IPC: H01B17/42
Filed: 1994-11-29
Abstract: PURPOSE: To enhance the discharge starting voltage at dirt to suppress the corona discharge on a porcelain tube surface by minimizing the potential inclination of creeping electric field of a porcelain tube bushing with an earth metal fitting. CONSTITUTION: An earth metal fitting 17 is connected to a case 1 together with a pressing metal fitting 8 by a bolt 11 and a nut 12 to be set in earth level, and an earth electrode is formed to mask the metal fitting 8. Thus, the space of an equipotential surface curve (b) is the narrowest in the top end part of the metal fitting 17 in the atmosphere, and extended on a porcelain tube 4 surface including a flange 6.  Therefore, the potential gradient of creeping electric field of a bushing 2 such as the flange 6 surface part is lowered, the discharge starting voltage at dirt is increased, and no corona discharge is generated on the surface of the porcelain tube 4 of the bushing 2 even when the whole body of the bushing 2 including the flange 6 is downsized to shorten the distance with the internal conductor 3 of the metal fitting 8, and the generation of radio noise or wear of the insulator 4 by corona discharge is never caused.

Abstract: PURPOSE:To constitute a high speed transmission circuit on the upper surface of an opening part and a delay circuit on the parts except of the opening part by rendering an insulating layer except of the opening part higher in its dielectric constant than an insulating layer in the opening part constituted of only fluorocarbon resin in a metal plated laminate board. CONSTITUTION:In the part of an opening part 5, the dielectric constant is small because the insulating layer is made of only welding fluorocarbon resin 3, and a circuit provided on the opening part 5 is used for high speed transmission, and since the insulating layer in the parts except of the opening part 5 is synthesized with a base film 2 having a large dielectric constant or woven fabrics and the welding fluorocarbon resin 3 having a small dielectric constant, the dielectric constant is relatively large, and the circuit provided on the part is used as a delay circuit. As metallic foil 1, rolled copper foil of 35mum is utilized, in which the adhering surface faced to the side of a base film 2 is roughened by a sand mat process and as the base film 2, a polyimide resin film having high heat resisting property and being 50mum in its thickness is employed. Furthermore, as the welding fluorocarbon resin 3, there is used tetrafluoroethylene- hexafluoropropylene copolymeric resin having heat welding property of being 50mum in its thickness.

Abstract: PURPOSE:To simplify the structure of a motor-operated power steering device by obtaining a clutch to be automatically in with such a constitution that when an input shaft is rotated and its rotational torque exceeds the set torque of a torsion bar, a coil spring is enlarged in its diameter through a pressing part. CONSTITUTION:A steering handle 30 is rotatively operated so as to rotate an input shaft 11, and when its steering force exceeds the set torque of a torsion bar 24, the torsion bar 24 is largely twisted so that a clearance A in the rotational direction disappears, and a square hole 21 becomes engaged with a rectangular shaft 22 so that the steering force is transmitted to a wheel from the input shaft 11 through the rectangular shaft 22, an output shaft 12, a pinion shaft 33, a pinion 32 and a rack 37. In addition, a fork 19 rotated together with the input shaft 11 pushed an engagement piece located at the front side in the rotational direction of the fork 19 in the peripheral direction, and a coil spring is thereby enlarged in its diameter and pressed to an outer wheel 13 so as to obtain a clutch connecting state. In this state, the driving force of a motor 35 can be transmitted to the output shaft 12 as steering auxiliary force from the outer wheel 13 through the coil spring 16.

Abstract: PURPOSE:To have an image of high quality always stably by installing a structure, which consists of insulative material and is to couple two rings, penetratively at the ends of each wire cathode, and by installing an insulated wire between the wire cathodes and the junction of these two rings penetrative while located vertically to the wire cathodes. CONSTITUTION:Wire cathodes 30(i) thru 30(iv) are stretched and given a tension by a spring 35, and penetrate holes in two rings of W-rings 31(i) thru 31(iv). An insulated wire 32 is installed between the junctions 37(i) thru 37(iv) of these W-rings and the wire cathodes 30(i) thru 30(iv) while taking vertical positioning to the wire cathodes. Even in the case vibration is generated on the wire cathodes 30(i) thru 30(iv) by any external force applied to an image display device concerned, the W-rings 31(i) thru 31(iv) promptly absorb the vibratory energy, i.e., serve as a damper, to stop the vibration of the wire cathodes 30(i) thru 30(iv). Thereby high quality image can be obtained stably.
