Title: Method for melting extra-low carbon steel
Inventor: YOSHIHARA MITSUO
IPC: C21C7/04
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To obtain the decarburization with low oxygen adding quantity which reduces FeO and MnO in slag and obtains little inclusion by adding reducing agent at a specified adding speed into a slag in molten steel refined with a converter and tapped in a ladle and executing the decarburizing and degassing treatment with a vacuum degassing apparatus. SOLUTION: The molten steel refined with the converter and having about 0.03-0.06 C is tapped into the ladle and refined by using the vacuum degassing apparatus to apply the decarburizing and degassing apparatus. At this time, the reducing agent of Al, etc. is added at >=0.1 t/sec adding speed into the slag containing about 20-40% FeO+MnO on the molten steel. In this way, FeO and MnO in the slag are uniformly reduced and FeO+MnO in the slag is reduced to <= about 10%, and also, the reducing of the oxygen quantity is restrained. Thus, the min. quantity of oxygen blowing can be refined and the oxidation of Al, etc. in the molten steel caused by the blowing oxygen and FeO and MnO in the slag, is prevented and a high quality extra-low carbon steel having little non-metallic inclusion and <= about 0.005% C, is obtd.

Title: Data protecting circuit
Inventor: HASHIMOTO MASAMI
IPC: G11C11/407
Filed: 1985-05-15
Abstract: PURPOSE:To obtain an easy-to-handle memory by providing a pulse generating circuit generating an impulsive intermediate potential between power source and a selecting circuit supplying the pulse signal of the pulse generating circuit. CONSTITUTION:When the title circuit is composed of one N-type insulating gate electric field effective type transistor 22 and a capacitor 23, a potential more than the positive potential VDD of the power source is supplied to a word line selected by an address signal 12, while the impulsive signal having the intermediate potential of the power source voltage supplied from the pulse generating circuit 10 is applied to remainder nonselected word lines. Since there is the possibility that data in a memory cell which belongs to the nonselective word line disappears if said state continues for a long period, the elimination of the data in the memory cell is prevented in such a way that the pulse transmitted from the pulse generating circuit is supplied to plural word lines which are not selected by the address signal through the selecting circuit. Thus the system which is easily handled and has substantially little useless time can be built up.

Title: Amplifier
Inventor: TANAKA KUNITSUGU
IPC: H03F1/22
Filed: 1991-05-09
Abstract: PURPOSE:To simplify the circuit constitution and to realize an inexpensive amplifier without need for inserting a band pass filter by dividing a band for a gain into a low frequency and a broad frequency. CONSTITUTION:Desired band split is realized by providing a resonance circuit 21 to a base of a transistor (TR) Q2 of a common base amplifier circuit 2 being a component of the amplifier. A broad band gain frequency characteristic covering low and high frequencies of a band is shown as shown in a curve B through the application of current series feedback and voltage parallel feedback. A resonance circuit 21 whose resonance frequency is set to an intermediate frequency f0 of a band is inserted to the base of the TR Q2. Since the impedance of the resonance circuit 21 is increased in the vicinity of the resonance frequency f0, a gain of the common base amplifier circuit 2 is reduced. On the other hand, since the impedance of the resonance circuit 21 is sufficiently reduced at a low frequency or a high frequency apart from the resonance frequency f0, the gain of the common base amplifier circuit 2 is restored to the substantial gain. Thus, the desired low and high frequency is split into two bands.

