Patent number: 8877030Abstract: A magnetic film plating apparatus employs a dip method that allows relatively good escape of bubbles and does not require a wide footprint and, even when a ferromagnetic material is used for an anode, can form a magnetic film on a substrate surface while minimizing the influence of the anode on the uniformity of magnetic anisotropy in the magnetic film. The magnetic film plating apparatus includes a plating tank for holding a plating solution, an anode vertically disposed in the plating tank at a position to be immersed in the plating solution, a substrate holder for holding a substrate W and positioning the substrate W opposite the anode, and a magnetic field generator, disposed outside the plating tank, for generating a magnetic field around the substrate W held by the substrate holder and positioned opposite the anode.Type: GrantFiled: July 7, 2009Date of Patent: November 4, 2014Assignee: Ebara CorporationInventors: Yasuhiko Endo, Fumio Kuriyama, Masaaki Kimura

Patent number: 8623503Abstract: Disclosed is a chromium-free rust-inhibitive surface treatment agent to form a siliceous film that rarely cracks or peels off and yields an excellent rust-inhibitive performance on zinc surfaces of a metal part. The chromium-free rust-inhibitive surface treatment agent is an alcoholic solution of alkoxysilane oligomer having weight-averaged molecular weight of 1,000 to 10,000, and 2.5 to 15% of silicon in molecules of the alkoxysilane oligomer has been replaced with titanium.

Patent number: 7352486Abstract: The printer includes a CPU, a bridge image processing unit, a RAM, a ROM, a supply power control unit, a printing unit, a communication I/F, and physical layer I/Fs. When the Ethernet is connected to the communication I/F, if the DMA transfer request signal is not outputted from the DMAC for more than a specific time, the supply power control unit shifts into the sleep mode that halts the supplies of clock to the CPU, etc.; and if data is received from the host computer group, the supply power control unit releases the sleep mode. Further, in case that equipment conforming to the USB standard or the IEEE 1284 is connected to the communication I/F, if the DMA transfer request signal is not outputted from the DMAC for more than the specific time, the supply power control unit shifts into the power halt mode that halts the supply of power to the CPU, etc. Thus, the invention provides a printer capable of effectively reducing the power consumption.Type: GrantFiled: April 18, 2006Date of Patent: April 1, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Noriaki Tsuchiya, Yasuhiko Endo, Masahiko Kikuchi
