IPC: F16F9/32
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent a piston ring from being pressed against an inner wall of a cylinder even when pressure is applied to the inner surface side, and to prevent increase of frictional force between the piston ring and the cylinder inner wall by forming circular grooves on an outer peripheral surface of the ring along its circumferential direction, and arranging communication means for communicating the grooves with a ring inner peripheral surface. SOLUTION: A piston ring 28 is composed of a cylindrical endless ring formed with annular pressure introducing grooves 32 along its circumferential direction, on its outer peripheral surface 28a. Two grooves 32 are continuously formed over the circumference of the outer peripheral surface 28a of the ring, with a spacing therebetween in an axial direction of the ring 28. Through-holes 33 are formed on the piston ring 28, for communicating the grooves 32 out the outer peripheral surface 28a with an inner peripheral surface 28b. A groove 30 is formed on the bottom of a strip-like groove 29 on a back surface center portion of the piston ring 28, while an O ring 31 is fitted to the groove 30. The through-holes 33 are formed on the piston ring 28, on respectively its upper and lower sides of the O ring 31.

Title: Superconducting coil
Inventor: OTSUKA SHOZO
IPC: H01F6/06
Filed: 1986-09-12
Abstract: PURPOSE:To make a title device small-sized and lightweight by dividing a multilayered coil into at least two blocks, and the cross-sectional area of the strand of a superconducting wire of each block is serially made small on a block by block basis toward the outer periphery side. CONSTITUTION:An inner bath 4 of a superconducting coil has a track-shaped profile, and a superconducting coil 5 comprises an inner periphery side block 5B1 and an outer periphery side block 5B2. The inner periphery side block 5B1 is constructed by winding a strand having a same cross-sectional area S1, for instance, in three layers in the radial direction and in nine layers in the axial direction. Also, the outer periphery side block 5B2 is constructed by winding a strand having a same cross-sectional area S2(<S1), for instance, in four layers in the radial direction and in nine layers in the axial direction. Thus, in the superconducting coil 5, due to the magnetic flux density distribution characteristics, the cross-sectional area of the superconducting wire strand constituting each block can be serially made small toward the outer periphery side. Therefore, as compared with a superconducting coil having the same performance in which the cross-sectional area of the strand is uniform, it can be made small-sized and lightweight.

Title: Thin high-polymer film element having high photoresponsiveness and its production
Inventor: UENO TOSHIHIKO
IPC: G09F9/30
Filed: 1985-09-27
Abstract: PURPOSE:To improve resolving power and repetitive characteristic by constituting a titled element in such a manner as to include a light absorptive layer between a pair of substrates and to incorporate a light absorbent into a high- temp. ion conductive material. CONSTITUTION:The conductivity of the high-temp. ion conductive material is low at a room temp. and therefore, even if a voltage is impressed between a pair of electrodes 5, ions can hardly enter the inside of a thin high-polymer film 3 and the color change does not arise in the thin high-polymer film. The ion conductive layer 4 in the heated part attains a high temp. state when said layer is locally heated by the irradiation of light such as laser; therefore, the conductivity of the ion conductive layer is extremely low and the extremely fast ion transfer into the thin high-polymer film 3 is possible. The color change arises only the part subjected to the irradiation of the light when the voltage is impressed to the electrodes 2 of the substrate 1. The irradiated part is quickly cooled when the irradiation of the light is stopped. The color change state is, therefore, held as it is to attain the memory state. The resolving power and repetitive characteristic are thereby improved.

Abstract: PROBLEM TO BE SOLVED: To prevent angle setting errors, undesirable function in response or the like, by digital-displaying the synchro angle of at least a simulating synchro transmitter on an angle display part. SOLUTION: In a digital-synchro simulating device, when a power switch 1 is turned on, a power supply 12 operates, a display lamp 9 turns on, and respective parts of this device become operative. When a display selection switch 7 is switched to the receiver side, a synchro angle expressed as a relation between a three-phase input signal connected to the three-phase switch of a synchro input part 10 and a reference single-phase AC signal connected to a single-phase input terminal, is converted into a 16-bit digital signal by a synchro/digital converter 13, which is transmitted to an angle display part 8 through a data selector 14 to be displayed. When the display selection switch 7 is switched to the transmitter side, the angle display part 8 displays the transmitted synchro angle of a digital/synchro transmitter part.

Title: Manufacture of field effect semiconductor device
Inventor: KOSEMURA KINSHIRO
IPC: H01L29/812
Filed: 1984-10-17
Abstract: PURPOSE:To remarkably improve the production yield by a method wherein a semiconductor device is discarded when judged to be unacceptable after examination of its saturated drain current characteristics. CONSTITUTION:A voltage is applied across a source electrode 4 and drain electrode 5 for the application of a saturation drain current. The value of the saturation drain current with a recess 8 already in existence depends on the design of the field effect semiconductor device. The saturation drain current is measured to decide if a specimen device is acceptable. A non-saturation feature means a current leaking mainly into a buffer zone 2 and the involved device is discarded. By this, field effect semiconductor devices of excellent performance characteristics only may be produced, at a high yield.
