Title: Method for solving winding of bandlike rubber on roll
Inventor: HAGIWARA YOSHIAKI
IPC: B29C43/24
Filed: 1987-02-03
Abstract: PURPOSE:To solve a trouble of winding of a bandlike rubber on a roll automatically without stopping the working line by a method in which when a bandlike rubber is cut halfway and winds round on a roll, the distance between the rolls of one pair is enlarged, whereby the rubber is separated by being cut at the part of difference in level of the bandlike rubber having been formed. CONSTITUTION:When the tip of a bandlike rubber S which has wound around the periphery of a roll 2 reaches the detecting range of a photoelectric sensor 5, the winding of the bandlike rubber S on the roll 2 is detected. When the distance between two rolls 1, 2 is enlarged, while separating the roll 2 from the roll 1, a sharp difference in level 12 is generated in between a thin part S1 and a thick part S2. The tensile stress generated inside of the bandlike rubber due to the heat shrinkage in contact with outside atmosphere is concentrated on the difference in level 12, and the rubber is cut off. The thick part S2 which is on the rear side from the part of the difference in level is separated off from the roll 2 by its dead weight, and hangs down from the rolls 1, 2, whereby the winding round of the bandlike rubber on the roll 2 is removed. When the thin part S1 passes the detecting range of a photoelectric sensor 5 by the rotation of the roll 2, the photoelectric sensor 5 detects the separation of the bandlike rubber S, and the distance between the rolls 1 and 2 is restored to the preset valve.

Title: Semiconductor luminous element of 3-5 group compound and its preparing method
Inventor: YASUDA MICHIROU
IPC: H01L21/28
Filed: 1980-02-28
Abstract: PURPOSE:To obtain a luminous efficiency close to the theoretical value by preparing an electrode of P layer of III-V group compound as a three layer structure and settings a Ta layer including N in the intermediate layer therein. CONSTITUTION:An N type GaP 32 and a P type Gap 33 containing Zn and O are layered on an N type GaP substrate 31. An Au-Ge alloy electrode 34 is attached to the substrate 31. Then, an Au-Zn alloy 35a containing 1wt% of Zn, and Ta 39, Au 35b containing N are piled up on said P layer 33. Particularly, in case of forming a layer 39, a Ta is attached by vapor deposition at approximately 10<-4>-10-6 Torr by intrducing N after evacuation. After ohm contact with heat treatment, if the etching is performed selectively, the exfoliation of the layer 39 and 35 do not occur. After chippings, the side surface of the P-N junction is made coarse to increase the luminous efficiency and adhered to a header 36 with a conductive pastes 37 to connect a wire 38. Since the layer 39 disturbs the migration of Zn, Ga and P at heat treatment, a complex oxide film does not occur on the Au layer 35b, but a good junction is obtained. Further, since the deterioration of the crystallivity on GaP surface can be prevented, the luminous efficiency close to the theoretical value is obtained and the yield is also increased.

Title: Joint part structure for metal flexible tube and connecting method thereof
Inventor: KODAMA TAKANORI
IPC: F16L33/26
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To form the joint part structure so that the fluid contacts with the only inner layer tube and that a contact of the fluid with an overlapped clearance of the inner layer tube and the outer layer tube is prevented by inserting an inner layer tube extension part into an installation hole of a joint fitting so as to pass through it, and forming a seal surface part obtained by bending the passing end of the inner layer tube extension part of the only inner layer tube. SOLUTION: An inner layer tube extension part is inserted into an installation hole 16 of a joint fitting 14 so as to pass through it, and a seal part 19 is provided with a seal surface 19a formed by bending the passing end of the inner layer tube extension part, and the seal surface part 19a is formed of the only inner layer tube 20. Since the only inner layer tube 20 contacts with a seal receiver surface of the joint fitting 14, and an end of an outer layer tube 22 is terminated in the installation hole 16 of the joint fitting 14, for example, the outer layer tube 22 is always coated by the inner layer tube 20 at the seal receiver surface part of the joint fitting 14. Consequently, the fluid does not come into contact with the outer layer tube 22.  A seal part of the metal flexible tube 12 is formed of the only inner layer tube 20 without generating a clearance between the inner and the outer layer tubes so as to improve the corrosion resistance of the joint part.
