Title: Operating method for converter blowing
Inventor: AOKI MATSUHIDE
IPC: C21C5/28
Filed: 1984-09-18
Abstract: PURPOSE:To decrease the content of N in a molten steel in the blowing-out stage of a converter and to prevent the deterioration in the ductility and toughness of a converter steel by using briquettes having small pressure-resisting strength as the briquettes for heating up in the operating stage of the converter. CONSTITUTION:The briquettes for heating-up are added to the steel and the temp. of the molten steel is increased for the purpose of accelerating decarburization reaction, reducing the cost by the use of a cold charge such as scrap or for making up the deficient heat of the molten iron subjected to a preliminary treatment in the stage of oxygen-blowing a steel in the converter. The lumped briquettes such as coke having <=90kgf pressure-resisting strength are used as the briquettes for heating up to be added into the converter. The carboneous material such as coke having the low pressure-resisting strength collapse in the molten metal and melt quickly into the molten metal. The N2 migrated from the briquettes into the molten metal in the stage of the decarburization reaction by CO boiling is denitrified as well and the content of the N2 in the molten metal in the blowing-out stage of the converter is made lower than the content when the briquettes for heating up having the high pressure-resisting strength are used.

Title: Bipolar transistor cirucit
Inventor: UDOMOTO JIYUNICHI
IPC: H03F3/19
Filed: 1994-08-19
Abstract: PURPOSE: To prevent the destruction of an element by controlling the collector current value of a first bipolar transistor by adjusting the bias current of a second bipolar transistor to a desired value. CONSTITUTION: Bias to be applied to a terminal N7 is set so as to let the collector current value of a transistor 2 be a required limited current value. At the time, the collector current value made to flow to the transistor 2 becomes the upper limit of the collector current value of the transistor 1. Thus, by setting a bias current to be applied to the transistor 2 to a required value, setting is performed so as to limit the maximum value of the collector current of the transistor 1. Then, signals inputted to an input terminal N1 are amplified by the transistor 1 and the one equal to a value for which the amplification factor of the transistor 1 is multiplied with the size of the input signals is made to flow as the collector current. The current made to flow to a collector increases as the size of the input signals increases, however, since the maximum value is limited, the destruction is prevented.

Title: Skew correcting device
Inventor: NAGAHARA OSAMU
IPC: H04N5/95
Filed: 1984-09-20
Abstract: PURPOSE:To prevent the erroneous action of a device by cutting the signal supplied to an integrator from the phase comparator of a PLL loop composed of a phase comparator, integrator and a voltage controlled oscillator at the point when a drop-out compensation circuit detects a drop-out, and supplying the integrated value immediately before the detection. CONSTITUTION:When a drop-out detector 11 detects the drop-out of a reproduction signal, it outputs a detection signal 500 to a monostable multivibrator 13. A PLL control signal 600 outputted from said multivibrator 13 opens a switch 14 so that the output of a phase comparator 4 will not be supplied to an integrator 7. It outputs the integrated value of the signal from the phase comparator 4 immediately before the switch 14 opens to a voltage controlled oscillator 6. At the point when a reproduction head terminates the track jumping and a reproduction signal 50 is restored to be a normal one, the control signal 600 is turned off, and the PLL loop restores to a normal action. Thus the erroneous action of a skew correcting device can be prevented.

Title: Refrigerant gas
Inventor: UMEDA TOSHIKI
IPC: F25B1/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To obtain a refrigerant gas which is used for, e.g. a refrigerator and neither causes ozonosphere depletion nor makes the earth warmer by mixing specified compounds at a specified ratio. SOLUTION: This gas is formed by mixing 40-60wt.% isobutane and 60-40wt.% propane and has a vapor pressure approximate to those of R12 and R134a heretofore used, or it is formed by mixing 90-98wt.% propane and 10-2wt.% ethane and has a vapor pressure approximate to those of R22 and R502. Therefore, it is possible to replace a refrigerant gas without changing the system constitution using a conventional chlorofluorocarbon or hydrofluorocarbon gas. Since the gas has a saturated liquid density and viscosity lower than those of a chlorofluorocarbon or hydrofluorocarbon gas, the mechanical load is reduced when a refrigerant is circulated by a compressor so that the energy efficiency can be improved.
