摘要： In a case where reception power in a radio access point is high by external noise, the normalcy of the radio access point is tested. In order to judge the normalcy of the radio characteristic of the radio access point, a test is performed through the calling connection between a testing access terminal in the radio access point and a predetermined device. An RSSI is measured before and after the transmission of a test signal. When the RSSI exceeds a threshold value, the path loss of a reverse link connected from the radio access point to the testing access terminal is increased by an attenuator. Then, reception power in the testing access terminal decreases. Thus, initial transmission power in accordance with the reception power from the testing access terminal is raised and the calling connection of the testing access terminal can be performed even under the external noise.

摘要： Detailed model data having numerous polygons and rough model data having fewer polygons are prepared for one object. A rectangular parallelepiped including the entire object is defined as a bounding box. A virtual three-dimensional space is perspective-transformed to divide an image-drawing field, which is an image drawing range, into a far image-drawing field and a near image-drawing field according to a distance from a viewpoint of virtual camera. When at least a part of the bounding box is included in the far image-drawing field, polygons of rough model data included in the far image-drawing field are drawn in a frame buffer. When at least a part of the bounding box is included in the near image-drawing field, polygons of detailed model data included in the near image-drawing field are drawn in a frame buffer.

摘要： By using a gas diffusion layer for a fuel cell comprising a fabric comprising a warp thread and a weft thread which are made of carbon fiber, wherein the distance X between adjacent intersections where the warp and weft threads cross each other and the thickness Y of the fabric satisfy the equation: 1.4≦X/Y≦3.5, the present invention reduces the surface asperities of the substrate and prevents a micro short-circuit resulting from the piercing of the polymer electrolyte membrane of the fuel cell by the carbon fibers of the fabric so as to improve the characteristics of the fuel cell. In order to further prevent the piercing of the polymer electrolyte membrane by the carbon fibers of the gas diffusion layer substrate, the rough surface of the carbon fabric is smoothed by: (1) applying a clamping pressure of 1 to 20 kgf/cm2 to the contact area between each electrode and each conductive separator plate of the fuel cell; or (2) heating the gas diffusion layer surface before the gas diffusion layer is disposed onto the polymer electrolyte membrane.

摘要： A method of degaussing a cathode ray tube where two pairs of degaussing coils are arranged with one pair located at the top and bottom and the other to the right and left of the cathode ray tube after impaired color purity correction process of an electron beam has been carried out for the cathode ray tube using a magnetization process with a magnetization including an anticipated amount of degaussing for the cathode ray tube when the cathode ray tube is incorporated in a display device. The degaussing of a magnetic material within the cathode ray tube is then carried out with the anticipated amount of degaussing using the degaussing coils. In this way, a color cathode ray tub with no impaired color purity can be provided because the cathode ray trajectories corrected by magnetization in the magnetization process is not easily changed during use after incorporation in the display device.
