Title: Elimination method of sand, scum or lees in pump room
Inventor: MIYAUCHI SUNAO
IPC: E03F5/22
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To prevent the accumulation of a large amount of sand, etc., on the bottom of an inlet channel by elapse. SOLUTION: When sand, etc., S are accumulated to a certain extent on a bottom 2A of an inlet channel 2, an inlet gate 3 is closed to store water in an inlet canal 4, and when the water level is raised up to the specific water level WL, the inlet gate 3 is opened to wash away the sand, etc., S on the bottom 2A into water absorption tanks 5 and 5 by suddenly discharging water in the inlet canal 4 to the inlet channel 2. Even if this sand elimination control is executed, when the sand, etc., S remain in the inlet channel 2 or when inlet volume of water to the inlet canal 4 is less than before, after water discharged into a drain pipe 8 is stored in a tank 9, the inlet gate 3 is closed to suddenly discharge water stored in the tank 9 into the inlet channel 2, and the sand, etc., S remaining in the inlet channel is washed away toward the water absorption tanks 5 and 5.

IPC: H05B41/24
Filed: 1991-09-30
Abstract: PURPOSE:To restart oscillation of an inverter immediately after a load abnormal state is canceled by shortcircuiting both ends of the switching element of a holding circuit according to the detection outputs of a circuit for detecting the cut-off of a DC power source. CONSTITUTION:When abnormal lamp voltage is detected by an abnormality detection circuit 17, an oscillation stopping circuit 12 and a holding circuit 14 operate and the output of a base current source is indirectly released and oscillation of switching transistors 5, 6 is stopped and this oscillation stopped state is held by the holding circuit 14 for the duration of power supply. When the power is turned off for the replacement of lamps, the divided voltage of a voltage dividing circuit 18 is lowered and a reset circuit 19 operates and both ends of the holding circuit 14 are shortcircuited. With this constitution, when the power is turned on after the replacement of lamps, oscillation is immediately restarted and a discharge lamp 15 can be lighted and the not-turn- on of the discharge lamp 15 due to the influence of residual charge remaining in the switching element of the holding circuit 14 after the power is on, can be prevented.

Filed: 1984-11-30
Abstract: PURPOSE:To improve the earthquake-proof property of the titled supporting frame member as well as to secure the simplicity of maintenance inspection by a method wherein an auxiliary member is provided in stretched form at vacant space. CONSTITUTION:As a supporting frame member 13 has a cantilever structure, it vibrates in horizontal direction when the exciting force in horizontal direction 18 is at work, and there is the possibility of generation of phenomenon such as the breaking and the like of an insulating terminal 12 due to the deformation of a cable connection box 10. However, said deformation can be prevented by the deposition of a member 16, and the improvement in earthquake-resisting strength can be accomplished by a simple structure. Also, when a plate-like material is used as the member 16, it can be utilized as a foot board for inspection and the foot board for work when a maintenance inspection, a repair work and the like are performed on the insulating terminal 12, the cable connection box, or their circumferential part. Accordingly, the maintenance inspection can be performed easily, the time required for assembling of the foot board for work can be reduced, and the safety in the work performed at elevated place can also be secured.

Title: Detection of surface defect
Inventor: YAMAUCHI HIDEO
IPC: G01N21/89
Filed: 1989-09-29
Abstract: PURPOSE:To discriminate between the flaw and inherent defect on the surface of an object to be inspected in a comparatively easy manner by detecting a part of the mirror surface reflected beam from the surface of the object to be inspected by a detector along with the scattering beam component due to the defect. CONSTITUTION:The laser beam 2 emitted from a laser beam source 1 irradiates the surface 5 of an object to be inspected by a mirror 3 and a condensing lens 4. A visual field limiting element 11 excludes a part of the mirror surface reflected beam 6 from the surface 5 of the object to be inspected and the remaining mirror surface reflected beam 7 is detected by a detector 10 along with the scattering beam 9 due to the defect 8 present on the surface 5 of the object to be inspected. The position of the visual field limiting element 11 is controlled so that 20 - 80% of the quantity of the mirror surface reflected beam from the surface 5 of the object to be inspected is detected by the detector 10. By this constitution, the flaw and protruding defect 8 on the surface 5 of the object to be inspected can be discriminated in a relatively easy manner without applying fast operational processing to the output waveform obtained by the detector 10.

Title: Image processing unit
Inventor: SATO YUMI
IPC: G03G21/04
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for entry of user information again after processing start or after reservation by storing user identification information and reading it as required so as to continue the operation. SOLUTION: When a card number of a magnetic card from a card reader 7 is in existence in registered card number information stored in a decoder main body 30, a department number is stored in panel data corresponding to a panel data number to be assigned and a processing start request including the department number is sent to the decoder main body 30. The decoder main body 30 executes the processing. When the processing is interrupted due to paper shortage or jamming or the like and there is any executionable processing, the execution is instructed. When a release notice of a stagnation cause is received from the decoder main body 30, the department number information is acquired from the corresponding panel data and a processing consecutive request with the department number set thereto is sent to the decoder main body 30.  Thus, when the processing is interrupted on the way, the processing is restarted without the card.

Title: Line noise superposing circuit
Inventor: ONO MASAHIKO
IPC: H04B3/46
Filed: 1986-10-23
Abstract: PURPOSE:To enable a power amplifier which operates with a low source voltage to be used by applying a noise to a transmission line through a couple of amplifying means which perform mutually differential operation and has high output impedance. CONSTITUTION:The noise input is supplied to an inverter 9 through a level shifting circuit 8 and inverted in polarity. The operational amplifiers 14 and 16 operate differentially and the noise current flows in the order of a positive power source terminal VC, resistance 12, a PNP transistor(TR) 15, a line output terminal OUT1, a line, a line output terminal OUT2, an NPN TR 17, a resistance 13, and a negative power source terminal VE. The level shifting circuit 8 makes it secure that the collector potential of the TR 15 is higher than the collector potential of the TR 17. Both voltage follower circuits 10 and 11 are high in output impedance, so a sent signal never enters this line noise superposing circuit.

The substrate temperature is then set at 450 deg.C and trimethyl gallium is fed into the reaction furnace together with arsine thus growing a GaAs butter layer by 50nm thick or less. Annealing is then conducted with the substrate temperature being set in the range of 700-800 deg.C. Subsequently, trimethyl gallium and arsine are fed to epitaxially grow a III-V compound semiconductor, i.e., a GaAs single crystal. This method eliminates troubles, e.g. falling of substances adhering to the inside of furnace and mechanical malfunction of the system, and produces a high quality compound semiconductor stably.
