Abstract: The apparatus of the present invention may be utilised for the automated bonding of electronic components to a circuit board (30). A placement and bonding head (28) is attached to a manipulatable robotic arm (20) and is utilised to select an electronic component having a plurality of conductive leads from a supply of such components and position that component adjacent a plurality of contact pads on a circuit board. While retaining the electronic component within the placement and bonding head, the component is then thermally bonded to the contact pads. In one embodiment of the present invention, an electronic component may be optically inspected while being retained within the placement and bonding head. In another embodiment, thermal bonding is accomplished utilising a plurality of thermally activatable blades (52) which each include a thermocouple (56) mounted adjacent thereto. Selective low current control signals are then coupled to the placement and bonding head where transformers are utilised to amplify the current prior to coupling the control signal to individually thermally activatable blades. In yet another embodiment of the present invention, the placement and bonding head includes a plenum (76) for supplying inert gas to the bonding site so that the use of flux may be avoided.

Abstract: A method for on-line restoration of redundancy information in a redundant array storage system. The invention provides alternative methods of restoring valid data to a storage unit after a Write failure caused by a temporary storage unit fault. In the first preferred method, a valid redundancy block is generated for the corresponding data blocks on all storage units. Resubmitting the interrupted Write operation causes the old (and potentially corrupted) data block to be "subtracted" out of the re-computed redundancy block. The uncorrupted new data block is written over the old data block, and is "added" into the re-computed redundancy block to create a new, corrected redundancy block. The new, corrected redundancy block is written to the appropriate storage unit. In the second preferred method, a new redundancy block is generated from all valid data blocks and the new data block. The new redundancy block and the new data block are then written to the appropriate storage units. In both cases, the entrie method is done on-line, with insignificant interuption of normal operation of the redundant array system, and without requiring added processing during normal operation.

Abstract: The system according to the invention serves to distribute communication signals, in particular television signals, from a central station to a multiplicity of subscribers and to enable two-way transmission of telephone and data signals between the central station and the subscribers. According to the invention, the network used for this purpose is an optical waveguide network with a star-star structure in which fibre-optic amplifiers (10, 11) are provided between successive branching points. The communication signals to be distributed are transmitted via the optical waveguide network on a first wavelength ( lambda 1) to the subscribers, the subscriber-individual communication signals to be transmitted from the central station (1) to the subscribers (Ti) are converted by frequency modulation to a frequency band (FB2) which differs from that of the distribution signals (by frequency modulation) and are transmitted on the same wavelength as that of the distribution signals to the subscribers, and the subscriber-individual signals to be transmitted from the subscribers (Ti) to the central station (1) are converted by frequency modulation to a further frequency band (FB3) and transmitted optically on a second wavelength ( lambda 2) to the central station. This optical signal is amplified at suitable points (A), and a plurality of alternative embodiments for this amplification are indicated. <IMAGE>

Abstract: Depth information generating section generates depth image information representing the class of the depth of each pixel in two-dimensional image information outputted from an image input section, according to depth information outputted from an input section. A stereoscopic image information generating section generates stereoscopic image information, based on the depth image information and the two-dimensional image information. Thereafter, an image for the left eye and an image for the right eye read by an image information output section are alternately displayed on the screen of an image display section under the control of a gate. In synchronization with the change-over operation of alternately displaying the image for the left eye and the image for the right eye, the stereoscopic section controls the opening and closing of liquid crystal shutters of liquid crystal shutter glasses. A stereoscopic image information correcting section corrects stereoscopic image information in response to image drawing information transmitted from the input section. Thus, a stereoscopic image can be easily generated based on the two-dimensional image information.

Abstract: A linear image is traced on the basis of an instruction to trace the linear image through an image processing system for processing a trace of the linear image of data of an image, having an image memory (3) for storing the data of the image (15), a data memory (4) for storing data of a graphic (16), a display unit (6) for displaying the data of the image (15) and the data of the graphic (16), an input unit (5) for entering the instruction, and a semi-automatically image trace processing section (12) for processing the trace of the linear image on the basis of the instruction. The candidate of the branched direction is detected by tracing the linear image having a line width smaller than a predetermined line width; setting a point on a contour line of the linear image as a first trace base point when the trace detects a branched point at which the line width of the linear image to be traced expands temporarily; transferring the first trace base point on the contour line in a predetermined distance and setting a point existing on the contour line opposite to the contour line on which the first trace base point is located and in the position closest to the first trace base point, as a second trace base point; and detecting a middle point between the first trace base point and the second trace base point as a candidate of the branched direction.

Abstract: In the apparatus a next operating request can be accepted and reserved before the completion of the preceding operating process so that a high operating efficiency is obtained. The kind of operation request signal or operation command is discriminated, thereby discriminating at least one operation to be executed among quick response operation, writing operation, and memorized content executing operation in accordance with the operation request signal or the operation command which has been discriminated and a designated mode. An operation command corresponding to the operation request signal is generated when the quick response operation is discriminated. The operation request signal or the operation command is sequentially stored when the writing operation is discriminated. The operation request signal or the operation command which has been stored in the reserved operation memory is read out and provided when the memorized content executing operation is discriminated. In the second embodiment, at least one operation to be executed is discriminated among the quick response operation, writing operation, and memorized content executing operation in accordance with a designated mode.

Abstract: The tolerable maximum feed rate Fd is calculated in real time during operation based on the tolerable minimum moving time Ta to be determined by the data interpretation and the moving distance L of each machining block. If the command feed rate Fc exceeds the tolerable maximum feed rate Fd, the actual feed rate for the block is set to the tolerable maximum feed rate Fd, thereby realizing smooth deceleration and preventing mechanical shock of the machine tool and reduction in machining accuracy. Required time for each processing element is determined in advance, the sum of processing times corresponding each element is calculated by judging the processing mode element contained in machining for each block. Then, the feed rate is controlled by determining the tolerable minimum moving time for each block based on the calculated sum of processing times.
