摘要:
A liquid crystal device is disclosed wherein a pair of liquid crystal supporting plates each having a molecular alignment controlling film formed thereon through the Langmuir-Blodgett method singly orlaminatedly a monomolecular film having as a main component a polyamide compound having a long-chain alkyl substituent in its side chain and a property to overspread a surface of water to form a monomolecular film is oppositely held via a spacer which is adhered on the side on which the molecular alignment controlling film is formed, and a liquid crystal material is injected and held into the space produced between the films thus oppositely held to each other thereby to align the molecules of liquid crystal to the azimuth parallel to the dipping direction of the substrate. A liquid crystal device thus manufactured exhibits a uniform and indefective molecular alignment condition.

A method of producing an optical recording medium according to the present invention includes the steps of forming a recording film on a transparent substrate, recording signals in the form of perforated pit rows on the recording film by a laser beam, and forming a reflection layer on the recording film on which the pit rows have been formed. The recording film is bleached after recording or the laser beam used for recording is selected to have a wavelength different from that of a laser beam used for reproducing so that the recording film is transparent to the laser beam used for reproducing.
摘要:
There is provided an optical disc of high reliability, with the recording film protected from deterioration. The optical disc of this invention is produced by forming a tellurium suboxide film or optomagnetic recording film on a substrate made by injection molding from a polycarbonate resin. The substrate is made from a polycarbonate resin containing a phosphite ester-based antioxidant in a specific low amount.
摘要:
A film condenser formed of a solderable metal foil composed on one member 1 selected from the group consisting of copper, tin, and aluminum having a heat resistant plastic film 2 coated on one surface and a vapor-deposited metal film 3 on the surface of the heat resistant plastic film facing away from the metal foil. Two lead wires each having a part bent in the shape of a V or u with the open end facing laterally of the length of the wire and having a size to prevent solder in a molten state from flowing out of the bent part during soldering due to the surface tension of the molten solder are soldered to the other surface of the metal foil and to the surface of the metal film facing away from the plastic film.

摘要:
In a jitter correction method and circuit, combination data combined by adding, to referenced data, an end bit of data 1 clock prior to and a head bit of data 1 clock subsequent to the referenced data is sequentially generated. Each bit of the combination data is sequentially referred. When a change between a referenced bit and a bit directly adjoining the referenced bit is detected, and when a number of references reaches a multiplication number of the oversampling and a change between at least three adjoining bits including the referenced bit is not detected, change position display data regarding the directly adjoining bit as a change bit of the referenced data is generated and the number of references is initialized. When the change is not detected and the number of references does not reach the multiplication number, the number of references is incremented. All the change bits are extracted from the referenced data and the change position display data, and a data reproduction is performed corresponding to the multiplication number.

Disclosed is a color image-formable material for forming and transferring a color image. The color image-formable material has a support, a cushion layer provided on the support and color light-sensitive layer containing a light-sensitive composition and a coloring agent provided on the cushion layer. It gives a transferred image by forming a color image portion by imagewise exposure and developing treatment and then transferring the color image portion alone to an image-receiving material. The cushion layer has a hardness of 40 to 85 and a thickness of 15 .mu.m to 100 .mu.m. A process for preparation of the color image-formable material is also disclosed.
摘要:
The setting and phase adjusting apparatus for synchronous multiplex communications is provided which adjusts phase differences of main signals caused between a plurality of synchronous multiplexing sections and a line setting section during line setting, in which to reduce the scale of circuitry of the line setting section in a transmission device for carrying out multiplexing and line setting on large-capacity signals, a plurality of pointer modifiers are arranged on a shelf on which the line setting section is arranged. The pointer modifiers connect the line setting section to the respective synchronous multiplexing sections. The pointer modifiers are supplied with multiplexed signals of respective signal series whose data head positions are shifted from one another. The head positions of these signals are synchronized with a timing signal from a timing generator by the pointer modifiers. Line switching is then effected by time switches and a space switch.
