Title: Measurement of characteristic vector of vibration
Inventor: SAKATA MASAYOSHI
IPC: G01M7/02
Filed: 1988-11-15
Abstract: PURPOSE:To make it possible to obtain an angular displacement component by an excitation test using only a vibration detector by differentiating the interpolation function of the displacement component of the characteristic vector of vibration which is measured at a discontinuous measuring point, and obtaining the angular displacement component. CONSTITUTION:Vibration detectors are provided at a plurality of places on a material to be measured. The interpolation curve of the maximum value of the displacement components of the characteristic vectors of the vibrations which are obtained with said vibration detectors is a continuous curve. Therefore, the displacement component at an arbitrary point is obtained as the function of the direction where the vibration detector is provided. Then, the interpolation curve for every natural frequency is differentiated, and the interpolation curve for angular displacement is prepared. The distance between measuring points is inputted on the interpolation curve of the angular displacement, and the angular displacement at the measuring point is obtained. When the angular displacement component is obtained in this way and when the data of the displacement components for about 10 points are obtained between nodes in a vibration mode, the error between the value of the angular displacement component obtained by differentiating the interpolation curve and the value of the true angular displacement component is within 2%.

Title: Transfer device and image forming device
Inventor: SHIMURA MASARU
IPC: G03G15/16
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent a transferred toner scattering phenomenon from occurring by setting the length of a transfer roller longer than the maximum paper passing width of transfer material by a specified length or longer, and setting the outside of the maximum paper passing area of the transfer roller as a non-contact part where the transfer roller does not come into contact with an image carrier. SOLUTION: The transfer roller 15 is constituted of a conductive shaft 15a functioning also as a feed electrode and an elastic layer 15b. The length of the roller 15 is set longer than the maximum paper passing width by 10mm or more, and the elastic layer 15b on the outside of the maximum paper passing area is tapered so as to make the roller 15 is non-contact with a photoreceptor being the image carrier. By setting the length of the roller 15 longer than the maximum paper passing width by 10mm or more, a current easily creeps to the end of the roller 15 and the total current of transfer is reduced, whereby a toner image on the image carrier is prevented from being scattered at the end of the roller 15.  Since the roller 15 is tapered on the outside of the maximum paper passing area so as not to come in contact with the photoreceptor, the constitution of the photoreceptor and an electrifying roller in a longitudinal direction need not be changed and cost is reduced.
