To provide a transmission apparatus capable of setting the same control data to the entire child transmission apparatuses instantaneously at a time, thereby leading to improved maintenance operation and bringing about efficient maintenance and system stability. The MES system can maintain activity sets representing industry-specific workflows that can be selected and executed in order to satisfy business-driven goals. The multilayer is secured to a first securement adjacent to the leading edge. and based on the speed of sound and the temperature, and correcting the overall mass flow to obtain the mass flow of the first gas. The invention also relates to the use of the sleeve composition to prepare sleeves, the sleeves prepared with the sleeve compositions, and the use of the sleeves to prepare metal castings.
