Filed: 1989-05-09
Abstract: PURPOSE:To improve the dielectric strength of an insulating film by performing isotropic and anisotropic etching when a silicon substrate is etched and forming large angular bevels at the upper edge of a trench. CONSTITUTION:When anisotropic etching is successively performed to the surface of a silicon substrate 1 while the degree of vacuum is lowered to a prescribed value after an oxide film 2 which acts as a mask is formed on the surface of the substrate 1 and isotropic etching is performed to the surface of the substrate 1 under a prescribed condition by reactive ion etching, a trench 3 with angular bevels at its upper edge is formed. Since the upper edge of the trench 3 is largely beveled in the course of the isotropic etching process, concentration of electric fields can be relieved. Therefore, the dielectric strength of an insulating film 5 can be improved.

Title: Individual collating device
Inventor: YAHAGI HIRONORI
IPC: G06T7/00
Filed: 1989-05-08
Abstract: PURPOSE:To improve the accuracy for an individual collation by executing quickly a correct feature extraction by constituting this device so that a registering/collating means contains at least data from a thinning-out means and a pseudo feature point eliminating means and executes the registration and collation of a fingerprint. CONSTITUTION:A registering/collating means 15 contains at least data from a thinning- out means 8 and a pseudo feature point eliminating means 11 and executes the registra tion and collation of a fingerprint. Subsequently, each screen in the sealing process of a fingerprint is collected, it is binarized/converted to a thin line, and also, each thin line-converted image is thinned out by a mask of (n) X (n). By thinning-out, a rough processing is performed to the thin line, and especially, a noise of 'sweat gland'/'hair' disappears, and an appearance tendency in the sealing process is checked, and when an end point which appears in the beginning of the sealing process and disappears in the latter half exists therein, its point is eliminated as 'crack' from a feature point. On the other hand, when a branch point exists in the latter half although it does not appear in the beginning of the sealing process, its point is eliminat ed as 'bridge' from the feature point. In such a way, a pseudo feature point is eliminat ed appropriately, and a correct feature extraction is executed quickly.

Filed: 1991-05-20
Abstract: PURPOSE:To save the time needed for the clip processing and therefore to shorten the total arithmetic processing time when the operating speed of an arithmetic logic unit ALU is increased by delaying the clip value generation process by one time slot. CONSTITUTION:In regard to an arithmetic processing circuit, an arithmetic circuit 1 is clipped to its maximum treatable value if the arithmetic result of the circuit 1 overflowed. Then the operation of the circuit 1 is carried out. Under such conditions, an overflow detector means 2 is added to the circuit 1 and detects a fact that the arithmetic result of the circuit 1 overflowed.

Title: Contact switching mechanism
Inventor: MAENISHI KOZO
IPC: H01H9/46
Filed: 1988-05-11
Abstract: PURPOSE:To prevent consumption of a contact by arc by forming a protruding part extending to the forward side connected with the forward end of a fixed contact member, and extending the inner end of a movable side terminal member over a contact fixing position to the forward side. CONSTITUTION:Because of existence of a protruding part 31A formed at the forward end of a fixed contact member 29A and an extended part 40A formed at the forward end of a movable side terminal member 35A, arc Q transits to both parts 31A, 40A to extend an arc column. The arc Q gets apart from the fixed and movable contact members 29A, 37A in an early stage to transit to the side of an arc suppressing plate 45A. Because a magnetic flux is produced by a permanent magnet 49A disposed close to the contact, a forward drive force F is produced around the contact corresponding to the Flemming's left hand rule, and the arc Q can be moved to the side of the arc suppressing plate 45A securely. Abnormal heating of contacts 30A, 39A and the movable contact member 29A by the arc Q is thus eliminated, thereby consumption of the contacts 30A, 39A can be prevented.
