摘要:
A fuel injection valve has a flat injection hole plate arranged downstream of a valve seat on which a valve body is seated. A plurality of injection holes are formed through the injection hole plate in such a manner that the injection holes are inclined with respect to the axis of the valve body, to thereby increase the distance from the axis of the valve body in the downstream direction. The diameter of the injection hole is from 0.17 to 0.35 mm, and the chamfer dimension R at the inlet of the injection hole on the inlet side of the injection hole plate at the side close to the axis of the valve body, is greater than or equal to 0.1 mm. Accordingly, the flow reistance on the fuel flowing into the injection hole can be reduced, to thus prevent a vaporization of fuel due to a vacuum evaporation. With such a construction, even when the fuel injection valve is disposed in a vacuum box maintained in a vacuum atmosphere and an inspection for vacuum characteristics performed by injecting fuel, a variation of the flow rate can be maintained with good characteristics under a small flow rate variation rate and therefore, the production yield of the fuel injection valve can be improved.

A total of n signal processing circuits respectively constituted by independent circuit blocks process signals at the Data Link and Physical Layers. The signal processing circuits are associated with respective n groups of M/n subcarriers each, to process signals at the Data Link and Physical Layers. For example, the signal processing circuit independently processes signals of the subcarrier group at the Data Link and Physical Layers, the signal processing circuit independently processes signals of the subcarrier group at the Data Link and Physical Layers, and so on. The signal processing circuit independently processes signals of the subcarrier group at the Data Link and Physical Layers.

A stop method for a fuel cell system including a fuel cell unit in which hydrogen is supplied to an anode, and air is supplied to a cathode so as to generate electrical power via an electrochemical reaction. The stop method includes the steps of stopping supply of hydrogen to the anode, electrically connecting the anode and the cathode via an electrical load, and supplying air to the anode.

A driving support apparatus includes an imaging member taking an image corresponding to a vehicle peripheral area; a steering angle detecting member detecting a steering-wheel steering angle; a display member disposed in a vehicle interior to display the image; and a control member predicting a driving course of the vehicle according to the detected steering-wheel angle. The control member synthesizes a predicted driving course image relating to the predicted driving course. The control member superposes the predicted driving course image at a corresponding position of the image. The control member displays on the display member the image where at least one image, on which an index is marked at least at one height position, is superposed at least on the predicted driving course image and onto a side of the predicted driving course image while the control member displays the superposed image on the display member.
摘要:
A graphite crucible for silicon single crystal manufacturing by the Czochralski method, having a long life cycle, contains at least one gas venting hole provided in a corner portion of the crucible. Gas generated by reaction between the graphite crucible and a quartz crucible is released to the outside through the gas venting hole, and formation of SiC on the surface of the graphite crucible and deformation of the quartz crucible caused by the pressure of the generated gas are prevented.

A fuel cell system includes a fuel cell, an oxidant gas passage, a cathode off-gas passage, a fuel gas passage, a circulation passage, an anode off-gas passage, a fuel shutoff valve, a supply device, a humidifier and a control device. The supply device supplies a scavenging gas, which is for scavenging the fuel cell, to the anode and the cathode. The humidifier humidifies the scavenging gas. The control device controls the supply device when the fuel cell is turned off so that supply of the fuel gas to the anode is shut off and the scavenging gas is supplied to the anode and the cathode, wherein supply of the scavenging gas to the cathode is conducted through the humidifier.
摘要:
A frame, which is the data unit, is extracted without decoding MPEG audio data. Then, a scale factor included in the frame is extracted and an evaluation function is calculated based on the scale factor. If the value of the evaluation function is larger than a prescribed threshold value, the speed of the frame is converted. If the value of the evaluation function is smaller than the prescribed threshold value, the frame is judged to be a frame in a silent section and neglected. The speed conversion is made by thinning out frames or repeating the same frame as many times as required according to prescribed rules.
摘要:
A fuel cell which can self-heat in a short time, in which no reaction gas is necessary for combustion, thereby improving the starting performance at low temperatures. The fuel cell comprises a cell structure in which an anode and a cathode are provided on either side of a solid polymer electrolyte membrane. This cell structure has a power generation plane and at least a part of the generation plane is defined as a local generation area so as to locally generate power. The fuel cell may include a pair of separators between which the cell structure is placed, and a reaction gas passage may be formed between the cell structure and each separator. One of a system for supplying a reaction gas to only a part of the reaction gas passage, and a system for supplying a reaction gas to the entire reaction gas passage is switchably selected.

A fuel injection valve has: a tubular body, a valve seat member, a valve body, a core tube, a bias spring, and an electromagnetic actuator. The core tube is press fitted into the tubular body. The core tube has a first end side opposing an absorption section of the valve body in such a manner as to form an axial gap interposed between the first end side of the core tube and the absorption section. The core tube has a second end side axially extending in the tubular body to a certain position on a way to the second end side of the tubular body. The axially extending second end side of the core tube has an outer periphery which is formed with a reduced diameter section for increasing an accuracy in positioning the core tube when the core tube is press fitted into the tubular body.

A portable terminal device includes: a first member having a keyboard operation portion; and a second member having a display portion and attached to the first member via a coupling member movable in a horizontal direction relative to the first member, the second member being movable together with the coupling member in the horizontal direction relative to the first member. The second member is rotatably attached to the coupling member so that a side face or a rear face of the second member is allowed to face forward after the coupling member is moved in the horizontal direction relative to the first member. It is also possible to attach the coupling member to the first member so as to be slidable in one direction or rotatable in the horizontal direction, and to attach the second member to the coupling member to be rotatable in the horizontal direction.
