Title: Fatigue damage evaluating method for machine component
Inventor: NISHIMURA NOBUHIKO
IPC: G01N33/20
Filed: 1990-04-03
Abstract: PURPOSE:To evaluate the extent of fatigue damage from its beginning at a low cost in a short period by finding the degree of the fatigue according to the intensity distribution of reflected electrons obtained by irradiating the object polished surface of the machine component with a limited electron beam. CONSTITUTION:The surface of the material to be tested is scanned with the fast electron beam, obtained by using an X-ray microanalyzer, in two dimensions at constant time intervals and the intensity of reflected electrons obtained from respective points is detected. The detected reflected electron intensity is measured and recorded to generate the reflected electron intensity frequency distribution curve of many irradiation points. The quantitative value of the shape of these reflected electron intensity frequency distribution curve is compared with the relation between the fatigue damage of a test-piece which is given fatigue damage previously by experimentation and the quantitative value of the shape of the reflected electron intensity frequency distribution curve to evaluate the extent of the fatigue of the machine component. Thus, the fatigue extent can be evaluated from the beginning at low cost in a short period.

Title: Radiation image detector in data transfer system
Inventor: ABE KAZUNORI
IPC: G06F12/06
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To switch banks at a low cost without adding a complicated circuit in a data transfer system adopting a bank switching system. SOLUTION: The system is provided with a counter 40 for generating output data expressing the bank switching addresses A10 to A14 of a bank memory 50 on the basis of a clock CLK inputted from a main CPU 10. Output data Q1 to Q5 from the counter 40 are inputted to the upper address inputs A10 to A14 of the memory 50. The main CPU 10 sends clocks CLK corresponding to bank numbers to the counter 40. Consequently bank switching for 1K bytes can be executed only by a clock line 180 inputted to the counter 40 having simple circuit constitution.

Title: Bellows body
Inventor: TAKAGI YASUNOBU
IPC: F16J15/52
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a bellows body whose barrel is not bent easily by first shrinking at least end part on one side of the bellows body compared with a central part thereof when force is applied from both end parts of the bellows body. SOLUTION: In a first form, a height of a crown in an end part of a bellows body is higher than that of a central part thereof. In a second form, R part of a crown and/or bottom in an end part of the bellows body is smaller than that of a central part thereof. In a third form, not only R part of a crown and/or bottom in an end part of the bellows body is smaller than that of a central part thereof, but also a height of the crown in an end part of the bellows body is higher than that of the central part thereof. In a fourth form, a crown or bottom of a central part of the bellows body is a flat part without making an r part. In any form, end parts are shrunk more easily than the central part.  Since the end parts start to shrink first when pressure is applied from both ends, the bellows body becomes substantially the same as a short bellows body, and the occurrence of bending of its barrel can be suppressed.

Abstract: PURPOSE:To obtain a perpendicular magnetic recording medium having superior high density recording characteristics by traveling a polymer film along the circumferential surface of a cylindrical can under heating, dehydrating the film, cleaning the surface of the film and vapor-depositing first and second thin metallic films on the cleaned surface. CONSTITUTION:A polyimide type polymer film 16 drawn out of a feed roll 15 is traveled along the circumferential surface of a cylindrical can 20. A vacuum region is divided into a dehydration region 31, a surface cleaning region 32 and a vapor deposition region 33 with differential pressure plates 28, 29, 30. The film 16 is dehydrated in the region 31, the surface of the film 16 is cleaned by glow discharge with a glow discharger 34 in the region 32 and an underlayer of a metal such as Ti is vapor- deposited on the cleaned surface with an evaporating source 21 in the region 33. A magnetic CoCr layer is further vapor-deposited on the underlayer with an evaporating source 22. During the vapor deposition of the layers, voltage is impressed on a free roll 23 at the outlet of the can 20 to electrostatically attract the polymer film 16 to the circumferential surface of the can 20. Thus, the creasing of the film 16 in the region 33 is prevented and a magnetic recording medium having superior surface properties is produced.

Filed: 1993-04-16
Abstract: PURPOSE:To provide an elevator door device whose life as a product can be maintained over a long period of time by preventing the door from being deformed in the direction of the entrance by an external force, and preventing damage to door-mounted components, for enhancing maintenance for the door. CONSTITUTION:An elevator door 6 comprises a door hanger 5 provided with a stopper 20 which works only when an external force is exerted to receive reaction to the external force acting on the door 6, so that the reaction is received by a hanger case 1. Because the stopper 20 works only when an external force is exerted on the door 6, when the door is normally opened or closed deformation of the door is restrained without causing abnormal sounds such as the sound of contact; therefore, the equipment attached to the door can be prevented from making contact with other equipment.

Title: Manufacture of synthetic resin molding
Inventor: NISHIKAWA KAZUO
IPC: B29C33/58
Filed: 1988-04-12
Abstract: PURPOSE:To remove efficiently an internal mold release agent, by mixing an external mold release agent with said internal mold release agent and adding a fatty acid to said external mold release agent, wherein said fatty acid causes the melting point of said internal mold release agent to fall. CONSTITUTION:As an external mold release agent to be applied on the surface of mold is mixed with an internal mold release agent which is added with a fatty acid causing the melting point of said internal mold release agent to fall, this fatty acid is in contact with the surface of a molding, or a part of said fatty acid permeates into said molding and contacts to said internal mold release agent and can cause the melting point of the internal mold release agent adjuscent to the surface of said molding to fall. Therefore, in heat processing during and after molding the separating efficiency of said internal mold release agent to the surface of said molding is remarkably improved, said internal mold release agent remaining in the inside of said molding, and consequently it can be planned to shorten the heat processing time or make the heat processing temperature to fall. As in molding the separating quantity of said internal mold release agent from said molding is increased while the amount of separated internal mold release agent moving to the surface of the mold is also increased, then it is possible to reduce the internal mold release agent to be added.
