Title: Current detector
Inventor: ISHIGAMI YOSHIHISA
IPC: G01R15/18
Filed: 1982-07-15
Abstract: PURPOSE:To obtain a duty detection output stably even when the magnetic characteristics of a saturable reactor vary. CONSTITUTION:A magnetic multivibrator circuit 21 oscillates invariably at a period T=4.n.phim/Ec, where Ec is a coil impressed voltage and phim is saturated magnetic flux. When the polarity of a primary current flowing through a primary coil 32 is equal direction to that of a secondary current flowing through a secondary coil 33 by the primary coil 32, the secondary current decreases and a tertiary current flowing through a tertiary coil 32 increases to the contrary. A connection point 37 is connected to a common emitter transistor (TR) 53 through the resistance 52 of a duty detecting circuit 23, and a DC voltage Vcc is impressed to the collector of the TR53 through a resistance 54. The DC voltage Vcc is divided by resistances 58 and 59 to apply an optionally set discrimination level V1 to the other input of a comparator 60, whose output based upon the discrimination level V1 is supplied to a driven device 26 through resistances 61 and 62. The DC voltage Vcc is divided by resistances 63 and 64 to apply an optionally set discrimination level V2 to the other input of a comparator 65. The output of the comparator 65 based upon the discrimination level V2 is supplied to the driven device 26 through resistances 66 and 62.

Title: Magnetic card reading method
Inventor: SUGANO KUNIHIRO
IPC: G11B19/02
Filed: 1992-04-17
Abstract: PURPOSE:To provide a highly reliable reading even though there exists a carrier speed fluctuation and a bit omission by deciding a timing based on the time duration between two continuous clock bits and reading each track information based on the timing. CONSTITUTION:A magnetic card CD is carried along a carrying route L and the magnetic information read by a magnetic head 1 is transformed to electrical signals by a transforming section 10. At that time, the sampling timing is decided based on the time duration between two continuous clock bit signals and the recorded information of each track of the card CD is read at this timing. Therefore, the recorded information is always read at an optimum sampling timing based on the current carrier speed. Moreover, when a clock bit is omitted, a sampling pulse, which corresponds to the omitted clock bit, is generated based on the latest time duration, which is already obtained, so as to compensate for the omission of a clock bit.

Filed: 1989-05-19
Abstract: PURPOSE:To always enable stable and correct identification by using the phase frequency detecting circuit of a satisfactory noise resistance characteristic and setting a circuit so that the detection efficiency of a detector can be maximum even when a lot of noises are included in a burst signal such as at the time of a weak electric field, etc. CONSTITUTION:Considering a case that a lot of the noises are included in the burst signal, the collector resistance of transistors Q3 and Q5 in a phase frequency detecting circuit 2 is divided into R1 and R2. The resistance R1 and R2 is set so that the relation of a base voltage between transistors Q11 and Q12 in a detector 3 of a rear step can obtain the potential of an output terminal B in the condition of VP>>VN even when a lot of the noises are included in the burst signal, namely, the detection efficiency of the detector 3 can be maximum. Thus, a stable identified result can be outputted even in such a case and a color demodulating circuit and a color synchronizing circuit can be always operated in a correct state.

Title: Normalizing circuit
Inventor: KUROSAKI NATSUME
IPC: G06F5/01
Filed: 1985-06-07
Abstract: PURPOSE:To perform the normalization processing in a certain short time by providing a barrel shifter, a barrel shifter control circuit, and a detecting circuit which takes partial data of the output of the barrel shifter as the input and detects whether there is an effective bit in this data or not. CONSTITUTION:Data stored in a register 30 is shifted lefted in a barrel shifter 33 by the value of a shift register 32. If there is an effective bit in overflowed data as the result of shift, a detecting circuit 34 outputs NBOV=0; but otherise, the circuit 34 outputs NBOV=1. NBOV is an enable signal of the register 30 in the next cycle, and bits b15-b0 resulting from shift are stored in the register 30 in case of NBOV=1, namely, the absence of the effective bit as the result of shift. Input data is shifted left by 8 bits, and data before shift is shifted left by 4 bits in case of NBOV=0 but data after shift is shifted left by 4 bits in case of NBOV=1, and the number of bits of shift is changed to 8, 4, 2, and 1 hereafter to repeat this operation 4 times, and thus, a value (e) is stored in a shift register 31.
