Title: Burst one-wave gate circuit
Inventor: KAWANAKA RYUTA
IPC: H04N9/455
Filed: 1987-12-30
Abstract: PURPOSE:To eliminate an analog part, to apply large scale circuit integration and to make the size of the circuit small by replacing a monostable multivibrator having been used in a conventional burst one-wave gate circuit into a variable shift register and replacing a phase comparator into a phase difference counter and a preset value arithmetic circuit. CONSTITUTION:A shift register 4 whose delay stage number is variable is used, an phase difference between an output of the shift register 4 and a burst signal is counted by using a clock 2nfsc (n>=2) from a PLL oscillator 9 and the delay stage number is controlled based on the count output. Thus, a shift register output is obtained before several clocks of one specific wavelength of the burst signal to extract one wavelength of a burst signal thereby attaining the constitution of logic circuit. If any dropout takes place in a horizontal synchronizing signal, the data before the production of dropout is held to make the effect of dropout not susceptible.

Inventor: SHIBUYA SATOSHI
IPC: B24C9/00
Filed: 1989-12-27
Abstract: PURPOSE:To reduce the amount of shot particles being brought out of a blast chamber as well as to decrease the extent of environmental pollution by shot- blasting both upper and lower surfaces of a strip with the shot particles and then blowing off the shot particles remaining on top of this strip. CONSTITUTION:A tensile stress acts on the topside of a strip 2 and a compressive stress on the underside, respectively, causing their plastic deformation, and thereby very minute permanent deformation is given to both sides of the strip 2 run past a bending roll unit 7. With the effect of this permanent deformation, the strip 2 is formed into a C camber in the cross direction. Next, the strip 2 formed into the C camber is pinched of both edges by each pair of presser rolls 8, 8 set up in both inlet and outlet sides each of a blast chamber 1, and it is passed through the bending roll as holding the C camber in the cross direction, in the blast chamber 1, and first of all, surface scales on both upper and lower surface of the strip 2 are removed by shot particles being projected out of a shot projector 3. Afterward, residual shot particles are blown off by sprayed air out of an air head 5.

Filed: 1990-11-29
Abstract: PURPOSE: To reduce wavelength deviation caused by light source oscillation and to eliminate the need for calibration at lamp replacement by providing a plate containing a light dispersion surface which evenly distribute the light from a light source on an entrance slit. CONSTITUTION: An infrared ray from a light source 12 is, through a plate 21, transferred to a surface, where the infrared ray is dispersed so that an entrance slit 18 is evenly irradiated. Then the slit 18 emits the light having constant angle distribution toward a diffraction grating 20, and the grating 20 is oscillated at high speed by a drive motor 22. The grating 20 disperses infrared ray from the slit 18, and makes it to be reflection spectrum toward an outlet slit 26. A narrow wavelength band from the spectrum passes a slit 26 and a slit optical element before a sample 28 is irradiated with it. As the grating 20 oscillates, a center wavelength of the light passing the slit 26 is scanned in infrared ray spectrum. Then an optical detector 29 detects intensity of radiation caused when reflected on a sample, and then generates an output signal representing the intensity.

IPC: G09G5/42
Filed: 1990-11-30
Abstract: PURPOSE:To rapidly decide whether a segment is included in a window area or not by obtaining a vector connecting the start point of the segment to a corresponding end point in a clip area and deciding whether the center part of the segment is positioned in the clip area or not based upon the outer product of the obtained vector and the segment. CONSTITUTION:The y values (coordinate values rectangular to a scanning line) of both end points of a segment to be processed are compared and the 1st vector directed from the end point having the smaller y value to the end point having the larger y value is calculated. Then the 2nd vector directed from the end point having the smaller y value to a corner point to be the reference of the clip area is calculated and the outer product of the 1st and 2nd vectors is calculated. The positive/negative of the code of the outer product is decided and whether the segment to be processed is decided as a segment only a part of which, truely excluding both ends, is positioned in the clip area or not is decided. Consequently whether the whole range of the segment is positioned on the outside of the clip area can be decided and a time required for processing can be sharply shortened.

IPC: F01L1/08
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a cam follower, a valve lifter, and cam follower mechanism for an internal combustion engine which are easily manufactured, without increasing the cost in plastic working. SOLUTION: In this, cam follower 25, although the diameters of a center part 25b and end parts 25c, 25d are different from each other, heights h11 to h13 for each of maximum distance positions D11 to D13 are made to match with each other. In the case where the cam follower 25 are manufactured by mans of plastic working such as mold casting, the difference in depth between mold sides is not generated. Accordingly, a metallic material is filled fully into a mold by plastic fluid motion, even if press pressure is not increased by improving durability of press and the mold. Since the difference between thickness of products for posing the problem in spring back at the time of plastic working is not generated, accurate shape easily can be formed by the plastic working, where the plastic working has the advantage of working on a guide groove in a cam follower holder of the valve lifter.
