Title: Transmitter using gallium arsenide fet with means for controlling gate bias voltage of the fet for suppressing undesired signal at a start condition of the transmitter
Inventor: KOJIMA TATSURU
IPC: H03F1/02
Filed: 1990-01-25
Granted: 1994-01-04
Abstract: Abstract of the Disclosure:          A transmitter using a gallium arsenide FET in a power amplifier and having a biassing circuit for generating a gate biassing voltage for the FET, a first power supply for supplying a first power to the biassing circuit and a second power supply for supplying a second power to the power amplifier, the second power being higher in voltage than the first power and being produced at a time delay from production of the first power at a start condition of the transmitter, wherein the first power is supplied to the biassing circuit through a first diode with a voltage drop to thereby reduce the gate biassing voltage below a normal one so that an undesired signal is suppressed at the power amplifier.  The second power is delivered to the biassing circuit through a second diode so that the biassing circuit is driven by the second power to produce the normal biassing voltage.  Although a multistage amplifier is used for signal amplification prior to the power amplifier and is supplied with a power from the second power supply, a number of stages of the multistage amplifier is not necessary to be increased for attenuating the undesired signal at the start condition because of the signal suppression of the power amplifier.

Patent CA-2016458-C (CA)
Inventor: EHRICH FREDRIC FRANKLIN
IPC: G01M1/16
Filed: 1990-05-10
Granted: 1999-12-28
Abstract: A low-speed balancing method ins provided for balancing a rotor to introduce balance corrections for reducing unbalance due to operation of the rotor at or near critical speeds without actually balancing the rotor at such critical speeds. The method is applicable for balancing a rotor in three, faun or more correction planes by utilising combinations of generic unbalance distributions of the rotor and predetermined mode shapes of the rotor at critical speeds: A simple method is presented which allows an operator using a low-speed balancing machine to determine measured corrections applicable to two plane of the rotor and then the operator effects at least a third correction to the rotor which is proportional to the first and second measured corrections and the unbalance/mode shape combustion. The operator then repeats the low-speed balancing sequence to determine final corrections at the first and second planes, which are then made for finally balancing the rotor.

Title: Slot radiator assembly with vane tuning
Inventor: KELLY KENNETH C
IPC: H01Q21/00
Filed: 1991-01-09
Granted: 1995-01-17
Abstract: An array antenna (20) that avoids the generation of grating lobes or second order beams is formed of a two-dimensional array of radiating elements (40) disposed in parallel rows (22) and parallel columns (24), each of the radiating elements being formed as slotted apertures within a top broad wall (28) of a waveguide (26).  The width of the broad wall is many times greater than the height of a sidewall (32,34) of the waveguide, the waveguide having a rectangular cross section.  A wave launcher (46) connected to a first end of the waveguide launches a higher-order mode of electromagnetic wave wherein the order of the mode is equal to the number of columns of the radiating elements.  A set of vanes (48, 48A) upstanding from a bottom wall (30) of the waveguide extend partway towards the top wall to provide values of inductance and capacitance which resonate at the resonant frequency to inhibit reflection of the electromagnetic wave from individual ones of the vanes. Each vane extends in a plane perpendicular to the sidewalls, individual planes of the vanes bisecting slots (40) of the radiating elements, the slots being arranged parallel to the sidewalls.  In each column, the locations of vanes are staggered from side to side so as to offset a path of propagation of the wave in the vicinity of the radiating element to reverse a sense of coupling of electromagnetic power from the wave to the radiating element.  This produces a uniform phase front from radiations from all of the radiating elements.

