Title: Production of carbon-metal composite material
Inventor: KANO MASATO
IPC: C04B35/52
Filed: 1990-03-05
Abstract: PURPOSE:To obtain the carbon-metal composite material having high density and strength by controlling the maximum temp. at the outlet of an extrusion die above the solidifying temp. of a binder pitch to be added to the raw material when the molding material contg. a carbonaceous aggregate and a metallic fiber is extrusion-molded and sintered. CONSTITUTION:A binder pitch is added to the aggregate obtained by mixing a fibrous or woolly metallic fiber consisting of a carbonaceous and graphitic powder and a carbon fiber and kneaded to obtain the raw material which is extrusion-molded. In this extrusion process, the maximum temp. at the outlet of the extrusion die is controlled above the solidifying temp. of the binder pitch, and then the molded body is sintered. By this method, the density of the molded body at the die outlet is increased, and the volatile matter content of the binder pitch is reduced to <=30%. As a result, the amt. of the gaseous decomposition product is decreased, the expansion and increase in porosity of the molded body being burned are controlled, and a carbon-metal composite material having high density and strength which is not obtained by the conventional extrusion molding of a carbon material is produced with high productivity.

Inventor: MATSUNO ROKUZO
IPC: B21D28/24
Filed: 1988-03-09
Abstract: PURPOSE:To perform the working of piercing, etc., without deforming the metallic member by providing a space at the lower surface of the part of the metallic member to be worked and continuing the pressing of a press member flowing an electric current between the working press member and the metallic member.

Title: Time monitoring system
Inventor: IWATA KATSUYUKI
IPC: G06F11/30
Filed: 1983-03-31
Abstract: PURPOSE:To efficiently perform fault processing, by commonly using one timer counter for monitoring the time of each hierarchy. CONSTITUTION:A timer counter 10 acts as a monitoring time generating section for monitoring the operating condition of hierarchies 1'-2'. Namely, in the course of monitoring the operation in a channel controlling section 7 at the highest rank, control by an access request is transmitted from a storage controlling unit 3 to a main memory 1 through a main memory controlling section 2, and therefore, the operation monitoring time T3 at the channel controlling section 7 is the longest. On the contrary, the operation monitoring time T1 for the hierarchy 1' at the main memory controlling section 2 is the shortest. Therefore, the outputs of bit 1, bit 3, and bit 5 of the timer counter 10 are used for the operating time monitoring of the hierarchy 1', hierarchy 2', and hierarchy 3', respectively. These bit outputs are fetched after their rises are differentiated by differentiating circuits 11-13.
