Title: Method and apparatus for positioning employing step motor
Inventor: AOSHIMA NOBUYUKI
IPC: H02P8/08
Filed: 1993-06-17
Abstract: PURPOSE:To prevent the stop position from shifting due to step-out by conducting the positioning based on a set number of positioning steps. CONSTITUTION:A setting means 18 sets a plurality of different third numbers of steps by adding second numbers of steps, obtained by subtracting 1 and 2 from the number of patterns of exciting phase, to a first number of steps while being designated by a designating means 12. After a detecting means 10 detects a movable part 80, the step motor is reciprocated in the direction of a stopper 84 and when the fourth number of steps, i.e., the number of steps in the return path, matches the third number of steps, the third number of steps is set as the number of positioning steps and stored in a memory means 20. When the positioning is conducted after releasing the designating means 12, the movable part 80 is shifted by the number of positioning steps being stored after it is detected by the detecting means 10 and then stopped by a stopper 84 to be positioned. This constitution prevents the stopping position of the movable part 80 from being shifted from the stopper 84.

Title: Control circuit for selection signal digit number
Inventor: KUDOU ISAMU
IPC: H04Q3/555
Filed: 1978-11-27
Abstract: PURPOSE:To secure confirmation for matching of the selection signal digit number to the BWS (backward signal) of subsequent N-1, N-2 and N-3 by setting the memory relay of the digit received the erasion designation in correspondence to the steering relay in case the FWS (forward signal) is transmitted. CONSTITUTION:The transmission is started from the FWS of code C. In this case, relay DC operates at the point where diode D13 passed through, and relay DC is held. As a result, the fact that the transmitted 1st digit is code C is memorized. And in case the BWS of N-3 is received from IR under transmission of the FWS of next code D after transmission of code C, relay N3 operates at OS to be held. On the other hand, relay DS operates at OS when the FWS of code D is transmitted. Now with operation of relay N3, the operation of relay DS is continued. In case OS receives the BWS of N-3 under transmission of the FWS of code D, the transmission is impossible for the FWS of code A to confirm the fact that the control signal is erroneous for the BWS received from the remote IR.

Abstract: PURPOSE:To reduce the cost of the manufacture of an element, and to improve mass productivity thereof by forming a transistor element section, using a gallium arsenide epitaxial growth layer having excellent crystallizability and insulated from a single crystal silicon substrate as an active layer on the substrate. CONSTITUTION:An silicon single crystal substrate 10 is annealed at 1000 deg.C in a hydrogen atmosphere in order to remove an oxide film first. A growth temperature is held at 900 deg.C, GaP is grown in an epitaxial manner and a first intermediate layer 31 is shaped, and the growth temperature is held at 700 deg.C and a second intermediate layer 32 and a third intermediate layer 33 as superlattices are grown in the epitaxial manner. Vanadium is doped in order to bring an intermediate layer 30 to semi-insulating properties. The growth temperature is held at 700 deg.C, and the active layer 50 of an n-type GaAs epitaxial layer and a cap layer 51 are grown continuously. Accordingly, since the active layer 50 is insulated automatically from the substrate, a process in which an insulating layer is formed is unnecessitated, thus simplifying manufacture.

Title: Transformer winding
Inventor: ITAKURA OSAMU
IPC: H01F27/28
Filed: 1983-08-11
Abstract: PURPOSE:To equalize a current shunted to each conductor and to reduce loss in order to miniaturize a transformer, by changing radial positions of eight conductors passed between adjacent winding sections, the conductors being divided into four groups two of which consist of adjacent three conductors respectively while the other two of which consist of one conductor respectively. CONSTITUTION:In a passing section R, conductors are passed at four points on the bore side of a winding section 7. At the two points thereof, the adjacent three conductors (d, d, c) and (b, b, a) are passed across together, while at the other two points, the conductors (c) and (a) are passed alone respectively. Thus, the four groups of conductors change their radial position with each other, but the conductor belonging to the same group do not change their radial position. Therefore, the conductor positioned at the center of the four juxtaposed conductors comes to the end thereof, and the one positioned at the end comes to the center. In such a manner, the conductors are passed in a half of the winding sections S1-S14 so that the position occupied by each juxtaposed conductor is equalized over the whole winding length, and the current can be shunted correctly.

Title: Emitter follower circuit
Inventor: MATSUMOTO KOJI
IPC: H03K19/086
Filed: 1990-06-04
Abstract: PURPOSE:To prevent a delay time when an output signal changes from being increased by connecting a capacitor between a connecting point among an emitter of a 3rd transistor(TR) being a component of a 2nd emitter follower, a 1st resistor and a base of a 2nd TR. CONSTITUTION:When a signal higher than a reference level is inputted to an input terminal, a high level is outputted to a noninverting output terminal OUT and a low level is outputted to an inverting output terminal, inverse of OUT. Conversely, when a signal lower than the reference level is inputted, the relation of levels is reverse to above. A capacitor C31 is charged by an emitter follower TR Q33 in the transient state where the noninverting output signal is changed from a low to a high level. Thus, the circuit operation is higher than the case with charging through a time constant composed of a collector load resistor of a current switching type logic circuit and the delay time is less. Since a capacitor C21 is charged by a TR Q23 independent of the TR Q31 in the transient state where the noninverting output signal is changed from a high to a low level, the delay time is not increased.

IPC: G11B5/56
Filed: 1982-08-23
Abstract: PURPOSE:To improve easily and assuredly the accuracy of an azimuth angle, by exercising control to obtain the maximum output of reproduction by turning a magnetic head to a track in response to the reproduction output of the signal recorded to a recording medium. CONSTITUTION:A head assembly 2 including a head chip part 1 is supported rotatably toward an arrow (a) to the housing base part. Then the part 2 is turned slightly by applying the voltage to a piezoelectric element 4 which is fixed at one of its sides. The angle of this rotation responses directly to an azimuth angle and can be controlled with the voltage applied to the element 4. Therefore an optimum azimuth angle is obtained by reproducing a sink part which is previously recorded with equidistant bit lengths and then stopping the rotation of the assembly 2 at a time point when the reproduced signal has the maximum amplitude. Thus it is possible to improve easily and assuredly the accuracy of an azimuth angle.
