摘要： Semiconductor switches, such as thyristors (200), may be light activated by introducing the light into the switch via a groove (216) having a sloped surface to receive the triggering light. The use of a sloped surface increases the surface path length between points of different electrical potential in the groove (216) and, therefore, reduces the likelihood of electrical breakdown on the groove wall (220). In one particular embodiment, a light-activated thyristor comprises a semiconductor anode layer (210), an n-base layer (204), a p-base layer (202) and a semiconductor cathode layer disposed parallel to a thyristor plane. A thyristor axis (222) lies perpendicular to the thyristor plane. A groove (216) having a light refracting side wall extends into the thyristor from the anode layer (210). A portion of the light refracting side wall is disposed non-parallel to the thyristor plane and to the thyristor axis (222), and extends in the n-drift layer (204).

摘要： Biofuels may be produced from algae, and algae may be dewatered, by exposing the algae to shaped pulsed pressure waves. The shaped pulsed pressure waves are produced within the liquid medium containing the algae, and are designed to effectively disrupt the physical structure of the algae in the liquid medium to facilitate the release of biofuel, water, or both. Biofuel is obtained by separating the biofuel from the disrupted algae and liquid medium in any desired manner. Accordingly, the production of biofuel from algae may be performed efficiently, without pre-drying the algae. Dewatered algae is obtained by separating the disrupted algae from the liquid medium in any desired manner. Suitable pressure wave sources include electrohydraulic generators, electromagnetic generators, and piezoelectric generators. A drive pulse supply such as a Marx bank generator may be used to drive these sources to obtain the shaped pulsed pressure waves.

摘要翻译：诸如晶闸管的半导体开关可以通过经由具有倾斜表面的凹槽将光引入开关而被激活，以接收触发光。倾斜表面的使用增加了凹槽中不同电位点之间的表面路径长度，因此降低了在凹槽壁上电击穿的可能性。在一个特定实施例中，光激活晶闸管包括平行于晶闸管平面设置的半导体阳极层，n基极层，p基极层和半导体阴极层。晶闸管轴垂直于晶闸管平面。具有光折射侧壁的凹槽从阳极层延伸到晶闸管中。光折射侧壁的一部分设置成不平行于晶闸管平面和晶闸管轴线，并在n漂移层中延伸。
