    摘要: A buried structure avalanche multiplication photodiode (APD) is provided with a surface level difference between the multiplication region and guard ring region. The APD has a so-called separated absorption and multiplication region structure comprising an n-InGaAs light absorbing layer and an n-InP multiplication layer. The surface level difference is provided by selective growth of the layer in which the guard ring is formed or selective removal of the layer over the multiplication region. In the APD, the pn junction is level throughout the multiplication region and guard ring region or is made farther apart from the light absorbing layer in the guard ring region than in the multiplication region, and a significant reduction of dark current due to tunneling current in the InGaAs layer and/or InGaAsP layer is obtained. Moreover, the breakdown voltage difference of the pn junction in the multiplication region and the guard ring region has also been increased.

    摘要: A pressure regulating valve includes a device body and an actuator. The device body includes a valve seat member, a valve, which is capable of closing the first opening of the valve seat member, an urging member, which urges the valve toward the valve seat member, a piston arranged opposite to the valve across the valve seat member, an actuator, which adjusts the position of the piston, and a protrusion provided on at least one of the piston and the valve. When the tip end of the protrusion comes into contact with the piston or the valve, the second opening of the second fluid passage is closed. When the tip end of the protrusion is not in contact with any of the piston and the valve and the second opening is opened, the second fluid passage is in communication with the pressure regulation chamber.
