Title: A method for treating copper-containing waste liquid produced from printed circuit board manufacturing and electroplating processes
Inventor: HUANG GUO-SHIUN
IPC: C02F1/46
Filed: 2001-02-02
Granted: 2003-10-21
Abstract: This invention provides a treatment method for copper-containing waste liquid produced in a PCB or electroplating process, particularly to control the pH value of the waste water in the range below 3. Sodium sulfide or sodium hydrosulfide is added as a reactant, and the quantity added in wastewater is controlled by oxidation-reduction potentiometer, setting between 200 mV and -300 mV, to monitor the generation of cupric sulfide which can be removed by filtering method, or coagulated by polymer. The use of polymer can be avoided and the amount of sludge can be reduced. The copper concentration in the sludge is increased for better recycling, thus the sulfide precipitation method becomes a reliable waste liquid treatment method.

Inventor: SAKAMOTO NORIAKI
IPC: H01L21/56
Filed: 2001-02-15
Granted: 2002-05-11
Abstract: The conventional circuit substrate utilizes the printed substrate, ceramic substrate and flexible sheet material as the supporting substrate, and is installed with circuit devices. However, this supporting substrate is unnecessary and redundant material, and the thickness of the supporting substrate results in a problem in that the circuit device is large. After a trench 54 is formed in a conductive foil 60, a circuit element is mounted by a flip chip method. Then, an insulating resin 50 is covered on the conductive foil 60 as a supporting substrate. After reversion, the conductive foil 60 is polished over the insulating resin 50 as a supporting substrate at this time to separate the conductive paths. Accordingly, a circuit device having the conductive paths 51 and the circuit elements 52 supported by the insulating resin 50 can be produced without employing the supporting substrate.

This means that they must have high sensitivity and therefore also respond to electrical and magnetic fields. Therefore, they have previously been packed in an enclosure, which has an additional internal metal enclosure in the inside in order to protect them from electromagnetic radiation. In this optical receiver, the surface is coated with polysilicon, whereby the top-lying cathode contact is recessed. Furthermore, a thick oxide layer is arranged between the substrate and the polysilicon coating. Such optical receiver, which cannot be influenced by electromagnetic radiation, are primarily required for remote controls.

Patent TW-I223527-B (TW)
Title: Baseband processors and methods and systems for decoding a received signal having a transmitter or channel induced coupling between bits
Inventor: BOTTOMLEY GREGORY
IPC: H03M13/27
Filed: 2001-05-22
Granted: 2004-11-01
Abstract: Received signals are decoded based on a coupling between bits of the received signals introduced by the channel over which the signal is transmitted or by the transmitter which transmitted the signals. For example, in a higher-order modulation scheme, such as 8-PSK, individual bits grouped in a given symbol are generally coupled rather than fully independent. Accordingly, decoding information on a first one of the bits processed through a forward error correction decoder may be used to adjust the soft information from a demodulator for one or more of the other bits contained in the same symbol for use in processing those bits through the forward error correction decoder. Particularly where interleaving is utilized, a first bit may be processed through the decoder before the soft information on another of the bits is needed, thereby allowing an intermediate decision soft value for the first bit to be used in generating the input value to the decoder for the subsequent bit. Alternatively, a multi-pass process may be utilized which may allow all of the bits to be decoded utilizing soft information from the first decoding pass to affect the input to the decoder during the second pass for coupled bits such as those transmitted in a common symbol.
