Title: Platinum alloy for accessory
Inventor: TAMEMASA HIROSHI
IPC: C22C5/04
Filed: 1983-02-16
Abstract: PURPOSE:To obtain a Pt alloy for accessories with superior mechanical strength and castability as well as superior workability by adding specified amounts of Ga and Cu to Pt as a principal component. CONSTITUTION:The composition of a Pt alloy used as a material for a ring, a necklace, a brooch, a tiepin, cuff links, etc. is composed of 84-96wt% Pt, 1- 10wt% Ga and the balance Cu. The reason for the addition of Ga is that Ga improves the mechanical strength and castability while satisfying the requirements that the reaction with a casting mold must be inhibited during casting and that the concn. of oxygen can be controlled during casting. When the Ga content exceeds 10wt%, the workability is remarkably deteriorated. The reason for the addition of Cu is that Cu further improves the mechanical strength by hardening.

Abstract: PURPOSE:To eliminate the need for a monitoring transmission circuit and a data buffer and to miniaturize the circuit scale by inserting a monitoring reception circuit generating the output signal of a TTL level in series with a current loop and giving a low impedance to the monitoring reception circuit so as to maintain the current loop communication. CONSTITUTION:A monitoring reception circuit 31 is inserted in series with a current loop 10, the monitoring reception circuit 31 generates an output signal of a TTL level and has a low impedance to maintain the current loop communication. The monitoring reception circuit 31 is inserted in series with the current loop 10 to decrease a current loop current but since the impedance of the monitoring reception circuit 31 is low enough to maintain the current loop communication, no effect is given on the TTL level output of a conventional communication reception circuit 21 and the monitoring output signal of a TTL level is obtained by having only to add the monitoring reception circuit. Thus, the circuit scale is miniaturized.
