Title: Method for optimizing path length in optical waveguide and optical waveguide obtained by method thereof
Inventor: PIEERU RABEI
IPC: G02B6/122
Filed: 1995-01-17
Abstract: PURPOSE: To optimize a path length in an optical waveguide by optimizing the optical waveguide provided with a continuous curve variable at an optional point and an extension part to a nominal width accompanying the width. CONSTITUTION: Relating to this method for optimizing the path length in the optical waveguide provided with the continuous curve C variable at the optional point, the nominal width P0 and the extension part δP to the width P0 , the method is provided with a step for stipulating a function δP=f (C) to be a continuous function, that is the extension part δP, of the waveguide as the variable function (f) of the curve C. The method is easily executed by a normal masking lithography technique. In this case, it is preferable that the function (f) satisfies conditions indicated by an equation. In the equation, (k) is a constant. Especially, the function is the linear function of a curve: f (C)=k.C.. Then, by using the function, the method is especially easily executed.

Inventor: MITAMURA TOMOKAZU
IPC: H01M50/574
Filed: 1993-01-18
Abstract: PURPOSE:To prevent the rupture of a battery, by interrupting an electric path between a terminal board and a power generating element, by a first inversion deformation when internal pressure in the battery is increased, and breaking a safety valve, concurrently with a second inversion deformation, to exhaust gas. CONSTITUTION:When battery internal pressure is increased by a short circuit, overcharge, and reverse charge, the battery internal pressure is transmitted to a metal-made safety valve 1 through an air vent hole provided on a metallic lead fitting plate 4, a metallic perforated terminal board 3, and an insulating ring 2. In the valve 1, since its outer peripheral part is calked by a battery case, when the battery internal pressure is reached to a given value, a center part is rised upward, a folded part 1b is reversely deformed, a fused part S is separated, and the connection with the terminal board 3 is released to interrupt current. Next, when battery internal pressure is suddenly increased, the valve 1 is ruptured concurrently with the reverse deformation of the folded part 1a of the valve 1 to exhaust gas to outside a battery through an air vent hole provided on a terminal board 5. Consequently, the rupture of the battery can be prevented.

Title: Reformer
Inventor: AOYAMA SATOSHI
IPC: H01M8/06
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To raise the reforming efficiency while keeping the temperature of an outer wall at a lower temperature in a reformer using steam reformation and partial reforma tion in combination. SOLUTION: This reformer 10 is capable of increasing the efficiency of reforming reactions while keeping the temperature near an outer wall 12 at a low temperature by utilizing partial oxidation reforming reaction as the center and localizing a steam reforming reaction around the partial oxidation reforming reaction. That is, oxygen is fed from the inlet center of the reformer 10 to raise the oxygen concentration in the central region 14. Steam is fed along the outer wall 12 to raise the steam concentration in an outer peripheral region 16. In this state, the reformation of a hydrocarbon raw material is carried out to mainly cause the partial oxidation reforming reaction which is an exothermic reaction in the central region 14 and readily initiate the steam reforming reaction which is an endothermic reaction in the outer peripheral region 16 surrounding the central region 14.  Thereby, the partial oxidation reforming reaction can be promoted by the heat of reaction generated in the central region 14. On the other hand, the heat of reaction is absorbed to promote the efficiency of the steam reforming reaction when diffusing the heat of reaction produced in the central region 14. As a result, the temperature near the outer wall 12 is maintained at a low temperature.

Abstract: PURPOSE: To enable temperature adjustment of a heat exchanger without increasing the pressure losses of steam by constituting the heat exchanger such that portions of a heating tube extend into a combusting air passage so as to provide the heating tube with a temperature lowering function.  
     CONSTITUTION: Combustion gas 4 from a boiler is circulated in a combustion gas passage 3 defined by partition walls 1, 2. A partition wall 7 is disposed in a combusting air passage 5 defined by partition walls 2, 6 to divide the passage 5 into two passages 5A, 5B. Dampers 8, 9 are disposed at the upstream sides of the passage 5A, 5B, respectively, to control flows of combusting air 10 therein. A heat exchanger 11 has an inlet header 12 and an outlet header 13 which extend outwardly of the partition wall 1. The heat exchanger 11 is disposed in the combustion gas passage 3 and one 5A of the divided combusting air passages. Thus, portions of the heat exchanger 11 located in the combustion gas passage 3 act as heating tubes 11A while the remaining portions of the heat exchanger 11 extending into combusting air passage 5A act as cooling tubes 11B.
