Filed: 1989-10-16
Granted: 1999-07-20
Abstract: Periodic permanent magnet structures comprise a plurality of azimuthally circumscribed sections of hollow spherical flux sources such that each flat face of said sections abuts one or more superconducting planar sheets.  The superconducting sheets act as magnetic mirrors to complete the magnetic image of the sections.          This produces a uniform high field in the central cavity(s).  Each spherical section has an axial bore hole through its magnetic poles.  The flux sources are arranged tangent to each other with the bore holes coaxially aligned to form a continuous channel through which charges particles may travel.

Title: Friction material and method of manufacturing such material
Inventor: NAKAGAWA MITSUHIKO
IPC: F16D69/02
Filed: 1990-08-31
Granted: 1997-05-20
Abstract: A friction material is so manufactured that a hygienic environment can be maintained while simultaneously reducing the brake noise without reducing the friction coefficient of the brake pads made of the present material. The friction material is granulated or agglomerated by a first binder which binds one or more inorganic substances having a plane netlike crystal structure into granules which are deformed so that the particles have a flat particle orientation in the resulting granules.  The flat particle  orientation  is  achieved  by  the  application pressure and/or heat during the formation.  The granules are then embedded in a second binder forming a fibrous matrix for forming the brake pad material.  The inorganic substance or substances forming the particles having the plane netlike crystal structure, promote a micro-separation in the friction surface in response to the application of a brake force.  The micro-separation effectively prevents brake noise.

Title: Lens edging system with programmable feed and speed control
Inventor: BYRON DAVID L
IPC: B24B49/02
Filed: 1991-02-26
Granted: 1999-05-04
Abstract: A computer numerical control machine system for edging lenses controls the rotation and displacement of a lens workpiece with respect to a edging tool in accordance with a lens shape stored in memory. The system continuously translates the lens workpiece axially across the surface of the wheel to uniformly distribute wear across the wheel surface, reducing the need to dress the edging tool. The system compares the lens size with predetermined dimensions and compensates for any difference by automatically adjusting the lens trajectory during the edging of subsequent lens workpieces, permitting the edging tool to wear down without appreciable errors in lens size. The system controls the edging tool speed, the lens rotation rate, the lens axial feed velocity and the grinding force between the lens workpiece and the wheel at each discrete point during the entire lens edging operation to optimize production while preventing overheating of the lens workpiece. The optimum values for these parameters are empirically determined in a preparatory programmed trial and error learning process of the invention.

Title: Pen operated processing system with speed-responsive switching
Inventor: TANAKA HIDEKAZU
IPC: G06F3/038
Filed: 1991-06-05
Granted: 2000-10-10
Abstract: In an information processing system in which predetermined information is processed on the basis of coordinate data x, y, the coordinate data x, y is inputted through a coordinate inputting means such as a pen and tablet arrangement. Inputted loci are detected by sequentially accepting the coordinate data x, y. The processing mode of the information processing system is switched according to the configuration of the inputted loci. By switching the processing mode in response to the configuration of the inputted loci, the operation mode can be switched. For example, by moving the pen on the tablet in a jumped or reversed direction manner, the processing mode such as storing of a window can be effected.
Patent CA-2048868-C (CA)
Title: Magnetic recording medium and information recording-reproduction method using the same
Inventor: NAKAJIMA JUNSAKU
IPC: G11B5/64
Filed: 1991-08-09
Granted: 1999-11-09
Abstract: A magnetic recording medium has a recording layer made up of a ferrimagnetic material whose compensation temperature is substantially within room temperatures, and an information recording-reproduction method uses the magnetic recording medium. During recording, while a light beam is projected on the recording layer so as to raise the temperature of a recording portion, information is recorded by applying a signal magnetic field from a magnetic head. During reproduction, while a light beam is projected on a reproducing portion of the recording layer so as to raise the temperature thereof, information is reproduced by detecting leakage flux from the reproducing portion by the magnetic head. Thus, during reproduction, no magnetic flux is generated from other portions of the recording layer not irradiated by the light beam. With the arrangement, crosstalk due to leakage flux from adjoining tracks not irradiated by the optical beam can be eliminated.      Therefore, track pitches can be made narrower so as to increase recording density of the magnetic recording medium. Further, since crosstalk from adjoining tracks is eliminated, a high S/N can be achieved.

Title: Method of estimating vehicle velocity and method of and system for controlling brakes
Inventor: SUZUKI OSAMU
IPC: B60T8/174
Filed: 1992-10-07
Granted: 1998-07-28
Abstract: A method of and an apparatus for estimating a vehicle velocity, which are suitable for use in a vehicle.  Velocities of drive wheels and follower wheels of the vehicle are determined and the fastest one of the so-determined velocities is selected.  The velocity of the vehicle is estimated based on the fastest wheel velocity thus selected.  The above respective processes are repeatedly executed at given time intervals.  Thus, when the estimated vehicle velocity is faster than each of the velocities of the follower wheels and lower than the fastest wheel velocity, the estimated vehicle velocity determined immediately before the above estimating process is set as a desired estimated vehicle velocity. Accordingly, a high-accuracy estimated vehicle velocity corresponding to an actual vehicle velocity can be obtained, thereby making it possible to control brakes and driving forces with high accuracy using the estimated vehicle velocity.
