    摘要： A monitoring circuit of the present invention provides a monitor signal with which a magnitude of a current flowing across a photodetector, such as a photodiode, can be calculated accurately over a wide temperature range on the basis of a value of the monitor signal. The monitoring circuit of the present invention includes: a current mirror circuit for outputting a monitor current proportional to an input current, the current mirror circuit having an input point for receiving the input current, the input point being connected to a photodetector and a load resistor, which are connected thereto in parallel; and an output circuit for outputting a monitor signal indicating a difference between a monitor electric potential proportional to the monitor current, and an offset electric potential proportional to an offset current which flows across the load resistor concurrently with the monitor current.

    摘要： In order to isolate and purify an endohedral fullerene, a solvent washing was performed using toluene to concentrate the endohedral fullerene in a residual, but endohedral fullerene could not be efficiently purified because impurities other than the endohedral fullerene could not be sufficiently removed. Thus, the endohedral fullerene is isolated and purified by using a solvent such as chloronaphthalene or tetralin having a high solubility for the endohedral fullerene and concentrating the endohedral fullerene in the solvent. The endohedral fullerene isolated and purified by solvent extraction has a cluster structure where the endohedral fullerene is surrounded with empty fullerenes. Thus, this endohedral fullerene is highly stable and is a useful material applicable to various fields such as medical care and electronics.

    摘要翻译： 为了分离和纯化内生的富勒烯，使用甲苯进行溶剂洗涤，以将内嵌的富勒烯浓缩在残留物中，但是由于内部富勒烯以外的杂质不能被充分除去，因此不能有效地纯化内生的富勒烯。 因此，内嵌式富勒烯通过使用对内嵌式富勒烯具有高溶解度的溶剂如氯萘或四氢化萘并将内面富勒烯浓缩在溶剂中来分离和纯化。 通过溶剂萃取分离和纯化的内嵌富勒烯具有簇结构，其中内部富勒烯被空的富勒烯包围。 因此，该内嵌式富勒烯是高度稳定的，并且是适用于医疗和电子等各个领域的有用材料。

    摘要： A peak voltage detector circuit detects a peak voltage of an input voltage. The input voltage is input into a first input terminal of a comparator. A counter circuit counts up a counter value in synchronization with a first clock signal, when a signal output from the comparator is in a first state. The counter circuit counts down the counter value in synchronization with a second clock signal. A digital-analog conversion circuit outputs an output voltage corresponding to the counter value, and the output voltage is input into a second input terminal of the comparator. The first clock signal has a wave period shorter than that of the second clock signal.
