Abstract: PROBLEM TO BE SOLVED: To provide a clock-tree structure using dummy buffers and dummy latches, the informing load resistances and load capacities from the clock generating circuit to the final-stage latches and realizing high-speed processing and operation in an integrated circuit. SOLUTION: In this tree structure, logic cells having small areas and the same load resistances and load capacitances as those of buffers 12, 13 and 14 and latches 15 are formed on a space on a substrate on which other elements are not formed, and used as dummy latches and dummy buffers. The dummy buffers and dummy latches are incorporated so as to make the load resistances and load capacities which differ among the paths to the final-stage latches 15 the same. Which informing the load resistances and load capacitances to all the final-stage latches, a hierarchical connection is realized. As a result, the difference between minimum delay time and maximum delay time is removed, and an increase in clock skew is prevented.

IPC: H01F1/11
Filed: 1982-05-12
Abstract: PURPOSE:To obtain ferromagnetic iron oxide for magnetic recording with high transfer characteristics and high saturation magnetizability by heat treating gamma-Fe2O3 at a temp. above the oxidation temp. of a conventional method and below a temp. close to the temp. of transition from gamma-Fe2O3 to alpha-Fe2O3. CONSTITUTION:Ferromagnetic fine gamma-Fe2O3 powder is heat treated at a temp. from the critical temp. -200 deg.C to the critical temp. +30 deg.C to manufacture ferromagnetic iron oxide. The critical temp. of ferromagnetic gamma-Fe2O3 is defined as a heat treatment temp. at which partial transition from the gamma-Fe2O3 to alphaFe2O3is caused and the saturation magnetizability is reduced to 99% of the original value before heat treatment. When the heat treatment temp. is above the critical temp. +30 deg.C, remarkable transition from the alpha-Fe2O3 to gamma-Fe2O3 is caused, so the magnetism is deteriorated and it becomes difficult to use the resulting iron oxide as a magnetic body. When the temp. is blow the critical temp. -200 deg.C, little effect is produced.

Filed: 1988-03-31
Abstract: PURPOSE:To eliminate the spot like artifact appearing at the center of a reconstituted image by accurately detecting the real DC component of an MR signal, by taking out the data in the vicinity of frequency of zero by applying unidimensional Fourier transform to the raw data of one line to calculate the average value thereof. CONSTITUTION:The raw data obtained at every one line is sent to a unidimensional Fourier transform circuit 1 and the data at every frequency obtained herein is sent to a data extraction circuit 2 to extract some data having frequency in the vicinity of frequency of zero. These data are sent to an averaging circuit 3 to calculate the average value thereof. When DC noise is contained in the raw data, said data becomes extremely large as the data of frequency of zero. Contrarily, since DC noise is not contained in the data having frequency in the vicinity of the frequency of zero, said data becomes extremely small. Hereupon, the average value of the data having frequency in the vicinity of the frequency of zero can be estimated as the DC component of the real signal. Then, a DC noise component is calculated and the raw data having no error wherein said noise component removed is sent to a two-dimensional Fourier, transform circuit 9 to obtain an excellent reconstituted image having no spot like artifact.
