Title: Rotation positioning device
Inventor: TANGE KOJI
IPC: B62D5/083
Filed: 1989-10-26
Abstract: PURPOSE:To position a valve shaft in a neutral position with high precision by a method wherein correction is effected by a deviation from the natural position of the valve shaft determined from the rotation torque value of a torsion bar and a spring constant during a reference pressure. CONSTITUTION:A torsion bar 15 is first laterally twisted and rotated, a rotation angle and rotation torque required for rotation to the angle are determined, and from the values, the spring constant of the torsion bar 15 is automatically calculated. Thereafter, the torsion bar 15 is laterally twisted and rotated again and a rotation torque value when an oil pressure in an oil pressure passage is adjusted to e reference pressure is determined. By using the torque value and the already determined spring constant, a deviation single of the torsion bar 15 and a valve shaft 16 with a neutral position is calculated. The valve shaft 16 is rotated by an amount equivalent to the deviation angle to effect rotation positioning. This constitution positions the valve shaft 15 in a neutral position with high precision.

Filed: 1989-10-24
Abstract: PURPOSE:To discriminate the presence of a fault in a peripheral equipment and to obtain a system with excellent response by connecting a line generating a signal corresponding to the connection or the like of the peripheral equipment to a control unit. CONSTITUTION:When a cassette unit 3 is connected to a communication line 11 or a tape kind identifying line 13, a control unit 8 inputs an H level signal from a line 13, and when a DAT unit 4 is connected, the unit 8 inputs an L level signal from the line 13. The unit 8 discriminates whether the unit is 3 or 4 by detecting a signal level of the line 13. When a hand-free telephone set adaptor 5 is not connected to the communication line 12 and the identification line 14, the line 14 goes to an H level. Thus, the lines 11, 12 connected to the peripheral equipment are used when the communication is disabled, for the unit 8 to discriminate the fault of the peripheral equipment.

Abstract: PROBLEM TO BE SOLVED: To provide a polymer solid-state electrolyte having small internal resistance and a good preservation characteristic by using a gel electrolyte having good adhesiveness with respect to a current collector or an electrode. SOLUTION: The polymer contains a vinylidene fluoride copolymer as a principal chain and polyvinylidene fluoride as a side chain, the principal chain is made of rubber, the side chain is made of a crystal resin, and this polymer has resilience and a proper crystal property. When a gel electrolyte is formed with this polymer, electrolyte salt, and a solvent, a large quantity of the electrolyte salt and solvent can be contained in an amorphous portion, and high conductivity is obtained. The strong gel electrolyte is obtained due to a proper crystal portion. The gel electrolyte can be used in a wide temperature range, from a low temperature to a high temperature because it has good chemical resistance and a high melting point. Since this gel electrolyte has resilience, it is superior in adhesiveness to an electrode or a current collector, and its boundary resistance is reduced.
