Patent JP-H0194389-A (JP)
Title: Driving of active matrix type liquid crystal display device
Inventor: MORIYAMA HIROAKI
IPC: G02F1/133
Filed: 1987-10-06
Abstract: PURPOSE: To solve a problem that the brightness of a selected pixel with slow timing is darker than that of a pixel with fast timing and flicker is easily generated by almost removing a change in the voltage of a display electrode at the time of inverting signal voltage. CONSTITUTION: The polarity of signal voltage to the potential Vc of a counter electrode is alternately inverted between odd-th signal lines and even-th signal lines to impress the voltage to the signal lines. In the case of alternately inverting the polarity of signal voltage values Vd1 to Vd2 K in each line, the voltage change ΔVpij of the display electrode is sharply reduced almost to zero. Namely the potential change of display electrode due to parasitic capacity between adjacent signal lines is mutually offset by mutually inverting the polarity of driving voltage of adjacent signal lines. Consequently a problem that the brightness of a selected pixel with slow timing is darker than that of a selected pixel with fast timing and flicker is easily generated is solved.

IPC: C12N15/09
Filed: 1992-09-22
Abstract: PURPOSE:To obtain an improving method in which problem of reassociation of a nucleic acid is eliminated, mainly in a hybridization reaction in a liquid phase method. CONSTITUTION:In a method for detecting existence of target arrangement in a nucleic acid sample by examining whether hybridization reaction of nucleic acid with a probe exists or not, this method for detecting nucleic acid is characterized by, as necessary, denaturing the nucleic acid in the sample from double- stranded chain to simple-stranded chain, carrying out nucleic hybridization reaction under conditions where other nucleotide chain having a sequence complementary to either one nucleotide chain having target sequence which exists as a nucleic acid sample is substantially fewer than either one nucleotide chain or the nucleotide chain does not exist.

Title: Low nox burner
Inventor: TAKESHITA SHIRO
IPC: F23D14/62
Filed: 1990-09-21
Abstract: PURPOSE:To reduce NOx in the exhaust gas and prevent the backfire of the flame to the outlet of a mixture gas channel by providing an air intake port which is provided in a second mixture gas chamber and sets the ratio of primary air ratio in it and in the mixture gas channel a guide plate which deflects the flow of the mixture gas blown out of said channel to the side of an air intake port. CONSTITUTION:A mixture gas that enters a second mixture gas chamber 12 from a mixture gas channel 11 and an air intake port 16 and part of secondary air are forcibly mixed by a guide plate 10. With this arrangement not only in the case of the maximum combustion quantity but also at the time of minimum combustion with a low flow rate the mixing is promoted sufficiently, and the mixture gas that flows out from a second burner port section 15 can be made a uniform mixture gas that is below the limit of combustibility, and as a result it is possible to prevent the flame from going back to the outlet of the mixture gas channel 11 through the second mixture gas chamber 12. And, the mixture gas with a low oxygen concentration which is blown out from the second burner port section 15 and not yet burned is supplied to the flame formed above a first flame hole section 9 and the combustion reaction becomes slow and the flame temperature falls. With this arrangement the generation of thermal NOx is reduced.

Title: X-ray tomographing device
Inventor: UMADATE HARUHISA
IPC: A61B6/00
Filed: 1988-10-07
Abstract: PURPOSE:To obtain an X-ray film image of excellent picture quality by arranging a sheet type X-ray absorbing member between a rear intensifying screen and a rear pressure plate so that the member is freely inserted and extracted. CONSTITUTION:When a photograph is taken, an unexposed film F is set between a front intensifying screen 3 and a rear intensifying screen 4 by a supply roll 12 from a supply magazine 13 while the front intensifying screen 3, the rear intensifying screen 4, and a thin lead plate 5 are on an optical axis. Then the rear pressure plate 6 moves toward a front pressure plate 2 to bring the film F between the intensifying screens 3 and 4 in contact, and X rays from an X-ray tube 1 are projected to photograph a transmission image of a subject P on the film F. The X-ray exposure in the photography is performed in a short time, but the dosage is large, so some of the X rays are absorbed by the rear thin lead plate 5, but the remaining transmitted X rays are scattered by the rear pressure plate 6. The scattered light which returns to the film F is absorbed by the thin lead plate 5. Consequently, the X-ray image of good picture quality is obtained.

Title: Method and apparatus for measuring voltage between two objects
Inventor: ROBAATO CHIYAARUSU MIRAA
IPC: G01R13/34
Filed: 1989-09-28
Abstract: PURPOSE: To measure the voltage between two objects accurately by using an electrooptical crystal that exposes birefringence at two cross axes that cross a light axis for connecting two objects in response to an electric field. CONSTITUTION: Parallel light beams 5 and 13 become polarization beams 5p and 13p by a first polarizer 7 and pass through a KDP crystal 3 in parallel with Z axis. With the passed polarization beams 5p and 13p, one polarization beam is delayed by the other polarization beam by fraction wave plates 11 and 15. The delayed polarization beam passes through a second polarizer 9. The output of the second polarizer 9 is converted to a phase-shift signal and an output signal indicating the voltage between two objects is generated based on the two phase-shift signals.

Title: Linear polarized light generator and liquid crystal projector
Inventor: NAKAYAMA MITSUO
IPC: G03B21/00
Filed: 1990-09-21
Abstract: PURPOSE:To obtain linear polarized light beams having uniform axes of polarization efficiently by rotating the axis of polarization of light, passed through a polarization beam splitter plate which has its normal slanted to incident light by an angle of polarization, by 90 deg. and reflecting the light to the same direction as light reflected by the polarization beam splitter plate. CONSTITUTION:When light 73 whose axis of polarization is not uniform is made incident on this linear polarized light generator, only the (s) wave 76 is reflected downward by a plate type beam splitter 70 and the (p) wave (and part of the (s) wave) passes through the beam splitter 70. A rotary polarizing plate 71 rotates the plane of polarization of the light 74 (consisting nearly of the (p) wave parallel to the incidence surface of the beam splitter) passed through this beam splitter 70 by 90 deg.. Therefore, the majority of the light 75 passed through the rotary polarizing plate 71 is the (s) wave and this light 75 is reflected by a total reflecting mirror 72 to the same direction with the reflecting plate 76 of the beam splitter 70 (reflected light 77). Consequently, linear polarized light beams which have uniform axes of polarization can be extracted from the light of a light source whose polarization axis is not uniform at a maximum and the utilization efficiency of the light source can be improved.
