Title: Single phase direct firing transistor inverter
Inventor: TOMITA AKIRA
IPC: H02M7/5387
Filed: 1982-05-21
Abstract: PURPOSE:To reduce the noise of an output wave of a transistor inverter without using a modulation wave system by providing a sinusoidal wave oscillator and an AC decomposed sinusoidal pulsating wave converter to fire each driver transistor of the inverter. CONSTITUTION:A single phase AC power source F voltage is rectified by a rectifier BG2, applied through a voltage regulator to an inverter having transistors Tr11-Tr14, and converted into single phase AC. Further, a variable sinusoidal wave oscillator 1 is provided, the output of the oscillator 1 is supplied to an AC decomposed sinusoidal pulsating wave converter 2, a positive current is produced via transistors Tr1, Tr2 and negative current is produced via transistor Tr3, Tr4 to obtain two outputs of 180 deg. of phase difference through photocouplers PC1, PC2, and the firing of the transistors Tr11-Tr14 are controlled with the voltage-raised signals D, E. Accordingly, since the firing is performed without the modulation wave, noise is less contained in the output, and the noise in a load motor or the like can be prevented.

Title: Boiling water reactor
Inventor: FUJII TADASHI
IPC: G21C15/02
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To improve operability and safety by welding a mirror plate of a shroud head directly to a flange of it and setting the height from the top end of grid guide to that of a core shroud at 4.5 to 5.5 times as long as the distance between inner faces of a channel box for a fuel assembly to reduce an upper plenum area without impairing a function of mixing water with steam. SOLUTION: A top grid guide 5 is placed above an installation seat 22, and a wedge 23 of a supporting member restrains the lateral slippage of it. In a shroud head 4, a rim body is deleted and the height is lowered by welding a mirror plate directly to a flange 17. Moreover, the height from the top end of the top grid guide 5 to that of a flange 16 of a core shroud is set at about 5 times of the distance between inner faces of a channel box to lower the height. Notably, a water injection nozzle 25 is placed diagonally below to a level surface which passes through the center line of a header pipe 24 to constrain the increase in the height of a core water injection system as a whole.

Title: Method for single crystal growth
Inventor: TAKAHASHI MICHIO
IPC: C30B29/40
Filed: 1986-04-15
Abstract: PURPOSE:When a single crystal of III-V compound semiconductor is allowed to grow by the liquid-sealed pulling-up method, the growing single crystal ingot is irradiated with X-ray on its surface and the Brag's reflection is monitored to effect early detection of crystal defects to increase the yield of single crystals. CONSTITUTION:When a single crystal of III-V compound such as GaAs is pulled up from the polycrystalline melt 16, the melt is sealed with a sealant such as diboron trioxide 17, the seed crystal 18 of GaAs is dipped and gradually pulled up to allow the single crystal of GaAs to grow on the end. At this time, X-ray beam is projected to the surface of the single crystal 19 in the sealant 17 to monitor the Brag's reflection with the detector 26. When the crystal defects such as poli, twin or the like are detected, the defect parts are melted again in the GaAs melt and pulled up again. Thus, single crystals of III-V compound semiconductor such as GaAs of good quality is always obtained with extremely reduced defects.

Inventor: MURAOKA YOSHITAKA
IPC: G06T5/00
Filed: 1983-05-16
Abstract: PURPOSE:To obtain the sampled data of high reliability by sampling each picture data by plural sampling pulse trains of the same frequency and different phases and deciding by majority the sampling information of each pulse train to collect these information into one piece of information. CONSTITUTION:A reference sampling pulse is produced from a source pulse generator 2, and each phase of these pulses are delayed by subordinate pulse generators 3a and 3b.

Each sampled data undergoes the majority decision through a majority deciding circuit 4, and the result of this decision is latched by a D flip-flop FF4 in the form of the input data on cycle.

