Title: Position detecting phase difference detection device and position detection system and its method
Inventor: GOTO TADATOSHI
IPC: G01B7/00
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To realize both removing of a phase fluctuation error due to the cause other than a position to be detected such as temperature change and others, and high speed responsibility. SOLUTION: The output signal is inputted from a position sensor 10 such as a resolver, etc., which outputs two alternating output signals, whose amplitude are modulated according to different two function values (sign and cosine) corresponding to the position. The electrical phase of one of the inputted alternating output signals is shifted by a specified angle, and it is added to and subtracted from the other, and two electric alternating signals (sin(ωt±d+θ), sin(ωt±d-θ)), which are provided with the electrical phase angles (θ) corresponding to the position, and phase-shifted (14) in reverse direction, are electrically synthesized.  Contrary to the two signals, of which phase differences (θ) corresponding to the position are shifted in positive/negative reverse direction, phase fluctuation errors (±d) are in the same direction, so that each phase shift amount (±d+θ, ±d-θ) are measured and precisely calculated for offsetting or extracting the error (±d), and the precise phase difference (θ) are detected. The data of error (±d) is also the temperature detection data.

Title: Front frame of pinball machine
Inventor: ANDO TOSHIO
IPC: A63F7/02
Filed: 1990-11-05
Abstract: PURPOSE:To easily control a slump at a playing field by integrally molding a surface skin layer and a foamed layer through a molten state from a thermoplastic resin for a front frame and integrally molding a play panel fitting member. CONSTITUTION:A front frame 3 of a pinball machine 1 is integrally molded from a synthetic resin and composed of three layers such as a skin layer 3A, foamed layer 3B ad the skin layer 3A. On the back side, a play panel fitting member 320 is integrally molded so as to surround a window hole 301. Since a boundary part between the surface skin layer and the foamed layer on the front frame is set after passing through the welding state caused by heat, the surface skin layer and the foamed layer are integrated and hardly separated and the strength of the front frame can be prevented from being deviated by the separation. Further, since the play panel can exactly be fitted through the play panel fitting member to the front frame side in a state with small fitting error, the pinball machine capable of easily control the slump is obtained.

Title: Pulse width modulation circuit
Inventor: HO HIYON KIMU
IPC: H03K7/08
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To output a PWM signal with a simple circuit configuration by separating a data pulse signal into selection signals A, B, generating a delay signal D through the processing of the signal A and a clock signal C and allowing logic gate section to process the signals B-D. SOLUTION: A data register stores a pulse width data signal (a) consisting of a gate selection signal (c) generated by a most significant bit and a delay selection signal (b) generated by remaining low-order bits. A delay signal generating section 12 allows n-sets of unit delay circuits to delay sequentially a reference clock signal (e) depending on a value of the signal (b) to output delay signals d0-dn. Furthermore, the generating section 12 processes the signals d, b and selects any of the signals (d) and a logic gate section 13 receives the signals (d), (e) and applies NAND processing to them by using a signal (c) and outputs a PWM data signal. Thus, the pulse width is smoothly adjusted to generate a pulse with a high density and then the circuit is simplified by omitting a counter and a comparator.

Filed: 1990-11-05
Abstract: PURPOSE:To detect the absolute position of a mobile mechanism with a comparatively simple device constitution and in a small working range by providing a code train in the working direction of a mobile machine and attaching a code detecting sensor to a movable part of the mobile machine. CONSTITUTION:A code train 6 is provided in the working direction of a mobile machine, and a code detection sensor 5 is attached to a movable part 4 of the mobile machine. A drive part 1 is driven by a prescribed extent, and the count value of a counter is stored when the code detected by the sensor 5 varies. Then the absolute position of the mobile machine is decided based on the count value of the counter which is working by a prescribed extent. Thus no synchronization is required between the reading operation of the train 6 and the working of the part 1 owing to a fact that the value of the counter is stored when the code detected by the sensor 5 varies. In such a way, the absolute position of the mobile machine is obtained with a simple device constitution.

IPC: B23K20/02
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a method to remove burrs when a wire is cold-welded with pressure. SOLUTION: A die 6 to weld a wire with pressure is built in between a movable V block 9 and a fixed V block 10. The die comprises four die pieces, and the movable V block 9 is pressed against the fixed V block to weld the wire to be held by the die pieces. A pressure-welded part of the wire is compressed by the die pieces. An insertion plate 7 is held between two die pieces. When the die 6 is compressed, the die pieces holding no insertion plate 7 hold the wire while the rest of two die pieces do not hold the wire. Thus, the die pieces holding the wire are moved to the side of the die pieces holding no wire. The wire is also moved to the side of the die pieces in which the insertion plate is not held, and burrs are pressure welded and removed by the die pieces.
