Title: Operating method of sewage pump
Inventor: TANABE SEIICHI
IPC: C02F1/00
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To hold sludge concentration to prescribed concentration when drain of sewage is started by driving a sewage pump installed on a bottom part of a sewage tank in a reverse direction for a constant time before the sewage pump is driven in normal, agitating sludge deposited on a bottom part of the sewage tank, and then draining sewage water by switching into driving of normal rotation. SOLUTION: A sewage pump 2 is driven in a reverse direction for a constant time before the sewage pump 2 is driven in a normal direction for draining sewage water in a sewage tank 1. Namely, sewage water stored in a drain pipe 3 flows (makes reverse flow) into the sewage tank 1, and sludge deposited on a bottom part of the sewage tank 1 is agitated. After deposited sludge is uniformly dispersed in sewage water, the sewage pump 2 is switched in the normal driving. Sludge concentration is held to a prescribed concentration especially when drain of sewage water is started. In this time, existence of sewage water in the drain pipe 3 is detected by a sensor 6, reverse driving of the sewage pump 2 is stopped when sewage water in the drain pipe 3 is eliminated, and thereby, racing and failure of the sewage pump 2 are prevented.

Title: Method for cooling printing frame
Inventor: YAZAKI YOSHIO
IPC: H01L21/027
Filed: 1988-11-25
Abstract: PURPOSE:To uniformly cool a mask film so that the mask film can be regulated to and maintained at an adequate temp. by passing flowing water which absorbs heat rays and allows the transmission of UV rays in the intermediate position between a light source and the printing frame. CONSTITUTION:A work 7 held in tight contact with the mask film 6 crimped between an upper frame 4 and a lower frame 5 of the printing frame is irradiated by the light source 2 of an exposing device. A water tank 9 for cooling which absorbs the heat rays and allows the transmission of the UV rays is provided in the intermediate position between the light source 2 and the printing frame 4 and the flowing water is passed in this position. The heat rays contained in the irradiation light are, therefore, absorbed at the time when the irradiating light from the light source 2 arrives at the mask film 6. The temp. rise of the mask film 6 is prevented in this way and the adequate patterns are printed on the work 7.
