Title: Controller for revolution speed of atomizing head
Inventor: SAITOU SHIGEO
IPC: B05B5/04
Filed: 1980-08-26
Abstract: PURPOSE: To control the revolution speed of an atomizing head by a method wherein a revolution speed controlling part is provided in a passage for supplying air for driving an air motor which drives an atomizing head to rotate, a beam of light is projected to a reflecting surface of the rotating shaft of the motor, and the reflected light is transmitted to a light receiving member in the controlling part through an optical fiber.  
     CONSTITUTION: When air for driving is supplied from an air source to the air motor 2, the rotary shaft 2a starts rotating and the atomizing head 1 is also rotated. When a light-emitting element is turned ON, a beam of light is transmitted to the motor 2 through the optical fiber 14 and is projected onto the locus of the rotation of the reflecting plate 13. When the reflecting plate 13 is rotated with the rotary shaft 2a, the plate 13 reaches the position faced to a focusing part 14a of the optical fiber 14 at a frequency of once per one complete rotation of the shaft 2a, when the reflected light reaches a light receiving and amplifying device 9. With the revolution speed of the rotary shafts 2a thus detected, pneumatic pressure is controlled by an air servo device 6 to obtain a predetermined revolution speed for the atomizing head.

Title: Image output circuit device
Inventor: KATO TADASHI
IPC: A61B1/04
Filed: 1986-05-23
Abstract: PURPOSE:To always keep the phase position of a reading clock constant and to prevent a picture jitter from occurring by obtaining the phase lock of a picture element reading clock with a horizontal synchronizing signal. CONSTITUTION:When a horizontal synchronizing signal S1 and a frequency- dividing signal S2 are inputted to a phase comparator 12, the phase comparator 12 detects the phase error of the signals S1 and S2, and outputs a voltage signal to a VCO 13 in accordance with the phase error. The VOC 13 outputs the signal of a frequency to make the phase error into zero in accordance with a voltage signal. When a loop is in a phase locked condtition, the phase position of a picture element reading clock CLK and a frequency dividing output signal S2 is locked at the rise of the horizontal synchronizing signal S1. In such a way, the timing of the rise of the horizontal synchronizing signal S1 and the picture element reading clock CLK will not be coincident. Since the rise of the horizontal synchronizing signal and the picture element reading clock is not coincident, a picture jitter will never occur.

Title: Gate circuit of gate turn-off thyristor
Inventor: ONDA KENICHI
IPC: H03K17/04
Filed: 1978-09-27
Abstract: PURPOSE: To make it possible to reduce the loss of a gate circuit by emitting energy of a capacitor, a reactor, etc., which is stored by an off current flowing circuit, to turn off GTO.  
     CONSTITUTION: When transistor T 5  is conductive while a forward current is flowed to gate turn-off thyristor GTO, the GTO is turned off, and no current is flowed across the cathode and the gate of GTO, and the current is transferred from gate power source Eg to the circuit of T 5 , reactor L 2  and resistance R 5 . Next, when T 5  is turned off, a voltage is generated with the polarity as shown in the figure to flow a current across the gate and the cathode of GTO, and GTO is turned on. Since the current flowed to L 2  at this time is approximately 1/10 times as high as the conventional current, the power loss of R 5  is reduced considerably.

CONSTITUTION: When power 52 is turned on by a power switch 55, a current flows to an air core coil 16 for driving, and a magnetic field is generated in the direction of A. This magnetic field draws a core member 18, a permanent magnet 20, and a yoke 21 in direction A. At this time, an air core coil 16' for position detection detects the shifting into the air core coils 16 and 16' of a core member 18, and inputs this detected voltage into one terminal of a comparator 54. For the voltage inputted into the other of the comparator 54, the voltage applied to the air core coil 16 is fed back by a feedback resistor Rf. The output voltage of the comparator 54 at this time turns off the transistor 53 provided between the air core coil and a power source 52.  As a result, a core member 18, etc., return to the their places by the restorative force of a plate spring 17 working in the direction B. This operation is repeated, and reciprocation is performed, and it is transmitted to a carrier.
