Abstract: EOUALIZING AND AMPLIFYING CIRCUIT IN AN OPTICAL           SIGNAL RECEIVING APPARATUS              ABSTRACT OF THE DISCLOSURE      Disclosed is an equalizing and amplifying circuit in an optical signal receiving apparatus comprising a preamplifier circuit (102a) having an input ter-minal (406) connected to the output of a light receiving element (101), the preamplifier circuit amplifying the electrical signal from the light receiving element to output an amplified signal, and comprising an automatic gain control circuit (103) connected to the output of said preamplifier circuit.  The preamplifier cir-cuit (102a) comprises a transistor (402) having a common-base, a current source (403) connected to the emitter of the transistor, for supplying a bias current to the transistor, and a load resistor (404) connected to the collector of the transistor.  The emitter of the transistor is connected to the input terminal (406), and the collector of the transistor is connected to the output terminal (409).  Whereby, a negative influence caused by mounting the circuit on a package can be avoided and the circuit can operate stably in a high frequency range.

Title: Improvements in or relating to the control of linear motors
Inventor: KELLY HUGH-PETER G
IPC: G01P3/52
Filed: 1990-09-05
Abstract: A linear motor comprises a stator 1 and an armature 2 provided, respectively, with a set of spaced apart permanent magnets and a set of drive coils (not shown). The permanent magnets produce a radial magnetic field whose strength varies periodically along the length of the stator 1. The field strength is to derive speed and position signals by means of detectors constituted by field coils 4 and Hall Effect sensors 10. The periodic variation of the field strength is compensated for in the case of the field coils 4 by staggering their phases along the length of the armature and selectively combining their outputs; in the case of the Hall Effect sensors, the periodical variation is used to derive positional information.

Title: Flexible high energy magnetic blend compositions based on ferrite particles in highly saturated nitrile rubber and methods of processing the same
Inventor: SRAIL RAYMOND C
IPC: H01F1/117
Filed: 1990-09-18
Abstract: ABSTRACT A flexible magnetic blend composition is pro-vided which is comprised of high energy ferrite magnetic particles in a flexible high temperature resistant and oil resistant polymer  binder.    The binder  system  is preferably a highly saturated nitrile rubber (HSN) or a polymer alloy of the same in which a HSN is the major polymer  containing  alloying  polymers  and/or additives which are compatible with processing, subsequent electron beam curing, and final product performance.   The system binder is highly loaded usually from 55 to 65 volume percent with the high energy ferrite particles,  i.e, barium and/or  strontium  ferrite  particles,  which  can produce bonded magnets with a maximum energy product of at least 1.0 megagauss-oersteds, a remenance, Br, of at least 2000 gauss, a coercive force, Hc, of at least 1800 oersteds, and an intrinsic coercivity, Hci, of at least 2000 oersteds.  The process for production of this system involves the binder system and ferrite particles being mixed,  the  ferrite particles  oriented in a preferred direction during processing,  then formed into a final geometry before being cured by high voltage electron beam radiation,  preferably in excess of  3,000,000 electron volts.  The electron beam curing in the solid state fixes dimensional stability, magnetic properties, oil, solvent, and chemical resistance of the part even when exposed to subsequent hostile temperature environments of 125°C or higher.  Any off geometry parts or trim produced in the process prior to radiation curing can be recycled through processing several times without fear of premature cure.

Title: Breathing apparatus
Inventor: KANEKO TSUNEYO
IPC: A61M16/00
Filed: 1990-10-10
Abstract: ABSTRACT     A breathing apparatus has  first bellows and second bellows,  the first bellows being so designed as to expand by a part of air exhaled by the diver or wearer of the breathing apparatus being supplied thereto through a mouth piece  and  the  second  bellows  being  so  designed  as  to contract  as  the  pressure  of  a  surrounding  atmosphere around  the  breathing  apparatus,  i.e.,  the  atmospheric pressure under water. When the sum of an expanded amount of the first bellows and a contracted amount of the second means reaches a value which is equal to or larger than a predetermined value, an exhalation discharge valve disposed on a mouth piece is so opened as to discharge the exhaled air  into  a  surrounding  atmosphere  around  the  breathing apparatus.  This  arrangement  for  the  breathing  apparatus enables the number of times of re-utilizing the exhaled air as air for inhalation to increase as the pressure of the surrounding atmosphere increases.
