Title: Plate-shaped thickness-shear crystal resonator
Inventor: SUGITA MITSUYUKI
IPC: H03K3/03
Filed: 1985-07-15
Abstract: PURPOSE:To obtain a three-times harmonic wave of a high stable oscillation without adding an LC turning circuit, by determining a dimension ratio of a diameter and a thickness of a vibrator so that its oscillation is executed stably. CONSTITUTION:A diameter and a thickness of a plate-shaped thickness vibrator are denoted as D and T, respectively. A relation of a difference of a negative resistance value of an oscillating circuit having no LC tuning circuit and an impedance of a crystal resonator, and a dimension ratio D/T becomes as shown in the figure. According to this graph, a three-times harmonic wave is vibrated between a point A and a point B, and 10<D/T<24 is derived. As a matter of fact, the oscillation is unstable in the vicinity of D/T=10 and D/T=24, therefore, when the D/T ratio is determined by avoiding its vicinity, the crystal resonator by the three-time harmonic wave is obtained.

Filed: 1989-06-20
Abstract: PURPOSE: To improve reliability by providing error correction ability in a storage sub system provided with a cache. CONSTITUTION: Setting is performed so as to be the same size as a data cache 18 in a storage controller provided with a dedicated storage buffer function. A first data transfer means takes out data corresponding to a data transfer instruction from an extension storage device to a storage buffer and loads the taken-out data to the dedicated storage buffer. A second data transfer means takes out the data from the dedicated storage butter and loads the data to a real storage device when the data transfer instruction from the storage buffer to the real storage device is generated. In the meantime, during data transfer to an L2 cache, an address/key monitors the uncorrectable error row of an L3 memory. Then, when the generation of an error is detected, required measures are adopted.

Filed: 1995-05-31
Abstract: PURPOSE: To easily and inexpensively obtain a sharp band pass filter characteristic. CONSTITUTION: Adjacent microstrip lines S1 and S2 are shown by inductors L1 and L2 and a mutual guide coefficient M. A first parallel resonance circuit is constituted by a capacitor C1 and the inductor L1 on an input terminal T1- side, and a second parallel resonance circuit is constituted by the inductor L2 and a capacitor C2 on an output terminal T2-side.

Title: Infinite impulse response filter and method of forming signal
Inventor: ROBAATO RUISU KUUBO
IPC: H03H21/00
Filed: 1989-06-21
Abstract: PURPOSE: To attenuate a phase jitter by increasing the radius of a complex conjugate pole from a prescribed start value of less than unity to a 2nd prescribed value less than unity after modifying the angle change of the complex conjugate pole until a filter converges on the phase of jitter and increasing the gain of the filter. CONSTITUTION: A phase predictive calculator 55 calculates a phase predictive value 4 of a jitter component that is included in a symbol and transmits the predictive value to an ALEIIR filter 70. The ALE 70 adjusts the angle displacement of a complex conjugate pole in the direction of the phase angle ω0 of jitter based on the value 4 and the previous value of θ2 . The angle displacement of the complex conjugate pole converges to the phase angle ω0 within reception of N predictive values from the calculator 55. When the angle displacement converges on the phase angle ω0 of the jitter, the value of θ2 which is outputted to a lead 71 is extremely close to the value of a phase angle of the jitter. Accordingly, the ALE 70 increases the radius of the complex conjugate pole within a unit circle.

Abstract: PURPOSE:To prevent a generation of a dark current and a flake by a method wherein a value of impurity concentration from at least one diffused layer of respective diffused layers to a semiconductor layer forming its diffused layer is minimized in a PN junction. CONSTITUTION:A P-type well layer 22 composed of a P-type semiconductor layer having low concentration is formed on a surface of an N-type semiconductor substrate 21.
