An optical path control apparatus includes an oscillating part. The oscillating part has an optical part on which light is made incident, a first oscillating part for supporting the optical part, and a second oscillating part for supporting the first oscillating part in an oscillatable manner by a first shaft part and being supported on a support part in an oscillatable manner by a second shaft part. The optical path control apparatus includes a first actuator configured to oscillate the oscillating part about a first oscillation axis including the first shaft part as a support; and a second actuator configured to oscillate the oscillating part about a second oscillation axis including the second shaft part as a support. The first oscillation axis crosses the second oscillation axis. The torsional rigidity of the second shaft part is higher than the torsional rigidity of the first shaft part.

Optical path control apparatus and display apparatus

A projection system includes a projection device configured to simultaneously project a first image light for a first image and a second image light for a second image; an eyeglass-type device which is to be worn by a user and configured to include a first optical module configured to transmit the first image light projected by the projection device and a second optical module configured to transmit the second image light projected by the projection device; and at least one light source unit configured to emit a source light of wavelengths that are in a visible light band and have a transmittance equal to or less than a predetermined value in both the first optical module and the second optical module.

A display controller includes: an upper limit luminance value acquisition unit configured to acquire, for pixels of display devices, an upper limit luminance value of an absolute luminance value; a set luminance value setting unit configured to set a set luminance value so that the set luminance value is smaller than a maximum value among the upper limit luminance values; an input luminance value acquisition unit configured to acquire an input luminance value based on input data; an output gradation value generation unit configured to generate an output gradation value based on the input luminance value and the set luminance value; and an output controller configured to output the generated output gradation value, wherein the output gradation value generation unit is further configured to generate the output gradation value so that an output luminance value is equal to or smaller than the set luminance value.

A signal processor converts an input 3D image signal into a signal in which a left-eye signal and right-eye signal are rearranged temporally alternately. A driver of a liquid crystal display element includes a sub-frame data generator configuring all the sub-frames with step bit pulses and generating sub-frame data by using a drive gradation table in which the last sub-frame reaches a drive state when a drive gradation is '1' and the number of sub-frames reaching the drive state is increased one by one toward ahead of a sub-frame which has already reached the drive state, every time the drive gradation is increased by one. The liquid crystal display element is driven by the driver. An illumination optical system causes illumination light to enter into the liquid crystal display element. A projection lens projects modulated light emitted from the liquid crystal display element.

Three-dimensional image display apparatus

An aspheric mirror has an aspheric reflective surface symmetrical with respect to an optical axis that goes through the reflective surface and a reference plane provided in the reflective surface. The optical axis may go through the reflective surface at a non-center position on the reflective surface. The reference plane may be perpendicular to the optical axis. The reference plane may be flat enough for a beam to be reflected from the reference plane in almost specular reflection when emitted to the reference plane.

A plasma process end point determination method comprises the steps of measuring a physical quantity in a circuit for producing a plasma within a reaction chamber, and determining a plasma process end point on the basis of an inflection point of the measured physical quantity in relation to the passing of time.

Plasma process end point determination method and apparatus, and plasma evaluation method and apparatus

A tape loading mechanism is designed for an apparatus operating on a magnetic tape at least partially in a tape cassette and including a rotary drum. In the tape loading mechanism, first tape guides move to draw a portion of the magnetic tape from the tape cassette. In addition, second tape guides move to wrap the magnetic-tape portion, which is drawn from the tape casette, in a helix around the rotary drum. The first tape guides and the second tape guides cooperate with each other to hold substantially constant a length of the magnetic-tape portion which is drawn from the tape cassette.
