IPC: H04N21/2383
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To generate a system clock of a system decoder without receiving the effect of a delay fluctuation caused on a network. SOLUTION: A difference (RTS1) between the number of clocks (EPAT1) (clocks synchronous with a network clock) that is counted between the arrival interval of a PCR packet P1 and that of a PCR packet P2 outputted from a system encoder to a transmitter and number of system clocks (a difference between EPCR1 and EPCR2) that is counted for the EPAT1, is inserted to a PCR packet P1, and the resulting packet is fed to a receiver. The receiver estimates a deviation between the system clock of the system encoder produced at the arrival interval (RPAT1) of the receiver between the PCR packet P1 and the PCR packet P2 and the clock signal synchronously with the network clock on the basis of EPAT1 and RTS1, and replaces the PCR with an MPCR calculated on the basis of the estimated value. Thus, the system decoder can generate a system clock synchronous with the system clock of the system encoder.

Title: Erosion resistant formed product for handling molten metal
Inventor: AOKI MIKIO
IPC: C22C14/00
Filed: 1990-10-12
Abstract: PURPOSE:To provide a formed product with sufficient erosion resistance at a low cost by forming the erosion resistant formed product for handling molten metal of Al, Mg, etc., of titanium or titanium base alloy raw material. CONSTITUTION:The titanium or the titanium base alloy uses the general raw material on a market. In the case of being unnecessary to be high strength, the pure titanium is used, and on the contrary, in the case of being necessary to be the high strength, the high strength titanium represented by 6A1-4V and the balance Ti material is used. These raw materials are entirely unnecessary to execute surface treatment after forming as the parts, and even if this is directly dipped into the molten metal of Al or Mg, etc., or brought into contact with the above molten metal as it is, this displays the sufficient corrosion resistance. As this reason, it is estimated that oxide film is instantaneously formed on surface layer of the titanium as active metal or stabilized by alloying and is not eroded any further.
