Abstract: PURPOSE:To allow a small-sized, light-weight device to actuate a optical head effectively by controlling a current flowing in inductors provided in parallel with each other and in all directions so as to confront a projecting part and driving a lens in a focusing or tracking direction. CONSTITUTION:When a current is caused to flow in the inductor 38, magnetic fluxes phiA and phiB occur in a direction A1-A2 and a direction B1-B2, respectively. Due to the balance of these magnetic fluxes phiA and phiB a movable body 30 rotates in a direction T with a spindle 32 as a center. This action is set to the direction tracking an optical disk, and the current in the inductor 38 is controlled to execute a tracking servo. According to the current flowing in the inductance 38, magnetic fluxes phiC and phiD occur in a direction C1-C2 and a direction D1-D2, respectively. Due to the balance of these magnetic fluxes phiC and phiD the movable body 30 can be moved in a direction F. Thus the current flowing in the inductor 38 is controlled, whereby the lens 34 can be driven by the prescribed amount in the focusing direction F and the tracking direction T.

Abstract: PURPOSE:To improve the directivity of the elevation angle direction of a nontracking type antenna used for the antenna system for a moving body by generating a circular polarized beam which is nondirectional in an azimuth angle direction and directional in the elevation angle direction. CONSTITUTION:First antenna elements 1 are arrayed clockwise or counterclockwise based upon a 1st antenna element 1 at constant intervals beta and when the polarized wave direction of, for example, a 1st antenna element antenna 1 is set to a fixed value alpha, the-polarization directions of other 2nd-(n)th antenna element 2(n) are so set that they are excited in the direction of the sum alpha+beta of the fixed value alpha and fixed interval value beta. For the purpose, >=3 1st-(n)th antenna elements 1-(n) are arrayed in this position relation to form a conic beam which is nondirectional in the direction of the azimuth angle phi and directional in the direction of the elevation angle #. Consequently, the nontracking type antenna has the directivity of the direction of the elevation angle theta made coincident with the directivity of the direction of the elevation angle theta at all times.

Abstract: PURPOSE:To aim at improvement in riding quality without entailing any damage on the action of an engine brake, by installing a controlling device which operates a lockup device at time of acceleration at accelerator operation release after receiving each output of an accelerator operation release detecting device and an acceleration detecting device. CONSTITUTION:A control unit 30 has an acceleration detecting device 102 which receives output of a turbine sensor 225 and judges it to be acceleration when a variation in turbine speed is positive.

Filed: 1982-04-22
Abstract: PURPOSE:To dispense with welding and simplify manufacturing process of a core holder by anchoring a sliding plate by means of louvered pieces to the outer periphery of a cylindrical member formed by drawing a galvanmized iron sheet. CONSTITUTION:A core holder 16 is a cylindrical member formed by drawing a galvanized iron sheet and which has Z-shaped hook parts 5 and 6 formed by louvering. In case of anchoring a sliding plate 1 to the cylindrical member, first, one anchor piece 9 of the sliding plate 1 is located in the hook parts 5 and  another anchor piece 9 is located in the hook parts 6 which are not subjected to  bending work yet, and then bending work is made. Consequently, welding work  can be dispensed with in the process from the formation of a core holder 16 to  the fitting of the sliding plate 1. Therefore, it becomes unnecessary to carry out galvanizing for rust proofing which is otherwise required after welding, and it becomes possible to use from the outset a galvanized iron sheet to which rust prevention has been applied. Therefore, not only the manufacturing process can be simplified, but also the deformation of the core holder which thends to occur during spot welding can be eliminated.
