    摘要: In a variable valve opening property internal combustion engine, a control shaft (20) is supported by a control link (21) which is in turn is pivotally supported by a cylinder head (1), and a roller link (22) is pivotally supported by the control shaft. The roller link is provided with a cam roller (31) that engages a cam (3) of a camshaft (4) and a roller shaft (32) that engages a slipper surface (33) of a rocker arm (6). The arcuate movement of the cam roller centered around the control shaft varies the swing of the rocker arm and hence the valve lift in dependence on the position of the control shaft. A compression coil spring (41) is interposed between a part of the cylinder head and a side of the cam roller facing away from the cam. The coil spring is oriented such that a direction of a spring force (Fspg) substantially coincides with a direction of a guided movement of the cam roller, preferably in a low valve lift condition.

    摘要: A machine tool assembly having a base assembly movable relative to a support selectively a) oppositely parallel to a first line, and b) oppositely parallel to a second line that is orthogonal to the first line, and a first spindle headstock movable with the base assembly and having a central axis extending parallel to the first line and a working end. The machine tool assembly further includes a first turret assembly movable with the base assembly and having a first turret headstock and a first turret head that is movable around a first axis relative to the first turret headstock. The first turret head is movable selectively into first and second different angular positions around the first axis relative to the first turret headstock. The first turret head and first spindle headstock are movable relative to each other parallel to the first line in a manner that the first turret head can move up to and past the working end of the first spindle headstock without interference between the first spindle headstock and first turret assembly with the first turret assembly and first spindle headstock in a first relative state. The first turret assembly and first spindle headstock interfere with each other as the first turret assembly and first spindle headstock are moved relative to each other parallel to the first line in a manner that the first turret head moves up to the working end of the first spindle headstock with the first turret assembly and first spindle headstock in a second relative state.

    摘要: A lens shutter type of camera is disclosed in which a zoom lens is positioned in a lens block (1) which has a sector gear (15) rotatably associated with the lens block and with a rotatable cam ring (14). The cam ring and sector gear are rotatable in a substantially constant axial position. A movable finder optical assembly (8) and a movable strobe assembly (9) are movable in association with movement of the zoom lens. The zoom lens is movable between an extreme telephoto position and an extreme wide angle position, as well a into a fully collapsed lens position beyond the extreme wide angle position and a macro or close-up photographing position beyond the extreme telephoto position. When the camera is in its macro mode, a prism (P1) is inserted into the finder optical assembly to correct for parallax; the strobe assembly is moved to change its illumination angle; and an optical wedge (4e) is pivoted into the path between a light receiver (4) and a light emitter (3e). A single cam plate (53) is provided to move the finder assembly and the strobe assembly. The photographic aperture (22b) can be selectively closed by barrier plates (31a) when the zoom lens is moved into its fully collapsed position. A light intercepting assembly (210) is provided for preventing light from entering the photographic optical assembly via cam grooves (20 and 21). This intercepting assembly includes a flexible code plate (90) which surrounds a peripheral portion of the cam ring (14) and which provides positional information relating to the position of the zoom lens.

    摘要: A digital radio telephone gives information to user in speech form by using an advanced speech coder/decoder in a digital radio communication network. Such an advanced coder/decoder can reduce quantity of coded data to be stored. The digital radio telephone according to a first embodiment includes a speech coder/decoder, a speech information memory, a speech information retrieval table, an operational information controller, and a speech information reading section. A plurality of predetermined speech signals are stored in the speech information memory in coded form. The speech information retrieval table stores information for producing a voice message to the user using the items in the speech information memory. To give the voice message to the user, the information is read out by the operational information controller and necessary items of speech signals are read out by the speech information reading section in sequence according to the read information. The speech voice coder/decoder decodes the items so as to produce the voice message in the same way as with digital speech voice signals received by the digital radio telephone. According to a second embodiment, the user can store his own voice into the speech information memory in coded form, and when the user operates the telephone, the user will hear the voice messages in his own voice.
