Abstract: A direction finder is provided that can measure the incoming angles of plural incoming signals without spatially moving antenna elements and can be used in outdoor mobile communication environments. The direction finder also can shorten the measurement time. An array antenna (2) consists of plural antenna elements (1) arranged regular intervals. The received signal components due to the mutual coupling between the antenna elements are removed by multiplying time series signal groups by the inverse matrix of a coupling coefficient matrix of the array antenna. The time series signal groups are obtained by modulating signals received with the array antenna. The covariance matrix of the received signal group can be subjected to a movement averaging process (7) in terms of the Vandermonde format. The coupling coefficient matrix of the array antenna is obtained by normalizing the measurement result of an array element pattern containing a mutual coupling with a measurement result of an element pattern of a sole antenna element not containing a mutual coupling and then by expanding the normalized result in a Fourier series.

Abstract: L'augmentation de la viscosité des détergents surbasiques se produit avec le temps et en particulier à des températures élevées. On peut réduire l'augmentation de la viscosité en ajoutant des quantités supplémentaires d'un composé ayant un groupe oléophilique ainsi qu'une fonction hydroxyle secondaire. L'ajout de cet agent de réduction en quantités comprises entre 0,1 et 5,0 %, et de préférence entre 0,25 et 1,0 %, en poids entraîne une augmentation minimale de la viscosité ne dépassant pas 10 % dans les détergents stockés pendant environ 4 semaines, à des températures élevées comprises entre 37 DEG  et 82  DEG C. Le degré de la réduction de l'augmentation de la viscosité est proportionnel à la quantité d'agent de réduction ajoutée au détergent surbasique. Les agents préférés de réduction de l'augmentation de la viscosité sont des phénols alkylés tels que le dinonyl phénol, les huiles végétales telles que l'huile de colza et l'huile de jojoba, et des acides carboxyliques tels que l'acide hydroxy-12-stéarique. En outre, l'agent de réduction de l'augmentation de la viscosité est particulièrement efficace pour les sulfonates de calcium fortement surbasiques.

Abstract: The present invention relates to a chain saw comprising a chain arranged on a saw flange (5). The chain saw is usually arranged in a multi-purpose head of forestry machinery by a mounting flange (1) immobile in regard to the multi--purpose head, whereby the chain is rotated by a chain wheel (4) controlled by a power unit. In order to tighten the chain, the saw flange, or a relevant part of the chain saw comprising the same, is arranged to move parallel with the lon-gitudinal axis (A) of the saw flange in regard to the chain wheel. This is achieved by a tightening device and at least one supporting guide therein which are attached to the mounting flange of the chain saw or a structure ar-ranged therein. By arranging the supporting guide in the tightening device to extend onto both sides of the center of the chain wheel parallel with the longi-tudinal axis of the saw flange, the saw flange is made to move in a completely supported manner parallel with its longitudinal axis in regard to the chain wheel.

Abstract: The present invention entails a plant/seedling/cutting/plug growing tray and container system that includes a tray with a plurality of individual plant cells and container with each cell and container having an open top and bottom and a detachable screen bottom, and that allows plant removal either from the open bottom of the tray/container or open top of the tray/container. As plant roots emerge through an open-bottom tray or container supported above ground, the roots shrivel due to contacting dry air and temporarily suspend their growth. This bare-root growth phenomenon is known as air pruning. Proper application of root air-pruning process in conjunction with the use of properly shaped tray-cells and containers (small at the top and gradually getting larger at the bottom) significantly increases plant production, improves crop quality and promotes mechanization. Air pruning alone without the right tray and container will not provide these benefits. The present invention which utilizes computer optimization techniques to determine the proper inner sidewall angle of tray-cells and containers also allows air-pruned plants to be manually or automatically removed from the open tops of tray-cells and containers. Alternatively, in one embodiment, the plant container consists of more than one piece of sidewalls which can be put together to form a plant container. In addition, the detachable screen is provided with a series of projecting legs designed for self-supporting so as to detachably secure the screen into the plant tray and container structure to facilitate root air pruning.
