Title: Bar code system with high information density
Inventor: NOMURA MASARU
IPC: G06K7/12
Filed: 1985-03-22
Abstract: PURPOSE:To obtain a large quantity of information by printing bar codes in many colors and scanning these symbols by the sensors that react only with each specific color. CONSTITUTION:Two types of bar codes (a) of red and (b) of blue are put on each other and printed in double colors as shown in (c). Then a blue color filter is first used to read the bar code symbols printed on a print surface in red. While a red filter is used to read the bar code symbols printed in blue. Thus it is possible to read the blue information only.

IPC: H01S3/038
Filed: 1985-03-22
Abstract: PURPOSE:To increase the lifetime of a cathode by forming at least part of the inner periphery of an enclosure and at least part of the outer periphery of a cathode in conical shape, and pressing and holding the cathode on the inner periphery of the enclosure by a spring member, thereby eliminating the play of the cathode.

Title: Cryopump
Inventor: MATSUDA NORIMOTO
IPC: F04B37/08
Filed: 1984-03-28
Abstract: PURPOSE:To vary exhaust speed without reducing the max. exhaust speed of the gas adsorbed into the second cryopanel by installing a temperature adjusting means so that the temperature of the panel can be adjusted and adjusting the temperature of the panel. CONSTITUTION:The voltage of a power source 72 not shown in the figure is automatically controlled according to the temperature of the second cryopanel 5 including the second cold station 58 and adsorbent 64. By this apparatus, exhaust speed can be varied by only setting the temperature of the second cryopanel 59 including the second cold station 58 or adsorbent 64. Therefore, exhaust speed can be varied without reducing the max. exhaust of the gas adsorbed into the second cryopanel 59 including adsorbent 64. Since the temperature of the second cryopanel 59 including the adsorbent 64 can be raised without exceedingly raising the temperature of the second cold station 58, regeneration-work time can be reduced further.

Filed: 1981-04-16
Abstract: PURPOSE:To reduce the cracks in glass films and to improve the yield rate of mesa type devices by providing the glass films in mesa grooves between pellets in an Si wafer, providing coarse surfaces, and dividing the wafer into the pellets. CONSTITUTION:The mesa grooves 12 and 13 are provided between the pellets of the Si wafer as specified, and glass protecting films 14 and 15 are formed. Then the device is immersed in fluoric acid for a specified time, glass surfaces are etched, and coarse surfaces m1 and m2 are formed. The coarse surfaces m1 and m2 are stronger than a mirror surface mechanically and thermally. Cracks are hard to be generated in the surfaces even though external forces are applied at the time of scribing and breaking and the cracks are not expanded. Furthermore, since the coarse surfaces of the glass m1 and m2 are not intimate with solder, solder short circuits can be eliminated if the sufficient distance l is maintained between a bump 21'' of the solder 21 which is protruded at the time of mounting a pellet 1 and the pellet, and stable mounting can be performed. In this constitution, the yield rate and the reliability of the devices can be improved.

Title: Automatic focus control system
Inventor: YAMAZAKI SHIGEKI
IPC: G11B7/085
Filed: 1988-03-14
Abstract: PURPOSE:To ensure an automatic focus servo pull-in action by changing automatically the set value of a slice level in accordance with the light quantity detected by a light quantity detecting means which detects the light quantity of the luminous flux received from an optical recording medium. CONSTITUTION:When a recording medium 1 having a comparatively small reflection factor is used, the positive peak amplitude value is set comparatively small for the automatic focus detecting signal which shows the S-shaped characteristics used for judging the start of a pull-in action. Under such conditions, the light quantity detected by a light quantity detecting means 9 is small and therefore the slice level is automatically set at a comparatively low point by a slice level setting means. While the positive peak amplitude value of said automatic focus detecting signal is comparatively large in case a medium 1 having a comparatively large reflection factor is used. In this case, the slice level rises up automatically with increase of the light quantity detected by the means 9. As a result, an optimum slice level is automatically set in accordance with the characteristics of the medium and the equipment to be used. Then a stable pull-in action is ensured.

Title: Device for detecting collision sound
Inventor: YAMADA KIMIO
IPC: G01H17/00
Filed: 1981-04-20
Abstract: PURPOSE:To prevent erroneous detection due to the variation in the detected signal waveform accompanied by the variation in the output of a reactor and in a flow rate at a reactor core, by providing a detecting circuit and an integrating circuit in place of an RMS circuit in a conventional device. CONSTITUTION:A detector signal 1 follows the rise up of the signal and inputted to the numerator input terminal of a divider 4 through the detecting circuit 2 wherein the signal is attenuated in accordance with a constant time constant. At the same time, the detector signal 1 follows the rise up and inputted to the denominator terminal of the divider 4 through a detecting circuit 7 wherein the signal is attenuated at a constant time constant and an integrating circuit 8. Since the integration time constant of the integrating circuit 8 is set at the sufficiently larger value than the time constant of the detecting circuit, the output is not varied even though the waveform is varied if the variation in the generating period of the peak value of the detector signal 1 is small. Therefore, the output of the divider 4 becomes constant, the ratio between the peak value of the detector signal 1 and the preset value of the comparator 5 is kept constant, and possibility of erroneous warning is eliminated.
