High performance integrated varactor on silicon

A new MOS varactor device is described. A bottom electrode comprises a plurality of diffusion junctions in a semiconductor substrate. The semiconductor substrate may be n-type or p-type. The diffusion junctions are arranged in a two-dimensional array. The diffusion junction may be either n-type or p-type. The diffusion junctions may be contained in a p-well or an n-well.

Das vorliegende Gebrauchsmuster stellt einen Getriebemechanismus und ein fremdkraftbetätigtes Werkzeug, das diesen aufweist, bereit. Der Getriebemechanismus umfasst ein Gehäuse, eine Getriebeeinheit, die in dem Gehäuse angeordnet ist, ein Schaltglied und einen Verriegelungsring. Zur Änderung der Drehzahl kann sich das Schaltglied axial zwischen einer verriegelten Stellung, in der es bezüglich des Gehäuses fixiert bleibt, und einer entriegelten Stellung, in der es sich mit der Getriebeeinheit drehen kann, bewegen. Das Gehäuse ist mit einem Befestigungsschlitz in einer Umfangsrichtung senkrecht zu einer Drehachse versehen, und der Verriegelungsring wird über den Befestigungsschlitz in das Gehäuse eingeführt und nicht drehbar befestigt, wobei er das Schaltglied in der verriegelten Stellung dahingehend in Eingriff nehmen kann, es zu fixieren. Gemäß der Lösung des vorliegenden Gebrauchsmusters ist das Gehäuse ein einstückiges Glied und weist also eine höhere Festigkeit auf. Die axiale Dicke des Verriegelungsrings ist gering, wodurch die axiale Abmessung des Getriebemechanismus insgesamt verkürzt wird. Die Kontaktfläche zwischen dem Verriegelungsring und einer angrenzenden Komponente in der axialen Richtung ist größer, also ist die Kontaktstärke hoch und das Positionierungsergebnis ist besser. Des Weiteren gibt es bei dem Verriegelungsring einen einfachen Herstellungsprozess, und die Anzahl an Komponenten des Getriebemechanismus ist reduziert, so dass Montageschritte vereinfacht und die Kosten reduziert werden können. The present utility model provides a gear mechanism and a power tool having the same. The gear mechanism includes a housing, a gear unit disposed in the housing, a shift member, and a lock ring. To change speed, the shift member can move axially between a locked position, in which it remains fixed with respect to the housing, and an unlocked position, in which it can rotate with the gear unit. The housing is provided with an attachment slot in a ...
