Title: Phase changeable optical recording medium
Inventor: OSHIMA NORIKAZU
IPC: G11B7/243
Filed: 1990-09-05
Abstract: PURPOSE:To control crystallization time freely and increase repeatability by adding a specific amount of C or B to a phase changeable data recording film of three elements Ge-Sb-Te as a recording film. CONSTITUTION:Elements for suppressing atomic dispersion are added to a phase changeable recording material and thereby the viscosity of an amorphous substance is adjusted. Consequently, an optical disc medium is obtained which allows adjustment of a crystallization time under the form of a composition required for the enhancement of repeatability of record erasure. The candidate additive element is C or B. The recording layer 3 of a recording medium is an alloy film of Ge1Sb2Te4 to which C or B is added. An increase in a unit addition amount is more significant in C rather than B. If the addition amount is 15at% or higher, no additive effects are recognized and the value beyond that level remains almost constant. This trend is also seen in other compounds of Ge1Sb4Te7 and Ge2Sb2Te5.

Title: Motor that rotates in one direction
Inventor: YAHAGI SHINICHIRO
IPC: H02K1/14
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To enable quick rise, large torque and high-speed rotation by making asymmetric in the same direction the magnetic characteristic that each tooth has with respect to the line in the radial direction that connects the center of a circle to that of the tooth. SOLUTION: For example, a tooth of a stator 1 has an area of the left side of a symmetric line r which is wider than that on the right side, and the distance from a rotor to the outer line of the right side increases gradually. This asymmetry brings about the rotation in one direction. Specifically, the current flowing through the coil of the stator 1 forms an N pole on the left side of the tooth and an S pole on the right side. Because the force with which the N pole of the stator 1 and the S pole of the rotor 2 attract each other is larger than the force with which the S pole produced on the right side of a neighboring tooth and the S pole of the rotor 2 repel each other, the rotor 2 starts rotating always counterclockwise. The tooth of this shape can prevent the occurrence of a starting dead point. The larger the difference between the attractive force and the repulsive one is, the larger the torque of a motor is. Thus, high-speed rotation can be achieved.
