Title: Video mixing and amplifying device
Inventor: HASHI KENJI
IPC: H04N5/265
Filed: 1982-08-18
Abstract: PURPOSE:To eliminate the variation of an output level and at the same time to separate two fader levers each other to operate them independently by providing a fader signal control circuit which makes the relation between the gain of a gain control circuit K and 1-K. CONSTITUTION:The gains are varied by gain control circuits 33 and 34 for video signals supplied to video signal input terminals 31 and 32. Such video signals are transmitted to a video signal output terminal 39 via a mixing circuit 37. The signal sent from a fader volume 35 is supplied to both the circuit 33 and a fader signal control circuit 38. The circuit 38 receives the signals from fader volumes 35 and 36. When two fader levers are put close to each other, a signal is transmitted to the circuit 34 so as to maintain a relation between K and 1-K for gains of the circuits 33 and 34. In this case, the circuit 38 controls to obtain the fixed level of an output voltage although only the volume 36 has a minute shift if a grip error, etc. are detected. Thus two gains attain the relation between K and 1-K.

Title: Automatic thread cutting device in sewing machine
Inventor: AMAKUCHI EIJI
IPC: D05B65/02
Filed: 1988-06-09
Abstract: PURPOSE:To shorten a cut thread end length and to omit a work to arrange a thread end with a scissors after embroidery is completed by sliding two facing cutters mutually in an approaching and separating direction, to cause sliding quantity to be different, cutting the threads and executing the cutting just under a throat plate or near the throat plate. CONSTITUTION:Since a hook 7 forms a V-shape at an angle determined in advance, to a lower movable blade 8, the hook 7 is always in advance. The thread is hung by this hook and when the lower movable blade 8 swing to the angle, which is determined in advance, a pin 15 is abutted to the inner circumference surface of a hole 9H. Further, the pin 15 pushes an upper movable blade 9, which faces to this blade 8, through a hole circumference surface by the sliding of the lower movable blade 8. At such a time, the pin 15 moves in the same direction as the lower movable blade 8 with a shape 13 as a center. However, since the other upper movable edge 9 is pivotally attached to a shaft 16 in a position which is separated from the shaft 13, the upper movable blade 9 is swung in the opposite direction of the lower movable blade 8. Thus, the both facing upper and lower movable edges 8 and 9 are swung in a closing direction and the thread to be hung by the hook and to be fed is cut like being sandwiched mutually.

Filed: 1990-06-01
Abstract: PURPOSE:To apply run length encoding to quantized data in a spiral form by applying DCT operation to four-block picture data adjacent to each other, varying the order of multiplication of coefficients of the DCT operation and collecting the data subject to DCT operation to the center of the four blocks. CONSTITUTION:In the case of applying 2-dimension DCT operation to a picture data, one picture data of four blocks adjacent to each other is subject to DCT operation and the data subject to DCT operation are collected in the middle of the four blocks as shown in two-dashed chain lines. Thus, the order of multiplication of coefficients is changed and since the DCT operation in a picture data of a block 1 is implemented in the right direction and in the downward direction according to the arrow, the data subject to DCT operation are collected to the lower right of the block 1. Moreover, the data subject to DCT operation are collected similarly in the middle of the four blocks in the picture data of the other block 1. When the data subject to DCT operation is quantized succeedingly, the run length encoding is implemented in spiral from the center of the four blacks as shown in the broken line arrow in figure 2.

Title: Manufacture of polycrystalline infrared-light fiber
Inventor: HAYASHI YOSHIAKI
IPC: G02B6/02
Filed: 1984-07-11
Abstract: PURPOSE:To improve the transmission of infrared light by drawing material crystal into a fiber in the crystal axis direction in which the hardness is smallest, and attaining an increase in mechanical strength and reduction in deterioration due to repetitive curvature and also suppressing a decrease in transmissivity due to moisture absorption and exposure. CONSTITUTION:The material crystal is extruded into a fiber in the crystal axis direction in which the hardness is smallest. For example, the crystal made of a mixture of TlBr and TlI is extruded into the fiber at high temperatures in a direction 110 or its equivalent direction. Namely, the mechanical property and infrared-light transmissivity of the fiber obtained by the extrusion vary greatly in the extrusion direction of the material single crystal. Namely, the crystal is extruded in a less-hardness direction to improve the adhesion of a grain boundary, thereby obtaining the excellent fiber which is tolerant to curvature and less in decrease in transmissivity and increase in absorption loss due to humidity. Consequently, intense infrared light is transmitted efficiently through this infrared-light fiber.

Filed: 1988-06-13
Abstract: PURPOSE:To prevent the destruction of oriented films at the time of rubbing and to improve yield by subjecting substrates to an inspection of the pattern defects of the electrode patterns, then subjecting only the non-defective substrates to formation of the same potential patterns, rubbing treatment, cell assembly, etc. CONSTITUTION:After plural pieces of the electrodes 2 are simultaneously formed on a sheet of the glass substrate 1, the substrate is inspected for the pattern defects by passing large current to the electrode patterns 2 or by other methods. The same potential patterns 3 which short-circuit the terminals 2a of the respective electrodes 2 from each other are formed on the substrate judged to be non-defective. The oriented film 4 is then formed on the patterns 2 exclusive of the terminal parts 2a and the surface thereof is rubbed in a specific direction. The two substrates which are subjected to the rubbing treatment and are integrated by orthogonally disposing the respective electrode patterns so as to face each other are cut t produce multiple pieces of the empty cells and to disconnect the same potential patterns 3. Liquid crystals are sealed into the cells in the final. Since the terminal parts 2a are short-circuited by the same potential patterns 3 prior to the rubbing treatment, the destruction of the oriented films is prevented.

Abstract: PURPOSE:To reduce core loss, and to prevent the generation of scrap when a blank piece is cut by connecting the connecting section of an external leg and a yoke in stepped shape and stacking and connecting the connecting section of a central leg and the yoke in apparently x-shape form. CONSTITUTION:The iron core blank pieces forming the external leg 17 and the yokes 20, 22 and the iron core blank pieces shaping the external leg 18 and the yokes 21, 23 are constituted while being each displaced in stepped form at every one layer. The iron core blank pieces forming the central leg 19 and the iron core blank pieces shaping the iron cores 20-23 are molded in structure in which the iron core blank pieces with a parallelogram are stacked alternately in the connecting sections.

The generation of the scrap of an electric steel plate can be prevented when the iron core blank pieces of the legs and the yokes are cut by stacking, laminating and joining the connecting sections of the legs 19 and the yokes 20-23.
