摘要:
A process for the preparation of LH-RH derivatives, characterized by subjecting a solution of an LH-RH derivative to both treatment with a synthetic methacrylic resin adsorbent and that with a synthetic aromatic resin adsorbent. According to this process, the formation of by-product impurities including racemates of LH-RH derivatives can be suppressed and such impurities can be effectively removed, which enables the production of LH-RH derivatives having extremely high quality. Further, the process attains satisfactory purification effectively through the two treatment steps and can give LH-RH derivatives efficiently in high yields by easy operations not involving troublesome solid-liquid separation.

A viscoelastic body is interposed between a vibrating membrane vibrating in association with a piezoelectric vibrator composed of a piezoelectric element and a base and a support member supporting the vibrating membrane. The viscoelastic body attenuates vibration transmitted from the support member to the vibrating membrane and converts vibration of the vibrating membrane in the surface direction parallel to its main surfaces to vibration of the vibrating membrane in the direction nearly perpendicular to the surface direction. The vibrating membrane is annular with an opening at the center, and the base is joined to the vibrating membrane coaxially with opening.

The holding ribs (11) are biased and held on the mounting hole inner peripheral surface (53) with the female connector (10) fitted to the panel (50).
摘要:
A piezoelectric element of the piezoelectric pump is driven by the output signal of an amplifier that takes as input a signal that is generated by a sine wave oscillator of the same frequency that drives the piezoelectric element. The amplifier is driven by a high voltage obtained by conversion from a low-voltage power supply by a voltage-boosting converter, whereby the piezoelectric element is driven by a low-frequency sine wave of high voltage. The frequency of the sine wave oscillation is further adjusted by a signal from a first control circuit at the time of activation. In addition, the amplitude of the sine wave oscillation is adjusted by the output signal of a second control circuit that takes as input a signal from temperature sensor for sensing the temperature of the heat-generating body.
