Title: Magnetic bubble memory element
Inventor: UMEZAKI HIROSHI
IPC: G11C11/14
Filed: 1986-02-07
Abstract: PURPOSE:To prevent the breakdown of a protective film by forming the protective film by two layers of an SiO2 or Si3N4 film and a high polymer resin film, and to reduce a chip area by placing efficiently the second electric conductor pattern. CONSTITUTION:Patterns 3-3'' of Au/Mo are provided on a bubble garnet 1 and an SiO2 film 2, and a soft magnetic material pattern (omitted in the figure), and a polyimide resin film 4' are superposed through an SiO2 or Si3N4 film 4. Subsequently, a pattern 5 is formed by providing a connecting hole and executing an Al vapor deposition. As for a high polymer resin, its film stress is small, therefore, even if the film thickness is set to >=1mum, no crack is generated, and the influence onto a bubble transfer due to the film stress does not become a problem either. In this way, the protective film thickness is increased remarkably by using partially the high polymer resin and the dielectric strength can be improved, and even if an electric conductor 3 and an electric conductor 5 cross as a plane, the breakdown can be prevented, it is not always necessary to place the electric conductor pattern 5 on the inner and outer peripheries of the chip, and the chip area can be reduced.

Abstract: PURPOSE:To correct a proximity effect, and to improve the accuracy of the drawing of a minute pattern by changing the density of a reticulate mesh formed to a projection mask in response to the area of an electron beam transmitting region in the exposure method through a contraction projection system. CONSTITUTION:Beams emitted from an electron gun 1 are made parallel by a lens 2, beams transmitting the projection mask 3 are contracted by a lens 4, and a resist film 6 on a wafer 5 is exposed. The projection mask 3 is manufactured by opening electron ray transmitting regions 10, 11 to the pattern forming region of a Pt foil 8 held by a frame such as a Si frame. The Pt mesh (approximately 1mum wire width) is left in the opening regions for reinforcement, but the density of the mesh is changed in response to the areas of the openings, the smaller the areas become, the more intervals are widened, and the mesh is omitted as shown in a pattern 11 as occasion calls. Accordingly, the proximity effect, through which the quantities of charge exposed differ by the effect of reflected electrons, can be corrected, and each pattern can be drawn with high accuracy.

Abstract: PURPOSE:To improve an error rate characteristic by analog/digital-converting two demodulation outputs obtained by means of orthogonal phase detection, reproducing a main data signal and an auxiliary data signal by means of a digital operation and correcting the errors of the auxiliary data signal and the main data signal. CONSTITUTION:Demodulation data Dp1 and Dq1 are inputted to a transversal equalizer 12 and intercode interference included in Dp1 and Dq1 is compensated.

Similarly, provided a  thickness of a body 2a is H2 and a density of a sealing liquid 53 is gamma, a force of gammaH2Ae  is exerted in a left direction. Provided a weight of a moving part such as a center  plate 9 secured to the measuring diaphragm 1 is W, a force in a right direction is  exerted by the weight. If the force in a right direction is a positive force, it produces a  force of W-gammaAe(H1+H2) on the whole. In this constitution, the weight W of the center  plate is equalized with gammaAe(H1+H2) through installation of connecting pipes 23a and  24a and the center plate 9.

Visible data is recorded on the surface of a tint block layer (c) 3 and the recording receiving layer (b) 2. The ink recording the visible data is strongly bonded to the recording receiving layer (b) 2 to prevent missing of the record due to release.
