  • Publication number: 20130335901
    Abstract: The present invention is relates to a mobile electronic apparatus including a packaging structure configured to evade destruction of a display part against an impact applied from outside. In a mobile electronic apparatus (1), if an impact is applied from a direction (B), a casing composed by a casing section (51), a bottom cover (20) and a cover (60) become deformed. If the casing is deformed, a hollow section (100) is deformed at the same time. A key rubber (30) becomes deformed to follow the portions becoming deformed. By the key rubber (30) becoming deformed, the impact applied from outside may be absorbed, and impact exerted to LCD module is reduced.

  • Patent number: 7911697
    Abstract: A lens includes a front group including a plurality of lens groups; and a rear group that is provided on an image side of the front group and that includes a negative lens and a positive lens. The positive lens has a flat lens surface on its image side, and is tiltable about a spherical center of its object side lens surface that is convex on the object side. When a lens system is inclined, the positive lens is tilted in relation to the optical axis of the lens system based on: a focal length of the overall lens system; an angle of the optical axis of the lens system after being inclined in relation to the optical axis before being inclined; a distance between the image side lens surface of the positive lens and the image plane; and a refractive index of the positive lens.

  • Patent number: 7668335
    Abstract: It is an object of the present invention to provide a communication device, a digital signature verification method, and a digital signature generation method, in which the memory usage efficiency is improved without confidential information required for the verification or generation of a signature being easily leaked to the outside. The Java application judges whether signature verification is required for the received signature target data. When judging that signature verification is required, the Java application outputs the received signature target data to the PKI of the platform. The PKI verifies the signature that has been added to the data output by the Java application and performs signature generation, and then notifies the Java application.

  • Publication number: 20090008485
    Abstract: Crushing finely the chipped rubber such as that of waste tire is done by further small number of crushers, and the capture rate of the target size of the rubber particles is improved. With a crusher which finely crushes the chipped rubber (G) such as that of waste tire, the chipped rubber (G) is supplied to a crusher (10a) structured by a rotating roll (12) having relatively rough groove pitch and pluralities of fixed blades (14) each of which has pluralities of grooves forming crushing edges, thus conducting crushing. The rubber particles (G) discharged from the crusher (10a) are again supplied to the crusher (10a) to repeat the crushing to conduct rough-finishing operation. Then, thus roughly-finished rubber particles (G) are treated by similar crushing operation using a rotating roll (10b) having relatively small groove pitch to conduct finish treatment. The finely-crushed rubber particles are classified using a sieve (16) to specified size ranges.

  • Patent number: 5529475
    Abstract: An extruder for rubbery materials includes an extruding unit having a die holder. A horizontal lead-through groove is formed in the die holder for slidably arranging a die plate therein. A rubbery material is extruded through the die plate in a predetermined direction to form a strip rubber member with a predetermined cross-section. A storing device is arranged on one side of the extruding unit, for temporarily storing a plurality of die plates to be subsequently used on a storing table in accordance with a predetermined use priority. The storing device delivers a next die plate from the storing table to a waiting position along the extension line of the lead-through groove. A moving device is operative when the die plates are to be changed, for moving a current die plate together with the next die plate at the waiting position, along the lead-through groove in a direction toward the other side of the extruding unit.
