Patent EP-0391829-A3 (EP)
Title: Automatic gap adjusting mechanism
IPC: B41J25/308
Filed: 1990-03-27
Abstract: Before printing operation, the print head is driven to the 
platen (17) to press the print form (18) against the 
platen and then retracted through a predetermined distance 
to provide a predetermined amount of gap between the print 
form and print head regardless the thickness of the print 
form. A planetary gear (4) is provided to engage with a 
drive gear (3) supported on the drive motor shaft (1) and 
is biased by a spring (12) to operatively engage with a 
sun gear (5) which is engaged with a rotary shaft (15) 
linked to the head carriage through a cam mechanism 
(9a,9b), so that the drive power of the motor can be 
delivered to the rotary shaft through the drive gear, 
planetary gear and sun gear. When the print head presses 
the print form against the platen, the reaction of the 
planetary gear from the sun gear is increased to move the 
planetary gear around the sun gear against the spring, so 
that the drive power can be no longer delivered to the sun 
gear to result in the rotation of the rotary gear being 
stopped. In response to sensing the stop of the rotary 
shaft, a control circuit (22) provides a control signal to 
the motor for reversely rotating it by a predetermined 
amount to make the planetary gear deliver the reverse 
rotation to the rotary shaft through the sun gear, so that 
the print head is driven to move away from the platen to 
provide a predetermined amount of gap.

Patent EP-0465066-A3 (EP)
Title: Method and apparatus for transferring data between a data bus and a data storage device
IPC: G06F11/10
Filed: 1991-06-21
Abstract: A bus interface between a data bus and data storage devices provides error protection for multi-byte data packets received from the bus and intended for storage on an associated storage device by checking the data symbols in a packet for errors using check sum and parity symbols included in the packet. The bus interface then (i) encodes a predetermined number of data symbols to generate error detection symbols, (ii) again checks the data symbols for errors using the parity bits, and (iii) stores the data and associated error detection symbols in one of a series of linked buffers. Each buffer holds enough the data and associated error detection symbols to fill one storage unit, or sector, on an associated storage medium. A storage interface later retrieves the buffered data and error detection symbols, combines them with the address of a designated storage sector, and encodes the symbols to generate error correction symbols. It then stores the encoded data, and error detection and correction symbols in the designated sector. When the storage interface later retrieves the symbols from the sector, it corrects errors in the data using the retrieved error correction symbols. It next removes the sector address from the error detection symbols and returns the data and error detection symbols to the bus interface. The bus interface (i) generates parity bits, (ii) checks for errors using the error detection symbols, (iii) generates check sum symbols and (iv) transmits the data, check sum and parity symbols over the bus. If the bus interface at any time detects an error, it stops the data transfer operation. <IMAGE>

Title: Satellite control link for paging system
IPC: H04B7/185
Filed: 1991-11-08
Abstract: A paging system includes a satellite uplink (40) for assembling paging information and transmitting it to a satellite (26). The satellite (26) is then operable to transmit in a simulcast manner all the information to various regional paging systems (42). Each of the paging systems (42) includes a plurality of towers (10) each containing a satellite receiver (50), a satellite dish (48) associated therewith and a paging transmitter (52). Each of the satellite receivers (50) are operable to receive the information transmitted from the satellite (26) at substantially the same time such that there is no phase difference between any of the towers, regardless of location. Therefore, the transmitters (50) can transmit through antennas (12) information at the paging frequency with substantially no relative delays relative to each of the antennas (12). A backup link receiver (28) is provided for interfacing with a backup link transmitter (70). In the event of a failure of the receivers (50) or the satellite (26), the link transmitter (70) will transmit the paging information directly to select ones of the towers (10) over a separate frequency.

Title: Recording apparatus and recording mechanism carrier.
Inventor: WADA TOSHIHIDE
IPC: B41J25/34
Filed: 1994-01-12
Abstract: A recording apparatus for recording on a recording medium by use of a recording mechanism which travels along the recording medium comprises a carrier which enables the recording mechanism to travel along the recording medium, the carrier being capable of holding the recording mechanism detachably, and a carrier driving mechanism which enables the carrier to travel along the recording medium, the carrier driving mechanism prohibiting the movement of the carrier in an arbitrary position in the traveling area of the carrier. In this way, when the recording mechanism is attached to or detached from the carrier, the movement of the carrier is prohibited, thus making it possible to fix the carrier without any particular mechanism to suspend the movement of the carrier for a reliable and sound attachment or detachment of the recording mechanism to or from the carrier, and at the same time, to implement the miniaturization and lower cost of the apparatus. <IMAGE>

Abstract: A video switching system 108 automatically establishes video communications
between an agent terminal 110 and a video communications device 104. A telephonic
switch, such as an automatic call distributor (ACD) 102, selects which agent terminal 110
receives the video communications and generates reports relating to the video
communications. A programmable switch 105 receives an initial request from the video
communications device 104 to establish video communications. A computer system 112
detects the initial request and instructs the ACD 102 to select the agent terminal 110
which is to receive the video communications. The ACD 102 selects the agent terminal
110, or an agent associated with the agent terminal 110, using known methods and
transmits the selected agent terminal 110 to the computer system 112. The computer
system 112 instructs the programmable switch 105 to route the video communications to
the selected agent terminal 110. When the ACD 102 receives the instructions to select the
agent terminal 110, the ACD 102 begins to collect information relating to the video
communications. The computer system 112 detects when the video communications has
ended and notifies the ACD 102. In response, the ACD 102 stops collecting information,
such as communication time, and makes the agent terminal 110 available.

Abstract: A digital encoder for compressing a digital input signal derived from an analog signal to reduce the number of bits required to represent the analog signal with low quantizing noise. In the encoder, a digital input signal representing the analog signal is divided into three frequency ranges. The digital signal in each of the three frequency ranges is divided in time into frames, the time duration of which may be adaptively varied. The frames are orthogonally transformed into spectral coefficients, which are grouped into critical bands. The total number of bits available for quantizing the spectral coefficients is allocated among the critical bands. In a first embodiment and a second embodiment, fixed bits are allocated among the critical bands according to a selected one of a plurality of predetermined bit allocation patterns and variable bits are allocated among the critical bands according to the energy in the critical bands. In the first embodiment, the apportionment between fixed bits and variable bits is fixed. In a second embodiment, the apportionment between fixed bits and variable bits is varied according to the smoothness of the spectrum of the input signal. In a third embodiment, bits are allocated among the critical bands according to a noise shaping factor that is varied according to the smoothness of the spectrum of the input signal. All three embodiments give low quantizing noise with both broad spectrum signals and highly tonal signals. <IMAGE>
