Title: Deflection coil for scanning electron microscope
Inventor: YUKITA NORIFUMI
IPC: H01J37/147
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To save the cost by providing a coil between an objective lens and a convergent lens, and changing the winding method of a deflection coil to simplify its form. SOLUTION: The electron beams from an electron gun is finely converged by a convergent lens and an objective lens, and scanned on a sample by a deflection coil. A coil 14a wound in a square loop is formed so as to be closely attached to the circumference of a cylindrical bobbin 13a with a saddle-shaped coil form, and a wire is collectively wound thereon. Such coils are mounted so as to be mutually opposed in 90 deg.-direction and vertically integrated, whereby the coil is used for the deflection of electron beams. According to this method, the form of the coil can be simplified. In order to close the magnetic field generated from the coil, a ferrite core 15 is arranged on the outside in the same manner as distributed winding method.

Title: Card type gate device
IPC: G07B11/02
Filed: 1992-03-31
Abstract: PURPOSE:To speed up the card reception processing of a gate device for which a card is used instead of an entrance ticket. CONSTITUTION:Standard time till the reading of a magnetic stripe 3 is started from the reception of the card 1 is set. When the reading cannot be started even if time is up, it is judged whether the inserting direction of the card 1 is mistaken or a card 1 itself is illegal to omit the retry of reading. Then, the card 1 is immediately sent out to e defective card returning port. Thus, meaningless retry when the reading of card information is evidently impossible is eliminated and the reception processing is speeded up.

Abstract: PURPOSE:To prevent the adhesion of the peeled substance of an inner film of a vacuum chamber to an optical substrate and to suppress the generation of pin holes by covering the inner wall of the vacuum chamber in a thin film forming room and an adhesion preventing plate with a net-like linear material. CONSTITUTION:A substrate 1 is led into the film forming room, a thin film 11 with a high refractive index, a recording film 12 and a protection film 13 are successively formed and these formed films are taken out from a substrate taking-out room. At the time of sputter adhesion to be used for forming the films 11-13, sputter grains are stuck to the substrate 1, the adhesion preventing plate 4 and stainless steel wire gauze 5. Although the sputter grains stuck to the plate 4 are peeled off when deposited substances are integrated and the inner stress of the film is increased, the peeled substances are not reached to the substrate 1 because they are catched by the wire gauge 5. Consequently, a film forming process prevented from the generation of pin holes can be obtained and the magneto-optical recording medium with a low defect rate can be formed.

Title: Manufacture of two-level crossing electrode
Inventor: ITOU MASAKI
IPC: H01L21/306
Filed: 1981-07-08
Abstract: PURPOSE:To obtain a two-level crossing electrode with higher integration and lower capacitance by forming an electrode pattern on a region which includes a region over a patterned organic matter obtained by the oxygen-ion etching of a lower organic matter layer through the use of a patterned resist as a mask. CONSTITUTION:A polyimide resin layer 5 is used to adherently cover Al electrodes 2-4 on a substrate 1, and accelerated oxygen ions are radiated to the entire surface with a resist mask 6 applied. This causes a patterned resin film 7 to be obtained. The entire surface is then adherently covered by a conducting film 8, and etched with a resist mask 9 applied, to form a conducting pattern 10. Then the resist and the polyimide resin are removed by an O2 plasma to form a space 11 at the two-level crossing portion. The etched speed of an organic matter film is far greater than that of an inorganic matter when subjected to the accelerated O ion radiation. Thus, a two-level crossing electrode having higher integration and lower electric capacitance can be obtained.
