Abstract: PURPOSE:To obtain a branch circuit to be easily coupled with an optical fiber, by forming three-layer slab waveguide having a Y branching pattern on a quartz base plate in concave shape, putting the base plate between a pair of semicylindrical quartz base materials having a groove in which the concave shape waveguide is to be stored and applying the whole unit with wire drawing after inserting it into a hollow quartz tube. CONSTITUTION:A Y branching pattern 12 for the recessed waveguide consisting of a core layer and clad is formed on the quartz base plate 6 and a square groove 13 is formed in the center part of the branch of the pattern 12. The base plate 6 is put on a semicircular base material 14 obtained by forming a Y-shaped groove 12' storing a pattern corresponding to the pattern 12 and a groove 15 corresponding to the groove 13 of the base plate 6 on one of a pair of semicylindrical quarts base materials 14, 14 and a base material 14 on which only the groove 15 is formed, and glass 18 consisting of SiO2+B2O5 is applied to the groove 15 to insert the base plate 6 between the base materials 14, 14. Subsequently, the quartz tube is heated and applied with wire drawn to prepare a fiber and the glass 18 is etched by using 50% HF, so that a single or multi-mode branch circuit in which the core 19 is covered with the clad 20 is obtained at low insertion loss.

Title: Method for producing concentrated extract from herb having drug action
Inventor: OOTANI KOUKICHI
IPC: A61P35/00
Filed: 1983-05-10
Abstract: PURPOSE:To obtain the titled extract economically in an industrial scale, by concentrating the decocted liquid of a gramineous plant having various drug actions, mixing the liquid with a medium effective for raising the boiling point to obtain the first concentrated extract, increasing the viscosity of the original concentrated liquid with the first extract, and concentrating the obtained mixture to afford the final concentrated extract. CONSTITUTION:Decocted and concentrated liquid of a gramineous plant such as rice, barley, adlay, etc. is added with a medium effective for raising the boiling point (e.g., 0.1% sodium carbonate, superheated steam, etc.), and heated at an effective temperature lower than the caramelization temperature (200 deg.C), e.g. at 120-160 deg.C for 6-12hr to obtain the first concentrated extract. A concentrated extract prepared by the same process is added with a small amount of the above first concentrated extract to raise the viscosity, and the mixture is heated, added with hot water, and boiled. The supernatant liquid is separated and again concentrated by boiling to obtain the final concentrate. A large amount of a concentrated extract can be prepared effectively, with a simple procedure, without using a particular solvent, by raising the viscosity of the decocted solution, and concentrating the solution at a high temperature.

Title: Power recovery processing method using computer
Inventor: YOSHIDA OSAMU
IPC: G06F12/16
Filed: 1983-05-09
Abstract: PURPOSE:To check assuredly the support of a battery by providing a comparator which compares the highest working voltage of a circuit that is supported by a battery with the battery voltage and reading the comparator by a computer when the supply of power is recovered. CONSTITUTION:The battery voltage VB sometimes drops less than the minimum necessary voltage VBmin with increment of the service interruption period when a part of a computer is supported by a battery B in a power failure mode. Therefore the reference voltage V- is produced by resistance R2 and R4 and supplied to a non-inverse input terminal (-) of a comparator COP. The voltage -V is set so that a status signal VS, i.e., an output is changed to a low level from a high level when the voltage VB is equal to the voltage VBmin. A computer reads the signal VS in a short time from the recovery of power supply an decides the level of the VS. If the signal VS is set at a low level when the supply of power is recovered, the support of battery is impossible. In this connection, the computer performs the initial processing equal to that carried out when a power supply is applied. While it is decided that the support of battery was perfect if the signal VS is set at a high level when the supply of power is recovered.
