Abstract: PROBLEM TO BE SOLVED: To certainly eliminate biting-in of sand and earth into door elements so that door opening and closing are not hindered by the sand and earth floating in the water and having deposited and equip with an adjusting function to allow generating an opening for communications in any position complying with the given conditions such as deposition of sand and earth, water level in the reservoir basin. SOLUTION: A lower door element 5 is made in a channel shaped formed by tying a bottom accommodation part 51 fitted approx. perfectly in a bottom accommodation chamber 31 positioned lower than the bottom surface of a communication hole with side frames 53 on both sides elevating and sinking along the side edge of a case 3, and the downstream corner of the oversurface of the bottom accommodation part is cut off so that an inclined surface 52 is formed having an angle θ greater than the reposing angle of sand and earth. An upper door element 4 is furnished with a bottom projection 41 which is in tight attachment with the inclined surface when the gate is fully closed. Because no sand and earth can stay on the inclined surface, the flow path is shut perfectly.  The risk of sand and earth biting into the gap between the sliding surfaces of the upper and lower door elements is very small, as the sliding surfaces are limited to metal touch of very small width.

Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To strongly joint materials without eluting aluminum by brazing a ceramic-aluminum composite material to an aluminum oxide sintered body using a composition material composed of a given proportion of aluminum, copper, and titanium. SOLUTION: This brazing filler metal 9 is composed of 57-64 weight% aluminum, 28-31 weight% copper, and 5-15 weight% titanium. The brazing filler metal 9 joints a heat dissipating plate 8 consisting of a ceramic-aluminum composite material and an insulating substrate 1 consisting of an aluminum oxide sintered body. The brazing temperature is not higher than 630 deg.C, and aluminum is note eluted from the heat dissipating plate 8 when the heat to melt the brazing filler metal is applied. Since active metallic titanium is contained, it is not necessary to form/adhere a metallized layer on the insulating substrate 1 before brazing is done. A ceramic-aluminum composite material is strongly brazed to a ceramic material at the joint strength of 1 kgf/mm2 or more.

Abstract: PURPOSE:To prevent the wall thickness from moving uselessly and the forming accuracy of a peripheral surface from reducing by mounting a countering on a step part and regulating deformation in the diametric direction on the peripheral side of the step part. CONSTITUTION:A slug 11 having a stepped recess 10 formed previously on the lower end face in the axial direction is inserted into the inside of the guide part 5a of a guide 5.

Title: Attitude controller for antenna on moving body
Inventor: HAYASHI TAKESHI
IPC: G01S3/44
Filed: 1990-11-30
Abstract: PURPOSE:To reduce the installation space of the title controller, to simplify attitude correcting operation and to decrease the cost of the controller by stopping the turning and driving in the elevation direction when the received signal level becomes the optimum level during the turning and driving of an antenna. CONSTITUTION:At first, a search instruction means 1 instructs searching and sets a BS antenna in the attitude that is directed to a radiowave source, e.g. a geostationary satellite. Then, attitude correction in association with the directional change and rolling change of a moving body acts. When the received signal level of a BS receiver BSR becomes less than the optimum level, a yaw- angle-change-tracking correcting means (MPU) 4 turns and drives the antenna Ant within a specified range in the elevation through an elevation mechanism 151. When the received signal becomes the adequate value level during the turning and driving, the turning in elevation is stopped. Even if the attitude of the antenna Ant determined by a turning and driving control means (MPU) 4' is slightly deviated in elevation, the deviation is automatically corrected. Thus, the providing space of the controller is reduced, and the cost of the controller can be decreased.
