Patent JP-S5577377-A (JP)
Title: Protector for inverter
Inventor: MIYAZAWA YOSHIAKI
IPC: H02M7/515
Filed: 1978-12-06
Abstract: PURPOSE: To prevent the main thyristors of an inverter from being damaged, by immediately detecting the magnetic saturation of an inverter transformer to turn on a short-circuit thyristor before the inverter fails to be commutated.  
     CONSTITUTION: The difference between the primary and secondary currents of an inverter transformer 6 is detected by a differential current detection circuit 43 to find out the magnetic saturation of the inverter transformer 6, which would cause an inverter 10 to fail to be commutated. As a result, a short-circuit thyristor 32 is turned on before the commutation failure takes place. The inverter 10 is thus protected.

IPC: H04L25/05
Filed: 1978-12-06
Abstract: PURPOSE:To make it pissible to accomplish data transmission of a terminal equipment without keeping data transmission at a low speed side in a queue by interrupting data transmission at a high speed side while the low-speed data transmission is in process. CONSTITUTION:Processing part 10 of a terminal equipment fulfilling low-speed and high-speed data transmission processes has micro-computer 30 and is connected to series-parallel interchange circuit 36 for low-speed data transmission and series- parallel interchange-circuit 38 for high-speed data transmission. On the basis of a clock generated by clock circuit 40, circuit 36 performs data transmission and reception to output transmission in-execution indication signal 44, indicating that low- speed data transmission is in process, to clock circuit 42. Further, the other circuit 38 performs data transmission and reception on the basis of a clock generated by circuit 42 under the control of signal 44. Consequently, the high-speed data transmission process is interrupted during the period of the low-speed data transmission, but the lowering of its transmission rate is extremely slight. Therefore, the high-speed transmission of data can be carried out.

Abstract: PROBLEM TO BE SOLVED: To prevent dew condensation and water leakage in the interior of a suspended ceiling by constructing of a double structure at least a part of the side surface of the suspended ceiling, serving as a blowoff opening of a cooler. SOLUTION: A cooler 3 is provided on the upper part of a car 1. Cold air blown off from the cooler 3 is sent to the inside of the car through a blowoff opening 8. A part of a suspended ceiling 5 serving as the blowoff opening 8 is provided with a cold air guide plate 9 for cold air blown off from the cooler 3, and a buffer space 10 is provided between the cold air guide plate 9 and the suspended ceiling 5.

IPC: G01N21/90
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To easily and accurately detect dust in accommodated liquid even in a container with a flat section. SOLUTION: A container 10 with a flat section is supported while it is inclined by a holder 20. With the holder 20, an upper end part is supported so that it can be rocked and moved in the direction of an axis of inclination L1 by a support means 30 and a lower end part is supported by a vibrating means 40. The vibrating means 40 vibrates up and down at the lower end part of the holder 40 so that a closed curve can be drawn. As a result, a traveling flow is generated in liquid 15 in the container 10, thus agitating the liquid 15. Also, on the liquid surface 15a, an eddy flow is generated along a semi-arc- shaped wall at both sides of the container 10, and dust gathers toward the center of the eddy flow. The dust is detected by an optical detection means 70.

Title: Charging method of image-forming device
Inventor: ANDOU YUUJIROU
IPC: H01T19/00
Filed: 1978-12-06
Abstract: PURPOSE: To make charging even by performing the operation starting or changing of charging capacity of the charger of an image-holding member such as photosensitive drum which is moving at varying speeds with a delay in timing than that at the speed chaging of said image-holding member.  
     CONSTITUTION: A transfer corona discharger 11, a destaticizing corona discharger 13, etc. are disposed around an insulation drum 9. Here, the surface potential of the insulation drum 9 is made to an even potential of about +50V by a discharger 13, thence the image part having been given ions by a screen 6 becomes of a potential of about -150V. Now, if the changing of the applied voltage of the transfer corona discharger 11 of the drum 9 and changing of the speed are simultaneously performed, the overcharged portions become +15V after the passage through the destaticizer 13, thus producing a potenial difference of 35V from the other 50V region. If as against this the changing of the applied voltage is slowed by 0.14 second than changing of the speed, the potential of the overcharged portions becomes 43V, producing a difference of only 7V with respect to the other 50V region, thus as compared to the foregoing potential difference of 35V, charging may be made considerably even.
