Title: Angular velocity sensor
Inventor: MOCHIDA YOICHI
IPC: G01C19/5755
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To obtain an angular velocity sensor whose detection sensitivity in a displacement detection part is increased by a method wherein the separation size between a fixed-side electrode for detection and a moving-side electrode for detection at the displacement detection part is made small by a control part. SOLUTION: A vibrating body 28 which is supported so as to be capable of being vibrated in the horizontal direction is supported by support beams 27, 27,... in respective support parts 26 fixed to a substrate 22, and a rugged electrode 34 and a rugged electrode 36 are formed in a part faced with the substrate 22 and the vibrating body 28 in such a way that they are engaged in a state that they are separated from each other. Then, a control part 40 is formed of the rugged electrode 34 and the rugged electrode 36. When a DC voltage is applied across the electrode 34 and the electrode 36, the vibrating body 28 is brought close to the side of the substrate 22 by an electrostatic attractive force.  A displacement in the separation size between substrate-size electrode 33 and tip-size electrodes 38 at the recessed and protruding electrode 36 can be detected with high sensitivity by a capacitance as a displacement in Coriolis' force.

Abstract: PURPOSE:To obtain large current per weight of a platinum group by manufacturing a cake by filtrating a mixture of hydrophilic and water repellent carbon black, a solvent, and polytetrafluoroethylene, and also manufacturing a cake by filtrating a mixture of water repellent carbon black, a solvent, and polytetrafluoroethylene. CONSTITUTION:A cake is manufactured by filtrating a mixture of hydrophilic and water repellent carbon black, a solvent, and polytetrafluoroethylene, and also a cake is manufactured by filtrating a mixture of water repellent carbon black, a solvent, and polytetrafluoroethylene. The both cakes are pressed and bonded to form a complex sheet having a specified thickness. The complex sheet is heated to remove the solvent to prepare a gas diffusion electrode raw material sheet. A platinum group compound solution is impregnated in a reaction layer raw material sheet containing the hydrophilic carbon black, and heat- decomposed to deposit a metal and/or an oxide of the platinum group on the sheet. Thereby, a gas diffusion electrode with a reaction layer and a gas diffusion layer is manufactured. The gas diffusion layer in which an electrolyte comes in contact with the whole platinum group metal in the reaction layer to undergo the catalytic reaction can be manufactured.

Title: Flux coating device
Inventor: TANIGAWA YOSHIYUKI
IPC: B23K3/00
Filed: 1980-02-28
Abstract: PURPOSE: To avoid waste of flux by installing a means which detects materials to be soldered on the carrier and by making oscillation of the oscillator of ultrasonic flux coating device intermittent through its signal, so that the oscillation is stopped when no flux is coated.  
     CONSTITUTION: Material to be soldered 2 is held by carrier attachment 3 and moves on carrier 1, and, when its front end passes between light projecting section 9 and light receiving section 10 of the photodetector, the light is intercepted. When the light is intercepted, the timer circuit operates, and when the front end reaches near flowoff port 4 of ultrasonic flux coating device 5, the liquid flux is atomized and spouted through port 4. When material to be soldered 2 proceeds further and the light of photodetector is transmitted, the timer circuit operates and the ultrasonic oscillation is stopped after the same period as mentioned above, and then the atomization is stopped and spout of flux is also stopped. With this mechanism the flux consumption can be reduced.

IPC: F15B11/02
Filed: 1984-02-15
Abstract: PURPOSE:To facilitate fine control by fitting one end of a metering pin movably in a poppet, and providing this metering pin with a means to put the spring chamber in communication with the primary side port when the poppet has moved too much. CONSTITUTION:One end of a metering pin 4f installed in a spring chamber 4b is fitted movably in a poppet 4a, and this metering pin 4f is equipped with a means to put said spring chamber 4b in communication with the primary side port 41 when the poppet 4a has moved excessively. Thereby the pressure P1 at the primary side port 41 flows into the spring chamber 4b, when the poppet 4a opens too much, to eliminate pressure difference between the two chambers, and now the poppet 4a moves in the direction of opening the valve. According to this arrangement the poppet 4a can be opened and closed proportional to the pilot pressure Pi, to ensure that fine control is performed easily.

Title: Electrostrictive effect element
Inventor: MIZUNO SEIJI
IPC: H01L41/09
Filed: 1989-02-03
Abstract: PURPOSE:To prevent a crack from occurring and growing by employing an electrode containing, in addition to metal main ingredient, partially stabilizing zirconia as an inner electrode. CONSTITUTION:Piezoelectric elements 2 and inner electrodes 3 are alternately laminated, and the electrodes 3 are electrically connected at every other layer. An electrode containing partially stabilizing zirconia is employed, in addition to metal main ingredient, as the electrode 3. The zirconia includes, for example, zirconia in which 4-11% MgO or/and CaO is solid dissolved. When the element is composed of the electrode containing such partially stabilizing zirconia, metastable tetragonal crystalline zirconia in the inner electrode absorbs breakdown energy to cause a martensite phase transfer to a monoclinic crystal of low temperature stable phase, thereby absorbing to alleviate a breakdown stress. Thus, even if the element 2 is largely displaced, a crack is scarcely generated.

IPC: H01F27/28
Filed: 1995-02-14
Abstract: PURPOSE: To provide winding parts such as transformer or choke coil, etc., suitable for use in small-sized devices. CONSTITUTION: Both outer legs 3b and 4b of E-shaped cores 3 and 4 are formed thin in a manner that they are floated up from the central legs 3a and 4a thereof and terminal pin inserting parts 2b are prepared on a bobbin 2 at the positions opposite to the legs 3b and 4b of the respective cores 3 and 4.

Core placing parts 2c that are thinner than the parts 2b is formed on the bobbin 2. Therefore, the parts 2c of the bobbin 2 that determine the total height of winding part 1 becomes thin and the legs 3b and 4b of the cores 3 and 4 opposite to the parts 2b of the bobbin 2 also become thin.  Thus, the winding part 1 can be formed thin without being influenced by the thickness of the parts 2b of the bobbin 2.

Abstract: PURPOSE: To obtain a suture thread easy to be identified and with improved smoothness in surface, flexibility, uniformity and visibility, by providing a fiber of a different color from other filaments of suture threads in at least one filament among the suture threads including a plurality of spirally set adapted filaments. CONSTITUTION: An outside thread 32 of a spirally set suture thread 30 is arranged in a spiral pattern to go up from the lower left side to the upper right side, as the outside thread 32 performs precession around the outside surface of the suture thread 30. As the pattern spirally proceeds, individual threads on the outside surface are oriented in parallel to each other and to the longitudinal length of the suture thread 30 when the thread reappears continuously in the spiral pattern. Of the spirally set suture threads 30, at least one thread being of a color different from the others, are formed of four or more interwoven threads. Because of the parallel arrangement of the outside suture threads, the smoothness is improved, and because of the crossover of the threads, the flexibility is improved.

Abstract: PURPOSE:To minimize the scale and cost of equipments for manufacturing a side board, by adopting such a fabricating procedure as to conduct preliminary bending step by using a press brake and then execute roll forming process by using a small number of forming rolls. CONSTITUTION:A work W is pressed between a bottom die D1 and a top die D2 to form bent sections 21 and 22 of a top reinforcement part 2.
