Title: Diaphragm detecting method for continuous annealing line
Inventor: OKITSU HIROTO
IPC: C21D9/56
Filed: 1985-08-30
Abstract: PURPOSE:To evaluate the diaphragm on the surface of a material accurately and to prevent the yield of products from decreasing by irradiating light slantingly for the waving of the surface of the material which is caused in the heat treatment line of continuous annealing, etc., detecting its reflected light by an image sensor, and processing its detection signal. CONSTITUTION:The material 2 such as a steel plate which is carried out of a continuous annealing furnace is irradiated with light from light sources 5 and 6 through slit observation windows 9 and 10 slantingly in the width direction of the plate. The reflected light is detected by the image sensor 7. Its analog video signal is inputted to a primary processing means 203 through an A/D converter 202 to calculate data on the brightness on the surface of the material 2 and the data is stored in a memory. A width arithmetic means 204 reads out the data to calculate the width of the material and a meandering arithmetic means 205 calculates the extent of the meandering. A detection range arithmetic means 206 determines a diaphragm detection range R on the basis of the width of the material, a variation rate arithmetic means 207 finds the rate of variation in the brightness in the R, and a diaphragm width and area arithmetic means 208 calculates the mean value of the brightness to perform the evaluation 209 of the diaphragm.

Title: Semiconductor laser and fabrication thereof
Inventor: CHINO TOYOJI
IPC: H01S5/00
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To enhance the heat dissipation performance by burying the mesa of a surface emission laser in AlN. SOLUTION: A p-GaAs buffer layer 101, a p-type Bragg reflector 102, an active layer 103, an n-type Bragg reflector 104, and a cap layer 105 are formed on an n-GaAs substrate 100. An air post 107 is filled with an AlN layer 108. With such a structure, heat can be dissipated efficiently from the active layer 103 as compared with a case where the air post 107 is surrounded by the air or filled with a semiconductor. Consequently, the cooling effect of active layer 103 is enhanced by one or two digits or more as compared with a case where the air post 107 itself is cooled directly by the outer air or through the embedded semiconductor layer. This structure suppresses fluctuation of oscillation wavelength incident to increase in the oscillation threshold value or the temperature of active layer thus enhancing the maximum continuous oscillation temperature and the maximum optical output.
