Abstract: In a Local Area Network (LAN) comprising a plurality of stations having associated ports where each port has a unique address, an arrangement for providing selective broadcasting to a subset of the plurality of stations is disclosed. A transmitting one of the stations designates the subset by specifying two or more receiving stations. Thereafter, the transmitting station generates a single data message having a single specified address of only one member of the subset. A packet switch controller defines a mask that identifies which stations are included in the subset. The packet switch controller provides the appropriate mask to the transmitting station which then transmits a data packet comprising a data message, the specified address and the appropriate mask to the LAN. Each port decodes the transmitted specified address and the mask to determine if the transmitted message is intended for its associated station as a member of the subset.

Abstract: The rotary tabletting machine possesses a die plate (6) which is connected to a drive shaft and in which upper and lower rams (7, 8), whose position is controlled by cams (9, 10), are guided. These cams (9, 10) are provided with holders (14; 15). In machines of this type, it is only possible to exchange the die plate, for example for the purpose of cleaning individual parts when the tablet material to be pressed is changed, after a prior dismantling of the individual rams and their cam guides. This results in long shutdown times. This situation is remedied if the holders (14, 15) are connected to fixed housing parts (4) by detachable connecting means (40) and to the die plate (6) by drivers (12), to be precise in such a way that after the connecting means (40) have been detached, the die plate (6), together with the rams (7, 8) and the cams (9, 10), can be lifted from the drive shaft (1). These connecting means may consist of screws or of clamping connections. The drivers provided may be pins (12) which engage in annular grooves (19) of the die plate.

Abstract: An autotransfuser (10) that includes, in a single receptacle (15), a pair of chambers (20, 30) separated by a common wall (16). Each receptacle can alternately perform, a blood infusion or blood collection function. Each chamber includes at least three inlets/outlets, a blood inlet (24, 34), a blood outlet (25, 35) and an air inlet means (22, 32). In some embodiments of the invention the air inlet means serves alternately to couple either an air or a pressure source on the one hand or a vacuum source on the other hand to the corresponding chamber. In other embodiments of the invention, the air inlet means comprises a vacuum inlet and a separate air or pressure inlet. A disk like device (40) or valve manifold is arranged for rotatable movement adjacent the inlets/outlets. The disk like device includes four channels, one for each of air or pressure (47), vacuum (46), blood collection (48) and blood infusion (49). Each channel includes a port for coupling to external tubing and at least one channel end. The channel ends are located in the disk like device so that by rotating the disk like device to two distinct positions, one or the other of the functions can be performed by each chamber. A blood valve is also disclosed which has a float element (104) having a specific gravity which allows it to float in a pool of human blood and a significant closure force in excess of about ten to fifteen grams.

Abstract: A double-acting hydraulic piston-and-cylinder unit adapted to constitute a damper for movements in a human joint prosthesis has a boot sealingly connected to the cylinder and the piston rod to receive the hydraulic fluid under pressure as the hydraulic fluid is displaced from one or the other of two cylinder chambers upon displacement of the piston rod. The boot has a conically widening region or segment sealingly secured to the rod and adjoining the cylindrical segment of the boot surrounding the cylinder in a transition segment formed as an outwardly convex bulge and designed to ensure that initial inward movement of the piston rod will give rise to a plate membrane deformation of the elastic boot while only further displacement will result in a rolling action of the membrane. This ensures a generally cylindrical uniform configuration of the boot in all positions of the rod as is essential for effective use in a prosthesis.

Abstract: A format converting circuit for numeric data comprises an operation unit (9) which operates according to a mode decision signal to output an input data as it is or a two's complement of the input data; a storage device (11) which stores a positive or negative sign data to be read out and is reset by an initializing signal to a positive data storing state; and a control circuit (13) which operates in two conversion modes. One of the modes is a signed-to-unsigned conversion mode in which the control circuit (13) controls the operation unit (9) with the mode decision signal such that, if a sign bit of the input data is 0, the operation unit (9) outputs the data as it is while, if the sign bit is 1, the operation unit (9) outputs a two's complement of the input data. At the same time, the control circuit (13) inverts the data stored in the storage device if the above-mentioned sign bit is 1. The other mode is an unsigned-to-signed conversion mode in which the control circuit (13) controls the operation unit (9) with the mode decision signal such that, if the data stored in the storage device (11) is positive, the operation unit (9) outputs the input data as it is while, if the data stored in the storage device (11) is negative, the operation unit (9) outputs a two's complement of the input data.

Abstract: When the attachment of the video cassette to a VCR is terminated, a microcomputer drives a cylinder motor immediately to execute tape loading. In the stop state, with the tape loading completed, cylinder rotation is continued for 5 minutes without tensioning the tape and cylinder rotation is terminated after lapse of the 5 minutes. In this manner, other modes in the stop mode can be set quickly, while power consumption is also avoided. When there is no necessity of maintaining channel selection at the VCR tuner, tape loading and power turn-off may be executed after lapse of the five-minute period to further reduce the power consumption.

Abstract: A method of fabricating a high-quality tunnel oxide layer includes a two-step oxidation process. The first oxidation step includes oxidizing a substrate in an atmosphere comprising oxygen and nitrogen at a temperature of approximately 950°C, and thus is an HCl-less oxidation. The second oxidation step is performed in an atmosphere comprising HCl and argon at a temperature of approximately 1050°C. The first oxidation step is performed at a temperature in the range of temperatures for the viscous flow of the oxide to prevent any physical defects from forming in the oxide layer. The second oxidation step is performed at a temperature sufficient to passivate any mobile ions in the oxide layer in at atmosphere comprising a gettering agent, for example, HCl. By this two-step oxidation process a tunnel oxide layer which is of high quality and is not damaged during subsequent processing steps performed at temperatures at 1100°C and above.
