Patent CA-2278071-C (CA)
Inventor: KOMINE HIROSHI
IPC: H01S3/23

Abstract: A relatively high average power fiber laser system with phase control. The laser system includes a phased array of parallel fiber amplifiers coupled to a common master oscillator. An important aspect of the invention relates to the independently adjustable optical phase modulators for each of the fiber amplifiers. Various methods for phase modulation are contemplated, such as fast spatial light modulators (SLM) as well as in-line fiber phase modulators. Both types of phase modulation utilize a wavefront sensor for deriving feedback signals for phase control. Arbitrary phase profile information can be applied to the phase modulators to synthesize a desired output beam. Thus, the phase controlled fiber amplifier array functions as a synthetic aperture transmitter at optical frequencies. When combined with a beacon phase front sensor for atmospheric beam propagation, the phase modulator can encode phase conjugate information to compensate for atmospheric aberrations. Relative to other high power laser systems, the laser system in accordance with the present invention has lower power supply demand and cooling requirements which results in lower weight, volume and cost. The use of the fiber laser system in accordance with the present invention also permits greater flexibility in packaging with fewer discrete optics and a relatively simpler optical system design and well as being amenable to mass production.

Abstract: In views of a disadvantage that in a conventional method for localization of sound image in stereo listening, the amount of software is increased and the scale of hardware is enlarged, this invention has been achieved to solve such a problem and intends to provide a processing method for audio signal to be inputted from an appropriate sound source capable of higher precision localization of sound image than the conventional method. When a sound generated from an appropriate sound source SS is processed as an audio signal in the order of inputs on time series, the inputted audio signal is transformed into audio signals for the left and right ears of a person and further each of the audio signals is divided to at least two frequency bands.      Then, the divided audio signal of each band is subjected to a processing for controlling an element for a feeling of the direction of a sound source SS and an element for a feeling of the distance up to that sound source, which are appealed to person's auditory sense and outputting the processed audio signal.

Abstract: A grain storage bin has a circular bin floor structure and a cylindrical bin wall upstanding from the floor. A bin aeration system includes a perforated air discharge tube mounted diametrically across the bin supported on a frame above the floor from one side with an air supply duct for supplying air from a fan through the wall. The floor structure is divided diametrically into two separate half sections. A discharge duct extends from a feed opening at a center of the bin horizontally under the horizontal support surface to a discharge outside the wall of the bin with a belt having an upper run along the duct. An alternative discharge includes a discharge duct extending from a feed opening adjacent a center of the bin upwardly and outwardly through an opening in the wall of the bin at a height spaced upwardly from the floor structure and a base member extending from the horizontal support surface to the duct and defining two side walls each arranged on a respective side of the duct and extending from the duct downwardly and away from the duct such that the interconnection with the base and support surface is wider than the duct and tends to shed the material outwardly away from and an area underneath the duct onto the floor.

Abstract: A method for forming a structural panel such as for a bridge deck includes providing a first and a second sheet formed by fibers and settable resin and laminating the sheets with a plurality of parallel side by side connection members. The connection members are formed by filament winding around a core using primarily a large wind angle followed by a final shallow angle of wrap. The connection members are triangular in cross section and each is inverted relative to the next so that the sides are in contact. The connection members are connected together while the resin is uncured so that during lamination they cure together to allow integration of the resin, close matching of the shapes so that the resin at the junction remains thin and intermingling of the filaments. The connection members are dry wound on a core and the resin is applied by infusion. The core carries reinforcing members to tailor strength as required along the length of the member. The panels are arranged side by side to form a bridge deck and are connected edge to edge with suitable center connection at the crown and suitable curbing at the sides.

Granted: 2008-11-18
Abstract: A support arm has a support structure and an arm structure connected to the support structure through a pivotal connection for pivoting about a horizontal axis. A device is provided for adjusting the elevation of the arm structure by pivoting it about the horizontal axis. A support base is connected to the arm structure through a pivotal connection for pivoting relative to the arm structure about an axis that is parallel to the horizontal axis. A support member is connected to the suppor t base through a pivotal connection for pivoting about a vertical pivot axis, and auxiliary structure such as an air extraction arm may be connected to the support member. A linkage between the support base and the support structure maintains the pivot axis of the support base parallel to a vertical axis as the elevation of the ann structure is adjusted, and avoids the auxiliary structure from swinging under the influence of gravity to a neutral position different from that desired by an operator.
