Title: Semiconductor light-emitting device
Inventor: YAGI TETSUYA
IPC: H01L33/44
Filed: 1986-10-09
Abstract: PURPOSE:To introduce generated beams to the outside efficiently by forming the central sections of a clad layer, an active layer and a contact layer in multiple quantum well structure and shaping side sections except the central sections in a disordered region. CONSTITUTION:Currents flowing into a device flow only through a current path 7, a region not disordered (a central section 17, an n-type MQW clad layer 13 and an n-type InP substrate 1), by the difference of diffusion potential. Electrons injected from an n-side electrode 4 and holes from a region in which there is no SiO2 insulating film 2 between a p-side electrode 3 and a p-type MQW contact layer 11 are recombined in an active region 12 and converted into beams. Since the disordered MQW layer has a refractive index smaller than an original MQW layer, beams generated in the active region 12 are confined only in the region not disordered, and are not propagated in the cross direction of the device, thus efficiently introducing beams to the outside.

Filed: 1990-09-14
Abstract: PURPOSE:To automatically discriminate and visually check a graphic expressed by not-scale by providing this CAD system with means for comparing the 1st size value with the 2nd size value and aenerating information for displaying a graphic by not-scale, when both the values are different from each other. CONSTITUTION:Display shape data corresponding to a size value to be displayed are fetched from geometric data 1 stored in a memory 8 and the size value of a display shape is automatically calculated in each size value type. When the size value coincides with the calculated value as the result of their comparison, the display information of real size is formed, and when both the values are different from each other, not-scale display information is formed. Information formed by a size display part 6 is sent to a data display part 7, which forms display information including the information formed by the display part 6 and the shape data such as a graphic and displays the formed information. Consequently, a graphic expressed by the real size/not-scale can be visually checked and the generation of mal-function can be prevented.

Abstract: PURPOSE:To simply adjust a working point of the reverse rotation of a contact spring and to make such laborious management as strict selection of a movable pin etc. unnecessary by making it possible to adjust a load to the movable pin when the contact spring is turned in the reverse direction and the working point independently. CONSTITUTION:A load adjusting screw 24 is rotated by a switch unit 23 before the switch unit is fixed to a switch base 9' at an extended end of a spring receiver 7'. As a result, the spring receiver 7' is moved up and down at a fulcrum of a fixed point of a rivet 10', and a part of a contact spring 5 where it butts against a movable pin 3 is pushed up. Thus, a load where the contact spring 5 butts against the movable pin 3 when the contact spring 5 is turned in a reverse direction passing a point where a hook 8 of the contact spring 5 is caught by the spring 7' can be adjusted in a proper range. Then, in the state of a perfect product, a pressure is gradually added from a gas introducing hole 19 and a working point where the contact spring 5 turns in the reverse direction through a diaphragm 1 and the movable pin 3 is adjusted by an adjusting screw 12'. Thereafter, the pressure is gradually reduced to adjust a working point where the spring 5 is returned to the original position through the diaphragm 2 and movable pin 3 by a screw 13'.
