Title: Metal saw belt guiding device for tubular material cutter
Inventor: HAYASHI HIDEKI
IPC: B23D55/02
Filed: 1981-10-03
Abstract: PURPOSE:To enable cutting of a tubular material having large diameter, by supporting a sub-guide roll on the inlet and exit portions of a travel path then putting an endless metal saw belt and allowing it to stretch and travel on the back of a notch along a corrugated path. CONSTITUTION:An arcuate movable frame 5 is provided with a stretching notch 6 from the lower edge while a guide roll 7 and an inverted roll 8 are supported on both side frames 5, where the depth of the notch 6 is formed slightly larger than the diameter of the pair of rolls 7, 8 to fit in a large diameter tubular  material (a) while a mountain shaped projection 5' is provided with a travel  groove 9. Attitude holding members 10, 10 are fixed at both sides of the opening of the notch 6 where sub-guide pair rolls 11, 12 are supported on an inlet 9a  and an outlet section 9b of the travel groove while a top pair guide rolls 13, 14  are arranged between them. Consequently an endless metal saw 16 will travel in  the travel groove 9 in the back of the notch 6 in zigzag by means of sub-guide  pair rolls 11, 12. Consequently a tubular member having large diameter can be  cut by slightly increasing the weight of the arcuate movable frame.

Title: Switched capacitor line equalizer
Inventor: INAMI DAIJIRO
IPC: H04B3/14
Filed: 1988-06-28
Abstract: PURPOSE:To attain stable signal transmission by preparing an independent equalizing amplifier circuit to plural kinds of lines having a different loss characteristic, selecting the output of the equalizing amplifier circuit by an inter-code interference of equalizer output waveform and extracting the result as the output. CONSTITUTION:An equalizing amplifier circuit 1 sets an impulse sent via 0.5mmphi insulated paper insulation cable and an equalizing amplifier circuit 2 sets an impulse sent via 0.65mmphi insulated paper insulation cable so as to minimize the inter-code interference of the impulse response. When the transmission characteristic of the transmission line is equal to that of the 0.5mmphi insulated paper insulation cable or the like or close thereto and the inter-code interference of the replay of the sent pulse is within the permissible range, the output signal of the equalizing amplifier circuit 1 is extracted as the line equalizer output. On the other hand, when the transmission characteristic of a cable different from the 0.5mmphi insulated paper insulation cable such as 0.6mmphi insulated paper insulation cable is used, the inter-code interference is caused over a wide range toward the opposite polarity to that of the master pulse. Then when the inter-code interference detection circuit 4 is used and the inter-code interference reaches the permissible value or over, a switch 3 is changed over to extract the output of the equalizing amplifier circuit 2 as the line equalizer output.

Title: Denitrification of waste water
Inventor: HATANAKA KOUICHI
IPC: C02F3/08
Filed: 1979-12-07
Abstract: PURPOSE: To maintain at a proper level an amount of bacteria adhering onto carriers for a stable operational effect, by injecting nitrogen gas through the bottom of a packed tower of a denitrification apparatus so as to prevent the bacteria from excessively adhering onto the carriers.  
     CONSTITUTION: Nitrogen gas is injected at a proper linear speed through the bottom of a packed tower of a fluidized bed type denitrification apparatus, while waste water containing nitric and nitrous nitrogen is charged into the packed tower. The nitrogen gas injection fluidizes carriers with adhering denitrificating bacteria and also maintains at a proper level an amount of the bacteria adhereing onto carriers for a long period. Said proper linear speed is changed in accordance with the kind of the carriers, a packing ratio and the volume of the nitrogen, but is preferably in the range of about 2W20m/hr. Besides, in this invention process, an adhesion balance of the bacteria, as a result of the bacteria splitting from and growing fat on the carriers, is easily controlled by the linear speed of nitrogen gas.

Inventor: UKITA SHINJI
IPC: H04N9/79
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a digital camera which has good characteristics over all the sensitivity, moire and coloration of a highlighted part. SOLUTION: A complementary color filter 14 consisting of color elements of Mg, Ye, and Cy is mounted on the photodetection surface of a CCD imager 16. A pixel signal of a complementary color generated by photoelectric conversion is read out by a timing generator 20 and written to a RAM 26 through an A/D converter 18. A memory controller 28 interpolates the pixel signal stored in the RAM 26 and thus obtains two complementary colors having pixel absence. The interpolated pixel signal is further processing through the RGB conversion of an arithmetic circuit 32. The output of the arithmetic circuit 32 is processed by a signal processing circuit 34 and recorded on a recording medium 36. Filter elements of Mg, Ye and Cy are equal in sensitivity and higher than filter elements of R, G and B.  Consequently, characteristics for all the sensitivity, moire, and coloration of a highlighted part are superior to those of a conventional color filter.

Abstract: PURPOSE:To contrive to simplify the structure and operation of an automatic clamping device by a structure wherein a cam device, which follows a vertically moving arm in the direction normal to a hatch cover, is provided. CONSTITUTION:When a hatch cover 2 is shifted to the close position, a wheel 3 is supported by the rail part 20 of a vertically moving arm 16 and at the same time a hook 22 engages with a groove 21.