Title: Thin film transistor type liquid crystal display device
Inventor: OGURA SHIGEKI
IPC: G02F1/133
Filed: 1991-04-17
Abstract: PURPOSE:To prevent the light leak and deterioration of liquid crystal of a thin film transistor(TFT) type liquid crystal display by eliminating a DC component between a drain electrode and a counter electrode. CONSTITUTION:A shield electrode 7 is formed on the drain electrode 2 of a TFT across an insulating film. The shield electrode 7 is connected electrically to the counter electrode. Consequently, the shield electrode 7 and counter electrode are disconnected electrically by the shield electrode 6, so no DC component is generated between them. The liquid crystal on the drain electrode, therefore, does not turn ON so no light leak is caused. Further, no DC component is impressed to the liquid crystal, so the liquid crystal does not deteriorates.

Title: Optical disk and optical disk device
Inventor: NAGASAWA MASAHITO
IPC: G11B7/24082
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity for switching tracking systems during seek operation by arranging wobbled pits or grooves in the head section of each sector of the recordable area and the reproduction-only area. SOLUTION: In the sectors 2, 5 of the RAM section, the address section 3 where grooves are wobbled represents the sector address. In this case, however, the wobbled groove is set so as to be displaced each in the disk direction by 1/2 against the groove width. Like this, by wobbling the groove different sector addresses can be obtained at the time of land scanning in the RAM section as well as at the time of groove scanning. In addition, tracking offset can be corrected by comparing the levels of the respective reproduction signals from the grooves(or lands) wobbled to, e.g. the inner and outer periphery sides.

Title: Inspection apparatus
Inventor: TSUDA MUNETAKA
IPC: A61B5/055
Filed: 1983-05-18
Abstract: PURPOSE:To make it possible to uniformly detect the spin density distribution of an object to be inspected, by holding constant difference between the resonance frequency of nuclear spin generating a resonance phenomenon in a uniform magnetic field and the frequency of a high frequency magnetic field while allowing the center frequency of the high frequency magnetic field to sweep throughout the object to be insepcted. CONSTITUTION:NMRs (nuclear magnetic resonance signals) of which the phases are mutually shifted by 90 deg. are accumulated to an adder 23 while converted to digital amounts by A/D converters 21, 22. The signal from said adder 23 is subjected to Fourier transform by a calculator to be converted to a signal of a frequency component from signal of time response. This signal shows the spin density of the moisture of an object to be inspected projected to the vertical direction of an oblique magnetic field when the NMR signals are measured. A function generator 6 is controlled so as to rotate the oblique magnetic field at a certain angle around the center axis of the object to be inspected to perform measurement for obtaining a new projected image. When a series of measurements are finished, image re-constituting operation similar to X-ray CT is performed from a plurality of projected images and the result is stored in the memory of the calculator and displayed by display 24. By sweeping throughout the object to be inspected by the center frequency of a high frequency magnetic field, the spin density distribution of the object to be inspected can be uniformly detected.

Title: Manufacture of plate for lead-acid battery
Inventor: YOSHINAKA MINORU
IPC: H01M50/541
Filed: 1987-04-08
Abstract: PURPOSE:To prevent the scatter of lead oxide dust and to reduce the generation of welding defectives by masking an electrically connecting part with an insulating, acid resistant material, conducting formation, removing the masking material after formation, and electrically connecting the masking removed part. CONSTITUTION:In an unformed plate using an expanded grid, the part to be electrically connected when a battery is assembled is masked with an insulating, acid resistant material before formation. After formation, the masking material in the masked part 1 is removed, and electrical connection is done in the masking removed part 4 when a battery is assembled. Since the part to be electrically connected is masked, an oxide film 3 does not form there during formation, and by removing the masking material in the masked part 1 after formation, the surface suitable for welding can be ensured there. Therefore, the scatter of lead oxide dust produced by removing the oxide film does not arise and environmental sanitation is remarkably increased.
