Title: Digital modulation and transmission system
Inventor: HORIKAWA IZUMI
IPC: H04L25/49
Filed: 1978-02-13
Abstract: PURPOSE: To enable the digital transmission with high quality, by improving the S/N of narrow band interference noise through the use of the code conversion technology and the interference removal filter, in the digital transmission system.  
     CONSTITUTION: The signal pulse train fed to the input terminal 11 is converted into random pulse signal with the transmission logic conversion circuit 12. The signal is restricted with the transmission code conversion circuit 26 to the random binary signal train, and the code conversion A is made so that no spectrum component is included near N/M times the DC component and clock frequency fCL as signal spectrum. The modulator 13 modulates the carrier from the local oscillator 14 in the signal series after code conversion processing, and the high region of the both side and frequency component is removed with the band pass filter 16 from the modulated output and it is transmitted from the terminal 17 as the carrier band spectrum 27 having the center frequency f c  shown in the solid lines of B. The f c  is matched with the center frequency of the interference noise.

Title: Receiving apparatus
Inventor: KIMURA ATSUSHI
IPC: G01D3/02
Filed: 1992-01-30
Abstract: PURPOSE:To improve operability by operating and correcting the deviation between the data, which are fed back from an object to be controlled, and the zero value or the value of a span, which was stored beforehand at the time of shipment, and automatically executing zero/span adjustment. CONSTITUTION:A constant voltage circuit CVR generates the circuit power source by using current signal. The voltage signal corresponding to the current signal is generated in a switch element SW1. The switch element SW1 and a constant current circuit CC are connected in series and form a short-circuit SC1. The voltage signal and the feed-back signal, which is fed back from the object to be controlled, are inputted into an operation amplifier A1. Operation is performed so that these signals agree with each other. The control signal is outputted to the object to be controlled. When the current signal corresponding to a span is inputted, the switch element SW1 is turned on/off. The deviation between the data, which are fed back from the object to be controlled in response to the inputted voltage signal, and the zero value or the value of the span, which was stored beforehand at the shipping time, is operated. The correcting operation for correcting these values are executed.
