Abstract: A fuel injector inhibiting adhesion of deposits and simultaneously improving durability by a simple configuration is provided. A fuel injector having a valve body provided with a main space receiving fuel and an injection hole and a needle movably supported at the valve body and having a seal part at its front end, in which needle the movement causes the seal part to separate from or contact an inner surface of the valve body and thereby open or close a fuel passage communicating the main space and the injection hole of the valve body, the fuel injector characterized in that the injection hole of the valve body is covered by an injection hole coating comprised of a material with a lower adsorption and reactivity with oxygen compared with the material of the valve body itself, and the seal part of the needle is covered by a seal part coating comprised of a material higher in liquid-repellency compared with the material of the needle itself and not forming a metal surface.

Abstract: In a fuel injection nozzle for an internal combustion engine, a first cavity is disposed downstream of a valve seat in a direction in which fuel flows. A second cavity is disposed downstream of the first cavity in the direction in which the fuel flows. A fuel passage connects the first cavity to the second cavity. Fuel injection holes (24) lead to the second cavity. With this configuration, when the fuel flows through the first fuel passage, cavitation is induced. Cavitation bubbles flow into the second cavity along with the fuel. When the fuel is retained in the second cavity, the cavitation bubbles are uniformly mixed into the fuel. The fuel, which has been sufficiently mixed with the cavitation bubbles, is injected from the fuel injection holes.

Abstract: The present invention provides a plasma injector wherein a reducing agent injected from an injection port (19) at the distal end portion of an injection nozzle (18) is at least partially converted into a plasma; an exhaust gas purifying system; and a method for injecting a reducing agent. Using the plasma injector, the exhaust gas purifying system, and the method for injecting a reducing gas of the present invention, it is possible to vaporize a reducing agent supplied in an injection manner and/or to provide a highly reactive reducing agent from the reducing agent.

Abstract: The present invention provides a device and a method for supplying a fuel or a reducing agent, where a fuel or reducing agent supplied by injection can be vaporized and/or a fuel or reducing agent having high reactivity can be provided, and provides a plasma torch (30) usable therefor. The device for supplying a fuel or a reducing agent comprises a plasma torch (30) for converting a gas (23, 33) into a plasma and blowing out the plasma, and an injector (18) for injecting a fuel or a reducing agent to a region (20) where the plasma is supplied. The method comprises converting a gas (23, 33) into a plasma, blowing out the plasma, and injecting a fuel or a reducing agent to the plasma region (20).

Abstract: A needle valve 20 having a seat contact section 24 at a leading end is provided. A nozzle body 22 having a seat section 26 with which the seat contact section 24 comes into contact is provided. The nozzle body 22 comprises a tapered surface 34, which includes the seat section 26, and a fuel receiver section 28, which includes a spherically shaped sack wall surface 36. The leading end of the needle valve 20 comprises a first protrusion 38, which is tapered to have a greater taper angle than the tapered surface 34, and a second protrusion 40, which is tapered to have a smaller taper angle than the first protrusion 38. More specifically, the second protrusion 40 is conically shaped.

Abstract: A file management apparatus includes the following elements: a representative image storage device storing representative image data of each of a plurality of content files in association with a creation time of the content file; a rendering unit rendering the representative image data at a position corresponding to the creation time with a calendar continuous over days, months, and years serving as a background; a display state maintaining unit maintaining, as a display state, a time-axis range of the calendar being displayed and a position thereof; an operation receiving unit receiving a change operation to change the display state, the change operation commonly being a scrolling operation in a time-series direction in any time-axis range; and a controller controlling, in response to the change operation, the rendering means to render the representative image data on the calendar on the basis of the display state.

Abstract: In a fuel supply apparatus for an internal combustion engine including a first fuel injection valve for directly injecting a fuel into a cylinder and a second fuel injection valve for injecting the fuel into an intake manifold, production of deposits in the first fuel injection valve is prevented and a satisfactory homogenous air-fuel mixture can be formed during homogenous combustion while an engine is at idle. In order to achieve this effect, during homogenous combustion while the engine is idle, a second fuel injection valve injects the fuel and a first fuel injection valve injects the fuel to which pressure has been applied by a low-pressure pump, without a high-pressure pump applying further pressure to the fuel.

Abstract: An image reproduction system configured by an image reproduction device that can accumulate a still image or a moving image for reproduction, and an information processing device that makes a setting to the image reproduction device.

Abstract: A true activity of tissue plasminogen activator is determined by reacting a solid phase having bound thereto anti tissue plasminogen activator antibody IgG fraction having affinity to a site other than the active site of tissue plasminogen activator with tissue plasminogen activator in a sample and then measuring an activity of the reaction product, preferably in terms of an amount of a substance released from a chromogenic peptide substrate. This measurement enables to use of whole blood or diluted blood as the sample and achieves high sensitivity and high accuracy in a short period of time.
