摘要： The invention has an object for improving response of a fuel injection device. A flow-in recessed portion and a flow-out recessed portion are formed at a press-contacting surface of a floating plate, which is movably accommodated in a pressure control chamber. A flow-in port and a flow-out port are formed at a pressure control surface of a valve body. The flow-in port is opened to the flow-in recessed portion, while the flow-out port is opened to the flow-out recessed portion. When the floating plate is moved upwardly and the press-contacting surface is brought into contact with the pressure control surface, the flow-in port is surely closed.

摘要： In an acoustic design support apparatus, a speaker selection supporter selects a desired speaker as a candidate for use in a given space based on shape information representing a shape of the space. A speaker mounting angle optimizer calculates an optimal mounting direction of the selected speaker by selecting a mounting direction pattern which minimizes a degree of variation among sound pressure levels at a plurality of positions on a sound receiving surface defined in the space. An acoustic parameter calculator calculates a variety of acoustic parameters at sound receiving points within the space based on both of the shape information of the space and the optimal mounting direction of the speaker.

摘要： A sender produces a background video image 4 from a reference video image 1 and a depth map 3 and synthesizes the background video image 4 in a background buffer 5. A projection converting matrix 6 for synthesizing is calculated. A receiver receives the reference video image 1, the depth map 3 and the projection converting matrix 6. The receiver produces a free viewpoint video image 11 and a background video image 12. The background buffer 13 is dynamically renewed. The free viewpoint video image 11 and the image in the background buffer 13 are synthesized with each other, and the background video image in the concealed regions in the free viewpoint video image are complemented to obtain the complemented image 14.

摘要： A voice recognition system includes an adaptive filter and a subtractor. The adaptive filter generates a simulated talk-back voice y(n) by setting a filter coefficient simulating a transfer system in which an input voice corresponding to a voice command and a talk-back voice output from a speaker are input into a microphone and by filtering a talk-back voice x(n). The subtractor extracts the input voice by subtracting the simulated talk-back voice y(n) from mixed sound input into the microphone. With this configuration, the talk-back voice is attenuated from the mixed sound including the input voice and the talk-back voice input tedinto the microphone, and then, the mixed sound is supplied to a voice recognition engine. Accordingly, the user can input his/her voice during a talk-back operation without the need to interrupt it by pressing a speech button every time the user wishes to input the voice. The voice recognition operation time can be thus reduced.

摘要： When a vehicle is traveling along a route toward a parking lot located near a destination facility, if traffic congestion along the route is detected, the navigation apparatus searches for an alternative parking lot that allows a user to reach the destination facility earlier than can by using the original parking lot. If such an alternative parking lot is detected, the predicted driving time and the predicted walking time are displayed together with a route to the parking lot. When traffic congestion is encountered when transporting a passenger by vehicle, the navigation apparatus determines a quicker way for the passenger to reach the destination facility. If the navigation apparatus detects that the passenger can reach the destination facility earlier if the passenger disembarks the vehicle and walks to the destination facility, the navigation apparatus presents information indicating a best point at which the passenger should disembark the vehicle.

摘要： A common rail injector for injecting fuel through a high-pressure channel includes a control chamber, a control valve, and a drive unit. The control chamber applies pressure to a nozzle needle. The control valve switches communication of the control chamber between the high-pressure channel and a low-pressure channel. The drive unit selectively sets a valve element of the control valve on a low-pressure side seat or a high-pressure side seat. The drive unit has an actuator and a slide pin member. The slide pin member slides inside a slide hole to transmit a force to the valve element. A diameter of the low-pressure side seat is less than or equal to a diameter of the high-pressure side seat. The pressure in the control chamber is exerted as an assistance force, so that a high-pressure side seat closing load becomes less than or equal to a low-pressure side seat opening load.

摘要： A first characteristic value extracting unit extracts a characteristic value from a picture transmitted from a transmission side, and a second characteristic value extracting unit extracts a characteristic value from a picture received on a reception side. These extracted characteristic values are supplied to a central monitoring unit through low speed lines, respectively. In the central monitoring unit, an MSE (mean square error) is assessed from the data by an MSE assessing unit. The first and second characteristic value extracting units divide an input picture into blocks, subject the blocks to an orthogonal transformation, or subject the blocks to PN sequence multiplication before the orthogonal transformation, and extract and output orthogonal transformation coefficients. The MSE assessing unit determines the differences between corresponding coefficients on the transmission side and the reception side and squares the differences, adds the squared differences for every coefficients or every blocks, and assess an MSE based on the added values referred to a table. With this operation, the MSE can be effectively assessed using a smaller amount of extracted data (accordingly, slower speed lines can be used in the central monitoring unit).

摘要： A nozzle needle of a fuel injector is driven in a controlled manner by changing back pressure applied thereto. The back pressure is controlled by a pressure control valve driven by stacked piezoelectric elements. A valve body of the pressure control valve is disposed in a valve chamber having a drain port and a high pressure port which are selectively closed. A diameter D1 of a drain seat, a diameter D2 of a high pressure seat, and a diameter D3 of a piston portion connected to the valve body are set to satisfy a relation: D1≧D2≧D3. In this manner, operation of the pressure control valve is stabilized, and thereby the fuel injector is smoothly and stably operated.
