  • Patent number: 10707389
    Abstract: A light emitting device includes a light emitting surface, a back surface arranged on an opposite side of the light emitting surface, a mounting surface arranged between the light emitting surface and the back surface, and includes a light emitting element, a light shielding member, first and second terminal coating films, and first and second electrically conductive members. The light emitting element has first and second electrodes arranged on the second main surface. The light shielding member covers the lateral surface of the light emitting element and does not cover the first main surface of the light emitting element. The first and second terminal coating films are electrically connected to the first and second electrodes respectively, and arranged continuously on the back surface and the mounting surface of the light emitting device. The first and second electrically conductive members are in contact with the first and second electrodes respectively.

  • Patent number: 7843633
    Abstract: The present invention relates to a laser processing apparatus which can be miniaturized and has a structure for achieving effective protection of the fiber laser light source. The laser processing apparatus comprises a fiber laser light source, a collimator, a spatial filter, an optical isolator, and a condenser lens. The optical isolator emits laser light from the collimator laser light in parallel to the direction of incidence of the laser light, and emits return light from the condenser lens at a predetermined angle with regard to the direction of incidence of the return light. The spatial filter comprises a pair of condenser lenses disposed such that the focal point is formed therebetween, and a pinhole mask disposed such that the pinhole is located at the focal point. At least, a part of the return light emitted from the optical isolator is blocked by the pinhole mask of the spatial filter.

  • Patent number: 7305743
    Abstract: A piezoelectric ceramic compound expressed by a basic formula of Pb(Zn1/3Nb2/3)aZrxTiyO3 (where 0.90<a+x+y<1.00) is provided. The starting materials for the piezoelectric ceramic compound are calcined. The calcined material is milled to provide powder. A formed body containing the powder is provided. The formed body is degreased at a temperature having the formed body not sintered. A sintered body is provided by sintering the degreased body. The sintered body is heated to subject the sintered body to predetermined heat treatment. The sintered body subjected to the predetermined heat treatment is polarized to provide the sintered body with a piezoelectric property, thus providing a piezoelectric ceramic device. This piezoelectric ceramic composition can be sintered together with an electrode consisting mainly of Ag at a low temperature. Even after the sintering, the composition has its insulation resistance not decrease and has its piezoelectric properties not decline.
