Patent JP-H057132-A (JP)
Title: Automatic frequency control circuit
Inventor: YASUDA ISAKU
IPC: H04B7/12
Filed: 1991-06-27
Abstract: PURPOSE:To attain AFC even when a receiver frequency offset is in excess of a pull-in range of the AFC by detecting the increase in the reception frequency offset so as to revise automatically the frequency of a pilot signal set to the receiver. CONSTITUTION:A frequency of a signal inputted to a receiver is mixed with a frequency of a signal from a VCO 2, the result is subjected to band limit and the result is compared with a reference signal and an error signal is outputted from a comparator 5. The error signal is digital-converted by an A/D converter 6 and fed to a logic circuit 7. The logic circuit 7 generates a control signal for the VCO 2 in response to the digital signal and a D/A converter 8 converts the signal into an analog signal, which is inputted to the VCO 2. When the frequency fluctuation of the VCO 2 is larger and is close to a pull-in range of the AFC, the logic circuit 7 gives a control signal to a frequency converter 9 so as to reduce the frequency fluctuation of the VCO 2. As a result, since the input frequency to the AFC circuit is changed, even when a reception frequency offset of the pilot signal is in excess of the pull-in range of AFC, the application of AFC is attained.

Title: Device for casting thin sheet
Inventor: YASUDA KAZUMI
IPC: B22D11/06
Filed: 1985-07-16
Abstract: PURPOSE:To obtain a thin sheet having an excellent surface characteristic and uniform thickness by providing a rear stationary gate and movable side gate for inclining a casting direction so as to raise and forming a pouring basin for a molten metal on a metallic belt. CONSTITUTION:The metallic belt 1 is driven by a pulley 2 and the side gate 4 is also driven in synchronization with the belt 1. The molten metal is poured from a pouring device 6 into the space formed by the rear stationary gate 5 and the movable side gate 4 on the surface of the inclined belt 1 to form the pouring basin 8. The rear surface of the belt 1 is cooled with water by a cooler 3 in the process of casting which begins from the gate 5. The solidification starts on the surface of the belt 1 past the bottom surface of the gate 5 in the lower part of the basin 8. A solidified layer develops under the molten metal surface and is extracted diagonally upward as a thin sheet. The solidification starts right after the gate 5 on the belt 1 surface. The solidification initiation point is thus made uniform and the formation of cold shut and double surfaces, the ununiform thickness of the solidified layer, etc. arising from the ununiform solidification start point are prevented.
