Abstract: PURPOSE: To maintain high efficiency even when auxiliary fuel is used, by switching an inert gas substitution device, a gas analyzer and a fuel/air selector device  equipped in the gas fuel system, over to the air supply system when the main fuel is lacking.  
     CONSTITUTION: When the plant is lacking of fuel, switching from the gas fuel over to aux. fuel shall be conducted. The aux. fuel is so arranged that its rate of flow is proportional to the valve lift, and the rate of flow of the gas fuel is calculated from the pressure ratio, rotation ratio and number of revolution of a gas compressor 5 and controlled by a by-pass valve 15. When transfer to aux. fuel is completed, a gas fuel shutoff valve 14 and a fuel intake shutoff valve 33 are fully opened in order to open the pressure equalizer valve 35 fully. From this state, for the sake of safety, the line including the gas compressor 5 is substituted once with inert gas, and then switching to the air line shall be made. The inert gas is mixed in the gas fuel when the gas shutoff valve 28a is opened, and, at the same time, the gas fuel is released off of the system through a pressure regulator valve 24 adjusted previously.

Title: Heat sink for semiconductor element
Inventor: NISHIMURA TAKAYUKI
IPC: B23K1/00
Filed: 1989-04-03
Abstract: PURPOSE:To obtain a heat sink which can elongate the life of an element by forming semiconductor super-lattice layers or two or more kinds of metallic thin film layers on the fused and bonded surface of the element. CONSTITUTION:Semiconductor upper-lattice layers or two or more kinds of metal thin film layers are provided on the fused and bonded surface of an element.

Therefore stress generated in fusing and bonding is absorbed. Thus, introduction of dislocation in current conduction can be prevented, and the life of the element can be elongated.
