IPC: H01Q1/28
Filed: 1993-04-26
Abstract: PURPOSE:To reduce mirror surface error and improve the performance of an antenna by selecting a displacement shape of three sides of a regular triangle mesh element to be a proper parabola. CONSTITUTION:A reflecting face 9 of an ideal parabolic face is a reflecting plane, in which an apex is 0, a center axis is taken for Z axis in the orthogonal coordinate system X, Y, Z and a focal distance is F. A regular triangle film face formed by moving a border coioncident film face in parallel in which each side of a triangle is in existence on an ideal reflector face (APS by design) by the quantity of equation I is used for an optimum border coincident face.

Title: Method and device for producing animation
Inventor: TAMURA SHIGERU
IPC: G03B15/00
Filed: 1979-09-21
Abstract: PURPOSE: To make it possible to produce an animation accurately with efficiency while checking the motion of the animation, by shooting drawn pictures, one by one, by a television camera, by storing them in a video memory device and then by reproducing drawn pictures at a random time rate.  
     CONSTITUTION: An image on animation form 2 of a drawn picture placed on screen glass 1 is shot by television camera 5 and then stored in video processing unit 6. After information on several forms is stored, CRT7 projects the image on an animation form of white paper on screen 1 via projection lens 8, etc. Consequently, while the projected image is referred to, the next picture slightly changing in motion can be drawn. Thus, pictures preceding by one sheet are reproduced to drawn the next pictures in sequence and they are stored and reproduced as an animation for several seconds. The stored pictures for several seconds are further dubbed on VTR, so that an animation which consists of line pictures only but is 30min one can be reproduced without film procesing.

Title: Biaxial co-stretching of plastic film
Inventor: YANAGA SUSUMU
IPC: B29C55/16
Filed: 1986-05-28
Abstract: PURPOSE:To reduce the breakage of a film by a method wherein a clip, whose length in the advancing direction of a plastic film in a grip is different between an upper part and a lower part, is employed and the film is stretched while arranging the grip, whose clip is longer, on the lower surface of the plastic film. CONSTITUTION:A clip should have a length in the advancing direction of a film in a grip, which is different between an upper part and a lower part. In another word, the length of the upper part 3 and the length of the lower part 4 should be different. Further, the longer clip is arranged below the plastic film to expand it. The length of the clip is preferable to be 10-100mm and more preferable to be 20-80mm. The difference of the length is preferable to be O.5-10mm and more preferable to be 1-4mm. When the length and the difference of lengths are smaller than these values, the breakage of the film due to the concentration of stretching stress is readily generated and, on the other hand, when the same are larger than these ranges, the film is stretched between the grips of the clip and whereby not only the breakage of the film is generated readily but also the width of one set of clip becomes wide uselessly and the necking of the end portions of the film upon stretching becomes large.

IPC: H04N1/40
Filed: 1989-05-16
Abstract: PURPOSE:To prevent the increase in the quantity of code when a picture is coded by a facsimile equipment or the like by decreasing the setting range of a threshold level in a dither matrix more than the maximum variable range depending on the size of the dither matrix. CONSTITUTION:A 4X4 picture element dither matrix is assumed for a picture data conversion ROM 1. Bits b0-b3 of a picture data IDi are inputted to address inputs ADR0-ADR3, low-order 2 bits b0-b1 in the information bit representing a horizontal coordinate value are inputted to ADR4-ADR5 and low-order 2 bits in the information bits representing a vertical coordinate value are inputted to ADR6-ADR7 respectively. The threshold level Th of the ROM 1 is decreased less than the maximum variable range depending on the size of the dither matrix. Then a picture element is a black element when the density value of the picture element whose threshold level is 14 is 15 at the time of binarization with the condition of density value > threshold level and the element to be discriminated as a black level is not mis-discriminated to be a white level. Thus, the picture quality after the binarization is improved and the increase in the quantity of code is prevented even in the transmission of coding.

Abstract: PURPOSE:To perform correctly and surely graphite spheroidization of a cast iron by charging a graphite spheroidizing agent into a box delineated in the bottom of a ladle, covering the same with a refractory covering jig, and removing the covering jig upon completion of receiving the molten metal. CONSTITUTION:A graphite spheroidizing agent A is packed in a box 2 delineated with refractories 3 in the bottom of a ladle 1 and a refractory covering jig 4 is charged into the ladle 1 by means of a crane, etc. and is so installed as to cover the top surface of the agent A by a covering plate 42. A molten metal is then poured into the ladle 1 and when the receiving of the molten metal is completed, the jig 4 is pulled up and removed. The molten metal and the agent A contact with each other through small holes 45 of the plate 42 during the receiving of the molten metal as a result of the above-mentioned operation but the reaction occurring in such reaction is very slight and when the jig 4 is removed upon completion of the receiving of the molten metal, the agent A diffuses from the inside of the box 2 and contacts thoroughly with the molten metal. The spheroidization reaction is thus smoothly and surely effected.

Abstract: PURPOSE:To prevent the cracking of glass due to the temperature difference by performing the thermal processing while coating the outer face of a glass bulb with an insulation cover. CONSTITUTION:A panel glass 1 and a funnel glass 3 are fixed to a frit encapsulation zig 11. While an insulation cover 11a is provided above said zig 11 through a supporter 11b, and arranged to enclose the panel glass 1, frit glass 2 and the funnel glass 3.

Title: Decision feedback type equalizer
Inventor: OKANOUE KAZUHIRO
IPC: H04B3/06
Filed: 1988-05-18
Abstract: PURPOSE:To obtain a satisfactory reception characteristic even when the center tap of a decision feedback type equalizer is set at the arbitrary position of an impulse response on a communication path by including a reception signal before a k-th signal in a pre-transversal filter at a time when the k-th transmission symbol of a decision apparatus is decided. CONSTITUTION:The reception signal sampled at one symbol interval at an input terminal 10 is filtered at the pre-transversal filter, and is inputted to a differential circuit 140. The differential circuit 140 takes the difference of the output of the pre-transversal filter and that of a post-transversal filter, and outputs an obtained signal to the decision apparatus 100, and the decision apparatus 100 performs decision based on the the positive or negative condition of the differential circuit 140, and outputs a decision result to an output terminal 11 and a delay element 105, and delays an input signal by one symbol time. Since a k-th reception signal r(k) is included in a pre-filter at the time when a symbol a(k+1) transmitted at a (k+1)th order is decided by the decision apparatus 100, it is possible to comprise the pre-transversal filter capable of obtaining a true least mean square error.
