Title: Control device for induction motor
Inventor: KAMIYAMA NAOHIKO
IPC: H02P23/03
Filed: 1982-03-19
Abstract: PURPOSE:To perform wide-range and good speed control by a method wherein a cyclo converter is operated as a variable frequency power source for power commutation motor at low speed and Scherbius operation is applied to an induction motor by using the cyclo converter at a high speed area. CONSTITUTION:A cyclo converter C is used as a variable frequency power source operating by power commutation by opening a switch S1 and by closing switches S2, S3. An induction motor IM is started under this condition. In this case, the variable frequency power source by the cyclo converter C is applied to the rotor side of the induction motor IM and a stator side is short-circuited by the switch S2. Therefore, a power frequency is varied by the cyclo converter. Accordingly, the induction motor IM is operated at variable speed. When the rotation of the induction motor IM arrives at perdetermined speed or over, the switches S1, S2, S3 are selected and the cyclo converter C is used as an inverter regenerating the secondary power of the induction motor IM to a power side.

IPC: H01L21/339
Filed: 1984-03-06
Abstract: PURPOSE:To enable to obtain a high signal output frequency at low power consumption by a method wherein the signal charge which will be transferred in a plurality of charge transfer elements is detected using the same charge detector. CONSTITUTION:The signal charge transferred through the transfer channels 25-1 and 25-2 is sent to a floating diffusion layer 30 through an output electrode 29 after passing through a common composite electrode. At this time, a voltage in proportion to the signal charge is outputted from a terminal 33. The signal charge sent to the layer 30 goes out to the outside of an element by applying a set pulse on a reset electrode 31. According to this constitution, the clock pulse to be applied to terminals 26 and 27 is f0/2Hz for the frequency f0Hz of the reset pulse and the signal output. As mentioned above, the transfer clock pulse is driven at one-half of frequency by applying the composite clock pulse of the frequency f0 on an electrode 28.

Title: Cathode-ray tube
Inventor: MIYATA YOSHIHIKO
IPC: H01J29/84
Filed: 1981-03-27
Abstract: PURPOSE:To obtain a cathode-ray tube by using an electron gun equipped with a compact ion trap which is short in whole length, a magnet for generating an ion trap magnetic field being contained in a neck tube of the cathode-ray tube bulb. CONSTITUTION:Although an electron beam and an anion are both bent by an inclined electromagnetic field between a second grid 23 and a third grid 24 and they almost nearly collide with the side wall of the third grid 24, the orbit 5 of the electron beam is again bent in the direction of the axis of the electron gun because of the magnetic field of an ion trapping magnet 3a. However, the orbit 6 of the ion with greater mass, moving at low speed, is practically not bent by the magnetic field, and the ion collides with the side wall of the third grid 24 and is trapped. It is also naturally possible to attach the ion trapping magnet 3a to a glass rod supporting the electrode. The third grid 24 or part of it may be composed of a magnetic material for magnetization. The position where the ion trapping magnet is attached is not restricted by a part for holding a deflecting yoke, so that the electron gun may be put near the fluorescent screen. Such a construction as this thus contribute to the curtailment of the whole length.

Abstract: PURPOSE: To make it possible to easily cover embossed patterns, pinholes, color difference or the like developed in a groove bottom portion of a decorative board by a method wherein an aqueous slurry paint is coated within grooves of a decorative board with grooves and heated to form a coating within grooves.  
     CONSTITUTION: In case of forming grooves 4 to a printed decorative board comprising three layers of a surface veneer panel 1, a core panel 2 and a back surface veneer panel 3, because a fiber direction of a veneer panel 1 and a core panel 2 is different, embossed patterns are formed in a groove bottom portion so as to traverse the groove and, because an inferior veneer panel is generally used as a core panel, pinholes, color difference or the like are exposed and the appearance is remarkably damaged. Therefore, an aqueous slurry paint is coated in grooves 4 of a decorative board with grooves and, if the paint overflowed from grooves 4 is wiped off, a pattern printed on a veneer panel 1 is not stained. Subsequently, the coating 7 is formed by heating to a groove bottom portion 5 and a side wall portion 6.

Filed: 1988-02-29
Abstract: PURPOSE:To provide a large capacity of pump for limiting differential motion by providing a gear pump unit on between either engagements on respective gears of a first, a second pinion gears and a first, a second side gears. CONSTITUTION:If a wheel on a first output shaft 41 side slips in a muddy place, the output shaft 41 becomes in low load and a second output shaft 45 becomes in high load. Thereupon, differential torque between the output shafts 41 and 45 is transmitted to a first pinion gear 23 from a second pinion gear 31 via a second idle gear 33 and a first idle gear 25 for becoming to be applied as driving force for the output shaft 41 and nearly zero driving force is transmitted to output shaft 45. At this time, a first side gear 39 and a second side gear 43 rotate on meshing in accordance with differential rotation between the output shafts 41 and 45. Thereupon, a gear pump 47 generates vacuum pressure on suction side and positive pressure on delivery side. Therefore, as differential rotation becomes large, pressure difference between suction side and delivery side of the gear pump 47 gets large for making differential limiting force increase as pressure difference increases to get out of slipping condition.
