Abstract: The wafer test system includes: a prober including a chuck that holds a semiconductor wafer and a probe card having probe needles thereon, and brings the probe needles in contact with semiconductor chips formed on the semiconductor wafer to inspect the semiconductor chips; an overhead hoist transport that delivers the cassette that houses the plurality of semiconductor wafers to be inspected to the prober and withdraws, from the prober, the cassette that houses the semiconductor wafers that have been inspected; a conveying control unit that controls the overhead hoist transport to convey the probe card between a replacement position of the probe card predetermined in the prober and a storage of the probe card located in a place different from the prober; and a card conveying mechanism that conveys the probe card between a holding position in the prober and the replacement position.

Abstract: An antivibration unit attachment structure according to the present aspect includes: a vibration absorption part having a first elastic member which is elastically deformable in a first direction and which is connected to a vibration generation part; and a second elastic member which supports the vibration absorption part and which is connected to a vibration reception part. The second elastic member includes a movable part that extends from the vibration absorption part to both sides in a second direction and that is supported by the vibration reception part. The second elastic member is elastically deformable in the first direction and has an elastic coefficient different from that of the first elastic member. The vibration reception part includes a regulation member that comes into contact with at least one of the vibration absorption part and the second elastic member and that limits displacement of the second elastic member to the first direction.

Abstract: In a vehicle body front structure, a sub frame is fixed to front mount brackets and rear mount brackets of a pair of front side frames. A power unit is arranged on the front side of the sub frame in the vehicle body, and the power unit is supported by the pair of front side frames. A tilt surface is formed on the sub frame, and the tilt surface tilts to ascend toward the rear of the vehicle body. A rear portion of the power unit faces the tilt surface.

Abstract: An electrostatic recording apparatus includes a developing agent carrying member having a surface for carrying a developing agent thereon. A plurality of recording electrodes are arranged on the surface of the developing agent carrying member in parallel to each other at a predetermined gap while being electrically insulated from each other. An electrode cylinder is arranged to oppose the plurality of recording electrodes at a predetermined gap. A developing agent convey section conveys the developing agent such that a circulating convey path is formed along the surface of the developing agent carrying member. A voltage control section outputs a control signal including recording data. A recording electrode drive section is provided inside a space defined by the circulating convey path.

Abstract: An electrostatic recording apparatus includes a magnet roll for conveying a developing agent along a predetermined developing agent convey path. A plurality of recording electrodes are arranged to oppose the magnet roll and along the developing agent convey path. An opposite electrode has a portion opposing the plurality of recording electrodes and is arranged with a predetermined gap from the plurality of recording electrodes. A voltage applying unit applies a recording voltage corresponding to supplied dot recording information to each of the plurality of recording electrodes to generate a transferring electric field for transferring the developing agent to the opposite electrode between the opposite electrode and the plurality of recording electrodes, thereby forming a dot recording image corresponding to the dot recording information on the opposite electrode.

Abstract: An electrostatic recording apparatus includes a developing agent carrier member arranged along a predetermined developing agent convey path. A developing agent conveying section conveys a developing agent along a surface of the developing agent carrier member. A plurality of recording electrodes are arranged on the surface of the developing agent carrier member at a predetermined pitch. An opposite electrode is arranged to oppose the plurality of recording electrodes at a predetermined gap. A voltage applying section applies a voltage corresponding to recording information to each of the plurality of recording electrodes to selectively transfer the developing agent, which is conveyed along the surface of the developing agent carrier member, to the opposite electrode. The developing agent carrier member has a step at a portion on its surface shifted to an upstream side of a developing agent convey direction from a position closest to the opposite electrode.

Abstract: An internal combustion piston engine has a main combustion chamber supplied with a lean mixture and an auxiliary combustion chamber supplied with a rich mixture. A spark plug ignites a mixture in the auxiliary chamber to project a flame through a torch passage into the main chamber. Walls in the underside of the stationary head of the engine form a flame guide channel diverging from the torch passage toward intake and exhaust valves which are located equidistantly from the torch passage. The torch passage may comprise an elongated slot or a pair of spaced openings.

Abstract: Disclosed herein is a liner for an exhaust port system of an internal combustion engine for reducing heat loss from the exhaust gas to facilitate combustion of unburned hydrocarbons (HC) and oxidation of unburned carbon monoxide (CO). The exhaust port liner is rigidly secured at one end thereof to the exhaust port and is supported at its other end by means of a peripheral sealing ring to provide an airtight liner which is free sliding at said other end to accommodate expansion and contraction of the exhaust port liner by the exhaust gas passing therethrough.

Abstract: A residual gas control apparatus for internal combustion engines of the type including a main combustion chamber connected through a torch passage to an auxiliary combustion chamber having a spark plug, the residual gas control including a partial partition dividing the auxiliary combustion chamber into a first zone exposed to the spark plug and a second zone exposed to the torch passage, there being openings connecting the two zones, the partition and openings serving to control the percentages of residual gas in the two zones so as to produce optimum ignition and reduce NOx generation, and also to minimize turbulence in the vicinity of the spark plug.
