Title: Production of abrasion-resistant sintered alloy
Inventor: SUZUKI NAOHIRO
IPC: B22F5/00
Filed: 1978-12-26
Abstract: PURPOSE: To improve the dimensional accuracy and strength of a Cu-Sn sintered sliding material which uses MoS 2  as a solid lubricating material by coating Cu on the surface of MoS 2  powder and using in producing said sliding material.  
     CONSTITUTION: In producing the sliding material by molding and sintering Cu-Sn alloy powder, MoS 2  powder is mixed as a solid lubricating material. In this case, Cu is coated on the surface of the MoS 2  powder by an electrochemical method and this Cu-coated MoS 2  is mixed in Cu-Sn powder and the mixture is molded and sintered to produce the sliding material. The dimensional change at the singtering of the molding becomes neasrly the same as that of the molding not added with MoS 2 . The molding thus obtained is extremely high in dimensional accuracy and does not require any sizing process. As compared to the case in which MoS 2  is added alone, there is practically no decrease in the strength of the sintered sliding material.

Title: Copying machine
Inventor: HASHIMOTO KENJI
IPC: G03G15/20
Filed: 1981-10-07
Abstract: PURPOSE:To make holding during warming-up unnecessary to improve the copy work efficiency, by providing a print switch reserving mechanism where the depression operation of a print switch is stored during warming-up. CONSTITUTION:If a print switch 6 is operated when an output S1 of a temperature detecting circuit 5 is low-level and a copying machine is in course of warming-up, an FF 18 is set through an AND gate 17 which is opened by the inverted output of the output S1 passing an inevrter 13. Then, the switch 6 is reserved, and it is stored in the FF 18. The set output of this FF 18 becomes a print signal through an AND gate 19 which is opened by the inversion of the signal S1 to the high level at the end of warming-up when a fixing temperature reaches a prescribed value. Consequently, holding during warming-up is unnecessary, and the print is started simultaneously with the end of warming-up if the print switch is operated during warming-up, and thus, the copy work efficiency is improved.
