Abstract: PURPOSE:To obtain a channel stopper wherein an inverted layer is hard to yield by self-alignment and to implement element separation with low defects, by embedding poly Si or SiO2 including impurities whose conductive type is the same as that of a substrate in the side surface of a groove provided in the Si substrate. CONSTITUTION:An SiO2 film 2 and a resist mask 4 are provided on an N type epitaxial layer 8. Reactive ion etching is performed, and a groove 5 reaching a substrate 1 is formed. The inside of the groove 5 is oxidized, SiO2 at the bottom is removed, and poly Si 12 including P type impurities is formed, with the SiO2 film 11 being made to remain. A resist 13 is applied and recessed part of the upper part of the groove 5 is buried. The poly Si 12 is etched and only the inside of the groove 5 is made to remain. Then the surface is coated by a CVD SiO2 film 14, and a metal wiring 10 is applied. The concentration of the impurities in the poli Si in the groove is made high. Therefore, an inverted layer is not yielded even though the metal wiring passes on the groove, and a channel stopper is formed by self-alignment. Since Si3N4 is not used, crystal defects are not induced in the substrate during oxidation.

Title: Sample rate converting circuit
Inventor: YAMADA MASAHIRO
IPC: H04N7/00
Filed: 1987-09-18
Abstract: PURPOSE:To reduce the waveform distortion of an output over a wide range of a signal band by using an interpolration filter(IPF) having flat characteristics at 0-f1/2 band and cutting characteristics at >= f1/2 band to increase the sample rate of input data m times and to execute linear interpolation. CONSTITUTION:Input data xn are preprocessed by an interpolation filter (IPF) 31 through an input terminal 26 to execute interpolation. Output data from the IPF 31 are inputted to a linear interpolator 28.

Title: Magneto-optical disk
Inventor: KONISHI KATSUYUKI
IPC: G11B23/00
Filed: 1991-09-13
Abstract: PURPOSE:To improve the stability of an adhesive surface and to maintain the reliablity of strength of adhesive of a hub by having a hub provided with notches for absorbing the thermal deformation by thermal expansion or thermal shrinkage to drastically decrease the internal stress acting on the adhesive surface of the hub and a mangeto-optical disk substrate. CONSTITUTION:Notches 4 absorb the thermal deformation by the thermal expansion or thermal shrinkage peculiar to the magneto-optical disk, therefore, plural pieces of slits are provided across an attraction part 1b from the adhesive part 1a and the hub flank 1c. The force toward the center of the hole in the central part acts radially on the disk substrate 2 when the magneto-optical disk is exposed to a high temp. due to ambient temp. rise or the like. The hub 1 expands thermally as well and the force tending to spread toward the outer side in the diametral direction of the hub 1 acts on the adhesive part 1a. The slits are provided as the notches 4 and the thermal deformation of the hub is absorbed by the slits. Since the direction of the deformation is dispersed, the internal stress acting on the adhesive surface between the adhesive part 1a and the substrate 2 decreases.
