摘要:
In a compound semiconductor device constituting a field effect transistor having a buried p region 3, a channel region 4 is formed thin and highly doped by n-type impurity, and the buried p region 3 is formed shallowly and highly doped by p-type impurity to compensate the highly doped channel region 4. In order to prevent a leakage current between the highly doped buried p region 3 and a gate electrode 5, a low concentration p-type impurity region 2 is formed on both sides of the highly doped buried p region 3 to thus prevent a current flow via a portion other than a channel region. Accordingly, there can be provided the compound semiconductor device including an FET which is able to suppress both the deterioration in the pinch-off characteristic and the leakage current between neighboring elements due to p-type impurity conduction other than a channel in an FET which has a high concentration and thin active layer, while suppressing the short channel effect.

In order to improve read stability, a printing condition is set based on not visual read of a user, but read with an optical information reading apparatus. A printing quality evaluation apparatus includes: an image acquiring section that acquires an image; a symbol extracting section that extracts the symbol in which the printing quality can be evaluated from the captured images acquired by the image acquiring section; a printing quality evaluation section that evaluates the printing quality of the symbol extracted by the symbol extracting section; an identification information recognition section that recognizes the identification information identifying each printing condition of the symbol; and an evaluation output section that outputs the identification information, which is recognized by the identification information recognition section, and an evaluation result of the printing quality of the printing quality evaluation section according to the symbol extracted by the symbol extracting section.

There is provided an illumination setting support apparatus that enables a user to easily set an optimal lighting pattern while visually checking. A schematic diagram of the illumination unit is displayed in the setting screen, so that clicking on a desired area inside this schematic diagram allows the arbitrary area to be selected from eight areas in the circumferential row of the “outermost circumference” of the external illumination unit. Lighting pattern information is transmitted to a bar code reader and is transferred to the external illumination unit. Imaging is performed while executing illumination control in accordance with the lighting pattern to thereby immediately display a live image on a PC.

Quality of a code provided in a test piece of a work is evaluated, using a sample processing function of a marker that gives the code to the work to present suggestion for setting of a processing condition to a user. Images picked up by a bar code reader are taken in to create a list of readable codes from these picked-up images, and images of these readable codes are displayed in a list. Tuning processing is performed to all the listed-up codes. In this tuning processing, the reading is tried while changing brightness, and a barometer of readability (easiness of decoding) in each of the reading trials is found to calculate a score indicating a level of reading stability based on a value of integral of this barometer, and this score is displayed as a numeric value and in a graph.

Reading result information about whether bar code information has been able to be read normally in a scanning cycle unit is stored in association with a plurality of locations and information on a condition set upon reading. When it is determined, based on stored reading result information which is obtained in an immediately previous scanning cycle, that bar code information in an identical relative location in the immediately previous scanning cycle has been able to be read normally, information on a condition set upon reading in the immediately previous scanning cycle is read. When it is determined that bar code information has not been able to be read normally, information on a condition that differs from information on a condition set upon reading in the immediately previous scanning cycle is set.
