Title: Device for recovering heat from exhaust gas
Inventor: MINOWA RYOHEI
IPC: F28F27/00
Filed: 1986-02-26
Abstract: PURPOSE:To prevent the flow of an exhaust gas from being subjected to any trouble even when soots contained in an exhaust gas adhere to a heat exchanger by providing a damper only at an upstream side branch portion among branch portions of a main duct and a bypass duct. CONSTITUTION:A damper is provided at an upstream side branch portion as viewed from the flow of an exhaust gas among branch portions of a main duct 1 and a bypass duct 6. In the case of recovering heat from the exhaust gas, the damper 7 is opened and a fan 8 is started. Then, the exhaust gas 2 is led to the bypass duct 6 and circulates through a heat exchanger 4. Since there is no damper in the main duct 1, when soots adhere to the heat exchanger 4 and the ventilation resistance on the side of the bypass duct 6 becomes large, the exhaust gas 2 spontaneously flows to the main duct 1. Accordingly, an operation of recovering heat from exhaust gas is performed without giving any trouble to a heat source apparatus.

Title: Rotary compressor
Inventor: TAGUCHI TATSUHISA
IPC: F04C28/26
Filed: 1979-04-02
Abstract: PURPOSE: To prevent extraordinay increase in the discharge pressure of coolant gas from a rotary  compressor by providing a bypass circuit arranged inside the cylinder wall of said compressor  which controlls the quantity of the coolant gas in accordance with the temperature of the freezing  cycle and thereby bypassing some of the coolant gas depending of the temperature of the coolant  gas discharged.  
     CONSTITUTION: In the wall of a cylinder 9, there is formed a bypass circuit 19 which extends  between a first space, which is not in communication with a discharging outlet 18 and suction inlet 16, and a second space, which is in communication with either one of discharging outlet 18  and suction inlet 16. The bypass circuit 19 is provided with a regulator 20 containing a high pressure chamber 22. When a compressor 1 is driven and the temperature or pressure in the pressure  chamber 22 has become higher than the repulsive force of a spring 24, a plunger 21 moves away  from the pressure chamber 22 to a position where the repulsive force of the spring 24 and the pressure in the chamber 22 is balanced, resulting in an opening of said bypass circuit 19. The degree  of opening of the bypass circuit 19 varies depending on change in the temperature of the coolant  gas discharged, control the flow rate of said coolant gas through the bypass circuit. Thus, extraordinary compression, and decrease of the suction pressure of the coolant gas, in the compressor  1 can be prevented by controlling the compression amount of the coolant gas depending on the  temperature of the coolant gas discharged.

Abstract: PURPOSE:To suppress the erosion of a tundish stopper as much as possible by controlling a total Ca concentration in molten steel so that the relation between a total Ca concentration and total oxygen concentration meets the specific inequality when molten steel is subjected to Ca treatment and continuous casting. CONSTITUTION:When erosion occurs, the inclusion of composition, which contains high CaO in comparison with the inclusion composition of stabilized casting and has a melting point lower than the casting temp., is caused. To this end, A total Ca concentration in molten steel is controlled so that the relation between a total Ca concentration in molten steel and a total oxygen concentration in molten steel meets the inequality: [Ca]/T[O] <=1.6-0.02XT[O]. Here, [Ca] is Ca concentration in molten steel (ppm), T[O] is oxygen concentration in molten steel (ppm). Thus, T[O] and [Ca]/T express an absolute quantity/ form of each inclusion, in the case that the inclusion in steel is in the same form, an erosion speed of the stopper is controlled by the absolute quantity of inclusion.
