Abstract: Provided are an alloy powder having excellent environmental resistance even in an environment where corrosion and wear are active simultaneously, and an alloy coating using the powder. A Ni—Fe base alloy powder comprising Cr of 15% by mass or more and 35% by mass or less, Fe of 10% by mass or more and 50% by mass or less, Mo of 0% by mass or more and 5% by mass or less, Si of 0.3% by mass or more and 2% by mass or less, C of 0.3% by mass or more and 0.9% by mass or less, B of 4% by mass or more and 7% by mass or less, and a balance of Ni and incidental impurities.

Abstract: A transport stream demultiplexer which receives transport stream packets and outputs data included the packets, has functions of judging whether a received transport stream packet is a null packet, and, if the received transport stream packet is a null packet, prohibiting writing data included in the received transport stream packet thereinto.