Title: Filter press with cake removing devices

Title: Brushless dc motor
Inventor: INAJI TOSHIO
IPC: H02P6/18
Filed: 1991-07-03
Granted: 1997-09-23
Abstract: This invention provides a brushless DC motor which does not have a position sensor for detecting a rotational point of a rotor.  Instead of using a position sensor, zero-crossing points of counter electromotive forces induced in the stator windings of the rotor are detected to obtain a pulse signal train.  From the pulse signal train thus obtained and a slant waveform signal generated in response to the pulse signal train, a position signal with a trapezoidal waveform is formed.  An electric current signal with a trapezoidal waveform is supplied to the stator windings of the rotor in response to the position signal thus formed for effecting an electric current switching of the stator windings smoothly, resulting in realizing a motor drive less in vibration and noise even when rotating at a high speed.

Title: Process for the preparation of stable, complex emulsion systems of the water-oil-type and their use as cosmetic preparations
Inventor: FERRERO LOUIS
IPC: C09K23/52
Filed: 1992-11-06
Granted: 1999-07-06
Abstract: The invention relates to a novel process for the preparation of stable complex multiple emulsions of the water-oil-water type which are well  suited for use  in cosmetic preparations. The primary emulsions of the W/O type are prepared in the presence of both a non-ionic polymeric lipophilic emulsifier and a non-ionic polymeric stabiliser each preferably having an HLB value in the range from  6  to  10.  In  a  second  process  step  more  water containing a hydrophilic emulsifier having a higher HLB value, preferably in the range from 12 to 25, is added to the primary emulsion until phase inversion occurs. It is important that the procedure in this second process step is not reversed, i.e. that the primary emulsion is not added to the aqueous phase. Further active substances, such as W filters and vitamins, may be added to the aqueous or oil phase respectively. In a third process step hydrating agents and/or gelling agents may be added, thus increasing the  viscosity  without  impairing  the  stability  of  the multiple emulsion.

Title: Continuous casting method of multi-layered slab
Inventor: ZEZE MASAFUMI
IPC: B22D11/115
Filed: 1992-04-10
Granted: 1997-02-18
Abstract: Two kinds of molten steel are poured into a mold for continuous casting.  A DC magnetic flux directed to intersect the thickness of poured contents (corresponding to the thickness of a slab) is provided when the mold is positioned at a predeter-mined height.  Molten steel is fed at positions above and below a static magnetic zone as a boundary which is formed by said DC magnetic flux and divides an inner space of the mold into top and bottom ones along the vertical direction, that is, the casting direction.  Where the difference (.DELTA.p) between the density p1 of molten steel to be fed above the static magnetic zone for form-ing the outer layer of a slab and the density p2 of molten steel to be fed below said zone for the inner layer is .DELTA.p = p1 - p2, the DC magnetic flux density (tesla) is adapted to satisfy the relations expressed by the following formulas: a) when .DELTA.p < 0, B > [2.83 x (.DELTA.p)2 + 1.68 x .DELTA.p + 0.30]; b) when 0 < .DELTA.p, B > [20.0 x (.DELTA.p)2 + 3.0 x .DELTA.p + 0.30].

Abstract: Dispositif miniature servant à déplacer un plan ou un point de référence sur un axe dans le sens de rotation ou dans les sens x-y, servant notamment au balayage par faisceau dans deux dimensions. Le dispositif se compose d'un anneau ferromagnétique entourant un noyau magnétique monté flexible et suspendu à son intérieur. Un courant électrique à différentes fréquences est appliqué à des bobines enroulées et montées à l'intérieur de l'anneau. Le noyau produit à l'intérieur de l'anneau un champ magnétique qui définit ses coordonnées par rapport à l'anneau et à ses bobines, et réagit avec le courant appliqué aux bobines pour produire un couple. La monture flexible qui suspend le noyau à l'intérieur des bobines permet le déplacement relatif entre ces éléments en réaction aux variations de courant. Le déplacement du noyau peut être utilisé pour positionner les éléments optiques. Dans un mode de réalisation, un miroir est monté sur le noyau et un faisceau laser réfléchi par le miroir produit toute une variété de motifs de balayage bidimensionnels. La forme des motifs est déterminée par la sélection des fréquences du courant appliqué aux bobines.
