Title: Primary voltage control variable speed controller
Inventor: KOBAYASHI SUMIO
IPC: H02P27/02
Filed: 1978-06-21
Abstract: PURPOSE: To improve efficiency and a power-factor, by decreasing higher harmonics by providing this controller with a change-over mechanism for changing over the impedance of the primary winding of a motor by the change of connection in a high-speed range and a low-speed range.  
     CONSTITUTION: A motor is operated in ▵connection in voltage V 1 , and the  number of revolution in the case when load torque is Tl is made to be N 1 . The number of revolution N 3  is produced in the same voltage V 1  by changing over winding to Y by means of a change-over appliance 9 of ▵-Y when the motor is operated at a low-speed. The number of revolution N 4  is yielded in the same voltage V 2  by changing over winding to Y by means of the change-over appliance 9 of ▵-Y if the number of revolution is N 2  when ▵connection in voltage V 2 . Thus, high voltage is necessary even when a low-speed if operating the motor in ▵connection when the number of revolution is not less than N 3  and in Y connection when it is not more than N 3 . This device need not delay a firing angle, ensures few higher harmonics, improves efficiency and betters a power-factor because conductive phase does not delay.

Title: Dimming checker
Inventor: KIUCHI MASAYOSHI
IPC: H05B41/32
Filed: 1979-06-15
Abstract: PURPOSE:To make possible the checking of dimming without complecating constitution by applying light emission stop signal to charging completion signal output terminal and displaying this. CONSTITUTION:Upon completion of charging of a main capacitor 7, a neon tube 113 goes on and a transistor 109 conducts to apply the photoelectric complesion signal through a resistance 107 to the charging completion signal output terminal C. This is displayed by lighting of the LED or the like which is connected to the terminal C. On the other hand, the connection of contacts X1, X2 upon opening of the shutter causes a thyristor 25 to conduct and this lets the flash emission of a discharge tube 33 be done. When the quantity of the light reflected from the subject reaches the specified one, the transistor 77 of a light emission stop signal generating circuit goes ON owing to the drop of its base potential. Then, thyristors 45, 39 turn ON and OFF respectively to stop the light emission of the discharge tube 33. At the same instant, a transistor 89 goes ON to apply the light emission stop signal through the output transistor 91 and transistor 105 of one shot to the terminal C1 which in turn lets the LED or the like flicker. Thus the dimming is checked without intricating the constitution such as increasing of the number of terminals.

Filed: 1987-03-28
Abstract: PURPOSE:To increase the ink-replenishment speed, to enable the enhancement of a recording speed, and to minimize the possibility of sucking bubbles, by providing a by-path connecting from an ink supply path to a pressure- propagation path through a check-valve. CONSTITUTION:A pressure-propagation path 13 is disposed horizontally, and a vertical part 15a of an ink supply path 15 and a vertical flow path 17 forming a by-path are arranged vertically. A pulse-form electric signal is intermittently applied to an electromechanical transducer 16 which is composed of a piezoelectric element, etc. and stuck on the back outer wall surface forming a pressure chamber 14, whereby a pressure wave occurs in the pressure chamber 14. This pressure wave is transferred to an orifice 11 through the pressure-propagation path 13, thus from here breaking through an ink reservoir 12 in front to make an ink drip jet. Due to the negative pressure generated in the pressure chamber 14 just after the jetting of the ink drip, ink is sucked from the ink reservoir 12 into the pressure-propagation path 13 through the orifice 11. Ink is supplied by the shortage of ink in the ink reservoir 12 due to the capillary force of an ink supply path 25 in the peripheral part.