Title: Beam heat treating method
Inventor: OTA MASAO
IPC: C21D1/09
Filed: 1987-04-28
Abstract: PURPOSE:To prevent fusion at finishing end part and to uniformly execute heat treatment on the whole surface to be heat-treated by arranging a shielding plate at finishing end part of heat treatment of the material to be processed and directly irradiating high energy beam except the finishing end part. CONSTITUTION:The shielding plate 11 is arranged at the finishing end part 5 of the material 1 to be processed. Quenching treatment is executed in order from the right side by an electron beam 3 having high energy density, but at the starting end part, the material 1 to be processed is not fused because the temp. thereof is not raised. When the quenching treatment progresses and approaches to the finishing end part 5, temp. of the material 1 to be processed is raised by heating before reaching to there. However, as the finishing end part 5 is shielded by the shielding plate 11, direct heating by the electron beam 3 is not executed. In this result, the finishing end part 5 is not fused and raised to the prescribed temp. The temp. of the finishing end part 1 is sufficiently raised to A1 transformation point by only heat conduction. After that, by self- cooling, the uniform hardened layer 2 is formed.

Title: Multivibrator
Inventor: MATSUO KENJI
IPC: H03K3/023
Filed: 1983-06-09
Abstract: PURPOSE:To prevent malfunction of a comparator having a slow operating speed by feeding back an output of an OR circuit to an input of a flip-flop via a delay circuit so as to block the inversion of the flip-flop until a delayed output is given thereto. CONSTITUTION:When a clock signal rises and after the switching time of the comparator CMP is elapsed, an output (b) of an AND gate AND2 goes to ''1'', an output Q goes to ''1'' and an output Q' goes to ''0''. Since an output of an inverter INV2 is fed back to the input of an NAND gate NAND1 and an AND gate AND1 via a delay circuit DL, the level of a terminal Cx given with an output of an NOR gate NOR1 goes to ''0'', causing its output (a) to go to ''1'' via the AND gate AND1 after a delay time of the delay circuit DL, and the outputs Q, Q' are held respectively at levels ''1'' and ''0'' during this time. Then outputs F, F' of the flip-flop FF is inverted respectively.

Title: Remote controlling system
Inventor: ANDOU ISAO
IPC: H04Q9/06
Filed: 1982-06-16
Abstract: PURPOSE:To realize a remote controlling with a simple and small scale circuit, by providing with plural attenuators which attenuate the output of a transmitter for each control, for a controlling station, by transmitting the output of the transmitter through one of lines, and by transmitting the attenuated output through the other line. CONSTITUTION:An attenuators group 29 of a controlling station contains an attenuator 23 of the attenuation amount of 0,1/2,1/4,1/2m and 24-26 which can be selected by switches SW1 and SW2. When controlling a relay 17 of a controlled station NOm, a level generator 20 generates the level of Lm=1/2m X Ls. The controlling station selects the attenuator 26 and sends a signal through a line 22. On the other hand, a level Ls is transmitted to a line 21. A subtractor 11 of the controlled station NOm outputs a difference LR between both of the levels. The difference LR becomes equal to the Lm, a comparator 14 sends a controlling signal to drive the relay 17. Since the level inputted in comparators 12 and 13 of controlled stations NO.1 and NO.2 is equal to the LR, the comparators 12, 13 differ from the level inputted by the level generators 18 and 19 so that the controlling signal is not generated.

Abstract: PURPOSE:To obtain a semiconductor device having small occupying area and high intergration density by providing a semiconductor base material and an insulating layer consisting of an insulator deeply extending in the depth direction at the interface with the well region provided in said base material. CONSTITUTION:An insulating layer 20 is provided at the interface between a Si substrate 1 and a well layer 2. This insulating layer is 5mum or less in width and is deeper than the P type well 2. Moreover this layer separates the P channel MOS transistor and N channel MOS transistor and electrically and alternatively interfering the currrent path of the base region (well 2) of parasitic bipolar transistor and electrode (impurity layer 4) of the base region. As a result, the insulating layer 20 is formed deeper than the well layer 2 and therefore the P type impurity layer 4 and P type well layer 2 are insulated perfectly and noise current which causes latch-up takes a route at least deeper than the depth of well from the sulface and its width is as narrow as 5 um or less. Thereby, transistors can be formed with a shorter interval, resulting in a large advantage for high integration structure.
