    摘要: A light emitting element array has light emitting elements disposed on a base plate in an array and a rod-like converging lens is disposed adjacent and parallel to this array. The end surfaces of this rod-like lens are curved, or otherwise so shaped that light beams from the array are refracted towards the center of the lens, thereby increasing the relative distance on a target surface that can be effectively irradiated.

    摘要: In a signal detection circuit for an optical disk, a comparator converts an analog HF signal into a digital HF signal by using a slice level. A dropout detection circuit detects a dropout of the digital HF signal. A charge-pump circuit feeds back a slice-level control voltage to the comparator based on a result of the detection by the dropout detection circuit. A voltage follower holds and outputs a voltage stored in the capacitor. A switch is turned OFF when a dropout signal has been detected, and outputs to the voltage follower the voltage that has been stored in the capacitor during an ON state of the switch. A second switch is turned ON when a dropout signal has been detected, and applies an output of the voltage follower to the comparator.

    摘要: An LED lamp has a convex lens 3 which has an upper portion 5 and a lower portion 6. An upper curved surface 5A of the upper portion is different in shape from a lower curved surface 6A of the lower portion 6 so as to refract rays of light from an LED chip 2 more strongly than the lower curved surface 6A does. This avoids reflection of incident outside light toward a front and hence prevents misrecognition. An interface plane S1 between the upper and lower portions 5 and 6 of the convex lens 3 is located on an upper end face 2A to thereby prevent collection of outgoing light upon the interface plane S1 and generation of an irregular emission peak at the front.

    摘要: An electrode adapted for chromium plating from trivalent chromium baths which comprises a conductive base, an electrode material layer comprising iridium oxide formed thereon, and a porous layer formed on the surface of the electrode material layer. The porous can comprise an oxide containing at least one element selected from the group consisting of silicon, molybdenum, titanium, tantalum, zirconium, and tungsten. Use of this electrode for chromium plating reduces the oxidation of trivalent chromium into hexavalent chromium.

    摘要: A light source device with arrayed light emitting elements includes a base board on which a plurality of the light emitting elements are arranged in an array, a convergent rod lens provided parallel to the array of the light emitting elements, and a reflection casing for holding the convergent lens. The convergent lens and the reflection casing are integrally connected with an air-gap formed parallel to the cnvergent lens. The base board is secured upon being inserted into the air-gap. The convergent lens and reflection casing in the light source device with arrayed light emitting elements can integrally and simultaneously be molded by continuous two-color extrusion molding. Therefore, it is possible to manufacture the light source device with arrayed light emitting elements at lower cost and which can easily be assembly with a reduced number of parts.

    摘要: Valve operating apparatus is disclosed in which intake or exhaust valves for an internal combustion engine are operated by rocker arms driven by cams and have a hydraulically operated coupling mechanism for selectively connecting or disconnecting adjacent rocker arms to vary the operation timing of the valves under different engine operating conditions. The fluid circuit for operating the coupling mechanism contains a valve which is energized to a closed position during low-speed engine operation and de-energized to an open position during high-speed engine operation.

    摘要: A valve operating mechanism for operating a plurality of valves of a particular cylinder of an internal combustion engine includes a camshaft rotatable in synchronism with rotation of the internal combustion engine and having at least one cam. At least one of a plurality of cam followers slidably engages the cam for selectively operating the valves according to a cam profile of the cam. The cam followers are selectively interconnected and disconnected to operate the valves in different speed ranges of the internal combustion engine, the speed ranges including a range in which all of the valves remain inoperative. The camshaft has one or two annular raised portions in addition to the cam, and the cam followers include one or two cam followers which slidably engage the raised portion or portions. The valves remain inoperative by the annular portion or portions and are operated in a high-speed range by the cam, or selectively in low- and high-speed ranges by low- and high-speed ranges.
