IPC: G11B5/455
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect abnormality of an MR(magneto- resistance effect) head before it enters a fatal state by securely detecting Barkhausen noise. SOLUTION: An amplitude comparator 6 in a servo signal amplitude variation detecting circuit 10 monitors the amplitude of a reproduced signal which is reproduced by the MR head, amplified by a head amplifier circuit 3, and adjusted by an AGC circuit 4 to a constant amplitude and outputs a pulse when the amplitude exits from the range between positive and negative threshold levels TH and TH'. A gate array 7 detects a servo signal from the output of the AGC circuit 4 and outputs a gate signal 71 which becomes true only in a period corresponding to an address part according to the detection timing. A gate 9 outputs the pulse outputted from the amplitude comparator 6 when the gate signal 71 is true as a detection pulse 91 to a CPU 11. The CPU 11 totalizes the frequency of the detection pulse 91 and decides whether or not the MR head 2 is abnormal according to the totalization result.

Further, a head drive circuit 62 drives the heat sensing element group in a thermal head 8 while dividing the group into for blocks in response to a signal outputted from output terminals Q0, Q2, Q4, Q6 of a shift circuit 82. Then the pulse motor 4 is driven by one line's content while being separated into the four stages and each block of the thermal head is driven splittingly attended with each split movement to apply the print for one line. Thus, no discontinuity exists between the print blocks and the uniformity is kept.

Abstract: PURPOSE:To obtain good commutation performance with a small sized commutator by a method wherein the most suitable transformer voltage is constantly obtained by combining an auxiliary winding wound in wave form with a main winding, and equalizers are eliminated.

When the factors of respective winding are indicated as follows; number of parallel circuit = a1, a2, number of multiplication = m1, m2, number of turn = n1, n2, short-pitch winding factor = k1, k2, K1, K2, then it becomes as p = 2, a1 = 2, m1 = 3, n1 = 2, k1 = sin(8/9.pi/2) = 0.985 in the winding 31, and p = 2, a2 = 1, m2 = 2, n2 = 1, k2 = sin(4/9.pi/2) = 0.643 in the winding 32. Therefor by the relation of K = p/a.1/m.n.k, it becomes as K1 = 0.656, K2 = 0.643, and both values get similar. As the most suitable voltage value of transformer against the variation of magnetic flux of pole can be selected by this way, commutation is improved and equalizers are eliminated being able to miniaturize the commutator.
