Title: Head positioning control method
Inventor: KANEKO TORU
IPC: G11B21/10
Filed: 1986-12-10
Abstract: PURPOSE:To always secure the proper head position control with high efficiency by changing the servo correction ways between a case when a head is positioned at the same track and a case when the head moves to a target track according to presence or absence of a step signal applied to the head time lapse. CONSTITUTION:A servo track is sought to read the servo information for head positioning when a head is reset to its original track and positioned at a fine track against a recording track response to the time lapse and based on the positioning information or when another recording track is sought. Then a desired track is sought and the head is positioned at the fine track position of said track based on the servo information. When an information recording disk device is operated, the servo correction is carried out by the time control performed in consideration of the thermal off-track value. Thus it is possible to perform the proper and highly efficient servo correction for each operation state by means of a servo track.

Title: Device ascending and descending stairs
Inventor: YO KOJIRO
IPC: B66B9/08
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To ensure stability and safety by mounting an energizing means which rotates so that frictional resistance may always occur between a driving roller and a guide rail in the travelling direction of the driving roller. SOLUTION: When a power switch is turned on in the elevating direction, the driving force of a motor 5 is transmitted to a driving roller 4 through a variable transmission 51, rotates in the UP direction, and is brought into constant contact with the lower surface of the second guide rail L2 by a coil spring 7, so that the driving force is generated by friction between them. Part of a motor fixing plate 86 rotates in the traveling (upward) direction of the roller 4 around a rotating shaft 87. When the power switch is turned off, the motor 5 stops, and a staircase elevating device continues to stop by the frictional force of the respective rollers. When the power switch is turned on so as to lower, the driving force rotates in the DW direction according to the same steps as for UP direction to lower gradually.  At this time, the motor part fixing plate 86 rotates in the traveling direction (downward) of the roller 4.

Title: Focus detector for electron beam imaging device
Inventor: HORI AKIO
IPC: H01J37/21
Filed: 1986-12-09
Abstract: PURPOSE:To perform focusing speedily, by making a usual scanning mode and a side slipping scanning mode selectable to each other. CONSTITUTION:At a usual sample image observation mode, a bias current to be inputted into an adding circuit U is zero so that usual scanning takes place. When an operator sets it to a focus detecting mode, a control circuit outputs bias current data to be given to each exciting current of deflecting coils D1 and D2, and these data are inputted into the circuit U via a digital-to- analog converter. In the space between both, there is a gate G which is opened at every other period of scanning in the X direction. Therefore, this X direction scanning alternately performs the usual scanning and side slipping scanning, where an electron beam is not passed through the center of an objective lens L, at each piece of scanning lines. Accordingly, double images slipped in the X direction of a sample surface are formed at both surfaces of a cathode-ray tube. At this time if the operator operates a Z direction fine adjuster Z of a sample S so as to make these double images accord with each other, focusing is all over.

Title: Paper feeding roller
Inventor: KARUBE YOSHIYUKI
IPC: B41J13/076
Filed: 1990-10-30
Abstract: PURPOSE:To increase frictional power with a small pressure power of a roller for separating and feeding a cut paper sheet on a tray by linking a cylindrical elastic outer wall part to a rotational shaft through an elastic member whose elasticity is lower than that of the outer wall part, and which is elastically deformed in such a way that the outer wall part becomes a flat contact surface through the contact pressure between the outer wall part and the cut paper sheet. CONSTITUTION:A feeding roller 12 is composed of an elastic outer wall part 31, which has an uneven surface, and which comes into contact with a cut paper sheet P, and of an elastic holding part 33, which is weaker in elasticity than the outer wall part 31, and which connects the outer wall part 31 to a rotational shaft 32. The holding part 33 is composed of a plate body 33b arranged radially. The outer wall part 31 and the plate body 33b are molded into one plate by a rubber material in common. In this structure, since a space is formed between the holding part 33 and each plate body 33, the elasticity of the holding part is very low compared with the outer wall part 31. The outer wall part 31 is thus deformed into flat surface by the contact with the cut paper sheet P, and its contact area is increased and its frictional power is also increased, and the feeding performance is thus improved.

Abstract: PURPOSE:To obtain high orientation by a method wherein magnet powder of six poles or more is formed within the generation time of pulse magnetic-field, sintered and heat-treated, and its side exterior is made in the form of a true circle. CONSTITUTION:Magnetic powder is oriented in the radial directions of six poles or more in a pulse magnetic-field. The molded body obtained by completing molding within pulse magnetic-field generation time is sintered and the sintered body is heat-treated. That is, pulse magnetic-fields are generated by using the discharge of a capacitor and press molding is performed with press pressure within a short time period during the generation of the magnetic-field. A metallic mold is one in which a metallic mold sleeve (non-magnetic ultrahard sleeve) 12 is shrinkage-fitted in a pure iron yoke 10 and is made in one piece. The void 14 of the metallic mold is filled with rare earth magnet powder and they are oriented in the direction of the poles by pulse magnetic-field. In this case, because the shrinkage in the direction of magnetization is larger, irregularities occur in the side. Therefore, it is polished by a polisher and made in the form of a true circle.
