Abstract: PROBLEM TO BE SOLVED: To provide an image processor for extracting image data by making a user instruct one point in image data and for automatically tracking the contour line of the image data by considering the line width of the contour line. SOLUTION: When the user instructs one point on a picture with a display/ digitizer 101, the presence/absence of a pixel having data in a prescribed direction from this point and having the prescribed line width over 8 pixels around the pixel having these data is retrieved. By tracking the pixel having the prescribed line width from this pixel, contour line tracking is performed. When the pixel having the prescribed line width over 8 pixels around pixel does not exist, a pixel satisfying the said conditions is retrieved oppositely to the said prescribed direction and by tracking a pixel having the prescribed line width from the retrieved pixel, contour line tracking is performed.

IPC: H05B3/00
Filed: 1986-12-29
Abstract: PURPOSE:To prevent any accident due to a malfunction in a relay switch from occurring by controlling a first relay switch, which performs an on-off changeover alone, for opening or closing, and also controlling a second relay switch for its changeover with output of a heater selector circuit. CONSTITUTION:One end of two heaters 3 and 4 is connected to a power source via a first relay switch in common use, while the other end of these two heaters 3 and 4 is connected to a transfer terminal of a single-pole, double tilt type second relay switch 11. And, this transfer terminal of the second relay switch 11 is connected to the power source, and these first and second relay switches 8 and 11 are made so as to be controlled for opening or closing by two relay drive circuits 14 and 15. Supposing that a contact piece of the first relay switch 8 to do troublesome on-off operations by temperature control has been deposited, these two heaters 3 and 4 are connected to the power source via the second single-pole double tilt type relay switch 11 to be controlled less in frequency by a heater selector circuit at the other end. With this constitution, not to mention that such an accident as these two heaters 3 and 4 are simultaneously energized is brought to nothing, such a possibility that the second relay switch 11 gets out of order due to deposition or the like becomes lessened.

Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To realize a waveguide structure and a current constricting structure together by constituting at least the layered part of a semiconductor laminate having a light guiding function of a compound semiconductor layer containing phosphorus. SOLUTION: A ZnO film 111 is deposited on a semiconductor substrate by the sputtering method. Then zinc is diffused from the film 111 by heating a wafer on which the semiconductor laminate is formed to a temperature between 500 deg.C and 600 deg.C in a nitrogen atmosphere. Of the zinc-diffused area, a compound semiconductor area 105 containing phosphorus as a main group V element can secure a high resistance value together with the refractive index change of the material, because the resistance value of the zinc-diffused area 112 of the second clad layer 105 composed of n-type (Al0.7Ga0.3)0.5In0.5P containing phosphorus as a main group V element increases. Namely, the zinc-diffused area 112 constitutes a waveguide and, at the same time, a current constricting layer. Therefore, no additional current constricting structure is required.

IPC: G11B5/86
Filed: 1993-12-14
Abstract: PURPOSE:To prevent video software having copy rights from being dubbed by making VTR video recording of a TV signal difficult. CONSTITUTION:A time per one field of a standard TV signal converted into a digital signal is deviated partly from 262.5H of the standard TV signal to generate a read timing so that the time by a consecutive frame is made different.

A timewise relation from a vertical synchronous signal till the video signal is kept identical to that for the standard TV signal. The normal operation of a servo circuit for a rotary drum and a capstan of a VTR is disturbed by revising a field length of the standard TV signal.
