Filed: 1982-04-19
Abstract: PURPOSE:To obtain a mask whose surface has no reflecting property, by covering the surface of a nickel alloy plated film, with a nickel alloy oxide by 300Angstrom -500Angstrom . CONSTITUTION:Soda glass is immersed and treated in 10N NaOH, and after water washing is treated by a mixed solution of 1g/l SnCl2 and 1cc/l HCl, then washed with water, and after that, is treated by ''Red Sumer'', and after water-washing, nonelectrolytic nickel phosphate plating is performed by 4,000Angstrom .

IPC: G05B23/02
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To improve diagnostic accuracy of a diesel engine simply and economically. SOLUTION: Possibility of generation of abnormal condition is calculated by a computer 1 from a difference between automatically detected value of the first operational condition out of operational state having relationship to an abnormal state of an engine and a reference value and the grade of relationship between cause and effect, and the second operational condition (not detected automatically) relating to the abnormal condition is displayed by CRT2, and a person checks this state and a difference between those conditions and the reference condition is inputted from a keyboard 3 and the computer 1 makes calculation again including the difference. Therefore, since the entire operational conditions relating to abnormal state are included in the calculation in a diagnosis, the reliability of the computed results is high.  Since there is no necessity to increase the number of sensors extremely and/or to furnish expensive sensors, economical condition may be achieved.

Title: Fuel cell
Inventor: KOBAYASHI SHIGEYOSHI
IPC: H01M8/24
Filed: 1987-03-23
Abstract: PURPOSE:To improve the performance, service life and reliability of a fuel cell by letting oxidizer gas to flow in adjacent unit cells in crossing directions to each other so as to make temperature distribution in the cell uniform. CONSTITUTION:For making flows of oxidizer gas 3 to be supplied to adjacent unit cells flow in crossing directions to each other, crossing flows, parallel flows, opposite flows, etc., can be made for combination of flows of oxidier gas 3 and fuel gas 6, since the flow direction of fuel gas 6 is fixed. Inlets and outlets of oxidier gas 3 therefore differ in adjacent unit cells, and heat generation distribution also differs based on current density distribution. By combination of both, temp distribution can thus be uniformalized for both of the flow direction of oxidier gas 3 and the crossing direction to it, thereby the performance, service life and reliability of a fuel cell can be improved.

Abstract: PURPOSE:To convey a sheet of paper to a fixing means without its bending or curling by setting up a guide member extending over a conveying means along the conveying surface so as to make the upstream end overlap with each other above a separating means, while tilting it downward toward the downstream side. CONSTITUTION:In this conveyor, there is provided a guide member 8 extending over along a conveying surface 4C of a conveying means 4. Upstream end of the guide member 8 is pivotally supported rockably in the vertical direction so as to overlapping with each other above a separating claw 2 by a shaft 11. In addition, the guide member 8 is tilted downward as far as an angle theta with the conveying surface 4C, and an extension part 8a of the guide member 8 is made contact with a fixed part 8b so as to keep the tilt angle theta and this tilt angle theta is made rockable in a range of 0 deg.-10 deg.. Accordingly, even if a tip of paper 3 being fed after being separated by the separate claw 2 is curled, it is fed to the downstream side along the guide member 8 without getting into an interval between the claw 2 and the guide member 8, thus any possible bending or curling is kept back and simultaneously such a possibility that an adjacent part might be rubbed against the guide member 8 is thus prevented from occurring.
