Patent JP-2003529937-A (JP)
IPC: H01L21/8234
Filed: 2001-03-20
Abstract: The invention relates to an essentially discrete semiconductor device comprising a semiconductor body (10) having a first, preferably bipolar, transistor (T1) with a first region (1) forming a collector (1) of T1, and a second, preferably also bipolar, transistor (T2) with a second region (2) forming a collector (2) of T2, which transistors (T1, T2) are in a cascode configuration wherein the collector (1) of T1is connected to the emitter (4) of T2. Such a device cannot suitably be used in a base station for mobile communication. According to the invention, the first region (1) and the second region (2) are positioned next to each other within a semiconductor region (5), a part of which situated below the first region (1) is provided with a higher doping concentration at the location of T1. In this way, T1 has a low collector-emitter breakdown voltage and a high cutoff frequency, whereas for T2 said voltage and frequency are, respectively, high(er) and low(er). The resultant device is very suitable, on the one hand, for a high voltage application, for example 28 V, and a high power application, for example 100 W and, on the other hand, the device can still operate at a very high speed and hence is very suitable for the above application. Moreover, the device can be manufactured very easily using a method according to the invention. Preferably, the device is rendered suitable for surface mounting, and the semiconductor body is attached to an isolating substrate (20), while the parts thereof that are situated outside T1 and T2 are removed.

Title: ビデオ圧縮方法
IPC: H04N7/50
Filed: 2001-04-13
Abstract: (57)【要約】
Ｂ−フレームの概念は、ＭＰＥＧビデオ圧縮器に高符号化効率を与える。しかしながら、Ｂ−フレーム符号化は、ＭＰＥＧ符号化器の複雑さをおおよそ２倍にする。このために、Ｉ−フレームとＰ−フレームのみを発生するＭＰＥＧ符号化器が、開発された。これらは、複雑さは少ないが、しかし、効率的でない。そのような”ＩＰＰ符号化器”の効率を改善するために、選択されたＰ−フレームは、他のＰ−フレームよりも粗く量子化され、例えば、従来の量子化ステップサイズに１．４を乗じる。この結果は、低品質で符号化された孤立したフレーム（”仮想Ｂ−フレーム”）となるが、全体の知覚的品質は影響を受けない。後続のフレームが低品質のフレームを参照して符号化されても、粗い量子化によって得られたビットレートの利得は、後続のＰ−フレーム内で失われない。

Abstract: <P>PROBLEM TO BE SOLVED: To propose a foam type ink tank equipped with a part to be detected which can correctly detect that ink runs out.  <P>SOLUTION: A sub ink chamber 30 is formed between a main ink chamber 5 and an ink take-out hole 7 of the foam type ink tank 1. When an amount of the air entering the sub ink chamber increases, reflecting faces 52a and 52b of a rectangular prism 52 which have been an ink interface return to reflecting faces and can accordingly detect an ink end. A foaming inhibitor and/or an antifoamer is injected inside the sub ink chamber 30 to supersaturate ink, and therefore an amount of bubbles to be generated in the sub ink chamber 30 is reduced. Generated bubbles disappear in a short time or generated fine bubbles disappear in a short time to gather in a large bubble. Accordingly, such trouble can be eliminated that rear faces of the reflecting faces 52a and 52b are kept covered with the ink held between the bubbles and a reflecting state of the reflecting faces 52a and 52b is unchanged in spite of an ink level decrease, resulting in a failure in detecting the ink end.  <P>COPYRIGHT: (C)2003,JPO
