摘要:
A backlight unit having a LED light source includes a light guide plate partitioned in areas each having a tapered shape formed of a thick portion and a thin portion. The light guide plate is formed such that a thick portion and a thin portion are repeated at certain intervals, and the repeated thick portions and the repeated thin portions gradually decrease in thickness. The LED light source is attached to a lateral side of each thick portion. Grooves are formed in the light irradiation direction of the LED light source and in a direction perpendicularly intersecting the light irradiation direction. Each of the grooves is formed in an concave shape (V-shape or trapezoid-shape). There is a relation 0.2/30

摘要:
Program content is easily selected on a playback apparatus having a plurality of program content recording locations.A video recording management server (11) manages program IDs, the video recording condition of program content on a television apparatus (10), and recording location information indicating on which server each program content is recorded, in association with each other as program management information. The television apparatus (10) displays an electronic program guide (100) in which past and future programs are displayed integrally, and displays a video recording complete mark (RM) for programs previously recorded on a user content server (13). On the other hand, when an instruction to play back program content is made in the electronic program guide (100), the television apparatus (10) receives the program content from a server designated from the video recording management server (11) to perform streaming playback. Thus, the television apparatus (100) can perform video recording and playback of program content desired by the user by means of the electronic program guide (100), without making the user specify a program content recording location.
摘要:
A plurality of backlight blocks are aligned, each block includes light sources and a unit light guide plate for guiding light from the light sources to the side of a liquid crystal panel, unit diffusion patterns are formed in a zigzag alignment on the unit light guide plate and another diffusion pattern is formed on the back of the unit light guide plate. One side of the unit light guide plate is defined as a light entrance surface and LEDs as the light sources are aligned along the light entrance surface to satisfy p≧a≧c where a indicates the size of the unit diffusion pattern in a direction orthogonal to an exit optical axis of the LEDs, c indicates the size of an LED emission surface in the direction of alignment of the LEDs, and p indicates the pitch of alignment of the light sources.

A method for driving an AC type plasma display panel includes the steps of performing initialization at least once for each frame so as to clear binary setting of wall charge quantity in a screen by discharge except for micro discharge in which electrodes covered with a plurality of fluorescent materials become cathodes, and performing special initialization at frequency of once for M frames, where M=two or more, so as to erase unnecessary wall charge in the screen by discharge in which electrodes become cathodes and that is stronger than the discharge in the initialization.

An artificial elbow joint of constraint type that makes it easier to assemble a joint section even when a surgery for replacing an elbow joint is in process, and is effective in improving the safety of surgery and reducing the time taken to complete the surgery. The artificial elbow joint of the present invention comprises: a humeral component comprising a humeral stem, a shaft and a anterior flange; and an ulnar component comprising an ulnar stem and a sleeve, wherein the shaft of the humeral component is fitted in the sleeve of the ulnar component rotatably. The sleeve has a slit-like sleeve opening a width of which is smaller than an outside diameter of the shaft and having a flexible sleeve insert on inner surface of the sleeve to be contacted with the shaft whereby the sleeve is fitted with a snap into the sleeve through the sleeve opening, and a centerline of the sleeve opening is oriented toward an anterior cubital region at an angle between 45 to 90 degrees with respect to a downward direction of an axis of the ulnar stem.

A direct color thermal printer includes a heating element array for yellow, a heating element array for magenta, and a heating element array for cyan to perform the thermal printing on each of recording areas in color thermosensitive recording paper. When one of the heating element arrays, the heating element array for yellow, for instance, faces a blank area of the color thermosensitive recording paper, the heating element array for yellow starts a blank area recording to thermally print the blank area. Thereby, all of the heating element arrays constantly remain in a state of thermal printing, so that variations in recording density, which is caused by the load fluctuations in the power supply, does not occur.
摘要:
An interlace-type PDP is driven by an improved driving method so as to achieve a greater operating margin, higher resolution, and higher brightness. The interlace-type PDP is driven using odd and even frames in such a manner that the cells are grouped into cell groups such that each cell group includes two or three cells which are adjacent in a direction crossing the electrode pairs, and the cells are driven in units of cell groups. The grouping of cells is performed differently for even and odd frames such that, in one type of frame, locations of two or three cells grouped into each group are shifted by one cell, in the direction crossing the electrode pairs, from the locations of cells grouped together in the other type of frame.
