Inventor: IKEDA CHINATSU
IPC: H04L49/9015
Filed: 1993-09-01
Abstract: In the packet switching apparatus of the present invention, packets are inputted, parallel-expanded by a serial-parallel converter, multiplexed on a time division multiplexer, and address information of the packets is discriminated by address filters provided corresponding to the output ports. The address filters receive packets carrying relevant addresses and transmit them to corresponding buffers for storage. The buffers monitor the number of stored packets, and according to the results of comparison of the number of stored packets and buffer capacity, send control signals to reserve memory control assemblies to effect connection and disconnection between the reserve memories and the buffers. The stored packets are then sent from the buffers to the output ports.

Title: Sweep frequency vibrator
Inventor: ROESSLER DENNIS E
IPC: G01V1/155
Filed: 1994-02-23
Abstract: ABSTRACT OF THE DISCLOSURE       A sweep frequency vibrator is set forth. It has an elongate cylindrical housing closed at the top and bottom ends. On the interior, there is a reactionary mass fixed to identical upper and lower piston ends. They are received in seal isolated chambers, one being formed in a moveable plug.  The plug is moved to thereby vary the spacing of the chambers. As the frequency is changed, plug is moved to assure sufficient clearance from the excursion of the reactionary mass. Hydraulic oil under pressure is delivered to control valves, one for each piston end. The two control valves and piston ends have very short flow lines. Moreover the excursion permitted for the pludg assures operation without bottoming out.

Title: Single step developable negative working and positive working printing plate and imaging process
Inventor: ADELMAN MICHAEL W
IPC: G03F7/095
Filed: 1994-05-03
Abstract: ABSTRACT     A lithographic printing plate precursor and process for its utilization have been discovered through which negative and positive original images can be printably reproduced on the plate precursor in substantially fewer development steps. The precursor plate is exposed sequentially to either the negative or positive original with the resultant image subsequently developable in a single process or step. The process is achieved by using a precursor plate having two coatings of significantly different photographic sensitivity to light, i.e., speed as characterized by "camera speed" or "contact speed" and imagewise exposing the originals in sequence to alternative speeds. The contact speed coating may be negative-working or positive working while the camera speed coating is negative-working. The camera speed coating is developed followed by exposure of the contact speed coating. Images produced at camera speed are removed and non-image bearing portions; of the contact speed coating are removed. The remaining image areas corresponding to the negative and positive originals are treated to provide positive printable images.

Title: Methods and apparatus for detecting electrode separation
Inventor: ROSSI ALESSANDRO
IPC: B23K11/25
Filed: 1994-05-18
Abstract: Methods and apparatus for identifying the occurrence of fusing electrical attachment during fusing operations are provided. After a conventional fusing operation is complete, an electrical signal is applied to the fusing electrode while the fusing electrode is returned to its home position. The electrical signal is monitored to determine whether a Circuit path exists from the fusing electrode through the fused conductors to the ground electrode. The presence of a path would indicate that the fusing electrode has become attached to the fused conductors.        An alternate embodiment is also described in which the force required to withdraw the fusing electrode is monitored while the electrode is returned to its home position. If the measured force does not fall within predetermined limits, or if the measured force varies during electrode movement, fusing electrode attachment has occurred.
