Title: Switching mechanism for web processing equipment
Inventor: NAKAMURA FUMIHIKO
IPC: G03G15/00
Filed: 1988-12-29
Abstract: PURPOSE:To control the extent of power consumption by detecting the opening or closing of a cover body installed in a proper spot of a box body internally provided with web processing equipment, and making such a power supply as capable of processing operation so as to be done only when a power switch is in an on-state and the cover body is in a state of being opened. CONSTITUTION:Power supply for all parts 31, 32 and 36 is stopped even if a power switch 35 is turned on, whereby all but a memory part of a control processing unit 30 come to an off-state. When a fact that a cover body is opened is detected by a microswitch 34, the power supply for each part is started and web processing equipment starts its operation. On the other hand, when this cover body is closed during operation, or operation is stopped by paper termination and this state continues as long as 10 minutes, processing operation is regarded as being finished, the power supply for each part is stopped even if the power switch is kept in the on-state intact. Thus, if the power switch is turned on, the power supply necessary for the operation is not carried out unless the cover body is opened, and that even if the power switch is omitted to be turned off, wasteful power is not consumed when the cover body is closed.

Title: Hydraulic turbine driving pump
Inventor: NISHIMURA KOICHI
IPC: F04D13/04
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent entanglement of a commonly using drain pipe in performing drain operation by a plurality of units by directing water delivered from a induced port in the same direction as a delivery port of a pump by turning the induced port of a hydraulic turbine toward the pump side. SOLUTION: The inside of a pump casing 7 is formed as a structure for merging delivery water W1 delivered from a induced port 5 of a turbine 1 with delivery water W2 of a pump. Thus, the delivery water W1 of the turbine delivered from the induced port 5 can be drained by being accompanied by the delivery water W2 of the pump by a commonly using drain pipe 16 by simple connecting work for connecting the commonly using drain pipe 16 to a delivery port 7C of a pump casing 7. Thus, when performing drain operation by inputting a plurality of hydraulic turbine driving pumps in an area to be drained, orderly laying work can be easily performed without entangling the commonly using drain pipe 16 with every hydraulic turbine driving pump with a commonly using drain pipe 6 of the other hydraulic turbine driving pump.
