Abstract: PURPOSE:To realize a quantum fine line or a quantum box which is high in light emitting efficiency and whose active region is large by a method wherein a superlattice structure is cut so as to be 2mum or so thick, and it is thermally treated as covered with SiO2, Si3N4, or the like. CONSTITUTION:A lower clad layer 2 of AlXGa1-XAs (x=0.3) 2mum in thickness, a superlattice layer 3 640Angstrom  in thickness, and an upper clad layer 5 of AlXGa1-XAs (x=0.3) 1mum in thickness are successively laminated on a GaAs substrate 1. Then, a ridge structure 2mum in width and 1.2mum in height is formed on the surface of a growth wafer through etching, and then SiO2 is deposited on the surface of the ridge structure. The growth wafer is laid on another GaAs wafer making its SiO2 coated face overlap the GaAs wafer, which is thermally treated in a hydrogen atmosphere under such a condition that a temperature-rise rate, a heat treatment temperature, and heat treatment time are set to 30 deg.C/second, 950 deg.C, and 30 seconds respectively. By this heat treatment, the mixed crystallization of a superlattice part starts partially from its side in contact with an SiO2 layer 6 in a lateral direction and a superlattice structure is left only near the center of the ridge structure.

Title: Production of flexographic printing block
Inventor: GELBART DANIEL
IPC: B41C1/045
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To enhance durability at the time of use in printing work by using a computer controlled laser cutting tool when an elastomer layer is subjected to image cutting, stripping unnecessary materials and hardening an adhesive layer. SOLUTION: A flexographic plate is produced by cutting the outline of a protruding region mechanically and stripping unnecessary elastomer wherein an elastomer layer 2 is fixed to a dimensionally stabilized substrate 1 using a vulcanizable/curable presuure-sensitive adhesive layer 3. An upper layer 4 can be used for imparting special characteristics like a hydrophilic surface for good wetting by an aqueous coating. The substrate 1 is made of metal, preferably polyester, and after a desired outline is cut using a computer controlled laser cutting tool, unnecessary material 5 is stripped off and residual elastomer adheres to the substrate 1 through radiation or heating thus obtaining adhesive resisting against corrosion by a solvent existing in the coating.

IPC: H01M10/14
Filed: 1980-12-26
Abstract: PURPOSE:To prevent any separator from becoming loose and being shifted, and prevent any short circuit or the like which might be caused due to jumping of a plate by joining the side surfaces of separators, between which the plate is interposed, by use of an acid- and oxidation-proof tape provided with an adhesive. CONSTITUTION:A separator 4 on which a glass mat 3 is affixed is interposed between a negative and a positive plate 1 and 2 so that the mat 3 touches the plate 2, thereby making a unit. Then, a necessary numbers of units are superposed so as to form a plate group. Next, the side surfaces of separators 4, between which each positive plate is interposed, are joined with a soft adhesive tape 5, which is made of polypropylene or the like having acid and oxidation resisting property; a pressure sensitive adhesive or the like is stuck on the back of the tape 5. Since the separators 4 are larger than the plates 2, they are joined with the tape 5 placed on their side surfaces by applying slight pressure by means of a movable roller. Owing to the above constitution, the separator 4 can be prevented from becoming loose and being shifted. Consequently, any short circuit which might be caused between the plates 2 due to jumping of the plate 2 can be prevented.

Title: Image forming device
Inventor: SUGANO MASASHI
IPC: G03G15/20
Filed: 1989-07-20
Abstract: PURPOSE:To complete the switching of a sorter until a subsequent transfer sheet comes after a proceeding transfer sheet is ejected even when two or more identical images are formed in an image area by setting the speed that a carrying device carries a subsequent transfer sheet lower than the speed that the device carries a proceeding transfer sheet. CONSTITUTION:To copy and form two images, a current mode is checked to be a sort mode where the sorter 18 is used. In the sort mode, a carrying belt 23 is normally driven until the first proceeding transfer sheet passes by a fixing roller 26 out of two transfer sheets on which two identical images formed at the same time are transferred in the image area of a drum 9. After another transfer sheet passes by the fixing roller 26, two-image forming and copying is performed wherein the carrying belt 23 is driven at a speed lower than usual. consequently the time required for the subsequent transfer sheet to come to the sorter 18 is lengthened, and the switching of the sorter 18 completed before the sheet arrives.
