    摘要: A pressure compensated electromagnetic proportional directional flow control valve of the present invention integrally includes: an electromagnetic proportional directional flow control valve configured to be driven by a solenoid; and a pressure compensated valve configured to carry out pressure compensation of a flow rate controlled by the electromagnetic proportional directional flow control valve. A pressure compensation spool moves so as to balance forces of a spring, a first pressure chamber, and a second pressure chamber. With this, the pressure compensation for maintaining a constant pressure difference between an upstream side and a downstream side of a first variable aperture can be carried out, and a surplus liquid of a liquid flowing from a liquid-pressure supply port to a derivation port can flow out from a branch port to outside.

    摘要: Provided is a configuration in which: a spool driven by an electromagnetic proportional solenoid is urged by a spool-returning spring configured to exert urging force in an opposite direction to a driving direction of the electromagnetic proportional solenoid; a mechanical stopper is disposed at the stroke end of the spool; current dither causes a control current to micro-vibrate, the control current driving the electromagnetic proportional solenoid; and the mechanical stopper includes a stopper-urging spring configured to allow the spool to vibrate owing to the current dither even when the spool is in contact with the mechanical stopper. A proportional solenoid control valve with this configuration is capable of reducing hysteresis at the stroke end of the spool by means of the current dither, and controlling the spool in a stable manner over the entire control range including the stroke end of the spool.

    摘要: An image forming apparatus acquires an amount of deflection of the transporting sheet from a reference position thereof and calculates a required shift amount of the sheet. It determines whether or not the sheet is shifted frontward. If so, the image forming apparatus acquires a second specified shift value which is determined based on an urging force and the required shift amount using a second correction equation. Alternatively, if the sheet is shifted backward, the image forming apparatus acquires a first specified shift value which is determined based on the urging force and the required shift amount using a first correction equation. The image forming apparatus performs a registration roller shift correction based on the acquired first or second specified shift value.

    摘要: A step-down switching regulator is disclosed that includes a first switching element, a smoothing circuit part including an inductor and a second switching element for synchronous rectification, a switching controller circuit part, and a reverse current detector circuit part that detects a reverse current flowing from the inductor to the second switching element and interrupts the reverse current by causing the switching controller circuit part to turn off the second switching element upon detection of the reverse current. Detecting a change in a set voltage, the reverse current detector circuit part stops, for a predetermined period of time, the operation of causing the switching controller circuit part to turn off the second switching element due to detection of the reverse current, and after the predetermined period of time is over, causes the switching controller circuit part to turn off the second switching element upon detection of the reverse current.
