Title: Stirling engine
Inventor: NAKANO MASAMITSU
IPC: F02G1/053
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To solve problems that gas is leaked from a clearance of a cylinder and a piston, friction loss of the cylinder and the piston is great, baking is caused, heat escapes from a cylinder wall, and furthermore oil enters the cylinder, the cylinder is heavy and difficult to bend, and horizontal direct input and output from the piston is difficult. SOLUTION: A cylinder and a piston are formed in a shape of bellows, or the cylinder is partitioned by a diaphragm so that a clearance of the piston and the cylinder is removed, gas is not leaked, and oil does not enter the cylinder. Furthermore, friction loss energy of the cylinder and the piston is eliminated by removing the cylinder. Heat loss is prevented by thermal insulating effect of the bellows piston. The cylinder and the piston are not baked because the cylinder and the piston do not conflict each other. This stirling engine can be light-weighted because the cylinder is eliminated. Direct input and output from the piston bent in a bellows shape enables the manufacture of any types of Stirling engines.

Abstract: PROBLEM TO BE SOLVED: To obtain a gas corrosion tester in which the data of all samples arranged in a corrosion resistant pipe can be employed as an object of evaluation by forming protrusions for disturbing the gas flow on the inner surface of pipe at the end part on the gas flow-in side. SOLUTION: A corrosion resistant pipe 1 surrounds an electric furnace 6 and a mounting table 3 is disposed in the pipe 1 through a mullite tube 2. The pipe 1 is made of a material not corroded by a test gas, e.g. quartz glass, while the mounting table 3 is made of refractory brick having semicircular cross-section extending along the inner surface of tube 2. Protrusions 4 for disturbing the gas flow are formed on the inner surface of pipe 1 at the end part on the gas flow-in side. When a test gas is fed continuously from one end of mounting table 3, the test gas flows out from the opposite side of pipe 1. Upon elapse of a predetermined time, the sample 5 is taken out and weighed. Corrosion resistance of specific sample is evaluated by determining the order of each sample from the gas flow-in side, and weight reduction per unit weight of each sample due to due corrosion.
