Title: Series/parallel-type a/d conversion device
Inventor: KINUGASA NORIHIDE
IPC: H03M1/14
Filed: 2001-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a series/parallel-type A/D conversion device which can perform operation faster than a conventional device and which can easily correct high-order bit data. SOLUTION: The upper limit voltage VH of a voltage range where low-order bit conversion is performed is amplified by a second differential amplifier AMP2 with a center value voltage VM in the voltage range as a reference and becomes the high level reference voltage SUBH of a low-order bit conversion. The lower limit voltage VL of the voltage range is amplified by a third differential amplifier AMP3 with the voltage VM as the reference and becomes the low level reference voltage SUBL of low-order bit conversion. The voltage VIN of an input analog signal is amplified by a first differential amplifier AMP1 with the voltage VM as the reference and low-order bit data is obtained by a position that the obtained SUBIN occupies between the voltage SUBH and the voltage SUBL.  Since the voltage SUBH and the voltage SUBL do not change by the voltage VIN of the input analog signal, settling time is made shorter than that in a conventional case.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing a high quality artificial zeolite. SOLUTION: The method for producing the artificial zeolite comprises charging a raw material (slurry) preliminary heated to the reaction temperature into a reactor, and holding the reaction temperature basically by keeping warm for a prescribed reaction time to obtain an artificial zeolite with equal quality as that prepared in the laboratory, which is contrary to the conventional concept of heating and reacting in a reactor. There are variations in the apparatus such as a reactor type, a decentralized reactor type, a tubular type and a straight-tube type. In the decentralized reactor type, reactors are each operated cyclically with respect to a pair of heat-exchangers disposed at the front of the reactors. By using the tubular type reactor, nearly zero reaction error operation can be carried out resulting in production of a high quality artificial zeolite.  The artificial zeolite re-utilizing water glass shows CEC (cation exchange capacity) equal to that of a synthetic zeolite.
