Title: Image binarization system and image input device and image processor formed by using this system
Inventor: TAKAHASHI TSUGIO
IPC: G03F1/00
Filed: 1989-12-01
Abstract: PURPOSE:To suppress moire fringes and to improve image quality in binarization processing of original images in which dot images and images exclusive thereof coexist by diffusing binarization errors only to the nearby images when the dot images are decided. CONSTITUTION:The images of a medium 2 are converted to an analog signal 1 S in a photoelectric converting section 1 and are inputted to a signal normalizing section 4 after A/D conversion 3. The signal 4 S from the normalizing section 4 is subjected to simple binarization in a binarizing section 10 and is binarized by diffusing the binarization errors to the nearby picture elements in a binarizing section B 20. The result thereof is outputted to a switching output section 40. A dot detecting section 30 is inputted to the binarization signal 10A, discriminates whether the dot region or not and outputs a switching control signal 30C. The switching output section 40 selects either of the signal 10A or 20B in accordance with the signal 30C and outputs the signal 40D. Thus, the moire fringes of the dot images are suppressed and the image quality is improved.

IPC: B01J13/04
Filed: 1988-12-13
Abstract: PURPOSE:To improve wear resistance and to shorten the time for film formation by using >=2 kinds of resin particles which are different in Izod impact strength at the time of repeatedly applying impact force to a mixture composed of the core material and the resin particles to coat the surface of the core material with the resin particles. CONSTITUTION:The impact force is repeatedly applied by a dry process to the mixture formed by mixing the core material and >=2 kinds of the resin particles which are different in Izod impact strength, i.e. the mixture formed by sticking of the resin particles which are different in Izod impact strength on the core material. Namely, the resin particles sticking to the core material receive the impact force and are thereby fixed onto the core material. The resin particles having the small Izod impact strength collide against the resin particles having the large Izod impact strength while receiving the impact force. The denser resin layers are thus formed. The coating layers which are resistant to peeling and have the high film strength in spite of the execution of large-volume processing are formed. The carrier for developing electrostatic images which can shorten the time for film formation, has the excellent wear resistance and is hardly deteriorated in image quality is obtd. in this way.

Abstract: PROBLEM TO BE SOLVED: To automatically and easily bend a hull shell to a target shape without requiring experience and a special skill, moreover, without moving the hull shell. SOLUTION: The shape of a hull shell 2 to be heated subject to rough bend- working is measured, and the measured shape data of the hull shall 2 is compared with target shape data.

Filed: 1989-12-04
Abstract: PURPOSE:To smoothly slide a shelf and a frame without generation of abnormal noise by a method wherein plain gears on the right and left sides are simultaneously rotated by a driving device, which drives a gear shaft or the plain gears, to move racks up or down, and the plain gear and the racks are different in material hardness. CONSTITUTION:When a shelf 1 of a shelf device is moved up or down, a dial 6 is turned to rotate a dial shaft 7 and a driving gear 8. A driven gear 9 engaging with the driving gear 8 is turned, causing a gear shaft 4 and plain gears 5 on both sides to be rotated. At this time, although the plain gears 5 on both right and left sides are moved by a gear shaft 4 while they engage with racks 14b in sliding grooves 14a on the front side, the plain gears 5 are identically rotated as they are fixed on the gear shaft 4. As a result, the frame 2, that is, the shelf 1 is evenly moved up or down without a tilt to the right or left side. And, as the plain gears 5 and the racks 14b are made of different materials, the plain gears are smoothly moved without generation of abnormal noise during rotation because of the difference in material hardness.
