Title: Resonance circuit
Inventor: FUSHIKI TATSUROU
IPC: H03H11/12
Filed: 1980-07-05
Abstract: PURPOSE:To simplify a resonance circuit and to save power and to make the distortion factor low, by constituting the resonance circuit which can selectively obtain a number of resonance frequencies with one amplifier. CONSTITUTION:When the K-th input terminal AK is alternatively selected, the J-th input capacitor BJ and the (J-1)th input resistor FJ-1 inserted between a connecting point EJ-1 other than a connecting point EK-1 and the J-th input terminal AJ  other than the K-th input terminal AK are niglected, and the synthesized resistance value of the 1st - the (K-1)th voltage dividing resistors D1-DK-1 inserted in series between the connecting point EK-1 and the input terminal of an amplifier 21 can be neglected because the input impedance of the amplifier 21 is close to infinite value. Thus, this resonance circuit becomes equivalent to the series connection of a capacitor in CK, resistor which is the sum of RK-RN+1 and HK-1 and inductance in value of [(sum of RK-RN)XRN+1XC0].

Title: Numerical controller
Inventor: YONEDA TAKAO
IPC: G05B19/414
Filed: 1980-07-04
Abstract: PURPOSE:To prevent an accumulation of errors due to the rounding to the nearest whole number in the arithmetic process of pulse number, by adding the cumulative extent of shift stored in a shift accumulating means with every read of the extent of shift and the present extent of shift and then distributing the pulse number based on the result of said addition. CONSTITUTION:A data writing device MDI, a memory M and a driving circuit DU that drives a servomotor SM are connected to a numerical controller NC consisting  of a microprocessor or the like. At the same time, the controller NC is used for the memory M to store the desired numerical control program NCP. Furthermore the pulse number is cumulatively stored in the memory M every time when the pulses are distributed in accordance with the programed extent of shift. Then the cumulative extent of shift stored with every read of the extent of shift is added to the read-out extent of shift, and the value obtained by multiplying the result of addition  by a constant plus the pulse number equal to the deviation to the stored pulse are applied to the circuit DU. Thus an accumulation of errors due to the rounding to the nearest whole number is prevented to ensure a highly precision positioning.
