Title: Stacked piezoelectric actuator
Inventor: ASHIDA KOKI
IPC: H01L41/083
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent local extension of an actuator caused by variations in generation of heat of piezoelectric plates and increase the durability of the actuator by gradually reducing the areas of inner electrodes as they reach the central part of a stacked body of the piezoelectric plates. SOLUTION: A discoidal piezoelectric plates 11 is a sintered body made mostly from Pb(ZrTi)O3. A plurality of such piezoelectric plates 11 are stacked, with an inner electrode 12 constituted of two layers of a conductive adhesive being interposed between each two piezoelectric plates. In order to gradually reduce the areas of the inner electrodes 12 as they reach the central part of the stacked body of the piezoelectric plates 11, a pattern of a different area is preliminarily formed on each piezoelectric plate 11 by screen printing. The areas of the inner electrodes 12 in the central part are about 0.7 to 0.85 of that at the upper and the lower end part. By forming the inner electrodes in such a structure, generation of heat by the piezoelectric elements in the central part of the stacked body of the piezoelectric plates can be reduced during operation, thereby suppressing local extension of an actuator caused by generation of heat by the piezoelectric elements in the central part and providing the actuator with high durability.

Title: Method for washing and restoring semipermeable membrane
Inventor: WATANABE KOHEI
IPC: B01D65/06
Filed: 1985-03-12
Abstract: PURPOSE:To enhance washing effect and to easily restore the filtering capacity of a semipermeable membrane by washing, by using ethylene glycol monoacetate or a specific esterified compound of ethylene glycol as a detergent. CONSTITUTION:One of ethylene glycol monoacetate, ethylene glycol diethyl ether, ethylene glycol dimethyl ether, ethylene glycol monoethyl ether, ethylene glycol monophenyl ether, ethylene glycol monobutyl ether and ethylene glycol monoethyl ether of a combination of two or more of the above-mentioned compounds is used as a detergent to wash a semipermeable membrane. By using these detergents, the contaminant adhered to and accumulated on the semipermeable membrane is sufficiently removed and filtering capacity is recovered and, therefore, the semipermeable membrane can be repeatedly used over a long period of time and, because each detergent contains no metal ion, said detergent can be used in an ultra-pure water making field.

Title: Sealed vessel lid made of thermoplastic resin
Inventor: SHIMA TORU
IPC: B65D41/18
Filed: 1988-03-01
Abstract: PURPOSE:To remarkably reduce cracking of a lid and a vessel body on fixing the lid and to give enough falling strength and buckling strength, by using a thermoplastic resin with a lowerdensity than that of the material of the vessel body as the lid material but within specified range of the density. CONSTITUTION:The bend 8 of a vessel body 1 is fitted between the inner flange 15 and the outer flange 16 of a lid 2 and then the lid is pressed down by a high pressure. At the time, the inner flange 15 does not yield inwardly, but the outer flange 16 yields outwardly. The outer flange 16 moves back to the original position due to its restoring force as soon as the top end of a wedge type claw 17 reaches the same height as that of the bottom end 8A of the bend 8. As a result, the bottom end 8A of the bend 8 is secured by the claw 17 to cover inseparably the vessel body 1 by the lid 2. For the material of the lid 2, thermoplastic resin, particularly high density polyethylene and a mixture with straight chain low density polyethylene are used, which are of lower density as much as 0.949-0.959g/cm<3> than that of the material of the vessel body 1. It has a large buckling strength and also a large falling strength. Accordingly, cracks or other defects on fixing the lid do not arise in the lid 2 and the vessel body 1.

Title: Rotating body provided with self-balancing function and rotating device
Inventor: IWAKI YOSHIYUKI
IPC: G01M1/30
Filed: 1994-02-21
Abstract: PURPOSE:To balance a rotation without performing a drilling operation for balancing and the additional operation of counter-weighting by a method wherein a ringed groove is formed inside a rotating body and a gellike fluid is injected into the groove. CONSTITUTION:A rotating body 10 is formed into a metallic or resin doughnut- shaped ringed body. A groove is formed in the ringed body 11. A gellike fluid 12 like a silicone gel is injected into the groove. Thereby, when the rotating body 10 is rotated, the gellike fluid 12 in the groove in the ringed body 11 moves in a direction in which a rotation unbalance is eliminated, and the rotating body is self-balanced. As a result, it is not required to balance the rotating body 10 mechanically; a production line is simplified; and the time required for an assembly operation can be shortened sharply.

Title: Water cooling system cooling plate
Inventor: SUMIYA MINORU
IPC: H05K7/20
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To enable setting a temperature at a plurality of steps with one cooling plate, by installing a bypass flow path which is directly connected with an exist port from each branch part, and reducing the flow rate of cooling water flowing in a meander flow path in accordance with desired cooling capability of the respective regions sequentially from the upper stream side. SOLUTION: A cooling plate is divided into a region A and a region B, a branch plate 6 is arranged in the boundary part of them, and a bypass flow path 7 directly connected with an exit port 3 from the branch part is arranged. In a flow path from an inlet port 2 to the branch plate 6, cooling water whose amount is equal to the inlet flow rate flows. Behind the branch plate 6, the cooling water is divided into a meander flow path and the bypass flow path 7. When the distribution ratio of flow rate by the branch plate 6 is 1:1, cooling water whose flow rate is equal to a half inlet flow rate flows in both of the respective flow paths. In this case, the ratio of cooling capability can be arbitrarily set by taking arbitrary heat dissipating area ratio and flow rate distribution ratio.  As a result, cooling operation corresponding to the number and the kind of equipments which need cooling is enabled.

Title: Ignition timing controller for engine
Inventor: SUGANO YOSHIAKI
IPC: F02P5/15
Filed: 1988-02-29
Abstract: PURPOSE:To make proper ignition timing settable to any variation in load by reducing a moderating effect of compensation for the ignition timing as long as the specified time since a load change has been detected. CONSTITUTION:A controller 30 compensates ignition timing from a deviation between mean speed and momentary speed of an engine 1 at an idling state when an idle switch 12A is turned to ON. Here a microcomputer 32 erects a flag in response to a signal read from an air-conditioning switch 19 via a driver 40, and judges of whether load of the engine 1 is changed or not by comparison between both states of the last and this time flags. If the load is changed, lag time is set to a timer 38, and a load means processing gain of the momentary speed finding the means speed at the idling state is changed till the lag time comes to zero. With this constitution, since a moderating effect is made smaller and the means speed is made so as to be followed to a rise in the momentary speed, the ignition timing is not controlled in the timing delay direction and thus the engine is made reachable to the required speed so quickly.
