Title: Detecting circuit of synchronizing code
Inventor: UMEDA YOSHIAKI
IPC: H04L7/04
Filed: 1982-03-29
Abstract: PURPOSE:To operate a circuit stably with a simple constitution, by writing data, which corresponds to the Hamming distance between a synchronizing code and an input signal, in each address of an ROM and inputting the input signal as an address to this ROM to read out said data as a synchronizing code detection signal. CONSTITUTION:An input signal (i) including the synchronizing code is given to a shift register 2 in serial through an input terminal 1 bit by bit. The parallel output of the shift register 2 is supplied as an address input signal of an ROM 13. Data is written in the ROM13 so that data corresponding to the address of the ROM13 becomes ''1'' when the Hamming distance between individual states, which the signal stored in the shift register 2 can take, and the synchronizing code is shorter than L and said data becomes ''0'' when the Hamming distance is equal to or longer than L. Output data (d) of the ROM13 is taken out through an output terminal 4 to detect the synchronizing code with allowable bit error number L-1.

Title: Receiving filter circuit
Inventor: HIRAYAMA KOICHI
IPC: H04L27/22
Filed: 1988-03-08
Abstract: PURPOSE:To obtain a satisfactory characteristic by subtracting digital data, in which a four-phase modulation is executed, and data, in which the data are delayed for the period of a transmission bit rate. CONSTITUTION:For the digital data to be received, a band limit characteristic is cosine-roll-off-spectrum-equalized, and simultaneously, a carrier frequency is QPSK-modulated by N/2 (N is arbitrary odd number)-fold that of a transmission bit rate frequency fb. The digital data supplied to an input terminal 11 are supplied to the input terminal of one side of a subtracting circuit 12, simultaneously, delayed for one period (1/fb) of the transmission bit rate by a 1/fb delaying circuit 13, and supplied to the input terminal of the other side of the subtracting circuit 12, and the output of the subtracting circuit 12 is extracted through a 1/2 limiting circuit 14 from an output terminal 15. Thus, a filter characteristic corresponding to a full cosine roll-off characteristic can be obtained with a simple constitution and, moreover, without executing a group delay compensation.

Filed: 1982-03-30
Abstract: PURPOSE:To accomplish a high-frequency operation using a simple driving circuit by a method wherein a cathodic driving current, having a quick rising speed and a large peak value, is supplied from the main circuit. CONSTITUTION:When a base current is supplied to a transistor Q1 from a control circuit 3, said transistor Q1 is turned ON, a voltage is induced on the windings n4 and n5 of a base driving transformer TB, and a transistor QM is turned ON. As a result, a current runs on windings n1 and n2. When the base current supplied to the transistor Q1 from the control circuit 3 is broken, the transistors Q1 and Q2 are turned ON. An inverse base current runs to a transistor QM by the turned-ON transistor Q2. A cathodic base current sustaining circuit 10 supplies a sustained current at the described time constant when the transistor QM is turned OFF.

Further, the discharge electrode 13 at least in its spark discharge part 13' is made of a thin plate less than 1mm.. Thus, the less the thickness of the spark discharge part 13' is, the more the field intensity upon the application of electrical voltage may be increased, and as well the number of initial discharge electrons upon the spark discharge is increased due to the temperature rise of the discharge part in the discharge electrode 13 caused by the generated heat, thereby noise current may be decreased. Further, filtering effect due to the resistor 12 also reduces the current noise.
