Title: Automatic focusing device
Inventor: AKAMATSU TAKESHI
IPC: G03B13/36
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To perform the precise focusing action of an object including high luminance by giving a function comparing, judging and selecting information inputted from two systems to a microcomputer. SOLUTION: The optical signal of the object made incident through a focus lens 1 is converted into an electric signal by a projection element 2. Besides, it is inputted to the microcomputer 4 and a highlight clip circuit 6 after the contrast component thereof is extracted by a signal processing circuit 3. The microcomputer 4 inputs the signals from the processing circuit 3 and the clip circuit 6 and controls a lens driving part 5 to drive the lens 1. In the case that the judgement action of the normal signal in a in-focus point direction and the judgement action of the highlight clip signal in the in-focus point direction are reversed, it is judged by the microcomputer 4 that the high luminance is included in the object and the inputted information is switched to the highlight chip signal from the normal signal.  Thus, since the in-focus direction and the in-focus point are decided, the precise focusing action is attained.

Title: Low pressure mercuric vapor electric-discharge lamp
Inventor: ONO TETSUO
IPC: H01J61/20
Filed: 1984-09-21
Abstract: PURPOSE:To alleviate staining of the outer tube of a bulb-type fluorescent lamp having the outer tube and inner tubes by specifying the amount of mercury charged in the lamp. CONSTITUTION:The amount of mercury charged in a bulb-type fluorescent lamp having an outer tube 1 and inner tubes 4 and 4' is adjusted to at most 5mg. Almost regardless of the shapes of the outer tube 1 and the inner tubes 4 and 4', the above requisite is common to those lamps where the coldest area is located in the outer tube. It is difficult to charge a small amount of mercury in the lamp. It can be achieved by placing an alloy getter or capsule containing a proper amount of mercury in the lamp and then producing mercury by high-frequency heating. It is also possible to control the amount of mercury charged in the lamp by constantly extruding a given minute amount of mercury from a mercury injector. In order to enable a minute amount of mercury to smoothly roll into the lamp, it is recommended to cover mercury with a powder of alumina or similar material.

Abstract: PURPOSE:To generate automatically vector data of a boundary line of a character picture by extracting the boundary line of the character picture and applying straight line approximation, circular-arc approximation and curve approximation to the said boundary line. CONSTITUTION:Noises are eliminated by a pre-processing section 2 from a character picture generated by performing raster scanning at an input section 1 to extract the boundary line, a continuous point string fetch section 3 fetches it as a continuous point string and a change point extraction section 4 generates the character picture whose change point is extracted from the point string. A straight line approximation section 6 applies straight line approximation to the character picture generated by the extraction section 4. A straight line approximation end decision section 7 applies convergence decision by the straight line approximation and when the section 7 decides the unnecessary repetition of processing, it is informed to a circular-arc approximation section 8. The approximation section 8 applies circular-arc approximation to a character picture except the picture subjected to straight line approximation. A circular-arc approximation end discrimination section 9 applies the decision similar to that of the decision section 7. A curved line approximation section 10 applies the curved line approximation to a character picture other than those approximated by the sections 6, 8. When the convergence decision of the curved line approximation end decision section 11 is YES, vector data is outputted.
