Title: Density measurement device for printed matter
Inventor: KIMURA TAKAYUKI
IPC: B41F31/02
Filed: 1990-09-07
Abstract: PURPOSE:To make it possible to measure instantaneously density information on measurement points in a single sheet of printed matter by arranging density measurement sensors freely at positions corresponding to density control charts and providing a lift device which allows the density measurement sensors to come in contact with the surface of printed matter. CONSTITUTION:Printed matter is sucked by a suction orifice 27 of an adsorption device 26 from below measurement spots. Then any number of density setting sensors 23 are allowed to descend simultaneously using a lifting device until their sensor heads come in contact with the surface of printed matter so that an outer light does not enter the sensors. Light is emitted to the printing surface shielded from alight source in the sensor 23. A reflective light is condensed to a one spot using an optical fiber and then is converted to a voltage by a photo-electric sensor after passing through various color filters. The voltage thus converted is converted to a density value by a specified circuit which is a circuit for analyzing density information. Any number of density values thus converted is graphed to provide an operator with current print information.

Title: Reduction roasting method of iron and steel dust
Inventor: YASUKAWA MOTOHIRO
IPC: C22B13/02
Filed: 1983-12-16
Abstract: PURPOSE:To increase the rate of evaporating and recovering Zn and Pb and to decrease the content of F in the recovered crude ZnO by adding a CaO source to iron and steel dust and increasing the CaO/SiO2 ratio of the charge in a rotary kiln thereby enabling a long-term continuous operation. CONSTITUTION:Iron and steel dust contg. Zn and Pb and a carbonaceous reducing agent are charged into a rotary kiln. The inside of said kiln is heated by the burner at the end on the discharge side of the kiln to reduce and evaporate Zn and Pb, by which the Zn and Pb are recovered. A CaO source is added to the iron and steel dust to increase the wight ratio of CaO/SiO2 in the above-described kiln charge to 2.5. The m.p. of the material formed in the reduction process is thus increased and the material sticking on the inside wall of the kiln is made hardly formable, by which the long-term continuous operation is made possible and the rate of evaporating and recovering the Zn and Pb is increased. CaO reacts with HF to form CaF2 and the F entering the evaporated and recovered crude ZnO is decreased.

Title: Fixing device for workpiece
Inventor: MAIKERU ERU KORII
IPC: B23Q3/154
Filed: 1988-09-22
Abstract: PURPOSE: To quickly and easily fix a workpiece, and precisely hold it by constituting a fixing device for a workpiece with a base, a permanent magnet for generating the magnetic field in the base, an electromagnet which is energized to reduce the strength of the magnetic field of the permanent magnet, and a fixing plate. CONSTITUTION: When a plate 50 is first located on a base 15, an electromagnet 30 is energized to reduce the magnetic field generated by a permanent magnet to almost zero. Then, the plate 50 is lowered on the base 15, and bushings 58 in the plate are shifted to be vertically matched to bushings 57 in the base 15. Further, after dowel pins 51 are inserted into the bushings to prevent the movement of the plate 50 on the base, the electromagnet 30 is de-energized, and thus the permanent magnet 28 pulls the plate downward to locate it on the base. At this time, magnetic flux is passed between polar surfaces 31, 32, and is passed in the steel plate.  During the period of processing a workpiece, the electromagnet is de-energized, but when the processing operation of the workpiece is completed, the electromagnet is energized to weaken the magnetic field of the permanent magnet, and thus to lift the plate, a V block, and the workpiece.
