An optical scanner is disclosed wherein coded bars are scanned by a laser beam to effect reading of a bar code of the coded bars. The optical scanner includes a rotary polygon mirror having a plurality of reflecting portions provided thereon around an axis of rotation thereof for reflecting a laser beam from a light source toward coded bars. Each reflecting portion of the rotary polygon mirror has a plurality of reflecting faces having different inclination angles from each other with respect to the axis of rotation such that an inclination angle of a line of intersection between adjacent reflecting faces of each reflecting portion with respect to the axis of rotation is different from an inclination angle of a line of intersection between adjacent reflecting faces of each of adjacent ones of the reflecting portions on the opposite sides of the reflecting portion with respect to the axis of rotation. Where the rotary polygon mirror of the construction is used, a scanning pattern which is constituted from scanning lines of various directions can be obtained from the rotary polygon mirror. The optical scanner can thus be reduced in overall size and production cost of the device.

Gesinterter Ferritmagnet und Herstellungsverfahren

Gesinterter Ferritmagnet, der durch A1-xRx(Fe12-yCoy)zO19in Bezug auf das Atomzahlverhältnis dargestellt wird. A ist mindestens ein Element, das aus einer Gruppe ausgewählt ist, die aus Sr, Ba und Pb besteht. R ist nur La oder La und mindestens ein Element, das aus der Gruppe ausgewählt ist, die aus Bi und Seltenerdelementen besteht. Die Bedingungen 0,14 ≤ x ≤ 0,22, 11,60 ≤ (12-y) × z ≤ 11,99, und 0,13 ≤ y × z ≤ 0,17 sind erfüllt. Die Bedingung 0,500 ≤ Mc ≤ 0,710 ist erfüllt, wobei Mc der CaO-Gehalt in Masse-% ist, der aus dem im gesinterten Ferritmagneten enthaltenen Ca-Gehalt berechnet wird. Die Bedingung 0,410 ≤ Ms ≤ 0,485 ist erfüllt, wobei Ms der SiO2-Gehalt in Masse-% ist, der aus dem Si-Gehalt des gesinterten Ferritmagneten berechnet wird.
