Patent number: 8933785Abstract: There is provided a power conversion system, and a photovoltaic inverter includes a communication unit that broadcast-transmits a setting request signal of a predetermined communication address. The photovoltaic inverter includes a display unit that displays the predetermined communication address indicated by the setting request signal, and an address setting unit that generates a setting completion signal indicating that the predetermined communication address has been set as the communication address of the photovoltaic inverter if an input accepting unit accepts an input such that the predetermined communication address is set. An address management unit of the photovoltaic inverter generates a setting request signal indicating a communication address other than the predetermined communication address if the setting completion signal for the predetermined communication address is received.Type: GrantFiled: June 24, 2009Date of Patent: January 13, 2015Assignee: Mitsubishi Electric CorporationInventors: Yoshinori Inukai, Noboru Andou, Isao Shikata, Naoki Nishio

Patent number: 7444052Abstract: A display device includes an illuminating device having an optical waveguide plate for introducing light thereinto, a drive assembly having a planar array of actuators disposed in facing relation to the optical waveguide plate, a displacement transmitter assembly disposed between the optical waveguide plate and the drive assembly, and a light scattering layer disposed on the displacement transmitter assembly. The actuators are selectively displaceable to bring the light scattering layer into and out of contact with the optical waveguide plate, for controlling light that leaks from the optical waveguide plate as emitted light. The display device also includes an optical modulator for modulating the emitted light from the illuminating device to display an image. The illuminating device has a light reflecting layer disposed on at least a portion of the displacement transmitter assembly that confronts the optical waveguide plate.Type: GrantFiled: March 17, 2005Date of Patent: October 28, 2008Assignees: NGK Insulators, Ltd., Sharp Kabushiki KaishaInventors: Kenichi Iwauchi, Kei Tokui, Yukihisa Takeuchi, Tsutomu Nanataki, Natsumi Shimogawa, Isao Shikata

Publication number: 20060214557Abstract: A light source has a transparent substrate, a fixed substrate disposed in facing relation to the transparent substrate, and a plurality of electron emitters disposed on a principal surface of the fixed substrate. A light reflecting film is disposed on a portion of the principal surface of the fixed substrate which is free of the electron emitters. An anode electrode in the form of a transparent electrode is disposed on a substantially entire reverse side of the transparent substrate. Phosphor layers are disposed on the anode electrode at respective positions facing the electron emitters.Type: ApplicationFiled: March 16, 2006Publication date: September 28, 2006Applicant: NGK Insulators, Ltd.Inventors: Iwao Ohwada, Natsumi Shimogawa, Tetsuyuki Kameji, Naoki Goto, Isao Shikata

Publication number: 20060214556Abstract: A light source has a transparent substrate, a fixed substrate disposed in facing relation to the transparent substrate, at least one electron emitter disposed on the fixed substrate, a phosphor layer disposed on a surface of the transparent substrate which confronts the fixed substrate, and a trajectory deflector for deflecting the trajectory of a pulsed electron flow intermittently emitted from the electron emitter. The pulsed electron flow is deflected by the trajectory deflector to two-dimensionally scan a position of the phosphor layer which is irradiated with the pulsed electron flow for thereby spreading the pulsed electron flow.Type: ApplicationFiled: March 20, 2006Publication date: September 28, 2006Applicant: NGK Insulators, Ltd.Inventors: Iwao Ohwada, Natsumi Shimogawa, Tetsuyuki Kameji, Naoki Goto, Isao Shikata

Publication number: 20030043091Abstract: A display system includes a light guide plate for transmitting light therethrough, and a panel portion arranged opposite to a back of said light guide plate. The panel portion includes a driving portion provided with actuators of the number corresponding to that of a number of pixels. The panel portion causes a video image to be displayed on the light guide plate according to an inputted image signal, by introducing light into the light guide plate and controlling displacement operations in contact and separation directions of the actuators with respect to the light guide plate according to properties of the image signal, and thereby controlling leakage light in a predetermined region of the light guide plate. The display system further includes a cooling device for controlling flow of a fluid in contact with the back of the light guide plate, to cool the light guide plate from its backside.Type: ApplicationFiled: September 4, 2002Publication date: March 6, 2003Applicant: NGK Insulators, Ltd.Inventors: Yukihisa Takeuchi, Tsutomu Nanataki, Iwao Ohwada, Isao Shikata, Kei Sato
