Title: Paper sheet cutting device
Inventor: OKADA YOICHI
IPC: B26D1/30
Filed: 1995-04-26
Abstract: PURPOSE: To provide a paper sheet cutting device which gives a warp in the same shape at all times and secures a stable sharpness in cutting by fixing a stationary cutter by a screw while its undersurface is supported by ribs protruding upward in positions in front of and behind a frame and giving a constant warp to the stationary cutter. CONSTITUTION: A paper sheet cutting device is equipped with a movable cutter 4 to cut a sheet of paper on the scissors system in the area to a stationary cutter 1, in which a base frame 3 is provided in the central part with a through hole to admit penetration of a screw 2, and ribs 3a to support the stationary cutter 1 are provided in front of and behind the through hole. The stationary cutter 1 is furnished with a threded hole 1b in the position mating with the through hole. The shape of the stationary cutter 1 is substantially plane in normal condition, but when placed on the base frame 3 and secured by the screw 2, a warp is generated because the front and rear extremities of the cutter 1 are supported by the ribs 3a while the central part is fastened by the screw 2. The shape of the warp is the same at all times because the position and height of the ribs 3a are constant.

Title: Automobile telephone set
Inventor: HIRATA EIJI
IPC: H04B7/26
Filed: 1987-04-28
Abstract: PURPOSE:To detect the disabled communication generated locally by providing a detection means receiving a signal from an in-service area detection means and a communication disabled means so as to detect the communication disable regardless of the service area. CONSTITUTION:A reception section 100 of an automobile telephone set receives a radio wave, outputs a reception signal and gives an electric field intensity signal and S/N to a spot area detection section 101. The detection section 101, based on the two signals, detects a spot area. As to the reception disable or difficulty due to mountains or buildings, the resulting phenomenon differs from the analog and digital communication telephone systems. In the case of the digital communication, the deterioration in the S/N is eminent more than the notch width of the electric field intensity, in the spot area. Thus, the electric field intensity and the S/N are treated as quantity and it is possible to detect that the entrance to the spot area is reached at a point of the signal where the S/N is deteriorated more than the weakened electric field intensity.

Title: Semiconductor laser
Inventor: KAKIMOTO SHIYOUICHI
IPC: H01S5/22
Filed: 1981-07-01
Abstract: PURPOSE:To equalize temperature distribution, and to extract high output by forming  a diffusion layer, the central section thereof has high carrier concentration, so that  currents are focussed at the central section more than an end surface. CONSTITUTION:The P<+> type diffusion layer having carrier concentration higher than a  layer 10 is formed into a P<+> type diffusion layer 21 in order to reduce additional  resistance up to the P-N junction 21 from an electrode 7. In this case, a layer 11 is started from a position where entering an inner section than one end surface 31, and  ended at a position where entering an inner section than the other end surface 32.  Consequently, there is no layer 11 in the vicinity of the end surfaces 31, 32. As a  result, the additional resistance of a current path up to the junction 21 from the electrode 7 also increases in a region where there is the layer 11 in the sections in the  vicinity of the end surfaces. Accordingly, currents in the vicinity of the end surfaces  31, 32 decrease more than the central section, and currents focus at the central section.  However, the absorption of beams and a temperature rise are scattered to the central  section and both ends because a temperature rise in the vicinity of the end surfaces  and the reduction of a band gap are generated by the center of recombination formed  to the surface, and high output can be extracted.

Title: Device and method for generating free curved surface
Inventor: SAITO MASARU
IPC: G06T17/20
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To attain a free curved surface generating device capable of generating a free curved surface corresponding to dot group data and easily correcting a part of the free curved surface. SOLUTION: A triangular net is formed in a dot group and a false normal regulated by the triangular net is found out in each dot. The triangular net is transformed into a tertiary Bezier curve and a tertiary Bezier curved surface is generated in an area surrounded by the tertiary Bezier curve to obtain a free curved surface. A point satisfying a prescribed condition is extracted from the dot group and a new curved surface is generated by the use of the feature point. Thus free curved surfaces can be separated into a curved surface generated based upon a feature point and the other curved surface. When both the curved surfaces are individually processed, a part of the free curved surface can easily be corrected to an optional shape.

Filed: 1983-06-13
Abstract: PURPOSE:To precisely detect the shift between a screw hole and a workpiece in an automatic screw tightening device provided with a detector for the relative positions of a screw tightening machine and the screw hole, by symmetrically arranging a light-emiting sensor and a light receiving sensor which are directed to the center axis of the secrew hole.

If a driver part 6, a screw 1 and a screw hole 2 are aligned with the same axis, the light is reflected by the inside of the hole, and therefore, does not reach the light receiving sensor 3-b. If the screw hole is shifted, the light reaches the light receiving sensor 3-b after being reflected by the workpiece 13, and therefore, a signal from the light receiving sensor 3-b is used to judge between the enabling and disabling of screw-tightening in the non- contact condition of the screw 1 with the workpiece 13.
