摘要:
The present invention, to realize a compact projection-type television receiver set, provides a flattened projection-type cathode ray tube of a projection-type television receiver set. The projection-type cathode ray tube includes a phosphor screen panel, a phosphor screen formed on an inner surface of the phosphor screen panel, a face panel which is arranged to face the phosphor screen in an opposed manner, and an electron gun for forming an image on the phosphor screen, wherein the phosphor screen is inclined with respect to a tube axis on which the electron gun is arranged.

A vicinity part of a high-voltage feeding anode terminal, embedded in a funnel part and having a part thereof exposed on an outer wall surface of the funnel part, is washed with a hydrofluoric acid solution to remove a moisture-absorptive deposited substance adhering to the outer wall surface. According to a manufacturing method of this invention, anode leak failure due to unwanted discharge of the vicinity part of the high-voltage feeding anode can be restrained, and a projection cathode ray tube having an excellent display characteristic can be provided.

摘要:
The present invention provides a display device of high brightness which can eliminate brightness irregularities on a display surface while preventing the degradation of display quality attributed to an undesired electric field generated at the time of performing inverter driving of the cold cathode fluorescent lamps of a backlight. In a liquid crystal display device, a plurality of cold cathode fluorescent lamps of a backlight unit is arranged along a short axis of the display device. The cold cathode fluorescent lamp has a high-voltage electrode thereof connected to an inverter circuit and a ground electrode thereof connected to a ground. Further, the plurality of cold cathode fluorescent lamps arranged along the short axis have electrodes thereof arranged alternately between the high-voltage electrode and the ground electrode.

Multiplex communication equipment 1A used in a multiplex communication system, has a memory portion 12 memorizing the equipment number for the communication test. When there is an incoming call with reference to the same equipment number as one of the multiplex line 1A from the multiplex line 2A, the accommodation line portion 14a under setting a loop receives the incoming call and the communication test is done through a route for the communication test. When there is no accommodation line under setting the loop, the incoming call is rejected.
摘要:
Sensitivity of a velocity modulation device is increased and noise such as a leakage magnetic field and a leakage electric field from the device are reduced to thereby lower power consumed by the device. A cathode ray tube device and a television set each include a velocity modulation device on a cathode side of a deflection yoke. All or part of the circumference of a velocity modulation coil to modulate scan beam velocity is covered with material having an initial permeability of at least 10 at 2 MHz.
摘要:
A maintenance and supervising system and method for a multiplex communication system having mutually connected multiple pieces of multiplex communication equipment. A call controller executes call control by common channel signaling. A multiplexer multiplexes multiple communication data, and a fixed connection allocation device allocates multiplexed data within a multiplex circuit fixedly. A dynamic connection allocation device allocates multiplexed data within the multiplex circuit dynamically, and a piece of connection form switching equipment is provided. A piece of terminal equipment for maintenance and supervising is connected to one of the pieces of multiplex communication equipment. A call connection message is transmitted via common channel signaling, and the piece of maintenance and supervising equipment and the piece of multiplex communication equipment to be maintained and supervised are connected by securing a dynamic connection band in a multiplex circuit at the time of maintenance and supervising. The dynamic connection band is used for normal communication when not in use for maintenance and supervising.
摘要:
A Pb-base alloy containing 1 - 3% Sn and 0.5 - 3.5% Bi, allowing less than 2% Sb to be further contained, resists attack from acids formed in deteriorated lubricating oils. Either an alloy of Cu and the Pb-base alloy or a porous Cu mass impregnated with the Pb-base alloy is a highly corrosion-resistant bearing material, and the Pb-base alloy serves also as a direct overlay on a Cu-base bearing material due to negligible heat diffusion of Sn from the alloy.
摘要:
Pre-shipment data includes, in addition to product data representing features of the products P, data that associate product identification data for identifying each of the products P included in the product data with package identification data for identifying a carton C containing the products P. A management warehouse system 3a assumes that products corresponding to the product identification data associated with the package identification data have arrived if the package identification data included in barcode 52 scanned by a reader device exist in the pre-shipment data transmitted from the management warehouse system 3a.
