Title: Insulated bipolar transistor and its manufacture
Inventor: TANBA AKIHIRO
IPC: H01L29/739
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To provide an IGBT which has the characteristic of a low ON voltage and a low saturation current. SOLUTION: In a trench gate type IGBT, a tapered groove sloped on a p-type base 14 region side is provided to form a trench gate 10 therein. An oxide film 11 which is wider than an opening part and has a thickness equal to that of a gate oxide film 11' is formed at the bottom surface of the groove. Also, electrons flowing into a n-type base 15 through a reversal layer formed in the p-type base 14 from an emitter 12 in the ON state are made to flow into the whole region of the n-type base 15 through an electron accumulating layer inside the n-type base 15 where electrons are produced under the gate oxide film 11' or the oxide film 11 at the time of the operation of a rated current in which a collector voltage is low, so that the resistance of the base 15 is reduced, thereby being able to realize a low ON voltage.  On the other hand, when the collector voltage is increased and the electron accumulating layer disappears, the flow of electrons is limited mainly to the lower part of the p-type base 14, and the resistance of the n-type base 15 is increased, so that a low saturation current may be realized.

Inventor: AMAZAWA TAIJI
IPC: H04B1/712
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To reduce errors in symbol data even when high noises are contained by performing movement averaging processing to an arriving diffusion modulate signal. SOLUTION: A correlation part 1a extracts waves delayed on different transmission lines from a received base band signal and outputs received symbol data S1a reversely diffusing these waves. A temporary propagation path estimation part 2a finds an influence exerted upon the transmission line while using predetermined known data and outputs a temporary propagation path estimated value S3a through a Gaussian interpolation expression. A temporary discrimination part 3a sends temporary propagation path information removed received symbol data S5a from the received symbol data S1a to a temporary discrimination part 3b of another processing path and performs temporary discrimination based on the mutual synthesization with symbol data on the other path.  In this case, corresponding to temporarily discriminated symbol data S4a and S4b and received symbol data S1a and S1b, move average parts 4a and 4b estimate propagation path information by removing the influence caused by noise components through smoothing.

Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To structure the system which accurately transmit information such as odds information from a racecourse by using a teletext signal. SOLUTION: A file read part 3a reads information in a teletext mixer 2 out of a file on a server 1. The read information is converted by a message generation and transmission part 3c into a teletext signal, which is sent out to a display device 4, etc., to transmit the odds information, etc., through display. An information contradiction detection part 3b of the teletext mixer 2 sequentially monitors the sequential information read in from the server 1 to detect whether or not there is contradiction. For example, the number of perfecta tickets of a horse number 5 is read out and data on the odds value of the perfecta of the horse number 5 is read out. If the ticket number data which is read first is not 0 and odds data is '0.0', the odds data has contradiction, so it is judged that the file on the server 1 is abnormal and a message of the file is neither generated nor transmitted.
