    Abstract: An inertial sensor comprising a sensing portion having a weight hung by beams extending from a frame, the weight being a movable portion. The beams include distortion portions partially arranged therein, and the distortion portions are arranged to avoid edges on which stresses applied to the beams are concentrated. Roots of the beams are not formed at right angle in connecting to the weights or the frame. The roots of the beams have wider angles. It is thus possible to dissipate areas on which stresses are concentrated and improve the impact resistance without sacrificing the sensor sensitivity. Both high sensor sensitivity and the impact resistance are obtainable in accordance with the present invention.

    Abstract: A charging device includes a charging member contactable to a member to be charged. A bias source includes an AC source and a DC source and is effective to apply a bias voltage to the charging member. The bias voltage is provided by a superposing a constant current controlled AC voltage and a constant voltage controlled DC voltage. When a DC voltage is applied between the charging member and the member to be charged, the following equation is satisfied..vertline.(applied voltage V)-(charge voltage V.sub.D of the member to be charged).vertline.=.vertline.(charge starting voltage V.sub.TH).vertline..The charge starting voltage is a DC voltage at a level which the member to be charged starts charging when only a DC voltage is applied between the member to be charged and the charging member. When the above relationship is used in the AC voltage application, the charge voltage V.sub.D oscillates in the charge region with a center of DC voltage V.sub.DC. Since the peak-to-peak voltage of the oscillating voltage required for uniform charging changes with ambient conditions, it is necessary to compensate for this change. The electric current supplied to the charging member by the oscillating component provided by the AC source is controlled to be constant. Since the charge potential of the member to be charged is determined by the DC voltage component, it is charged to a constant potential by supplying a constant DC voltage level. Therefore, the DC voltage source of the bias voltage effects a constant voltage control.

    Abstract translation: 充电装置包括可与要充电的构件接触的充电构件。 偏置源包括AC源和DC源，并且有效地向充电构件施加偏置电压。 偏置电压由叠加恒流控制的交流电压和恒定电压控制的直流电压提供。 当在充电构件和被充电构件之间施加直流电压时，满足下列等式。 /（施加电压V） - （待充电部件的充电电压VD）/ = /（充电开始电压VTH）/。 充电起始电压是在被充电部件与充电部件之间仅施加直流电压时被充电部件开始充电的水平的直流电压。 当在AC电压施加中使用上述关系时，充电电压VD在具有直流电压VDC的中心的充电区域中振荡。 由于均匀充电所需的振荡电压的峰 - 峰电压随环境条件而变化，因此有必要对此进行补偿。 通过由AC源提供的振荡部件供应给充电部件的电流被控制为恒定。 由于要充电的部件的充电电位由直流电压分量确定，所以通过提供恒定的直流电压电平将其充电到恒定电位。 因此，偏置电压的直流电压源实现恒压控制。
