Title: Projection color display device
Inventor: NAGAE YOSHIHARU
IPC: G02F1/015
Filed: 1991-03-19
Abstract: PURPOSE:To present the projection color display device reducing the frequency of light source exchange and practically unnecessitating the exchange of a light source. CONSTITUTION:For the light source, three single color CRT 2, 5 and 8 varying the maximum intensity wavelength area are used, liquid crystal elements 1, 4 and 7 are irradiated with these beams, and they are synthesized to a color image by a dychroic prism 10 and displayed with colors on a screen 12 while being enlarged and projected by a projection lens 11. The service life of the CRT is more than 10000 hours and it is from five times to ten times as long as that of a metal halide lamp. Even when being close to the end of the service life, the CRT is not extinguished like a lamp and therefore, the usable time of the projection color display device can be considerably prolonged.

Title: Robot with machining tool and its method for machining
Inventor: TERADA AKIHIRO
IPC: B23K26/08
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a robot with a machining tool and its method for machining, which are capable of precisely and simply carrying out cutting of a pipe end face, saddle-shaped cutting, drilling on a pipe side face and also machining of a three-dimensional work surface like a workpiece having various planes. SOLUTION: A machining tool 11 is attached to the last shaft 1 of the movable arm of a robot. This machining tool 11 is equipped with a first additional movable shaft that extends/contracts vertically and a second additional movable shaft 11c that extends/contracts horizontally. By the rotation of the last shaft 1, the cutting tool (laser machining nozzle) at the tip end of the machining tool is rotated, so that a pipe-shaped workpiece W is cut. By the rotation of the first and the second additional movable shafts 11c concurrently with that of the last shaft 1, saddle-shaped cutting and drilling are performed. Since the movable arm of the robot is only for the rotation of the last shaft 1, machining precision is improved. In addition, cutting including saddle-shaped cutting and drilling can be easily performed on a pipe-shaped workpiece W.

Abstract: PROBLEM TO BE SOLVED: To lessen a change in a processing load in one cycle of a processing cylinder and thereby to enable quiet and smooth execution of a processing and also continuous use of an existing conventional die, in a sheet processing wherein processings of die-cutting a corrugated fiberboard sheet in the shape of a developed box and also scoring, for instance, are executed by a die-cutting edge and scoring edge which are fitting to the processing cylinder rotating. SOLUTION: A processing cylinder is made movable selectively to a right- angle position where it is positioned at a right angle to a sheet feeding direction and to a tilt position where it is tilted at a prescribed angle, from the right angle, to the sheet feeding direction. At the right-angle position, an ordinary straight die, for instance, is fitted to a die-cutting cylinder 1 and the same sheet processing as usual is executed, while at the tilt position, a processing edge so tilted as to offset the tilt of the die-cutting cylinder 1 is fitted to the cylinder and the processing is executed. Thereby the processing, such as quiet and sharp die cutting in a so-called point cut state, can be executed.

Title: Manufacture of magnet roll
Inventor: HIRAI MASATOSHI
IPC: H01F41/02
Filed: 1990-03-26
Abstract: PURPOSE:To reduce irregularity of magnetic force both in the longitudinal direction and in the angular direction, prevent the protrusion of turnings and adhesive agent, and remarkably improve productivity, by inserting a shaft while pressing and stretching a cylindrical type magnet with compressed gas, and fixing the shaft by using contraction force of the cylindrical type magnet, via a high friction layer instead of adhesive agent. CONSTITUTION:The inner diameter of a cylindrical type magnet 2 is formed to be a little smaller than the outer diameter of a shaft 1. A high friction layer 3 is formed on the inner surface of the magnet 2 or on the surface of the shaft 1. After the magnet 2 is cut into a specified length, compressed gas is introduced from one end, i.e., the side opposite to the insertion side of the shaft, and the inner diameter is pressed and stretched. In this state, the shaft 1 is inserted. Inert gas such as air or nitrogen is used as the compressed gas, and in particular, air is preferable. The cylindrical type magnet 2 into which the shaft 1 is inserted is magnetized, and turned into a magnet roll.

IPC: G01N27/26
Filed: 1993-03-13
Abstract: PURPOSE:To measure with high accuracy by dividing the potential difference by the measuring number for every calibration and correcting the measured value with the use of the coefficient. CONSTITUTION:Supposing that 60 samples are mounted on a sample cup 6 of a turntable 7, the analyzer is so initialized that one point calibration is conducted for each of, e.g. 30 samples.

Title: Light distributing device
Inventor: KOBAYASHI ISAO
IPC: G02B6/28
Filed: 1978-06-28
Abstract: PURPOSE: To realize light distribution function and enable distribution ratios to be readily set by  combining the focused flux of the light beam in the direction perpendicular to the center by one- dimensional focusing type light transmission body and the flux of the light beam in the direction  rectangular to this focusing direction by the curved face.   
     CONSTITUTION: The end part of an incident optical fiber 2 is installed to the incident end face 11  of the first one-dimensional focusing type optical transmission body 1 having the refractive index  distribution decreasing in proportion nearly to the square of distance from the center toward the  periphery only in the Y direction and the first to fourth semi-circular cylinders 3 thru 6 are installed to the exit end face 12 thereof in such a manner that their axes become parallel to the Y axis.  The second one dimensional focusing type optical transmission body 2 having the refractive index  distribution nearly identical to that of the first one dimensional focusing type optical transmission  body 1 only in the Y direction is installed in proximity to the semi-circular cylinders 3 thru 6, and  the end parts of the first to fourth exit optical fibers 22 thru 25 are installed to the exit end face 14  thereof. Since in this way the light beam diameters hardly changes in the Y direction and are  separately focused by the semi-circular cylinders 3 thru 6 in the X direction, insertion losses may  be reduced and since the optical element for distribution is disposed in the spread place of the light  beams, the distribution ratios may be readily set.
