  • Publication number: 20170008063
    Abstract: Provided is a polygonal in which a decoration effect equivalent to that of a cylindrical base-can is obtained without causing folding or deformation in a can body-part. Bottom-part outer-peripheral parts (A-2) of a cylindrical base-can that are expected to form linear parts (B-2) of a polygonal can (B) are moved inward in a radial direction, while bottom-part outer-peripheral parts (A-1) of the cylindrical base-can that are expected to form corner parts (B-1) of the polygonal can are moved outward in the radial direction. Thus, the polygonal can is molded such that the body-part cross-section peripheral length of the cylindrical base-can and the body-part cross-section peripheral length of the molded polygonal can have a substantially isometric relationship.

  • Publication number: 20160240365
    Abstract: In a light-emitting sealed body, a metal structure (electron emission structure) containing an easily electron-emitting material is used, so that it is not necessary to perform feeding for discharge between electrodes. Therefore, a feeding member does not need to be connected to the metal structure from the outside of a bulb. In addition, in the light-emitting sealed body, the metal structure is disposed in an internal space S of the bulb and a positioning unit of the metal structure is disposed only in the bulb. Therefore, in the light-emitting sealed body, the metal structure and the positioning unit do not penetrate the bulb and are not buried in the bulb and weakened portions are not formed in the bulb made of glass. Therefore, a sealing state of the bulb can be maintained surely.

  • Patent number: 9223159
    Abstract: A spatial light modulation device includes a phase-modulation type spatial light modulator, a temperature sensor detecting a temperature of the spatial light modulator, and a control unit providing a drive signal to the spatial light modulator. The control unit has a storage unit. The storage unit stores N correction patterns created so as to correspond to N (N is an integer not less than 2) temperature values of the spatial light modulator in order to correct phase distortion of the spatial light modulator. The control unit selects one correction pattern according to a temperature value of the spatial light modulator, and generates the drive signal based on a phase pattern created by adding the one correction pattern to a desired phase pattern. Thereby, it becomes possible to suppress phase distortion according to a temperature change while suppressing a delay in operation.
