Patent EP-0400678-A3 (EP)
Title: Signal recording/reproducing apparatus
IPC: G11B20/10
Filed: 1990-06-01
Abstract: A signal recording/reproducing apparatus equipped with 
a recording head section for recording signals on a 
recording medium and a reproducing head section for 
reproducing the signals recorded on the recording medium. 
The recording head section is arranged to record the signal 
to form N recording sub-tracks on the recording medium and 
the reproducing head section has M reproducing sub-heads 
which trace the N recording sub-tracks to reproduce the 
recording signal. The pitch of the M sub-heads thereof is 
equal to a pitch of the recording sub-tracks and the number 
M of the sub-heads is greater than the number N of the 
recording sub-tracks. The reproducing head section is 
coupled to a reproduction signal detecting section which in 
turn eliminates the interference and the crosstalk between 
adacent tracks from the reproduced signal due to the 
reproducing head section. This arrangement allows narrowing 
the track pitch to increase the recording capacity and 
extremely improving the transfer rate concurrently with the 
elimination of the the interference between the adjacent 
codes and crosstalk between the adjacent tracks.

Abstract: The invention relates to a method for transmitting packet data in a cellular system. The number of time slots in a TDMA frame dedicated for packet transmission varies according to transmission needs and each logical channel consisting of corresponding time slots in consecutive TDMA frames is independent of the other logical channels. A data packet is encoded in an information channel frame consisting of N-1 information bursts, and between the frames there can be an acknowledge/retransmission request burst (ARQ) reporting that a received frame was error-free or requesting retransmission. Thus, the information channel consists of repeated sequences of N bursts. Also disclosed are the structure of a packet paging burst (PP), packet random access burst (PRA), packet access grant burst (PAG), acknowledge/retransmission request burst (ARQ) as well as the use of the bursts in starting and maintaining the transmission. <IMAGE>

Abstract: PLL circuit which can be put into a locked state in a
short time. The PLL circuit has a phase comparator, a loop
filter and a voltage controlled oscillator. The phase
comparator is provided with frequency adjusting (or matching)
circuits that are operative to charge the loop filter in a case,
in which it is detected that an oscillation frequency of the
voltage controlled oscillator is lower than a frequency of an
input signal, so as to increase the oscillation frequency of the
voltage controlled oscillator until it is detected that an
oscillation frequency of the voltage controlled oscillator is
higher than the frequency of the input signal, and for
discharging the loop filter in a case, in which it is detected
that an oscillation frequency of the voltage controlled
oscillator is higher than a frequency of an input signal, so as
to decrease the oscillation frequency of the voltage controlled
oscillator until it is detected that an oscillation frequency of
the voltage controlled oscillator is lower than the frequency of
the input signal. The phase comparator is further provided with
phase adjusting (or matching) circuits for adjusting a phase of
an output of the voltage controlled oscillator to a phase of the
input signal after the oscillator frequency of the voltage
controlled oscillator is adjusted to the frequency of the input
sinal. Thus, a time required to adjust the oscillation
frequency of the voltage controlled oscillator can be
considerably reduced.

Abstract: An ink jet print head identification system for
providing print head identifying information to the
electronics of an ink jet printer includes one or more
programmable drain transistors (80,82,84,86) integrated
onto a print head chip. Existing address lines
(50,52,54,56) that interconnect the printer electronics
and print head electronics are used to serially read the
digital contents of each programmed transistor. The
printer electronics reads each bit by combinationally
applying a pull up voltage on two of the address lines
while pulling down the voltage on one address line. If
the drain (90,92,94,96) of the transistor being read is
programmed as an electrically conducting short, then the
transistor will turn on and the voltage level on one of
the pulled up address lines will not reach a logic high.
If the drain is programmed as a non-conducting gap, the
transistor will not conduct and the voltage level on
both pulled up lines reach a logic high. The printer
electronics detects whether the voltage level on both
lines is a logic high and accordingly determines the
digital contents of the identification circuit. After
each bit has been read, the printer electronics
determines print head identifying information based on
the bit pattern that was retrieved from the
identification circuit.
