A vehicle existence annunciator device drives a speaker by utilizing an electric power, which is supplied from an electric power source, to emit an annunciation sound to the outside of a vehicle. The vehicle existence annunciator device includes a counter-voltage-reduction unit configured to enhance a sound pressure level at a frequency, which is apt to linger in a human's ear, when a power supply voltage applied from the electric power source to the vehicle existence annunciator device decreases.

The invention provides a metalworking oil composition which is used for a very small amount of oil-feeding type metalworking method, said composition comprising a base oil selected from the group consisting of natural fats and oils, derivatives thereof and synthetic ester oils; and an antirust agent comprising a sorbitan fatty acid ester and a phospholipid, and a metalworking method using the composition and metalwork obtained by the metalworking method. The oil composition shows excellent lubricity and antirust property and is suitably used for metalworking of metallic materials such as cast iron, steel, stainless steel, and nonferrous metal (such as Al alloy and Mg alloy) by a method in which a very small amount of oil is supplied.

The present invention can reliably adjust the lip-sync between an video and audio at a decoder side, without making the viewer feel strangeness.In this invention, the encoded video frames to which video time-stamps VTS are attached and the encoded audio frames to which audio time-stamps ATS are attached, all received, are decoded, generating a plurality of video frames VF1 and a plurality of audio frames AF1. The video frames VF1 and audio frames AF1 are accumulated. Renderers 37 and 77 calculate the time difference resulting from a gap between the reference clock for the encoder side and the system time clock stc for the decoder side. In accordance with the time difference, the timing of outputting the plurality of video frames, one by one, on the basis of a timing of outputting the plurality of audio frames, one by one. Hence, the lip-sync can be achieved, while maintaining the continuity of the audio.

A steam turbine plant partially utilizes a hydrocarbon fuel such as an LNG as a fuel to improve the efficiency of the plant. A steam turbine plant includes a boiler, a steam turbine, a feedwater system, and a superheating combustor. The boiler generates steam, and the steam turbine is driven by the steam generated in the boiler. The feedwater system recovers the steam exhausted from the steam turbine and supplies the steam to the boiler as a feedwater. The superheating combustor is provided between the boiler and the steam turbine, wherein fuel originated from hydrocarbon fuel and oxidizer are mixed with the steam generated in the boiler and combusted in the superheating combustor to increase the temperature of the steam.

A touch panel 47 is constructed by a display/sensor unit 51a which is slightly larger than a display screen of an LCD 46 and a sensor unit 51b which is projected to the outside from one side, for example, from one side on the right. A finger 52 of the user is touched to a selection item such as desired button, icon, or the like on the display/sensor unit 51a and vertically moved on the sensor unit 51b. A selection display 53 constructed by a plurality of buttons is displayed along the side of the right side of the display screen by the LCD 46. A button beside the finger 52 is highlighted and when the finger 52 is released, the highlighted button is selected. If there are no buttons adjacent to the finger 52, the button is not highlighted. Even if the finger 52 is released, the state is not changed. When finger 52 is moved to the display/sensor unit 51a, the selection display 53 disappears.
摘要:
A method and apparatus for creating user configurable interactive display, wherein a control area is invoked in order to display representations of at least one operating environment. The operating environment contains user interactive components corresponding to information resources which may be selected for use by the user. A scratch pad is invoked onto the display allowing a user to select components from the operating environment to be placed onto the scratch pad. Once the interactive components from one or more operating environments are placed onto the scratch pad, a user interactive display area is generated comprising a display of user selected components.
