Abstract: PURPOSE:To examine the form of a pattern efficiently at a high speed and a high accuracy, by comparing the gap area between a set irradiation position found from the rotation slippage amount of the beam irradiation position and the irradiation form, and the actual irradiation position, with a set tolarable defect area. CONSTITUTION:The rotation of an examining sample 13 together with a cassette 17 is regulated by making the X-Y axial direction of an X-Y stage 16 as the standard, by recognizing an alignment mark, the sample 13 is conveyed in a chamber 14 and loaded on the stage 16, and the alignment mark is moved to the irradiation point of the electron beans by the control of an X-Y stage control device 18, so as to discharge the electron beams. A pattern examination deciding device 34 receives the electron amount from an electron detector 20 when the electron beams are radiated to the alignment mark, detects the rotation slippage amount theta of the actual irradiation position to a set beam irradiation position, and finds the slippage amount of an examination pattern irradiation beam, and a pattern defection area depending on the rotating slippage theta. When the pattern defection area is larger than the set tolerable defect area, it is decided that the pattern has a defect.

Filed: 1983-05-07
Abstract: PURPOSE:To prevent a needless damage of a tape and the increase of power consumption by pressing a pressing member which presses the magnetic tape to a fixed head, only when pressing is required and minimizing the bad influence upon the tape itself and the bad influence upon running of the tape. CONSTITUTION:In case of variable speed reproducing such as still picture reproducing, slow motion reproducing, high-speed search reproducing, or the like, information indicating that variable speed reproducing is performed is obtained from an operating part, and an eccentric cam 25 is rotated by a motor 36 in accordance with this information.

IPC: H01F37/00
Filed: 1990-03-27
Abstract: PURPOSE:To improve noise block performance and signal transmitting performance by connecting a pair of windings on the same magnetic legs not mutually coming face to face in series and with gene rated magnetic fields to a closed magnetic path in the same polarity. CONSTITUTION:Magnetic flux PHIS3, PHIS6 of a group 15 by means of windings 3, 6 become the same polarity with a closed magnetic path flow 17 while reversed polarity to the magnetic flux PHIS4, PHIS5 of the group 16 by means of the windings 4, 5 thus to mutually cancel. Further, PHIS3, PHIS4 cancel each other and PHIS3, PHIS5 also cancel each other. PHIS5, PHIS6 cancel each other and PHIS4, PHIS6 cancel each other. While the groups 15, 16 as the whole mutually cancel their magnetic flux, the winding 3 to 6 also cancel the flux mutually and minutely so that, inspite of magnetic diversity of a U-type core, the balance of a cancel of the generated flux improves. To a common noise current IN, the magnetic flux PHIN3 to N6 generated by means of the windings 3 to 6 are in the same polarity with the closed magnetic path so that the sum of inductance by means of the groups 15, 16 as the whole inductance blocks the current IN to the input terminals A and B. Thus, a noise block performance is improved.
