IPC: G01B21/00
Filed: 1988-04-01
Abstract: PURPOSE:To ensure a highly accurate detecting function and aim at miniaturizing a detector for a magnetic bearing by forming a tapered peripheral surface on the outer peripheral surface of a detecting ring, and by forming a detecting inner surface of the detector from a tapered peripheral surface facing the above- mentioned tapered peripheral surface.

Abstract: PROBLEM TO BE SOLVED: To lessen the liability of a carrier tape for electronic parts to damage the holding part, such as collapsing, by providing an outward projection at each of the angles of the holding part which consists of a rectangular recess to hold an electronic part in the carrier tape with feeding perforations. SOLUTION: A carrier tape 1 consists of a strip of plastic 2, such as a film of polystyrene, and has holding parts 3 and feeding perforations 4 both at regular intervals. Each of the holding parts 3 is substantially rectangular, tapers with the breadth narrowing with depth, and has along each of the four angles 5 a projection 6 jutting out outward to a height of approximately 0.1-0.3mm. This projection 6 extends along the angle 5 from end to end, forming an acute angle at the end 7, that is, an angle of a triangle in section. The projection 6 may be shaped as desired, for example, in a rectangle or in curves in section. This constitution enables preventing the holding parts from being damaged and makes it easy to pay the carrier tape off its reel.

Title: Method for suppressing stress corrosion cracking in carbon steel
Inventor: TANAKA DAISUKE
IPC: F16L58/04
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To suppress stress corrosion cracking in carbon steels by adding sulfide to an environment where CO/CO2 /H2 O are coexistent. SOLUTION: In an autoclave 10, carbon steels 1 and 1' of U-bent pieces are placed on a hanger 13 made of glass. Sulfide is added to distilled water freed from dissolved oxygen. The adding concn. of the dissolved oxygen is regulated to >=3ppm with the concn. of sulfur as the standard. CO and CO2 are introduced from a gaseous inlet 11, and a vapor phase 14 and liq. phase 15 in which CO/CO2 /H2 O are coexistent are formed in the autoclave 10. In the case the carbon steel 1 is immersed in the liq. phase and the carbon steel 1' is immersed in the vapor phase 14, the black coating of FeS is formed on the surfaces of the carbon steels 1 and 1'. Since the FeS coating has environment interrupting effect, the generation of stress corrosion cracking in the carbon steels 1 and 1' in the environment in which CO/CO2 /H2 O are coexistent is suppressed.  As the material for apparatus in chemical plants such as a synthesis gas producing plant or the like, the use of the carbon steels is made possible.

Abstract: PURPOSE:To prevent the ununiform contact of a thermal head to perform printing without irregularities by a method wherein engaging members for regulating a distance between a top plate and a platen when the top plate is closed are mounted on the top plate in the vicinity of the right and left ends of a thermal head. CONSTITUTION:With a top plate 27 opened, a thermal head 21 is pressed by a leaf spring 28 to be separated from the top plate 27 until a stopper part 29a of a guide member 29 abuts on the top surface of the top plate 27. When the top plate 27 is closed, U-shaped grooves 30a of right and left positioning plates 30 are fitted to bearings 25 for a platen 20 to position the top plate 27 in a longitudinal direction. Top end parts 31a of engaging members 31 abut on the lower surfaces of the bearings 25 to regulate the distance between the top plate 27 and the platen 20. In addition, the engaging members 31 are fitted to the bearings 25 at the top end parts 31a thereof when the top plate 27 is lowered, and engaged thereto by torsion springs 32 so as not to disengage. Therefore, even if the platen 20 is mounted on a case 23 askew, or the top plate 27 is installed askew, the both can be kept in parallel and, thus, irregularities in printing can be prevented from occurring.

Title: Method of texturing treatment on carbon substrate for magnetic disk
Inventor: MURAMATSU KAZUO
IPC: G11B5/84
Filed: 1990-03-29
Abstract: PURPOSE:To easily roughen the surface of a carbon substrate to proper roughness without roughening too much than required by heating the substrate at specified temp. in an oxidative atmosphere. CONSTITUTION:A carbon substrate for magnetic disk with the surface preliminarily polished is subjected to heat treatment at 400 - 700 deg.C in an oxidative atmosphere so as to roughen the surface of the substrate. If the heating temp. is lower than 400 deg.C it takes long time to roughen the surface of the carbon substrate, and at over 700 deg.C, the surface is apt to be too rough. By this method, carbon is changed into gas by the oxidation reaction of C + O2   CO2, which gives fine wave pattern on the polished surface. Thus, the polished surface of the carbon substrate can be properly and easily roughened without making too rough surface than required.

Fixing by gluing is performed so that the distance between the reference surface of the housing 3 and the magnetic disk receiving surface 16 of the rotor hub 1 becomes a specified value.  In this case, a low-concentration tin type or no-tin type is used as an adhesive agent. As a result, the generation of a gas containing tin is prevented, and it becomes possible to prevent a disk or polygonal mirror from blurring.
