Title: Optical scanner, scanning lens and image forming device
Inventor: ICHIKAWA JUNICHI
IPC: B41J2/44
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to constitute an optical scanner with one Fθ lens without bending the generator of the lens in spite of diagonal incident on an optical deflector. SOLUTION: The optical scanner has the deflecting means on which a luminous flux is made incident so as to incline the optical axis by a prescribed angle in a sub-scanning direction from a light source and a scanning optical system which is scanned with a light spot at an approximately equal speed and converges the incident luminous flux onto the surface to be scanned. The scanning optical system is preferably composed of one element of single lens having an aspherical surface shape. This lens refracts the luminous flux by its first refraction face in such a manner that the incident angle change in the sub-scanning direction changing according to the deflection angle decreases. The lens refracts the luminous flux by its second refraction face in such a manner that the luminous flux after the emission is emitted in a direction approximately aligned to the sub-scanning direction.  As a result, the good image forming performance is maintained on the surface to be scanned and the curving of the scanning line may be lessened in spite of the diagonal incident on one element of the scanning lens.

Abstract: PURPOSE:To be endowed with string anisotropy and to obtain a compacted magnet whose dimensional accuracy is high by a method wherein a magnetic powder obtained by crushing, in a prescribed average particle diameter, an R-TM-B-M-based alloy which has been made magnetically anisotropic and which has a prescribed average crystal particle diameter is oriented and molded in a magnetic field and, after that, the powder is pressurized while it is being heated at a prescribed temperature. CONSTITUTION:An Nd15Fe78B7 alloy is formed by high-frequency fusion; this alloy is melted and cooled rapidly in an atmosphere of Ar by using a single roll method; a flake-shaped thin piece is formed, crushed coarsely so as to be 32 meshes or lower and molded by using a metal mold; a molded substance is formed. Then, the obtained molded substance is hot- pressed; after that, it is then settled, e.g., at 700 deg.C and at a strain rate of 0.01sec<-1>. This settled specimen is crushed coarsely by using a jaw crusher; a magnetic powder within a grain-size range of 100 to 500mu is molded at room temperature in a metal mold in a magnetic field of 8KOe. In addition, this molded substance is heated in a vacuum at 650 deg.C and compacted under a pressure of 3tons/cm<2>. A density of an anisotropic compacted magnet which has been compacted is 7.45 g/cc. When an average crystal particle diameter of an R-TM-B-M-based alloy exceeds 1mum, a coercive force is lowered remarkably; when it is less than 0.01mum, the coercive force is low and a prescribed characteristic of a permanent magnet cannot be obtained.

Filed: 1990-11-02
Abstract: PURPOSE:To enable accurate seek to be performed and seek time to be reduced by obtaining servo signal after obtaining the number of corresponding compensation tracks from a memory part based on the number of tracks to be sought. CONSTITUTION:A track error signal TE for generating a servo signal SS is taken from an input part 1. The track error signal TE from the input part 1 is counted by a counter part 2 and a number TC is output. A servo signal generation part 5 reads out the number of tracks to be sought ST from a memory part 3 and then sends it to a ROM for compensation. The number of compensation tracks CT corresponding to a number ST is read out of a specified table which is memorized in a ROM 4. Then, the servo signal generation part 5 generates a servo signal SS based on the number ST, the signal TE, the number TC, and the number CT and then performs seek control. This configuration allows track errors which are generated from a mirror part, a pre-format region, etc., to be eliminated, thus achieving seek more accurately and in a short time.
