Abstract: PURPOSE:To obtain an exposing method with which high degree of resolution can be obtained by increasing efficiency using the reticle formed by a light- shielding part and a light-transmitting part only and by providing an auxiliary pattern. CONSTITUTION:When a reticle 11, having auxiliary patterns 12b and 12c of the size smaller than the limit of resolution in the vicinity of a circuit pattern 12a, is going to be illuminated, the light flux L2 which illuminates the reticle is inclined in the prescribed direction at the angle in accordance with the degree of minuteness of the pattern by regulating the light flux passing through the plane of the optical system of illumination, which becomes the Fourier surface of the reticle, in the region having the center point at the position which is made eccentric from the optical axis of the optical system of illumination. An equiwave-surfaced light flux, which is inverted in respective phase, can be made to irradiate on a circuit pattern and an auxiliary pattern, the amplitude distribution of the light flux passing through both patterns are cancelled each other, and a pattern image of the intensity distribution having a sharp peak can be obtained.

Abstract: PURPOSE:To simplify structure and reduce the possibility of a breakdown by coupling a main-body side interlocking member and a shutter side interlocking member together through two U-shaped elastic coupling pieces which face each other at an interval of 180 deg.. CONSTITUTION:A shift interlocking ring 46 as the main-by side interlocking member and a tilt interlocking ring 49 as the shutter side interlocking member fixed rotatably to a lens barrel tilt part 12 are coupled together through the two coupling piecess 55 and 55 made of U-shaped elastic metallic plates (leaf spring).

IPC: H01F27/28
Filed: 1978-03-22
Abstract: PURPOSE: To prevent a coil conductor from falling and improve its mechanical strength by reducing the radially dimensional tolerance of the coils.  
     CONSTITUTION: The parallel conductor n is nearly divided into two. Coils are wound around the respective conductors at their opposed position so that the coils transfer from the upper section to the lower section and from the lower section to the upper section. In other words, when the number of parallel conductors is two, the coils start being wound around the conductors 1 and 2 and transfer from the 1W and 2W of the upper section A to the 1W' and 2W' of the lower section B, then finish being wound with the winding ends 1' and 2' opposed to the winding start ends 1 and 2. In this case, both the sections A and B are divided into the number of conductors 5 and that of 6 in the radial direction and the radial dimensions differ by one conductor. As compared with the radial dimensions by the conventional method, these are reduced to one half.

Abstract: PURPOSE:To contrive miniaturization and low cost of the subject device by utilizing motion of a rectilinear frame for mounting and dismounting a disk to and from a motor shaft for moving an electromagnet as an external magnetic field impressing means between a regular position and a refuge position. CONSTITUTION:The electromagnet 11 is moved from a 2nd place, i.e. the refuge position to a 1st place, i.e. the regular position by interlocking the frame 3 in its further continuously rectilinear motion after mounting the disk with interlocking mechanisms 12-14 and 19. Then, the electromagnet 11 is moved from the 1st place, i.e. the regular position to the 2nd place, i.e. the refuge position by interlocking the rectilinear motion prior to dismounting the disk by the frame 3. By this method, the need of a safety mechanism or an interlock mechanism to be provided between an electromagnet moving operation and a disk mounting/dismounting operation is eliminated, and hence miniaturization and low cost of the device are contrived, while its reliability is promoted as well.
