IPC: H03H9/25
Filed: 1985-11-08
Abstract: PURPOSE:To prevent the reflection at the end face by adhering a base bottom onto a substrate and overflowing a part of the adhesive to the lower end of the side face. CONSTITUTION:The piezoelectric substrate 1 is made of a material such as a crystal or a piezoelectric ceramic and rectangular and the thickness is nearly 0.5mm. An interdigital input electrode 2 and an output electrode 3 are provided on the substrate 1 and the direction connecting, both the electrodes is the progressing direction of a surface acoustic wave.

Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To eliminate dust which is adrift around bedding or matting and also prevent dust from residing on the surface of the bedding or the matting by using a Japanese mattress beater. SOLUTION: A dust sweeping tool 13 is fixed to the midpoint of a handle 2 on the Japanese mattress beater 1 in such a state that the dust sweeping tool 3 rises from a base 4. Thus the dust sweeping tool 3 becomes flexible simultaneously with an action to beat bedding or matting by gripping the handle 2 of the Japanese mattress beater 1 and consequently, the dust sweeping tool 3 hits the Japanese mattress beater 1 to bring about the same effects as when an air is stirred up by a fan. That is, the dust blown up from the bedding or the matting can be fanned away.

Filed: 1986-10-24
Abstract: PURPOSE:To relaxing the restriction to the position of installation and to enhance the efficiency of a water wheel device by supporting a pair of front and rear shafts, rotatably between a pair of hulls of a catamaran, by longitudinally stretching a chain between sprockets provided at both ends of each shaft, and by laying water receiving vanes between support rods supported to the chain. CONSTITUTION:A water wheel device is installed on a catamaran 1 which is anchored on a river. Water blades 23 which are supported by a chain 12 stretched between sprockets 11, through the intermediary of support rods 21, receive the water stream of the river which flows through the water channel 4 between a pair of hulls of the catamaran 1 so that the chain 12 is rotated as the catamaran advances, and therefore, the sprockets 11 are rotated. Accordingly, shafts 7 supporting the sprockets 11 are also rotated, and therefore power are obtained through, for example, these shafts 7. When the level of water varies, the catamaran 1 is raised and lowered in association with the variation, and therefore, the positional relationship between the water receiving vanes 23 and the water stream is maintained to be constant. Further, more than two of the water receiving vanes are always located under water so that the energy conversion efficiency may be enhanced.

Title: Mold for molding
Inventor: MAMIYA HIROKUNI
IPC: B29C45/26
Filed: 1992-09-24
Abstract: PURPOSE:To preclude an outflow of resin due to falling of a bushing in a lead wire part by locating a larger cross-section areal part of the bushing to be arranged on the lead wire in the inside of the mold, and by grasping the remaining small cross-section areal bushing part in the separation part of the mold. CONSTITUTION:The bushing 3 is featured such that since a large cross-section areal part to be a part arranged in the inside of a mold resides, and thereby the stepped surfaces 33 between them and the small cross-section areal part 32 are engaged with the inside surfaces of an upper mold 41 and a lower mold 42, the bushing 3 is not substantially extruded and, therefore, never falls from the mold even when the molding pressure of resin 5 Is large. For this reason, an outflow of resin 5 never occurs as in the case of a prior art mold due to such falling. The grasping by the large pressing force is not required by the upper mold 41 and lower mold 42 as in a prior art manner with respect to a small cross-section areal part 32 of the bushing 3. As a result, the bushing 3 is not damaged at all.
