  • Publication number: 20070034301
    Abstract: A steel-made rolling-contact shaft with a joint claw improved in both the rolling contact fatigue life at the raceway and the static fracture strength (torsional strength) at the claw includes a joint claw at one end, and has a portion of the outer cylindrical surface functioning as a raceway of a needle roller qualified as a rolling element of a needle bearing. The joint claw is subjected to tempering by induction heating. A nitrogen-enriched layer is formed at the surface layer of the rolling-contact shaft with a joint claw. The grain size number of austenite grains in the nitrogen-enriched layer exceeds number 10. The hydrogen content of the rolling-contact shaft with ajoint claw is not more than 0.5 ppm.

  • Patent number: 7153627
    Abstract: A negative-working CTP plate which is superior in resolution and printing resistance of the image area of a press plate is provided, which is obtained by forming a latent image on a heat-sensitive layer in a heat-sensitive lithographic printing plate comprising a substrate having a hydrophilic surface and a heat-sensitive layer made of an alkali-soluble polymer formed on the surface of the substrate, using heat generated upon irradiation with laser light, and developing the heat-sensitive layer using an alkaline developing solution. In the heat-sensitive lithographic printing plate comprising a substrate having a hydrophilic surface, and a heat-sensitive layer made of an alkali-soluble polymer formed on the surface of the substrate, an advancing contact angle (?f1) of the surface of the heat-sensitive layer with water at 25° C. is within a range from 70° to 110°, a receding contact angle (?b2) of the surface of the heat-sensitive layer with water at 25° C. after heating at 150° C.

  • Publication number: 20060264207
    Abstract: When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover.

  • Publication number: 20060249512
    Abstract: A uniquely shaped gasket (6) suitable for a container for storage of substrate plates requiring precision packaging. When such plates are stored into a container body (2), and a container lid (3) is closed and then a lid lock is applied, a gasket's outward ledge (6b, 6c, 6d) is pressed downward by an outward adjacent surface (3f) and deformed; consequently, the end of the ledge's tip (6d) will extend to fall in a seal channel (2d), in other words, to abut on a sectionally downward concave (2d), wherein the gasket (6) still keeps its elastic resiliency. As a result, if an air pressure difference occurs, the tip end (6d) will shift its abutting point. While the tip end (6d) moves, a minimum gap between the tip end (6d) and the channel surface (2d) occurs, and this gap will act as ventilation route to equalize the air pressure difference.

  • Patent number: 7123246
    Abstract: The invention provides a display device which is capable of adjusting the image refresh rate to an optimal value regardless of the type of image data, and thus has low power consumption. The display device includes a liquid crystal panel for displaying images, a liquid crystal controller for refreshing images displayed in the liquid crystal panel according to an image data signal, and a CPU for inputting the image data signal to the liquid crystal controller. In the display device, the CPU has a discrimination section for discriminating whether the image data is a moving image or a still image based on an input interval of the image data from the CPU to the liquid crystal controller, and the liquid crystal controller has an image refresh demand signal generation circuit for changing the image refresh rate of the liquid crystal panel based on the result of discrimination by the CPU.

  • Patent number: 7052823
    Abstract: A method of manufacturing an electroconductive film subject to edge curl due to volume contraction after baking includes sequentially repeating a film-forming step of forming a film containing a photosensitive material and an electroconductive material therein and an exposure step of irradiating a light onto a desired region of the film for a plurality of times to laminate the films. The latent images of the respective layers are integrated. The resulting latent image is developed by removing a non-latent image region of the laminate film after the laminate film is formed. Finally, the developed image is baked. The sequential repetition of the film-forming step and the exposure step act to counteract edge curl formed by volume contraction after baking.
