Semiconductor memory device

Abstract: A command analyzer 160 determines whether or not a first write command after power-on is issued. A new block reserve determinator 170 determines that a new physical block is reserved, in a case where the command analyzer 160 determines that first writing command after power-on is issued and the physical block corresponding to a logical address at which a host device requests transmit is in a written state. At this time, the semiconductor memory device writes data to the new physical block. Thereby, data written before power disconnection does not been destroyed.

Production process of liquid crystal display panel, seal material for liquid crystal cell and liquid crystal display

Abstract: This invention relates to a liquid crystal display apparatus formed by sealing a liquid crystal between two substrates having electrodes and an alignment film with a seal material, the production process comprising the steps of attaching two substrates in a vacuum, compressing under atmospheric pressure to provide a uniform cell gap, a temporary hardening process of the seal material by ultraviolet ray irradiation and a main hardening process of the seal material by heating, wherein a radically polymerizable curing resin is used in the liquid crystal seal material. The method provides a liquid crystal display panel having a uniform cell gap, without dislocation of the alighnment between substrates, or discharge of uncured component of a seal material to the liquid crystal, capable of having a seal material firmly attached to the substrates even at panel corner portions, and having an excellent straightness and moisture resistance of the seal material.

Stereoscopic computer graphics image generating apparatus and stereoscopic TV apparatus

Abstract: The stereoscopic CG image generating apparatus and a stereoscopic. TV apparatus, has a projection transformation section which, based on three-dimensional structural information describing a three-dimensional shape of an object, generates a plurality of two-dimensional projection models as viewed from a plurality of viewpoints, a distance information extraction section which generates a camera-to-object distance information used for calculations in the projection transformation section, and a camera parameter determining section which, based on the output of the distance information extraction section, the screen size of a stereoscopic image display device for displaying finally generated two-dimensional projection models, and a viewer's viewing distance, determines camera parameters so that stereoscopic CG images will be brought within the viewer's binocular fusional range. According to the thus constructed stereoscopic CG image generating apparatus and stereoscopic TV apparatus, proper camera parameters (focal length or field of view, camera spacing, and converging point) are determined based on the camera-to-object distance information, the magnitude of parallax of the generated stereoscopic CG images on the display device (or in a window on the display screen), and the viewing distance, so that easy-to-view stereoscopic CG images are automatically generated regardless of the display size, and by horizontally translating left-eye and right-eye images, binocular parallax of displayed images is automatically brought within the viewer's binocular fusional range regardless of the size of a stereoscopic display used.

Refrigerating cycle device

Abstract: A refrigerating cycle device using carbon dioxide as refrigerant capable of solving such a problem that when a receiver is installed against a low pressure, a cost and a volume are increased by a pressure resistant design to assure safety, wherein a first pressure reducing device (12) and a second pressure reducing device (15) are operated to vary the refrigerant pressure of a first heat exchanger (13) so as to regulate the refrigerant hold amount of the first heat exchanger, whereby since the unbalance of the amount of refrigerant between cooling and heating/dehumidifying can be reduced, the refrigerating cycle device can be efficiently operated with a downsized receiver or without installing the receiver.

Method and device for inputting information for a portable information processing device that uses a touch screen

Abstract: An input device comprising LCD panel 106, tablet 108 which is set thereon, wherein representative keys are displayed on LCD panel 106. When pen 109 touches a key, the key is expanded. If pen 109 continues pressing the key, the displayed key changes to its related key. When pen 109 is lifted up from tablet 108, a key corresponding to a position on tablet 108 from which pen 109 has been lifted up is determined as an input key.
