Abstract: A linear actuator using a screw mechanism is provided which can be made free from play and can operate in a smooth fashion without involving any unacceptably rigorous tolerance control. An external thread of a screw rod is in threading engagement with an internal thread of a nut member for converting a rotational movement of the nut member into a linear movement of the screw rod, and a localized region of relatively tight fit is provided in the threading engagement.

Abstract: A magnetooptical recording medium includes a reproduction layer, a first recording layer and a second recording layer. The reproduction layer is a perpendicular magnetic film in both a state of room temperature and a state of temperature rise. In the first and second recording layers, sub lattice magnetic moments of the same kinds of elements constituting the first and second recording layers are oriented in opposite directions. In reproducing operation, an initialization magnetic field is applied to a portion of the recording medium other than a light beam irradiated portion. A direction of magnetization of the reproduction layer is oriented in a stable direction with respect to magnetization of the first recording layer by an exchange coupling effect in a region at a temperature not less than a middle temperature in the irradiated portion. The direction of magnetization of the reproduction laye22r is oriented in a direction of the initialization magnetic field in a low-temperature region. Reproduction of information is effected by detecting a magnetooptical change in light reflected by the recording medium.

Abstract: A combined seal and boot assembly for protectively covering a telescoping connection between two shaft members in a steering shaft assembly includes a cylindrical body portion, a flexible boot portion, and a pair of sealing lips. The body portion is frictionally mounted on the end of the female splined steering shaft member. The flexible boot portion is formed from a plurality of alternating inwardly and outwardly extending corrugations. The sealing lips extend inwardly into resilient engagement with the splines formed on male splined steering shaft member. The metallic band is provided to maintain the resilient engagement with the splines formed on male splined steering shaft member. The sealing lips are urged into engagement with a higher friction portion of the male splined steering shaft member during normal use, wherein only a small amount of relative axial movement occurs between the male and female splined steering shaft members. However, when the male and female splined steering shaft members are telescopically extended by a relatively large amount, the sealing lips are moved axially off of the higher friction portion of the male splined steering shaft member.

Abstract: A messaging unit equipped with a cellular transceiver is attached to a truck trailer located within a communications network. The messaging unit generates a data message in response to the occurrence of a reporting event. Upon generation of a data message, the cellular transceiver transmits the data message over the network via voice or data channels. The data message is received at an MTSO and then routed to a platform, a clearinghouse, or the platform through the clearinghouse. The data message stored at the platform or the clearinghouse is accessed by a host. A data message may be sent over a voice channel of the network subject to a handshake protocol between the messaging unit and the platform. Data messages may also be sent over a data channel of the network by alto ring the mobile identification number (MIN) or electronic serial number (ESN) of the cellular transceiver. Furthermore, data messages may be sent over a data channel of the network by issuing a feature request with appended data digits.

Title: Jet engine fan noise reduction system utilizing electro-pneumatic transducers
Inventor: OLSEN RONALD F
IPC: F02K1/34
Filed: 1995-10-12
Granted: 2005-02-22
Abstract: A jet engine fan noise reduction system. The noise reduction system includes active noise control to suppress fan (15) tone noise of an airplane flyover noise signature. The active noise control includes microphones (1, 11) with acoustic transducers upstream and downstream of the engine fan (15) and fan exit guide vane (16) stage to sense control system errors. Control signals are derived from the fan angular speed or blade passing frequency and the error signal sensed by the acoustic transducers. The control output signals actuate (modulate) air control valves (45) on each side of the fan stage to direct conditioned (pressure and temperature regulated) high pressure primary air flow, thereby producing acoustic cancelling of fan tone noise.
