Title: Absence transfer registration release system
Inventor: UECHI KOUJIROU
IPC: H04M3/54
Filed: 1992-07-20
Abstract: PURPOSE:To automatically release the registration of an absence trasfer service even when the release is forgotten after the registration of the absence trasfer service. CONSTITUTION:For example, a CPU 8 compares the contents of the addresses of the STA 1 of an MA 91 and an MB 92, and compares the contents of the addresses of the STA 1 of an MC 93 and an MD 94, in each 5 minutes. Then, when a passing time value in the MA 91 is beyond a time threshold value (two hours) in the MB 92, the CPU 8 clears the contents of the MA 91 and MC 93. And also, when the passing time value is not beyond the time threshold value at the time of comparison, the CPU 8 continues the reload of the content of the MA 91. When the passing time in the MA 91 is within two hours, and the number of times of transmission in the MC 93 is beyond a number of time threshold value (5 times) in the MD 94, the CPU 8 clears the entire contents of the addresses of the STA 1 of the MA 91, MB 92, MC 93, and MD 94, and automatically releases the registration of the absence trasfer service by the STA 1.

Filed: 1989-07-26
Abstract: PURPOSE:To obtain an excellent image whether a temperature is high or low by connecting 1st and 2nd gate electrodes to 1st and 2nd scanning signal lines which are provided to every picture element train. CONSTITUTION:The 1st and the 2nd scanning signal lines GL1 and GL2 are provided to every picture element train and the 1st and the 2nd gate electrodes GT1 and GT2 are connected to the 1st and the 2nd signal lines GL1 and GL2. Therefore, the ratio of the channel width to the channel length of a thin film transistor gets large at the time of transmitting a scanning signal to the 1st and the 2nd signal lines GL1 and GL2, so that faulty write in a picture element electrode does not occur by transmitting the scanning signal to the 1st and the 2nd signal lines GL1 and GL2 when the temperature is low. Meanwhile, the ratio of the channel width to the channel length of the thin film transistor gets small and dropping quantity of a video signal caused by parasitic capacity becomes small at the time of transmitting the scanning signal only to the 1st signal line GL1, so that the unevenness of black does not occur by transmitting the scanning signal only to the 1st video signal line GL1 when the temperature is high. Thus, the excellent image is obtained whether the temperature is high or low.

IPC: C21C7/10
Filed: 1989-07-27
Abstract: PURPOSE:To stably carry out the decarburizing refining of a molten steel to a dead-soft carbon region without forming a mushroom at a blowing opening by blowing an O2-containing inert gas into a molten low carbon steel in a vacuum tank in the latter stage in a refining period at the time of subjecting a molten steel to decarburizing refining by means of an RH-type vacuum degassing refining apparatus. CONSTITUTION:A molten steel 3 in a ladle 2 in an RH-type vacuum degassing apparatus 10 is sucked into a vacuum tank and decarburized by the reaction between [C] and [O] in the molten steel, and the resulting gas composed principally of CO is discharged by means of a duct 30. At this time, the flow rate of exhaust gas and CO content are measured by means of a flowmeter 34 and an analyzer 35, and the resulting values are inputted to a process computer 36 to calculate the amount of CO generated. When C content in the molten steel 3 is reduced in the latter stage in a decarburizing refining period and the amount of CO formed by the reaction between [C] and [O], O2 gas to be allowed to react with [C] is supplied by blowing an Ar gas containing O2 gas by 2-20vol.% from a gas supply source 37 through a nozzle tip 46 in a gas-blowing pipe 40 in a state of fine bubbles into the molten steel to accelerate decarburizing reaction, by which decarburization is carried out until a dead-soft carbon grade of <0.003% C is reached and also a mushroom formed at the nozzle tip 46 is melted by the quantity of heat of oxidation reaction by O2 and removed.
