Title: Photo change-over device
Inventor: TERAI SEIJI
IPC: G02B26/08
Filed: 1978-12-28
Abstract: PURPOSE:To make the device simple, inexpensive and minuature without using any reflecting mirror by deviating the central axis of two planoconvex lenses by a desired size and bonding these mutually at their plane parts to integrate them in changing over transmission optical paths. CONSTITUTION:In the position opposing to the primary side optical transmission wire 101 are disposed the plural secondary side optical transmission wires 102, 103, 104, 105 on the concentrical circumference centering at the exit optical axis A, by way of the optical path change-over means 106 which combines two planoconvex lenses 107 and 108. The optical path changing-over is accomplished by moving the central axis b of the lens 108 in parallel to the central axis a of the first lens 107. A beam is made to parallel beams by the convex face 109 and the parallel beams are sent to the convex face 110, where the change-over means 106 is rotated about the axis a, by which the beams are entered to, e.g., the optical transmission wire 102. In this way, the selective changing-over of the transmission optical paths is made possible by the rotation of the change-over means 106 and the movement of the lens 108.

Title: Line head position deciding method for character
Inventor: NAKAZAWA TAKASHI
IPC: G06F17/24
Filed: 1994-06-24
Abstract: PURPOSE:To comparatively regularly arrange characters by smoothly moving line head positions along a border line by defining a prescribed parallel line faced to a partition line settled in the border line of a rectangular area as the line head position of characters in that line. CONSTITUTION:After a border line 4 and the character partition lines of respective lines are displayed on the display screen of an interactive input device, a minimum deviation amount unit (a) is decided. In the case shown in figure, the (a) is 1/3 of a character height 2. When plural parallel lines parallel to a line expressing the start points of lines and mutually provided with intervals (a) are drawn concerning the character partition where the border line 4 crosses the line expressing the start points of the lines of character partition lines, the first parallel line in the border line 4 is defined as the line head position of that line. Concerning a first line 11 and a second line 12, the position deviated from the line head position in the case of assuming the rectangular area just for (a) becomes the line head position and concerning 3rd-5th lines 13-15, the deviation amount is '0' since the line expressing the line start points of character partition lines does not cross the border line. Therefore, the line head positions of respective lines smoothly move along the border line like a polygonal line 5 shown in figure.

Title: Hologram laser unit
Inventor: NAGAOKA YUKI
IPC: G11B7/125
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a hologram laser unit which can be mounted collectively without causing any deterioration of the characteristics or performance. SOLUTION: A hologram element 3 is bonded through an adhesive 5 to a package 1 and a cut 8 is made in the package 1 as a part for communicating between the inside 1a and the outside of the package 1. Consequently, even if the component of the adhesive 5 is partially evaporated on the inside 1a of the package 1, it is discharged through the notch 8 to the outside and the inside of the package 1 is not filled with the eyaporated component. Since the gas pressure does not increase on the inside 1a of the package 1, the hologram element 3 is not shifted by the vapor pressure even if the bonding strength of the adhesive 5 is deteriorated.

Abstract: PURPOSE: To provide a moving image encoding device which has high compressibility of data in a simple constitution by using a difference processing means which acquires the difference between the frames of data that undergone the dither processing, the data selection means and an encoding control means which decides and controls the encoding system. CONSTITUTION: An encoding control means 60 initializes the encoding condition that is given from an input means 70 and compares this condition with the compressed code value to decide whether the simple moving image data to be inputted can be compressed. Then the means 60 decides the compression processing method when the moving image data can be compressed and sets an encoding condition flag (dither, difference and compression). Based on this flag, the encoding is carried out with execution or no-execution of the processing of a dither processing means 1O, an inter-frame difference processing means 30, the data selection means 20 and 40, and a compression processing means 50 respectively. In such a constitution, the optimum encoding system is selected and the data compressibility is improved. Thus the effective encoding is possible for the moving images.

Title: Gas detecting element and manufacture thereof
Inventor: YAMADA KEIICHI
IPC: G01N27/12
Filed: 1981-10-16
Abstract: PURPOSE:To improve reliability, by a method wherein a change in resistance, in which gas concentration inherent to a metallic oxide serves as a factor, is increased in dependency. CONSTITUTION:A gas detecting element 1 consists of an assembly 3 of particles 2 of a metallic oxide showing a change in resistance to gas, a terminal 4 embedded in the assembly 3, and a good-conductive melt 5 with which a space between the terminal 4 and the particles 2 is filled.

This prevents a resistance between the assembly 3 and the terminal 4 from being influence by the size of the gas, and as a result, a change in resistance, in which a concentration inherent to a metallic oxide serves as a factor, is increased in dependency, and a signal having a high reliability is obtained.
