Title: Coupling method between optical waveguide and optical fiber
Inventor: EDAHIRO TAKAO
IPC: G02B6/13
Filed: 1981-08-24
Abstract: PURPOSE:To realize a stable coupling method with a low loss between an optical fiber and an optical waveguide, by cutting a groove at a desired part of the optical waveguide with an optical means and loading an optical fiber into the groove. CONSTITUTION:The CO2 laser light 34 of 5W is stopped down through a lens 35 and irradiated on the porous glass multilayered films 31-33 which are previously laminated on a glass substrate 30 by a CVD process, a hydrolysis reaction, etc. The porous film absorbs the light 34 and volatilized to form a groove 36. Then the substrate 30 is heated up to about 1,400 deg.C. Thus the porous glass film is changed transparent to be used as an optical guide film, and the groove 36 is left as a groove 40.

Title: Automatic operation system for electronic computer system
Inventor: ITO MASARU
IPC: G06F11/34
Filed: 1991-05-08
Abstract: PURPOSE:To attain an automatic operation system together with reduction of the labor for an electronic computer by securing the automatic operation of a console despite the various and complicated executing conditions. CONSTITUTION:A register list 105 describes a console operation 1 related to the operation of an electronic computer system and the executing conditions of the operation 1 in a form of a high freedom degree. A condition monitoring/ operating part 104 collates the working operation information on the computer system stored in a logging file 106 with the contents of the list 105 at each fixed time interval. When the executing conditions are satisfied, the corresponding operation 1 is carried out by a program resident in a CPU. If the executing conditions are not satisfied, the unsatisfied one is extracted out of those conditions necessary for execution of the operation 1. If this extracted condition can be satisfied with the automatic execution of a console operation 2, this operation is carried out.

Title: Joining method of members by stud welding
Inventor: JOGAN SHIGETOSHI
IPC: B23K9/20
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a joining method of members by stud welding, by which the generation of a recess on the opposite surface of the joining of a sheet shaped base material or the generation of a harmful thermal deformation caused by a thermal effect on the joining part of the sheet shaped base material, can be prevented or reduced when joining by stud welding a stud material made of metal to the sheet shaped base material made of thin metal. SOLUTION: A projecting part 3 for joining is formed on the joining portion of the joining surface 1a of a sheet shaped base material 1, and while arranging vertically a stud material 2 to the projecting part 3 for joining, stud welding is performed. Since the opposite surface 1b of the joining of the sheet shaped base material 1, is hardly affected by a thermal effect, the generation of a recess caused by solidification and shrinkage after welding on the opposite surface 1b of the joining or the generation of a thermal deformation on a joining part, can be prevented or reduced.

Title: Superfine al grain
Inventor: KIYO HEISHIYA
IPC: B22F9/30
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To easily control crystal orientation and to obtain superfine Al grains, in which various operations, controls, applications and developments, etc., are made possible, by disposing metastable Al oxide grains on an amorphous carbon film and irradiating the metastable Al oxide grains with an electron beam in a vacuum atmosphere. SOLUTION: Metastable Al oxide grains are disposed on an amorphous carbon film 1, and the metastable Al oxide grains are irradiated with an electron beam 3 in a vacuum atmosphere. The metastable Al oxide grains 2 are activated, and Al and O as component elements are scattered around. Because the metastable Al oxide grains 2 are disposed on the amorphous carbon film 1 having reducing action, scattered oxygen is reduced and Al alone is allowed to adhere as cluster to the neiboring carbon film 1, by which fine Al grains are formed around the metastable Al oxide grains 2. The size of the fine Al grains is regulated to 10-30nm. By this method, an Al multiple twin pentagonal decahedron 4a, surrounded by [111] faces, can be obtained. It is preferable to regulate the intensity of the electron beam 3 to be applied to (1.0×10<19> to 1.0×10<21> )e/cm<2> .sec.
