Abstract: A system (10) and method for providing simultaneous data reading and writing for a random access memory (18) include storing (62) new data (14) and (60) a corresponding new data address (26), comparing (32) the new data address to a current read address, and substituting (38) the new data for the data at the current read address at the output (38) while simultaneously writing (38) the new data into the memory (18). The system and method are particularly suited for application in space-based communication satellites which utilizes continuous memory read accesses since the invention provides the functionality of a dual-ported RAM while being implementable with fewer gates and less complex control circuitry to provide reduced power consumption.

Title: Method of monitoring contactor operation
Inventor: TENNIES CHARLES JOSEPH
IPC: H01H47/00
Filed: 1997-06-09
Abstract: Upon initiation of operation of a contactor (12) from an unactuated condition to an actuated condition, the maximum magnitude of an initial current conducted to the coil (16) of the contactor is determined. Once the contactor (12) has been operated to the closed condition, the holding current is checked to determine if it exceeds a reference current. The reference current is a predetermined function of the maximum initial current. If the reference current is less than the holding current, a malfunction signal is provided. In another embodiment of the invention, a sensor (120) is provided to sense the position of movable contacts (20b, 22b) connected with an armature (50b) of the contactor (12b).

Abstract: Sources of meat having a high fat content, such
as pork trimmings, are processed in a manner by which meat
products prepared therefrom have a dramatically reduced
fat content while retaining the desirable functionality of
the unprocessed meat sources. The fat-containing meat
trimmings or the like are comminuted, phosphated, heated
and centrifuged under specific processing conditions in
order to provide unformulated raw low-fat or no-fat meat
having a fat content of not greater than on the order of
about 1.5 percent by weight while having excellent
functionality. The unformulated reduced fat meat is
formable into a variety of familiar meat products,
including wieners, sausages, hamburger patties, and the
like, thereby providing products having taste, appearance,
texture and other qualities which are substantially
indistinguishable from products prepared from higher fat
unformulated raw materials but which have very low fat
contents. The phosphate use accounts for a fat reduction
of from about 10% to about 40%.

Abstract: A replaceable filter cartridge for use in a fluid filter assembly includes a substantially cylindrical filter element including a pair of oppositely disposed filter element ends. A first endplate is bonded to one of the filter element ends so as to close the end and prevent fluid leakage therethrough. A second endplate is bonded to the opposite filter element end so as to close the opposite end and prevent fluid leakage therethrough. The second endplate includes an outer annular wall which is sized so as to create a noticeable distance of separation between the second endplate outer wall and the outer surface of the filter element and thereby define an annular clearance space therebetween. The outer wall of the second endplate is annular and substantially concentric with the filter element and provides a lip or free edge for the snap-on assembly of a closing lid member. By configuring the lid member with a series of snap-over fingers, it is possible to simply snap the lid onto the second endplate and thereafter use the lid for handling and manipulation of the replaceable filter cartridge.

Title: Solid-state relay
Inventor: SUZUMURA MASAHIKO
IPC: H01L29/06
Filed: 1998-06-29
Abstract: A solid state relay composed of a series connected pair of
LDMOSFETs has a minimized output capacitance. Each LDMOSFET
is configured to have a silicon layer of a first conductive type, a drain
region of the first conductive type diffused in the top surface of the
silicon layer, a well region of a second conductive type diffused in the
silicon layer in a laterally spaced relation from the drain region, and a
source region of the first conductive type diffused within the well region
to define a channel extending between the source region and a
confronting edge of the well region along the top surface of the silicon
layer. Each LDMOSFET is of an SOI (Silicon-On-Insulator) structure
composed of a silicon substrate placed on a supporting plate, a buried
oxide layer on the silicon substrate, and the silicon layer on the buried
oxide layer. The well region is diffused over the full depth of the
silicon layer to have its bottom in contact with the buried oxide layer, so
that the well region forms with the silicon layer a P-N interface only at a
small area adjacent the channel. Because of this reduced P-N interface
and also because of the buried oxide layer exhibiting a much lower
capacitance than the silicon layer, it is possible to greatly reduce a drain-source
capacitance for minimizing the output capacitance of the relay in
the non-conductive condition.

Abstract: The present invention relates to a charged particle
beam exposure method, wherein exposure data having
exposure pattern data for each of a plurality of sub-fields
located in a main field are acquired from pattern
data for each of the sub-fields and a sample is exposed in
accordance with the exposure data. The method comprises
the steps of: forming a plurality of areas having
different shapes, in accordance with patterns in the sub-fields,
and acquiring pattern densities in the areas;
correcting the pattern densities in accordance with
pattern densities for areas surrounding the areas and with
distances between the areas; generating auxiliary exposure
patterns in the areas when the pattern densities for the
areas are lower than a predetermined reference exposure
density; and exposing the sample in accordance with the
exposure data obtained by adding the data for the
auxiliary exposure patterns to the pattern data. According
to the present invention, a variable area can be formed,
the number of areas can be reduced, and data processing
can be performed more efficiently.

Also, the value of (α2 - α1)/α1 ≥ -0.30, where a value of
electric resistance between a terminal (13) and a center
electrode (3) is α1 at 20°C and α2 at 150°C, so that
deterioration of the radio frequency noise prevention

suppressed. The resistor composition contains semiconductive
ceramic particles whose temperature coefficient of electric
resistance shows a positive value, or a negative value of
relatively small absolute value, (e.g., TiO 2  particles having
