Title: Converter for refining of metal
Inventor: MURAKAMI SHIYOUZOU
IPC: C21C5/35
Filed: 1982-01-09
Abstract: PURPOSE:To provide a converter for refining of metal which eliminates the mutual interference of the stirring energy among tuyeres and improves the stirring force over the entire part of molten steel in tuyeres for blowing of gases for refining under the surface of molten metal by providing >=2 tuyere groups wherein the bores of the tuyeres among the groups differ respectively. CONSTITUTION:In tuyeres under the surface of molten metal in the above-described converter, a number of the tuyeres constituted of a large number thereof are made different in diameters from the ohter tuyeres. As a result, the rates of blowing of gases are varied from each other to generate differences in the stirring forces among the tuyeres and to increase the stirring force over the entire part of molten steel. It is important in this stage that the flow rates of the  respective gases to be blown through the tuyeres are kept without fluctuating  during blowing. For said purpose, opening gates (orifices) smaller than the bores of the tuyeres are provided at the roots of the inside pipes of the respective tuyeres. The opening areas of the orifices are preferably made 80-50% the sectional area of the inside pipes of the tuyeres. The above-mentioned constitution intensifies the stirring of the molten steel and is highly effective in improving the yield of molten steel and extending the life of the furnace.

Title: Control method for surface roughness of steel strip
Inventor: IKEDA NIRO
IPC: B24C5/06
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To exhibit scale removing ability at the maximum even if combination of brush rolls is different by changing the rotating speed of the projector of a shot blast device according to the combination pattern of brush rolls and the cold draft of a cold rolling machine. SOLUTION: At first, cold draft (r) at cold rolling is computed from the base material plate thickness and the product plate thickness of a steel strip. The surface roughness Rmax of the steel strip before required cold rolling for leaving no shot-pattern on the surface of the product after cold rolling is seeked. Next, the rotating speed for obtaining the surface roughness Rmax of the steel strip 1 before required cold rolling is seeked, based on relation between rotating speed of a shot blast device at every grinding pattern A, B, C of previously set brush rolls and the surface roughness after acid pickling. Hereby, shot pattern is always not left on the surface of the steel strip after cold rolling, and the line capacity can be exhibited at the maximum.

Title: Electronic analog clock using multistage reduction wheel train
Inventor: SUZUKI KAZUO
IPC: G04C3/14
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a reduction wheel train by reducing the rotor equivalent inertia of the wheel train by constituting the wheel train in multiple stages. SOLUTION: In a reduction wheel train, a rotor pinion 1a, a sixth wheel pinion 2a, and a fifth wheel pinion 3a are respectively meshed with a sixth wheel gear 2b, a fifth wheel gear 3b, and a fourth wheel gear 4b. The rotor equivalent inertia of wheel train is considered for the section from a rotor 1 to a fourth wheel 4. Since the rotating speeds of wheel gears become faster as going toward the rotor 1, the influences of the wheel gears on the rotor equivalent inertia become larger as going toward the rotor 1. Therefore, when the inertias of the wheel gears nearer to the rotor 1 are reduced, the inertia of the whole wheel train can be reduced. It is effective to reduce the radii of the wheel gears as much as possible, because the radii act on the inertia four-power times as much as its value. Therefore, the size of the sixth wheel gear 2b which is engaged with the rotor pinion 1a is reduced and, at the same time, a fifth wheel 3 is interposed between the sixth wheel gear 2b and the fourth wheel 4 so that the reduction ratio from the rotor to the fourth wheel 4 can become the same as that of the conventional example.

Title: Coulomb blockade device and its manufacture
Inventor: ONO YUKINORI
IPC: H01L29/788
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To realize Coulomb blockade devices of a variety of connection structures which can operate at high temperatures. SOLUTION: A silicon layer 2 on an insulating film 1 is processed into such a shape as to have an extremely thin section 3 of a film of at most 5nm and electrode sections 4, 5 which are thicker than the extremely thin section 3. When this structure is thermal-oxidized, a silicon region in the extremely thin section and silicon regions in the electrode sections shift to the right and the left and in the thickness direction and thereby a silicon region which is narrower and thinner than the silicon region in the extremely thick section is formed in a boundary between the silicon region of the extremely thin section and those of the electrode sections. By this method, a tunner barrier having higher energy than the extremely thin section is formed at each side of the extremely thin section 3 and an electric charge can be confined in the extremely thin section 3.  Thus, a Coulomb brockade device which can operate at high temperatures can be realized.

IPC: H04B1/58
Filed: 1982-01-11
Abstract: PURPOSE:To enable the integration of a circuit, by forming a balance network circuit of a hybrid circuit with a switched capacitor filter and putting a delaying circuit into a transmitting circuit of the 4-wire side to compensate the working delay of said network circuit. CONSTITUTION:The transmitting signals sent from 2-wire sides 10 and 11 are transmitted through a 4-wire side transmitting terminal 12 via a detecting circuit 4, a delaying circuit 51 and a subtractor circuit 5 respectively. The 4-wire side receiving signal supplied through a terminal 9 is fed to the sides 10 and 11 after the 4-wire unbalanced input signal is converted into a 2-wire balanced output signal through an amplifier 1 and output impedances 2 and 3. In this case, the 4-wire side receiving signal is fed to the circuit 5 via a balance network circuit 50 consisting of a switched capacitor filter and an amplifier 8 to give the subtraction and offset to the detouring signals given from the impedances 2 and 3 via the circuits 4 and 51. At the same time, the detouring signal given from the terminal 12 is set at 0 and delivered. The circuit 51 functions to compensate the working time of the circuit 50. The circuit 50 can be converted into an IC since its capacitor is small.

Filed: 1990-01-12
Abstract: PURPOSE: To perform high-speed transfer by providing master and slave subsystems and transferring data through a data line and an address bus corresponding to the mode of a control line. CONSTITUTION: As subsystems, a master 12 and a slave 14 are connected through a computer system bus 10 and the bus 10 is divided into an address signal ADDR, data signal DATA and control signal CTRL. In this case, when the control line CTRL of the bus 10 shows a 1st mode, transfer is executed between the master 12 and the slave 14 through the data line DATA. Besides, in the case of write when the control line shows a 2nd mode, the master 12 sends data to the line DATA but in the case of reading, the slave 14 sends data to the line ADDR. Thus, since the data can be transferred through the lines DATA and ADDR, when additional data are transferred through the line ADDR, high-speed transfer is enabled.
