Title: Inductance circuit
Inventor: SASAKI TAKASHI
IPC: H01F30/00
Filed: 1989-02-10
Abstract: PURPOSE:To reduce the adverse influence caused by permeation of radio wave from the outside by connecting in series a first and a second coils having specified inductance values, and making winding axis directions of the first and the second coils identical on a printed board. CONSTITUTION:A first coil 1 and a second coil 2 have inductance values which are respectively one half of a specified inductance value. Said coils are connected in series and arranged on a printed board. The coils have the same winding axis directions. When the permeation of radio wave from the outside happens, an induction current I1 flows in the coil 1, and an induction current I2 flows in the coil 2. Since the winding axis directions of the coils 1 and 2 are identical with reference to the radio wave, the induction currents I1 and I2 flow in the opposite directions at a point (a). As the result, when the inductance values of the coils 1, 2 are equal, the amplitudes of induction currents I1, I2 become equal and cancel with each other. Thereby, the induction current caused by the permeation of radio wave from the outside is remarkably reduced, and the S/N deterioration of a signal can be prevented.

Title: Parity detecting circuit
Inventor: SASANUMA HIROSHI
IPC: G06F11/10
Filed: 1987-02-12
Abstract: PURPOSE:To easily obtain the parity detecting result with a small circuit scale by using an exclusive OR circuit which applies the serial data input and the output of a temporary memory circuit as inputs and a temporary memory circuit which applies the output of the exclusive OR circuit as an input. CONSTITUTION:An exclusive OR circuit 102 calculates the initial value 0 of the output 105 of a latch 103 as well as the latched data. Then the output 1 of the circuit 102 is temporarily stored in the latch 103 by a clock obtained by inverting the clock input. When the output 105 of the latch 103 is stabilized to '1', two pieces of inputs 104 and 105 of the circuit 10 are set to '1'. Thus the output of the circuit 102 is changed to '0'. Then a 2nd bit 0 of a serial data input 100 is latched by a 1st bit of a shift register 101. Thus the output 104 is changed to '0', therefore the output of the circuit 102 is changed again to '1' to be stored temporarily in the latch 103. Hereafter, the exclusive OR arithmetic operations are carried out in the same way. Then the data stored temporarily by the latch 103 can be obtained at the 9th clock as the parity checking result.

Filed: 1982-03-01
Abstract: PURPOSE:To suppress the increase of demodulated distortion even at wide sampling timing intervals, by processing the sampling interval after interpolation in  a demodulation circuit with sampling processing. CONSTITUTION:An output of an LPF in the sampling timing is stored at a register 22, an output of the LPF before one sampling timing is stored in a register circuit 23, and a difference Ta is obtained at an output of a subtractor 24. A value of DELTAS=Ta/4 (in case of interpolation of each sampling timing at four equal intervals) is obtained by a divider 25. The content of the circuit 23 is stored in a register circuit 28 through a signal switching device 27 before the interpolation. The value of DELTAS is added to the content of the circuit 28 at an adder 26 at each timing of interpolation. The output of the circuit 28 is given to an amplitude comparator 29 and a demodulated output signal 30 is obtained. In this case, the maximum value of the demodulation distortion is equal to the time interval of the interpolation timing, e.g., 1/4 of the time interval of the sampling timing, allowing to improve the demodulation distortion remarkably.

Abstract: PURPOSE:To prevent a dead lock and to decrease a buffer for repeating data by determining the priority of data transmission on the address of a node including priority information determined in advance, and the presence and absence of the repeating data in the node. CONSTITUTION:When the data are mutually transmitted between adjacent nodes 1a and 1b, the respective nodes 1a and 1b determine the priority based on the address of the nodes 1a and 1b, which include the priority information determined in advance, and the presence and absence of the data to be repeated in the nodes 1a and 1b.
