  • Patent number: 8710666
    Abstract: A semiconductor device which can prevent a deterioration in the electrical properties by preventing sputters generated by laser welding from adhering to a circuit pattern or a semiconductor chip and a method for fabricating such a semiconductor device are provided. A connection conductor is bonded to a copper foil formed over a ceramic by a solder and resin is injected to a level lower than a top of the connection conductor. Laser welding is then performed. After that, resin is injected. This prevents sputters generated by the laser welding from adhering to a circuit pattern or a semiconductor chip. As a result, a deterioration in the electrical properties can be prevented.

  • Publication number: 20130256730
    Abstract: [Problem] To provide a light-emitting device which does not undergo the deterioration in luminous efficiency associated with the long-term use. [Solution] A light-emitting device (1) comprises a light-emitting element (10) which can emit blue light and a phosphor (2) which is composed of a single kind of single crystal and can emit yellow light upon the irradiation with the light emitted from the light-emitting element (10) which serves as excitation light. Thus, it becomes possible to prevent the deterioration in luminous efficiency associated with the deterioration in a binder or the like compared with a light-emitting device which utilizes multiple kinds of granular phosphors, because any binder for binding phosphors to each other is not required in the light-emitting device (1).

  • Patent number: 8400469
    Abstract: During execution of an engine application by an engine unit, a host unit determines a region for host display upon a display screen, wherein the host unit determines the display contents, according to the usage direction of the display screen employed. Subsequently, the unit creates a host image; the unit generates an engine application image, when the operation of the engine application starts. A display image generation means then generates an image during engine application execution wherein the host image and the engine application image are overlapped, so that, in the region wherein the region for host display and the region for engine display are superimposed, priority is given to the engine application image. Thus, along with it being possible to build the device as a whole in a more compact manner, it is also possible to ensure the convenience from the point of view of the user.

  • Patent number: 8375079
    Abstract: An application load unit of a host unit loads an application main body of an engine application which has been acquired to an engine unit. Subsequently, when an execution command for the application main body is issued by the user, an execution decision means within an application execution control unit of the host unit refers to application management information, and decides whether or not it is possible to execute the application main body. If the result of this decision is affirmative, an execution command transmission means within the application execution control unit sends an execution command for the application main body to the engine unit. As a result, processing related to the engine application is apportioned between the host unit and the engine unit in an appropriate manner.

  • Patent number: 8301185
    Abstract: Whenever, there occurs a predetermined event which occurs periodically, a host section which includes a host processor 31, makes a judgment of whether or not it is an engine-mode state in which an engine section 40 is executing an engine application, and whether or not it is estimated that the engine-mode state will be continued. When this judgment result is affirmative, the host section notifies to the engine section 40, information which the host section has collected after the previous notification, and which is to be notified periodically to the engine section. As a result of this, at a periodic timing called as an occurrence of a predetermined event, periodic notification data is notified from the host section to the engine section 40.
