Title: Shaped joint material for hot setting
Inventor: OUCHI TATSUYA
IPC: B22D11/10
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain a shaped joint material for hot setting scarcely smoking when set while hot without causing the cracking due to a change with time. SOLUTION: This shaped joint material for hot setting is obtained by forming a kneaded material prepared by adding an acrylic emulsion as a binder in an amount of 5-60 wt.% expressed in terms of outer percentage to a raw material mixture comprising 60-97 wt.% refractory raw material powder and 3-40 wt.% frit such as a lead borosilicate glass, a borosilicate glass or a zircon frit and drying the formed product. Since a long time is required for ignition and smoking when set while hot, a user is capable of leaving the job site during the time. Since the working environment is scarcely adversely affected and a change with time is slight, cracking is scarcely caused in the shaped joint material. Thereby, the shaped joint material can safely be used.

Title: Connecting method of single polarization optical fiber
Inventor: SHIMIZU MASANOBU
IPC: G02B6/38
Filed: 1982-01-11
Abstract: PURPOSE:To obtain an optimum connection state, by measuring quntities of leakage from single polarization optical fibers. CONSTITUTION:In case that a pair of single polarization optical fibers 1a and 1b are connected, their connection faces are matched to each other, and a light 4 from a light source 3 is made incident to the incidence end of the optical fiber 1a through a polarizer 2 while rotating the optical fiber 1a or 1b. This incident light is emitted from the exit end of the optical fiber 1a and is made incident to the incidence end of the optical fiber 1b. If the axis of polarization of the light incident to the optical fiber 1b coincides with that of the optical fiber 1b, this light is incident to the core of the optical fiber 1b and is not leaked to the external; but if the axis of polarization of this incident light does not  coincide with that of the optical fiber, the incident light is scattered or leaked  to the outside of the optical fiber 1b. Consequently, the quantity of light leaked  from the optical fiber 1b is measured to discriminate the coincidence or incoincidence of the axis of polarization. Thus, optical fibers are connected after  confirming the coincidence of the axis of polarizalion to obtain an opitmum  connection state.

Abstract: PURPOSE:To have a high quality, thin layer grown by a method wherein a procedure is repeated several times wherein a first layer is epitaxially grown to be subjected to photoetching resulting in a lattice, groove, or dot shaped pattern and then another layer is epitaxially grown over them to be subjected to polishing, in a process for epitaxially growing a semiconductor crystal on an insulator substrate crystal. CONSTITUTION:A GaAs crystalline layer 2 is epitaxially grown on a crystalline insulator substrate 1 of saphire, spinel, or beryllia. The grown layer 2 characterized poor because of a high lattice defect concentration is coated with an SiO2 film 3 and a prescribed pattern is obtained by photoetching. The grown layer 2 is then subjected to etching using a liquid mixture of NaOH and H2O2 whereby the layer is totally removed except where some insular regions are left. A GaAs layer 4 is then epitaxially grown exemplifiedly of Ga-AsCl3-H2 making use of disproportionation. Thus, the side-wise spread component is made larger than the thicnkess-wise grown component, which reduces the lattice defect concentration, and then the surface is polished flat. The steps above are to be repeated several times.

Title: Electrode plate for lead storage battery and manufacture thereof
Inventor: FUKUDA SADAO
IPC: H01M4/20
Filed: 1985-01-11
Abstract: PURPOSE:To improve the rate of utilization of an active material as well as a cycle life by providing a proper diameter hole in any one of positive and negative electrode plates or in both of them. CONSTITUTION:A hole of a diameter of from 0.2 to 2.0mm is provided in any one of positive and negative electrode plates for lead battery or in both of them. With such arrangement, even if lead sulfate is produced due to electrical discharge, sulfuric acid can still be supplied into an electrode surface by drilling a hole having a size not to permit said lead sulfate to fill it therewith, e.g., 0.2mm even if the lead sulfate is produced on the electrode plates, whereby utilization of an active material is improved. But, an excess size of the diameter of the hole drilled in the electrode plate causes an amount of filling of the active material in the electrode plate to be reduced, and hence discharge capacity per one sheet of the electrode plate is reduced even if the utilization of the active material is improved. Therefore, the size of the hole is about the thickness of the electrode plate to the utmost. Moreover, filling a hole of a diameter of from 0.2 to 2.0mm with a material of a property to suction liquid facilitates an electrolytic solution to be held in the hole for enabling overcharge life to be also improved.

Title: Running plate thickness changing method of tandem rolling mill
Inventor: KITAMURA KUNIO
IPC: B21B37/24
Filed: 1984-01-13
Abstract: PURPOSE:To prevent a break of a plate, a squeeze, etc. by ending a change of a plate thickness of the j-th stand before a plate thickness change starting point which has passed through the j-th stand reaches the (j+1)-th stand. CONSTITUTION:A roll gap is changed in order to change an outlet plate thickness of the j-th stand to a plate thickness hjII of the second strip from a plate thickness hjI of the first strip, and a roll speed is controlled so that a length Lsj of a plate rolled during that time becomes smaller than a stand interval Lj. Accordingly, before the plate thickness changing part reaches the (j+1)-th stand, a control for changing the plate thickness in the j-th stand is ended, and the plate thickness changing part does not extend over both stands. In this way, a tension variation in case of changing a running plate thickness is reduced remarkably, and a break of a plate due to an excessive tension, a squeeze due to a too small tension, etc. are prevented.
