Title: Phase modulator
Inventor: SHIMIZU RYOTARO
IPC: G02F1/01
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a phase modulator easy to assemble and capable of obtaining uniform vibration. SOLUTION: A phase modulator having a piezoelectric element fixed thereto through a vibration absorbing member is unstable in vibration when there is positional shift. The vibration absorbing member 1 has a plurality of radial arm parts 2 extending outward from the center point or a small circumference thereof integrally formed thereto and the respective radial arm parts 2 are allowed to cross the piezoelectric element 3 so that the axis of the piezoelectric element 3 coincides with the center of the vibration absorbing member to arrange the vibration absorbing members 1 on both sides of the axial direction of the piezoelectric element 3. Therefore, assembling is easy and thereis no positional shift.

IPC: H04N9/74
Filed: 1987-06-26
Abstract: PURPOSE:To obtain a natural composite image by equalizing the color signal level of a main image to the color signal level of a subordinate image. CONSTITUTION:A color burst signal contained in the composite video signal of the main image and a color burst signal contained in the composite video signal constituting the subordinate image are fetched from 1st and 2nd burst gate circuit 36 and 37 and applied to a comparator 38 respectively.

Title: Detection of flaw of glass bottle
Inventor: SATOU SHIGEO
IPC: G01N21/90
Filed: 1982-09-14
Abstract: PURPOSE:To enable the sure detection of flaw intensity at relatively a low cost by placing a light projector and a photodetector in the same plane position and in the plane position roughly perpendicular to the transfer direction of a bottle, detecting the flaw intensity for about half circumference by the transfer of the bottle and deciding the flaw intensity when the peak value of the detected value exceeds a reference value. CONSTITUTION:A light projector 3 which irradiates light to the flawed part of a bottle 2 transferred in the direction shown by an arrow in the figure by a transfer device 1 from one or more light sources thereof and a photodetector 4 which detects the light scattered from the flawed part of the bottle 2 are disposed within roughly the same plane at the angle alpha of the respective optical axes and in such a way that both are positioned roughly perpendicular to the transfer direction of the bottle. The photodetector 4 receives the light scattered from the flawed part of the bottle 2 as its optical axis. Said scattered light as the optical axis is captured by lenses 10, 11, and the photodetected luminous flux through a slit 12 is detected by a photodetector 13 as the voltage (or current) signal corresponding to light intensity. Said signal is amplified up to a suitable level with an amplifier circuit 14 and is subjected to comparative decision with a reference value for comparison by a comparing decision circuit 15.

Title: Color cathode-ray tube device
Inventor: YAMAGUCHI TAKEHIRO
IPC: H01J29/76
Filed: 1985-07-19
Abstract: PURPOSE:To improve the convergence of a color cahtode-ray tube device by reducing the production of an eddy current resulting from a magnetic flux leaking out from a deflection york by providing the shielding member with a slit which is continuous with the hole of the shielding member and opens a closed circuit formed around said hole through which a magnetic flux leading out from the deflection york passes. CONSTITUTION:A shielding member 8 has a penetrating hole 10 and a slit 11 through which a magnetic flux leaking out from a deflection york frequently passes. The hole 10 and the slit 11 open the closed circuit formed by the shielding member 8 surrounding the hole 10 and prevent an overcurrent from flowing through the closed circuit. Due to the hole 10 and the slit 11, an eddy current produced by the magnetic flux leaking out from the deflection york is significantly reduced. Consequently, the disturbance of convergence resulting from the overcurrent is significantly alleviated.

IPC: H01L29/739
Filed: 1993-06-30
Abstract: PURPOSE:To reduce the expansion of space between equivalent electric field limiting rings and prevent the drop in breakdown strength by making a construction in a manner that there will exist a position to minimize the space to the utmost between adjoining electric field limiting rings, out of the main surface part of the semiconductor substrate. CONSTITUTION:A circular p<+> type layer 16 formed on the bottom of a circular groove 12a functions as an electric field to enhance the expansion of a depletion layer which is to be formed when a p-n joint between an n<-> type layer 14 and a p<+> type layer 15 is reverse-biased. Since the layer 16 is formed on the bottom of the groove 12a, the part in which the rings 16 are most close to each other is located away from the main surface 12 of the other. Therefore, even if any positive charge would be generated due to moving ions in the outer part of a semiconductor substrate 1 through a high-temperature bias test, the carrier density of the layer 14 in the part where the rings 16 are most close to each other is given no influence and the breakdown strength hardly drops.

Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To provide an improved method for detecting errors and decoding and processing messages by executing a function based on the data of a post- correction data part, corresponding to error detection and zero value detection. SOLUTION: An error detector 174 reads a CRC error mark word and judges whether or not the error is present inside a post-correction CAC information unit. In the case that the error is not in it, the post-correction CAC information unit is specified as a 'good' unit, sent to a layer 1 processor 166 and processed further. Thus, a layer 3 processor 170 of a microprocessor 132 processes the function, based on the data of the post-correction CAC information unit. Further, the error detector 174 judges whether or not the entire BCH syndrome corresponding to the post-correction CAC data part of practically important data is zero. Then, correction is executed only for the post-correction CAC data part judged as being provided with a non-zero BCH syndrome by the error detector 174.
