  • Patent number: 7345803
    Abstract: 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.

  • Patent number: 6935735
    Abstract: 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.

  • Patent number: 6920166
    Abstract: A masking material 13, which includes stripe-like openings 12 parallel to the [1-100] direction of a nitride semiconductor thin film, is formed on a substrate. Nitride semiconductor thin films 11 doped with Mg are grown on the openings 12 by selective-area growth. The nitride semiconductor thin films 11 are composed of a portion 14 formed as a result of the growth in the direction perpendicular to a (0001) principal plane, and a portion 15 formed as a result of the growth of {11-2x} facets (x=0, 1, 2). The Mg concentration of the portion 15 is made lower than that of the portion 14.

  • Publication number: 20050139477
    Abstract: To avoid change in plating performance, even where operation of the plating equipment is interrupted, the properties of the plating solution need to be preserved. For plating equipment having an insoluble anode, add a reservoir (7) for storing a replacement solution to the tank (4) having a metal ion supply source (copper ball (5)) and, upon termination of the plating operation, the entire plating solution is discharged from the tank (4) containing the metal ion supply source, while the solution for replacement is transferred from the reservoir (7) to the empty tank having a metal ion supply source, and immediately prior to the resumption of the plating operation transfer the solution for replacement back to the reservoir (7) and return the plating solution to the tank (4) containing the metal ion supply source.

  • Patent number: 6373892
    Abstract: A method for compressing and decompressing moving picture information wherein a key signal is correctly reproduced and coding is efficiently carried out, and a video signal processing system for implementing the method. At the time of coding a video signal, conversion is carried out for make large a distance between an ordinary digitized video signal and a key signal indicative of whether an image indicates background or foreground for data compression. At the time of decoding the coded video signal, the video signal and key signal of the decompressed image are separated based on a predetermined threshold and reverse conversion opposite to the coding mode is carried out. Since the coding is carried out with the ordinary video signal separated from the key signal, the video signal and the key signal can be separated by a suitable threshold from the compressed and then decompressed image and thus the video signal and key signal can be correctly reproduced.
