CONSTITUTION:The emitter area of a TR Q4 is a multiple of N1 of that of a TR Q1, and the emitter area of a TR Q2 is a multiple of N2 (however, N1XN2=N>1) of that of a TR Q3. A reference voltage V01 outputted at an output terminal 1 is a reference voltage V02 via an emitter follower stage by a TR Q7 and the reference voltage V02 is level-shifted by a TR Q8 to be a reference voltage V03. Since each reference voltage is expressed in a form of sum of weight between a base-emitter voltage V S1BE of a TR having a negative temperature coefficient and a thermal voltage VT having a positive temperature coefficient, each reference voltage has a prescribed output voltage in setting properly a resistance ratio (R4/R3) deciding the weight coefficient of the voltage VBE, resistance ratios (R4/R3) and (R2/R1) deciding the weight coefficient of the voltage VT, and the said area ratio of the emitter and a prescribed temperature characteristic is provided.

Title: Manufacture of semiconductor laser
Inventor: ARIMOTO SATOSHI
IPC: H01S5/00
Filed: 1991-03-29
Abstract: PURPOSE:To improve the regrown interface characteristic of a contact layer without generating a thermally deformed layer by removing the part of a semiconductor layer corresponding to the crest section of a ridge by selective etching after the semiconductor layer is grown by epitaxial growth and forming a current block layer. CONSTITUTION:A double hetero-structure is composed of a lower clad layer 2 of the first conductivity type, active layer 3, and upper clad layer of the second conductivity type. Then only the layer 4 is worked to a ridge-like shape by leaving the layer 4 by a prescribed thickness only. After forming the ridge 9b, a semiconductor layer 7b of the first conductivity type which becomes a current block is formed so as to cover the entire surface of the ridge 9b. Then the current block layer 7b is formed by only removing the layer 7b from the crest section of the ridge which becomes a current path by selective etching. Since the current block layer 7b is formed without performing selective growth using a dielectric film, no thermally deformed layer is formed and the regrown interface characteristic of a contact layer 8 is improved when the layer 8 is regrown.

Filed: 1989-04-13
Abstract: PURPOSE:To secure the safety of an IC in the next process by arranging a potential sensor and a lock mechanism on the downstream side of a discharge circuit. CONSTITUTION:At first, a mounting substrate 6 is inserted along the substrate guide pin 4 of a dynamic checking stand 1 and, by operating a substrate fixing lever 3, a contact pin 2 is perfectly brought into contact with the land of the mounting substrate 6 to form a check circuit. After a dynamic checking is completed, when a power supply switch 5 is turned OFF, a discharge circuit is formed from a discharge resistor 7 and an earth 10 and charged voltage begins to discharge. Since an output contact 8a is in an open state when the charged voltage is equal to or more than the set value of a voltage sensor 8, no voltage is applied to a lock apparatus 9 and the lever 3 is locked to be impossible to operate. When the charged voltage becomes below the set value of the sensor 8, the contact 8a becomes a contact state and, therefore, the lock apparatus is released and the lever 3 can be operated.
