Title: Power supply starting/stopping circuit
Inventor: MIYAZAKI TAKAHIRO
IPC: H02J3/38
Filed: 1990-08-31
Abstract: PURPOSE:To operate N other power supplies continuously upon interruption of one power supply by providing a starting signal to each power supply after passing it through a plurality of power supply loop circuits sequentially in series. CONSTITUTION:Upon interruption of a power supply #1 due to a trouble, the power supply #1 interrupts a normal operation signal to be fed from an alarm circuit 13 and produces an alarm signal at terminal So. Consequently, signal supply from an AND circuit 15 is interrupted and a starting circuit 16 disables a power supply circuit 11. Other sound power supplies #2-#4 receive alarm signals from the faulty power supply #1 through terminals Si, but no alarm signal is outputted from the alarm circuit 13 because the power supply is operating normally. Consequently, an AND circuit 14 does not produce an output and terminals A and B in a loop circuit 12 are kept in closed state. The AND circuit 15 outputs signals continuously thus producing output from each power supply circuit 11 continuously.

Filed: 1987-09-11
Abstract: PURPOSE: To weld a seam without overheating optical fibers by welding the seam of a tube with laser light. CONSTITUTION: A metallic strip 11 is received and is continuously formed into a partially closed tube 12 which has a gap in the longitudinal direction in the top part. A guide means of optical fibers 13 continuously receives optical fibers 13 and guides them through the gap in the longitudinal direction of the top part of the tube 12 so as to lay them in the tube 12. Both ends of the steel strip 11 are brought into contact with each other along the seam in the top part of the tube 12 to form the completely closed tube 12. That is, the luminous flux of laser light is focused on the surface of the seam to conductively weld the seam without filler metal. Thus, an optical fiber cable covered with the hermetically sealed homogeneous metallic tube 11 is continuously produced.
