Title: Multiple quantum well semiconductor laser
Inventor: WATANABE HIDEAKI
IPC: H01S5/00
Filed: 1985-11-19
Abstract: PURPOSE:To improve characteristics such as decrease in threshold current value, by gradually decreasing the thickness and the forbidden-band width of a well layer from the vicinity of a clad layer to the center of an active layer, thereby confining carriers in the active layer and laser light sufficiently. CONSTITUTION:Well layers 21-23, which have the thickness thinner than the de Broglie wavelength of an electron wave, and a barrier layer 24, which has a broader forbidden-band width than that of the well layers 21-23, are alternately laminated in a multiple quantum well structure. An active layer comprises said structure 20. In this semiconductor laser, the forbidden-band width of the laminated well layers 21-23 and the thickness of the laminated well layers 21-23 are gradually increased from the central part of the active layer toward the outside. For example, in the case of an AlGaAs/GaAs multiple quantum well semiconductor laser, the composition and the thickness of each layer are specified as follows: for the quantum well layer 21 at the central part of the quantum well structure, GaAs and 30Angstrom ; for the quantum well layer 23 adjacent to clad layers 25 and 26, Al0.08Ga0.92As and 90Angstrom ; and for quantum well layer 22 between both quantum layers 21 and 23, Al0.04Ga0.96As and 60Angstrom .

Title: Surface polishing device
Inventor: SUGIYAMA MISUO
IPC: B24B37/015
Filed: 1986-10-29
Abstract: PURPOSE:To sustain the flatness with a high degree of accuracy, by filling polishing liquid in a liquid tank to such a degree that a stool and a pressurizing plate are sunk into polishing liquid during the workpiece is polished, so as to prevent the temperatures of a stool and a pressurizing plate from rising and to prevent occurrence of the difference in pressure between the upper and lower surfaces. CONSTITUTION:A drive source 12 rotates a liquid tank 11 together with a stool 13 in the liquid tank 11. In this condition, a pressurizing plate 22 is lowered so that a workpiece 23 bonded to the lower surface of the pressurizing plate 22 is made into press-contact with the upper surface of the stool 13 on rotation under a predetermined pressure in order to polish the workpiece 23 by the stool 13. Meanwhlie, polishing liquid 14 is circulated from the liquid tank 11 by means of a pump 18 through a suction pipe 16, a temperature managing device 15 and a supply pipe 17 to cool the stool 13 and the workpiece by the polishing liquid 14 so as to prevent a temperature rise of the stool 13 and the transmission of heat to the pressurizing plate 22. As a result the polishing liquid whose temperature is raised, is cooled while it circulates through the temperature managing device 15, thereby it is possible to maintain the liquid at a set temperature.
