Title: Power mosfet
Inventor: TSUZUKI YUKIO
IPC: H01L29/78
Filed: 2001-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a MOSFET having such a device structure which is hardly destroyed. SOLUTION: The impurity concentration in an n--type epitaxial layer 2 is kept constant to a prescribed depth from the principal plane. From the prescribed depth on, the impurity concentration is increased with linear gradient. Due to this structure, electric field distribution can be smoothly changed in the n--type epitaxial layer 2 and a drain current value, at which a MOSFET comes to have a negative resistance can be set higher than in the conventional method. Even if the drain current of part of a plurality of MOSFETs is higher than those of the other MOSFETs, since the MOSFETs having a higher drain current will hardly enter negative resistance, increase in an allowable current value until the MOSFETs come enters negative resistance, that is, the resistance to avalanche can be set high.  Consequently, the dain current is prevented from becoming a large current in the part of the plurality of MOSFETs, making the MOSFETs have a device structure which is hardly destroyed.

IPC: G06T7/00
Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To solve the problem of recognition rate decreasing, as threshold is increased and misrecognition rate increases, as the threshold is decreased in template matching, using the thresholds. SOLUTION: In calculating matching rate for each binary of binarized image data with a template and determining matching, on the basis of the coinciding rate, non-match determination is performed, when both the coinciding rates are close to the respective thresholds.

Furthermore, match determination is performed, according to positional relationship on a two-dimensional plane of a threshold function using each matching rate for the binary as the variable with the calculated matching rate. Thereby a case to determine as 'a general image' and that to determine as 'a specific log' can be determined clearly and a high recognition rate and a low misrecognition rate can be realized at the same time.
