Title: Angular velocity sensor
Inventor: TERAO HIROAKI
IPC: G01C19/56
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of the mechanical quality coefficient by forming a groove in the vicinity of a node part of bending vibration of a vibrating body, and supporting the groove with a supporting member. SOLUTION: The sensor part 20 is constituted of a vibrating body 21, a piezoelectric element 23 and a weight 28. The piezoelectric element 23 is attached to the upper face of the vibrating body 21, and a detection electrode 24, a feedback electrode 25 are set on the upper face of the piezoelectric element 23. An electrode 27 is set on the lower face of the piezoelectric element 23. The weight 28 having a center axis agreeing with a Z axis is attached to the lower face of the vibrating body 21. A U-shaped groove 21a is formed in the vicinity of a node part 26 of the vibrating body 21, which is supported by a cylindrical supporting member 29. The vibration state is stabilized more as the groove 21a is closer to the node part 26. When an angular velocity acts to the sensor, the weight 28 moves because of a Coriolis force, thereby deforming the sensor part 20. Electric charges are generated at the detection electrode 24. A direction and a size of the angular velocity are detected from the amount of the electric charges.

IPC: G02F1/13
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To reduce the service life deterioration of a light source lamp due to infrared ray. SOLUTION: A lens array 200 is arranged on an optical path of emission light outgoing from a light source part 100 so that the lens surface with a curved surface shape of the lens array 200 becomes an incident surface of light. A filter FIR interrupting at least the infrared ray is formed on the lens surface with the curved surface shape of the lens array 200. Since the infrared ray IR outgoing from the light source part 100 is reflected radially by the filter FIR, the infrared ray IRR again made incident on the light source lamp 101 is reduced to a certain extent, and the occurrence of the damage, deformation and cloud, etc., in the lamp due to the temp. rising of the light source lamp 101 is reduced.

Abstract: PROBLEM TO BE SOLVED: To make it possible to increase/decrease the feed rate of a cleaning water (filtrate) automatically in accordance with an increase/a decrease in the quantity of cleaning water effluent and thereby facilitate an operating control by extracting a contaminated granular filter medium from the lower part of a filtration bed, and taking out a water for transporting the filter medium and the cleaning water effluent separately. SOLUTION: Foreign matter contained in an untreated liquor supplied from a supply port 3 into a filtration tank 1 is captured while the foreign matter ascends through a granular filter medium 2 layer, and a filtrate is overflown from the upper part of the filtration tank 1 to be taken out of a drain port 4 to an area outside this floating bed filtration device. In this case, the ascending current of the filtrate and the reflective ascending current of water for transporting the filter medium 2 are generated in a cleaning cylinder 11 submerged in the internal upper part of the filtration tank 1. Further, the ascending current separated from the filter medium 2 carrying the foreign matter is drained from a drain pipe 14 as waste water to be cleaned.  On the other hand, the filtrate is taken out of an extraction cylinder 21 as water for transporting the contaminated filter medium 2 extracted from the lower part of a filtration bed. This filtrate is circulated through a circulating water pipe 9, a pump 8, an ejector 7 and a transport pipe 10 in that order. Thus it is made possible to easily perform an operating control even when the pollution load of the untreated liquor is varied.
