Title: Film bulk acoustic wave device
Inventor: MISU KOICHIRO
IPC: H03H9/56
Filed: 1998-08-04
Abstract: A film bulk acoustic wave device, comprising: a substrate; a bottom electrode formed on one surface of the substrate; a piezoelectric film formed on the bottom electrode; and a first top electrode formed on the piezoelectric film, further comprises a second top electrode having a larger mass load than the first top electrode, and formed on the first top electrode on the piezoelectric film when viewed from the center of the first top electrode, wherein the piezoelectric film has a high-band-cut-off-type dispersion characteristic.        The cut-off frequency of a second top electrode portion piezoelectric film raving a large mass load can be lower than the cut-off frequency of a first top electrode portion piezoelectric film, to thereby trap the energy of the acoustic wave in a region of the first top electrode portion side, so that good performance may be feasible.

IPC: H04B7/185
Filed: 1998-05-01
Abstract: On décrit un système de radiodiffusion et de radiotélécommunication par satellite qui comprend une constellation de satellites ayant des orbites fortement elliptiques et inclinées, dans lequel des satellites restent presque fixes par rapport aux utilisateurs au sol et décrivent une petite boucle dans le ciel autour de l'apogée de l'orbite pendant de longues périodes. Un utilisateur situé au sol équipé d'une antenne directive classique recevra des services de communication continue sans interruption 24 heures sur 24. La petite boucle dans laquelle les satellites sont opérationnels se situe autour de la latitude la plus élevée de l'orbite. Par conséquent il existera une grande séparation angulaire entre les satellites fonctionnant sur l'orbite satellitaire géostationnaire équatoriale (appelée ensuite plus simplement orbite des satellites géostationnaires), ceci permettant un partage complet des bandes de fréquences utilisées par les systèmes orbitaux de satellites géostationnaires, sans provoquer d'interférences entre les deux type de système de réseau satellitaire sans qu'il soit nécessaire d'utiliser des facteurs atténuant les interférences. Les utilisateurs de cette orbite sont capables de voir un service de transmission complètement dépourvu d'interruptions à partir de satellites sans qu'il soit nécessaire d'effectuer de commutation entre les satellites ou sans qu'il existe d'interruption de service.
Patent CA-2289758-A1 (CA)
Inventor: BLOM CLAES
IPC: G02B6/42
Filed: 1998-05-15
Abstract: An optoelectric capsule (1) has a recess (2) at one of its short sides. In the recess a ferrule (4) projects, which contains an optical fiber (4'), which is in contact with an optoelement (1') inside the capsule. The ferrule (4) can come in contact with a similar ferrule (6), which is elastically (10) arranged in the house (8) of a connector (5''). An alignment of the ferrules with each other is obtained by means of a slotted, elastic tube (5). The house of the connector has at its front side a flange (9), which can engage in the recess (2) of the capsule when rotating the house (8). A locking action after rotating the flange 90~ in the recess is obtained by the method that the inner surfaces (3) in the recess (2), that retains the flange (9), have a convex shape whereas the rear surface of the flange has a corresponding concave shape. The connector (5'') can in that way be easily attached to the capsule (1) and detached therefrom. Thereby a capsule is obtained having a simple optical connection not using any integrated pigtail, which could cause problems when handling and mounting the capsule (1) on a circuit board.

Title: Method for preventing windup in pid controllers employing nonlinear gain
Inventor: LAWRENCE RICHARD C
IPC: G05B5/01
Filed: 1998-08-17
Abstract: A method of preventing windup in a PID controller when using a nonlinear gain parameter is disclosed that is used in the PID controller of a process control system. The PID controller is arranged to produce within a current execution cycle a Control Variable (CV) to a device that is controlling a process responsive to an input Process Variable (PV), a setpoint (SP), and a gain parameter (K). The present invention receives the PV, the SP, and the K and generates a proportional, integral, and derivative component of the deviation of the PV from the SP. The components so generated are used to calculate an incremental output CV for the current execution cycle. A current value of gain is next calculated by subtracting the value of the gain for the current cycle from the value of the gain from the previous cycle. Testing for a linear or nonlinear gain parameter is done next and, responsive to a nonlinear gain parameter, a nonlinear gain change component is calculated and added to the incremental output CV. An output CV is generate for the current execution cycle by adding the incremental ouput CV modified by the nonlinear gain change component to the CV value of the previous execution cycle. The accumulated sum of proportional, integral, and derivative components of previous execution cycles are updated with the proportional, integral, and derivative components generated by the current execution cycle.  These accumulated values will be used in calculating the nonlinear gain change component in the next cycle. However, if the testing identifies a linear gain parameter, the nonlinear gain change calculation is skipped and the output CV is generated by adding the incremental output CV to the CV value of the previous execution cycle.

Inventor: HUDDLE JAY
IPC: A23N15/08
Filed: 2000-03-15
Abstract: An apparatus and method for processing a root vegetable, such as a radish. The apparatus includes a hopper, a track, and a cutting mechanism. The hopper includes a reciprocating chute for providing a radish from a plurality of radishes to the track. As the radish travels down the track, the radish is properly .positioned and orientated such that a tip portion of the radish is disposed between spiral threads in the track. If the radish is not properly oriented, air pressure is applied against the radish to remove the radish from the track. If the radish is properly oriented, it reaches the cutting mechanism having a pair of belts that frictionally engage the radish. As the radish travels through the cutting mechanism, the radish encounters a first blade which cuts a bottom portion from the radish. As the radish continues to travel through the cutting mechanism, another pair of belts frictionally engage the top portion of the radish and properly positions the radish for a second blade to cut a top portion from the radish. The processed radish is then expelled from the cutting mechanism onto a conveyor belt for packaging and delivery to the consumer. The method includes the steps of providing a root vegetable, orientating the root vegetable and cutting the top and bottom portion from the root vegetable.
Patent CA-2305707-A1 (CA)
Inventor: ARKOWITZ ROBERT ALAN
IPC: C07K14/82
Filed: 1998-10-08
Abstract: The pheromone signal transduction in yeasts involves hormone binding to a G-protein coupled membrane receptor, interaction of Cdc24p with G.beta., and ultimately results in polarized growth towards the hormone source (mating partner), caused by changes in the cytoskeleton. The present invention describes three recessive mutants of Cdc24p, at the amino acids 189 and 190, which do not interact with G.beta., and which cause the cytoskeleton to focus adjacent to the last buding site, rather than towards the hormone gradient. In contrast to previously described Cdc24p mutants, those presented here are not affected in their normal vegetative growth and hormone-induced processes, other than cytoskeleton orientation.
