Title: Fuel passage structure in carburetor
Inventor: SUI MASARU
IPC: F02M7/11
Filed: 1983-06-20
Abstract: PURPOSE:To reduce the pressure pulsation of fuel as well as to prevent a suction air-fuel ratio in time of high temperature from going to overthickness, by setting up a tank inside a fuel passage connecting a fuel pump to a carburetor. CONSTITUTION:In the case where temperature in fuel flowing in a fuel passage 12 is high enough, the sectional area of a tank 15 is larger than that of the fuel passage 12 so that a flow rate inside the tank 15 is decreased to some extent. Therefore, the fuel vapor generated inside the fuel passage 12 comes stagnant inside the tank 15 and stays on top of the tank 15. As a result, a hydraulic level is fuel inside a float chamber 4 of a carburetor 13 drops, reducing a fuel quantity to be sucked out of a fuel nozzle 18, thus a suction air-fuel ratio becomes rarefied.

Title: Distortion correction circuit for quantitizing figure
Inventor: MORI NOBUHIKO
IPC: G06V10/10
Filed: 1980-08-12
Abstract: PURPOSE:To take out figure information after correcting distortion in each column or each row by storing the figure corresponding to one column or one row in the quantitizing figure information in a shift register while shifting figures sequentially from the end and specifying the number of shifting times in every column or row with a counter. CONSTITUTION:The quantitizing value of each point of an input figure with distortion which is sent from a scanning device 7 is stored sequentially in a shift register and the distortion correction values which have been previously set up corresponding to the initial point of each row are written in a counter 10 which controls the number of shifting times of a counter 8. Thereafter, the correction value is subtracted by one on each writing-in with shift clock 11 of the register 8, and when the contents of the counter 10 become ''0'', the counter 10 generates a signal BORROW indicating that the contents are ''0'', so that counting of the counter 10 and shift of the register 8 are inhibited. After the scanning device 7 has completed the scanning of one row, the contents of the register 8 are written in a memory 9 to store the input figure whose vertical distortion is corrected, onto the memory 9.

     CONSTITUTION: A light beam a, which is produced by modulating the recording signals from a terminal A by a drive circuit 1, is generated from a semiconductor laser 2 so that it may be introduced through a condensing lens 3 and a tracking mirror 4 into the center of an iris lens 5. The light beam thus introduced is irised  out the most at a point P into a fine spot, which is irradiated upon a disc 6 to  record the information. The light beam 6 from a He-Ne laser 10 is enlarged by a  projecting lens 11 so that it may be irradiated upon the disc 6 from the position out  of the center of the lens 5. The splitter 12 changes the optical path of the reflected  light c from the disc 6 to irradiate optical detectors 14 and 15. The output difference between the detectors 14 and 15 is fed to a lens drive device 13 so that the lens 5 may be moved up and down, even if the disc is vibrated by the rotations, so as to irradiate the fine spot P upon the disc.

Filed: 1994-05-25
Abstract: PURPOSE: To improve the yield of a semiconductor integrated circuit, so that a semiconductor substance cannot be contaminated by performing etching with the inclination part of the semiconductor substance in a vertical position. CONSTITUTION: A semiconductor integrated circuit is formed between a lower layer 10 and a photosensitive film pattern 14 provided on a semiconductor substrate, and the lower layer 10 is exposed by etching a semiconductor substrate 12 exposed by the photosensitive film pattern 14 as a specific angle using a first plasma gas.
