Title: Centrifugal casting method
Inventor: NAKAISHI MASAO
IPC: B22D13/10
Filed: 1979-05-31
Abstract: PURPOSE: To assure the evenness of inside and outside material quality by forcefully cooling the inside surface side by cooling gas from right after pouring up till freezing.  
     CONSTITUTION: Molten metal is poured into a rotary metal mold 1 for centrifugal casting. From right after the pouring of the molten metal until the molten metal freezes as casting, the force cooling of both sides in the casting is done by inserting a cooling gas flow pipe 5 from the opening side of the metal mold 1 and spouting cooling gas 6 toward the inside surface of the molten metal layer being formed as a casting from the jet hole 5a group of the blow pipe 5. Compressed air is advantageous as the cooling gas 6 in terms of cost, but for higher cooling effect, it is effective to use gas of particularly lowered temperature such as, for example, upper filling gas of liquefied nitrogen.

Abstract: PURPOSE:To contrive an improvement in dispersibility of a filler fiber and metallic fiber in a molded body, by a method wherein the metallic fiber and filler fiber are mixed into synthetic resin at a desired rate, which is used by cutting into a state of pellets. CONSTITUTION:A filler fiber 1 and metallic fiber 2 are inserted into a die of an extruding machine at a desired rate, into which molten resin is infiltrated and cut into necessary lengths, through which pellets 4 are manufactured. With this construction, an element constituting a molding material becomes of only one kind of the pellets obtained by mixing base plastic 3, the filler fiber 1 and the metallic fiber 2 with one another together. Therefore, the title material becomes a state where the metallic fiber 2 is dispersed already favorably throughout the molding material as compared with a conventional material where the inside of pellets mixed the filler fiber are dotted unequally with pellets mixed with the metallic fiber. Therefore, since intertwining among the metallic fibers 2 becomes strong, conductivity and a shielding effect of an electromagnetic wave of a molded body are stabilized and improved.

Title: Vehicular air-conditioner with cold blast preventing function
Inventor: YAMASHITA YUTAKA
IPC: B60H1/12
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a vehicular air-conditioner with a cold blast preventing function, capable of securing a sufficient blasting effect even in such a case where a temperature rise in engine cooling water is not enough. SOLUTION: A blast upper limit BL is regulated according to a current temperature of engine cooling water, while a current temperature in this cooling water is always monitored by a water temperature sensor, thereby comparing its sizing relationship with the engine cooling water temperature measured at the last time. Insofar as in the case where such a state that the current temperature will not become a larger value than the previous one is continued more than the setting time, the value of this upper limit BL regulating the blast quantity is gradually increasing according to the elapse of time. Since the sufficient blast quantity is securable even in the case where a temperature rise in the engine cooling water is stagnated, the heating of a large air quantity can be done even in the case of traveling or the like in a cold district.
