape 1 is loaded to the friction and wear testing machine and set so that the read value of an incoming side tape tension sensor 5 can be 150g. Then, the loop-shaped video tape is driven and traveled at the speed of 1m/sec by the two pairs of capstans 2 and 11 and pinch rollers 3 and 12. The tape tension on incoming and outgoing sides is measured by the incoming side tape tension sensor 5 and an outgoing side tape tension sensor 9 and the friction and wear test of the loop-shaped video tape 1 is executed. Since the change of the friction coefficient due to this test is satisfactorily corresponding to the still property of a VTR, the change in the sliding state of the tape can be exactly caught by the change of the friction coefficient and the friction and wear of the tape 1 can be exactly tested without fail.

Abstract: PROBLEM TO BE SOLVED: To allow a means to inform of a worn battery to surely inform a user about it even in a noisy environment and to adopt a simple circuit to contribute to miniaturization and low cost of an equipment main body. SOLUTION: The mobile wireless equipment is provided with a voice reflection circuit 3 that reflects a voice signal from a transmitter 7 toward a receiver 8, a squelch circuit 4 that blocks a noise generated in a reception section 2 in a standby state so as not to be intruded to the receiver 8, and a voltage detection circuit 5 that monitors a voltage of a battery 6 and provides an output of control signals 101, 102 when the detected voltage is a prescribed reference value or below. The control signal 101 is used to control the squelch circuit to send a squelch noise intermittently to the receiver 8. The control signal 102 is a voltage signal and used to control the voice reflection circuit 3 to increase a level of a reflected voice (side tone).  The worn battery is informed by the intermittent squelch noise in the case of a standby state and by the side tone in the case of transmission in this way. Since the interruption period of the squelch noise is decreased and the side tone volume is increased in the progress of the worn-out state of the battery 6. Then the user can recognize a degree of the worn battery.

IPC: H05B6/24
Filed: 1987-10-29
Abstract: PURPOSE:To design synergistic improvement in heating effect by arranging a ferromagnetic body inside a coil to increase the heating effect on an object to be heated due to increased density of magnetic flux flowing through a crucible and making the heat of the ferromagnetic body also contribute to the temperature rise. CONSTITUTION:An object 3 to be heated of a paramagnetic body such as aluminum, copper, etc., is put into a crucible 1 embedded with a ferromagnetic body 2 such as iron, etc., and is heated by eddy current produced in the object 3 by applying current to a coil 5 wound around the crucible 1. Embedding the ferromagnetic body 2 such as iron, etc., in the crucible 1, the density of the magnetic flux passing through the crucible 1 increases and the heating efficiency of the object 3 increases. While the ferromagnetic body 2 is also heated by the eddy current, this also contributes to the temperature rise of the object 3. Constituting in this way, the heating effect is all the more improved.

Title: Spacer grid of nuclear fuel assembly
Inventor: CHIYAARUSU DEII MOOGAN
IPC: G21C3/352
Filed: 1993-11-02
Abstract: PURPOSE: To prevent a stirring blade from being broken in the assembling of a spacer grid and a fuel assembly by providing, on each metal plate constituting the grid, a projection piece forming the stirring blade which is extended from one edge of the metal plate. CONSTITUTION: A spacer grid 20 is formed of a metal plate 22 so as to form a cell for housing a nuclear fuel rod. Each metal plate 22 has a projection piece 30 extended from one edge thereof. Each projecting piece 30 is alternately bent so as to be extended to each side of the metal plate 22. The alternating arrangement of the projection piece 30 provides four projection part pieces per individual cell. The projection piece 30 is stayed in the vertical inner part to the whole sheath of the spacer grid 20. Therefore, the possibility of the projection piece being bent or broken at the time of assembly is reduced. In normal operation of a nuclear reactor, the projection piece 30 functions as a grid stirring blade for turning a coolant flow from the center of a passage to the clearance between rods situated in four corners of the individual cell.

Title: Built-in type cooker
Inventor: USUI KENZO
IPC: F24C15/08
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To correct warp or distortion of a top plate by fixing a reinforcing metal for preventing deformation to the rear surface of the top plate and providing the cooker body with a lever being fitted to the reinforcing metal through turning and stopping the top plate. SOLUTION: Reinforcing metals 9 are fixed to the opposite outsides of an opening 1b in the rear surface of a top plate 1 in the back/forth direction. A cooker body 2 is fixed with a rotary lever 10. The lever 10 is supported while being passed through a hole made in a lever base 11 and turns about the supporting part 10a. One end of the lever 10 is located below the reinforcing metal 9 as a stopping part 10c and fitted in a cut made in the reinforcing metal 9 at the time of turning thus stopping the top plate 1. Since the top plate 1 is stopped to the cooker body 2, adhesion between the outer circumferential part of the top plate and the upper surface of a drainboard can be enhanced. Consequently, warp or distortion of a top plate 1 can be corrected.

Title: Polymeric solid electrolyte and electrochemical device made by using it
Inventor: KUWABARA TSUNEO
IPC: H01G11/40
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To obtain a polymeric solid electrolyte having ionic conductivity and uniformity, and good adherence to a base material by using as the constituents a linear copolymer of vinylidene fluoride and chlorotrifluoroethylene, an electrolyte salt, a solvent, and a polymeric component with low degree of polymerization. SOLUTION: The copolymer of vinylidene fluoride (VDF) and chlorotrifluoroethylene (CTFE) realizes the reduction in the crystallizability of VDF by CTFE with almost no reduction in melting temperature and crystallization temperature to thereby serve to form a flexible solid electrolyte and improve the low-temperature characteristics. The VDF-CTFE copolymer preferably contains 5-50 mol.% CTFE and has an Mw of at least about 30,000. The copolymer is obtained by polymerizing VDF and CTFE by using a peroxide catalyst. An oligomeric component (e.g. a PVDF having a weight-average molecular weight of 300 to 5,000) may be added to the gel electrolyte. The use of the polymeric solid electrolyte can give an electrochemical device excellent in durability, shelf life and productivity.
