Title: Image outputting device and its control method
Inventor: KASHIWABARA ATSUSHI
IPC: H04N1/405
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To enhance the quality of an outputted image at a toner saving mode. SOLUTION: In a toner saving mode, 200 lines are selected as a pulse width modulation mode at the step S1402 and a conversion table for the toner saving mode is selected at the step S1403. The conversion table determines the conversion rule for lowering the density of an outputting image signal such as the rule for halving. After that, binary dither treatment is applied to the image signal at the step S1404 and then converted to the outputting image signal by means of the conversion table for the toner saving mode so as to form an image in the pulse width modulation mode of the 200 lines at the step S1405.

Title: Hot dip plating method for hot rolled steel sheet
Inventor: SAKURAI MICHITAKA
IPC: C23G3/02
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To reduce the production cost by integrating a descaling pickling stage in a hot rolled steel sheet into a continuous hot dip plating line and furthermore to produce a hot dip plated steel sheet excellent in plating adhesion at a low cost. SOLUTION: A hot rolled steel sheet S is subjected to descaling treatment, is thereafter treated with a pickling soln. contg. metallic ions nobler than iron and is subsequently applied with hot dip-plated of zinc or a zinc series alloy. It is preferable that the pickling soln. contg. metallic ions nobler than iron is the one contg. metallic ions of one or >= two kinds selected from Cd, Co, Ni, Sn, Pb and Cu or the pickling soln. is composed of hydrochloric acid. Since the descaling rate increases, remaining scale and remaining smuts on the surface of the steel sheet after the pickling reduce and the metallic ions nobler than iron precipitate on the surface of the steel sheet at the time of the pickling, its reactivity with the plating metal is made satisfactory, by which its adhesion improves.

Filed: 1984-07-17
Abstract: PURPOSE:To easily provide a coated pattern film of uniform high quality even on a complex curved surface having a concave curved surface, by transferring by pressing a coating liquid onto the curved surface through a screen by a deformable pressing body. CONSTITUTION:The screen 4 capable of conforming the shape of a curved surface of an article is brought into contact with the curved surface, and a coating liquid is transferred by pressing onto the curved surface through the screen 4 by the deformable pressing body 5 capable of being deformed in conformity with the curved surface, thereby providng a coated film in a predetermined pattern on the curved surface. For example, of a polycarbonate windshield, a part 3 not to be coated is masked, a screen plate 4 is brought into contact with the concave curved surface of the windshield 1, and a silicone rubber sponge pressing body 5 is pressed against the windshiled 1 along a peripheral edge part of the curved surface through the screen plate 4, whereby a coating liquid is transferred from an impregnated part 6 onto the windshield 1, thereby coating the windshield 1 with the coating liquid. Accordingly, since the pressing body is deformed in conformity with the curved surface, uniform pressing is achieved even in the case of a concave curved surface, the coated pattern film thus obtained is uniform, and the thickness of the film is also uniform.

Title: Optical pickup device
Inventor: EMOTO MASAMI
IPC: G11B7/135
Filed: 1992-05-13
Abstract: PURPOSE:To promote utilization efficiency of outgoing light from a light source and to improve a signal detecting level by leading the outgoing light with its high characteristic in a position of an optical axis and lower characteristic toward a peripheral part to a magneto-optical recording medium and making characteristics of reflected light opposite to the above characteristics. CONSTITUTION:A P-polarization laser beam is emitted from a semiconductor laser 101, and is collimated by a collimator lens 102 to be incident upon a beam splitter 103. The outgoing light has a Gaussian is highest and the lower the intensity the nearer the position approaches the peripheral part. Then, transmitted light of the splitter 103 is converged by an objective lens 104 to be projected to a magneto-optical disk 2 as a laser spot. Reflected light from the disk 2 has a P-polarization component in majority, and the light in a peripheral part of the optical axis is more reflected in quantity by the splitter 103, where the intensity is lowered in the middle part and is reaised in the peripheral part. By this method, the reflected light quantity is increased, and hence the intensity change is increased. Consequently, the utilization efficiency of the outgoing light is improved, and the detecting signal level in a photodetector part 4 is raised.
