摘要:
An optical pickup apparatus is constructed of an objective lens for condensing a light beam emitted from a light source toward an optical recording medium, and a convex lens arranged between the optical recording medium and the objective lens in which a surface thereof upon which the luminous flux projected from the objective lens is incident is a convex spherical surface with a radius of curvature which is a predetermined value, and another surface thereof which is located near and opposite to a surface portion of the optical recording medium which is a plane. With this arrangement, a tolerance with respect to decentering of the convex lens in connection with the optical axis of the objective lens is increased, so that an occurrence of aberration is reduced.

Defined information is generated for each of screen information, layout information, and media information in response to an operator's entry when an environment is defined. When a change is monitored in predetermined position information using a screen monitoring unit during the actual operation, a character string to be displayed with media information is extracted according to the contents of the defined information. After media information corresponding to the character string, that is, the name of layout to be used and actual media information is obtained, and the position and size of a frame and the display format of the media are further obtained, each depending on the name of layout to be used, media information corresponding to the character string to be displayed with media information is displayed. Thus, character string information can be displayed with multimedia information added together only by mounting the multimedia information add-on system without restructuring an existing system.

In a CMIS device having a semiconductor substrate including a first N-type region and a P-type region, a second P-type region is formed within the first N-type region, and a second N-type region is formed within the first P-type region. Also, a third N-type region is formed within the second P-type region, and a third N-type region is formed within the second N-type region. An N-channel transistor is formed by the first N-type region as a drain, the second P-type region as a channel, and the third N-type region as a source. A P-channel transistor is formed by the first P-type region as a drain, the second N-type region as a channel, and the third P-type region as a source.

An improved liquid crystal device is described. The distance between a pair of substrates is kept constant by means of spacers interposed therebetween. The spacers consist of two kinds of spacers. One kind of spacer is fusible and functions to prevent the distance from expanding. The other kind of spacer is non-fusible and functions to prevent the distance from contracting.

摘要:
A method of filling a liquid crystal device including a pair of parallel substrates having external surfaces with a liquid crystal material is set forth. The liquid crystal device is filled by disposing the liquid crystal device in a vacuum chamber between a pair of opposed parallel plates, evacuating the vacuum chamber, supplying the liquid crystal material to an inlet of the device, elevating the pressure in the chamber to allow the liquid crystal material to enter a space formed between the parallel substrates through the inlet by virtue of a differential pressure between the inside and the outside of the liquid crystal device, and applying opposed pressure with the parallel plates to the external surfaces of the parallel substrates respectively in order to form a uniform liquid crystal device. With the external pressure being applied to compensate for the expansion of the liquid crystal device during the elevation of the pressure within the vacuum chamber.

An improved liquid crystal device and manufacturing method for same are described. In the device, a pair of substrates, between which a liquid crystal layer is disposed, is joined with pillars inbetween functioning as spacers which are provided of photocurable resin by photolithography. With this structure, the spacers can be in surface contact with the inside surfaces of the substrates on which electrode arrangement and active devices are formed.

A copying machine, including a photosensitive drum; a corona charger; an exposure device for exposing the photosensitive drum to an optical image of an original; a developing unit for developing a toner image on the photosensitive drum; a transfer corona charger for transferring the developed toner image to copy paper; a device for mechanically separating the imaged copy paper from the photosensitive drum; and a system for cleaning the drum after the image transfer, which includes an eraser lamp disposed adjacent the copy paper delivery side of the transfer corona charger at a position for illuminating copy paper from the rear side thereof upon image transfer thereto, and a control unit for controlling the operation of the transfer corona charger and the eraser lamp, thereby assuring smooth separation of copy paper after image transfer and efficient transport of the paper.
摘要:
An operation indicating device for electromagnetic relay which comprises a working member interlockable with an armature of an electromagnetic relay and extending into a space above a yoke, and an indicating member coupled to the working member and having an axis rotatably supported in the space above the yoke, the indicating member having a recognizable indicating portion and being rotatable by the working member interlocking with the armature during the operation of the armature, the indicating portion of indicating member thus rotated arriving at a position corresponding to an indication window formed in a case cover.When the armature is activated, the working member, interlockable with armature, is activated and the indicating member coupled to the working member is rotated around a supporting shaft serving as the fulcrum. The indicating portion of the indicating member moves to a position located immediately below an indication window formed in the case cover and the operation of the electromagnetic relay can be visibly confirmed.
