  • Patent number: 12065805
    Abstract: A work machine includes a second pilot line that introduces a hydraulic fluid from a pilot hydraulic fluid source to a pilot valve bypassing a first gate lock valve, a second gate lock valve that is disposed on the second pilot line and that is configured to be switched to an open position for allowing the supply of the hydraulic fluid to the pilot valve or a closed position for interrupting the supply of the hydraulic fluid, and a controller that controls the second gate lock valve on the basis of a second remote operation signal transmitted from a remote operation apparatus and that controls the pilot valve according to a first remote operation signal transmitted from the remote operation apparatus. In a state where the first gate lock valve is at a closed position, the second gate lock valve is allowed to be controlled by the controller when stairs are in a retracted state, and is kept at the closed position irrespective of the second remote operation signal when the stairs are in an extended state.

  • Patent number: 7386266
    Abstract: An image removing method including bringing an outermost layer of a removing member into contact with an image fixed on an image support without applying a liquid to the image while heating the image and the outermost layer; and separating the removing member from the image support to remove the image from the image support, wherein the removing member includes a substrate and the outermost layer which is located overlying the substrate and which includes a thermoplastic resin, and wherein the image includes a removing agent which can decrease adhesion force of the image to the image support when heated.

  • 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.
