Abstract: An adjustable electrical device, such as a trimmer capacitor, comprising a housing (14) and an electrode (30) movable relative to the housing, the electrode (30) comprising a screw- threaded portion (32) which is resiliently deformable to allow compliant threaded engagement with a complementarily screw-threaded portion of the housing (14) of slightly smaller diameter. The screw-threaded portion (32) is split to allow said deformation, the split being in the form of a slot (36) extending across the screw-threaded portion, parallel to the rotational axis of the screw-threaded portion. A further slot (34) is located at the base of the screw-threaded portion, which interconnects with the slot (36). The electrode (30) is provided with an actuating member (38) having a head portion (42) adapted to receive an adjusting tool, such as a screwdriver, and a body portion (46) which is an interference fit within the electrode.

Abstract: A method of pairing disk units in a computer system where mirroring is desirable is disclosed. Where possible, disk units are paired with other disk units located on a different bus. This provides the highest level of protection against inaccessible data due to data loss or failure of a component in the computer system. Where this is not possible, the remaining disk units are paired with disk units located on a different I/O processor, a different controller, or a different disk enclosure. Where none of these pairings are possible, the remaining disk units fall below the threshold level of protection and therefore cannot be paired within the segment. Any disk units that could not be paired are placed on a spare list. Several attempts are made to pair up disk units on the spare list. If all of these attempts fail, the paired disk units with the lowest level of protection are broken apart and added to the spare list, where attempts are again made to pair up the disk units on the spare list. After all units are paired, a pair of disk units is compared with other pairs of disk units to see if the level of protection can be increased by swapping mates. This comparison of pairs of disk units is repeated until the level of protection is optimized. Each time the computer system is started, a check is made to determine if a configuration change resulted in a lower level of protection. If so, the user is asked if he would like the disk units on the computer system to be re-paired to increase the level of protection.

Abstract: An image processor comprising a transparent plate (2) on which a document (4) is placed, and a document covering means (6) which covers the document (4) placed thereon. The document covering means (6) moves freely between a closed position at which it covers the transparent plate (2) and the document (4) placed thereon and an open position at which it permits the transparent plate (2) to be exposed. Provision is further made of a document illumination means (10) which moves relative to the document (4) placed on the transparent plate (2), and an image sensor (14) which receives the light irregularly reflected by the document (4) that is illuminated by the document illumination means (10). The image processor further has a document detecting means (8) which detects the region where the document (4) exists based on an output signal from the image sensor (14). The document covering surface (24) of the document covering means (6) has a regular reflectance of 1,5 to 40 % and gives a relative intensity of irregularly reflected light as received by the image sensor (14) of N2,5 to N8,5 in terms of lightness in the Munsell color system. The document detecting means (8) discriminates whether there exists the document (4) on the region or not in a different manner depending upon the case where the document covering means (6) is located at the closed position or the case where the document covering means (6) is located at the open position.

Abstract: A line device, preferably a line terminating device (LE) of a communication system which contains transmitting and receiving circuits (S1, S2, SN; E1) to which transmitting lines (SL1, SL2, SLN) and receiving lines (EL1) are connected, contains at least one receiving circuit (E1) comprising a circuit arrangement (KS) for compensating for crosstalk. A single circuit arrangement (KS) compensates for the crosstalk from several transmitting lines (S1, S2, SN) to one receiving line (EL1). For the compensation, a reference signal (R(1)1, R(1)2, R(1)N) of the transmitting signal is branched off from each transmitting circuit (S1, S2, SN) and a compensation signal (K1, K2, KN) is simulated by an adaptive filter (F1, F2, FN). The individual compensation signals are additively mixed with the receiving signal via subtraction inputs of a subtraction circuit (S). A part of the output signal of the subtraction signal (S) is supplied to the control signal inputs (RS1, RS2, RSN) of the adaptive filters (F1, F2, FN), the other part is processed further to become the receiving signal (DA1).

Abstract: A printed pattern is provided with a wiring pattern having a land and a through hole surrounded by the land. The wiring pattern and the through hole are read by a photoelectric image sensor to obtain a pattern image and a hole image, respectively. A pattern gauge image is defined by the pattern image, a hole gauge image having a ring-like shape is obtained from the hole image. A logical product between the inversion image of the pattern gauge image and the hole gauge signal provides a protrusion region image. An operator is applied to the protrusion image. Since the hole gauge image has an isotropic contour, the minimum annular width of the land is detected, independent of the direction in which the through hole is deviated from a land.

Abstract: A fault tolerant system has a plurality of lasers modulated by the same signal source with the signal conveyed to receivers by single mode optical fibers. The optical fiber outputs of all of the lasers are mixed in an optical coupler, the output signal or signals from which are the combined input signals from the lasers. The output single mode fibers can go to a number of receivers. By optically combining the signals in phase with each other, the failure of any laser decreases signal strength, but does not disable the system. Surprisingly, the mixing also has the capability of improving the carrier to noise and carrier to distortion ratios for the system since noise and distortion from the lasers are not correlated and are diminished by a factor of N where N is the number of lasers.
