Patent number: 7345803Abstract: In an optical modulation device (10) having an electrical/optical interaction region (11), an electrical signal line (3) is connected to an electrical signal input terminal (2a), another electrical signal line (4a) is connected to an electrical signal output terminal (2b), and a reflection control circuit (5) is connected to the other electrical signal line (4a). This reflection control circuit (5) is an impedance element which positively reflects an output electrical signal from the interaction region (11) of the optical modulation device (10). This makes it possible to raise the upper-limiting frequency at which the E/O (Electrical-to-Optical) response characteristic can be improved, and improve the flatness of the frequency characteristic of the E/O response without deteriorating the absolute value of the E/O response.Type: GrantFiled: March 18, 2005Date of Patent: March 18, 2008Assignee: Nippon Telegraph and Telephone CorporationInventors: Hiroki Nakajima, Takayuki Yamanaka, Hideki Fukano, Yuichi Akage, Munehisa Tamura, Tadashi Saitoh

Patent number: 6935735Abstract: Images formed by a liquid are transferred onto both sides of a sheet-like recording medium without the liquid running on or penetrating into the recording medium. A layer of absorbing powder is formed on an intermediate transfer member. The liquid is applied to the powder layer formed on the intermediate transfer member so as to form a first visible image. The first visible image is transferred onto the front side of the recording medium. Thereafter, another layer of the absorbing powder is formed on the intermediate transfer member, and the liquid is applied to the powder layer so as to form a second visible image. The second visible image is transferred onto the back side of the recording medium.Type: GrantFiled: October 11, 2002Date of Patent: August 30, 2005Assignee: Ricoh Company, Ltd.Inventors: Kiyoshi Tanikawa, Aino Noguchi, Tadashi Saitoh
