IPC: H01S5/20
Filed: 1989-04-28
Abstract: PURPOSE:To improve the accuracy of control of an active region by a method wherein a semiconductor laser is constituted in such a way that a film which is used as a diffusion source ts formed and after an opening part is formed in this film and the opening part is covered, an impurity is diffused from the film which is used as a diffusion source over a prescribed region of a semiconductor layer and the film used as a diffusion source becomes an insulating film. CONSTITUTION:An N-type AlxGa1-xAs layer 5, a quantum well active layer 6 and a P-type AlxGa1-xAs layer 7 are grown successively on an N-type GaAs substrate 4 and thereafter, an Si film 2 is formed on the whole surface of the layer 7. Then, the film 2 is selectively removed and after a contact hole 10 is formed, an Si3N4 film 18 is formed in such a way as to cover the film 2 and the hole 10 and this film 18 is selectively removed. Then, when a diffusion is performed, Si diffused regions 15 are formed on the sides of the end surfaces of the outside. At this time, Si is diffused in the layer 6, disordered regions 16 are formed and an active region 17 is formed between the regions 16. Then, after the film 18 is removed, a Ti-Au film is formed and the Ti-Au film is selectively removed to form an Ni-Au-Ge-Au film on the substrate 4. Whereupon, P and N electrodes 12 and 13 are formed. Thereby, the active region is formed in a self-alignment manner, the high-accuracy active region is obtained and the manufacture of a highly reliable semiconductor laser becomes possible.

IPC: H04N1/407
Filed: 1983-06-20
Abstract: PURPOSE:To read various originals different from the range in density with high picture quality by normalizing automatically a density read from the original into a density region inherent in the device. CONSTITUTION:A picture signal proportional to the reflectance of an original 2 is inputted to a density normalizing circuit 7 via an automatic level set circuit 6. The density normalizing circuit 7 consists of an automatic level control section 8, a parameter processing section 9, and a parameter converting section 10. An input device 11 inputs a density parameter DW (white parameter) and a DB (black parameter) to the normalizing circuit 7. The normalizing circuit 7 normalizes automatically the density read from the original to the density region inherent in the device within an upper and a lower limit set by the input device 11. Through the constitution above, various originals with different density range are read with excellent picture quality without troublesome operation such as manual adjustment of the gain and bias of the signal system by having only to input a proper density parameter.

Title: Clutch
Inventor: MACHII RITSUO
IPC: B41J33/52
Filed: 1991-04-18
Abstract: PURPOSE:To keep torque of a clutch constant even when environmental temperature changes in the clutch for taking up a ribbon to be used in a thermal transfer recording device. CONSTITUTION:A gear pulley 4 which obtains power from a drive source is engaged with a clutch base 6 to which a felt 5 as a friction member is stuck. From the upside thereof, an adjusting member 3 and a compression spring 2 expansible or contractible dependent on temperature are inserted in an axis 6a of the clutch base 6. Further, a cap 1 is inserted with pressure in an axis 6b of the clutch base 6. Accordingly, at a high temperature where friction of the gear pulley and the felt becomes small, the adjusting member expands so as to increase the spring constant of the compression spring and make torque of the clutch constant. On the contrary, at a low temperature where the friction becomes small, the adjusting member contracts so as to decrease the spring constant of the compression spring and make the torque of the clutch constant, so that the torque of the clutch can be kept constant even when the environmental temperature changes.

Title: Method and device for welding and connecting multifiber optical cable
Inventor: IDE TAKASHI
IPC: G02B6/255
Filed: 1988-05-09
Abstract: PURPOSE:To stably obtain optical fibers of a low connection loss by setting the heating time in such a manner that the average value of the individual loss when the fibers are heated for the prescribed heating time attains a min. value. CONSTITUTION:The optical fibers on one side are moved in an optical axis direction while said fibers are heated to the optical fibers on the other in order to pressurize the optical fibers 1, 2 in the optical axis direction. The optimum value of the moving quantity is set by welding conditions such as the spacing between the end faces, material quality and diameter of the fibers. The connection losses in the spacings between the end faces of the individual fiber can be calculated in accordance with the prescribed data if the moving distance of the fibers is designated as M and the spacing between the end faces as (d) and when the pushing length L of the end faces of the respective fibers is determined. The heating time to minimize the connection loss is, therefore, set by previously storing the moving quantity M, the spacing (d) between the end faces of the fibers and the connection loss alpha into the memory of a processor.
