Patent TW-441123-B (TW)
Title: A resonant-tunneling heterostructure bipolar transistor
Inventor: LIOU WEN-CHAU
IPC: H01L29/737
Filed: 2000-02-10
Granted: 2001-06-16
Abstract: In this invention, we fabricate a new functional resonant-tunneling heterostructure bipolar transistor. In this device, N-AlGaAs, n-GaAs, and n-InGaAs materials are employed as emitter layers. The base layer is grown by an ultrathin p<SP>+</SP>-GaAs layer. Under normal operation mode, the device can exhibit excellent trransistor performances including high current gain, low offset voltage, and N-shaped negative-differential-resistance (NDR) phenomenon simultaneously at room temperature. Due to the insertion of n-GaAs at emitter layer, the potential spike at emitter-base (E-B) junction could be decreased. Thus, the collector-emitter (C-E) offset voltage can be substantially efficiency reduced. In addition, a high current gain is achieved attributed to the use of ultrathin base layer and the reduction of neutral base recombination current. Significantly, the transistor performances incorporating an interesting N-shaped NDR phenomenon are observed under large forward E-B bias at room temperature. That is mainly due to the resonant tunneling of electrons from depleted GaAs emitter (triangular barriers) to collector through the InGaAs quantum well (QW) and ultrathin base layer. Consequently, these properties make the device have a good potential for amplifier, oscillation and logic circuit applications.

Granted: 2003-04-01
Abstract: A fibrous substrate, in particular a fibrous substrate comprising a microfine fiber-forming fiber is impregnated with a composite resin emulsion obtained by emulsion-polymerizing an ethylenically unsaturated monomer (B) in the presence of a polyurethane-based emulsion (A) at a weight ratio of the (A)/the (B) of 90/10 to 10/90, the emulsion having heat-sensible gelatinizing ability making it possible to supply a film having a specific elastic modulus. Subsequently, the emulsion is gelatinized. In the case that the fibrous substrate is a microfine fiber-forming fiber, this fiber is converted into a microfine fiber bundle. In this way, a leather-like sheet is produced. This process makes it possible to obtain a leather-like sheet having excellent softness and fulfillment feeling, and good hand touch, feel and physical properties like natural leather. In the case that the fibrous substrate particularly comprises a microfine fiber, it is possible to obtain a leather-like sheet having the above-mentioned characteristics and suede-like high-quality.

Title: Bi-directional pitch enhancement in speech coding systems
Inventor: GAO YANG
IPC: G10L21/02
Filed: 2000-07-01
Granted: 2002-01-21
Abstract: A bi-directional pitch enhancement system for speech coding systems. As speech data applications continue to operate in areas having intrinsic bandwidth limitations, the perceptual quality of reproduced speech data in typical speech coding systems suffers significantly. The present invention employs forward pitch enhancement and backward pitch enhancement to maintain a high perceptual quality in reproduced speech. In certain embodiments of the invention, the forward pitch enhancement and the backward pitch enhancement are performed in a single portion of the entire speech coding system. For example, in speech codec's, the forward and the backward pitch enhancement are performed only in the speech codec's encoder, or alternatively, only in the speech codec's decoder. If desired, the forward and the backward pitch enhancement are performed in a distributed manner, each being performed, at least in part, in each one of the encoder and the decoder of the speech codec. If desired, the backward pitch enhancement is generated using the forward pitch enhancement itself. The backward pitch enhancement is a mirror image of the forward pitch enhancement that is previously generated; the backward pitch enhancement is generated dependent on the forward pitch enhancement. Alternatively, in other embodiments of the invention, the backward pitch enhancement is generated independent of the forward pitch enhancement; the backward pitch enhancement is generated irrespective of the forward pitch enhancement that has previously been generated. The backward pitch enhancement is usually performed on the fixed codebook in code excited linear prediction (CELP) or is performed as post-processing in the decoder.

Title: Stabilization structure of suspension-type aeration plate
Inventor: LI SEN-YUNG
IPC: A01K61/00
Filed: 2000-07-05
Granted: 2002-09-21
Abstract: The present invention relates to a stabilization structure of a suspension-type aeration plate, which comprises a flotation body; three bent lever frames; a fastening ring; an aeration plate; and a positioning frame. The stabilization structure of suspension-type aeration plate having a simple structure and stability is designed by using the torque generated by the gravitational force, the rigidity of a structure, the buoyancy and resistance of a liquid, and the flexibility of a rope. The position and depth of the invented structure can be arbitrarily adjusted. Since it has a self-stabilized adjustment force, the structure can resist an external force and the waves on a liquid surface when it is placed in the liquid. When the structure is combined with an aeration plate, only an air pump is needed to supply the gas such that the structure is a structural design which is economical in power consumption. Furthermore, the bubble-discharging face of the aeration plate can always face upwards so that the stabilization structure of the suspension-type aeration plate can return to the original position and orientation.
