Title: Method, device and system for reading image and storage medium
Inventor: NAGASE TETSUYA
IPC: H04N1/407
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To provide an image reader with which image information for all over the satisfactory original is read. SOLUTION: A correcting means 33 corrects the image information at a part, where the quantity of illumination light is fluctuated, in the image information over all the original read by scanning the illuminated original. Thus, concerning a copying machine or the like with which the original is conveyed to a prescribed position on platen glass by a conveyer belt and that original is illuminated through the platen glass, the quantity of illumination light is lowered at an original floating part caused by the separation of the conveyer belt from the platen glass so that the base is covered by the read image information or the like but the image information at such a part can be corrected.

Title: Scutcher machine
Inventor: KOSHIYAMA HIROYUKI
IPC: D06C3/08
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To provide a scutcher machine capable of preventing detection failure caused by the difference of the kind of a rope-like web and expanding a rope- like web passage zone in good operability by disposing a switching mechanism for expanding the web passage zone on a torsion-detecting device. SOLUTION: In this scutcher machine, a rope-like web 13 is fed into a torsion- detecting device 1 which can expand a web passage zone formed between a detection plate 3 and a pressure detection plate 5 with a switching mechanism 2 comprising the pressure detection plate 5, a spring 6, a sliding shaft 7, a bracket 8 and an air cylinder 9. The torsion of the web 13 is detected as the displacement of the torsion detection plate 3, and a contactless switch in a sensor box 11 detects and subsequently outputs a torsion detection signal to a torsion-correcting device on the upstream side to correct the torsion. A remote control device is operated in dependence to the kind of the web to operate the air cylinder 9. The web passage zone is thus expanded into a passage zone size suitable for the web to prevent the failure of the detection.

Title: Magnetic head
Inventor: KIMURA AKIRA
IPC: G11B5/265
Filed: 1988-12-20
Abstract: PURPOSE:To obtain the magnetic head which can deal with a tendency toward higher recording densities without allowing the part of a spacer material to generate the effect of a pseudo gap by adopting the constitution in which the opposite surfaces of a core for recording and reproducing and a core for erasing are joined via the spacer material with a certain angle provided with the gap for recording and reproducing on the sliding surface of the cores. CONSTITUTION:The opposite surfaces of the core 11 for recording and reproducing and the core 12 for erasing are joined via the spacer material 16 with the angle provided with the gap 13 for recording and reproducing. The angle of the core joint part via this spacer material 16 is merely required to be adjusted to attain the optimum angle by the two conditions; the distance t between the gap for recording and reproducing and the gap for erasing and the azimuth loss quantity of the part of the spacer material 16 indicating the pseudo gap effect. The joint part via the spacer material 16 is prevented by the azimuth loss of the gap from exhibiting the pseudo gap effect in this way. The deterioration in the recording and reproducing characteristics of the magnetic head is thus obviated and the magnetic head which can deal with the high-density recording is obtd.

Title: Double sided magnetic recording and reproducing device
Inventor: ISHIKAWA HIROYUKI
IPC: G11B17/32
Filed: 1990-11-27
Abstract: PURPOSE:To decrease the burden of a magnetic sheet and to stabilize rotation and head touch by forming the inclined flat surfaces of magnetic heads on both surfaces of the magnetic sheet to a specific shape and area and disposing these heads in the positions shifted along the rotating direction of the sheet. CONSTITUTION:Both upper and lower magnetic heads 1, 2 are disposed in the positions shifted to the extent of preventing the overlap thereof in the rotating direction R of the magnetic sheet 3. The positional relations of the flat surfaces 4, 5 and the free rotating surface N are maintained constant. The magnetic heads execute recording and reproducing in the state where the heads are brought into sliding contact with the sheet by the negative pressure generated by the rotation of the sheet. The abrasion loss by the amount of the negative pressure to be generated and the sliding quantity of the sheet varies with the shapes of the flat surfaces 4, 5. Then, the radial length of the sheet of the flat surfaces is specified to >=0.8mm and the circumferential length to >=0.5mm and the area is specified to <=12mm<2>, by which the optimum negative pressure is attained and the load of the sheet is decreased. The rotation and head touch are thus stabilized.

Title: Method for polarizing piezoelectric ceramic
Inventor: DOMON TAKAAKI
IPC: H01L41/257
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To evenly polarize a piezoelectric ceramic by polarizing the ceramic to a polarized state, which does not reach a desired polarized state in the air in an initial polarization treating process and polarizing the ceramic to the desired polarized state in the air in an additional polarization treating process. SOLUTION: In the initial polarization treating process by means of an initial polarization treating device 1, a piezoelectric ceramic substrate 3 is polarized to a polarized state which does not reach a desired polarized state. After the initial polarization treating process, the substrate 3 is brought to an additional polarization treating process 2, in which the substrate 3 is polarized to the desired polarized state. Since the substrate 3 brought to the process 2 is treated through the initial polarization treating process, only an additional polarization is performed on the substrate 3 so as to polarize the substrate 3 to the desired state from the initially polarized state. Since the substrate 3 is polarized in two stages in this way, the ceramic can be polarized evenly and sufficiently.
