Patent JP-H0662502-B2 (JP)
IPC: C11B3/02
Filed: 1985-12-09
Abstract: Fatty acid alkyl esters are produced by catalytic transesterification of natural fats and oils containing free fatty acids. In a preliminary esterifying step, the free fatty acids present are reacted with a C1-C4 alkanol (e.g., methanol) in the presence of an acidic esterification catalyst, at a temperature of about 50 DEG  to 120 DEG  C. and at substantially atmospheric pressure. The resulting reaction mixture is allowed to separate into two phases: (1) an alcohol phase containing the acidic esterification catalyst and part of the water of reaction and (2) an oil phase. These phases separately recovered. The oil phase is then extracted with an immiscible extractant, preferably comprising a mixture of glycerol and methanol, to remove residual water of reaction. In the final step the extracted oil phase is transesterified with a C1-C4 alkanol, e.g. methanol, in the presence of an aklali catalyst and at substantially atmospheric pressure.

Abstract: A steering assembly (10) for use in turning steerable vehicle wheels includes a rack (12) and a pinion (14). A yoke (28) is continuously pressed against the rack (12) by a yoke spring (32). The yoke (28) has a stem (62) which extends through an opening (64) in a housing (16). During construction of the steering assembly (10), a desired range of transverse movement between the rack (112) and the pinion (14) is obtained by applying force (114) to the rack to position the rack at a first end of the range of transverse movement. The direction of the force applied to the rack (12) is then reversed and the rack and yoke (28) are moved together away from the reference position until the yoke stem (62) has moved through the desired range of transverse movement. A yoke plug (20) is then fixed against movement relative to a main housing section (18). After the rack and pinion steering assembly (10) has been constructed, it may be desired to check the range of transverse movement between the rack (12) and pinion (14). The distance between opposite ends of the range of transverse movement is determined by determining the distance through which the stem (62) on the yoke (28) moves relative to the housing (16). <IMAGE>

Abstract: The objective is to provide a data transfer control device and electronic equipment that are capable of reducing processing overheads, thus enabling high-speed data transfer within a compact hardware configuration. In a data transfer control device in accordance with IEEE 1394, a packet shaping circuit (160) shapes each packet that is transferred in from another node into a form that can be used by an upper layer, and a packet division circuit (180) writes the header of the thus-shaped packet into a header area in RAM and the data thereof into a data area. A data pointer that has been passed from the packet division circuit is appended to the header of the packet during packet shaping. Tags are used to divide packets. Information indicating broadcast information, error status information, and whether or not the packet was received during a self-ID period is appended to the trailer of the packet during the packet shaping. The information, such as ACK, that was appended to the rearmost end of the packet in a time series during packet shaping is written to the start of the header of the packet in RAM. <IMAGE>

Abstract: The transposed winding bar is short-circuited at one end and is made up of several part-conductors (1) electrically insulated from each other. These conductors are twisted according to the transposition principle. The conductors are twisted together in both end sections (4,5) and also in an active section (6). In the end sections, the conductors have a twist of between 60 and 120 degrees, preferably 90 degrees. In the active layer there is an incomplete transposition i.e. the twist in this section is uniform and less than 360 degrees. Alternatively, when there is full 360 degree transposition in the active section (6) a transposition with a void (8) is provided in the middle of this section. The twist in the active section (6) outside this untwisted region (8) then has a uniform 180 degree transposition. The untwisted section (8) preferably has a length in the order of about 10 per cent of the winding head load. When the active layer has an incomplete transposition its angular degree is preferably 10 to 15 degrees.

Abstract: The method and device are applied to a parallel computer which carries out parallel processing by transmitting and receiving messages among a plurality of processors. In a memorizing step (50), various pieces of information are memorized such as an execution starting time, standby starting time for waiting for reception of the message, message number on reception of the message, processor number of the processor, the message and time when the message is received, message number on transmitting the message and message execution ending time. In a step of obtaining the maximum delay path, a last ending processor is identified in which execution was last ended, and the standby starting time for waiting reception of the message in the last ending processor, the message number of the last ending processor, the transmitting processor number and the message transmitting processor corresponding to the transmitting processor number are all searched for among the memorized information. These searches are repeated from the last ending processor to a starting processor where execution of the parallel processing was started. Thus, the maximum delay path can be obtained, allowing recognition of where increased data transmission speed is needed. <IMAGE>

The layers (24, 26, 28) of the sensor are mounted on a substrate (20) having steps or terraces on one of its face. The steps or terraces on the substrate's surface cooperate with one or more of the ferromagnetic layers (24, 28) of the sensor to determine the layers' magnetic properties. Specifically, the thickness of one or more of the sensor's layers can be set above or below a critical thickness which determines whether the easy direction of uniaxial magnetization of a layer of that particular material is fixed or "pinned". If pinned, the layer has a high coercive field. Thus, the new device avoids a biasing layer to pin any of the magnetic layers. Preferably the easy axes of the first two ferromagnetic layers (24, 28) are set at 90 DEG  to one another in the zero applied field condition by appropriate choice of layer thickness. A method for manufacturing and several fields of use of the sensor are also disclosed.
