    摘要: A memory access control apparatus according to the present invention which controls an IC memory of which is under the control of a BIOS in the same manner as in a normal disk unit. External file units including the IC memory, a floppy disk unit, a hard disk unit, and the like are assigned a series of drive numbers. Registers store parameters for using the IC memory as an external file, and an access address and a transfer length of the IC memory are expressed in a sector form. The BIOS receives the access address and the parameters, translates the address into a byte form address, and transfers data to a corresponding area.

    摘要: A dielectric ceramic material composed of primary and secondary ingredients forming in combination a polycrystalline ceramic proper, and of insulating substances diffused throughout the intergranular boundaries of the ceramic proper for an increase in apparent relative dielectric constant. The primary ingredients comprise, in relative proportions, 90.68-99.88 wt. % SrTiO.sub.3, 0.07-5.32 wt. % Nb.sub.2 O.sub.5, and 0.05-4.00 wt. % GeO.sub.2. The secondary ingredients comprise 0.02-0.10 wt. part SiO.sub.2 and 0.01-0.03 wt. part Al.sub.2 O.sub.3 with respect to 100 wt. parts of the primary ingredients, with the weight ratio of SiO.sub.2 to Al.sub.2 O.sub.3 being from 1.5 to 5.0. The insulating substances comprise 0.03-2.90 wt. % PbO, 0.11-4.34 wt. % Bi.sub.2 O.sub.3, and 0.001-0.18 wt. % B.sub.2 O.sub.3 with respect to the total weight of the primary and the secondary ingredients. In the fabrication of bodies of the ceramic the mixture of the insulating substances is coated or otherwise layered on polycrystalline ceramic bodies prepared from the primary and secondary ingredients. The coated ceramic bodies are then heated to cause diffusion of the insulating substances throughout their intergranular boundaries.

    摘要: A probe for surface-resistivity measurement is provided in a surface-resistivity measuring apparatus for measuring a surface resistivity of a target. The probe includes an electrode and a contact portion. The contact portion has a specific resistance larger than the electrode. The contact portion is disposed on the electrode. The contact portion is capable of surface-contact with the target.
