Title: Cleaning of steel plate surface by laser irradiation
Inventor: INOUCHI TOORU
IPC: C23G3/00
Filed: 1979-03-08
Abstract: PURPOSE: To remove lubricating oil rapidly and exactly in case where the output of laser is limited by the irradiation of laser at a fixed angle to the slope of the steel plate surface in a multi-reflecting manner using reflecting mirrors onto rolling lubricating oil adhered to the surface of the steel plate.  
     CONSTITUTION: While reflecting the laser R is a multi-reflecting manner by the reflecting mirror 9, the laser R inclined at 70° or more of angle to the slope N of the steel plate 3 surface is irradiated onto the steel plate 3 to which the rolling lubricating oil, etc., is adhered, where the effective passing distance of the laser R inside the lubricating oil 8 is expanded by the irradiation of the laser inclined at the angle and therefore the removal of the lubricating oil is performed more effectively, combined with the multireflecting irradiation of the laser. Thus, the scanning of the laser R can be eliminated. The multi-reflecting irradiation may be performed by providing a pair of reflecting mirrors to both ends of the steel plate 3 so as to make mutual reflection possible, or providing the mirrors at regular intervals in parallel with both sides of the surface of the steel plate 3, may be preferably as well.

Title: Adaptive interference canceler
Inventor: SUZUKI HIROSHI
IPC: H04B1/7107
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To provide an adaptive interference canceler which can improve its transmission characteristics and also is excellent in stability. SOLUTION: A desired signal is produced by a desired signal detection means DSC-DET and supplied to a complex conjugate generation means CC where a desired complex conjugate signal is produced. The multipliers 301 to 30n perform the adverse modulation of output signals X1(i) to Xn(i) by means of the desired complex conjugate signal and convert the included desired signal components into the low band frequency. Then these signal components are eliminated by high pass filters HPF1 to HPFn . Thus the output signals X1'(i) to Xn'(i) of the multipliers 311 to 31n contain only the interference signal components. Based on these generated interference signal components, the interference signal components are canceled.

Filed: 1981-02-27
Abstract: PURPOSE:To prevent an erroneous operation, by detecting breakage of a tape at every n rotations of a flyer, and judging that the tape has been broken when the pulse count number of a tape passing signal has reached specified value. CONSTITUTION:The tape detector 15 includes a light emitter 13 and a light receiver 14 that are oppositely positioned so that the tapes 6 pass therebetween, and the detector 15 is positioned in front of a point where the tapes 6 led from tape pads 5 adjacent to a tape winder are wound around an elongate member.

Abstract: PURPOSE:To make a picture and a sound seeable and hearable integrally by recording a visual conversion signal and an audio conversion signal in a magnetic tape sequentially in the longitudinal direction, and outputting the said signals separately by means of a change over switch. CONSTITUTION:As a cassette tape 1 runs, a control signal Q is first detected by a reproducing magnetic head 3.

Abstract: PURPOSE:To ensure an optimum visible range suitable for the driver, by optimumly adjusting the optical axis of an optical means for projecting a drive information image onto a front glass with respect to the eye point of the driver. CONSTITUTION:A control circuit 10 controls the rotation of a motor 8 in accordance with a signal from a control switch 9. Further, if the eye point of the driver is at a position 7' higher than the point 7, the visible range of a display image which is reflected at the point A on a front windshield glass 1 causes the display image 5 to lack its top since the image by a lens 3 is limited. Accordingly, the driver manipulates the switch 9 to change the position of a mirror 2 so that the image is reflected at the point B on the windshield glass 1, and therefore, the image of the lens 3 is displaced from 3'-A to 3'-B, thereby the display image 5 is set in the range which is limited by the above-mentioned image 3'-B so that the display image 5 may be observed within the visible range.
