Filed: 1988-04-04
Abstract: PURPOSE:To improve the joining power of a cast-in metal and fiber reinforcing metal composite material by casting in the fiber reinforcing metal composite material through the zinc alloy contg. a copper or an Al at specified rate respectively. CONSTITUTION:In case of casting-in fiber reinforcing metal composite material (FRM) 2 and cast-in metal, the zinc alloy contg. 0.1-10wt.% copper or that contg. 1-5% Al is coated on the surface of the FRM 2 by a galvanizing method, etc., to execute cast-in. The metal of a Li, Na, etc., is added at the rate of 0.01-5% in the zinc alloy, if necessary. This zinc alloy is difficult to be oxidized its viscosity at melting time is large and its temp. zone is wide, hence it is easily alloyed with the matrix metal of the FRM 2 and cast-in metal main body. The joining power of the FRM 2 and cast-in metal main body 1 is thus improved.

Abstract: PURPOSE:To open again a communication channel when a voltage is recovered by backing up also a control circuit for transmission and reception by a power supply which backs up a RAM for data in case the level of the voltage supplied from a battery is reduced. CONSTITUTION:A detecting circuit 55 detects that the voltage of a battery 51 is reduced less than a prescribed level and an interruption is applied to a CPU 31 by a detecting signal Sd. Then an interruption routine is executed by the CPU 31. In the routine all data needed to open again the present communication channel are saved at a RAM 41 and the transmission of a transmission circuit 24 is stopped. Then the port output Pa is set at H and transistors TR Q2 and Q1 are turned on. The voltage of a battery 42 is supplied to circuits 31-35 and the RAM 41 respectively. Both a microcomputer 30 and the RAM 41 are backed up by the battery 42. Thus the communication channel can be opened again correctly when the battery voltage is recovered.
