Title: Method and device for bearing in slide bearing
Inventor: SASAKI SHINYA
IPC: F16C33/12
Filed: 1986-10-01
Abstract: PURPOSE:To lubricate and cool a hot section effectively, by forming a sliding surface of a bearing and a rotating shaft, of ceramic material or heat resisting/ corrosion resisting metal, and lubricating the sliding surface with vapor simplex or complex of vapor and water. CONSTITUTION:During high-speed-rotation, temperature of a sliding surface 4 of a baring main body 2 and a rotating shaft 3 becomes high. When water is fed from a water sending part 5 to this hot section, heat near the water sending part 5 is taken away, and film boiling is performed on the sliding surface 4. Then, pressure generated by this film boiling, functions as a static pressure bearing action. Vapor is discharged from a vapor exhaust part 6 to the atmosphere. Heat of the sliding surface 4 is taken away and cooling action of the whole device is also accelerated, by said film boiling. If the bearing main body 2 is formed of ceramic material, water molecule has high lubricating ability. Moreover, lubricant is not deteriorated with age, as not using oil but using water as lubricant, which is vaporized and scattered. In this way, the hot section can be lubricated and cooled effectively.

Title: Desired picture area determining method
Inventor: FUNAHASHI TAKESHI
IPC: H04N1/04
Filed: 1988-09-19
Abstract: PURPOSE:To accurately obtain a desired picture area other than a part where a radiation shielding material is recorded by checking a proportion of appearance of points where the absolute value of the differential value of the picture signal is greatly changed and determining a set of blocks, where this ratio of appearance is lower than a prescribed value, as the area. CONSTITUTION:A radiation shielding material packed area K of a radiography is recorded as a part whose density is considerably lower than that of the other part as the whole. The read picture area of this part includes much noise in comparison with the picture component by scattered radiation. Consequently, the absolute value obtained by differentiating the picture signal along plural lines on a recording medium including lines D1 to Dn traversing the radiation shielding material is remarkably large for the noise component, and many points where the absolute value of the differential value is remarkably large appear in the part where the radiation shielding material is recorded. Thus, a set of blocks other than blocks where the proportion of appearance of these points is higher than a prescribed value is regarded as the desired picture area.
