Title: Measuring method and apparatus of distribution of clogging in inner face of tube
Inventor: TSUCHIYA KENICHIRO
IPC: G01B15/00
Filed: 1991-05-20
Abstract: PURPOSE:To quantitatively detect the clogging state of the inner face of a tube and to correctly measure the position of the clogging part. CONSTITUTION:A tube 1 is disposed between a radiation source 2 and a radiation measuring device 3. The distribution of the transmittance is measured as the radiation source and the measuring device 3 are moved in directions orthogonal to each other. The distribution of the transmittance measured in every orthogonal direction is compared with an expected transmittance expected from the diameter, thickness and contents of the tube by means of a clogging ratio distribution calculating means 15. As a result, the distribution of the clogging ratio is operated for every orthogonal direction. The distribution of the clogging ratio in every orthogonal direction is synthesized by a synthesizing means 16, whereby an image signal representing the distribution of the actual clogging state is formed and displayed.

Title: Additive for molten aluminum alloy
Inventor: MORITA SHIGETAKA
IPC: C22C14/00
Filed: 1994-06-24
Abstract: PURPOSE:To obtain an additive for a molten Al alloy for producing defectless Al alloy castings and die castings having excellent airtightness by incorporating a specific amt. of hydrogen into a metals or alloy. CONSTITUTION:This additive for the molten Al alloy is obtd. by incorporating <=0.05wt.% H to the metal or alloy, more preferably Ti, Zr or their alloy and further, incorporating <=1% metal hydride, more preferably Ti or Zr hydride thereto at need. The additive is preferably used in the form of a compression molding or in the form of sealing the additive into an Al vessel in a reduced pressure atmosphere and or inert gaseous atmosphere. The H is added to the Al alloy without oxidizing the alloy by using such additive, by which occurrence of casting defects, such as shrinks, of the thick parts is obviated and the connection of pores to each other is prevented by dispersing the pores. The excellent castings and die castings are thus obtd.

Title: Manufacture of flexible magnetic recording body
Inventor: TAGAMI MASAMICHI
IPC: C08L79/08
Filed: 1983-08-04
Abstract: PURPOSE:To obtain a recording body having negligible crack and curl and superior high-density characteristics by specifying the internal stress of a continuous thin film of magnetic iron oxide contg. Fe3O4 contg. optionally additives as the principal component during formation. CONSTITUTION:A magnetic film is formed on a polyimide substrate of 12.5mum thickness as a long-sized flexible substrate in a planar magnetron sputtering apparatus using Fe3O4 contg. 5wt% Co and 4wt% Cu as a target. A substrate sending and coiling mechanism is placed in the sputtering apparatus, and the long-sized substrate is sent along a water-cooled cylindrical cooling can to form continuously a magnetic film. A magnetic film having no internal stress (1<PAr <3X10<-3>Torr) does not cause crack and curl in a wide temp. range up to a temp. at which the thermal shrinkage of the substrate becomes remarkable, and it has superior flatness and surface properties. When the internal stress sigma is in the range of -3X10<9>dyne/cm<2> <sigma<2X10<9>dyne/cm<2>, curl is slightly caused, yet it is allowable in practical use.

Title: Method of cutting silver halide photographic sensitive material
Inventor: HATTORI KAORU
IPC: G03C1/00
Filed: 1988-06-09
Abstract: PURPOSE:To prevent the generation of pressure fogging by applying cutters to the photosensitive material from the surface opposite to the surface having silver halide photographic emulsions, thereby cutting the material. CONSTITUTION:A factory-wound roll 1 is the photosensitive material wound to a roll form and is usually positioned with the silver halide emulsion surface on the inner side. The photosensitive material is sent through a photosensitive material route 2 or 2' to a slitter section 4 via a tension adjusting roller 3. The upper cutter blades 5 and the lower cutter blades 6 are respectively formed as rollers in the slitter section 4 and the factory-wound photosensitive material is passed between the same, by which the photosensitive material is slit to a prescribed width. The silver halide surface side of the photosensitive material faces the upper cutter blades 6 in the route 2 and the opposite side thereof faces the blades in the route 2'. The route 2' where the surface opposite to the emulsion surface faces the cutters is, therefore, adopted in this invention. The pressure fogging is prevented in such a manner.
