Title: Colored microfine globular particles, method for production thereof,and uses thereof
Inventor: MORI YOSHIKUNI
IPC: C09C3/08
Filed: 1987-11-10
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE Colored  microfine  globular  particles  are produced by causing carbon black to react with a polymer capable  of  reacting  with  the  carbon  black  thereby forming a carbon black-graft polymer,  dispersing this carbon black-graft polymer in a polymerizable monomer component,   and  then  polymerizing  the  polymerizable monomer component.   These particles,  in the unmodified form,   are usable as  a toner for the development of images of static charge and, in a form incorporated in a varying  component,   are  usable  such  as  in  resin composition,    coating  composition,    thermosensitive transfer  ink  ribbon  coating  agent,   thermosensitive transfer ink,   or  bakc-coating  agent  for  magnetic recording medium.

Title: Print head gap adjustment mechansim
Inventor: GEIS DAVID G
IPC: B41J25/308
Filed: 1988-05-12
Granted: 1992-03-10
Abstract: PRINT HEAD GAP ADJUSTMENT MECHANISM     Abstract A printing gap adjustment mechanism compensates for the change in the printing gap variation caused by the relative motion between two side walls of the printer frame supporting a platen and two guide rods slidably supporting a print head. The mechanism includes a compensator rod and a pair of eccentric members rotatably mounted in a compensator plate which is pivotally mounted on one side wall of the printer frame. One end of the compensator rod is frictionally secured to the opposite side wall while the other end is rotatably supported in an opening in the other side wall and is secured to an eccentric mounted to the compensator plate. One of the guide rods supporting the print head is located near the platen and is secured between two eccentric members, one of which is rotatably mounted in the compensator plate and the other is rotatably mounted in the opposite side wall. The other guide rod is secured between the two side walls. When the printing gap becomes distorted due to relative motion between the two side walls, the mechanism senses the distortion and moves the compensator plate which in turn moves the eccentric member to which one end of the guide rod is secured a predetermined distance to restore the desired printing gap.

Title: Cardiac pacemaker with switched capacitor amplifiers
Inventor: STOTTS LAWRENCE J
IPC: A61N1/37
Filed: 1988-11-22
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE         A cardiac pacemaker has a sense amplifier responsive to signals representative of cardiac activity for passing signal components lying in a selectively variable pass band and for selectively varying the gain of the passed signal.  A pair of signal comparators constituting switched capacitor amplifiers, associated with the sense amplifier, are respon-sive to the filtered and gain adjusted signal for comparison of its magnitude to predetermined target levels for determin-ation of heart rate and the need for change of rate.  Two target levels are provided in each comparator for comparison with the level of the detected signal, by multiplexing the switched capacitors.  Another switched capacitor amplifier is used to develop a voltage reference level insensitive to temperature, supply voltage, and circuit components, for deriving the target levels for the comparison.  Still another multiplexed switched capacitor amplifier comparator is used to develop a first target level to regulate the level of the pacing stimulus, and a second target level for comparison with the supply voltage level of the pacemaker as a measure of the point at which the pacemaker requires replacement.

Filed: 1989-06-28
Granted: 1993-02-02
Abstract: POSITION SENSOR             Abstract of the Disclosure For increased sensitivity an improved position sensor includes a magnetic circuit in which the stationary portion includes a permanent magnet whose width is optimally 1.5 times the tooth pitch of the exciter portion of the sensor and the magnet face proximate the exciter includes a thin layer of ferromagnetic material over which is centered a narrow magnetic sensing element, such as a magnetoresistor. The sensing element has a width typically less than the tooth width.  The sensing clement includes a thin film of a monocrystalline semiconductive material, preferably having only a moderate bulk mobility and a larger band gap, such as indium arsenide.  Current carriers flow along the length of the thin film in a surface accumulation layer, effective to provide a significant apparent increase in mobility and conductivity of said semiconductive material, and an actual increase in magnetic sensitivity and temperature insensitivity. The flux density is typically applied by appropriate magnet thickness or choice of magnet material without the need of a flux guide.

Abstract: SYSTEM FOR READING AND WRITING INFORMATION                  Abstract of the Disclosure First binary bits are read synchronously relative to clock signals (e.g. 125 MHz) from first memory positions and second binary bits are read from, or written in, second memory positions asynchronously relative to the clock signals without affecting the reading of the first memory bits.  For synchronously reading the first bits, a plurality of channels are sequentially activated at a suitable frequency (e.g. 25 megahertz).  Information from pairs of data lines are introduced into a pair of buses at the clock frequency.  The information in the buses is sampled upon the occurrence of the first polarity in synchronizing signals having frequency (e.g. 62.5 MH3) derived from the clock signals and is prolonged and evaluated in a first pair of output lines upon the occurrence of the second polarity in the synchronizing signals.  The information being evaluated is introduced to such output lines during the occurrence of the first polarity in the synchronizing signals.          The evaluated signals on such output lines are then neutralized upon the occurrence of the first polarity in such synchronizing signals.  Similarly, the information in the buses is sampled upon the occurrence of the second polarity in the synchronizing signals and is prolonged and evaluated in a second pair of output lines upon the occurrence of the first polarity in the synchronizing signals.  The evaluated signals on all of the output lines are then processed on an exclusive basis to insure that only one of the evaluated signals can be introduced at any one time to a resultant line.                             * * * * * * * *
