Patent JP-H03245745-A (JP)
Title: Potor
Inventor: SANADA TETSUJI
IPC: H02K1/02
Filed: 1990-02-22
Abstract: PURPOSE:To obtain sufficient strength and high efficiency for high speed rotation of a rotor by using a high strength rotor core where an oxide film is formed on an ultrahigh strength steel of a soft magnetic material. CONSTITUTION:The profile of a rotor core 12 is formed substantially annular, and a shaft 14 is press-fitted in its inner hole 12a. Particularly, the core 12 is manufactured by punching a maraging steel plate, and an insulating oxide film 12c is formed on the surface. Thus, the maraging steel formed in a thin plate in this manner has iron loss characteristic. If the rotor 10 is rotated at a high speed, i.e., when the frequency is high, the iron loss is lower than that of a silicon steel plate of a general rotor material, and a motor of high efficiency can be realized. Thus, magnetic properties required for the core 12 are satisfied, and mechanical strength of the core 12 itself can be improved.

Title: Manufacture of resin mould connection of cable
Inventor: HIGURE KEIICHI
IPC: H01R43/00
Filed: 1990-02-22
Abstract: PURPOSE:To disperse the moisture and residual leftovers sufficiently by cooling gradually the outer surface of a resin after moulding by placing it in a heated and dried inert gas ambiance, and at the same time, setting the temperature of the inert gas higher than the temperature of the contact surface between the above resin and the center conductor of a cable constantly. CONSTITUTION:The temperature To at which an inert gas is heated in a heating device 13 is set responding to the temperature property of the temperature Tc of the contact surface between a resin and a conductor. And the temperature To is set a little higher than the temperature Tc constantly. As a result, the temperature To near the outer surface of a mould layer 5 is lowered gradually with the time while maintaining an equal temperature difference with the Tc. And since the inert gas heated to a specific value is delivered into a container 6 by a constant control, a plenty of blowing can be made. Consequently, the moisture and the residual leftovers generated in a bridging can be dispersed sufficiently.
