Abstract: A substrate (30) for attaching electrical devices (42) having an interconnect wiring structure (34) and a support (32) for the interconnect, the support having a number of vias (38), or throughholes, extending therethrough and electrically connected to the interconnect. The substrate allows for attachment of the electrical devices on the side of the support opposite the interconnect at the vias, rather than on the interconnect itself. By so doing, the chips can be packed more densely since the area between the chips normally reserved for engineering change pads, test pads and the like is not required, these functions being performed on the interconnect on the opposite side of the substrate.

Abstract: The sliding nut (16) or sliding bolt is intended for insertion in C-rails (10) having edge webs (14) pointing inwards. In the assembled state, the edge webs (14) engage in longitudinal slots (22) in the nut (16) or in the bolt head. In a manner known per se, the longitudinal slots (22) are provided with projections which release deformations of the edge webs (14) when the nut or bolt is clamped against the C-rails. However, the special feature is that at least one projection is formed by lateral curving or such obtuse- or acute-angled deflection of the side wall of a longitudinal slot (22) that it bends an edge web (14) laterally in the form of an arc.

Abstract: A measurement of standard light is performed during radiation measurement for correction and offset correction of radiation measurement apparatus. The standard light emitted by LEDs (12-1 ∼ 12-n) falls on PMT (10-1 ∼ 10-n). An output signals of preamplifiers (15-1 ∼ 15-n) corresponding to the PMT (10-1 ∼ 10-n) are entered into a system controller (26) after being subjected to predetermined analog signal processing. The system controller (26) calculates a gain correction value and an offset correction value on the basis of initial correction values and output values of the preamplifiers (15-1 ∼ 15-n), whereby gain control and offset control can be performed stably even in radiation measurement.

Abstract: The invention relates to a table with a table frame and a tabletop, which is settable in both height and inclination by a control device. Varying the height and inclination of the tabletop with a simple control device and a support frame is accomplished by providing that the control device has two support devices. The two support devices are pivotally attached to the support frame in the upper region of the middle cross member of the support frame about transversely extending pivot shafts. The support devices on the underside of the tabletop are supported on the tabletop about transversely extending pivot shafts, but are guided adjustably within the depth of the tabletop. The control device selectively raises the support devices individually or in common upward in the direction of the tabletop or lowers them individually or in common downward in the direction of the support frame, in the course of which platform-shaped pivot shafts of the support devices move toward or away from one another.

Abstract: A VLSI compatible, random number generator being highly invulnerable to cryptographic attack is based upon a low frequency sampling of the output of a pseudo-random number generator which is operated at a varying frequency from a free-running ring oscillator. In a first embodiment, a free-running ring oscillator is used to drive a sampled linear feedback shift register. Because of the variations in power supply voltage and other circuit parameters over time, the frequency produced by the ring oscillator, when applied as the clocking input to the linear feedback shift register, causes the linear feedback shift register to operate in an aperiodic manner. The asynchronous, serial pseudo-random number output from the linear feedback shift register is sampled period­ically, thereby introducing randomly occurring de­viations from the pseudo-random number sequence. In a second embodiment of the invention, a variation of the free-running ring oscillator is employed as the pseudo-random number generator, by introducing into the feedback loop of the ring oscillator, an exclusive OR circuit which is connected so that the ring oscil­lator thereby produces a serial, pseudo-random number sequence. Additional uncertainty in the sequence of random numbers produced by the free-running pseudo­random number generator, is caused by the race con­dition which occurs at the inputs to the exclusive OR connected in the circuit. This can cause unpredictable skipping from a first portion of the pseudo-random number sequence to a second portion of the sequence when unbalanced signal delays occur due to variations in power supply voltage.

Abstract: Magnetic tape cassette apparatus (1) with a head plate (10) and a magnetic head (13) arranged on the head plate (10) and having a cylindrical tape-contact face (12) and an air gap (25). The magnetic head (13) belongs to a head unit with a head mount (16), which has a tape guide (18) in each case ahead of and behind the magnetic head (13) in the direction of tape transport, with cylindrically curved guiding faces (21) as well as aligning faces (23), bounding the latter on one side, on one of their axial ends in each case. Each of the guiding faces (21) is adjoined by a controlling edge (24) which, on account of its inclination with respect to the guiding face (21), keeps the magnetic tape (11) pressed with one tape edge against the respective aligning face (23) during tape transport, the axial length of the guiding face (21) being less than or equal to the tape width (b). At a distance from the guiding face (21), each controlling edge (24) of the head mount (16) goes over into a deviation-limiter face (26), the distance between the opposite aligning faces (23) and deviation-limiter faces (26) being constantly greater than the tape width (b) from the transitional point (27) onwards, in such a way that, when the magnetic tape (11') lifts off the guiding faces (21) while still remaining in contact with the tape-contact face (12) of the head (13), the position of the magnetic tape (11') is limited with play in the direction of its width (22), and the said distance increasing from the middle of the respective deviation-limiter face (2) to its side edges (26a, 26b).

Abstract: A sheet tension measuring device is disclosed for measuring the tension of a moving sheet (20) wherein a moving sheet is accurately positioned with pinchers (52, 54) at 2 spaced locations. The sheet is deflected between these pinchers from its nominal straight line path, and the amount of deflection and deflecting force are measured (100, 84). The pinchers iron out any wrinkles in the sheet as the moving sheet slides through the pinchers. Sheet tension is computed based upon the measured deflection force and deflection distance. The resulting measurements of local sheet tension are used to correct nondestructive sheet strength measurements. A device and method are also disclosed for nondestructively determining the sheet strength and the extensional stiffness of the sheet in the machine direction and in the cross-direction.
