Title: Method of manufacturing and applying heat treatment to a magnetic core
Inventor: TAKEUCHI MASATO
IPC: H01F41/02
Filed: 1992-03-04
Granted: 1998-08-18
Abstract: A magnetic core having a low core loss and having stable characteristics in a low magnetic permeability region can be obtained at a high yield by applying a heat treatment to a magnetic core main body obtained by winding or laminating a ferrous amorphous ribbon in a wet atmosphere containing a limited amount of steam.  Further, a magnetic core having stable characteristics for the quality of products can always be obtained at a high yield even when magnetic ribbons as the blank have scattering, by adopting a method of applying a heat treatment to the magnetic core main body as described above by measuring the curie point, the differentiated crystallization temperature or the crystallization temperature of optionally sampled amorphous ribbons and comparing the measured value for the temperature with the curie point corresponding to the heat treatment temperature for the previously prepared aimed magnetic permeability, the differentiated crystallization temperature or the crystallization peak temperature, thereby determining an optimum value for the heat treatment temperature.

Title: Adaptive feed-forward method and apparatus for amplifier noise reduction
Inventor: TALWAR ASHOK KUMAR
IPC: H03F1/32
Filed: 1992-11-23
Granted: 1998-01-20
Abstract: An adaptive feed-forward cancelling system obtains a reference signal and a sample signal from an amplifier by directional couplers.  The sample signal essentially consists of an undistorted input signal component and a noise and distortion component.  The reference and sample signals are provided to an adaptive interference canceller which performs an adaptive cancellation process.  The interference canceller provides a cancellation signal essentially consisting of the signal component which is common to both the reference signal and the sample signal.  The cancellation signal is injected into a transmission line which carries the sample signal so that only an error signal remains which essentially consists of the noise distortion component of the amplifier output signal. the error signal is then amplitude and phase adjusted to have substantially the same amplitude and to be substantially 180° out of phase with the amplifier output signal.  The amplitude and phase adjustment error signal is then injected by a directional coupler onto the transmission line which carries the amplifier output signal so that an amplified input signal is provided by the power amplifier without the noise and distortion components added by the amplifier.

Title: Method for controlling movement of neutral atom and apparatus for carrying out the same
Inventor: OHTSU MOTOICHI
IPC: H01S3/00
Filed: 1993-02-26
Granted: 2001-05-29
Abstract: In order to control the movement of a single neutral atom or a small number of neutral atoms to trap the neutral atom or atoms at a distal end of an optical fiber probe, a laser light having a light frequency which is slightly lower than a resonance frequency of the atom is made incident upon a proximal end of the optical fiber probe and an evanescent light is generated from a sharpened distal end of the optical fiber probe whose tip is sharpened such that a radius of curvature is smaller than one wavelength of the laser light.      The distal end of the optical fiber probe is brought close to the neutral atom or atoms to trap the neutral atom or atoms within an existing volume of the evanescent light. When the light frequency is changed to a value slightly higher than the resonance frequency of the atom, the trapped neutral atom or atoms are pushed out of the existing volume of the evanescent light. The crystal growth can be performed with a single atom level.

Granted: 1999-05-04
Abstract: A multiplexer, preferably on an integrated circuit chip, receives a plurality of buses each having a plurality of lines responsive to binary indications and passes the binary indications in the lines of a particular one of the buses.          The multiplexer includes a plurality of circuit blocks each responsive to the binary indications in the lines of an individual one of the buses.  Each block has a plurality of recursive circuits each having first and second stages.  The second stages of the recursive circuits in an individual one of the circuit blocks receive an individual one of a plurality of control indications at a first side of the block to activate the first stages in such recursive circuits.  The first stage in each recursive circuit in each individual circuit block receives at a second side of the block the binary indications in an individual line in an individual one of the buses to obtain a signal from such first stage in accordance with such binary indication upon the activation of such first stage.  The output lines of the same binary significance in the different circuit blocks are connected in an OR relationship.  Each output circuit in a plurality is responsive to the signals in the OR relationship of an individual binary significance from the recursive circuit in the activated block to provide output signals from the multiplexer.  The multiplexer accordingly provides a recursive and expansible arrangement for passing signals at each instant from a selected bus without any wire crossovers.

Abstract: There is shown a hydraulic telescoping ram of the type suit-able to tip dump trucks and the like, which permits the use of outer aggressive seals and a bore sealing device by providing a conduit which hydraulically connects the upper end of each cylinder of the telescopic ram with an oil reservoir. This makes it possible to use seals which are not aggressive and which can run on surfaces of somewhat less than top quality, on the internal bottom faces of the rams so as to allow the passage of a small quantity of oil into a gap formed within the ram and cylinder and between the aggressive and non-aggressive seals. The oil which passes the non-aggressive seal is returned to the oil reservoir when the ram is extended.
