Abstract: The present invention is intended to improve a
throughput of data transmission by efficiently
retransmitting a requested frame between two terminals
directly connected each other in a packetized data
transmission system. Data is transmitted in frames each
of which is constructed a flag sequence field (21) for
delimiting a frame, a forward information field (22)
including a number for identifying a frame, a backward
information field (23) containing a history of frame-numbers
of correctly received frames, an information
field (24) including user data of a fixed length and a
code for error-detection field (25) for detecting an
error of the received frame. With a frame correctly
received, a receiving terminal updates a history of
correctly received frame-numbers and sets it in a
backward information field of a frame to be transmitted
to a transmitting terminal. With a frame incorrectly
received, history information for precedent correct
frame is set the backward information field of the
frame.

Abstract: A power supply includes a series resonant converter (100), having at least one switch and at least one capacitor. The converter (100) includes a switching circuit (120) including an enable input. A voltage sensing circuit (124) that determines the earliest safe switching time of the switch is provided. The safe switching time is the time that will prevent a peak voltage on the capacitor from exceeding a predetermined threshold for a next cycle of the converter. The voltage sensing circuit (124) provides an enable signal to the enable input when the earliest switching time has passed, to enable the switching circuit (120). A pair of output terminals connected to the series resonant converter (100) receives the output. The power supply is particularly intended to provide a welding power supply.

Abstract: A type of disk in a reproducing device is accurately
determined prior to data reproduction. To determine whether
the disk type is Compact Disk (CD) or Digital Video Disk
(DVD), a track pitch on the disk is examined, while the
difference between the DVD Single Layer and DVD Dual layer is
based on disk reflectance values. When the determined disk
type turns out to be incorrect, an operation is carried out
for estimating the correct disk type based on the highest
likelihood of the disk type following the initial (incorrect)
decision. The process is carried out until the correct disk
type is identified, or the disk is determined to be unusable.

Abstract: In a system using a microprocessor including a cache
memory, a specific memory cell row including at least one row
of memory cells is provided to a cache memory cell array of the
cache memory so as to be used as a write back buffer. When
data is to be saved in the specific memory cell row (write back
buffer), the memory cells aligned in one row in the cache
memory cell array are selected by an arbitrary word line, and
all the data to be saved are simultaneously written in the
specific memory cell row (write back buffer) through bit line
pairs in a batch. Therefore, since the data to be saved can be
written in the specific memory cell row (write back buffer)
without using a data bus, the number of accesses to be made to
the cache memory can be decreased. As a result, the throughput
can be improved and the power consumption of the microprocessor
can be decreased. In addition, since the write back buffer is
constituted by the specific memory cell row, the chip area can
be decreased.
