Abstract: PURPOSE:To quicken reducing reaction of ore to metal state, by separating oxide ore to be supplied to melting and reduction furnace to lump and powdery ores by a suitable ratio, adding the former and the latter from upper part and to a molten metal or a slag respectively. CONSTITUTION:In melting and reduction furnace composed of a vertical furnace part 1 and a vessel part 2, oxide ore is melted and reduced due mainly to interface reaction between the molten metal 8 and the slag 9, and the obtd. metal 8 is discharged through a tap hole 12. In the method, the oxide ore is separated to lump and powdery ores, further added under the ratio of 50:50-90:1. Further the lump ore is thrown from above the furnace through a lump substance throwing unit 6 providing a screw feeder 6a and stayed for a long period at the interface between the metal 8 and the slag 9.

Title: Step motor device
Inventor: IIBU GERE
IPC: H02K16/02
Filed: 1983-04-20
Abstract: The motor unit comprises a stator, two independent rotors having each a permanent magnet located in a cylindrical space defined by three pole faces of the stator, two windings and at least a positioning magnet for holding both rotors, in the absence of current in the windings, in a position in which the magnetic axes of their magnets are each coincident with a rest axis. The field produced by the flow of a current in one of the windings is always at an obtuse angle to one of the rest axes and at an acute angle to the other. The two rotors perform steps of 360 DEG  independently of each other in response to pairs of current pulses, the first of which is applied to one of the windings and the second of which is applied to the other winding. The direction of the current pulses determines which of the rotors performs a step, and the order in which the current pulses are applied to the windings determines the direction of rotation of that rotor. The motor unit can be used in particular in an electronic timepiece.

Filed: 1988-03-22
Abstract: PURPOSE:To make it possible to secure a high dielectric breakdown strength to the pulse voltage and to make the connection shorter by providing a thin semiconductive layer to contact to an auxiliary conductor exposing part and a main conductor connection of a low surge impedance conductor to connect. CONSTITUTION:The connection of a low surge impedance conductor has a semiconductive layer 22 to contact to an auxiliary conductor exposing part 21 and a main conductor connection 13 of a low surge impedance conductor to connect. As a result, even when a large potential difference is generated instantly between a main conductor 1 and an auxiliary conductor 3, the potential difference is divided evenly in the longitudinal direction by the resistance of the semiconductive layer 22, generating no large potential gradient immediately above the main conductor 1 accordingly, and the dielectric breakdown value by the impulse voltage is increased compared in the case of no semiconductive layer 22. Therefore, the connection can be made shorter. And since only a thin semiconductive layer 22 is provided, an increase of the outer diameter is very little, and the flexibility of the connection is not be lost.

Filed: 1987-03-24
Abstract: PURPOSE:To securely generate a resetting signal without being influenced by the rise characteristic of a power source voltage by connecting in a multistage and cascade way a resistance load type source ground circuit stage and a capacity load type source ground circuit. CONSTITUTION:Transistors Tr1, 3 and 2 for driving of respective stages are respectively of an enhancement form and have a threshold value voltage. By connecting the drain of a Tr1 and a gate, the rise of the output contact voltage of a source grounding circuit 51 is delayed compared with the rise a power source voltage Vdd. An output contact (a) starts the voltage rise after the power source voltage exceeds the threshold voltage. In the same way, at an output point (b) of a source grounding circuit 52, the rise is delayed by the threshold voltage of Tr1 and Tr3 only. The rise of the output voltage of an output contact (c) of a source grounding circuit 53 is delayed only by the time constant of the integrating circuit composed of the sum of the delaying of respective threshold voltages of Tr1 and 3, Tr2 and a capacity 8. The output voltage of the circuit 53 is inputted to a Schmidt trigger and converted to binary information having hysteresis.
