Title: Controller for induction motor
Inventor: YANASE TAKAO
IPC: H02P23/04
Filed: 1987-06-15
Abstract: PURPOSE:To obtain quick accelerating and decelerating performance while contriving the reduction of magnetic noise, by a method wherein a flux commanding value is changed in accordance with the magnitude of primary current upon stationary running while a rated flux is provided upon accelerating and decelerating. CONSTITUTION:In the condition of stationary running, the output of a coincidence circuit 11 is 'L' level whereby a switching circuit 12 selects the output f(I) of a magnetic flux limit operating circuit 6 and provides the output as the multiplying input of multipliers 9a-9c. Accordingly, a flux commanding value is changed in accordance with the magnitude of a primary current in the condition of stationary running. The output of the coincidence circuit 11 is changed into 'H' level upon accelerating and decelerating. According to this change, a switching circuit 12 selects a value '1' and transmits it to the multipliers 9a-9c. As a result, the flux commanding values OR', OS', OT', inputted from the multipliers 9a-9c into a flux control PWM circuit 3, may be switched to values, providing rated fluxes.

Title: Refrigerant compressor
Inventor: YAMAZAKI YASUHIKO
IPC: F04B41/06
Filed: 1988-06-20
Abstract: PURPOSE:To lessen the amount of lubricant movement when the difference in pressure is built up between respective crank rooms by arranging connecting ports for uniform oil pressure piping in proximity to the standard oil level of each crank room in a refrigerant compressor wherein plural numbers of compressors are operated in parallel. CONSTITUTION:After refrigerant gas compressed by plural numbers of compressors 1a and 1b has been discharged out of an outlet pipe 3, it is sucked in again into the respective compressors 1a and 1b through an inlet pipe 2. At this moment, when the difference in pressure is built up between respective crank rooms 12a and 12b, lubricant 8 is moved to the side of low pressure. However, since each connecting port 6a and 6b of uniform oil pressure piping 7 is positioned at the height of each standard oil level 9a and 9b, the movement of lubricant 8 is only caused by the difference A in oil level between the oil level at the time of the difference in pressure built up and each standard oil level 9a and 9b. Each upper oil level 10a and 10b is therefore equal to the sum of the oil level A and each standard oil level 9a and 9b, and an increase in oil level is little, thereby making it possible to prevent oil hammering phenomenon and the like.

Abstract: PURPOSE: To considerably reduce the number of wirings between superposed frequency divided signal generating part and the circuits making use of the outputs thereof by serially sending out plural stages of frequency divided signals corresponding to the scals frequencies of respective pitch names.  
     CONSTITUTION: The frequency divided data forming part 40 of a superposed frequency divided signal generating part 18 subsequently series-shift the holding contents of FFs 1 thru 7 for delay during series addition operation and add the timing signals P from the transmission part 41 to the data of the lowest bits (bits of FF1). Controlling of whether this operation is performed or memory operation is performed is accomplished by the output of set-reset type FF57. When the output is "1", the signal of a shift line 58 becomes "1" and the holding data are shifted from the FF 7 to FF 1. Next, the data of the FF 1 are added to the signal P or the carrier signal from FF 54 for delaying in an adder 53 and then inputted to the FF7, the frequency dividing data Q 1  thru Q 7  whereby are then serially outputted via line 64, OR 65, AND 66. Thereby, the number of wirings between the associated circuits may be considerably reduced.

Title: Method for detecting horizontal device of rising and lowering device for wall surface
Inventor: WATABE MASAKUNI
IPC: G01B11/00
Filed: 1992-06-10
Abstract: PURPOSE:To regularly detect the horizontal deviation of a cage regardless of the swing of the cage in a building, etc., which can not adopt a Marion system. CONSTITUTION:A cage 10 raised and lowered facing a wall surface has a light receiving sensor 148. On the top end of the arm 140 of a roof car C, a laser oscillator 144 for oscillating a laser beam R is mounted. The laser beam R oscillated from the laser oscillator 144 is refracted by a reflecting mirror mounted on a rotating body rotated with the oscillating direction of the laser beam R from the laser oscillator 144 as a rotating shaft, and the scanning orbit surface forms a vertical surface H to the wall surface. Thus, even if the cage 10 is separated from the wall surface by the effect of wind, the light receiving sensor 14 is situated on the scanning orbit surface drawn by the laser beam R, and can receive the laser beam R. Therefore, the horizontal deviation of the cage 10 can be regularly detected regardless of the swing of the cage 10.

Abstract: PURPOSE:To improve reliability on a radiation control pocketbook by simplify ing input operation in a touch sensor type while mounting an improper input control function. CONSTITUTION:A power supply is turned on, and an initial screen is liquid- crystal displayed on a touch-sensor screen 3 by a computer 2 for screen display. When a radiation control pocketbook is inserted into a radiation-control pocketbook printer 4 and a personal control number is input and operated in a touching manner on the touch-sensor screen 3, electricity is conducted through an automatic entry device 12 and a host computer 5 by a connecting cable 8. The display screen of the touch-sensor screen 3 is changed unto a screen having the same contents as the pocketbook. Since previously registered information data, etc., are displayed automatically, a page to be entered anew is called, and a screen at a place to be entered is touched. When there is an error in input contents, an automatic entry erroneous-input preventive function works by collation with entry items in a floppy 7 for preventing erroneous entry, and the error is displayed on the screen 3, thus conducting correction.

IPC: G01S13/93
Filed: 1992-06-10
Abstract: PURPOSE:To provide a car collision preventive radar equipped with self-failure sensing function which can senses and inform the driver of eventual failure in the radar itself. CONSTITUTION:A car collision preventive radar mounted on the car itself emits a high frequency signal from an oscillator 1, amplifies by an amplifier 2, multiplexes the frequency by a multiplexer 3' into a specified magnification, gives the result to any car or obstacle ahead through a signal branching means 4, and mixes the obtained reflex wave with one of the high frequency signals branched by the means 4. The relative distance between the car concerned and the ahead car or obstacle and relevant information are generated by subjecting the frequency components of the mixed signals by a computational processing means to serve for preventing collision. The multiplexer 3' is equipped with a function to sense the drain voltage generated in the multiplexer itself and emit the result, and failure in the radar is known by monitoring this drain voltage emitted from the multiplexer 3'.
