Title: Manufacture of rectangular insulation cable
Inventor: YOKOYAMA HIROSHI
IPC: H01B13/00
Filed: 1991-07-26
Abstract: PURPOSE:To set a large ratio of width to thickness in a rectangular insulation cable large, prevent peeling of insulation paint, and manufacture the cable easily by forming a hollow tubular insulation cable by applying an insulation coating on a hollow conductor, and pressurizing it perpendicularly for moulding it. CONSTITUTION:Insulation paint for enamel coating for an insulation coating is applied on the outer circumference of a tubular hollow conductor 7, so a hollow tubular insulation cable 6 is extrusion-moulded by a circular die. The cable 6 is then pressurized perpendicularly for forming a flat insulation cable 9. In this case, for pressurizing it, it may be sent between rolling rollers, or it may be pressurized by a pressure means such as a plate. Crushing the cable 6 can be performed easily if the pressure of the rolling rollers is not large, and because a large pressure is not loaded on the coating 8, the coating 8 is not damaged, so cracks or the like are not produced in it. A cable 9 having a large ratio of width to thickness can thus be manufactured easily.

Title: Rom type multiplying device
Inventor: CHIBA KAZUHIRO
IPC: G06F7/52
Filed: 1985-08-26
Abstract: PURPOSE:To omit such a case where two different types of multipliers are used to obtain positive and negative multipliers respectively, by using a single multiplier properly by a multiplication mode switching signal between the multiplication of two positive numbers and the multiplication of two negative numbers respectively. CONSTITUTION:When both a multiplier X and a multiplier Y are positive, the logic of a switching signal 10 is equal to 0 and both the multiplicand X and multiplier Y emerge as they are at the outputs of exclusive OR gates 1 and 2. These X and Y are supplied to ROMs 3-6 in the form of multiplicand and multiplier for arithmetic. Then the product P of X and Y is delivered from an adder 9. When both the multiplicand X and multiplier Y are negative, the signal 10 is set at logic 1 and the most significant bits of both X and Y undergo the logical inversion through both gates 1 and 2 together with other bits kept as they are. Thus the multiplicand and the multiplier for arithmetic are produced and the product of X and Y is delivered from an adder 2.

Abstract: PURPOSE:To improve the position accuracy and to keep the sharpness of a scope by operating a center position respectively based on a change in a photodetector and using a coordinate given by the center position as an input position when plural photodetectors are shut by an object such as a finger. CONSTITUTION:An input circuit 11 applies processing extracting only an output with respect to a light of a frequency being an object from output signal of a photodetector 5 and the extracted signal is given to a control circuit 12. A threshold value is set to an output signal in this circuit 12 in order to exclude the effect of dust and discriminate the shut light intensionally and when the output of the photodetector is lower than the threshold value, it is discriminated that it is an intensional shut such as a finger. When the controller 12 detects that this output is low, a group of the photodetectors having an output level lower than the threshold level is extracted. Then the light shield range is obtained based on the change in the output of a group of the photodetectors in longitudinal and lateral directions extracted in this way to obtain the center coordinate of the range.

Filed: 1988-07-29
Abstract: PURPOSE:To reduce a noise and oscillation generated by the impulse of a video head and a video tape by providing small projections in parallel on the feeding plane of the tape along a tape guide part. CONSTITUTION:An upper cylinder 7 on which the video head 6 is fixed is fixed on a disk 5, and a rotary transformer 8 is fixed adhesively on the other end plane of the disk 5. Recording and reproduction are performed by protruding the video head 6 slightly over the tape sliding plane of the upper cylinder 7, and bringing it into contact with the magnetic tape.

Abstract: PURPOSE:To uniformize the consumption of a target and to stably form a sputtered film having a uniform compsn. and film thickness by rotating a disk disposed plural magnets on the rear surface of the target of the planar magnetron sputtering device to uniformize the density of the target. CONSTITUTION:Symbols 1a, 1b, 1c denote three pieces of the magnets which vary in sizes and which all form annular magnetic fields smaller than the target size. The respective magnets are formed respectively independently and are so arranged that the entire surface of the above-mentioned target 51 is covered with the plasmas confined in the above-mentioned annular closed magnetic fields (CMF) during the rotation of the disk. The plasmas confined in the annular closed magnetic fields (CMF), for example, the three annular plasmas rotate on the surface of the target 51 at nearly the uniform density when the rotary disk 65 is rotated around a revolving shaft 66 and, therefore, the target is sputtered at the sputtering speed nearly uniform over the entire surface. The consuming state of the target 51 is thus uniformized and not only the improvement in the life of the target but also the uniformization of the film thickness distribution and film compsn. distribution of the target film are attained.
