Title: High-speed bit synchronization device with many-end control structure
Inventor: JIYU BOMU SUN
IPC: H03M5/06
Filed: 1995-03-27
Abstract: PURPOSE: To prevent a PLL loop gain from being sensitively chanted by a data bit pattern by providing a phase comparison gain limiter and avoiding gain limit of a phase comparator within a range of a transition occurrence frequency from NRZ data. CONSTITUTION: When a frequency synchronizing signal detector 25 outputs a frequency synchronizing signal, a phase difference output controller 26 provides an output of outputs UP, DP of a 1st phase frequency comparison gain controller 22 to a low pass filter 27, and when the detector 25 outputs no frequency synchronizing signal, no signal is given to the filter 27. When the frequency is not synchronized, the filter 27 applies low pass filtering only to outputs UF, DF of 2nd phase and frequency comparison gain limiters 24 and provides an output of only a low frequency component voltage including a DC component to a VCO 28.  When the frequency is synchronized, the filter 27 applies low pass filtering to the outputs UP, DP of the gain limiter 22 and the outputs UF, DF of the limiters 24 respectively and the voltage of the low frequency component voltage including a DC component to the VCO 28. The VCO 28 uses an output voltage of the filter 27 to change the phase and the frequency of the output clock pulse.

Abstract: PURPOSE:To allow the free insertion and removal of an inserting material into and from a living body by providing a tubular body which is introduced into the desired section in a living body and has the flexibility to allow the insertion of the inserting material therein in the lower part of a communicating hole ad providing an elastic plug which can be repeatedly pierced by the inserting material in the front end part thereof. CONSTITUTION:A grape sugar sensor 14 is projected from the front end of a sensor probe 18 and the front end thereof is immersed through the elastic plug 11 provided at the front end of a guide tube 10 into blood 24 running in a blood vessel 13. The sensor 14 is pulled from the plug 11 by pulling the operating part of the probe 18 and is retreated into the probe 18 so as not to come into contact with the blood 24 in the case of stopping the measurement of the blood sugar value. Since the plug 11 consists of the elastic material, such as silicone rubber, which can be repeatedly pierced, the plug is tightly and hermetically closed after the sensor 14 is pulled. The back flow of the blood 24 through the plug 11 into the tube 10 is thus obviated. The infiltration of foreign matter into the living body is prevented if a cap body 12 is previously screwed into the communicating hole 6.
