Title: Magnetic tape device
Inventor: SAITO FUMINARI
IPC: G11B15/665
Filed: 1987-05-19
Abstract: PURPOSE:To surely switch the operating mode at a light load by preventing a reaction caused to in an elastic member from being transmitted to a rotary body in pressing and fixing a magnetic tape unloading means to a 2nd position. CONSTITUTION:A lock means locking a drive means when a magnetic tape unloading means 182, 183 are pressed to the 2nd position is provided and a reaction generated in the elastic member is not transmitted to the rotary body when the lock means is fixed to the 2nd position.

Title: Contact installed in electrical machinery and apparatus
Inventor: KORIYAMA TETSUO
IPC: H01H1/04
Filed: 1992-05-15
Abstract: PURPOSE:To provide a contact installed in an electrical machinery and apparatus, manufactured by such a method that even if plating is given to the whole surface of a contact material, the resultant contact can be prevented from oxidation and sulfuration thereof and also the cost of plating given to the whole surface of the contact material can be controlled lest the cost should become considerably high over that of plating given partially to the surface of the contact material. CONSTITUTION:A contact installed in an electrical machinery and apparatus comprises a double plating layer formed on the whole surface of a contact material which has an Ag contact-point 2 joined to a contact-point base 1. A first plating layer 5 is made of Ag, and a Pd film forming a second plating layer 6 is formed further on the surface of the first plating layer 5 so that a part of the first plating layer 5(Ag) can be replaced by the Pd film. The Pd film is excellent both in oxidation resistance and sulfuration resistance, and therefore not only the oxidation of the contact-point base 1 can be naturally prevented but also the oxidation and sulfuration of the whole of the contact can be prevented even under any environmental condition offered to the contact by covering the imperfection that the formation of only the Ag-plated layer on the contact material causes sulfuration and subsequent discoloration in the resultant contact. Besides, such a case of plating given to the whole surface of the contact material like this results in very large cost reduction over cost for the case where Sn or the like plating is partially given to the surface of the contact material.
