Abstract:
A silicon carbide semiconductor device includes: a semiconductor substrate including first and second gate layers, a channel layer, a source layer, and a trench; a gate wiring having a first portion and a plurality of second portions; and a source wiring having a third portion and a plurality of fourth portions. The trench extends in a predetermined extending direction. The first portion connects to the first gate layer in the trench, and extends to the extending direction. The second portions protrude perpendicularly to be a comb shape. The third portion extends to the extending direction. The fourth portions protrude perpendicularly to be a comb shape, and electrically connect to the source layer. Each of the second portions connects to the second gate layer through a contact hole.
Abstract:
Methods and apparatus are disclosed for changing the bandwidth or other traffic characteristic of an established packet call in response to an identification of the requirements of the call. For example, in response to the detection of a type of call, such as a fax or modem call, ATM signaling is performed with peer signaling agent(s) located in the ATM network to increase the bandwidth of an already established portion of a call through the ATM network. This signaling typically includes sending a call modify request message and receiving a modify acknowledgement message, with these messages typically, but not limited to, conforming with a Q.2963 signaling standard.

Abstract:
A method that sends ATM source identification and an ATM-TDM correlation tag from an ATM source gateway to a telephony signaling control network; and then receives at an ATM destination gateway the ATM source identification and the ATM-TDM correlation tag as sent from the telephony signaling control network; and then sends the ATM-TDM correlation tag from the ATM destination gateway to the ATM source gateway to establish a connection between the ATM destination gateway and the ATM source gateway.
Abstract:
Methods for preparing microparticles having reduced residual solvent levels. Microparticles are contacted with a non-aqueous washing system to reduce the level of residual solvent in the microparticles. Preferred non-aqueous washing systems include 100% ethanol and a blend of ethanol and heptane. A solvent blend of a hardening solvent and a washing solvent can be used to harden and wash microparticles in a single step, thereby eliminating the need for a post-hardening wash step.

The invention relates to new methods of enzymatic synthesis of polymers such as polyorganosilicones and polyesters, and new polymers made by these methods.
Abstract:
A silicon carbide semiconductor device includes: a semiconductor substrate including a base substrate, a first semiconductor layer, a second semiconductor layer and a third semiconductor layer, which are laminated in this order; a cell portion disposed in the semiconductor substrate and providing an electric part forming portion; and a periphery portion surrounding the cell portion. The periphery portion includes a trench, which penetrates the second and the third semiconductor layers, reaches the first semiconductor layer, and surrounds the cell portion so that the second and the third semiconductor layers are divided by the trench substantially. The periphery portion further includes a fourth semiconductor layer disposed on an inner wall of the trench.
Abstract:
Text is interleaved and transported along with media data over the same real-time Internet Protocol (IP) media transport session. A network processing device identifies text characters corresponding with text signaling. The identified text characters are formatted into text packets and sent over the same real-time IP media transport session used for real-time media transport. The media transport session can identify the sequence that the text characters are transmitted and can specify a maximum character transfer rate.
