Granted: 1999-07-13
Abstract: Disclosed herein is a resin composition for toner mainly composed of a graft polymer which is formed by (a) 90 to 99.9 percent by weight of a copolymer formed by copolymerizing a styrene monomer and (meth)acrylic ester to contain at least 50 percent by weight of the styrene monomer and (b) 0.1 to 10 percent by weight of an ethylene-vinyl acetate copolymer having a saponification value of 10 to 30 and a softening point of 70 to 200°C.  This resin composition is prepared by graft-polymerizing the copolymer (a) and the ethylene-vinyl acetate copolymer (b) under presence of a peroxide polymerization initiator.  When a polyvalent metal compound (c) is employed, 85 to 99.9 percent by weight of the copolymer (a) and 0.1 to 10 percent by weight of the ethylene-vinyl acetate copolymer (b) are graft-polymerized under presence of 0.01 to 5 percent by weight of the polyvalent metal compound (c) and a peroxide polymerization initiator.

Inventor: STESSENS WERNER JOZEF CATHARIN
IPC: H03M13/35
Filed: 1993-07-13
Granted: 1998-05-19
Abstract: The error detection and correction device detects and corrects single bit errors in a sequence of bits comprising a plurality of n-bit containing subsets applied on a parallel bus IN having m subset parts.  It includes a storage module ST connected to the bus IN and which transfers the subsets as they are received on the bus to a divider logic circuit DL.  This circuit performs a m*n bit parallel modulo 2 division of the received sequence by a given polynomial and transfers the remainder REM to a comparison circuit C where it is compared with a  zero byte or with an error code byte HEC contained in the sequence depending on the position of the first byte of the sequence on the bus.  Based on the result of the comparison and using translation tables a processor circuit PR determines the bit Position in the sequence of a bit error.  A correction logic CL corrects the received sequence.

Granted: 2005-05-17
Abstract: An anchor far attaching an object to a bone or bone-like structure includes a body and a plurality of barbs located in axially aligned, circumferentially spaced relation to each other about the body. The barbs have a normal configuration wherein they extend rearwardly and radially outwardly from the anchor body. The barbs may be elastically deformed.

Title: Charge equalization of series connected cells or batteries
Inventor: PACHOLOK DAVID R
IPC: H02J7/00
Filed: 1995-09-08
Granted: 1999-05-25
Abstract: An equalizer for equalizing the charge on several series-connected cells includes a transformer having plural windings on a core corresponding to the number of cells. The windings are tightly coupled to one another.  A switching device such as a MOSFET is connected to each of the windings, and a winding and a switching device are connected across each of the cells.  The switching devices are simultaneously switched at a relatively high frequency, e.g., 20Hz, and the voltage across the highest charged cell appears across each of the windings when the switching devices are on.  Current flows from the most highly charged cell to a cell or to cells of lower charge, with the charging current being proportional to the difference in voltage between the highest charged cell and each of the lesser charged cells.  Equalization is carried out with very little power consumption by the equalizer, allowing charging to take place in a rapid manner.

Granted: 1999-08-31
Abstract: An event history data recorder and method for recording data relating to a distinct event and pertaining to operation of a mechanism preceding and following each occurrence of such distinct event.    The  recorder comprises  a means  for  collecting  data pertaining to such operation and for formatting such collected data into a sequence of data elements.  The recorder includes a circular buffer  linked  to  the  collecting  and  formatting  means  for temporarily storing a preset number of the data elements.  The data elements are continuously stored on the circular buffer as a newest data element continuously writes over an oldest data element as a storage limit of the circular buffer is reached.  The recorder also includes a timer of predetermined duration which activates upon each occurrence of such distinct event.  The recorder additionally includes a memory device for retaining the data elements.  The data elements can be accessed therefrom for analysis of such operation of such mechanism surrounding such distinct event.  The recorder further includes a means, connected to the timer, for transferring the data elements from the circular buffer to the memory device wherein for each occurrence of such distinct event a preselected number of the data elements stored prior to, and including, an instant the timer deactivates is transferred by the transferring means from the circular buffer to the memory device.  A data log is thereby  formed within the memory device  from which  the  data elements may be accessed for analysis of such operation of such mechanism.
