Title: Wireless cross-connected central-type local area network
Inventor: CHEN TZ-HU
IPC: H04B1/38
Filed: 1999-11-03
Granted: 2001-10-21
Abstract: The present invention is a wireless cross-connected central-type local area network, wherein a network system connecting every host computer and the cross-connected peripheral equipments in the local area network by wireless transmission is disclosed. The transmitter and receiver of wireless transmission are used to replace every host computer and its output equipments (such as monitors and printers, etc.) and input equipments (such as keyboards and mice, etc.), so that the host computers and user's input/output connecting devices can be separately disposed, whereby all host computers can be centrally disposed, which not only simplifies the wiring of the local area network and reduces the occupied space and wiring at user's site, but also manages the host computer centrally, so as to effectively achieve the safety protection of control and simplifies the maintenance work of network. More importantly, the wireless transmission connection of the network system disclosed by the present invention is limited to be used in the peripheral equipments with low data transmission rate related to user input/output. Therefore, the transmission speed of the whole local area network does not have to be limited to the speed of wireless transmission, and the convenience of wireless local area network and high speed transmission of wire local area network can both be obtained. Furthermore, the transmission speed can be increased with the improvement of the wire local area network more economically and conveniently.

Abstract: A microelectromechanical (MEMS) device is provided that includes a microelectronic substrate, a microactuator disposed on the substrate and formed of a single crystalline material, and at least one metallic structure disposed on the substrate adjacent the microactuator such that the metallic structure is on substantially the same plane as the microactuator and is actuated thereby. For example, the MEMS device may be a microrelay. As such, the microrelay may include a pair of metallic structures that are controllably brought into contact by selective actuation of the microactuator. While the MEMS device can include various microactuators, one embodiment of the microactuator is a thermally actuated microactuator which advantageously includes a pair of spaced apart supports disposed on the substrate and at least one arched beam extending therebetween. By heating the at least one arched beam of the microactuator, the arched beams will further arch. In an alternate embodiment, the microactuator is an electrostatic microactuator which includes a stationary stator and a movable shuttle. Imposing an electrical bias between the stator and the shuttle causes the shuttle to move with respect to the stator. Thus, on actuation, the microactuator moves between a first position in which the microactuator is spaced apart from the at least one metallic structure. Several advantageous methods for fabricating a MEMS device having both single crystal components and metallic components are also provided.

Title: Power transmission system for four-wheel drive vehicles
Inventor: ARAI KENTARO
IPC: B60K23/08
Filed: 2000-11-28
Granted: 2002-01-11
Abstract: In a power transmission system for a four-wheel drive vehicle, a multiple disk clutch for distributing a proportion of the torque of the front wheels to the rear wheels is provided between a driving shaft which is connected to the front wheels which are main driven wheels and a driven shaft which is connected to the rear wheels which are auxiliary driven wheels. Between the driving shaft and the driven shaft a torque cam mechanism, a hydraulic pump and a bidirectional clutch mechanism are provided, in that order. When the rotational rate of the front wheels exceeds the rotational rate of the rear wheels, the bidirectional clutch mechanism is engaged, a first rotor of the hydraulic pump which is operatively connected to the front wheels and a second rotor which is operatively connected to the rear wheels rotate relative to each other, and a rotational load is generated by a hydraulic circuit. A first cam element and a second cam element of the torque cam mechanism rotate relative to each other as a result of the above-mentioned rotational load so as to generate a thrust force, and this thrust force causes engagement of the multiple disk clutch so as to put the vehicle into a four-wheel drive mode. It is thus possible to decrease the torque transmission capacity of the bidirectional clutch mechanism so reducing its size and cost.
