Abstract: A stimulating section applies stimulation to a living body. A first lead electrode and a second lead electrode are attached on the living body. A first amplifier circuit amplifies potential difference that is evoked between the first lead electrode and the second lead electrode due to the stimulation. A first switch cancels electrical connection between the first amplifier circuit and each of the first lead electrode and the second lead electrode at least while the stimulation is applied. A high-pass filter includes a capacitor (C) and filters a frequency component of an output from the first amplifier circuit that is no less than a predetermined value. A second amplifier circuit amplifies the output from the first amplifier circuit. A second switch stops charging/discharging of the capacitor (C) and decreases a gain of the second amplifier circuit at least while the first switch cancels the electrical connection.

Abstract: A refrigerating apparatus is provided with a cooling unit whose height is greater than width when installed; and a defrosting device for defrosting frost formed on the cooling unit by heat, the defrosting device being in a straight pipe form, wherein the defrosting device is provided in a vertical direction on a side of the cooling unit. By providing the defrosting device in a straight pipe form in the vertical direction on the side of the cooling unit that is long in a longitudinal direction, it is possible to increase the length of the defrosting device and to lower a surface temperature of the defrosting device. Further, as the defrosting device is long, an amount of heat generation is large and defrosting efficiency is high. Moreover, it is possible to manufacture the defrosting device at a low cost as the defrosting device is in a straight pipe form.
