Patent number: 10367170Abstract: A first electrode having light transmissivity is formed on a first surface of a first light transmissive substrate and. An organic functional layer includes a light-emitting layer and is located on an opposite side to the first light transmissive substrate with the first electrode interposed therebetween. A second electrode is located on an opposite side to the first electrode with the organic functional layer interposed therebetween. A second surface which is a surface of the first light transmissive substrate on an opposite side to the above-mentioned first surface is fixed to the second light transmissive substrate, which has a bending rigidity higher than that of the first light transmissive substrate. First irregularities are present in the second surface of the first light transmissive substrate, and second irregularities are positioned in a surface of the second light transmissive substrate which faces the first light transmissive substrate.Type: GrantFiled: July 27, 2017Date of Patent: July 30, 2019Assignee: PIONEER CORPORATIONInventor: Yasunobu Higashika

Publication number: 20130337216Abstract: In an optical disc including a discoid optical-disc substrate and a coating film formed on the optical-disc substrate, the optical-disc substrate includes a first region including the innermost periphery thereof and having a projection formed on the whole of the first region, and a second region located outside of the first region. The coating layer is formed on the second region. Before the coating film is formed, the thickness of the optical-disc substrate at the first region is greater than the thickness of the optical-disc substrate at the second region. After the coating film is formed, the total thickness of the optical-disc substrate at the second region and the coating film is greater than the thickness of the optical-disc substrate at the first region.Type: ApplicationFiled: January 27, 2011Publication date: December 19, 2013Applicant: Pioneer CorporationInventors: Yasunobu Higashika, Takao Tagiri

Patent number: 6464485Abstract: An ultrasonic injection mold for an optical disk includes a movable die and a fixed die; a disk molding cavity formed between the movable die and the fixed die; a stamper positioned at the bottom of the cavity for forming a pit on a surface of the disk; and an ultrasonic generation device provided on the movable die or fixed die for applying ultrasonic waves to the cavity in performing infection molding. One or more slits are formed on the movable die and the fixed die in the direction which crosses the radial direction of the cavity. The ultrasonic injection mold minimizes the amplitude of the ultrasonic transmitted in the radial direction of the cavity.Type: GrantFiled: June 23, 2000Date of Patent: October 15, 2002Assignees: Pioneer Corporation, Pioneer Video Corporation, Idemitsu Petrochemical Co., Ltd.Inventors: Tetsuya Iida, Noriyoshi Shida, Keiji Suga, Kenichi Ishiguro, Yasunobu Higashika, Atsushi Sato, Kunitoshi Katagiri
