Abstract: PURPOSE:To raise the efficiency of a reflected wave by providing a step which makes the mutual reflection wave phase the same between odd order Fresnel zones and even order Fresnel zones on a reflection plate surface. CONSTITUTION:A level difference of (lambda/4)/cos/(theta/2) is provided between first and third order Fresnel zones F1, F3 of the odd order Fresnel zones and a second order Fresnel zone F2 of the even order Fresnel zones.

Filed: 1983-11-22
Abstract: PURPOSE:To obtain bond paper for a printer or copying machine of an electrophotographic process using paper sheet improved in traveling performance by using body paper superior in curling resistance and opacity. CONSTITUTION:The body paper of bond paper contains >=10wt%, preferably >=30wt% mechanical pulp and/or used paper of the material pulp. Said mechanical pulp means ground pulp, chemiground pulp, refiner ground pulp, thermomechanical pulp, etc. When the mechanical pulp or used paper is <=10wt%, sufficient opacity is not obtained. An amt. of starch to be added in order to improve strength in sizing or size pressing is <=2g/m<2>, preferably, <=1.5g/m<2>. The starch is more hygroscopic than the pulp, and when it is added >=2.5g/m<2> like continuous buisiness forms, curling resistance is deteriorated.

Abstract: PURPOSE:To screen efficiently a ferrmagnetic material and a nonmagnetic material in the state of granule or powder with high purity by disposing apart from each other the magnetic poles of many small magnets in the circumferential and axial directions of a cylindrical case. CONSTITUTION:Magnetic poles are arranged so as to be arrayed zigzag like N, S, N as shown by the bent lines in a circumferential direction and are also arranged in such a way that the N poles or S poles line up alternately in parallel with the axial center. The group of shots forms first a bridge 7 between the magnetic poles N1 and S1 along the magnetic flux of both poles in such arrangement and when the shots group moves in an arrow K direction together with a case 3 to be next position, the direction of the magnetic flux changes and therefore the bridge 7 is broken and a fresh bridge 8 is formed between the magnetic poles N1 and S2. The shot collapsed in such a way is dispersed and when the shot moves as it is again magnetically attracted, the particles of the nonmagnetic material captured in the bridge are released and such action is repeated.
