Abstract: An apparatus for exerting an ultrasound beam on a sample solution containing particles to be concentrated, separated or arranged permits arbitrarily controlling the spatial distribution of the potential energy created by the ultrasound beam and concentrating, separating or periodically arranging the particles. Irradiation ultrasound sources (631, 632) for generating ultrasound beams are provided on a chamber holding said solution to create an ultrasonic intensity distribution for producing a position potential energy distribution used to exert on each particle a force forwarded in a predetermined direction or a force staying at a predetermined region. Thus, a specific spatial distribution of the potential energy can be realised by ultrasound beams each having a specific intensity, a specific frequency and a specific phase or by an ultrasound beam formed by the mutual superposition of such beams. Further, at least one suction hole (671) for recovering separated solvents or particles is defined in a wall surface of the chamber, which is orthogonal to the flow of the sample solution.

Abstract: Colorwiping and dynamic positioning of subtitles for a video image is achieved by encoding and decoding the subtitles separately from the video image. At the encoder (Fig. 7), subtitles are generated (55) for each respective video image. Colorwiping is performed by changing the color of the subtitles at a certain location in the video image. At the decoder (Fig. 2), a buffer (22) stores the subtitles along with subtitle decoding information. A controller (35) precisely times a reading operation of the buffer to read out the subtitles during a real time display of the respective video image; and colorwiping is performed by changing the color of a portion of the subtitles at a location indicated by the subtitle decoding information. Dynamic positioning of the subtitles is achieved by delaying the time the controller executes the read operation. When the decoding technique is repeated for a number of frames, the viewer senses motion as the colorwiping and positioning gradually changes.

Abstract: A method of forming fabric for making foam-in-place molded articles such as preferably seat cushions. A film (28) is secured to a frame (50) and tacked by adhesive to a piece of fabric (26), not secured to the frame, that forms the outer covering of the seat cushion for permitting the fabric to move relative to the film during forming to enable fabrics which cannot stretch a considerable amount to be used. To form the fabric, the film and fabric are placed in a female mold (94) and the film and fabric are drawn into a cavity of the mold and against a contoured surface in the cavity forming a recess in the film and fabric. To counteract compressive stresses in the fabric during forming, the frame can have one or more fabric tensioners that selectively apply tension to the fabric during forming. To mold the cushion, a foam (120) is poured into the recess and allowed to cure until it hardens into a foam core and bonds with the film. Preferably, to fix the shape of the film and fabric to that of the contoured surface of the mold cavity to enable the foam to be poured into the recess without requiring the film and fabric to be supported by the mold, the adhesive, film and fabric are heated before forming to make them pliable and cooled after forming to fix their shape to substantially conform to that of the contoured surface of the mold cavity.

Abstract: L'invention concerne un procédé pour transformer l'enthalpie de réaction libre accumulée dans les substances renfermant de l'hydrogène, notamment le glucose et autres réserves 2H chimiques, conjointement avec l'oxygène O2 de l'air, en l'énergie d'un champ électrodynamique dans un convertisseur chimicoélectrique, sur la base de la réaction (2H + O } H2O). Lors de la réduction en deux étapes de O2, on utilise l'enthalpie de réaction des deux étapes. L'enthalpie de réaction libre de la première étape qui donne H2O2 puis l'accepteur O proprement dit est de préférence libérée par des halogènes et/ou des pseudohalogènes par réaction de l'O2 avec des composés contenant de l'hydrogène, et transférée par le ou les produits de réaction dans la séquence de réaction pour décomposer le glucose en paires (4H + CO2). Quant à l'enthalpie de réaction de la deuxième étape, qui se fonde sur H2O2, elle est utilisée pour la réaction chimicoélectrique. L'accepteur O proprement dit est prélevé sur H2O2 de préférence par un support à base d'acides capables de liaison peroxide, puis transporté vers l'électrode positive du convertisseur chimicoélectrique. La transformation chimicoélectrique sert au chargement électrique d'une molécule et/ou d'une structure obtenue par synthèse, ayant la fonction d'une batterie activable en cas de besoin.

Abstract: A bus controller controls an access to a bus connected to a first device which operates in synchronization with a first clock signal and a second device which operates in asynchronization with the first clock signal. The controller includes a detector. The detector receives an access request from a central processing unit which operates in synchronization with a second clock signal different from the first clock signal to detect whether the access request represents an access to the first device or an access to the second device. The controller further includes an access controlling signal generator. The access controlling signal generator generates a first access controlling signal for controlling an access of the first device to the bus in synchronization with the first clock signal and for supplying the first access controlling signal to the first device, in a case where the access request represents the access to the first device. The access controlling signal generator generates a second access controlling signal for controlling an access of the second device to the bus in synchronization with the second clock signal and for supplying the second access controlling signal to the second device, in a case where the access request represents the access to the second device.

Abstract: The method uses a memory programmable control (SPS) on a machine. The machine has actuators driven by the programmable control (SPS) for causing the machine actions as well as sensors for outputting machine state signals. Each successive actuator operation is triggered independent of whether the machine action caused by the previous actuator operation has finished. The output time point of a successive actuator operation signal may be derived from the output time point of a previous actuator operation signal. The function time for carrying out the machine action triggered by the actuator operation may be determined for a new determination of an actuator operation signal for the next cycle repetition. An arrangement for controlling the machine includes a state review device (20) connected between the memory control (SPS) and the machine (30). this device receives the output actuator operation signals and the machine state signals.

Abstract: A method of switching a communication channel when a
mobile station (106, 107, 108) moves from one service area (109,
110, 111) to another service area is disclosed. The mobile station
determines a difference between the transmission phase of a frame
synchronizing signal received from a first base station (103, 104,
105) currently holding a communication channel with the mobile
station and the transmission phase of a frame synchronizing signal
received from a second base station expected to newly set up a
communication channel with the mobile station. The mobile station
sends phase difference information representative of the above
difference to the first base station via the communication channel.
The first base station having received the phase difference
information transfers the information to the second base station,
causing it to correct the phase of data thereof to be sent to the
mobile station. This successfully implements soft handover while
guaranteeing the phase synchronization of frames sent from the
two base stations.
