Title: Electronic karaoke register
Inventor: NARUTOMI HANAKO
IPC: G10K15/04
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To provide KARAOKE terminal equipment with which the data of a music title register are registered in the music selection terminal equipment of a KARAOKE device and which is commanded while being retrieved with the title of a piece of music, singer or category. SOLUTION: This device is composed of an input keyboard 16, storage circuit 14, display circuit and infrared transmission circuit 15.

Title: Manufacture of tube for vehicular tire
Inventor: ONISHI MOTOJI
IPC: B29K21/00
Filed: 1986-05-14
Abstract: PURPOSE:To put a high performed tube to practical use by reducing its production cost by a method wherein both end parts of a tube main body which are cut by a heated cutter are hot-melted simultaneously with cutting and immediately fixed under pressure by abutting the melted cut surfaces against each other so as to restore the physical solid state property of the joint after cooling to that of the tube as before melting. CONSTITUTION:Both the end parts of a tube main body 6 are respectively held by holders 3 and 4. By shifting a heater 1 downwards, a cutter 2 cuts both the end parts of the tube main body 6 and simultaneously the cut surfaces are heated and melted. At this time, the space interval of the gap between the holders 3 and 4 and the share point of the cutter 2 becomes the length of the portion to be melted after cutting. Next, the cut-off pieces of the tube main body 6 are blown away by compressed air and the holders 3 and 4 are horizontally opened so as to separate the cut and melted surfaces of the tube main body 6 from the cutter 2. After that, the heater 1 is returned to its initial position and a supporting stand 5 is lowered. Finally, the left and right holders 3 and 4 are precisely abutted against each other so as to fix both the end parts by pressure.

SOLUTION: This rotor, divided in the circumferential direction into each magnetic pole, is provided with a laminated core 1 comprising electrical steel sheets stacked in the direction of a rotating shaft, and magnet parts 2 whose magnetic pole faces the magnetic pole surface and divides unit magnetic pole into one or more are provided. A given number of the laminated cores 1 are retained with pins 8, made of a member having low magnetic permeability, and inserted into holes 7 provided in the laminated cores via washers, and via protruding parts 4 and recessed parts 5 provided on the laminated cores 1. Then, the divided surfaces of the laminated cores are welded or bonded in the direction of the lamination.  This structure makes it possible to prevent the separation of the magnets to be caused by centrifugal force at the time of high-speed rotation, thereby improving the reliability of a motor. Also, the reduction of eddy current makes it possible to improve the motor efficiency. In addition, the segmentation of each magnetic pole unit does not require a processing with a large machine, which reduces the production cost of large capacity motors.

IPC: H01L21/52
Filed: 1981-07-17
Abstract: PURPOSE:To obtain a semiconductor substrate having a plane of excellent flatness and dimentional precision, by providing a thin W layer on the junction surface of an Mo substrate with a semiconductor element. CONSTITUTION:A thin W layer 7 is prepared, by a chemical evaporation method, on the junction surface 6 of an Mo substrate 5 made by powder metallurgy, with an Si element 1. Evaporation is performed in such a manner that the Mo substrate is put in a reaction tube and a vaporized W compound, such as WCl6, and a carrier gas, such as H2, are introduced thereinto at a constant temperature of 800 deg.C. The thickness of the thin W layer is controlled by the density of the vaporized W compound which is introduced, the temperature of a reaction furnace, the pressure of a mixed gas and a time required for reaction. Since the thin W layer thus prepared is resistive substantially to the effect of oxidation by an outside atmosphere and that of corrosion by a treatment with an acid, the junction surface thereof with the element turns to be of high smoothness both in terms of planeness and dimentional precision, and the property thereof is stable when it is used in junction with the semiconductor element.
