Title: Ion laser tube
IPC: H01S3/03
Filed: 1992-03-19
Abstract: PURPOSE:To prevent the generation of a leak, which is generated by the deterioration of the frit glass of the junction parts of an AlN component with KB glass components due to discharge at the time of operation of a laser tube, by a method wherein the junction surface of the hollow pipe made of aluminium nitride is covered with a high- melting homogeneous glass and both ends of the hollow pipe are respectively bonded to the annular components made of a borosilicate glass via a low-melting glass. CONSTITUTION:A plurality of pieces of thin tube composite components 7 are hermetically sealed on the same axis using a zinc-borate high-melting glass 8 until an ion laser tube is formed in a thin tube length, by which a desired laser output is obtained, and thereafter, a hollow pipe 11, which is made of AlN, for building an anode 9 and a cathode 10 therein is connected to the components 7. Then, KB glass components 13 are respectively sealed hermetically on both ends of the pipe 11 using the glass 8 and a lead silicate low-melting glass 12 and a thin discharge pipe line is completed. Thereby, it becomes possible to lessen bubbles, which are generated on the interface between the AlN component and a low-melting point glass sealed part, and the deterioration of the low-melting glass at the time of operation of the laser tube and a leak in the junction parts of the AlN component with the KB glass components can be prevented from being generated.

Title: Manufacture of semiconductor
Inventor: YAMAMOTO YOUSUKE
IPC: B28D5/00
Filed: 1989-03-14
Abstract: PURPOSE:To eliminate steps at cleavage parts at the end surface of a semiconductor device and to obtain a flat surface by forming grooves for starting cleavage along the length of several hundred Xm from the end of wafer by selective etching. CONSTITUTION:When mechanical shock is applied to each groove 2 for starting cleavage, the cleavage occurs. Thus, elements are isolated by a 110 surface 5. Since the groove is not formed along the 110 surface 5, occurrence of steps at the cleavage parts which are formed by the deviation between the 110 surface 5 and the grooves can be suppressed. When the groove 2 for starting the cleavage is formed at the end of a wafer by selective etching in this way, the position of the cleavage is made accurate, and the 110 surface without the step in cleavage can be obtained.

Filed: 1995-03-23
Abstract: PURPOSE: To improve hydrogen concentration distribution and current density distribution by providing a plurality of sections which are different in gas permeability of an electrode base material for one of a pair of electrodes from each other. CONSTITUTION: A fuel electrode side electrode base material 6A is divided into four sections parallelly in each of the inflow direction of reaction air and that of fuel gas, and these sections are named a A section, a B section, a C section, and a D section in order of higher hydrogen concentration in the fuel gas, while reversely, hydrogen gas permeability in each of the sections is increased from the A section to the D section. That is, in the A section, gas permeability of a molding die, from which a molding material with the minimum pitch filling factor and the minimum size in carbon short fiber is previously released, is minimized, while in the D section, that is maximized, and in each of the B section and the C section, intermediate gas permeability is provided.  These plural kinds molding materials are integrally pressed and burnt, so that the base material 6A consisting of four sections, which are gradually different in hydrogen gas permeability, is produced. In this way, equal current density line is linearized in the flowing direction of the fuel gas, so that a difference of current density is hardly observed in this direction.

Title: Automatic focus detector
Inventor: ISHIDA TOKUJI
IPC: G02B7/34
Filed: 1987-03-18
Abstract: PURPOSE:To obtain a sufficient color temperature detection output regardless of a low luminance to correct the focus detection error by operating color temperature detecting photodetectors as the integral type. CONSTITUTION:Color temperature detecting photodetectors 13 and 14 are operated as the integral type, and capacitors and switching transistors are provided between color temperature detecting photo diodes 13 and 14 and buffers 29 and 30, between a monitor photo diode MPD and a buffer 28, and in preceding stages of buffers 31 and 31'. Outputs of color temperature detecting photodetectors 13 and 14 are stored in a storage means like a capacitor for prescribed time. The output voltage based on all of the electric charge stored (integrated) for the prescribed time is outputted as a color temperature detection signal. Consequently, even if an object has a low luminance and the quantity of photoelectric charge per time generated from color temperature detecting photodetectors 13 and 14 is small, the color temperature detection signal is outputted as a relatively large value as the result of integration for the prescribed time. Thus, color temperature correction is sufficiently performed even for a lower luminance.

Title: Antidazzle film and method for quantitative evaluation of antidazzle property
Inventor: FURUI GEN
IPC: H01J29/88
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To quantify the effect of an antidazzle property and to achieve the matching property with a visual sensitive test by casting light from a diffusive light source and specifying the reflected image brightness defined as the inclination of the luminance distribution of the regular reflection image to a specific value or below. SOLUTION: The surface of a sample 3 is irradiated with the light from the light source lamp 1 and the reflected image thereof is photographed by a CCD camera 2. The angles of the light source lamp 1 and the CCD camera 2 with respect to the normal of the sample 3 are made equal. The evaluation of the reflected image brightness at the various angles is made possible by varying these angles. A mask holder is attached to the light source lamp 1 to control the size of the light source. When the images are mirrored in a clear film not subjected to the antidazzle treatment, the inclination of the luminance distribution is nearly 90 deg.. If there is the antidazzle property, the mirroring-in images are blurred and the inclination of the luminance distribution is diminished. The reflected image brightness is, thereupon, quantified by the inclination of the luminance distribution.  The reflected image brightness of the antidazzle film is confined to <=70.

Therefore, the operator instructs a sentence position in the document files 21, 22 whose comparison is to be restarted in the next time to the man-machine interface part 2. In such a way, the document check is executed efficiently.

Abstract: PURPOSE: To let winding of film be done extremely accurately by providing a member for guiding the leading end small-width part of the film downward and making use of the difference in friction force after the leading end of the film contacts the winding member.  
     CONSTITUTION: A film is unrolled by every fixed length by a sprocket and its leading end small-width part A is wound to the winding member 9 composed of high friction material by way of the rubber roller 29 of an acception pressure means 11 and the roller 24 of a superposing pressure means 10. Here, a guide part 25 is provided to the means 10 and a large-diameter part 13a is provided to the lower part of the member 9. As a result of this, the small-width part A is so force advanced downward as to direct to the straight line track. Since the friction force of the member 9 is larger than that of the roller 29, the advancing speed of the inner film becomes higher than the speed of the succeeding film 4 and the small-width part A turning around the member 9 makes gradually closer contact with the outside peripheral surface. Thereby, the winding of the film may be performed extremely accurately.
