Patent EP-0318814-A2 (EP)
Inventor: SATO KAZUHIKO
IPC: G01R31/3193
Filed: 1988-11-23
Abstract: Supplied with an output response signal from a circuit un­der test in each test channel, a level comparator (300) compares the signal with a reference level which defines a normal logical level, and the compared output is applied to two independent signal detectors (402, 403), wherein it is detected and held at the timing of two strobe pulses (STRB1, STRB2) which are provided thereto via two different signal lines (415, 416) at a desired time interval. These detected signals are applied to two logical comparators (401A, 401B), wherein they are compared with expected value signals, respectively. An expected value signal switching circuit may be provided by which the expected value signal in this test channel and the expected value signal in an­other test channel are selectively provided to one of the logical comparators. It is also possible to adopt an arran­gement in which test results read out of a plurality of storage areas of a failure analysis memory are provided as mask data to a desired one of the logical comparators to thereby mask its logical comparison.

Abstract: The syringe comprises means which all contribute to make it self-protecting and non-reusable. The elements of the piston (30, 60, 40) are shaped so that only one push under the action of the piston rod (50) is possible, together with the "vein test". All these elements can be separated from one another. The safeguard against reuse is reinforced by the fitting of a collar (70) at the top of the syringe body. The fitting part of the collar at the same time ensures better guiding of the displacement of the piston rod (5). The latter has a hollow conformation, and may be plugged into the nozzle (12), so that it also protects the needle from any outside contact. <IMAGE>

Abstract: In a digital clipping circuit for clipping a digital input signal according to the present invention, a comparator (12) compares the digital input signal with a reference signal, and outputs a first comparison signal when the level of the digital input signal is higher than that of the reference signal, and outputs a second comparison signal when the level of the digital input signal is lower than that of the reference signal. A selector (13) selects the reference signal when the selector (13) receives the first comparison signal, and selects the digital input signal when the selector (13) receives the second comparison signal. A compensation signal generator (15, 16) receives the first comparison signal, and outputs a compensation signal for compensat­ing the reference signal selected by the selector (13). A synthesizer (17) synthesizes the reference signal selected by the selector (13), and the compensation signal output from the compensation signal generator (15, 16), thereby to produce a compensated output signal.

Abstract: A method and apparatus wherein a conventional vacuum operated filter unit which generates a positive pressure on the particulates in a suspension against a filter membrane is converted into an anti-clogging filter unit through addition of a supplemental device which generates a counteracting negative pressure on the suspension as it is being filtered, thereby pulling the particulates in the suspension away from the filter membrane. A conventional vacuum-operated filter unit which causes the suspension to be pulled toward the filter membrane by a vacuum source and thereby creates clogging of the filter membrane with particulates from the suspension is converted into an anti-clogging filter unit by the addition of a supplemental device placed into the top chamber of the filter unit wherein the supplemental device generates a negative pressure on the filter membrane through a second vacuum source acting on the supplemental device which causes the particulates to be pulled away from the filter membrane as the suspension is filtered and permits the retentate to rest within the top chamber of filter unit while the filtrate rests within the bottom chamber of the conventional vacuum-operated filter unit.

Abstract: A chassis arrangement (13, 14) has a steerable element, in particular a wheel (11, 12), steerable on tilting of said chassis relative to the ground (38). The steerable element is mounted on the chassis (10) via first (17) and second (18) links. The first link (17) is pivotally supported at one end on said chassis and supports a substantially horizontally disposed axle for said steerable element. The second link (18) is pivotable about an axis disposed parallel or oblique to the ground and substantially intersecting the contact area where, in the straightahead position of the steerable element the latter contacts the ground (38). Means is provided between said first and second links defining a substantially vertical axis which substantially intersects the first said axis at said contact area. The steerable element is swivellable about said vertical axis (35) to effect steering on tilting of said chassis due to pivotal movement of said second link about the first said axis under the moment created by the ground pressure and its moment arm about the first said axis resulting from tilting of the chassis (10). The chassis arrangement (13) has the special feature that said means provided between said first (17) and second (18) links defining said substantially vertical axis is disposed in the centre region of said steerable element, in the region of said horizontally disposed axle (21).

Abstract: A centrifugal processing system and method introduces fluid to be processed into a centrifugation chamber, while directing the fluid away from the region of the chamber where the largest centrifugal (or "G") forces exist. The fluid is also conveyed into the force field as a generally uniform stream having reduced turbulence or being essentially free of turbulence. The system and method thereby establish, upon the entry of a high velocity fluid stream into the centrifugal field, non-turbulent and uniform flow conditions conducive to effective separation. The system and method also direct the fluid in a way the maximizes the effective surface area of the centrifugation chamber for separation. Effective separation can thereby be achieved at high inlet flow rates.
