A condenser for a carrier recovery apparatus of a liquid imaging system is provided. The condenser for a carrier gas recovery apparatus of a liquid imaging system for recovering a carrier gas as a liquid carrier by collecting and condensing the carrier gas evaporated by a drying unit of the imaging system, includes a bubble generating member provided at a vapor discharging end of a gas duct for inducing the collected carrier gas into the liquid carrier contained in the condenser. The bubble gene...

A squeegee roller cleaning apparatus for a liquid electrophotographic printer includes a plate installed at a tray, parallel to the axial direction of a squeegee roller, under a photoreceptor web to be capable of pivoting. A surface-contact blade member is supported at the plate so as to selectively surface-contact the outer circumferential surface of the squeegee roller. An elastic spring is coupled between the tray and the plate. A device makes the plate pivot such that the surface-contact bla...

A multiple speed reproduction method and apparatus records a multiple speed reference signal to enable a head to accurately scan the position where an I frame is recorded during a multiple speed reproduction. The method and apparatus controls a duty ratio of a control signal which is recorded on a control track, and reproduces the multiple speed reference signal for use by a servo system during the multiple speed reproduction.

A vibration wave motor obtains a desired pressure using a piezoelectric device. The vibration wave motor includes a vibrator which is supported by a shaft and has electro-mechanical conversion elements for generating a travelling vibration wave progressing along the circumferential direction around the shaft when a first electrical signal is applied to the vibrator. A rotating unit which has a portion which is in press-contact with a surface of the vibrator, perpendicular to the shaft, rotates a...

The present invention relates to a projection monitor, and in particular to a projection monitor having a darkroom casing capable of preventing a penetration of a foreign material and any leakage of light and easily assembling reflection mirrors which guide the image projected by the engine to a screen. The projection monitor having a darkroom casing according to the present invention includes a front casing having a screen installed on a front surface of the same, a rear casing engaged to the b...

A liquid carrier withdrawal apparatus for a liquid electrophotographic imaging system for withdrawing a liquid carrier by separating the liquid carrier from a developer liquid embedded on a photoreceptor for a liquid electrophotographic imaging system. The liquid carrier withdrawal apparatus for a liquid electrophotographic imaging system using a mixed liquid of a toner and a liquid carrier as a developer liquid for developing a latent image formed on a photoreceptor, includes a core rotatably i...

A carrier recovery apparatus of a liquid electrophotographic printer includes a condenser for condensing a gas carrier recovered from a photoreceptor belt, a filtering tube having a cavity, whose first end is connected to the condenser, and whose second end has a plurality of throughholes leading to the cavity radially formed thereat, a filter bonded on the outer surface of the filtering tube and which filters the gas carrier contained in air passing through the throughholes, and an exhaust tube...

A power applying circuit for an internal logic circuit includes a plurality of basic power applying units coupled to the internal logic circuit in parallel, each of the basic power applying units including a logic gate unit outputting a pulse in response to two input signals having a time interval with respect to each other, and a transmission gate coupled to the logic gate unit and receiving the pulse.

An absolute angular position calculator for a rotating motor and a velocity control apparatus adopting the same, in which a separate pulse generator is not used. The motor is manufactured so that a modified frequency generator generates a modified frequency signal by removing one pulse from the predetermined number of pulses of a frequency signal, by changing a duty of one pulse of the frequency signal, or by changing a magnitude of the frequency signal. When the motor is in use, a modification ...
