Title: 발산영역을 가진 반도체 레이저 엘리먼트
IPC: H01S5/22
Filed: 2000-12-20
Abstract: 단일모드 광섬유에 접속하기 위한 반도체 리지 레이저는 좁은 평행영역, 발산영역 및 출력단면에 이웃한 넓은 평행영역을 구비한 리지를 갖는다. 레이저의 펌프영역은 리지의 전체 영역보다 작고, "T"자형태를 갖는다. 바람직하게, 상기 리지는 약 350 내지 550㎚의 깊이를 갖고, 상기 좁은 평행영역은 리지의 전체길이의 0.4배 이상의 길이를 갖는다. 출력에서 넓은 평행영역은 레이저가 낮은 열저항을 얻을 수 있도록 하며, 이는 낮은 작동온도, 레이저 공동에서의 낮은 출력밀도 및 낮은 비점수차의 원인이 된다.

Abstract: PURPOSE: A voltage type electric relay for motivating a single phase motor is provided to stabilize a voltage supply to a circuit element of the electric relay by using full-wave rectifying bridge diodes and filter capacitors. CONSTITUTION: A voltage type electric relay for motivating a single phase motor includes a power source(310), a triac(306) for applying an alternating current power to a start coil, a detector(322) detecting a voltage induced to the coil, a hysteresis portion(324), and a trigger(330) turning on and off the triac according to on and off control signals. The hysteresis portion outputs an on-control signal at starting position, an off-control signal to turn off the triac when the voltage from the detector reaches a predetermined off reference voltage, and an on control signal when the voltage from the detector falls below a predetermined on reference voltage. A switching diode(Dsw) is coupled between a gate node of the triac and a pickup coil for triggering the gate of the triac in series. The switching diode blocks a flow of a positive trigger current and lowers a level of an induced current due to a voltage drop across the diode for a negative trigger current.

A guide member(50) is located between the upper case and the lower case. A first passage(44) to circulate external air containing dusts and a second passage(46) to discharge purified air are formed in the guide member. A filter assembly(60) is installed between the guide member and the lower case. The filter assembly removes dusts or dirt from the sucked external air. Thereby, the inside of a cyclone dust collector body is cleaned easily and conveniently by opening and closing the cyclone dust collector body with a lever device.
