Abstract: The invention intends to provide a technique that achieves a sufficient phase margin with ease. The circuit includes a power supply circuit that is formed with a phase compensating resistor and a phase compensating capacitor, between a second input terminal of a differential amplifier and a low supply voltage. Thereby, the first pole frequency in the overall gain is determined by the first pole frequency in the voltage-dividing resistor stage in the Bode diagram for the pole/zero compensation, which is shifted to a lower frequency. Also, the zero point cancels the first pole frequency in the differential amplifier stage, which reduces the phase delay to secure the phase margin.

Abstract: An impact handle for a shovel and other tools to assist the user or laborer in digging and/or moving material such as dirt or snow, or other compacted materials. An impact handle with a shovel attachment would have similar physical features as generic shovels on the market today. However, the impact handle includes an impact generator within the handle. As a user or operator applies his/her foot-pressure on the foot actuator located at the top of the scoop or blade, the impact generator using electro-magnetic principles produces impulses of 1 to 10 hertz of downward blows. These impulses reduce the effort required by the operator to force the tool scoop or blade to penetrate the material being excavated. The impact handle dramatically reduces time required to complete hand excavation projects. The impact handle can also be used, but is not limited to, to reduce the time required for chiseling, scraping, prying, nail pulling and carpet-stretching.

Abstract: A high quality gray scale (monochrome) image in which influences of “recorded color deviation” and “color transition” are suppressed is formed even in the case of a slightly uneven discharge amount. When a gray scale (monochrome) mode is set, in the entire range of a luminance signal, density signals corresponding to achromatic dots and small chromatic dots respectively are generated based on the luminance signal so that the density signal corresponding to the achromatic dots has a greater value than that of the density signal corresponding to the small chromatic dots. Accordingly, even a slight “recorded color deviation” that occurs when the achromatic dots are recorded can be corrected by the small chromatic dots having a hue opposite to the direction of color deviation, and a high quality gray scale image in which influences of “recorded color deviation” and “color transition” are suppressed can be formed.
