Title: Ozonolysis device
Inventor: ITO TOSHIKAZU
IPC: B01D53/86
Filed: 1987-06-30
Abstract: PURPOSE:To prevent the deterioration of a catalyst and to promote an ozonolysis reaction by providing an UV lamp for decomposing ozone in a gas- permeable ozonolysis catalyst bed. CONSTITUTION:An axial fan 12 is operated to introduce a gaseous mixture G contg. ozone and supplied from an opening 14 through a flow straightening plate 15 into the ozonolysis catalyst bed 18, and the ozone is decomposed into oxygen by the catalyst. Since the ozone is simultaneously irradiated by the ozonolysis UV lamp 20 at this time, the ozone is also decomposed thereby. In addition, the ozonolysis UV lamp 20 produces heat, hence the mixed air and ozonolysis catalyst bed 18 around the lamp are heated, and the ozonolysis reaction is promoted. Since the catalyst is directly irradiated by the UV lamp 20 in this case, the nascent oxygen generated by the UV rays acts in reverse way to the deterioration reaction of the catalyst, and the catalyst is reactivated.

Abstract: PURPOSE:To faithfully transfer a toner image onto an image carrier with high transfer efficiency by setting inherent volume resistivity within a specific range for a transfer material carrier electrostatically attracting and maintaining a transfer material and by increasing resistivity in its moving direction in comparison with its perpendicular direction. CONSTITUTION:A toner image T corresponding to image information is formed on the surface of a drum 11, the image carrier. In the transfer part A of the drum 11, the image T comes into contact with a belt 1, the transfer material carrier electrostatically attracting and maintaining the transfer material P; a conductive elastic blade 12 impresses an electric field from the opposite side to transfer the image T thereon.

Abstract: PURPOSE:To enable the measurement of a cutting shape without demounting a workpiece from a work table and omit the time and manpower required for resetting the workpiece by providing a cut edge detecting device having a reference point and a device for displaying the current position of the aforesaid point relative to a machining start point. CONSTITUTION:After the rough machining of a workpiece 5, an electric discharge machining mode is interrupted and a wire is automatically cut and removed from a work table part 1. Then, a manual operation mode is set and X and T tables T and 8 are jogged while a microscope 11 is being viewed, thereby the reference point within a field is made to coincide with a arbitrary point on a cut edge. In this case, a value appearing on the display part of an NC device 2 corresponds to a position with a machining start point as an origin. Similarly, the value of a point adjacent to the origin is read. As a workpiece 5 is not moved at all after the rough machining thereof and the origin of the workpiece 5 agrees to the origin of a programmed shape, a portion left uncut can be easily recognized from the aforesaid read value and another value showing a position corresponding to the programmed shape.
