摘要： A planar thin film magnetic head is disclosed wherein an axis of easy magnetization in the vicinity of a magnetic gap of a magnetic yoke is forcibly made coincident with the direction of a track width by a magnetic field due to current flowing in a conductor layer. Accordingly, even though the track width is small, a high magnetic permeability, low Barkhausen noise and linear responsiveness can be realized to thereby improve the sensitivity, output and linearity. In another aspect of the invention, a throat portion is eliminated from a thin film magnetic core forming a magnetic gap. The thin film magnetic core is configured such that a pair of magnetic members constituting the magnetic core are diverged from the magnetic gap so that a divergent angle .theta., of first opposite side edges of the magnetic members, from a direction of the gap length of the magnetic gap, is set to the range of 30.degree..ltoreq..theta..ltoreq.80.degree., and the magnetic members have second opposite side edges extending in substantially parallel to the direction of the gap length of the magnetic gap. Accordingly, even though a track width is reduced less than 10 .mu.m, adjoining crosstalk or off track crosstalk can be avoided to thereby realize low-noise and high quality reproduction and improve the operating characteristics.

摘要： A method or system for bringing a movable element of a stepper motor to its home position by mechanically blocking the movable element from further moving from the home position, wherein the movable element is moved in one direction by repeating an energization cycle in which windings for sequentially establishing different energization phases are energized in a predetermined sequence at a predetermined interval from one phase to another. After the movable element is mechanically blocked, a motor driver circuit energizes at least one of the windings which corresponds to at least one of the energization phases that precedes another of the energization phases which corresponds to the home position of the movable element. This energization of the winding or windings for each preceding phase continues for a time longer than the predetermined energization interval of the normal energization cycle. Then, the phase corresponding to the home position of the movable element is maintained to hold the motor stopped at the predetermined home position.

摘要： In a video tape recorder, recording and reproducing heads record and reproduce a recording signal on recording tracks which are diagonally formed one after another on a tape-like recording medium. The recording heads are capable of recording again the same recording signal in the same recording region. If a recording error occurs during recording mode, information on where the recording error has occurred and a recording signal to be recorded are stored in a memory. During rerecording mode, the stored information is used to complement the recording error. If a recording error occurs, preliminary recording circuitry operates so as to complement this recording error. The above construction permits the recording signal to be recorded on the recording tracks with certainty.

摘要： A printer including a stepper motor for moving a carriage, a detector for detecting arrival of the carriage at a detection point within a range of the carriage movement, a stop for determining one end of the carriage movement range, and a first setting device operable upon power application to the printer, for activating the motor to move the carriage toward the stop until the carriage arrives at the detection point, and further activating the carriage in the same direction by a predetermined number of steps from the detection point such that the motor is activated without displacement thereof with the carriage held in abutment on the stop for at least the last one step, whereby a zero point of the carriage is established for the first time after the power application. The printer further includes a distance detecting device operable after the establishment of the carriage zero point, for detecting a distance between the stop and the detection point, and a second setting device operable when it is required to establish the carriage zero point for a second and subsequent times after the power application. The second setting device establishes the carriage zero point, based on the distance.

摘要： In an electronic control system having a main CPU and a slave CPU which is under the control of the main CPU, a power control circuit is provided between the power source and the slave CPU to stop supplying power to the slave CPU until the main CPU starts normal operation when the power to the overall system is turned on. The slave CPU does not start operation until the main CPU becomes capable of normal operation and control over the slave CPU, which prevents unexpected action of the slave CPU and the subordinate control object. The power control circuit is also effective in preventing the abnormal action of the slave CPU when the power to the overall system is turned off.

摘要： A typewriter having an automatic erasing function, having an erasing device responsive to an erasure-start key, for effecting an erasing operation to successively erase the characters printed by a printing device, and a controller responsive to the erasure-stop key, for permitting the erasing device to interrupt the erasing operation. The typewriter has an input buffer for storing input data which is entered through a keyboard while the erasing device is operated, the typewriter. The typewriter may be arranged so that the input buffer is cleared upon operation of an erasure-stop key. The above arrangement may be adapted to erase successive words on a display device as character and space data are retrieved from a memory. In this case, a device may be provided to suspend a continuous erasing operation for a predetermined time each time the space data representative of a space between the words has been retrieved from the memory after at least one character has been erased.
