Title: Optical device of photomagnetic storage device
Inventor: DEGUCHI TOSHIHISA
IPC: G02B27/28
Filed: 1983-11-08
Abstract: PURPOSE:To improve the quality and reliability of an optically reproduced signal by setting optical characteristics including the phases of a beam splitter, mirror, and analyzer in a specific state. CONSTITUTION:Laser light projected from a semiconductor laser 2 is passed through a collimator lens, molded prism 4, polarization beam splitter (PBS) 5, and reflecting prism 6 to make S-polarized light incident on a magnetic recording medium 1. Its reflected light travels back and is reflected by the PBS5 to enter photodetectors 11 and 12 through a PBS8, lambda/2 plate 10, spot lens 9, and PBS11. One light beam is incident on a photodetector 16 through a spot lens 14 and a cylindrical lens 16. The PBSs 5 and 8 are each provided with such a dielectric multilayered thin film that the coefficient rp of reflection to P-polarized light is larger than that rp to S-polarized light and the phase difference delta between the P and S waves in npi-pi/4<=delta<=npi+pi/4 (n: integer), thereby preventing deterioration in SN ratio. Thus, the quality and reliability of the optically reproduced signal are improved.

Title: Image reader
Inventor: KONAGAYA TATSUYA
IPC: H04N1/04
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To provide an image reader capable of preventing the occurrence of color smear caused by the generation of vibration. SOLUTION: When the vibration of an amplitude more than a prescribed value are detected at the time of image reading processing for continuously reading plural images while passing a long photographic film recording the plural images through a prescribed recording position by a film carrier, concerning this image reader, the operation of image reading processing is interrupted and a message showing such a state is displayed (steps 300 and 302). Then, it is discriminated whether the interrupted operation is image reading operation or not and when it is image reading operation, after the reading end position of an image read just before is located at a prescribed reading position by inversely carrying the photographic film, image reading operation is restarted by inverting the conveying direction of the photographic film again (steps 304-314).  Thus, the image read on the occurrence of vibration is read again.

Title: Surface acoustic wave resonator
Inventor: SAKAIRI NATSUHIKO
IPC: H03H9/25
Filed: 1991-08-23
Abstract: PURPOSE:To attain high frequency without narrowing an interval between electrodes by arranging reflection electrodes in a surface acoustic wave resonator like steps and setting up a level difference between adjacent steps to lambda/n (lambda is the average speed of surface acoustic waves propagated under electrodes). CONSTITUTION:Plural step-like reflection electrodes 3 are arranged between both the sides of a crossing finger-like electrode 1 for generating surface acoustic waves to form reflectors 2 in which each interval between the electrodes 3 is set up to lambda/2. Rectangular waves are used as surface acoustic waves to be made incident upon the electrodes 3 and the optical path difference of the reflected wave of each surface acoustic wave on each step becomes 2lambda/n because the level difference between adjacent steps is lambda/n, so that phases are shifted. When the reflected waves of these surface waves are synthesized, n times the higher harmonic of the incident surface acoustic wave is obtained. Plural reflectors 2 each of which uses plural electrodes 3 are arranged on both the sides of the electrode 1 to confine n times the higher harmonic. Thus the surface acoustic wave resonator whose center frequency is n times the frequency of an incident surface acoustic wave can be constituted of plural electrodes 3 arranged at lambda/2 intervals.

Abstract: PROBLEM TO BE SOLVED: To prevent the leakage of air for combustion into a furnace through a gap between both end parts of a stoker and a fireproof grate by sliding a side seal grate longitudinally together with a mobile grate while being put closely on the side of a side seal plate body. SOLUTION: A side seal plate body 29 is arranged on both side parts of a stoker S while being mounted on a fixed grate and a seal plate 31 free to expand is interposed at a gap between the side seal plate body 29 and refractory furnace wall F to seal the gap.

Title: Manufacture of surface acoustic wave device
Inventor: GOTO YOSHIHIRO
IPC: H03H9/08
Filed: 1985-09-24
Abstract: PURPOSE:To control and adjust the frequency of an SAW device with high accuracy by applying dry etching to a metallic thin film until the substrate is nearly exposed, applying wet etching to the metallic thin film left by the dry etching and forming an electrode while the cross section is clarified. CONSTITUTION:After a metallic thin film 2a such as Al is vapor-deposited to the substrate 1, a resist 4 is applied to the electrode forming part and the metallic thin film 2a is etched (the 1st stage etching) by applying dry etching by argon ion plasma. The etching is stopped before the background substrate 1 is exposed. Then the metallic thin film 2a left on the substrate 1 is etched by wet etching (the 2nd stage etching) for the removal. Since the wet etching is an isotropic etching, when over etching is applied by extending the etching time, up to the side face of the electrode 2 is etched. The frequency is adjusted by utilizing it and applying over-etching until the side face of the electrode 2 while checking the frequency.

Title: Semiconductor storage device
Inventor: WATANABE MASAHIRO
IPC: H01L21/822
Filed: 1983-11-11
Abstract: PURPOSE:To decrease the check time by adopting the constitution that internal data are outputted in parallel to plural input terminals at test. CONSTITUTION:An RAM passed the test is used as a storage device of the titled device and a test signal phiT at always high level is impressed to a test terminal 10 in this case. Then block selection signals phiB, phiB' commanding to which memory array block read/write is to be conducted are inputted together with address input signals A0-A13. Since the test terminal 10 is kept to a high level at all times in case of the normal operation, switch circuits 9A-9D are always in broken state. Furthermore, only a switch of a memory cell array block of a block selection circuit 7 selected by the block selection signals phiB, thetaB' is conductive and others are broken. Thus, in normal write/read cycle, only one memory cell of the selected memory cell array block is selected, and the write of an input data DIN and the read of an output data DOUT are attained via the block selection circuit 7.
