Title: Method and device for inspecting defect or foreign matter
Inventor: NOGUCHI MINORU
IPC: G01N21/956
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To detect only substantially harmful foreign matter in a discriminating manner from the pattern by detecting the reflected light from the pattern by the illumination through an objective lens and a collimator lens, and comparing the image signal with the reference image signal. SOLUTION: Foreign matter 81, 82, a pattern defect 83, edge parts 84, 184 of the normal pattern, corner parts 85, 185 of the normal pattern, and fine normal patterns 85,185 are present on rectils 6, 106. Because the foreign matter 82 is fine, it scatters or refracts the light more compared with the edge part of the normal pattern. The detected signal at the positions 80, 180 by the transmitted light becomes the strong output at the corner part of the foreign matter part. If the output is binarized, the foreign matter 81, 82 can be detected in a discriminating manner from the edge part 84 and the corner part 86 of the pattern. The detected signal of the rectil 6 to be inspected and the detected signal of the standard inspection rectil 106 are taken in to obtain the absolute value of the difference between two signals by a comparison circuit.

Title: Liquid crystal display element
Inventor: UMEHARA YOSHITAKA
IPC: G02F1/1335
Filed: 1988-03-12
Abstract: PURPOSE:To suppress the degradation of light transmittance and to obtain a reflection type LCD of a good contrast at a low cost by providing prescribed colored thin-film pieces to one sheet of upper and lower electrodes or polarizing plates to many dot shapes. CONSTITUTION:The many colored thin-film pieces 5 in the dot shapes are provided on the rear face of a lower glass substrate 3 of a liquid crystal cell 1. The thin-film pieces 5 are formed by printing chromatic ink having light transmittability to the dot shapes and are formed in the form of microdisks. The incident light on this LCD is reflected by a light reflecting plate 8 and the light past the regions where voltages are not impressed is visually observed as a background color without being shielded by the polarizing plate 6. Since this light contains much of the light past the thin-film piece 5 and is made colored and, in addition, a spacing 12 is assured, the light transmittance does not lower. The light-transmitted video of the voltage-impressed region is, therefore, displayed on the bright background and the reflection type LCD of the good display contrast is inexpensively obtd.

Filed: 1990-03-08
Abstract: PURPOSE:To simultaneously measure the reactions of an extremely small amount of two or more liquid samples with good reproducibility and high accuracy and to achieve miniaturization and wt. reduction by simultaneously using a plurality of piezoelectric vibrators arranged so as to be brought into contact with a liquid on the single sides thereof. CONSTITUTION:A plurality of quartz vibrators 1 - 1n' having sample cells 2 - 2n' so mounted on the single surfaces thereof as to be in contact with a liquid are so arranged as piezoelectric vibrators as to be into contact with a thermo stat 3 to be connected to oscillation circuits 4 - 4n'. The surfaces of the vibrators 1 1n' generate minute vibration by the oscillation of the circuits 4 - 4'. Therefore, when the liquid comes into contact with the surfaces of the vibrators 1 - 1n', vibration receives effect and resonance resistance changes and the current flowing to the vibrators 1 - 1n' changes. This current is detected as the change of the amplitude of AC voltage by detectors 5 - 5n' to be inputted to a microcomputer 7 through an A/D converter 6 and the volume of a sub stance due to the viscosity change of the liquid and the adsorption and sedimen tation of the substance is measured. By this method, the extremely rapid change of reaction can be measured.

Title: Dc bias circuit
Inventor: FUJIWARA HIROYUKI
IPC: H03F1/30
Filed: 1991-03-22
Abstract: PURPOSE:To prevent an output voltage from being fluctuated even when a temperature fluctuation takes place by using an adder and a switching transistor(TR) having a same temperature characteristic as a switching TR for bias voltage switching. CONSTITUTION:When a switching TR 1 is turned on and a switching TR 2 is turned off by bias voltage control information fed from terminals 15,16, a collector voltage of the TR 1 reaches a collector-emitter saturation voltage VCE of the TR 1 and a collector V of the TR 2 is a voltage resulting from a positive power supply voltage divided by resistors 5, 6. When a TR 7 is always turned on, the emitter voltage of the TR 7 reaches a collector-emitter saturation voltage of the TR 7, but since the TR 7 is operated by a negative power supply, the voltage reaches a negative voltage -VCE. When the voltages are added by an adder 9, the collector-emitter saturation voltages of the TRs 1,7 are cancelled together.
