    摘要: A flexible magnetic diskette used for magnetically storing various information which is recorded and read by a magnetic head. The diskette includes a flexible plastic disk sheet uniformly coated with magnetic material and having a mount hole at its center, and a holder for securing the disk sheet over the periphery of the mount hole. The holder is also made of a plastic material for holding the flexible disk sheet over the peripheral portion of the mount hole via a double-sided adhesive ring. A core member is made of a magnetic metal having a high abrasive resistance and rigidly attached to the holder over at least a part of a surface of the holder, with which a drive unit is engaged.

    摘要: In a vehicle key device, when a key is inserted into a lock, the former is magnetically coupled to the latter so that data are transmitted therebetween, and only when the data provided by the lock and key correspond with each other is the driving of the engine permitted. This device positively prevents the driving of a vehicle by an unauthorized person.

    摘要: This invention relates to a method of correcting astigmatism in scanning electron microscopes and similar equipment which insures accurate correction of astigmatism simply by matching an astigmatism-correcting image, appearing on part of a Braun tube screen, to a predetermined point (such as a mark) on the screen, instead of depending on skill and perception. The apparatus for correcting astigmatism in scanning electron microscopes and similar equipment according to this invention provides a simple structure to implement the above astigmatism correcting method, connecting the X direction astigmatism correcting system through a first switch to one of the horizontal and vertical scanning systems and the Y direction astigmatism correcting system through the second switch to the other thereof.
