摘要： A photodiode (11) of a receiver (10) outputs a current signal having a value that corresponds to the optical power of a received optical signal. A transimpedance amplifier (12) amplifies the current signal output from the photodiode (11), converts the current signal to a voltage signal, and further outputs the voltage signal that is converted from the current signal. A current detection circuit (17) generates a current having a value larger than that of the current signal output from the photodiode (11). A feedback resistor (16) changes a gain of the transimpedance amplifier (12) based on magnitude of the current generated by the current detection circuit (17).

摘要： An object of the present invention is to provide an osteogenic biomaterial which achieves long-term sustained release and localized functional expression of a substance which promotes the formation of bone tissue. The present inventors have found out that a nanogel efficiently encloses an osteogenesis promoting substance to suppress the substance from diffusion into blood, and that the nanogel functions as a carrier for local administration of the osteogenesis promoting substance. Furthermore, they have found out that the osteogenesis promoting substance-containing nanogel can be cross-linked with a water-soluble polymer to allow sustained release of the osteogenesis promoting substance at a local area over a long period of time. Based on these findings, the present invention was completed. The osteogenic biomaterial of the present invention which contains the osteogenesis promoting substance and the nanogel shows osteogenesis promoting activity over a long period of time, and can be used as a preventive and therapeutic agent against bone diseases.

摘要： A frequency converter which is capable of rejecting unnecessary signals generated by image signals. The frequency converter has first and second local oscillation circuits which generate local oscillation signals whose frequencies are the same and whose phases are different by 90 degrees from each other. The converter further includes two mixer circuits, and a hybrid coupler. The mixer circuits generate two unnecessary signals whose phases are different by 90 degrees from each other. The hybrid coupler delays one unnecessary signal by a quarter of a wavelength to generate two unnecessary signals whose phases are different by 180 degrees from each other, so that they are cancelled by each other.

摘要： A photodiode converts an optical signal output from a laser diode to a current signal, and a current-to-voltage conversion circuit converts the current signal to a voltage signal. A comparison amplifier compares the voltage signal with a reference voltage to control the current flowing from a variable current source and increases or decreases a bias current for driving the laser diode. The current-to-voltage conversion circuit comprises a resistor and a variable current source that are connected in parallel. Therefore, it is possible to change the bias current without changing the resistance value of the resistor and to avoid limiting the dynamic range of the optical signal that is output. In addition, since the resistance value of the resistor does not change, the loop gain does not change, thereby stabilizing the control operation.
