Abstract: In a method of integrally attaching a hollow member (10) to a cast
product by casting so that the hollow member communicates with a
hollow interior of the cast product (2a,2b), a closure member is fitted into an
open end of the hollow member so that the open end of the hollow
member is closed by the closure member (26,28,36,38). The closure member
projects from a core (16,18) for forming the hollow interior of the cast product
in a direction different from a direction in which the core is drawn out
of the cast product. A molten metal is poured into a casting mold
after the casting mold has been clamped. The closure member is
moved inside the core after solidification of the molten metal so that
the closure member is released from the fitting in the hollow member.
The core is drawn out of the solidified metal subsequently to the
moving step of the closure member.

Abstract: An electrochemical device for separating oxygen from an oxygen-containing gas
comprises a plurality of planar ion-conductive solid electrolyte plates and electrically-conductive
gas-impermeable interconnects assembled in a multi-cell stack. Electrically-conductive
anode and cathode material is applied to opposite sides of each electrolyte
plate. A gas-tight anode seal is bonded between the anode side of each electrolyte
plate and the anode side of the adjacent interconnect. A biasing electrode, applied to
the anode side of each electrolyte plate between the anode seal and the edge of the
anode, eliminates anode seal failure by minimizing the electrical potential across the
seal. The seal potential is maintained below about 40 mV and preferably below about
25 mV. A gas-tight seal is applied between the cathode sides of each electrolyte plate
and the adjacent interconnect such that the anode and cathode seals are radially offset
on opposite sides of the plate. The combination of biasing electrodes and offset seals is
particularly effective in eliminating anode seal failure.

Abstract: A vacuum circuit interrupter (10) has a coil (14) for generating an axially oriented magnetic field to maintain an electric arc in a diffuse rather than columnar mode upon opening of the interrupter (10). At least one of two electrodes (12, 16) having abuttable disc shaped contacts (22, 24) is movable along an axis (44) relative to the other and can be forced by an external mechanism to open. The electrodes (12, 16) are carried in a housing with an electrical insulator (48) between opposite end mountings (52, 54) that support the electrodes (12, 16) with the contacts (22, 24) in an evacuated enclosure. One of the electrodes (12, 16) is an assembly including a rigid supporting member (32) attached to one of the contacts (22, 24) and extending a length along the axis (44). A coil (14) is wrapped circumferentially around the supporting member (32) along this length, providing a conductive path to generate the axial magnetic field. The supporting member (32) provides a less-conductive path (e.g., a stainless steel sleeve) and the coil (14) is more conductive (e.g., copper), providing a durable and inexpensive structure.

Abstract: Data (e.g. legacy LAN traffic) segmented into
packets provide a header and a cell payload for each cell in
each packet. The cell payloads are transferred to a region
address in a host memory in accordance with determinations by
a control memory. When the cell payload is to be transmitted
from the host memory, the cell payload for a particular region
address is combined with the header stored in the control
memory for such address. Streaming data (e.g. voice or video)
occurs at a regular rate and is not necessarily broken into
packets. The streaming data is segmented to provide cell
headers and cell payloads. The cell payloads are then
transferred to a host receive FIFO in accordance with a
determination by the control memory and are stored in a data
sink. Cell payloads from a data source are transferred into a
host transmit FIFO at a particular rate and are transferred
from the host transmit FIFO preferably at a substantially
constant rate higher than the particular rate. These FIFO
cell payloads are combined with the headers in the control
memory. When the cell payloads in the host transmit FIFO
become almost depleted, the transmission of the cell payloads
from the host transmit FIFO is skipped to allow the host
transmit FIFO to receive additional cell payloads from the
data source. The transmit and receive FIFO's respectively
maintain cell alignment by providing particular controls with
respect to the minimum and maximum number of cell payloads in
the FIFO's.

Abstract: A motor vehicle window glass is connected to its drive mechanism by a holder (10) and a foot (7) which travels along a rigid slideway (3) e.g. of aluminium or is connected to a toothed drive rack. The holder and foot are made from a polymer material which is suitable for mechanical operation and are joined by a flexible connecting piece (15) of reduced cross-section, so that the tolerances imposed by the manufacture and assembly of the components are compensated for by the elastic deformation of the connecting piece. The holder, foot and connecting piece are moulded in one piece from a polymer with a Shore hardness of between A80 and D80, fixed to the glass by screws, adhesive or a clip-together assembly. The polymer is a polyurethane which can be moulded onto the glass by a reaction injection moulding process.

Abstract: The invention provides an internal information
backing up device by which, even if the information is
changed or the memory allocation is changed by
version-up of a firmware, the data structures of the
informations can be corrected automatically. When a
firmware in which the form of backup data is changed is
started, a backup data expansion processing element
expands, based on stored contents of a data structure
table, all labels of data structures into a RAM using
default values of a default value storage element. The
backup data expansion processing element compares a
version of the data structure table of the firmware and
a version of a data structure table in a non-volatile
RAM with each other. If they coincide with each other,
the backup data expansion processing element expands
the backup data of a backup data element into the RAM,
but if the versions do not coincide, the backup data
expansion processing element maintains the default
value.

Abstract: The pressure increases of a hydraulic pressure
control module for controlling the braking forces of
wheels are decided on the basis of wheel speeds (Vw)
and a vehicle speed (Vso) estimated from the maximum
wheel speed (Vw). In this case, on condition that
the incremental rate (DVso) of the vehicle speed
(Vso) exceeds a predetermined threshold value (α),
the vehicle speed (Vso) exhibited before the
incremental rate (DVso) exceeds the threshold value
(α) is kept as an estimated vehicle speed (Vso),
which is used for deciding the pressure increases.
Thus, the pressure increases can be appropriately
decided even in a situation where a motor vehicle
passes through a very-low-µ road part or a drop in
road level.

Abstract: The present invention provides a method of simulating a process for
oxidation of silicon. The method comprises the following steps. A time "t"
of oxidation calculation is set at zero. An effective surface oxidant
concentration of a silicon surface exposed to an oxygen atmosphere is
calculated assuming that a spontaneous silicon oxide film as an initial
silicon oxide film extends over the silicon surface. The time "t" of
oxidation calculation is forwarded by a predetermined time increment Δt.
An oxidation rate is calculated by use of one of the effective surface
oxidant concentration and the surface oxidant concentration. A new silicon
surface is formed based upon the calculated oxidation rate and the time
increment Δt. Variations in thickness of the silicon oxide film over time are
found by a deformation calculation. There is verified whether or not the
time "t" of oxidation calculation reaches a predetermined end time so that
if the time "t" of oxidation calculation reaches the predetermined end time,
then a current simulation is ended, whilst if the time "t" of oxidation
calculation does not reach the predetermined end time, then an oxidant
diffusion equation is solved for a deformed silicon oxide film to calculate
the surface oxidant concentration of the silicon surface to be oxidized. A
loop comprising the sequential third to seventh steps is repeated until the
time "t" of oxidation calculation reaches the predetermined end time.
