Title: Ceramic piezoelectric element and laminated type piezoelectric element
Inventor: NISHIDA MASAMITSU
IPC: H01L41/04
Filed: 1988-03-29
Abstract: PURPOSE:To reduce distortion generated at a boundary between the piezoelectric ceramics of a ceramic piezoelectric element and an electrode due to temperature change and to decrease the deterioration of the element by composing the piezoelectric element having substantially the same crystalline structure as that of the piezoelectric ceramics, the electrode. CONSTITUTION:The electrode of a ceramic piezoelectric element having piezoelectric ceramics and electrodes is formed of conductive oxide ceramics having mainly a pevroskite structure. The piezoelectric ceramics are preferably formed of pevroskite structure oxide. Thus, the ceramics and the electrodes are composed of the ceramics having substantially the same crystalline structure, thereby reducing a distortion at the time of baking end decreasing the deterioration due to the temperature change of the piezoelectric element. Since the ceramics and the electrodes can be simultaneously baked, manufacturing steps can be shortened. Since the electrodes are formed of oxide, their durability can be improved.

Abstract: PURPOSE:To stabilize the operation by supporting a support part of a contact shoe with a box member so that a space between the flat surface including the end surface of a magnetic pole and the surface of the contact shoe opposite to the magnetic pole is widened toward one side under the condition that the current is not applied to a coil. CONSTITUTION:A movable contact point spring 1 and a support part 11, which is provided in a central part of the movable contact point spring 1, are included in the same surface, but the movable contact point spring 1 and a contact shoe 2, which are unified at a central part through an insulating material 6, are arranged for integration so that a space between them is enlarged toward one side from a view of the side surface. The support part 11 is supported by a box member so that the flat surface including the end surfaces of magnetic poles 31, 32 and the surface of the contact shoe 2 opposite to the magnetic poles 32, 33 are widened toward one side from a view of the side surface under the condition that the current is not applied to a coil 5. As a result, even if the attracting force of the magnetic poles of a permanent magnet is bilateral symmetry, the attracting force of the NC side magnetic pole is made larger than a negative electrode, and the attracting force of the NO side magnetic pole is made smaller than the negative electrode, and the operation is thereby stabilized.

Title: Ceramic powder for electroplating
Inventor: UCHIDA KAZUKO
IPC: C25D7/00
Filed: 1992-02-27
Abstract: PURPOSE:To obtain the ceramic powder which can form a homogeneous electroplating layer at a high yield. CONSTITUTION:The ceramic powder is subjected to electroless plating, by which the specific resistance of the powder is adjusted to <=30OMEGAcm. The electroless plating layer is deposited at an adequate distribution density on the surface of the powder particles and provides a surface condition adequate for electroplating. The homogeneous electroplating layer is formed without the need for the electroless plating over a long period of time and, therefore, the burden on the maintenance and control of an electroless plating bath and the treatment of a waste liquid, etc., is decreased. The high-quality coating powder is thus inexpensively produced at the high yield.

Title: Linear ultrasonic motor and slide table employing linear ultrasonic motor
Inventor: YAMADA TOSHIO
IPC: H02K7/00
Filed: 1990-03-26
Abstract: PURPOSE:To obtain a linear ultrasonic motor, which can control the driving speed of a slider, and a slide table employing the linear ultrasonic motor by providing a transmission rod to be secured to first and second piezoelectric oscillator and the slider which is brought into pressure contact with the transmission rod. CONSTITUTION:Upon application of a voltage, a first piezoelectric oscillator 1 is excited in a specific direction. At that time, a variable resistor is connected at a predetermined resistance determined by the resonance point of first and second piezoelectric oscillators 1, 2. Excitation of the first piezoelectric oscillator 1 causes an elliptical vibration on the surface of a transmission rod 3 thus producing a perfect rightward traveling wave which is then absorbed by the second piezoelectric oscillator 2. Consequently, a slider 4 is driven to the left and a table 5, interlocked with the slider 4, is driven linearly and stably at a constant speed while being guided by a linear guide 6.

Abstract: PURPOSE: To obtain through coating a powder drug having improved dispersion properties in water a gain and capable of reaching the effective blood concentration quickly, by a simple method wherein a slightly water-soluble drug is ground in an aqueous solution of a water-soluble high polymer substance and dried.  
     CONSTITUTION: A slightly water-insoluble drug is ground in an aqueous solution of a water-soluble high polymer substance, e.g., hydroxypropyl cellulose, CMC, gelatin, etc. and dried so that the powder drug is coated. The coating is also carried out by grinding the drug in an aqueous solution of a thermally gelling water-soluble high polymer substance, followed by gelation through heating, separation, drying, and application.

Title: Salient point extraction device
IPC: G06T7/60
Filed: 1992-03-31
Abstract: PURPOSE:To extract only a true salient point in a short processing time without being affected by the connecting state of the edge of an image. CONSTITUTION:A salient point candidate extraction part 3 calculates respective mean density and dispersion of small masks set on the image by dividing into four areas, and assumes that the salient point exists in the neighborhood of the center of the mask when the mean density of only one area in the four areas is different from others and the dispersion in the area shows a small value. The mask is scanned on the image, thereby, a salient point candidate can be obtained. A salient point decision part 4 sets small areas for an obtained salient point candidate in the periphery of a candidate point, and decides the candidate point as the true salient point when a long ridge in a prescribed direction is detected in an edge strengthened image in the small area.

IPC: H04B10/079
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To easily comprehend the communication state, such as the presence of fault in a communication system of an optical space transmission system. SOLUTION: A light-receiving section 11 receives light of a prescribed wavelength range and applies photoelectric conversion to the light to obtain an electric signal. A level discrimination section 12 discriminates the level of an electric signal which has been converted from the optical signal received by the light-receiving section 11 to discriminate the strength of the received optical signal. Combining a peak hold circuit that detects a peak level of the signal and holds it, or an envelope detection circuit that detects an envelope of the signal and a level comparator configures the level discrimination section 12. A display section 13 selectively lights, e.g. plural light-emitting elements, in response to a range of the signal level based on the level discrimination result by the level discrimination section 12 to display the signal level.

Title: Method for checking ram
Inventor: UMEDA YUJI
IPC: G11C29/00
Filed: 1988-03-30
Abstract: PURPOSE:To widely shorten the time necessary for checking a RAM by forming the RAM into plural equal dimensional blocks, successively interblock- transferring a check pattern, and comparing a pattern passed through the last block with the check pattern. CONSTITUTION:Addresses in a RAM5 are partitioned into (n) equal dimensional blocks 7 by a CPU3. The CPU3 reads a first check pattern having a dimension equal to that of one block from a ROM4 and writes a first check pattern to a block 7 designated by a value (n) of an address counter 8 in the RAM5. The CPU3 reads the contents of this block 7, transfers the contents to the next block 7, successively interblock-transfers the check pattern from the first block to the last block by comparing the pattern passed through the last block with the check pattern, and decides whether the RAM5 is normal or not based on this compared result. Thus, the time necessary for checking the RAM can be widely shortened.
