Title: Surface treatment of stainless steel
Inventor: MIYAKE AKIKO
IPC: C23C8/18
Filed: 1994-03-30
Abstract: PURPOSE:To minimize the amt. of metallic ions leached from the surface of a stainless steel member by cleaning the surface of the member, forming an oxidized coating film on the cleaned surface by heating in a gaseous oxygen- nitrogen mixture under specified conditions, dissolving and removing the coating film. CONSTITUTION:The surface of a stainless steel member is perfectly cleaned with an acid and ultrapure water after electropolishing and ultrasonic cleaning. The member is baked at 150 deg.C for 1.5hr in a gaseous N2-O2 mixture consisting of 80% N2 and 20% O2 and having <=-40 deg.C dew point and it is further heated at 415 deg.C for 2hr to form an oxidized coating film on the surface of the member. The coating film is then dissolved and removed by immersion in 0.1N hydrochloric acid for about 30min and the member is finally washed and dried. By this surface treatment, the amt. of ions of metals such as Fe, Cr, Ni and Mn leached from the surface of the stainless steel member is extremely reduced and the member is used as a superior stainless steel member in a field requiring no leaching of metallic ions.

Abstract: PURPOSE: To provide a subject system which permits the use of an inexpensive pulse motor with a comparatively low processing precision, by a format wherein a printing instruction signal can be generated on the basis of the maximum value of hunting vibration.  
     CONSTITUTION: A time t 0 , required for the duration of the movement of a motor 7 from a point of time of, say, X 1 , which is the maximum value of vibration of a hunting phenomenon in a linear pulse motor, to a point of time when the motor firstly passes through a final stopping position (stabilizing point), is obtained by t 0 =T/4=π/2(M/K) 1/2  presuming that a vibration cycle is T, (where K is a tilt constant of a thrust curve; M is weight of a moving part). The tilt constant K can be changed by varying a current value of, e.g. a drive coil. A drive current value is selected so that a time t h , required for the duration of the movement of a printing hammer 6 from a point of time when a printing instruction signal is generated to a point of time when the hammer reaches above a platen 1, can become equal to T 0 . This causes a horizontal aligment to be held precisely.

IPC: G01N27/409
Filed: 1990-03-15
Abstract: PURPOSE:To prevent dispersion in air fuel ratio due to formation of oxide films and the deterioration of a platinum catalyst layer by melting and removing the oxide films formed on the surfaces of an electrode in baking of platinum electrodes with hydrofluoric acid, and thereafter forming the platinum catalyst layer. CONSTITUTION:Platinum paste is applied on the parts of the inner and outer surfaces of a damp-dry ceramic tube 1 whose main component is ziroconium oxide. Thereafter, the tube is baked at specified high temperature. At this time, platinum electrodes 2 and 3 for taking out electromotive force are formed at the platinum-paste applied part. Oxide films 4 are formed on the surfaces. Then, the surfaces of the platinum electrodes 2 and 3 are immersed into hydrofluoric acid 11 so as to melt and remove the oxide films 4. Then, a platinum catalyst layer 5 is formed by vapor deposition, sputtering, plating or the like of the platinum of the outer surface. A protecting layer 6 is formed by thermal spraying of oxide metal such as magnesium spinel from the upper side. Thus the oxide film 4 is removed, and catalyst oxidizing function is enhanced. The controlled air fuel ratio is made rich. Therefore, the controlled air fuel ratio can be kept in the vicinity of a theoritical air fuel ratio without dispersion.
