    摘要: A method of producing sustained-release microcapsules containing a biologically active substance from an W/O emulsion comprising an inner aqueous phase containing said biologically active substance and an external oil phase containing a biodegradable polymer, characterized in that microcapsules formed on microencapsulation of said biologically active substance with said biodegradable polymer are heated at a temperature not lower than the glass transition temperature of said biodegradable polymer but not so high as to cause aggregation of the microcapsules. This method enables the production of very useful sustained release microcapsules adapted to release a bologically active substance at a calculated rate over a protracted time period starting immediately following administration without an initial burst within one day following administration.

    摘要: Provided is a light adjusting noise reduction circuit in which the vibration noise accompanying turning ON/OFF of a piezoelectric transformer. A full bridge circuit is controlled by a full bridge drive circuit so as to switch an input voltage (VB1) from an input voltage source and outputs it to a low pass filter. The output from the low pass filter is supplied to a piezoelectric transformer. The output current (IO) from the piezoelectric transformer is supplied to a discharge tube. Each of FET of the full bridge circuit has a drive frequency decided by a voltage control type oscillator. The full bridge circuit is connected to a duty variable circuit and a peak value control circuit. The peak value control circuit forms a rise and a fall of a waveform to be (1−cosωt).
