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： 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： 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： 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.
