Filed: 1985-03-15
Abstract: PURPOSE:To obtain a matrix type liquid crystal color display device having a wide color reproduction range without deviating to a specific color by using color filters of which the thicknesses and areas vary with colors. CONSTITUTION:The matrix type liquid crystal color display device is constituted of the red, green and blue color filters 1a-1c, transparent electrodes 2, 3, a liquid crystal 4, transparent substrates 5, 6, polarizing plates 7, 8 and a sealing member 9.

The transmittance in the non-selection stage is thus made low with respective colors and the color reproduction range in the stage of color mixing is widened. The difference in the transmittances and color purity of the filters owing to the differences in the thicknesses is compensated and the deviation in the color reproduction range in the stage of color mixing is eliminated if the display device is made into the constitution to change the areas of the color filters with each of the colors.

Title: Oblique angle flaw detection method and apparatus
Inventor: KOGA KAZUNORI
IPC: G01N29/04
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To reduce the noise at a specific position like the reflected wave from a non-objective while enhancing only the intensity of the reflected wave from an objective and to enhance the relative SN ratio of a detection signal in oblique flaw detection. SOLUTION: Time shift quantity is set corresponding to the relative position of a probe 14 and a flaw 21 so that the phase only of the reflected wave from an object 20 to be inspected is matched with the same phase. The waveform operational processing of the mutual receiving signals at respective positions having this time shift quantity is executed by a waveform data operation part 6 to increase the intensity only of the reflected wave from the object. Since the phases of the receiving signals at the respective positions are different in the reflected wave from a non-objective, the intensity thereof is lowered by this waveform operational processing. By this constitution, the relative SN ratio of a detection signal can be enhanced in oblique angle flaw detection and the minute flaw of a welded part can be detected.
