A lock device is provided that easily enables attachment and detachment of an expansion unit to and from a computer body such as of a notebook personal computer. The lock device includes a pivotal piece near an expansion-unit insertion slot in the computer body, a first element that extends along a moving direction of the expansion unit, which moves in an extending direction by the pivoting action of the pivotal piece, and includes a press portion that presses the expansion unit when the expansion unit is to be released, and a second element engageable with an engagement portion of the expansion unit, the second element being disengageable from the engagement portion when the first element moves.

The television signal recording/reproducing system digitally records and reproduces television signals composed of a luminance signal, a chrominance signal and a resolution compensation signal included in predetermined television scanning lines. The system includes a Y/C separating circuit for separating the luminance signal Y from the chrominance signal C and a decoder for decoding the color signal into color difference signals C.sub.B, C.sub.R. One of the color difference signals C.sub.B, C.sub.R is combined with the resolution compensation signal, and a digital video signal recorder digitally records the combined resolution signal and the color difference signal. In this manner, the resolution compensation signal is accurately recorded.

A local region image tracking apparatus continuously tracks an arbitrary local region within a search image that is described by search image data by comparing the search image data to be subjected to a tracking process out of input image data picked up by image pickup means with reference image data related to the arbitrary local region. The local region image tracking apparatus includes an image data bus transferring the input image data from the image pickup means, and a plurality of correlation tracking processors coupled in parallel to the image data bus and respectively capable of independently carrying out the tracking process with respect to at least one search image, where the tracking process with respect to one or a plurality of search images is distributively carried out by the correlation tracking processors.
摘要:
A super-resolution optical head device in which a first super-resolution spot having a diameter smaller than that of a diffraction limit is formed on a recording medium by modulating beams emitted from a laser light source includes an optical system, an optical separator and a plurality of optical detectors. By the optical system, the laser beams reflected from the recording medium are converged and a second super-resolution spot is reimaged. The optical separator is constituted by a reflection-type pinhole, a diffraction-type pinhole, a refraction-type pinhole, a reflection-and-absorption type pinhole, or a set of a reflection-type pinhole and a reversed-type pinhole, which is placed at the reimaged position and optically separates the second super-resolution spot into a main beam component and a sidelobe component. The optical separator leads to the optical detectors the main beam component and the sidelobe component independently from each other. The device enables to easily obtain reproduction signals with little deterioration caused by the sidelobe component.

A cache control method and a rotary storage device are capable at a low cost, of improving the hit rate and minimizing the processing time in the event of a miss hit. The rotary storage devices includes a plurality of disk units, an upper-level interface circuit, a cache controller, a cache memory, and a control processor. In each disk unit, the storage area of each disk is subdivided into an ordinary user data area and a secondary cache data storage area including a group of consecutive cylinders. Data which has overflowed from the cache memory is sequentially written in the secondary cache data storage area so as to be later transferred therefrom to areas of the user data area according to addresses inherent thereto when traffic of upper-level input/output processing is relatively low. In the case of a miss hit of the cache memory during a data read operation, access operations are performed first to the secondary cache data storage area and then to the user data area.
摘要:
A liquid crystal electro-optical device having gettering means therein and a method for manufacturing such a liquid crystal electro-optical device are disclosed. For example, in a liquid crystal panel disposed in the device, polyvinyl carbazole film is formed as the getting means on at least one of a pair of substrates, and the film has a function to absorb ionized impurities existing in liquid crystal disposed in the device. In virtue of the film, ionized impurities in the liquid crystal layer are decreased, and by heating the liquid crystal panel, the function of the polyvinyl carbazole film, i.e. the function to absorb ionized impurities, is enhanced. Consequently, a liquid crystal electro-optical device free from after-image which was a problem in conventional liquid crystal display devices can be obtained.
摘要:
A method for manufacturing a liquid crystal device in which a pair of substrates are placed in a vacuum chamber, with at least one inlet port provided for communicating with an inner space between the pair of substrates. The vacuum chamber is evacuated and a material including liquid crystals is supplied to the inlet port. The pressure of the chamber is then elevated such that the liquid crystal and other materials are introduced into the space between the pair of substrates by the use of differential pressure between the inside and outside of the space between the substrates. The material including the liquid crystals is maintained at a sufficiently high temperature such that the liquid crystals exhibit isotropic phases.

An improved method of filling a liquid crystal device with a blended ferroelectric liquid crystal material is disclosed. The method includes the step of disposing the blended ferroelectric liquid crystal material in an inner space formed in the liquid crystal device, with the temperature of the blended liquid crystal being maintained during the disposing step at a temperature higher than the transition temperature of any constituent of the blended liquid crystal material such that the blended liquid crystal material is transformed in its isotropic phase.
