Title: Backlash correction control system for servo motor
Inventor: IWASHITA HEISUKE
IPC: B23Q15/22
Filed: 1989-09-26
Abstract: PURPOSE:To reduce the burden of the control of backlash acceleration and to prevent quadrant projection and inward overcutting by raising the speed loop gain by a set prescribed extent in the period when the extent of backlash acceleration is added to a speed command to control the speed. CONSTITUTION:As for a transfer function 2, the value of a parameter alpha is set to '0' at the time of not correcting the backlash, and the value of the parameter alpha is set to a set value at the time of correction to raise the gain of the speed loop. When the sign of a position command Pc is changed, a speed command Vc is multiplied by (1+alpha) in accordance with the set parameter alpha, and a backlash acceleration extent BA is added to the multiplication result, and therefore, the integration value of an integrator is quickly inverted to output a torque command value Tc which overcomes the frictional resistance to drive a servo motor in the inverse direction. Thus, quadrant projection and overcutting are reduced to reduce the burden of backlash acceleration even if the extent of backlash acceleration is not exactly set at every machine.

Title: Diagnostic method for logic circuit
Inventor: MORIWAKI IKU
IPC: G01R31/317
Filed: 1990-09-18
Abstract: PURPOSE:To attain the effective merger of sub-circuits by changing a circuit with all FFs and all output pins defined as the virtual output of a composite circuit, applying the clocks for each of clock phases of all output points FF of the changed circuit, and performing a test while repeating the recovery of value of the input point FFs which are destroyed by the clocks. CONSTITUTION:An original circuit is reconstructed into a composite circuit (sub-circuit) with a flip-flop (FF) group having a scan-in operation for generation of the check series regarded as a virtual input terminal and an FF group having a scan-out operation regarded as a virtual output terminal respectively. Under such conditions, the FF output point cones defining only the clock phases different from the clock phase of an output point FF as the input point FFs are merged with each other. Therefore no unknown data is generated to the input point FFs caused by the clocks when the data are fetched to the output point FFs with application of the clocks. Furthermore the scan-in value to be given to the input point FF is kept correct even in a clock application state and no malfunction is produced. Thus it is possible to effectively merge the sub- circuits without giving any change to the existing logic.

Title: Synchronous adder
Inventor: HIRAMATSU KATSUHIKO
IPC: H04L7/02
Filed: 1993-09-10
Abstract: PURPOSE:To reduce a circuit scale by collectively squaring plural subcarrier signals. CONSTITUTION:In-phase components 11 and orthogonal components 12 of a reception signal transmitted with four subcarriers are inputted to A/D converters 21 and 22 and are digitized at several-fold sampling speed of the symbol rate. Outputs of converters 21 and 22 have waveforms shaped by combinational waveform shaping filters 35 and 36 and are squared by squaring circuits 37 and 38 and are added by an adder 39. The output has not only an envelope component but also 2-fold, 4-fold, and 6-fold high frequency components because of squaring in circuits 37 and 38, and only the envelope signal is inputted to an adding circuit 82 by elimination in a low-pass filter 50. Envelope data is obtained in this manner. Since a frequency converter is not required and only two waveform shaping filters and one low-pass filter are used independently of the number of subcarriers to execute the synchronous addition, the circuit scale is reduced.

Filed: 1990-09-20
Abstract: PURPOSE:To prevent noise by acting the stray capacitance of a varister of a surge absorber like a bypass capacitor for noise elimination, forming an LC filter with the capacitor together with a common mode choke and shielding the LC filter. CONSTITUTION:The stray capacitance of a varister in the combination between a common mode choke blocking the high frequency current of a signal line connecting to a telephone circuit and the varister of a surge absorber 2 acts like a bypass capacitor for noise elimination and the capacitor and the choke 3 form an LC filter to prevent the propagation of noise through the signal line over a wide band, thereby preventing an EMI noise from a generating source of spurious radio wave radiation. Moreover, since the choke 3 itself is a coil using a magnetic substance as a core, the choke acts like an antenna catching an electromagnetic wave and might send noise to a communication line, then the propagation of noise is prevented by covering the choke 3 and the varister of the absorber 2 or the like with a shield case 4 to prevent the action like that.
