Filed: 1987-04-15
Abstract: PURPOSE:To decide a moving direction by providing a grating array which generate the quantity of light asymmetrical about an axis perpendicular to the moving direction on a movable plate and detecting the state of the quantity of light which varies in time series according to the moving direction of the moving plate. CONSTITUTION:Elements 5a-5c in the grating array 5 on the movable plate 3 have mutually different shapes and are asymmetrical about the axis perpendicular to the moving direction of the movable plate. Light from a light source 1 is incident on the grating array 5 through a fixed slit 2. The light when incident on an area 5a is all transmitted, but when the light is incident on an area 5b, half of it is transmitted and when the light is incident on an area 5c, all of the light is cut off. A photodetection part 4 detects the light which is varied in quantity by the grating 5 and converts variation in the quantity of light into an electric signal, so that the moving direction of the movable plate an be decided from the time-series variation state of the signal.

Abstract: PURPOSE:To recover residual toner peeled with a blade by providing the image forming device with an image forming body, a cleaning member, and a sucking means which forms an air flow according to the operation condition of the cleaning member. CONSTITUTION:The periphery of the image forming body 30 turns clockwise, and residual toner is peeled by the press-contact of the leading edge of the blade 41; air in the upper part of a housing 40A, which is partitioned by the blade 41 and a sponge 42, is introduced into a duct 43 by an air flow, shown by an arrow A, which moves from the left to the right by means of the suction force of a fan 44 at the same time starting to turn the blade 41. As it does so, toner suspended and scattered in the air is sucked together with air; and only the residual toner is blocked by a filter 45, and falls on the toner carrying tube 71 at the bottom of the housing 40A to be recovered. Even after the press-contact of the blade 41 is released, the fan 44 rotates for the prescribed length of time; in addition to the air flow A, a vertical air flow B is formed by sucking air in the lower part of the housing 40A opened by the retreat of the blade.

Title: Unbalance correction for high-speed revolving rotor
Inventor: KOI RYOJI
IPC: F01D5/10
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To easily carry out the unbalance correction for a high-speed revolving rotor in consideration of the deflection of the rotor during its high speed revolution. SOLUTION: Vibration vectors of a rotor 1, while the rotor 1 revolves both at a low speed and at a high speed are measured by means of vibration detectors 3A, 3B and a pulse detector 4. As for the measured vibration vectors, they undergo linear transformation, based on the previously obtained linear relationship between change vectors of unbalance vectors and those of vibration vectors in correcting surfaces 1a to 1d. Thus, by computing the change vector of an unbalance vector, which is necessary to decrease the measured vibration vector down to a zero vector, as an unbalance vector, correcting details in consideration of the deflection of the rotor 1 during its high speed revolution can be determined by only measurement of the vibration vectors carried out prior to the correction of the rotor 1.
