Abstract: Apparatus for thermal gated injection molding having a cavity forming insert (14) separate from the heated nozzle (10). The cavity forming insert (14) has a combination of heating and cooling extending around a central melt bore (74) leading to a gate (76). The cavity forming insert (14) has an integral electric heating element (118) with an inner portion (128) having a number of adjacent coils (132) near the gate (76). Power to the heating element (118) is switched on and off during the thermal gated cycle, and the combination of heating and cooling in the cavity forming insert (14) improves the thermal response and shortens the cycle time.

Abstract: An embroidery frame for holding a textile panel between two circular plates each having a central opening covered by the panel. The panel is held in place by being sandwiched between the plates. A compressible strip around the opening of one of the plates presses the panel firmly against the opposite panel. A clearance gap between the rims of the two plates allows the panel to extend out of the frame without creasing the panel. The circular shape of the frame permits it to be used in a standard frame holder in an automatic embroidery machine.

Abstract: A miniature infrared test target that comprises a heated four-bar test target (12) operated at a high temperature and a physically separated ambient field (20) operated at ambient temperature. A beamsplitter (28) is disposed relative to the test target and the field in a position to combine and transmit images thereof along a common axis. A lens (32) is disposed along the common axis and forms a combined image of the test target and the field at its image plane. Separation of the test and field targets permits miniaturization of the test target while maintaining a temperature difference between the field and the bars that is proportional to the true temperature difference. The target overcomes the difficulty of maintaining an extremely high temperature gradient in the target. It provides a greater contrast range than that provided by conventional miniature targets. The miniature infrared test target is made with surfaces approximating a blackbody, thereby providing immunity from the Narcissus problem and the effects of complicated environmental changes.

Abstract: A sensitive and fast low voltage lamp system controller to provide safe operation of "bare wire" systems that are particularly attractive for use in exhibition and tradeshow booth lighting. The high sensitivity is achieved by emphasising high frequency noise present during shorts and by proportionately limiting the instantaneous current that tracks the line AC voltage waveform; fast response is provided by a power FET coupled to a bridge rectifier in series with the load and both then in series with a protection relay.

Abstract: In a tape cartridge of the type used to store data on a magnetic tape in a high-speed data storage and retrieval system, the tape must be maintained at a proper tension within the cartridge so as to maintain the tape taut against the write/read head. Slackness in the tape occurs after a repeated number of changes in the tape transport direction or start/stop events, because the tension experienced by the tape is not the same in both transport directions. A method and apparatus for maintaining tape tension are disclosed wherein a selected tape characteristic is monitored, the characteristic changing as the tape tension changes. If the monitored characteristic exceeds a predetermined value, or after the passage of a selected amount of time, when the next reversal of tape transport direction occurs, the tape is moved a selected distance longer than necessary to effect the reversal so that when a desired data location on the tape reaches the location of the write/read head, the tape will again be at the proper tension.

Abstract: The present invention relates to a method for generating and correlating optical microscopic images and having wavelength-resolved measurement data of specimens from single or double scanning of individual elements of the specimen surface to be imaged using a confocal, scanning optical microscope, coupling a portion of the light from the imaging beam path into a spectrometer, and correlating the image formation with the spectroscopic data by storing the spectroscopic data in a two-dimensional region, one dimension being used to store the measured spectrum of the individual elements and the second dimension being controlled by means of the light intensity reflected from the scanned elements, or of a criterion obtained from the total information of the specimen image by means of image processing. The advantage of this invention resides in the complete utilisation of the possibilities of a confocal, scanning optical microscope and of those of the various spectroscopic methods.

IPC: H01L23/498
Filed: 1992-09-30
Abstract: Structures, and methods of fabrication thereof, are described wherein between an electrically conducting region and a ceramic region there is an interface region which has a thermal coefficient of expansion which is intermediate between the thermal coefficient of expansion of the conducting region and the ceramic region. This interface region substantially avoids separation of the adhesion of the conducting region from the ceramic region and avoids the creation of voids therebetween. The interface region is preferably a mixture of metal particles and ceramic material. The interface region is created by sintering alternately in oxidizing and reducing atmospheres which results in metal particles being disposed away from the metal body about the periphery of the metal body within the ceramic material.

Abstract: Methods and apparatuses for recording and/or reproducing data on a magnetic recording medium using helical scanning heads employ a recording format such that the words of data for a unit time period are rearranged and distributed over a pair of adjacent tracks in such a manner that those words whose position within the input or output signal is 4n th  are distributed on the first half of the first track, those words whose position is 4n+1 th  are distributed on the first half of the second track, those words whose position is 4n+2 th  are distributed on the second half of the second track and those words whose position is 4n+3 th  are distributed on the second half of the first track. In the first halves of the tracks, the general trend is for those words which occur later in the input or output sequence to be disposed closer to the centre of the track, whereas in the second halves of the tracks, the general trend is for those words which occur later in the input or output sequence to be disposed further from the centre of the track.

Title: Multiplying system
Inventor: OZAKI YASUSHI
IPC: G06F7/53
Filed: 1992-01-31
Abstract: A multiplying system based on the Booth's algorithm, comprises a Booth's decoder having a first input receiving a multiplier "Y" and a second input receiving a mode signal designating either a first multiplication of "X × Y" (where "X" is a multiplicand) or a second multiplication of "-X × Y". The Booth's decoder generates a Booth's decoded value and a sign selection signal to a partial product generation circuit which also receives the multiplicand "X", so that the partial product generation circuit generates either a first partial product of "X × Y" or a second partial product of "-X × Y" in accordance with the sign selection signal. An output of the partial product generation circuit is summed by a partial product summing circuit, and an output of the partial product summing circuit is added to a value "A" stored in an output register by an arithmetic unit. Thus, the accumulating accumulating multiplication "A = A ± X × Y" can be executed in the same hardware without using a circuit for sign-inverting the output of the partial product summing circuit.

Abstract: In a focal point network, adjacent nodes may agree to a relationship where one, a primary focal point or server node, supplies a network management service to the other, a non-focal point or served node. According to the invention, the primary focal point identifies a backup focal point node in the course of establishing the relationship. If communications between the primary node and the served node fail, the served node solicits the previously identified backup node to assume the responsibility of providing the necessary management service. If communications between the primary node and the served node are later restored, the served node will solicit the primary node to resume supplying the management service. If the primary node accepts, the served node revokes the authorization of the backup node.
