Title: Board with photocatalyst film and its manufacturing method
Inventor: TOYOSHIMA TAKAYUKI
IPC: B01J21/06
Filed: 2000-04-06
Abstract: PROBLEM TO BE SOLVED: To solve a problem that a sustained hydrophilicity of a board is not sufficient even in the case that the board is coated with a photocatalyst film of titanium oxide and then coated with a hydrophilic film thereon so that the surface is made to have a hydrophilicity and dirt proof by photocatalytic effect. SOLUTION: The photocatalyst layer of titanium oxide is coated by sputtering on a glass plate, and fine particles of silicon dioxide are sprayed onto the photocatalytic layer as a masking reagent. After coating the photocatalytic layer on which the fine particles have been sprayed, with silicon dioxide, the sprayed fine particles are desorbed and removed. Thereby, a glass plate that has the photocatalytic layer of the titanium oxide and a number of micropores where the photocatalyst layer is exposed outside and is laminated and coated with the hydrophilic layer of the silicon dioxide can be obtained. This photocatalytic film is excellent in antifogging persistency.

Filed: 2000-04-12
Abstract: PROBLEM TO BE SOLVED: To provide an image pickup device which can improve its S/N by increasing the charge accumulation time of an image pickup element with a simple constitution and in accordance with the signal level of image data. SOLUTION: An image pickup element 11 performs photoelectric conversion of an optical image that is formed on an image pickup screen and accumulates the electric charge. A drive circuit 13 generates drive signals by means of the clock signals generated by a 1st oscillator 14 and drives the element 11. The oscillator 14 generates clock signals of frequency accordant with the input voltage. A processing circuit 15 performs the image processing to the image signals which are outputted from the element 11. The image data that undergo the image processing are converted into analog video signals by a D/A converter 20 via a multiplier 201 and a scan converter 17. A control part 16 varies the control voltage to the oscillator 14 to increase the value of image data when this value is lower than the standard signal level.  When the oscillator 14 lowers its oscillation frequency in response to the control voltage, the time span of drive signal generated by the circuit 13 is expanded and the charge accumulation time of the element 11 is increased.

Filed: 2000-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a game machine having a control board capable of preventing (restraining) a fraudulent practice such as replacing a program memory with a fraudulent program memory while enabling the replacement of the program memory. SOLUTION: A main control board C is composed of a plate-like first base board C1 and a film-like second base board C2 detachably connected to the first base board C1. An MPU 14 for storing a control program of a game is soldered to the second base board C2. Thus, the control program of the game can be changed by replacing the second base board C2 by being removed from the first base board C1. It is difficult to make the MPU 14 for mounting various functions on one chip in the form soldrable to the film-like base board C2 due to requiring an advanced technology and large-scale equipment. Thus, the fraudulent practice of replacing a fraudulent one-chip MPU with the normal MPU 14 by making the fraudulent one-chip MPU is made unperformable to prevent (restrain) the fraudulent practice.

Abstract: PROBLEM TO BE SOLVED: To solve the problems which are caused by an impulse due to an error of estimation by deciding the scaling compensation of a quantizer from a vectorial linear non-adaptive estimation algorithm when the transmission of a voice frequency area data form is encoded and decoded. SOLUTION: When the transmission of a voice frequency area data form is encoded and decoded, the scaling compensation of a quantizer is decided from a vectorial linear non-adaptive estimation algorithm. For instance, an encoder 1 inputs a signal Sn and its estimated value and leads the difference of them to a TCQ(trellis coding quantization) retrieval/Viterbi decision block 10 via a preamplifier 5. In regard to the information which are inputted to the block 10, the relative inputs generated from a block 12, i.e., the extension super code books and their difference are processed. Then these information are sent to an estimator 16 via a gain scaling device 15. All operations needed for a TQC algorithm are carried out by the block 10.

Title: Reciprocating compressor
Inventor: MORI YUJI
IPC: F16C9/00
Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of breakage due to gouging and wear due to partial contact without needing precise flattening in a direction, in which the axial load of a connecting rod is exerted, in a reciprocating compressor. SOLUTION: Since a notch part 7 is formed in a direction in which it crosses an axial load 80 of a connecting rod 71 during compression of gas applied on the connecting rod 71, an adverse influence on precision occurs not during compression of gas but during a low load. Thereby, precise machining is not necessary to the notch part 77 and even when worsening of precision occurs to machining of the notch part 77, precision of a small and large hole parts 72 and 76 is ensured. The occurrence of breakage due to gouging and wear due to partial contact can be reduced and since the notch part 77 forms an angle of 180 deg. around the large hole 76, dislocation hardly occurs and assembly is facilitated.
