IPC: B22D11/124
Filed: 1990-02-27
Abstract: PURPOSE:To improve the productivity of continuous casting machine by forming cooling water passage with plural guide rolls, sealing device among them and a cast slab and forcedly flowing the cooling water crossing at the right angle to shifting direction of the cast slab in there. CONSTITUTION:The cast slab 1 is guided with plural guide rolls 2 arranged as mutually facing just below the mold 4. Gaps among the guide rolls 2 are sealed with a jacket 5 in the sealing device. The cooling water passage 6 is formed with the guide rolls 2, jacket 5 in the sealing device and the cast slab 1.

Title: Communication method and communication system
Inventor: YOKOTA HIROSHI
IPC: H04L12/42
Filed: 1992-03-05
Abstract: PURPOSE:To simplify the circuit configuration of each communication node by sending out the same cell on two transmission lines, and transferring the cell by a reception selection system. CONSTITUTION:A communication node 1 sends out user information received from a terminal 10 to the transmission line 9. In such a case, the reception selection system in which the sending side of the communication node always sends out the cell to both transmission lines 9, and a reception side selects data convenient for the reception side is employed. At the reception side, a cell disassembling part 5 checks the continuity of the SR number of the cell arriving at its own node, and deletes the cell provided with the SN number other than the SN number scheduled to receive at the next time. When a certain cell to be deleted on the middle way of transmission exists, no serial number can be obtained in the SR number to be received, and also, the inversion of sequence when the cell arrives can be recognized by observing the passing of the SN number. When the SN number is continuous, the cell disassembling part 5 judges that no deletion of the cell is performed, and writes the user information on a reception buffer 6.

Therewith, an elongation is generated also in a knife-edge steel portion which is to form an intermediate body of the knife. Hence, an internal deformation stress is balanced by giving a full- surface elongation to the portion which is to form a cutting edge portion of the clad plate. Thereafter, the clad plate is press-punched into a kitchin knife shape, roughly.machined and finish-edge-machined while having said internal deformation stress remained therein for a hammer-patterned kitchin knife with a cut-edge portion 1 and a body portion 2 to be produced efficiently and also for its sharpness to be increased drastically.

Title: Control information reducing system in adaptive forecasting coding
Inventor: HAMADA TAKAHIRO
IPC: G06T9/00
Filed: 1990-03-02
Abstract: PURPOSE:To improve signal transmission efficiency by inhibiting the transmission of control information for selecting a forecasting function to the decoding side when the coding side can decode a signal without using the control information. CONSTITUTION:The coding side detects a case capable of decoding a signal without using the control information for selecting the forecasting function, and at the time of detecting the case, inhibits the transmission of the control information to the decoding side. When the control information is not received, the decoding side extracts an optimum forecasting function from a forecasting function formed from reproduced picture elements on the decoding side itself in the same procedure as that of the coding side and a transmitted quantized representative value and reproduces each picture element. Thereby, the decoding side can reproduce the picture element by selecting the optimum forecasting function corresponding to each picture element even if the control information is not transmitted. Since the volume of control information to be transferred from the coding side to the decoding side can be reduced, the signal transmission efficiency can be improved.
