Patent number: 8470403Abstract: An organic thin film deposition device that is compact and high in processing capability is provided. Inside a vacuum chamber, first and second substrate arrangement devices that can be in a horizontal posture and a standing posture are provided; and when in the standing posture, substrates held by the respective substrate arrangement devices and first and second organic vapor discharging devices face each other. When one of the substrate arrangement devices is in the horizontal posture, masks and the substrates are lifted up by alignment pins and transfer pins and are replaced with a substrate not yet film formed, for position adjustment. With one organic thin film deposition device, two substrates can be processed at the same time.Type: GrantFiled: May 18, 2012Date of Patent: June 25, 2013Assignee: Ulvac, Inc.Inventors: Masato Fukao, Hiroshi Kikuchi, Yoshio Sunaga

Patent number: 8224228Abstract: A cover closer having a drive unit for electrically opening and closing a cover of a copying machine or the like is described. The cover closer can ease the burden of manipulation of the cover and minimize the constraints on designing the main body of the copying machine and the like. The cover closer is provided with a compact drive unit having a high reduction ratio by the use of planetary gears which reduce the input torque necessary for opening and closing the cover, so as to downsize an electric motor used in the drive unit. The drive unit can therefore be installed within the hinge structure of the cover closer.Type: GrantFiled: October 20, 2008Date of Patent: July 17, 2012Assignee: Simotec Inc.Inventors: Kazuo Saitou, Yoshio Sunaga

Patent number: 8205952Abstract: A technology for placing spacers free from the occurrence of streaks is provided. Random numbers are generated by a computer, and made in one-by-one association with discharge positions of an object for discharging every generation, and stored in a memory unit of the computer. Coefficient values are determined for the respective discharge positions based on the stored random numbers, and individual voltage values to be required for the respective discharge positions are calculated through the multiplication of voltages set for respective nozzle holes N1 to Nn by the coefficient values. When the respective voltages corresponding to the discharge positions are applied to piezoelectric elements inside a discharge head and a discharge liquid containing the spacers are discharged through the plural nozzles N1 to Nn provided in the discharge head, the spacers are placed on the object for discharging by numbers according to the random numbers.Type: GrantFiled: October 8, 2009Date of Patent: June 26, 2012Assignee: Ulvac, Inc.Inventors: Takumi Namekawa, Kouji Hane, Masasuke Matsudai, Yoshio Sunaga, Junpei Yuyama, Hidenori Suwa

Patent number: 6533630Abstract: A vacuum display device for enabling the manufacture of high quality plasma display device with high throughput. A front panel 6 constituting a plasma display device is carried into a film deposition chamber 22; and a MgO thin film is deposited in a vacuum atmosphere. The front panel 6 is then carried into an alignment chamber 11 without being exposed to the atmosphere and aligned with a rear panel 7 that has been subjected to degassing in a vacuum atmosphere. There is no absorption of gas, such as moisture; and the quality of the thin film is not degraded. After alignment, aging processing is carried out without exposure to the atmosphere, followed by gas encapsulation and hermetic sealing, which further increases throughput.Type: GrantFiled: May 26, 2000Date of Patent: March 18, 2003Assignee: Nihon Shinku Gijutsu Kabushiki KaishaInventors: Ryuuichi Terajima, Yukio Masuda, Toshiharu Kurauchi, Ken Momono, Yoshio Sunaga, Hidenori Suwa, Kyuzo Nakamura
