Abstract: A microwave processing device of the present disclosure is provided with a heating chamber, a microwave generating unit, an amplifying unit, a power supply unit, a detecting unit, a control unit, and a storage unit. The microwave generating unit generates microwave having an optional frequency in a predetermined frequency band. The amplifying unit amplifies an output level of the microwave. The power supply unit radiates the microwave amplified by the amplifying unit into the heating chamber as incident electric power. The detecting unit detects reflected electric power, which returns to the power supply unit from the heating chamber, from among the incident electric power. The control unit controls the microwave generating unit and the amplifying unit. The storage unit stores a value of the reflected electric power, together with a frequency of the microwave and an elapsed time from the start of heating.

Abstract: A high frequency heating apparatus (1A) includes the following components: a first electrode (11) that is flat; a plurality of flat second electrodes (12) that are flat; a high-frequency power supply (20); a matching unit (30); a controller (40); and an electric field regulator (50). The second electrodes (12) are placed opposite to the first electrode (11). The high-frequency power supply (20) applies a high-frequency voltage to the first electrode (11). The matching unit (30) is placed between the first electrode (11) and the high-frequency power supply (20), and is impedance-matched with the high-frequency power supply (20). The controller (40) controls the high-frequency power supply (20). The electric field regulator (50) individually adjusts the electric field strengths in a plurality of regions located between first electrode (11) and the second electrodes (12). This aspect can reduce uneven heating.

Abstract: A progressive power lens pair is provided with an object-side surface and an eyeball-side surface of the right-eye lens and an object-side surface and an eyeball-side surface of the left-eye lens which are set by ensuring that ADDR1?ADDR2 and ADDL1?ADDL2 take values different from each other, when prescribed additional power for the right-eye lens and prescribed additional power for the left-eye lens are equal to each other; and prescription information for the progressive power lens pair indicates: that spherical power SR at the right-eye lens and spherical power SL at the left-eye lens are different from each other, that astigmatic power CR at the right-eye lens and astigmatic power CL at the left-eye lens are different from each other, or that an astigmatism axis angle AxR corresponding to the right-eye lens and an astigmatism axis angle AxL corresponding to the left-eye lens are different from each other.

Abstract: A measurement system includes: an image-capturing unit that continuously captures an image of eyeglasses a subject wears; an extraction unit that continuously extracts a mark made on a lens or a frame of the eyeglasses or a contour of the lens or the frame of the eyeglasses; and an amount of change measurement unit that calculates an amount of change in position of the mark or the contour extracted by the extraction unit and, based on the calculated amount of change, measures an amount of change in position of the eyeglasses.
