Title: Method of recovering thermal energy of exhaust gas from converter
Inventor: FUKUTOME MASAHARU
IPC: C22B1/20
Filed: 1977-12-23
Abstract: PURPOSE: To produce a sintered ore lower in reduction disintegration index and excellent in anti-reduction pulverability by adjusting the conventration of oxygen in a sucked sintering gas in sintering ore for a blast furnace by a Dwight-Lloid sintering machine.  
     CONSTITUTION: An exhaust gas in a wind box 5 located at the ore feeding side of a sintering machine is sucked by a fan 7 and discharged out through a chimney 17. On the other hand, an exhaust gas in a wind box 2, located at the ore delivery side of the sintering machine, with a high temperature, containing a comparatively high amount of oxygen, is introduced into hoods 10 on a strand of the sintering machine via a duct 3, a fan 4 and a duct 8 under the adjustment of flow control valves 12. Air is sucked by a fan 14 and introduced into the hoods 10 through flow control valves 16. The valves 12 and the valves 16 are properly adjusted so that the concentration of oxygen in air passing through a layer of material to be sintered is higher on the ore feeding side than the ore delivery side. With such an arrangement, a sintered ore uniformly excellent in anti-reduction pulverability can be obtained regardless of the position of layer in the sintered ore on the pallet.

Title: On/off door for pressure vessel
Inventor: KAWAHITO AKIYOSHI
IPC: F16J13/22
Filed: 1990-06-14
Abstract: PURPOSE:To enable it to set a door's moving space and a storage space smaller and thereby reduce the cost of production by pressurizing a cavity part of the door at a closing position, pressing a peripheral edge of the door to an interval between opposed surfaces of a support member and an opening circumference, and sealing and closing them. CONSTITUTION:When an opening 1 of a pressure vessel is sealed and closed by a door S, air is supplied to a cavity part 10 of the door S at a closing position via a vent pipe 11, thereby pressurizing the inside of the door S. With this pressurization, the door S expands to some extent, and a peripheral edge of the door S comes to be pressed to an interval between a peripheral edge of the opening 1 of a pressure vessel body A and a support member 2, thus it is relatively tightened. At this time, strength of the door itself and clamping force are increased according to pressurization in the cavity part 10, so that internal pressure in the door S is determined according to that in the pressure vessel. When a sealed state is set free, inversely air in the cavity part 10 is exhausted out of the vent pipe 11, and the door S is contracted. In this connection, air exhaust at this time may be done by dint of resilience of the door S itself and by means of connecting a suction pump or the like to this vent pipe 11 otherwise.

Title: Unbalance correction method of rotary material and its unit
Inventor: KUROUME HIROSHI
IPC: H02K15/16
Filed: 1978-12-21
Abstract: PURPOSE: To improve efficiency of rotary material unbalance correction by changing weight mass in the course of rotation of a rotary material to detect vibration by a vibrometer and obtaining an unbalance correction position and a correction quantity from the vibration characteristic.  
     CONSTITUTION: Two or more balance weights 3 which can change mass by remote control in the course of rotation are fitted to the balance correction face of rotor 1. When the initial vibration value does not satisfy an allowable value, arbitrary gunpower 32 is ignited in the course of rotation of the rotor to break lead plate 33, and steel ball beads 34 are ejected by a centrifugal force to change mass of arbitrary weight 3. The weight influence coefficient in each correction face is calculated by computer 10 on a basis of change of vibration data dependent upon the operation above, and an optimum weight fitting correction face and its mass which can restrain vibration below a prescribed allowable value are calculated from this coefficient automatically. Thus, rotary material unbalance can be corrected efficiently.

IPC: G06F9/48
Filed: 1988-06-24
Abstract: PURPOSE:To improve the execution efficiency of a program without using a general timer and to process the program by providing the title circuit with a 9-bit counter to be cleared by a clear pulse generated at a fixed period and an 8-bit latch for latching the high-order 8 bits of the counter immediately before the clear pulse. CONSTITUTION:The counter (a) is cleared by a reset pulse (c) generated immediately after the writing operation of the latch (b), and at the time of overflowing within 980musec, the 9-bit counter (a) resets its counted value to '0' and stops its counting. At that time, '0' is written in the 8-bit latch (b) and the data written in the latch (b) can be optionally read out by reading out an address allocated to the latch (b). The period of an HSYNC can be easily calculated by the number of HSYNCs counted in a 980 musec period. Consequently, it is unnecessary for a CPU to execute frequent interruption processing for measuring the period of the HSYNCs and the execution efficiency of the program can be improved.
