Title: Method for controlling atmosphere in induction heating furnace
Inventor: SHIROYAMA KENJI
IPC: C21D1/42
Filed: 1993-01-11
Abstract: PURPOSE:To provide an atmosphere control method in an induction heating furnace, in which the generating quantity of dripped scale is reduced and the removal work of the scale can be saved. CONSTITUTION:An oxygen concn. in the furnace is measured, and hydrogen gas is supplied into the furnace so as to satisfy the relation, [hydrogen concn. >=0.5 X oxygen concn.]. As a part of the scale mainly containing FeO+ Fe2SiO4 taken together with a slab in the induction heating furnace is reduced with the hydrogen gas blown as the atmospheric gas in the furnace to change the oxide into Fe, the fluidity of the scale is lowered. Therefore, the molten scale quantity dripped from the slab is reduced and the scale quantity held to the slab is increased.

Title: Flip-flop circuit
Inventor: TAKAHASHI TORU
IPC: H03K3/2897
Filed: 1986-01-30
Abstract: PURPOSE:To obtain a high speed AND logic with respect to plural input data by taking OR logic in a data input section of a slave flip-flop to an inverted output of plural master flip-flops. CONSTITUTION:An input data desired to obtain an AND logic output finally is fed respectively to data input terminals D1, D2 of the 1st and 2nd master flip-flops. The inverted output of the two master flip-flops is inputted to date input transistors (TRs) Q13, Q14 of the slave flip-flop respectively, where the OR logic is executed. Since the TRs are connected in parallel simply and the number of fan-in has only to be increased with respect to the OR logic, no delay time is increased in this circuit part and an AND output of the data is obtained at the inverted output of the slave flip-flop.

IPC: B23K35/02
Filed: 1983-02-10
Abstract: PURPOSE:To obtain welding with good bead appearance by forming a core wire of a gravity welding rod into a hollow shape to decrease the rate of deflection owing to the weight of a holder.

Title: Magnetic fluid recording device
Inventor: IRIE HIROYUKI
IPC: B41J2/06
Filed: 1981-02-12
Abstract: PURPOSE:To obtain on a recording paper high quality images without recording noises by applying recording voltage in pulse to the control electrodes and overlapping the voltage of the opposite polarity by the timing of the end of applying the recording voltage in the method to apply voltage of a magnetic fluid recording device. CONSTITUTION:When opposing control electrodes and stylus electrode of a magnetic fluid recording device are matrix-driven and image signals are continuously applied, the voltage -Vp of a recording paper surface becomes larger to the side of minus as the time passes, and it makes fly the ink from a stylus electrode that is not selected, and thereby the quality of recorded images becomes inferior. The voltage wave shape 16b becomes capable of returning swiftly to the original voltage after the voltage -Vp arrives by overlapping a volgage VA to the control electrode as in the pulse wave shape 15b of the control electrode after applying a recording voltage -VG. With this setup recording noises are eliminated and the quality of recorded images is raised.

IPC: A61M15/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To dose normal amount of medicine powders to a patient by doing grain refinement of medicine powder. SOLUTION: A capsule holder 5 is placed inside the holder storage part 4 of body 2 removably. By an inhaling mouth 16 being installed to the body 2, a mixture room 17 is formed between the front hem side space of body 2 and a taper face part 16A. A passage formation body fixing hole 16B of inhaling mouth 16, which locates on the lower flow side of the mixture room 17, is equipped with a passage formation body 18 that has a swirling flow passage 19. Thus, when a patient breathes in from the inhaling mouth 16 and inhales medicine powder in a capsule K, the air containing medicine powder flows into the mixture room 17 from efflux side ventilation passage 12, 13. The air in the mixture room 17 flows out from the swirling flow passages 19 and forms a swirling flow. This swirling flow promotes doing grain refinement of medicine powder.

Abstract: PURPOSE:To allow the titled transmitter to cope easily with digital display and digital signal processing by using an output of a sample-hold circuit sampling a voltage between terminals of the 1st capacitor connected between the other terminal of a variable current source and the other output terminal with a period longer than the frequency to control an output of the variable power supply thereby eliminating an expensive highly accurate operating resistor. CONSTITUTION:An output current i0 of a variable current source 4 is controlled by a sample-hold voltage Vp as shown in an equation I , where VGS is a gate- source voltage of an FET42 and VBE is a base-emitter voltage of a transistor 41. Since the charging voltage of a capacitor C2 is expressed as Vc2=ic.R7, an average current is per unit time is expressed as an equation II. A change DELTAVp in the sample-hold voltage Vp is expressed as DELTAVp=-DELTAV=T(is-i0)/C1, and a change DELTAi0 in the i0 to the change in the DELTAVp is expressed as an equation IIIwith a transfer function K of the variable current source 4. Then the system is balanced at the next sample period by selecting T or C1 to attain the relation of KT/C1=1.

Title: Circuit constitution protecting input of integrated circuit supplied with voltage from power supply from overvoltage
Inventor: RASUTSURO GOTSUTSU
IPC: H02H9/04
Filed: 1991-02-14
Abstract: PURPOSE: To surely protect an input of integrated circuit, even when a power supply voltage fluctuates or a temperature change occurs by impressing a reference voltage, while connecting the serial circuit of diode and constant current source arranged between a power source and the ground to the other control terminal of four-layered diode. CONSTITUTION: When a protection circuit 10 is formed as one part of integrated circuit, transistors T1 and T3 are prepared under the same conditions and in the same manufacturing stage. As a result, these two transistors have completely equal temperature characteristic. Since the base/emitter voltage of the two transistors depending on voltages exists both between the base of transistor T1 and a terminal 26 on one hand and between that base and a terminal 21 to supply the power supply voltage on the other hand, the response threshold value of the protection circuit is not affected by the temperature change. As a result, the difference between the power supply voltage and the voltage at the terminal 26 is kept constant, in spite of temperature fluctuation.
