Title: Method of recovering p-hydroxybenzoic acid from the waste water from the process of producing p-hydroxybenzoic acid
Inventor: CHEN NI-HUEI
IPC: C07C51/42
Filed: 1998-09-28
Granted: 2005-04-01
Abstract: The present invention relates to a method of recovering p-hydroxybenzoic acid from the waste water from the process of producing p-hydroxybenzoic acid, comprising extraction of p-hydroxybenzoic acid from the waste water from the process of producing p-hydroxybenzoic acid by using organic solvents, and then extraction of p-hydroxybenzoic acid solved in the organic solvents by using basic solvents, followed by acidification and solid-liquid separation thereof, so as to obtain the crude crystal of p-hydroxybenzoic acid. The crude crystal of p-hydroxybenzoic acid can further produce p-hydroxybenzoic acid having higher purity through a re-crystallization step, or carry the esterification or etherification reaction out directly without purification, so as to obtain highly pure ester or ether compounds of p-hydroxybenzoic acid. According to the method of the present invention, the organic solvents for extraction, which can be reused repeatedly, not only recover the useful product, p-hydroxybenzoic acid, but also reduce the chemical oxygen demand (COD) in the waste water from the process of producing p-hydroxybenzoic acid by a half thereof or more; thus the expenses for treating the waste water are greatly reduced, and the purpose of industrial waste abatement is also achieved.

Granted: 2000-12-21
Abstract: A write driver apparatus (10) is adapted for producing a first data output signal and a second data output signal used in driving data onto a bit line pair (16, 18) associated with an electronic computer memory. The first and second data output signals represent desired data and are produced in response to a data signal, refill signal, and a data propagation clock signal. The data propagation signal is derived from system clock signals. A precharge circuit (12) associated with the write driver (10) operates in response to a precharge clock signal to precharge the bit lines (16, 18) prior to each read or write operation. The precharge clock signal is related to the data propagation signal to ensure that the bit lines (16, 18) are fully precharged prior to a read operation. A keeper circuit (14) associated with the bit lines (16, 18) also helps maintain a desired charge state on the bit lines during a read operation from memory cells (20) connected to the bit lines.

Title: Hand-held refractor for pediatric refraction - reading the refraction from the distance between light path and viewing line rather than from the crescent size
Inventor: WANG AI-HOU
IPC: A61B3/028
Filed: 1999-05-03
Granted: 2000-12-11
Abstract: Refracting young children is important for amblyopia prevention. It's difficult and remains a major challenge to pediatric ophthalmologist. Autorefractor is applicable only for children older than 2 year. Photorefraction is suitable for pediatric refraction because it refracts at a distance away from the children. Conventional photorefractor employs fixed distance (d) between light path and viewing line and reads refraction (r) from crescent size (s). At high refractive error the crescent size reaches plateau and refraction is thus read in bad resolution. A hand-held refrator was designed for pediatric use, which was constructed by minor modification from direct ophthalmoscope. By changing d to reach a fixed crescent/pupil ratio (s) and we read refraction (r) from d. r has a linear relationship with d. Along 5cm range of d, refraction from -14D to +10D could be easily read with good resolution. And from its handiness, axis and power of astigmatism could also be easily determined.
