Patent number: 9370885Abstract: A case molded article is molded by injecting resin into a molding space formed in an in-mold decoration die; meanwhile, foil is joined to the surface of the case molded article. After that, the foil is peeled off from the surface of the case molded article while leaving a pattern layer at least on the upper ends of the corners of the rising wall on the case molded article. Subsequently, the foil is peeled off from the surface of the case molded article while leaving the pattern layer at other points where the foil is joined to the surface of the case molded article.Type: GrantFiled: June 19, 2013Date of Patent: June 21, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kenji Nishitani, Masahumi Kurisu, Masamitsu Miyazaki, Akira Ezaki, Guangri Pei

Patent number: 4280034Abstract: A compact cash register comprises a first member for freely adjusting the visual angle of the same. The first member is connected to a second member of a casing of the compact cash register so as to provide in order to adjust the visual angle of the cash register. The first member comprises a ball biased continuously by a spring. The second member includes a cavity formed on the surface of a cover of the casing. The connection between the first member and the second member allows the compact cash register to be supported obliquely. The connection may be formed as a ratchet mechanism, a pivotal mechanism and the like. The casing comprises at least two compartments each containing the compact cash register and cash, the two compartments being adjacent to each other.Type: GrantFiled: February 28, 1979Date of Patent: July 21, 1981Assignee: Sharp Kabushiki KaishaInventors: Akira Ezaki, Yoshiaki Kobayashi, Sigeaki Hayashi
