Abstract: PURPOSE:To secure the strength of a tundish and to facilitate the check of insulating condition by arranging an insulating slit in an iron shell interlinkaging with magnetic flux of an iron core for induction heating in an intermediate channel type induction heating device and making slit duplication and insulation at one position. CONSTITUTION:The insulated tundish for continuous casting is constituted by combining a molten meal receiving part and a molten metal discharging part with plural hollow refractories 4.

Title: A/d converter
Inventor: OGASAWARA KAZUO
IPC: H03M1/12
Filed: 1988-09-22
Abstract: PURPOSE:To minimize the effect of power noise caused from a large scale control circuit by detecting and storing a clock delay minimizing in-band noise power of an A/D converter at application or power or a reset signal and starting the operation after through a reset period. CONSTITUTION:A clock delay minimizing in-band noise power is obtained and stored during the reset period and a delay of a clock supply circuit is set to a stored value through the control of a control circuit 8. An output 36 of an inverter 35 goes to an L level after being at an H level for a prescribed period at application of power. An output of a power detection circuit and an external reset signal are ORed and the result is inputted to a reset terminal to allow the AD converter to start the normal operation after through the reset period at application of both the external reset signal and power. Thus, the S/N of the A/D converter is effectively improved.

Title: Noise fm signal generation circuit
Inventor: KATSUURA HIDEFUMI
IPC: H03B29/00
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce noise FM width fluctuation against a wide range of ambient temperature by preparing a pseudo noise generation means which generates a noise voltage of a pseudo Gaussian distribution based on a clock. SOLUTION: A pseudo random generation circuit 11 generate the random signals in synchronism with the clock sent from a clock generation circuit 10 and converts the random signals into a pseudo Gaussian distribution via a ROM 12. The output of the ROM 12 is converted into a voltage signal by a D/A converter(DAC) 13 and added to the control voltage received from a central frequency setting circuit 6 by an adder circuit 7. This addition signal is used as the control signal of a voltage control oscillator(VCO) 9 which produces a noise FM signal based on the control signal. Thus, the pseudo noises are generated by a digital circuit not by the thermal noises and accordingly the amplitude fluctuation due to the ambient temperature is reduced and the generated noise signal has a high level.  As a result, a stable noise FM signal generation circuit is obtained without increasing the signal amplification factor.
