Title: Photocoupled multiplex circuit
Inventor: ISHII KAZUHIKO
IPC: H04B10/03
Filed: 1982-08-02
Abstract: PURPOSE:To eliminate a power supply from an output circuit, and to improve reliability of the titled circuit, by applying the photoelectric conversion to the output of a digital signal output circuit corresponding to each system via an optical control means which is decided by the majority logic, after synthesizing the output by a digital signal output circuit common to each system via an optical transmitting means. CONSTITUTION:The outputs of digital signal output circuits 3a, 3b and 3c are delivered in the form of optical signals by driving emission LED22-24 to emit light at the final stage. These optical signals are sent to a digital signal output circuit 5 common to each system via optical fibers 25-27 and then synthesized to undergo the photoelectric conversion by a phototransistor 29 via an optical attenuator 28 for control of light quantity. In this case, a solid state relay 30 is turned on for the attenuator 28 if two of the LED22-24 are active to emit light. Thus a control subject 7 is controlled via the relay 30.

Title: Grid device for color cathode-ray tube
Inventor: KUME HISAO
IPC: H01J29/07
Filed: 1981-08-26
Abstract: PURPOSE:To reduce the weight of a grid device, by two-dimensionally bending two arms for holding a grid under tension and by placing the joints of frame sides outside Bessel points. CONSTITUTION:Since each of two arms 20c, 20d is bent as U on a plane, their rigidity is increased so that they can be made of a metal pipe of small thickness or diameter. This results in reducing the size and weight of a grid device by the addition of the decreasing of its total length. The joint of the arms 20c, 20d to frame sides 20a, 20b are placed outside the Bessel points so that the ratio I1/I2 of the second moment of area of the frame sides to that of the arms is set at 1.5 to 2.0. For that reason, a grid 21 can be held with a prescribed distribution of tension between the frame sides 20a, 20b.

Title: Sewing machine
Inventor: SATO MASATO
IPC: D05B69/12
Filed: 1989-05-26
Abstract: PURPOSE:To provide a sewing machine which forms a stable and neat stitch by a method wherein an upper shaft motor is run at a predetermined speed, and running of a lower shaft motor is controlled so as to coincide with the rotation phase of the shaft motor. CONSTITUTION:When a reference signal of a sine wave by means of which a sewing speed is generated is inputted from a reference signal generating circuit 19 to a phase amplifier 20, a phase difference amplifier 20 detects a phase deviation between a reference signal and a sine wave signal from a first angle detector 23. A proportional voltage is amplified by a power amplifier 21 to input it to an upper shaft motor 22, which is run at a specified speed. When a phase difference signal proportioning the rotation angle of the upper shaft motor 22 is inputted from the first angle detector 23 to a phase difference amplifier 24, the phase of the upper shaft motor 22 is compared with the phase of a lower shaft motor 28 detected by a second angle detector 29. When an output from a phase difference is inputted through the phase amplifier 24 to a power amplifier 27, an output is amplified and inputted to the lower shaft motor 28, which is run in a state to be synchronized with the rotation angle of the upper shaft motor 22. As a result, a neat and stable stitch can be formed.

Title: Continuous casting method of steel plate
Inventor: FUKASE HISAHIKO
IPC: B22D11/06
Filed: 1983-07-26
Abstract: PURPOSE:To suppress effectively the growth of a solidified shell generated at the terminal of a pouring inlet in the stage of casting continuously a molten steel into the space between cooled casting molds which face each other at a suitable space and move circumferentially in the same direction by bringing the molten steel into contact with a specific part. CONSTITUTION:For example, cooling rolls 1, 1 are rotated in an arrow direction and a molten steel 2 is supplied to frame bodies 3 of both rolls. A solidified layer 5 formed by said rolls is cast continuously to a steel plate 6. A solidified shell 12 is formed to grow on the inside surface of the bottom end part 3a of the frame body 3 and the shell 12 solidifies to connect the boundary 4 between the roll 1 and the body 3 in some case. If such sheel is left intact, shearing force is acted in the solidified and connected part by the revolution of the rolls 1 and in a worse case the body 3 is broken by the resultant flaw and crack therefrom. The flow of the molten steel is thereupon divided by the peak part of a guide body 20 in the state of supplying the molten metal from above into the body 3 so as to flow downward along the slope of said body to collide vigorously against the boundary 4. The shell 12 under growth is then quickly melted by a large amt. of continuous heating received to the high-velocity flow of the molten steel and the formation thereof is suppressed.
