Title: 無線ｌａｎに対するサービス品質の管理
IPC: H04W28/14
Filed: 2004-11-03
Abstract: 無線ローカルエリアネットワークにおけるＱｏＳ（Quality of Service：サービス品質）を管理する方法は、トラフィックフローを受け取ることにより開始する（３０２）。トラフィックフローは、そのトラフィックフローのＱｏＳ要件に基づき、ＴＣ（Traffic Class：トラフィッククラス）に写像される（３０４）。ＡＣ（Access Class：アクセスクラス）（それぞれのＡＣは少なくとも１つのＴＣを含む）の送信予算が計算される（３０６）。その送信予算がトラフィックフローを支援可能か否かを計算することにより、そのトラフィックフローを許可可能か否かの判定が為される（３０８）。トラフィックフローが許可された場合には、ＴＣのパラメータが調整され、既存のトラフィックフローと新規に許可されたトラフィックフローとの間のＴＣにおける衝突が処理される（３１４）。

Filed: 2007-01-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of avoiding the deterioration of correcting accuracy of deviation in superposition of a toner image caused by backlash of a gear portion 133aY and an engaging portion 133bY in a photoreceptor gear 133Y.  <P>SOLUTION: The image forming apparatus uses the gear constituted by integrally forming the gear portion 133aY having a plurality of gear wheels formed on a rotating peripheral surface and the engaging portion 133bY engaged with the photoreceptor as the photoreceptor gear 133Y. In such an arrangement, since the gear portion 133aY having the plurality of gear wheels and the engaging portion 133bY engaged with the photoreceptor are integrally formed, the backlash of the gear portion 133aY and the engaging portion 133bY is not caused. Thus, the deterioration of the correcting accuracy of shift in the superposition caused by the backlash is avoided by avoiding non-coincidence caused by the backlash between a velocity fluctuation pattern detected based on an image for detecting velocity fluctuation and a velocity fluctuation pattern made when forming an image.  <P>COPYRIGHT: (C)2008,JPO&INPIT
