Title: Piezoelectric actuator
Inventor: HASEGAWA FUMIO
IPC: H01L41/09
Filed: 1990-10-30
Abstract: PURPOSE:To make it possible to exchange an elastic body and to contrive to prolong the life of the elastic body by a method wherein an element is provided in such a way that is hermetically sealed by a side plate, an expansion and contraction part and a housing part and is always applied a compressive force in the opposite direction to the displacement direction by a repulsive force. CONSTITUTION:A coil spring 8 is mounted on an axis 7f made to project to the outside through a side plate 7b and the spring 8 is compressed by a cap 10 via a press plate 11 so as to generate a prescribed repulsive force. As a fixing of the cap 10 and an outer cylinder 7a is carried out by screws, the cap 10 can be detached and the spring 8 can be exchanged. As the stroke of the spring 8 can be changed by changing the depth of screwing-in of the cap 10, a compressive force to an element 1 can be adjusted. Thereby, it is possible to exchange easily an elastic body and the life of the elastic body, which is used as a piezoelectric actuator, can be prolonged.

Title: Paste type cadmium negative electrode for alkaline storage battery
Inventor: HIRAKAWA AKIRA
IPC: H01M4/26
Filed: 1992-10-30
Abstract: PURPOSE:To restrain the diffusion of cadmium to the outside of an electrode for ensuring the high performance thereof, and provide an inexpensive electrode by forming a layer mainly composed of nickel hydroxide on the surface of an active material layer. CONSTITUTION:Regarding a paste type cadmium negative electrode for an alkaline storage battery where an active material layer mainly composed of cadmium oxide is formed on a conductive core material, a layer mainly composed of nickel hydroxide is formed on the surface of the active material layer. The formation of the layer on the surface of an electrode leads to the concentration of the nickel hydroxide at a boundary between a separator and the electrode. Thus, a soluble cadmium intermediate product tending to diffuse into the separator can be efficiently made to deposit, compared with a case where nickel hydroxide is added to an active material. Also, a special device is not required and, therefore, no increase in cost is sustained. According to this construction, the diffusion of cadmium from the electrode can be restrained, thereby ensuring the high performance thereof and preventing a cost increase.

IPC: G01S7/529
Filed: 1986-12-08
Abstract: PURPOSE:To easily search a target by providing an AGC control part with a data storage circuit and a processor circuit and suppressing a reverberation level which varies abruptly. CONSTITUTION:A received signal is A/D-converted 61 and inputted to a processor circuit 62, then detection and section averaging are performed with a constant-time clock supplied to a distance clock circuit 65, the data is stored in a storage circuit 63. The stored data 13 read out of the storage circuit 63, on the other hand, is compared by a processor circuit 62 with the current search signal to generate a control voltage having the opposite characteristics from the stored data, and the voltage is supplied to a D/A converter 64 and applied to the gain controller 51 of an AGC part 5 to control the gain of the received signal, thereby obtaining a stable output level. Consequently, the AGC control voltage is controlled with the stored data of the last search when the current search level is small with the A/D-converted data of the current search when said level is large to perform stable AGC control because variation in reverberation level is stored as data.

IPC: H04N1/46
Filed: 1987-11-24
Abstract: PURPOSE:To expand the degree of freedom of expression of a picture by combining a code obtained through the application of difference operation or differentiation operation to a space component of a picture and representing the density gradient and a code representing the space vector being a component piece constituting the picture so as to obtain a density potential. CONSTITUTION:A density detection section 3 detects the level of brightness or the density so as to obtain the density potential of the entire picture from the picture signal. A differentiation/difference arithmetic section 4, when the spatial change in the density potential is regarded to be a curve able to be differentiated, applies the numerical differentiation and when the stepwise change exists in the change, the difference operation is applied to obtain the density gradient. A coding processing section 6 uses the spatial vector and the density gradient in each position of the spatial vector in pairs to apply write processing to a picture memory 7. Moreover, the magnification/reduction or rotation/ movement processing of the picture is applied by the vector operation processing and the result is written in the picture memory 7. The change in the shape in each position of the picture pattern, the color density and its change are stored as a vector in the picture memory 7.

Title: Partial discharge measuring method
Inventor: MIYAZAKI TOSHIHIRO
IPC: G01R31/12
Filed: 1993-10-29
Abstract: PURPOSE:To make it possible to highly reliably measure a partial discharge by measuring partial discharges simultaneously for a plurality of objects and then comparing the magnitude of individual pulses. CONSTITUTION:Assuming the surge damps of surge damping elements 3A, 3B are 1/2 and 1/3, respectively, a noise of magnitude 6 intruding from an electricity imparting facility 1 side is detected as a noise of magnitude 3 by a detector 6A and as a noise of magnitude 2 by a detector 6B and the ratio thereof is 1.5. On the contrary, a partial discharge of magnitude 6 generated from a machine 4A is detected with magnitude 6 by the detector 6A for the machine 4A whereas it is detected with magnitude 1 by the detector 6B for the machine 4B because it is detected through two elements 3A, 3B. Since the ratio is as high as 6, a decision unit 7 can make a clear discrimination automatically. In practice, discrimination can be made between noise and a threshold value of partial discharge by injecting correction pulses into respective lead wires 2 of imparting electricity to the machines 4A, 4B and determining the ratio of magnitude of signals detected by the detected 6A, 6B.
