Inventor: KANAI TEIZABURO
IPC: G06F17/50
Filed: 1985-09-06
Abstract: PURPOSE:To improve the performance of diagram data base management of 2-layer structure by generating a virtual referenced record when no referenced record exists so as to apply the operation of a referenced side record thereby quickening the data processing in a main memory. CONSTITUTION:If a data referencing a not existing data appears, a data base management system 2 in a main memory generates a virtual referenced data, the virtual referenced data is used to form a pointer chain tying the referenced data. The form of the virtual data differs from that of a conventional data and consists of an ID field and a referenced pointer group. In order to distinguish the virtual data and the conventional data, the system separating the data area is adopted. In registering the data referencing other data, the system 2 searches the referenced data based on the reference field at first. When the referenced data exists, the registration designation reference data is inserted and it is added to a chain of the reference data. When no reference data exists, the virtual data is generated, registered and the reference data is registered.

Abstract: PURPOSE:To reduce the size of a device by using a coil made of a superconductive material for a magnetizing device which magnetizes a Faraday rotor as to an optical isolator equipped with said magnetizing device. CONSTITUTION:Magnetic flux B in the center of the coil which is produced by the coil 9 made of the superconductive material is expressed by an equation. The number of turns is 20, radius of the coil is 1.5mm, and length of the coil is 5mm (with a coil radius (a), length 2L, and magnetic permeability mu), and the coil is placed in air. When the Faraday rotator 7 is made of YIG, a current of >=42A is only supplied to the coil so as to produce magnetic flux larger than the saturation magnetic flux of the YIG. When the section of the coil is 0.5mmX0.15mm, the current density is 56,000A/cm<2>. Therefore, even when the external diameter of the coil is about 3mmphi, the YIG is magnetized sufficiently, so the optical isolator is reduced in size.
