Abstract: The invention relates to a configuration having two internal
clock systems in a synchronous DRAM memory circuit such that
an external clock signal (CLK) is transferred to a switch (S1)
to a first internal clock system (1) that generates a signal
for controlling the output. Further, in case the switch (S1)
is off, a switch (S2) is on such that the internal clock
system (1) enters to a reset state and the internal clock
system (2) is in the stand-by state. Next, when the /CAS
signal is received the internal clock system (2) can operate
it any time in accordance with the external clock signal CLK.
As a result, the control of a burst data transfer operation is
carried out from the internal clock system (2).

Abstract: There is disclosed a synchronous motor drive in which
in a record disc drive of an information recording device a
quantity of generated excitation noise is reduced to a small
level to which a reading/writing signal is not influenced
and a substantial motor generation torque is prevented from
lowering. An absolute value of a maximum voltage gradient
of a coil excitation voltage waveform is set to a certain
value or less. The waveform alternates at a synchronous
frequency which is determined by the number of poles of a
rotating magnetic field produced in an air gap by a stator
winding and the number of revolutions.

Abstract: A combined filter and HME has a rectangular housing 1 with an inlet port 5 and an
outlet port 14. A pleated filter element 20 is located in the housing towards the outlet port 14
and an HME element 21 is located towards the inlet port 5. An oval deflector 10 between the
HME element 21 and the inlet port 5 is oriented with its longer axis aligned with the shorter
lateral dimension of the housing 1, so that gas from the inlet is deflected preferentially along
the longer lateral dimension of the housing, thereby giving a more evenly distributed gas flow
over the surface of the HME element.

Abstract: A computer system that implements communication support with a minimum amount
of main memory. The computer system provides a Basic Input/Output System (BIOS) for
execution in Random Access Memory (RAM). Included in the BIOS is the communication
initialization and runtime code. Upon initialization, the communication initialization code is
executed, configuring and initializing communication devices, including a Universal Serial Bus
(USB) device. After the initialization, the runtime communication code is moved to a secure
memory, such as System Management Mode (SMM) memory. The runtime communication
code is executed in response to an interrupt to the secure memory. If the secure memory is
SMM memory, then a SMI will trigger the execution of the communication code. The main
memory is not accessed to execute the runtime communication code.

Abstract: A plastic optical fiber (A) having a core and a cladding portion is connected to a
light-receiving element such as a photo-diode (PD) through a connecting
structure. The connecting structure such as a light-relay element (52) is
interposed between an end face of the plastic optical fiber and a light-receiving
face (Rf) of the photo-diode in the same axial direction. The connecting
structure has a frusto-conical shape having a cylindrical surface and end faces.
The diameter of the structure decreases gradually from the fiber side towards
the photo-diode side, so that its fiber-side face has a size corresponding to that
of the core portion of the fiber, whilst its photo-diode side face corresponding
to that of the light-receiving face. By virtue of this configuration, the
connection loss between the plastic optical fiber and the light-receiving element
can be minimized.

Abstract: A radially expandable stent (10) made from a cannula or sheet of biocompatible material that includes at least one longitudinal segment (14) comprised of a series of laterally interconnected closed cells (13). Each closed cell of a longitudinal segment is defined laterally by a pair of longitudinal struts (15, 16) that are interconnected at each end by a circumferentially adjustable member (19, 20). When the stent is expanded using a balloon (47), the opposing circumferentially adjustable members deform to allow circumferential expansion of the longitudinal segment, while the length of the segment, as defined by the longitudinal struts, is maintained. Self-expanding versions of the stent utilize a nickel-titanium alloy. Adjacent longitudinal segments are joined by flexible interconnection segments (21) that permit the stent to bend laterally. The flexible interconnection segment is comprised of curvvilinear struts (22, 23) that form a series of serpentine bends (81) that distribute lateral bending forces. In a preferred embodiment, a short strut interconnects a longitudinal segment and adjacent interconnection segment. Each interconnection strut attaches to the longitudinal segment within a region (27) at the end (17) of a longitudinal strut (15) dividing two adjacent closed cells.

Abstract: A recycled asphalt roofing material (20) for use on sloped
roofs, which provides the required elevated melt point
without using prior art methods of oxidising the asphalt
prior to incorporation into the roofing material is
provided. The recycled asphalt roofing material (20) is made
up of approximately 30% flux asphalt and approximately 70%
reclaimed asphalt roofing material. The fibrous backing in
the reclaimed material modifies the asphalt in such a way
as to provide the required elevated melt point. The
manufacturing process for recycled fibreglass mat-based
roll and shingle roofing, in its preferred embodiment,
consists of impregnating a roofing material backbone (22), such
as a fibreglass or polyester mat with recycled asphalt
material to form inner and outer layers (24) of recycled
material and then applying optional second inner and outer
layers (26) of standard asphalt coating to the inner and outer
layers of the recycled material (24). The second coating
encapsulates and seals the recycled material and thus
ensures that the recycled roofing material will have the
same longevity as prior art asphalt roofing materials.
