Title: Redundant pump switching system
Inventor: TAKEUCHI KIYOSHI
IPC: F04D15/00
Filed: 1990-11-19
Abstract: PURPOSE:To shorten the stop of supplying a cooling liquid by starting one pump during the operation of the other pump and stopping one pump after a fixed period of time since the other pump enters the steady operation in a system where pumps connected parallel to each other to be redundant are periodically switched. CONSTITUTION:When it becomes switching timing, it is judged whether a pump 11 is during operation or not from a value of a register 22, and if yes, a pump 12 is started, is on standby during T2 seconds (one second, for example) and then the pump 11 is stopped. If the pump 11 is not during operation, the pump 12 is started, is on standby for T2 seconds, and then the pump 12 is stopped. At this time, it is judged whether a flow rate switch 16 is off or not. If yes, it is judged from a value of the register 22 whether the pump 11 is during operation or not. If the pump 11 is during operation, it shows that the pump 11 gets out of order and the flow rate switch becomes off, so that the pump 11 is stopped and the pump 12 is started. On the other hand, if the pump 11 is not during operation, it shows that the pump 12 during operation gets out of order, so that the pump 12 is stopped, and the pump 11 is started.

Title: Pasting board
Inventor: TAKE ISAO
IPC: G09F15/00
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To paste a subject to be pasted, each as a poster, to a pasting surface without leaving air between them by making the surface resisting to attaching of dirt. SOLUTION: A fluororesin layer 14 is formed on the surface, and the surface of the fluororesin layer 14, i.e., a pasting surface 12, is made uneven by creping in order to allow air between the surface and a pasted material to escape. Since air escapes from recesses in this uneven part, no air is allowed to remain, preventing the pasted material from degrading in appearance as it swells with air that might otherwise remain. The fluororesin layer 14 on the surface resists adhesion of dirt, and even if dirt adheres to the surface, it can be removed relatively easily, so the surface can be used cleanly over a long period.
