Title: One-bit error cancel circuit
Inventor: KUMAZAWA NAOKI
IPC: H03M1/10
Filed: 1990-02-26
Abstract: PURPOSE:To cancel one-bit error at a bit change point caused from the deviation in the characteristic of each A/D converter by comparing outputs of a couple of A/D converters operated sequentially, and controlling the outputs of a couple of the A/D converters in response to the output. CONSTITUTION:A data outputted from an A/D converter 1 is latched by a latch circuit 3 by a signal phi1 and inverted by an inverter 5 and the inverted output is fed to a full adder 6. On the other hand, a data outputted from an A/D converter 2 is latched at a latch circuit 7 by using a signal phi2, the signal is fed to the full adder 6, in which the data from the A/D converter 1 and the data from the A/D converter 2 are subtracted and the result is fed to a digital comparator. The output of the digital comparator is one-bit, then the data of the A/D converter 1 is outputted successively from a selector 4, while the data of the A/D converter 2 is outputted from the selector 4 when the data is not 1-bit.

Title: Optical fiber, method for manufacturing and connecting optical fiber, detector for its fracture, and optical communication device
Inventor: IKEGAMI KIMIKO
IPC: C03C25/42
Filed: 1983-03-16
Abstract: PURPOSE:To connect optical fibers with extremely small loss by providing a thin metallic film around the outer circumference of a core where light propagates or the outer circumference of a clad. CONSTITUTION:The long-sized core 1 which is made of quartz glass fiber has a 50mum core diameter is covered coaxially with a thin metallic film layer 5 which is made of nickel alloy and has 30mum thickness. The wall surface of the core 1 is finished specularly as the thin metallic film layer 5, so a total reflecting surface is formed regardless of the angle of light incidence. Therefore, incident light is reflected totally by the wall surface of the core 1 to travel straight toward then output terminal, so no light leaks out of the optical fiber.

Title: Color correcting device
Inventor: MITSUTAKE HIDEAKI
IPC: H04N1/48
Filed: 1987-02-27
Abstract: PURPOSE:To miniaturize a circuit scale and to reduce cost by constituting a color correction circuit by means of multistage table converters and alloting the effective bit numbers of plural input signal in the converters to assign in accordance with the degree of contribution with respect to output signals. CONSTITUTION:The table converters 11, 12 and 13 in a first stage consists of ROMs or ROMs in which inputs are below 8 bits and outputs are 8 bits. The inputs are set to be uncorrected R, G and B signals, and the outputs consist of the X, Y and Z signals of CIE 1931 standard colorimetric system of 8 bits. Consequently, the input bits of R, G and B respectively become high-order 6, 8 and 1 bits in the case of the Y signal, for example. The converter 14 inputs the X and Y signals having the effective bit number 8, and outputs the aX signal of 8 bits. The converter 15 inputs the Y signal having the effective bit number 8 and outputs the LX signal of 8 bits. A converter 16 inputs the Y and Z signals having the effective bit number 8 and outputs the bX signal of 8 bits. Consequently, the total of the table sizes of the converters 11-16 becomes smaller than that when all conversion are collectively executed.

Abstract: PURPOSE:To extremely easily regulate abrasion of a shim and to securely restrain generation of noise by screwing an adjusting screw into a pump housing and by providing a micro gap between the tip end of the adjusting screw and the axis end of a rotation axis. CONSTITUTION:Into a pump housing 2, an adjusting screw 23 is screwed so that its tip end is opposed to the axis end of a rotation axis 21 in the pump housing 2. By screwing the adjusting screw 23 by a predetermined amount, a micro gap S of about 100mum is formed between a tip end surface 23A of the adjusting screw 23 and a cone-shaped axis end 21A of the rotation axis 21. When a shim 18 is abraded by the same amount as the micro gap S, the cone-shaped axis end 21A is brought into point-contact with the tip end surface 23A, whereby regulates further abrasion of the shim 18. Thus, abrasion of the shim can be extremely easily regulated from the outside of the pump housing, generation of noise can be securely restrained, and life of a fuel pump can be drastically improved.

Title: Plasma cutting method and its device
Inventor: NAKANO ETSUO
IPC: B23K10/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce cutting time in cutting plural members from one sheet of material to be cut. SOLUTION: A route for a cutting torch A is set by arranging plural members on a material B to be cut. In a route from one member to the next, energization is stopped between the electrode of the cutting torch A and the material B, while power is supplied between the electrode 1 and the material B, so that the main arc is shifted into a pilot arc. With the cutting torch A reaching a start position for cutting a new member, the pilot arc is shifted into the main arc, carrying out the cutting of the member. There is no need of forming a pilot arc through the pre-flow for each member to be cut, which enables cutting time to be reduced.

Title: Image forming device
Inventor: OTANI MASAYUKI
IPC: G03G15/00
Filed: 1990-02-28
Abstract: PURPOSE:To reduce waste of time and to prolong service life of the device by carrying out initialization only when a correction means is moved at a time other than during an image forming action. CONSTITUTION:Out of output ports of a micro computer 20 as a control means, 4 bits are connected to a jogger motor 29. A photo coupler (movement detection device) is connected for movement detection of this motor 29, and its output is connected to an input port of the micro computer 20. The power source of the motor 29 is turned off by a relay when a front cover is opened, etc. In this state, when a jogger fence (correction means) 60a and 60b are moved, the input port of the micro computer 20 is made 'L' level, and this can be judged by the difference from 'H' at a stopped state. Then, only when movement of the correction means is detected regardless of the standby time, the initialization of the correction means can be carried out by the control means. Thus, the waste of time can be reduced and the service life of the device can be prolonged.

IPC: G01S7/52
Filed: 1992-02-01
Abstract: PURPOSE:To enable the realtime high-accuracy simulation of an actual complex state by generating a false signal simulating the output signal of each vibration receiving element, and inputting this false signal into an active sonar phasing apparatus. CONSTITUTION:The input signals of plural piezoelectric elements disposed at a wave transceiver 1 for transmitting-receiving sound waves underwater are inputted into a phasing apparatus 2 to perform directivity providing processing for obtaining the incoming direction of the acoustic signals. A signal processor 3 performs signal processing to sound echoes obtained by azymuth, and a display controller 4 prepares video data on the basis of the setting of an operator and displays it (5). Hereupon, an active sonar false signal generating device 6 generates a false signal in the same signal form as the wave receiver 1 receiving actually underwater. A switch 11 switches the actual signal and the false signal selectively. Since the false signal, simulating the input signal from the wave receiver 1 as it is, is thus inputted into the phasing apparatus 2 to simulate active sonar action, the displayed image has high realism.
