Patent JP-H02278824-A (JP)
Title: Wet etching apparatus
Inventor: YAMADA OSAMU
IPC: H01L21/306
Filed: 1989-04-20
Abstract: PURPOSE:To uniformly execute a selective etching operation inside a face of a substrate irrespective of whether a mask pattern exists or not by a method wherein the substrate to be etched is supported in parallel with a liquid level and its support body is turned by a rotation movement which is turned in parallel with the liquid level around the center of the substrate and by a revolution movement around the center of a liquid tank. CONSTITUTION:A substrate support body 1 is immersed in an etching liquid in parallel with a liquid level inside an etching-liquid tank 4. A rotation movement of a rotation axis 3 is transmitted via gears 61, 31 from a shaft 6 of a motor 5 for rotation use. A gear 7 is fixed to a shaft 9 of a motor 8 for revolution use; it is engaged with a gear 91; as the gear 7 is turned, a part around the motor shaft 6 for rotation use of the rotation axis 3 which is fit freely to it, is turned; a rotation movement of the rotation axis 3 is caused around the center of a liquid tank. In this manner, an etching liquid is stirred by a rotation and a revolution of the substrate support body 1. Thereby, an omnidirectional liquid flow which is independent of the surface of the substrate is caused; accordingly, it is possible to make an etching depth, a cross-sectional shape and the like, uniform at a selective etching operation.

Title: Continuous evaluation device for exhaust smoke processor
Inventor: SAITO KEIZO
IPC: B01D53/30
Filed: 1989-04-20
Abstract: PURPOSE:To exactly and continuously measure the smoke density by cancelling a drift by providing a light receiving sensor for reference for receiving directly a light beam from a light source on a smoke meter provided on the upstream side and the downstream side of an exhaust smoke processor. CONSTITUTION:Smoke density of an unprocessed gas which is led in from an exhaust gas inlet 2 is measured by a smoke meter 5 and gas processed by an exhaust smoke processor 1 is measured by plural smoke meters 6. The measurement of the smoke density is executed by detecting an attenuation while the light beam of a light source 12 passes through the gas by a light receiving sensor 13. The output of the sensor 13 is inputted to an arithmetic processor and measured. In this case, the sensor 13 is influenced by high temperature exhaust gas and generates the drift, but it is cancelled by the output of the light receiving sensor 16 for reference for receiving directly the light beam of the light source 12 and the influence is eliminated. In such a manner, the smoke density and the smoke reduction rate can be measured exactly and continuously.

Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To control a pump operating frequency by an inverter part according to fluid pressure and control pump discharge pressure so as to keep target pressure constant by providing a fluid pressure detecting part, a Westco pump and an inverter part controlling the pump. SOLUTION: The detection signals of a flow rate sensor 37 and pressure switches 41 and 42 are outputted to a control part 36. In the control part 36, whether discharge output P of a Westco pump 35 is smaller than starting pressure PS 2 or not is decided based on the detection signal of the pressure switch 42 at first. When this decision is true, the pump 35 is started and an inverter control is performed so as to be P=PS1. Thus, power consumption of the pump 35 can be partially cut by performing the inverter control for discharge pressure P so as to make PS1 constant. Therefore, power consumption on a little water quantity side can be reduced by performing the inverter control by using the Westco pump 35.
