摘要： A diagnostic apparatus includes a receiving unit to receive context information defining an operation of a tool of a machine, rotation information of a spindle, tool information, and a detection result of a time-varying physical quantity generated by the tool; a frequency analysis unit to frequency-analyze the detection result; a range setting unit to set a frequency range; a bandwidth setting unit to set a bandwidth of a noted frequency band in the frequency range; a band pass filter setting unit to set a band pass filter using center frequencies and the bandwidth; a feature information extraction unit to extract feature information from the detection result using the band pass filter and a frequency analysis result of the detection result; and a determining unit to determine a machining state using the feature information. The center frequencies are set using the rotation information, the tool information, and the frequency range.

摘要： A method for feeding sheet materials is disclosed, which is implemented by forwarding a plurality of sheet materials loaded on a loading plate with a rotating feeding roller toward a separation unit, for the leading edge of the sheet materials to be collided with a tapered face of taper member, and subsequently separating the uppermost of the loaded sheet materials through frictional force from the feeding roller after climbing over the taper member to be forwarded further to an image forming unit by way of a nip forming portion, while other underlying sheet materials are halted by the taper member owning to smaller frictional forces there between, thereby obviating the multiple feeding. In addition, the conditions suitable for sheet feeding can be satisfied for various sheet materials different in size and thickness by adjusting the distance between the point of contact of the uppermost sheet material with the feeding roller and that of nip formation, such that modulus values are equated to various sheet materials. As a result, considerably high sheet separation qualities are obtained obviating undue non-feeding or multiple feeding, and various kinds of sheet materials different in size, thickness and coefficient of friction, can be forwarded sheet by sheet securely to image forming unit, thereby achieving satisfactory image formation by means of image forming apparatuses incorporating the sheet feeding apparatuses disclosed herein.
摘要翻译：公开了一种用于输送片材的方法，其通过将带有旋转进给辊的装载板上的多个片材向分离单元转送，使片材的前缘与锥形面锥形构件，然后在爬过锥形构件之后通过摩擦力从馈送辊分离最上面的装载的片材，并通过夹持形成部分进一步传送到图像形成单元，而其它下面的片材停止通过锥形构件在其间具有较小的摩擦力，从而避免多次进给。此外，通过调节最上面的片材与进料辊的接触点和辊隙形成之间的距离，可以满足尺寸和厚度不同的各种片材的条件，使得模数值为相当于各种片材。结果，可以避免不适当的非进给或多次进给而产生相当高的片材分离质量，并且可以将各种不同尺寸，厚度和摩擦系数的片材片材可靠地递送到成像单元，从而实现通过结合本文公开的片材进给装置的图像形成装置来满足图像形成。
