    • Transistor fabrication includes forming a nitride-based channel layer on a substrate, forming a barrier layer on the nitride-based channel layer, forming a contact recess in the barrier layer to expose a contact region of the nitride-based channel layer, forming a contact layer on the exposed contact region of the nitride-based channel layer, for example, using a low temperature deposition process, forming an ohmic contact on the contact layer and forming a gate contact disposed on the barrier layer adjacent the ohmic contact. A high electron mobility transistor (HEMT) and methods of fabricating a HEMT are also provided. The HEMT includes a nitride-based channel layer on a substrate, a barrier layer on the nitride-based channel layer, a contact recess in the barrier layer that extends into the channel layer, an n-type nitride-based semiconductor material contact region on the nitride-based channel layer in the contact recess, an ohmic contact on the nitride-based contact region and a gate contact disposed on the barrier layer adjacent the ohmic contact. The n-type nitride-based semiconductor material contact region and the nitride-based channel layer include a surface area enlargement structure.

    • A tile roof ridge row vent and the method of its use and construction are disclosed. The ridge row vent is designed for use with either barrel tile or flat tile. The tile roof ridge row vent includes an elongate member having a vertical section and a side section connected to allow air flow therebetween. The vertical section has a lower sealing skirt that extends under the top row of roof tiles and the side section includes plurality of ventilation openings angled downwardly and outwardly to allow air to exit the vent while a filtration media aids in preventing rain or other inclement weather from entering the vent. A second embodiment is shown for use with a single sided or mansard type roof. A third embodiment is shown for use in high wind and hurricane prone areas with an angled roof and includes an external baffle added to the ridge row vent. A fourth embodiment utilizing the ridge row vent with the external baffle is shown for use with a mansard type roof.

    • A fluid valve transmission having an automatic by-pass in neutral on the pump side and automatic brake or by-pass on the driven motor side while in the neutral position. Through holes and channels in the rotor are designed with close openings to open and close smoothly as the valve is turned, one opening as the other closes. All channels in the rotor are full of fluid at all times. The valve positions are designed with neutral midway between forward and reverse. This allows for quick start and stop and forward or reverse changes. Pressure equalization lines in the valve body from the pump and motor lines enter a circumferential channel on the rotor valve. This prevents the rotor from binding in high pressure applications.
    • 一种流体阀传动装置,其具有在泵侧的空档中的自动旁路,并且在处于中立位置时在从动马达侧自动制动或旁路。 转子中的通孔和通道设计有紧密的开口,阀门转动时平稳地打开和关闭,一个开口作为另一个关闭。 转子中的所有通道始终都是流体。 阀门位置设计为正向和反向中间中间位置。 这允许快速启动和停止以及正向或反向更改。 来自泵和马达管路的阀体中的压力平衡管线进入转子阀上的圆周通道。 这防止转子在高压应用中结合。
