Title: Pollution progress test method for dust
Inventor: IKEO YOSAKU
IPC: G01N17/00
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To reproduce conditions approximating the natural state and to evaluate the resistance to pollution, in a short time, by repeating the spraying of a dust material to a sample and a plate provided above the sample and the sprinkling to the portion of the plate. SOLUTION: The pollution progress test of a material, such as concrete used for the outer wall of a house or a building, is conducted by using, for example a test body 3 fitted with a plate 2 simulating a window and made of a plastic which is easily stuck by dust above a sample 1. A water sprinkling 4 to the plate 2, spraying of a dust material with the prescribed composition on the faces of the sample 1 and the plate 2, and drying are repeated for the process with the test body 3 fitted to a rotating frame, for example. The color of the surface of the sample 1 is measured before and after the process to obtain luminosity difference, and the level of dust pollution of the sample 1 is decided.  Since water sprinkling is applied to only the portion of the plate 2, the difference caused by the magnitude of the water absorption coefficient of the sample 1 and the level of the hydrophilic/water repellent property of the surface can be clearly evaluated.

Title: Cooling method for gas turbine engine
Inventor: NIKKANEN JOHN P
IPC: F02C7/12
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To prevent complicated switching of a valve and lowering of efficiency of an engine during operation by letting an operating medium gas continuously flow through a heat exchanger between two points of a fan duct inner wall where a disadvantageous static pressure gradient is caused to be heat-exchanged with cooling air, and returning the high temperature air to an operating medium passage. SOLUTION: During operation, an operating medium gas flows along a primary passage and a secondary passage for the gas. Heat is carried to a cooling medium fluid flowing from various parts along a passage 74 to a heat exchanger 54. The cooling air is continuously passed through the heat exchanger under all operating conditions of an engine to continuously flow from a fan duct 46 through a passage 56. A passage for a heat exchanger system is extended to the heat exchanger through an inlet duct 76, and an inlet 58 including a first pipeline 82 and a second pipeline 84 and further extended through an outlet 64. The passage 56 is not intercepted under all operating conditions. The valve operation is not needed for regulating the flow. Thus, the cooling system is simplified, and in the heat exchange system, complicatedness of a valve and a control means can be prevented.

Title: Hydrogen supplying device
Inventor: MORISHIMA SHINGO
IPC: C01B3/00
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To stably supply a sufficient quantity of hydrogen even in the case of cold starting.
