Patent JP-H0522124-A (JP)
Title: Pll circuit
Inventor: KATOU ICHIROU
IPC: H03L7/08
Filed: 1991-07-09
Abstract: PURPOSE:To prevent phase error from being generated by a data signal by removing the data signal and extracting a clock signal by gating an input signal. CONSTITUTION:When the input signal containing clock information and data information is inputted, a separating circuit 11 removes a pulse which rises after a 1/2 clock cycle is lapsed from the rise edge of a signal. Although it is not clear at an operation starting time point whether the pulse to be removed is data or clocks, in the clock, the pulse is existent for each cycle. Since the case of not having the existence of the pulse is generated corresponding to whether the value of the data is '0' or '1', the pulse to be removed is data without fail after the time point when this pulse is not existent. Thus, the clock signal can be separated from the input signal after the lapse of proper time. Since the output of the circuit 11 is the clock signal, no phase error is generated at the operation of the PLL composed of a following phase comparator 12, loop filter 13 and VCO 14.

Abstract: PURPOSE: To prevent recognition due to an omission of a fall of frequency analytic data of a consonant, etc., of an input speech from its resampled data by checking whether or not frequency analytic data of a specific frequency band in a specific speech part section of the input speech has a minimum value. CONSTITUTION: A frequency analysis of the input speech is taken, and the frequency analytic data in a speech section 2 is resampled 4 to generate an input speech pattern, which is matched against a previously generated dictionary patterns 6 to recognize the input speech. At this time, the frequency analytic data 3 in the specific frequency band in the specific partial section of the input speech is searched for according to the recognition result of the input speech when necessary.

Title: Data transmitting method using scrambler/descrambler
Inventor: YAMAMOTO KAZUHISA
IPC: H04L9/00
Filed: 1982-09-30
Abstract: PURPOSE:To secure privacy and to simplify hardware by changing a synchronous pattern in each set, and relating the synchronous pattern to a scrambler pattern at the ratio of 1 to 1. CONSTITUTION:A frame synchronizing signal pattern is sent by turning a switch 3. At the sending of the frame synchronizing signal pattern, the switch 3 is connected to the earth side, and at the sending of data, the switch 3 is connected to the input terminal 1 side, so that only the transmission data are scrambled and the prescribed frame synchronizing signal pattern is sent. The receiving side detects the prescirbed frame synchronizing signal pattern from the transmitted data and the data synchronized and scrambled on the basis of the detected pattern are restored to the original data through a descrambler. Therefore, a dif- ferent pattern is formed in each setting to secure privacy. On the viewpoint of hardware, only the scramble pattern may be controlled without using a frame pattern generating circuit independently to simplify the control.

Filed: 1983-09-14
Abstract: PURPOSE:To etch uniformly a sample to be etched at a high speed by impressing a magnetic field on the front side of a cathode on which the sample is placed and scanning plural magnets having prescribed inter-pole gaps in one direction so as to face the rear side of the cathode. CONSTITUTION:Reactive gas is introduced through an introducing port 13 into an etching chamber 13 and is maintained under prescribed pressure. High-frequency electric power is impressed to a cathode 12. Glow discharge arises between the cathode 12 and the bottom wall of the etching chamber and a low- density plasma region 31 is generated. Magnetron discharge is simultaneously generated in the respective inter-pole gaps by the effect of an electric field E and a magnetic field B intersecting orthogonally with each other, by which a high-density plasma region 32 is generated along the inter-pole gaps. Permanent magnets 19 are scanned in one direction of an endless track 20 by which the magnets are moved over the sample 18. The SiO2 film formed on the surface of the sample 18 is thus etched at a high speed and the time exposed to the region 32 is made approximately equal at the optional point on the sample 18. The distance between the magnets 19 and the rear side of the cathode 12 is maintained constant.
