Title: Ink jet recording device
Inventor: KOBAYASHI TETSUYA
IPC: B41J2/19
Filed: 1987-06-05
Abstract: PURPOSE:To prevent air suction through an ink jet nozzle by providing a plurality of piezoelectric ceramics with different pressure cyclic phases on the external wall of an ink chamber and forming a travelling waveform on the external wall by the phase difference. CONSTITUTION:A printer head is composed of sequentially joint components such as a pressure plate 1, a nozzle plate 2, a supply plate 3, a bypass plate 4, a tank plate 5 and a blind plate 6. When piezoelectric ceramics for ink induction 9,10 are given a sign wave at the time of driving the printer head, the ceramics generate a travelling wave. That is, the printer head is driven from a state where it is not driven, and at the same time, an alternating current signal is input from a pulse generator so that the polarities of the piezoelectric ceramics for ink induction 9, 10 are always reversed. This results in the deformation of the pressure plate 1. Furthermore, the pressure plate 1 is transformed to generate a travelling wave by proper selection of input signal frequency. This travelling wave enables ink to gain a propelling force for supply to a pressure chamber 13 side. Consequently, a predetermined pressure can be applied to an ink flying direction all the time, thus preventing air suction through an ink jet nozzle.

Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To evade the reduction of access speed of a bus bridge to a main memory by providing this computer system with two I/O interfaces and a local memory temporarily storing a data transaction. SOLUTION: Either one of CPUs 31, 32 sets up data transfer and control information is allowed to flow through a bus bridge 34.

Title: Atm terminal equipment
Inventor: KATAHIRA JUNYA
IPC: H04L12/28
Filed: 1995-06-08
Abstract: PURPOSE: To attain communication between function equipments by adding a MID value corresponding to a function equipment to data from each function equipment and sending resulting data from a channel control section to an ATM channel so as to use the MID as a multiplex identifier. CONSTITUTION: When an ATM channel control section 22 detects a call arrived from an ATM channel, the control section 22 informs it to a main controller 21. The controller 21 reads a current communication state from a communication management memory 211 to decide whether or not communication is possible, and when the communication is possible, incoming call processing is requested to the control section 22. Then the control section 22 executes communication reply processing and sends it to a reception information distribute section 24 upon the receipt of an information cell from the ATM channel. The distribute section 24 compares a MID in the cell with a MID stored in a MID function memory 25 and sends an information cell with the coincident MID to a function equipment.  A transmission information control section 23 receiving a call from the function equipment 3 references the memory 25 to read the MID corresponding to the function equipment 3 and the control section 22 sends a cell to the ATM channel.

IPC: H02G1/10
Filed: 1981-09-10
Abstract: PURPOSE:To decrease the tension to be exerted upon a submarine optical fiber cable during pulling up by disassembling the anchoring part of the junction of said cable or the body of the juncture in accordance with the electric signal from a terminal station on land. CONSTITUTION:When a fault arises in a submarine optical cable 4, the position of the fault point is searched by using a tester by optical pulses or electric pulses from a terminal station 19 on land. The signal corresponding to the juncture 5 nearest the same is transmitted from the station 19 by using the central support 7 and copper pipe 20 of the cable 4. Said signal is sensed with a driving device 15 for disassembling of the anchoring part which in turn transmits a driving signal to a disassembling device 16 for the anchoring part. The device 16 disassembles or melts the epoxy resin of an anchoring part 14 by gunpowder, chemicals, etc. thereby forcing the part 14 to lose an anchoring function. Thus  the tension to be exerted upon the cable 4 during pulling up of the cable 4 is decreased and the quantity of the cable to be replaced in the stage of repair is decreased.
