Abstract: A three-dimensional woven fabric structural material
which can be widely utilised in various applications including
heat insulating material, noise insulating material, reinforcing
core material, and other interior decoration materials
and composite materials, curtain, blind and other expansible
structural materials, tent and agricultural protective
material, is integrally woven by a multi-ply weave having
three or more plies 1a...1c, wherein a number of cylindrical
or prismatic bag portions 2 extending in parallel in
one of the longitudinal and transverse directions are interconnected
in a plurality of rows extending in the other direction.
The bag portions 2 in each row are defined in bag
form by at least two woven fabric plies and are interconnected
through bound portions 3 in either of the two woven
fabric plies 1a...1c in said other direction. The bag portions
2 in adjacent rows have the woven fabric ply between
the two rows in common and are interconnected at staggered
positions. A creasing treatment is applied at the middle position
between the bound portions in the woven fabric plies
in the bag portions, whereby the latter are set to retain
their hollow three-dimensional form, or they are allowed to
be folded flat into the juxtaposed state. During weaving, by
means of either a multi-ply weave having three or more plies
or a two-ply weave, the bag portions are interconnected in
rows, and auxiliary yarns extending through the bag portions 
without being woven into the woven fabric plies are inserted
at the opposite ends in the woven width direction and/or at
required intervals in the woven width direction. The bag portions
are juxtaposed by tightening the auxiliary yarns and
then a creasing treatment is applied, or these portions are
heat-set without having a creasing treatment applied thereto,
thereby facilitating the production of the three-dimensional
woven fabric structural material.

Inventor: HETZLER STEVEN ROBERT
IPC: G11B19/00
Filed: 1996-06-27
Abstract: The present invention provides a data recording disk drive for use
in a portable, battery-powered computer having several power-save modes
of operation. The power-save modes are entered after a computed time
since the last data read or write command. The computed time to enter a
power-save mode is based on the computer user's real-time workload and is
thus continuously varying during operation of the disk drive. The disk
drive detects the current user workload by calculating the frequency of
disk drive accesses and based on this history determines which of a
plurality of power-save modes is appropriate and when to enter a
power-save mode. Each disk drive read or write access is detected and
used to compute a current access frequency. The current access frequency
is compared to a previously calculated and continuously updated threshold
frequency. The threshold frequency is representative of the access
pattern, e.g., uniform or sporadic, and is computed from equations that
include adjustable gain factors. The appropriate power-save mode is
entered when the current access frequency falls below the threshold
frequency. Intermediate power-save modes can be skipped, based on the
detected access pattern. The disk drive can also adapt dynamically to
varying workload situations, thereby saving more energy without degrading
performance. This is accomplished by adjusting the gain factors in
response to tracking the actual performance of the system, thereby
changing the threshold frequency. The disk drive also determines when to
exit a power-save mode without necessarily waiting for a user access.
The power-save modes can also be customized for different disk drive
products without the need to conform to some standard for setting fixed
times, or number of power-save modes. New user-selectable parameters,
such as on/off, performance, and energy targets can be used to replace
fixed mode-entry times. These parameters adjust the gain factors and
thus the threshold frequency. This alters the equations used to
determine when to enter a power-save mode.

Abstract: In a microcomputer internally comprising a circuit including a
CPU and operating in synchronism with an internal clock signal, and an
OSD controller operating in synchronism with the internal clock signal
and an external horizontal synchronous signal, an oscillation circuit is
coupled to an external oscillator, for generating the internal clock signal
used in common to the circuit and the OSD controller. An oscillation
control circuitry receives the horizontal synchronous signal for
generating a CPU stop request signal to the circuit before supply of each
horizontal synchronous signal, so that the circuit generates a CPU stop
signal after a stopping processing is completed. When the oscillation
control circuitry receives the CPU stop signal, the oscillation control
circuitry causes the oscillation circuit to stop generation of the internal
clock signal. Thereafter, in response to each horizontal synchronous
signal, the oscillation control circuitry causes the oscillation circuit to
restart the generation of the internal clock signal. As a result, the internal
clock signal is generated in synchronism with the horizontal synchronous
signal.
