Title: Smelting method for metal sulfide mineral
Inventor: GOTOU MITSUO
IPC: C22B5/02
Filed: 1980-12-10
Abstract: PURPOSE: To increase a metal sulfide mineral, etc., without increasing waste gas in amount by eliminating or holding the burning amoung of oil of an auxiliary fuel burner constant in smelting and by varying O 2  concentration of fuel air and the total amount of blown air instead.  
     CONSTITUTION: When a smelting furnace, a converter, etc., are used for continuous operation, the burning amount of oil of an auxiliary fuel burner, O 2  concentration of fuel air, and the total amount of blown air are adjusted in smelting. As a result, the temperature and rugulus quality of a solution are controlled. If the amount of blown air through lance pipes decreases and the reaction rate of the solution is decreased possibly, some of the lance pipes are separated and the amount of the blown air regarding the separated pipes is held constant in smelting. Consequently, the heating rate of the solution in the furnace is increased and the life of the furnace is prolonged.

Title: Internal-combustion engine with supercharger
Inventor: SUZUKI SATOSHI
IPC: F02B33/44
Filed: 1983-09-22
Abstract: PURPOSE:To increase the number of revolution of a turbine with a reduced load applied to a compressor so as to improve the acceleration performance by supplying intake air through a by-pass of the compressor, and almost totally closing a compressor-upstream by means of a control valve during light-load running of the turbine. CONSTITUTION:A intake air path 21 positioned upstream with respect to the compressor 5 of a supercharger is connected to the upstream side of a throttle valve 3 by a by-pass 22, and control valves 23, 24 are interposed in pathes 21, 22 respectively. Those respective control valves 23, 24 can be opened and closed through a linkage by a common actuator 25 which is driven by the negative pressure of intake air. When an engine operates at a range of low speed light- load running, including an engine shutdown, the control valve 23 is totally closed and the control valve 24 is fully opened. Then, the turbine 8 is driven in a state without air flow in the upstream side of the compressor 5 and the number of revolution of the turbine is increased. Thus, if acceleration is effected by stepping on the acclerator, the valve 23 is opened and the valve 24 is closed simultaneously, and a good start up-super-charged pressure can be obtained.

Title: Sum signal generating circuit using josephson effect
Inventor: SONE JIYUNICHI
IPC: G06F7/38
Filed: 1981-10-29
Abstract: PURPOSE:To increase an operation margin and to perform high-speed operation by employing an interferometer gate circuit which uses two Josephson junctions having asymmetric control characteristics to the polarity of an input current. CONSTITUTION:Output currents corresponding to output signals An and Bn flow to output terminals 44 and 45 of interferometer gate circuits 32 and 39 which perform AND operation. In this case, a resistance 46 connecting the output terminals 44 and 45 together has a resistance value much less tan terminal resistances 47 and 48, so if either of gate circuis 32 and 39 has transition to a voltage state, the output current is applied to the other gate circuit through the resistance 46, allowing the gate circuit to have transition to a voltage state. Consequently, gate currents Ig1 of the gate circuits 32 and 39 flow into the terminal resistances 47 and 48 through output lines 49 and 50, so that the exclusive OR signal of input signals An and Bn appears on output lines 49 and 50 as output signals.

Filed: 1983-09-21
Abstract: PURPOSE:To speed up positional adjustment of focused light on a recording medium and attain precise focus adjustment by focusing polarized light on the surface of the recording medium by using the 0-order diffracted light at the diffraction. CONSTITUTION:The 0-order diffracted light 29 and a polarized light 30 projected from a polarizer using an elastic surface wave form an image on the recording medium 27 through a beam splitter 22 and an objective lens 24. The reflected light based upon the polarized light 30 is used for the recording and reproducing of information and the reflected light due to the 0-order diffracted light 29 is guided to a two-divided phtodetector 26 and used for the control of a focus 31. Since the surface of the photodetector 26 has a conjugate relation to the surface of the recording medium 27, focus adjusting signal light is not oscillated on the surface of the detector 26 even if the polarized light is polarized in any direction, so that always precise focus control is attained and the positional adjustment of the fucused light can be speeded up.
