IPC: H04Q11/04
Filed: 1990-11-14
Abstract: PURPOSE: To improve the flexibility of assigning a slot by separately providing an integrated link controller on transmitting and receiving sides and dynamically assigning the bandwidth of an information signal. CONSTITUTION: When a voice channel requests for slot use in a T-carrier interface of an integrated link controller 12 on a receiving side, a circuit monitor 70 detects it and sends a request control signal on a line 75 to an integrated link processor 60.

Filed: 1986-12-26
Abstract: PURPOSE:To improve the jitter durability remarkably by applying digital signal processing so as to attain circuit integration thereby attain remarkable reduction of scale of mount, low power consumption and low cost. CONSTITUTION:After an equalizing signal inputted to an input terminal 1 is sampled by a sampling circuit 7 and converted into a binary coding signal by an A/D converter 8.

A subtractor circuit 16 outputs a binary code signal being a difference when the code speed of the input equalizing waveform is changed and a ROM 17 outputs a multiplication coefficient signal changing the phase of a digital tank circuit 18 so as to cancel the phase of the difference corresponding to the difference code.

Title: Method and apparatus for changing optical beam state
Inventor: MIYAWAKI MAMORU
IPC: G02B5/18
Filed: 1986-12-27
Abstract: PURPOSE:To expand a focal distance varying range and to execute stable operation by radiating electron beams to the surface of an electro-optical crystal to form a charge pattern and changing a refractive index on the basis of the charge pattern. CONSTITUTION:Electron beams from an electron beam generator 1 are radiated to the electro-optical crystal 3 through a secondary electron collecting electrode 2. Since the generator 1 rotates around a rotating shaft 10, charge for a diffraction grating type lens pattern 50 is accumulated on the whole surface of the crystal 30. An electric field corresponding to the pattern 50 is formed on the crystal 30 by the accumulation of charge. A difference in the diffractive index is generated on the crystal 3 by the electric field in accordance with the pattern 50. Thereby, the focal distance can be changed by making incident laser beams 14 incident upon the crystal 3. Thus, the focal distance varying range can be expanded and stable operation can be attained.
