Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/716
Filed: 1987-08-31
Abstract: PURPOSE:To provide a magnetic recording medium which averts spacing loss and is imparted with durability by disposing two kinds of fine particles having different diameters on a thin ferromagnetic metallic film and disposing a thin ferromagnetic metallic film thereon. CONSTITUTION:The thin ferromagnetic metallic film 2 is formed by an electron beam vapor deposition method, high-frequency sputtering method, etc., on a high-polymer film 1 and two kinds of the fine particles 3, 4 having the diameters d1 and d2 (where d1<d2) are disposed thereon. The thin ferromagnetic metallic film 5 is further disposed thereon and is so constituted that the tips of the fine particles 3 having the diameter d2 are exposed from the thin ferromagnetic metallic film 5. Since the exposed fine particles 3 slide mainly with a mating side, the durability is improved and in addition, the thin ferromagnetic metallic film 5 itself has the projections by the fine particles and, therefore, the durability is maintained even if the exposed height is not so much increased. The spacing loss is decreased and the degradation in C/N in the short wavelength range is obviated.

Abstract: PURPOSE: To improve the sealing relation between a bearing ring and a spindle so that a larger volume of compressed air can be supplied to a receptacle to purge it, by loading annular seals in a second and a third annular groove with compressed air applied radially from the side opposite to the spindle. CONSTITUTION: A compressed-air duct 30 is defined through a spatially fixed bearing ring 12 in a spindle stock 11 down to a region between two annular seals 42 and 43. When this compressed-air duct 30 is loaded with compressed air in the stationary condition of a spindle 13, these two annular seals 42 and 43 deform outward and separate from each other axially by the air pressure and are put into butt contact with the radial front of annular grooves 40 and 41 formed around the spindle 13.

Title: Metal-resin composite body
Inventor: KAWANISHI TOSHIAKI
IPC: G01K7/16
Filed: 1991-08-02
Abstract: PURPOSE:To enable diffused metal particles to make contact with one another at low resistance and eliminate dispersion of characteristics by sandwiching a metal sheet between thermally plastic resin sheets wherein the metal sheet has lower melting point than the resin sheets, and applying supersonic wave vibration to the laminated body to give a metal.resin composite body. CONSTITUTION:A metal sheet is put between thermally plastic resin 1 wherein the metal sheet has lower melting point than the resin, both are brought into contact by pressure, supresonic wave vibration is then applied to the laminated body to melt and fractionate the metal sheet and also to soften the resin 1 and thus the fractionate particles are dispersed and mixed in the softened resin and a metal.resin composite body is manufactured. The dispersion and mixture is carried out due to the supersonic wave energy with which the metal sheet is melted and the resin sheets are heated and softened and due to the accelerating force difference based on the difference of their specific gravities and at that time it is necessary that the resin is softened but not melted. Since the vibration is transmitted to the metal sheet through the resin sheets, sufficient contact pressure between the metal sheet and the resin is necessary.

Title: Audio transmission television receiver and exclusive receiver
Inventor: WATANABE HARUO
IPC: H04N5/00
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To allow even a person who is hard of hearing to view a program under the condition as persons with usual audible capability without increasing a sound volume by incorporating an audio transmission function to a television receiver side, allowing the exclusive receiver to receive a transmitted radio wave and allowing the person who is hard of hearing to hear the sound by means of a receiver. SOLUTION: A television reception section 7 separates a received radio wave into a video signal and an audio signal and gives only the audio signal to a television audio amplifier 8 and an audio signal transmission section 9. The audio signal transmission section 9 sends the audio signal to a radio reception section 10 of an exclusive receiver by means of a radio wave. An amplifier section 11 controls the level of the audio signal from the radio wave received by the radio reception section 10 and provides an output of the result to a receiver 5.  Since the sound volume from a speaker will not be higher more than a required level, a person who is hard of hearing can enjoy a TV program with persons with normal audible capability, without troubling surrounding persons and enjoys video and audio signals, even when moving to a place apart from the television receiver if it is located within a radio wave reach.
