Title: Amplifying circuit
Inventor: KAMIMURA TAKUZOU
IPC: H03F3/68
Filed: 1981-07-14
Abstract: PURPOSE:To facilitate the synthesis of two input signals by directly inputting two input signals, such as a left and a right stereophonic signal, and imposing BTL amplification on them. CONSTITUTION:A BTL amplifying circuit 20 is equipped with a phase inverter 22 and power amplifiers 24 and 26. The phase inverter 22 supplied with a stereophonic signal R from an input terminal 28A inverts the phase of the input signal and its output is amplified by the amplifier 24, whose output appears at an output terminal 30A. A stereophonic signal L supplied to an input terminal 28B, on the other hand, is amplified directly by the amplifier 26, whose output appars at an output terminal 30B. Then, a speaker 32 as a load connected between  those output terminals is driven by the composite signals of the outputs of the  amplifiers 24 and 26. Thus, those two input signals are synthesized easily.

Abstract: PURPOSE:To improve durability by using a Co-X as a target and subjecting the target to vapor deposition by sputtering by a glow discharge gas contg. <=10% gaseous hydrocarbon in a discharge gas, then forming a hard diamond- like carbon film. CONSTITUTION:The Co-X (X is any among Cr, Mo, W, and Ti) is used as the target and after the target is subjected to the vapor deposition by sputtering by the glow discharge contg. <=10% gaseous hydrocarbon in the discharge gas, the hard diamond-like carbon film is formed. Since the carbon is contained in the surface segregated part of the sputtered Co-X film, the adhesiveness to the hard diamond-like carbon film is greatly improved and, therefore, the thickness as the protective film can be reduced. In addition, the gaseous hydrogen generated at the time of discharge cracking of the hydrocarbon improves the crystal orientational property of the Co-X and, therefore, the short wavelength output is increased and the durability is improved.

Title: Motor control system
Inventor: KOSUGI TATSUHIKO
IPC: H02P6/06
Filed: 1991-05-16
Abstract: PURPOSE:To reduce noise of a DC motor by providing both ends with drive signals instead of bringing drive pulses to the middle of the interior of one phase and by adding micropulses upon a change of drive pulse signal from off to on or from on to off. CONSTITUTION:The control part 2 of a MPU 5 generates drive signals for twice controls on and off of coil current in each coil switch phase. That is, a usual fundamental frequency of 1740Hz can be changed double to 3480Hz, so that noise is reduced with the fundamental frequency kept away from an audible range. The control part 2 of the MPU 5 adds micropulses of slight time width to zones inside each phase where a pulse waveform changes from on to off and from off to on every coil switch phase. Then, a current waveform becomes smooth by synthesization with the result that noise components due to a steep rise and fall decreases. This process can reduce noise of a DC motor 1 due to a fundamental frequency present in an audible band.

Filed: 1980-08-15
Abstract: PURPOSE:To decrease the bubble volume in an ingot after solidification by introducing heated air or inert gas into the space right above the molten metal surface in a mold. CONSTITUTION:Molten steel flow 4 from a tundish 3 drops into the mold space of a rotary ring type continuous casting machine formed of, for example, a copper made rotary ring 1 and a mild steel belt 2, thereby forming a molten metal surface 5 and an ingot 6. At this time, the air or inert gas heated with a heat exchanger 12 is introduced into the sealed space 9 between the mold and a nozzle 7 by a fan 11 via a stainless steel made flexible hose 13. It is desirable to keep the temp. of the air or inert gas higher than that of the molten metal. In this way, the entry of the outside air is prevented by maintaining the part of the atmosphere above the molten metal surface 5 under positive pressure.
