Title: Detector using piezoelectric vibrator
Inventor: ONISHI KAZUMASA
IPC: G01C19/5614
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of the detected output by removing the leakage output by detecting the detection output with the signal of substantially the same phase as the phase of the output or of 180 degrees different phase as a reference. SOLUTION: After the detected outputs P1 , P2 from detecting electrode are detected by detectors 22a, 22b, they become DC components via LPFs 25a, 25b. Since the leakage voltages included in the outputs P1 , P2 equivalently contain positive and negative components during the period of the half period of a reference signal S1 , the leakage voltages are cancelled. The null voltages to be superposed with the outputs P1 , P2 have the same phases. Accordingly, the difference is taken by a differential amplifier 26 to cancel the null voltages of the outputs P1 , P2 to each other. The detected outputs of Coriolis force are reverse phases at the outputs P1 , P2 . It is the same phase as the signal S1 or different of phase of 180 degrees. Therefore, the difference is calculated by the amplifier 26 to add the absolute value of the DC voltage of the component of the Coriolis force.  The angular velocity is calculated by the detected component of the Coriolis force.

Title: Electrophotographic cleaning device
Inventor: ISOBE MINORU
IPC: G03G21/10
Filed: 1988-12-02
Abstract: PURPOSE:To prevent a blade from peeling and buckling locally and to obtain stable toner removal efficiency without any adjustment by providing a leaf spring which presses the blade against the surface of a photosensitive body across the tip part of a holding member to the overall length of the blade. CONSTITUTION:The blade 13 is fixed to the holding member 12 and pressed against the photosensitive body 11 by the leaf spring 14 across the holding member 12. Consequently, the blade withstands the frictional force based upon the rotation of the photosensitive body 11 and without peeling and buckling at a blade press-contacting point. Further, the leaf spring 14 is pressed to the overall length of the blade 13, so an almost uniform press-contacting force is obtained to the overall length of the blade. Stable toner removal is therefore carried out. If the holding member 12 deforms, the deformation of the holding member 12 is corrected with the press-contacting force of the leaf spring 14 because the leaf spring 14 is larger in spring constant than the holding member 12, so the nearly uniform press-contacting force is obtained to the overall length of the blade.
