Title: Method for reproducing gradation in optical recording
Inventor: NAMIKI KAZUNORI
IPC: B41J2/52
Filed: 1992-02-14
Abstract: PURPOSE:To reproduce the picture of a halftone in multiple gradations with high resolution by exposing the picture at irradiation time in a unit shorter compared with a regular irradiation time value and recording the picture of dot % decided in accordance with a minimum recording dot. CONSTITUTION:In the case of recording the halftone with an are gradation by the light spot of the light beams the irradiation time value shortened compared with the regular irradiation time value by which the minimum recording dot is recorded is set at the time of recording in the halftone by area gradation with the light spot of an optical beam to record the picture of prescribed dot %. Thus, by comparing the data with screen pattern data for which the minimum recording dot is formed in the dot generation circuit of a raster image data generation part 15, the data are converted into picture data for which the picture at a desired recording mode can be recorded and supplied to a laser driver through a picture data synchronizing output circuit 19 through a picture storage device 17. Thus, the picture of the halftone in the multiple gradations can be reproduced at high resolution by area gradation for which an area smaller than the area of the light spot for exposure is set to be the unit.

Title: Continuous rolling method for strip
Inventor: INOUE TADAATSU
IPC: B21B37/64
Filed: 1980-05-12
Abstract: PURPOSE: To avoid a sudden change of a rolling load, tension, etc., against a sudden change of a feed-in side thickness, and to smooth a prescribed change of the run-out side thickness, by altering the mill-stiffness of a rolling stand correspondingly to the thicknesses before and after changing the thickness.  
     CONSTITUTION: A mill-stiffness controller 66 controls the alternation of the mill- stiffness using a tension bar 64 and a hydraulic screw down device 65. A thickness gauge 67 detects the thickness before and after a weld point 62 of a blank material having nonuniform thickness; from these detected thicknesses and a draft percentage commanded by a draft percentage setter 68, an arithmetic device 69 operates a mill- stiffness to be set, and inputs this value to the mill-stiffness controller 66. When the weld point 62 of a blank material having nonuniform thickness arrives at a rollig stand 63, the rolling stand 63 smoothly continues the rolling work for the following blank material 61 by the function of the preset mill-striffness. By the present method, the change of the rollig load and tension is diminished.

Title: Cartridge and case for accommodating cartridge
Inventor: IKEBE MASARU
IPC: G11B23/03
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a cartridge realizing a reduction in the possibility of detachment even if a wrong inserting direction is selected, and an accommodating case for accommodating such a cartridge. SOLUTION: When a shutter member 105 moves to a closing position, a concave portion 102c is exposed. Thus, a cartridge 110, when inserted into an accommodating case, can engage with a projection portion provided inside the accommodating case, thereby preventing the cartridge from being detached from the accommodating case. On the other hand, when the shutter member 105 moves to a release position, the concave portion 102c is covered by the shutter member 105. Thus, when an information medium is inserted into a recording/reproducing apparatus, the concave portion 102c is covered by the shutter member 105, thereby resulting in preventing a mechanism of the recording/reproducing apparatus from engaging with the concave portion 102c.
