Title: Method and device for detecting head speed
Inventor: SUZUKI HARUYUKI
IPC: G11B21/08
Filed: 1992-01-31
Abstract: PURPOSE:To accurately detect a speed of a head with simple constitution by multiplying a detecting speed by a period of a period signal outputted in accordance with movement of the head and comparing it with a prescribed value and then integrating a compared result so as to be as the detecting speed. CONSTITUTION:A track traversing signal TE which is detected when an optical head 2 traverses a track on a disk 1 is shaped in waveform by a comparator 3, so that a digital signal TC is obtained. Subsequently, the signal TC is detected by a period detecting means 4, so that a track traversing period signal td is generated. Then, the signal td is multiplied by a speed detecting output vd by multiplying means 5. This multiplied result is inputted to a subtracing means 6, so as to be compared with a constant. Then, a compared result is integrated by an integrating means 7 to obtain the speed detecting output vd. By such a series of feedback loop, the output vd in proportion to an inverse number of the signal td is obtained. Consequently, the head speed can accurately be detected without making an inverse calculation.

Title: Paper sheet feed roller
Inventor: HACHIMAN KICHIJI
IPC: B65H3/06
Filed: 1987-02-28
Abstract: PURPOSE:To surely separate paper sheets from each other and then to feed them by providing a motion receiving structure which varies the friction force on the peripheral surface of a roller depending upon the pressure exerted to the latter, in the roller. CONSTITUTION:A feed roller 10 pressed against paper sheets A under a pressure P is rotated to separate the sheets A from each other and then to feed them. When the contact point of the feed roller 10 comes to the point (a), a friction force is effected due to the contact pressure of the feed roller 10 and the friction between a rubber peripheral surface 12 and the sheets A. When the contact point comes to the position (b), the rubber peripheral surface 12 is deflexed and deformed due to a friction force changing structure given by a hollow section 13 so that the pressure is decreased. A small friction force is effected due to friction under the decreased pressure, and when the contact point comes to a position (c), the friction force is effected in the way similar to the case of point (a), even though the friction force is small at the point (b), the difference in friction between the sheets A becomes large so as to surely effect initial separation. When the contact point has come to the point (c), a friction force is effected so that the first and second sheets A are slipped and separated surely from each other and fed while the relative difference between the dynamic friction and the static friction is maintained.

Abstract: PURPOSE:To obtain a developing device which can return to the correct position of the design at the time of developing by shifting the sleeve position at a time of no pressure, taking into account the traveling of the developing device arising with thrusting and driving. CONSTITUTION:To have a sleeve 37 travel to a position 38c at a pressurized condition, the sleeve 38 should be in a lower position 38a at the time when there is no pressure, and when it comes into contact with a photosensitive drum 9, the sleeve is in a position 38b, and with increased pressure, the sleeve rises the distance of delta1 to the position 38c. In this way, the sleeve 38 is traveled the distance of delta1 beforehand in an opposite direction of the traveling direction, due to the abutting of the developing device with respect to the photosensitive drum 9 as a photosensitive body. Thus the sleeve 38 returns correctly to the designed position at the time of developing, eliminating inconvenience in developing by a bus line of the sleeve 38 becoming parallel with a bus line of the photosensitive body 9.
