Title: Method of recovering energy from steam
Inventor: AKUTA TOMOHIKO
IPC: F01K7/00
Filed: 1979-04-06
Abstract: PURPOSE: To recover the energy possessed by low-pressure waste steam at a high efficiency, by increasing the heat drop in a turbine through generation of high vacuum in a condensating injector.  
     CONSTITUTION: A part of steam generated by a proper apparatus is carried through pipe 2 to turbine 4 and causes rotation of generator 5 by effecting work of the turbine 4. Then, it is discharged to pipe 7. Another part of steam is carried via pipe 3 into condensating injector 6 and evacuates section A, so that vapor in the pipe 7 is drawn into section A. Thus, the steam from pipe 3 and that from pipe 7 are carried together to section B, where it is condensed through mixing with cooling water carried to the injector 6 via pipe 9 by feed water pump 8. Pressure of the condensed water is raised since condensation shock waves are produced at section C, and then water is discharged to pipe 11. With such an arrangement, a great heat drop is produced by the difference in enthalpy of turbine steam and that of steam to vacuum, so that turbine efficiency can be improved considerably.

IPC: B23D51/04
Filed: 1988-02-26
Abstract: PURPOSE:To miniaturize a device and lower a cost as well as noise force by operating a table driving cylinder by means of a control cylinder which is driven by a servomotor. CONSTITUTION:As the piston 16 of a control cylinder 10 is advanced via a feed screw mechanism by driving a servomotor 28, the oil pressure of a table driving cylinder 90 which is connected to the control cylinder 10 by means of an oil passage 94 is increased. This oil pressure is detected by a pressure detector 96 and the detected signal is inputted into a controller 98. Based on this signal, the controller 98 controls the servomotor 28 so as to make the oil pressure a defined value. Hence, if a defined program is previously set in the controller 98, cutting can be carried out according to the defined condition. By such a structure, the device can be miniaturized as compared to the case of using a hydraulic unit while also lowering a cost and further, noise can be lowered since there is no pump sound, etc.

CONSTITUTION:An interval timer circuit 12 of a timer control part TMC5 produces reference signals synchronous with 10ms, 1s and 1min respectively. The interval timers of 10ms and 1s have time-out, and Q1 and Q2 output signals of an REG1 are set at ''1''. Under such conditions, the TMRNG signal and the Q1 output signal of a DEC15 are set at ''1''. Therefore the output signal of an AND gate G4 is set at ''1'' and effective to a timer control word TCW. This shows that an interval timer has time-out. In this case, the TCWs of a time range ''01'' (10ms) or ''10'' (1s) within the TMC5 are regarded as the sujects for timer replacement. Then -1 is fed to the timer value.

Title: Degassing device with level detecting mechanism
Inventor: MORITA KENICHI
IPC: C21C7/10
Filed: 1981-03-20
Abstract: PURPOSE:To completely prevent the occurrence of unexpected accident as well as smoothen the degassing of molten steel by providing a level detector for molten steel which is capable of detecting the level from the flow rate value of inert gas to be injected into molten steel in ladle to a degassing device for a suction type vacuum refining method. CONSTITUTION:When a degassing tank 3 goes down (or a ladle 1 goes up) and a suction pipe 4 is dipped in molten steel 2 in the ladle 1, the tip opening 7a of an inert gas supply pipe 7 is also dipped in the molten steel concurrently, whereupon the flow rate of gas in the pipe 7 is reduced due to back pressure loading entailed. The condition is detected by a flow rate detector 8, and the level of molten steel is detected by a device 9 on a conversion basis. Thus, a flow rate value range in a molten steel level such that the circulating flow of molten steel between the tank 3 and the ladle 1 can be made most properly is preset. And, the elevator of the tank 3, or the dipping depth of the pipe 4 in the molten steel 2, is controlled in connection with the flow rate value range, Thus, unexpected accidents, such as the separation of the pipe 4 from the molten steel level when the tank 3 is lifted to too high level during the vacuum suction operation, accident resulting from too sharrow of the dipping depth, etc., can be completely prevented.
