Title: Junction type field-effect transistor
Inventor: KANAMORI SHIYUUJI
IPC: H01L29/80
Filed: 1982-05-13
Abstract: PURPOSE:To suppress lowering of the yield rate for a J-FET to the minimum by a method wherein a check pattern, having a gate aperture of the width same as that of a normal element part, is provided. CONSTITUTION:A gate region of check pattern is formed in lattice or slit form. This region has the same shape and area as the gate part of a normal J-FET, and if the normal part is imperfect at the time of manufacture, the check part is also turned to imperfect. Therefore, when punch-through voltage is checked by adding bias on the two gates 1 and 4 of the pattern, the voltage is turned open if formation is incomplete, and the unsatisfactory one is rejected while the manufacturing process is in progress. According to this constitution, the lowering of the J-FET for high frequenty, for which gate length will be submicronized, can be suppressed to the minimum.

IPC: G06K9/68
Filed: 1990-03-30
Abstract: PURPOSE:To accurately identify patterns by allowing a correlation optical system to calculate the correlation between a reference pattern group displayed in a reference pattern set display area and one of the input patterns of predicted input pattern groups including the reference pattern group. CONSTITUTION:The correlation between the reference pattern group displayed in the reference pattern set display area and one of the input patterns of the predicated input pattern groups including the reference pattern group are calcu lated by the correlation optical system using the reference group. If a alculated optical correlation output is different from a desired one, a display output corresponding to the input pattern is added to a display output from the position of a reference pattern where a stronger correlation output is desired, on the other hand, a display output corresponding to the input pattern is subtracted from a display output from the position of a reference pattern where a weaker correlation output is desired, whereas if the difference is negative, a display output from the position is set to the minimum of a display device. This process is carried out with respect to plural input patterns. Thus, even similar patterns can be accurately identified, as well.

Title: Air-fuel ratio controller for internal combustion engine
Inventor: KAWANABE TOMOHIKO
IPC: F02D41/00
Filed: 1985-04-16
Abstract: PURPOSE:To prevent engine output from dropping at highland, by compensating the desired air-fuel ratio set up according to the specified engine running parameter in proportion to size of atmospheric pressure. CONSTITUTION:Suction air to an engine 5 is also supplied through a secondary suction air supply passage 8 provided with a solenoid on-off valve to be driven for opening or closing according to a command out of a control circuit 20, besides via a carburetor 3.
