Title: Unnecessary radiation preventing device
Inventor: SAKANE TOSHIHIKO
IPC: H01J29/76
Filed: 1985-10-17
Abstract: PURPOSE:To obtain an unnecessary radiation preventing deice to be constructed with low cost without limitation on the structural design by insertion connecting an auxiliary coil in series or parallel with a horizontal deflection coil constituting a deflection yoke thereby suppressing an unnecessary signal. CONSTITUTION:Upon supply of scanning current to a horizontal deflection coil 1b and an auxiliary coil 10 connected in series, magnetic field in predetermined direction is produced as an effective field in the inner space of core at the linear section in the core 1a. Meanwhile, the leak field 6 around the bridged sections of the coils outside of the core 1a radiates externally. Upper and lower coils in the auxiliary coil 10 are wound to produce magnetic fields in reverse direction from the field of the deflection coil 1b, thus to cancel the leakage field. Since the auxiliary coil 10 is fixed to the outside of the deflection coil 1, the spatial field surrounded by the core 1a is scarcely influenced by the core 1a nor subjected to the leak field 11 at the linear section because the number of turn of the auxiliary coil 10 is considerably lower than that of the horizontal deflection coil 1b resulting in considerable reduction of the unnecessary signal level to the external space.

Title: Production of base for planographic plate
Inventor: SAKAKI HIROKAZU
IPC: B41N3/03
Filed: 1986-09-30
Abstract: PURPOSE:To produce a base for a planographic plate excellent in handleability, wettability by water and properties for electrolytic graining, by subjecting a base made of an aluminum alloy containing specified constituents in a chloride ion-containing electrolytic liquid by passing an AC current to grain the surface of the base, and then anodizing the surface. CONSTITUTION:An aluminum alloy contains 0.45-1.5wt% of magnesium, 0.05-0.5wt% of silicon and 0.05-0.7wt% of iron, the balance being aluminum and impurities. An aluminum alloy base 0.1-0.5mm thick is formed through rolling, annealing or the like, and after the surface of the base is cleaned, it is subjected to electrolytic graining. An electrolytic liquid to be used contains chloride ions in a concentration of 0.01-3%, and an AC current is passed with a current density of 5-100A/dm<2> for 10-300sec. The surface roughness of the base is controlled to 0.3-0.8mum by regulating the quantity of electricity. If the surface roughness exceeds 0.8mum, large bits are formed in the grained surface, resulting in surface smearing. If the surface roughness is less than 0.3mum, filling up of halftone dot areas of shadow areas is liable to occur, so that a favorable printed matter can not be obtained.

Title: Vessel
Inventor: FUKUZAKI HIDEKI
IPC: A61B5/20
Filed: 1992-08-06
Abstract: PURPOSE:To obtain a vessel which does not allow the content to leak out at the time of use and is dissolved or dispersed in water after the use, by a method wherein an inner sheet taking a longer time for dissolution or dispersion in water than an outer sheet is provided inside the outer sheet being excellent in water-solubility or water-dispersibility. CONSTITUTION:A vessel 1 for examination of urine has a pair of side wall parts 2 and a bottom wall part 3 provided between the lower end parts of the side wall parts, and an inspecting part 6 is provided on the inner surface of one of the side wall parts 2. A sheet material has a double structure of an outer sheet part 15 having a shape-maintaining prperty and water-solubility or water-dispersibility and a thin-film- shaped inner sheet part 16 taking a longer time for dissolution or dispersion in water than the above. At the time of use, a prescribed shape is maintained by the shape- maintaining property of the outer sheet part 15, while the inner sheet part 16 obstructs penetration of the content into the outer sheet part 15. When the vessel is put in water after the use, the outer sheet part 15 is dissolved or dispersed quickly by the water and the shape of the vessel is lost. Since the inner sheet part 16 is shaped in a thin film, the vessel is dissolved or dispersed when the shape-maintaining property of the outer sheet part 15 vanishes.
