Inventor: ASAI HIROKI
IPC: B41J2/14
Filed: 1994-11-10
Abstract: An ink ejecting device includes ink channels intercommunicating with slits and air channels intercommunicating with another slits. The ink channels and the air channels have a narrow shape with a rectangular cross-section, and all of the ink channels are filled with ink and the air channels are filled with air. An LSI chip applies a voltage V to a pattern conducting to metal electrodes positioned in air channels located at both sides of an ink channel from which the ink is to be ejected and connects the other patterns connected to metal electrodes in other air channels not adjacent the ejecting ink channel and a pattern conducting to the metal electrodes of the non-ejecting ink channels to a ground line. Therefore, the ink ejecting device of the above structure requires no insulation between ink and electrodes as the working electrodes do not contact the ink.

Title: Disk drive with shock detection based on thermoresistive signal from magnetoresistive head
Inventor: KASIRAJ PRAKASH
IPC: G11B21/21
Filed: 1997-04-02
Abstract: A magnetic recording disk drive with a magnetoresistive (MR) read sensor or head has a shock and vibration detection circuitry responsive to a thermoresistive signal contained in the signal from the head. The MR head is heated by an electrical bias current and is supported on the head carrier near the surface of the disk. External shock or vibration to the disk drive alters the spacing between the carrier and the disk, which causes fluctuations in the head temperature due to cooling of the heated head by the disk. These temperature fluctuations are reflected in the signal from the head as a thermoresistive signal comprising modulation of a baseline voltage level. The shock detection circuitry compares positive and negative excursions of this thermoresistive signal with a predetermined threshold voltage level. When the threshold is exceeded, indicating an external shock or vibration in excess of an allowable limit, writing of data is inhibited.

Abstract: A device for testing multi-fibre optical cables includes a number
of test stations into which an end of a cable under test is plugged.
Some to the test stations provide for the attachment of an array
connector, while others provide for the attachment of a number of
discrete connectors. The optical input/output port of an OTDR unit is
connected to each of the test stations through an optical switch, which
connects this port with only one such station at a time. within each
station, signals from the optical switch are divided among a number of
light paths by a splitter, which also returns signals from these light
paths to the OTDR through the optical switch. The various light paths
within each station include fibre optic jumpers which vary in length, so
that a single test pulse from the OTDR is reflected back from a number of
interfaces in the cable under test as a train of pulses.

Title: Self-calibration system for logarithmic amplifiers
Inventor: COMINO VITTORIO
IPC: H03F1/30
Filed: 1997-12-16
Abstract: Temperature and technology-independent self-calibrating monolithic
logarithmic amplifier systems that use integrated cascades of current-summing or
voltage-summing differential-limiter gain stages are disclosed. Each stage is trimmed
and stabilized by a respective bias replicator cell and a current mirror cell. The bias
replicator provides a bias current control signal in response to a change in a given
difference between bias currents in a differential pair of amplifiers controlled by a
predetermined differential calibration voltage. The differential pair is identical to a
differential pair in the limiter amplifier. The differential calibration voltage  E lin    is well-within
the linear portion of the amplifier's transfer curve during operation, so that the
proportional relation between  E k    and  E lin   , which is the same as that between the given
difference between currents and the correct bias current value  I B   , remains constant
throughout. The bias replicator signal then varies the input bias current of the limiter
amplifier to correct for temperature-related and technology-related bias-current errors.
The current mirror uses an op amp connected to a calibration voltage equal to the
correct limit voltage of the amplifier to detect a change from that voltage across a
variable calibration resistance. The current mirror provides a signal to that variable
calibration resistance to cancel that change, and to matching variable load resistances in
the gain cell to correct for temperature-related and technology-related load-resistance
errors.

Abstract: The method involves automatically accepting an incoming telecommunications connection. The caller is given an audible guide to the through-dial or re-dial function which requires him to enter re-dialling commands in the form of multiple frequency coded signals or speech commands contg. an identifier definitely associated with an extension (6,7,8) to be selected. The re-dial command is transferred to the telecommunications system like a speech signal and is converted into an electronic relay signal contg. an electronic extension identifier. Alternatively, the re-dial command is converted into an electronic relay signal, whereby the speech signal is associated with as predefined speech pattern associated with an extension and a relay signal is generated which contains an electronic identifier for this known extension. Manual relay by entry of a keyboard command is simulated by the relay signal which allows the telecommunications system to pass the connection to the ex tension corresp. to the redial command. An Independent claim is also included for an arrangement for implementing the method.
