IPC: H04L27/20
Filed: 1994-09-20
Abstract: PURPOSE: To reduce the circuit scale by eliminating the need for two multipliers for I, Q,phases requiring a large circuit scale having been needed for a conventional circuit so as to suppress the increase in the capacity of a waveform generating memory. CONSTITUTION: I phase data stored tentatively in a shift register 301 are given to a waveform generating memory 303 as an address, from which a band limit waveform stored in advance and corresponding to the address is outputted to a polarity inverter 304, in which the polarity of the waveform is alternately inverted based on an I phase rectangular carrier clock. Its output is given to an adder 305 and an I phase output waveform (i) is obtained by adding 1 to the LSB synchronously with the rectangular carrier clock. On the other hand, the similar processing is applied to Q phase data stored tentatively in a shift register 306 by using the Q phase rectangular carrier clock whose phase differs by 90 deg. to obtain a Q phase output waveform (q). The both are added by an adder 311, from which desired output is obtained.

Title: Centrifugal separator having function of modifying sludge
Inventor: SUGAWARA YOSHIYUKI
IPC: C02F11/12
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To improve solid-liquid separation performance by a centrifugal separator without scarcely changing operation conditions and equipment by the constitution in which part of separated liquid discharged from a centrifugal separator for solid-liquid separation is returned to a sludge supply process for the separator. SOLUTION: By returning part of separated liquid from a centrifugal separator 1 to a sludge supply process 2, raw sludge to be supplied from the process 2 to the separator 1 is diluted. Therefore, although TS (total evaporation residue) of the raw sludge is somewhat reduced, VTS (organic substance content) is decreased sufficiently, and the difference in specific gravity between raw sludge water and sludge components increased to improve solid-liquid separation performance. When a separated liquid of low VTS is mixed with raw sludge, in the composition of sludge components in the raw sludge, the percentage of organic components of lower specific gravity decreases, while the percentage of inorganic components of higher specific gravity increases so that the specific gravity of the raw sludge increases to improve the solid-liquid separation performance of the centrifugal separator 1 using the difference in specific gravity.
