Inventor: JOHNSON RALPH H
IPC: H01S5/183
Filed: 2002-12-26
Abstract: An asymmetric distributed Bragg reflector (DBR) suitable for use in vertical cavity surface emitting lasers. The asymmetric DBR is comprised of stacked material layers having different indexes of refraction that are joined using asymmetrical transition regions in which the transition steps within a transition region have different material compositions, different doping levels, and different layer thicknesses. Adjacent transition regions have different transition steps. Thinner transition regions are relatively highly doped and are located where the optical standing wave within the DBR has a low field strength. Thicker transition regions are relatively lightly doped and are located where the optical standing wave has a relatively high field strength. Beneficially, in the AlxGa(1-X)As material system the stacked material layers are alternating layers of AlAs and GaAs. Other material systems will use other alternating layers.

Title: Scroll compressor
Inventor: KOSHO KAZUHIRO
IPC: F04C29/02
Filed: 2003-02-27
Abstract: A lubrication path (50) to press-contact surfaces of a fixed and orbiting scrolls (21, 22) serves also as a high-level pressure introduction passageway when a difference between a high-level pressure and a low-level pressure is great. On the other hand, when the high-level pressure introduction passageway is blocked off in a state in which the high-low pressure difference is small, refrigerating machine oil is supplied to the press-contact surfaces through a low-level pressure space (S1) within the casing, for controlling the pressing force of the orbiting scroll (22) against the fixed scroll (21), and the construction for preventing a decrease in efficiency is simplified, thereby not only reducing the cost but also preventing the occurrence of a maloperation.

Title: A polyester multilayer film and a bag thereof
Inventor: KUROKI TAKAYUKI
IPC: C08G63/183
Filed: 2003-03-17
Abstract: Because the present aliphatic polyester films possess the same or higher mechanical, optical, and thermophysical properties as the general films, and also being biodegradable, their wild-ranging applications on wrapping field have been always anticipated; however, the lack of property of heat-sealing of aliphatic polyester films, especially the films of lactic acid series polymers, makes a second-process, for example, the manufacture of bags, difficult to proceed, and therefore comes the problem of practicability. The problem the present invention attempts to solve is to provide a better polyester film which comprises outstanding heat-sealing property and is suitable for a second-process, for example, the manufacture of bags. The polyester multilayer film comprises a layer (layer A) which contains 50~100 wt% of poly (hydroxycarboxylic acid) aliphatic polyester (polyester A), and a layer (layer B) which contains 50~100 wt% of diol-dicarboxylic acid polycondensation polyester (polyester B).

Title: Method and apparatus for making cigarette filters with a centrally located flavored element
Inventor: LANIER ROBERT C JR
IPC: A24D3/02
Filed: 2003-03-26
Abstract: A filter making apparatus includes a positioning device having a passageway therethrough, with the passageway guiding a continuous flavor element such as a continuous strand of textile material from an inlet of the passageway to an outlet of the passageway. A liquid flavorant is introduced into the passageway at a desired flow rate and the strand of material carries the supplied liquid flavorant out of the positioning device at a rate substantially equal to the desired flow rate. A portion of the passageway can form a bath of the liquid flavorant supplied to the passageway through a separate inlet at approximately atmospheric pressure. A portion of the positioning device guides the continuous strand of material through the bath, or guides the strand to pass along the bottom of the passageway, and the saturated or partially saturated strand of material then exits from an outlet of the passageway to a point in the path of filter tow material that is being converged to form a filter rod.

IPC: G10L11/02
Filed: 2003-03-27
Abstract: Communication systems are described, including both portable handset and headset devices, which use a number of microphone configurations to receive acoustic signals of an environment. The microphone configurations include, for example, a two-microphone array including two unidirectional microphones, and a two-microphone array including one unidirectional microphone and one omnidirectional microphone. The communication systems also include Voice Activity Detection (VAD) devices to provide information of human voicing activity. Components of the communications systems receive the acoustic signals and voice activity signals and, in response, automatically generate control signals from data of the voice activity signals. Components of the communication systems use the control signals to automatically select a denoising method appropriate to data of frequency subbands of the acoustic signals. The selected denoising method is applied to the acoustic signals to generate denoised acoustic signals when the acoustic signal includes speech and noise.
