Title: Process for the treatment of an effluent stream in a process for the production of aromatic carboxylic acid
Inventor: JEFFERY IAN CHARLES
IPC: C02F1/44
Filed: 1998-03-16
Granted: 2003-06-01
Abstract: An acidic organics-containing waste water stream derived from for example plant for the production of an aromatic carboxylic acid such as terephthalic acid is treated to allow recovery of alkali and water for recycle to the production process. The treatment comprises adjusting the pH of the waste water stream using an alkaline medium, oxidising the organics content of the stream to convert the same to water, carbon dioxide and (bi)carbonate ions, and supplying the treated stream to a reverse osmosis membrane to produce a retentate containing (bi)carbonate ions and cations derived from the alkaline medium and a permeate which is substantially free of those components. The retentate is recycled for use in adjustment of the pH of the waste water stream and, if desired, water-consuming facilities which can tolerate less pure water. The permeate may also be recycled, with or without further treatment, for use in a water-consuming facilities within and/or associated with the production plant.

Granted: 1999-08-11
Abstract: A disc revolving apparatus that executes proper control in case of irregular input of reproduction signals in comparison with reference signals or oscillation signals for prevention of overturn, stop, reverse and on DVD-RAM discs, failures may also be avoided. In case of incapability of detecting signals in the pre-cavity detecting circuit 53, the pulse generator 58 would generate an error signal to control the revolution of the disc 50 and in case of normal detection in the pre-cavity detection circuit 53, with the synchronous signal being detected normally at a preset interval, the error signal would be produced by the oscillation signal for controlling the revolution of the disc 50. In case of detection of synchronous signals by the pre-cavity detection circuit 53 at a preset interval, the synchronous clock of the reproduction signal of PLL circuit 54 would generate error signals for the control of revolution of the disc 50.

Granted: 2000-12-01
Abstract: A current comparator comprises first (1) and second (2) inputs for receiving input currents to be compared. During a first phase (1a) of a clock period the input currents are sensed and stored on first (N1, S7) and second (N2, S8) current memory circuits. On a second phase (1b) of the clock period a switching arrangement (S1 to S4) inverts the input currents and applies them together with the currents stored in the first (N1, S7) and second (N2, S8) current memory circuits to a regenerative latch circuit (P1, P2, S9, S10). During a third phase (2a) of the clock period the comparator produces the comparison result at an output (3). During a fourth phase switches (S5, S6, S9, S10, S11) are operated to reset the comparator to its initial state.

Abstract: The audiovisual sensing, display and communication module of this invention comprises an image sensor applicable for both infra red and visible light, a dual-spectrum image display, and an audio processing module including earphone and microphone, in which the visible light image and the infra red image can be directly displayed on the LCD panel. The dual-spectrum image sensor combining the  infra red light and the visible light can be installed in front of a user, and the elevation angel of the sensor can be adjusted. The audio and video signals are transmitted and received through a wireless communication device so that all users participating the same task form a communication network closely sharing the communication of audio, video and information signals. The wireless communication device can separate the transmission and reception into two modules and have an independent power supply. The function circuit of the transmission module can control the image sensing and the display status. A hidden microphone can detect the surrounding sound. The receiving module has another remote control transmission module circuit. The infra red and visible light image sensor can be made as an independent module which, after dismounting or assembly, can be connected to a wireless communication device and a large LCD display panel to form a fixed or portable dual-spectrum image sensing system. The invented module also provides a lighting device to  compensate the poor surrounding light.

Title: Soft absorbent tissue products having delayed moisture penetration
Inventor: GOULET MIKE THOMAS
IPC: D21H27/30
Filed: 1999-01-15
Granted: 2004-06-01
Abstract: Amine-modified polysiloxanes are applied to the opposite outer surfaces of a tissue product, such as the two outer surfaces of a 3-ply facial tissue, providing improved softness to the surfaces and a degree of hydrophobicity to prevent wet through of liquids during use. However, the degree of hydrophobicity is controlled by the chemical structure of the amine-modified polysiloxane and/or by blending the amine-modified polysiloxane with a more hydrophilic modified polysiloxane such that liquid is still allowed to enter the tissue structure in a reasonably short time to be absorbed by the center ply, but the absorption in combination with the hydrophobicity of the other outer surface substantially delays the liquid from passing completely through the tissue product.

Title: A method of manufacturing the gate spacer of the semiconductor chip
Inventor: LAI YEONG-CHIH
IPC: H01L21/28
Filed: 1999-02-11
Granted: 2000-08-01
Abstract: It is the manufacturing method for the gate spacer of the semiconductor chip. This invention provides a method of manufacturing the gate spacer of the semiconductor chip. Such a gate protrudes from the surface of the chip, and its surface of the chip comprises at least a field oxide settled in the neighboring regions of the gate which is used for the electric isolation. The top region of this gate is higher than that of the field oxide. Such a method initially forms the first dielectric on the surface of the chip to cover the gate and the field oxide, wherein the thickness covered at the top of the gate in the first dielectric is larger than that of covered at the top of the field oxide in the same dielectric. Next step is to form a second dielectric on the surface of the chip covered the first one which planarizes the surface of the chip. Then, the following procedure is to proceed the first etch toward the surface of the chip which deprieves of the second dielectric into the predetermined depth and lowers the thickness of the first dielectric at the top of the gate simultaneously. Later, please proceed the second etch from the surface of the chip of the second dielectric in order to remove the surface of the chip from the second one completely. Finally, please proceed the anisotropical third etch process toward the first dielectric of the surface of the chip to remove the first dielectric at the top of the gate completely and to form the spacer on the side-wall of the gate.
