Title: Manufacture of piezoelectric ceramic resonator
Inventor: IINO TAKESHI
IPC: H03H3/02
Filed: 1988-06-29
Abstract: PURPOSE:To improve the mass productivity and the quality by sandwiching a piezoelectric ceramic element with a metallic plate to stick a conductive rubber inside it, adding a direct current electric field and executing the polarization. CONSTITUTION:A piezoelectric ceramic element 1 worked to the prescribed thickness is overlapped in a thickness direction, sandwiched with a metallic plate 2 to stick a conductive rubber 3 inside it from the vertical direction to the thickness direction and by adding a direct current electric field between the metallic plates 2, the polarization is executed. Thus, since the conductive rubber 3 is used, even when the electrode for polarization is not given, the adherence of the metallic plate 2 and the ceramic element 1 is satisfactory, polarization can be uniformly polarized, the heating is not caused by the sticking and separation after the polarization and the piezoelectric deterioration does not occur. Thus, the mass productivity and the quality can be improved.

Title: Electronic watthour meter
Inventor: SASANO KIYOSHI
IPC: G01R22/00
Filed: 1992-06-18
Abstract: PURPOSE:To obtain an accurate measurement value where influence of DC offset and light load characteristics is eliminated. CONSTITUTION:An adder 12 integrates an instantaneous value data output from an A/D converter 2 at each time indicated by an addition time setter 11 and then gives the result for each unit integration time and the integration count to an arithmetic unit 13. The arithmetic unit 13 divides the integration time by the integration count to calculate the DC offset per instantaneous value, thus generating a compensation data. An adder/subtractor 5 adds or subtracts the compensation data content to and from the output data of the A/D converter 2, thus eliminating the DC offset from the output data of the A/D converter 2. An adder 14 and an arithmetic unit 15 perform a similar processing to an adder/subtractor 6. A light load characteristic compensation data for compensating an error when a power feeder line is lightly loaded is set in a light load compensation value setter 16, the adders/subtractors 5 and 6 add or subtract the output data of the A/Ds 2 and 4 even for a light load compensation data, thus compensating the light load error.

Filed: 1989-06-22
Abstract: PURPOSE:To enable operation of plural stirring jigs with one operating shaft by preparing the jigs for stirring raw material solution reservoirs from a material having a smaller specific gravity than that of a raw material solution, separately mounting the operating shaft for operating the stirring jigs and providing a construction for stirring the raw material solution utilizing buoyancy thereof. CONSTITUTION:Plural raw material solution reservoirs 1 are provided on a cassette 13 for housing wafers 12 side by side in the vertical direction and a raw material solution 2 is introduced to the cassette 13 for growth of each layer to carry out multilayered liquid-phase epitaxial growth. In the process, the following construction is adopted. The respective raw material solution stirring jigs 4 are prepared from a material having a smaller specific gravity than that of the raw material solution 2 and an operating shaft 7 independent of the stirring jigs 4 is lowered to lower the stirring jigs 4. Thereby, when the raw material solution 2 is present in the solution reservoirs 1, the stirring jigs 4 float up by itself due to buoyancy thereof. If the operating shaft 7 is lowered, the stirring jigs 4 can be lowered to stir the raw material solution 2 by lowering and buoyancy thereof.

Title: Pencil sharpener
Inventor: WAKAMATSU KAZUNORI
IPC: B43L23/02
Filed: 1988-06-28
Abstract: PURPOSE:To prevent a pencil from entering an interior when a very short pencil is inserted by a method wherein a sensor for stopping operation of a pencil feeder by detecting a rear end of the pencil is established near a pencil insertion opening. CONSTITUTION:When a very short pencil 8 is inserted, a rear end of the pencil enters an interior of a pencil insertion opening before the pencil is sharpened and is sufficiently pointed, and the pencil passes an actuator 31. Then, the actuator 31 which has been retreated by being pressed by the pencil till then returns to an original position, an inside of a switch device 30 becomes in an intercepted state, and a motor 1 is stopped. When the motor 1 is stopped, rotation of a cutter 5 and action of a pencil feeder 9 are also stopped, and the pencil stands still at a position where the rear end part of the pencil has passed a little the acturator 31. Further, since the motor 1 is so made to be actuated only when the pencil presses an actuator 33 and the inside of the switch device becomes in a through state, the motor 1 is not rotated until the top of the pencil reaches a sharpening part.

IPC: H02K3/24
Filed: 1990-06-19
Abstract: PURPOSE:To ensure good connection between a resin magnet and a pawl type pole while successfully maintaining the cooling process of a field coil and the resin magnet by providing, to the resin magnet, a bottom collar part which is in contact with the inner most circumference of the pawl type pole and is extending in the circumferential direction while it is being separated through an air flowing path in the axial direction for the external circumference of the field coil. CONSTITUTION:A resin magnet 6 has an almost cylindrical bottom collar part 60 which is closely in contact with the inner most circumference of pawl type poles 5a, 5b and perfectly covers this inner most circumference. The internal circumference of the bottom collar part 60 is isolated by the predetermined interval from the external circumference of the field coil 2 and an air flowing path S1 in the axial direction between the internal circumference of bottom collar part 60 and the external circumference of the field coil 2 is used to cause the air F to flow in the axial direction. Thereby, heat radiation characteristic of resin magnet 6 and field coil 2 can be improved remarkably. Moreover, heat of the field coil 2 is not transferred in direct to the resin magnet 6 and therefore magnetic characteristic of the resin magnet 6 is never deteriorated. In addition, connection characteristic of resin magnet 6 and pawl type poles 5a, 5b is improved, preventing generation of play therebetween.

Abstract: PURPOSE: To increase the information compression rate by transmitting only the changed block pattern information in the block information and transmitting the flag information which is a block unit picture map.  
     CONSTITUTION: In case where there is a black and white pattern in picture (a), one scanning line is divided into each plural unit (8 bits = 1 byte), thus dividing into a total of 256(bytes) and forming a group of blocks. With the picture(a), the first scanning line transmits the total pattern information of 256 parts and register them, but in case of the second scanning line, the first byte, second byte,......are all in the same pattern and the pattern information is not transmitted and, therefore, the first byte "0", second byte "0"......are transmitted as the flag information (b) and registered. The compressed pattern information and flag information are transmitted as a pair, but in the first part of (a), only the pattern information of numericals (1)-(4) located outside of the left column is transmitted while at the same time (1) is transmitted as the flag and the register is changed.
