A liquid crystal displayincludes: a light source; a liquid crystal display panel; a wire-grid polarization platelocated on at least one of a light-incident side and a light-emission side of the liquid crystal display panel, and including a base plateand a plurality of wiresarranged in stripes on the base plate; a projection lens; a cooling partwhich supplies wind to the liquid crystal display paneland the polarization plateto cool them; and a covering wallwhich covers end faces of the plurality of wiresand ends of a plurality of groovesformed between the plurality of wires, at a windward side of the polarization platein a flow direction of the wind supplied from the cooling part

Liquid crystal display device

An electric power steering apparatus comprises a charge-discharge circuit capable of configuring a circuit for charging an auxiliary power supply and a circuit for discharging a battery and the auxiliary power supply as well as configuring a discharge-preference circuit which enables only the discharge of the auxiliary power supply while avoiding the charge thereof. In the apparatus, a control circuit performs a power latch operation of carrying on control till the end of a predetermined period of time following an operation of turning off an ignition key, and also causes the charge-discharge circuit to configure the discharge-preference circuit thereby enabling steering assist accompanied by the discharge of the auxiliary power supply.

Electric power steering apparatus and control method therefor

A torque detector () is provided with first and second units (). The first unit () includes a first synthetic resin () formed by molding a pair of magnetic flux collector rings (A,B). The second unit () includes a second synthetic resin () fixed to a magnetic shield plate (B) containing a metal; an insertion protruding part () arranged on the synthetic resin (); and magnetic sensors (A,B) held by the insertion protruding part (). The first synthetic resin () includes a receiving plate () whereupon a base (e) for receiving the magnetic shield plate (B) is formed. In a status where the receiving plate () exists between the magnetic shield plate (B) and an object () to be attached, both the magnetic shield plate (B) and the receiving plate () are fastened to the object () by a pair of fixing screws ().

Torque detector

A reading apparatus of the invention has a high resolution reading part, a low resolution reading part, holding means for holding both the reading parts so as to be movable along a document, and means for selecting both the reading parts. The reading apparatus performs by one set of the apparatus total four modes of low resolution reading with respect to a light-impermeable document, high resolution reading with respect to the light-impermeable document, low resolution reading with respect to a large-sized light-permeable document, and high resolution reading with respect to a small-sized light-permeable document, such as a photographic film.

Reading apparatus

An image reading apparatus of the present invention enlarges and reads a small light-permeable document such as a photographic film. In the apparatus of the present invention, an image of a film is divided into strips and is projected on a part of a main-scanning direction of a line image sensor. The film is then moved in a direction corresponding to the main-scanning direction of the line image sensor, thereby reading the image of the whole area of the film.

Dual operational image reading apparatus

An information record/pickup head assembly for an optical information recording and/or reproducing apparatus using an optical information storage disk, comprising a stationary optical unit and a movable optical unit movable with respect to the information storage disk loaded, wherein the stationary optical unit emits a beam of light toward the movable optical unit which then re-directs the incident beam toward the information storage disk while returning to the stationary optical unit the beam of light reflected from the information storage disk. A focusing operation is carried out in the stationary optical unit.

Optical information record/pickup head assembly

A slit illumination system including a document support, a light source, a first elliptic mirror arranged at an opposite side to the document support with respect to the light source, an auxiliary mirror positioned at an opposite side to the first elliptic mirror with respect to the image light passage reflected by the document and a second elliptic mirror arranged at the side of the document with respect to the first elliptic mirror. The first elliptic mirror has a focussing line thereof positioned above or below the document and the second elliptic mirror has it positioned at the opposite side. The illumination light which is composed from the first elliptic mirror and from the second elliptic mirror through the auxiliary mirror has a flat top illumination intensity on the document.

Slit illumination system for copying machine and the like

A focusing device for use in micro film readers or the like for projecting micro images to give in-focus conditon exactly and readily. The present device includes a memory for storing a distance data representing the distance between an original and a projective lens at in-focus position thereof, and a sensor for measuring the distance between an original and the projective lens wherein the projective lens is moved to the in-focus position by a focusing motor in response to the distance data stored in the memory and a signal representing the measured distance generated from the sensor.
