Title: Automatic voltage regulating device
Inventor: TANIGUCHI MASAMITSU
IPC: H02P9/14
Filed: 1979-07-03
Abstract: PURPOSE:To improve responsiveness without the necessity of smoothing filter by inputting armature voltage of synchronous machine and controlling field voltage by the difference between the sum of square-law circuit providing output proportional to the square of each phase and reference voltage value. CONSTITUTION:Voltage at armature 1 of synchronous machine is converted to proper level by means of auxiliary transformer 7. Each phase of its secondary side is connected to square-law circuit 17 generating output proportional to the square of input. Then the difference between the sum of output at square-law circuit 17 and reference voltage is amplified by arithmetic amplifier 16 and supplied to excitation apparatus 6. As the voltage at the armature of synchronous machine is converted from the set value of reference voltage, the sum of square-law circuit 17 varies, generating differential voltage. It controls field winding 2 of synchronous machine through the intermediary of excitation device 6. Consequently, it is possible to dispense with the insertion of smoothing filter for removing ripple component and thus to eliminate the delay in response time.

IPC: G03B42/02
Filed: 1982-05-19
Abstract: PURPOSE:To obtain easily homogeneous reproduced pictures repeatedly, by using a storage type phosphor, where a radiation picture is recorded, over and over cyclically. CONSTITUTION:A storage type phosphor plate 2 is stopped in the position facing a radiation source 5, and a transmission radiation picture of an object 6 is stored and recorded. The storage type phosphor plate 2 is stopped in the position facing an optical deflector 8, a photodetector 9, etc. and is scanned with the excitation light emitted from an excitation light source 7 and emits a light acceleratingly in accordance with stored and recorded picture information, and this light is inputted to the photodetector 9 through a light transmitting means 10, and an electric picture signal corresponding to the radiation picture is outputted. When the picture is read, the phosphor plate is stopped in the position facing an erasing light source 11, and the formed radiation picture is erased, and the phosphor plate 2 is restored to the reusable state. In this method, what differs from the method, where phosphor plates are carried one by one, is the fact that the risk of the damage of the storage type phosphor plate 2 is almost removed, and homogeneous reproduced pictures without the variance due to sheets are obtained because the phosphor plate 2 is always used over and over cyclically in a certain order.

Title: Counterrcurrent evaporating heat exchanger
Inventor: EDOWAADO ENU SHINNAA
IPC: F28D5/02
Filed: 1979-07-05
Abstract: A counterflow evaporative heat exchanger comprises a vertical conduit (10) in which a coil assembly (16) is positioned. A fluid to be cooled or condensed passes through the coil assembly (16) while water is sprayed downwardly over it and air is blown upwardly through it. The coil assembly (16) comprises a plurality of tubes (66) which at each level in the assembly are spaced apart from each other in the horizontal direction by an amount greater than the diameter of the tubes. This has been found to improve heat transfer in comparison to counterflow evaporative heat exchangers using closely packed coil assemblies.

Abstract: PURPOSE:To allow the irradiation of electronic parts with a laser beam without exerting an adverse influence thereon even in the narrow place of the electronic parts by mounting an exit optical part to a movable block in the state in which the optical axis thereof intersects orthogonally with a supporting bar when viewed from the side face, thereby constituting the above device. CONSTITUTION:A printed circuit board 22 is irradiated with the laser beam 6X from the exit optical part 6 in the state orthogonal with the circuit board, by which a lead 25 is soldered to the circuit patterns. The exit optical part 6 is mounted to the movable block 13 in this case. This movable block 13 is moved within an X-Y plane by a motor, etc., by which the laser beam 6X emitted from the exit optical part 6 is scanned along the length of the supporting bar 9. The laser beam 6X is condensed at a certain contracting angle in the emission of this laser beam and the sectional shape of the supporting bar 9 is determined by nearly the same angle as the condensing angle. Therefore, the electronic part 23, 24 are consequently soldered without interference with the laser beam 6X even if the spacing between these parts is small.
