Title: Controlling method for pulse width of inverter
Inventor: MAEKAWA KATSU
IPC: H02M7/527
Filed: 1981-07-22
Abstract: PURPOSE:To alter the output voltage of an inverter completely proportionally to a frequency by inverting the logic level of a control output signal at the time point of function value N-F(theta+DELTAtheta) and again inverting it at the time point of 2F(theta+DELTAtheta) from the previous point, thereby generating a control pulse. CONSTITUTION:When a function value F(theta+DELTAtheta) is outputted from an ROM5, a presettable timer 6 counts clock pulses E up to the prescribed value N, and the output signal of the timer 6 is inverted after the time proportional to N-F (theta+DELTAtheta) is elapsed from the time point when a modulation start signal B is outputted. On the other hand, a timer 7 counts from 0 upto N, and since the clock pulse H is switched from E to I from the previous inverting time, the pulse interval becomes twice value, a timer output signal K is again inverted after the time proportional to 2F(theta+DELTAtheta) is elapsed, thereby generating a pulse width modulation signal L. In this manner, an ideal V/F control can be performed.

Title: Table apparatus
Inventor: SEKIYA TOMOJI
IPC: B23Q1/00
Filed: 1990-05-02
Abstract: PURPOSE:To prevent flexture of a guide shaft to effect a high accuracy positioning by providing a main table, which is slidable in a horizontal plane on a base in one direction, with weights acting in a direction of lifting the main table upwards and balancing the weights in a direction in which their gravitational forces act. CONSTITUTION:A main table 18 is driven by a drive section and is horizontally moved in a direction of X via a static pressure air bearing. A sub-table 20 is interlocked with the main table 18 and is horizontally moved similarly in a direction of X via the static pressure air bearing 25. Since the main table 18 is substantially orthogonally lifted upwards by means of weights 31 each having its mass set to 1/2 of the mass of a movable portion of the main table 18, the mass of the main table 18 is cancelled by the masses of the weights 31. Accordingly, the weight of the movable portion of the main table is not applied to a guide shaft 15 for guiding the main table 18. Since wires 30 are guided while table-side pulleys 26 are being rotated, a state of balance between the weight of the main table 18 and the mass of the weight 31 is established irrespective of any position of the main table 18 in the stroke of the same.

Filed: 1989-05-10
Abstract: PURPOSE: To simplify configuration by integrating a logic signal generation circuit and a sequence means at one element in the form of programmable logic element and using that element as a function for the characteristics of a charge transfer device using the programming of the element. CONSTITUTION: The output of a 1st counter CH corresponds to the terminal of a string and drives a 2nd counter CV. Two binary constitutions H and V are decoded by a decoder D, and control in the positioning and move of flip- flops B1-BN is enabled. The outputs of flip-flops B1-BN form control signals #cl-ϕN for driving the charge transfer device. These control signals ϕ1-ϕN are composed of clock signals for vertical and horizontal transfer and a clock signal for setting an output stage to '0', and according to any special case, the other logic signal can be designed, as needed. Thus, a fixed sensor/defect memory unit is dispensed with.
