Patent EP-0360499-A2 (EP)
Inventor: HERBST GARY ALAN
IPC: H03M1/54
Filed: 1989-09-14
Abstract: Apparatus for of digitizing an input analog current signal such as a demodulated servo position error signal in a disk file includes a capacitor which is changed by with the input signal, and a plurality of comparators which compare the resulting capacitor voltage with a plurality of thresholds to produce a comparator output signal for each threshold exceeded by the capacitor voltage. The comparator output signals are sampled, and each sampling period a current corresponding to the thresholds exceeded is generated. The generated current is used to draw off charge from the capacitor until an equilibrium voltage is reached. By knowing the current generated to remove from the capacitor the voltage placed thereon by the input current signal, then the total charge applied to the capacitor can be determined. Further digital processing of the input signal value may be done without the use of a complicated digital to analog converter.

Abstract: In the manufacture of a feed block there is a base material, such as molasses, comprising an aqueous solution of carbohydrates. An insoluble phosphate-bearing material, such as rock phosphate, in particulate form is added to it. An acid, such as sulphuric acid, is added and reacts with the phosphate-bearing material. An alkali earth metal oxide or hydroxide is added to enable the mixture to set, a suitable material being magnesium oxide. The ratio of calcium to phosphorus in the block may be about two to one. The mixture may also include any one or more of the following: fatty material as a source of energy, a medicament such as an anthelmintic, and a trace element. Fibrous material, such as strawmeal, may be included to assist in holding the block together.

Abstract: A low speed decanting centrifuge (10) for separating relatively large particulate material (e.g. yeast) from a feedstock is disclosed. The centrifuge is clamped to a container (12) and the centrifuge housing (18) is pressurized to, in turn, pressurize the container and force feedstock upwardly into the lower bowl (116) of the centrifuge. A plurality of inverted frustoconical discs (278,280,282) carry supernatant downwardly and inwardly for vertical transfer to a discharge chamber (76). Particulate matter is centrifugally discharged continuously between engageable surfaces (146,148) of the lower bowl member (116) and the upper bowl member (140). The invention provides for continuous recycle as the discharged particulate matter is returned under gravity to the container (12). The centrifuge is reasonably inexpensive to produce from lightweight materials since it is not subjected to the high stresses of high speed centrifuges. Also, by operating at low speeds, under 1000 r.p.m., there will be less cell compaction and damage to the particulate material than with high speed centrifuges.

Abstract: In a device for tool changing and clamping for machine tools, in particular multi-spindle automatics, which consists of a basic holder as receptacle and a change head which can be inserted into this basic holder, is accommodated in a centred manner via plane-parallel bearing and centring cylinders and carries the tool, it is proposed to arrange a central clamping-surface support on the change head preferably in one-piece, which clamping-surface support has on either side sloping wedge surfaces which are diametrically opposite one another and extend in the transverse direction and in which clamping jaws arranged on the basic body engage on either side and thus clamp the change head in a fixed stop position. This results in large supporting surfaces and correspondingly very good directional stability and anti-rotation locking with at the same time high centring accuracy of the change head to be inserted. <IMAGE>

Abstract: In a semiconductor device having a leveling metal layer (3, 15) for forming a flat surface on an alignment mark (M2) of a level-difference, charged particles (EB) are irradiated and scanned onto a region of the alignment mark (M2), and information generated from the region of the alignment mark (M2) in accordance with a thickness of a metal in the level-difference of the alignment mark is detected. Therefore, even when the alignment mark formed by the level-difference in the semiconductor device is buried under the leveling metal layer (3, 15), the alignment mark (M2) can be detected exactly without adding excessive processes.

Abstract: The pin-socket unit comprises a pin (3) which has two approximately parallel limbs (6) which bound an oblong hole (5) formed by stamping out, are sprung onto one another and are used for pressing into an opening in a printed-circuit board. These limbs (6) merge into a shoulder (7) which is used for limiting the insertion movement. The invention aims to provide a design which is simple in design and production terms, and has a low contact resistance with extremely small insertion forces. In this design, the socket is formed by a spring socket (2) having a large number of contact springs (8). The contact springs extend, originating approximately from the region of a clamping surface shoulder (7), which defines the point of clamping of their one end, at a distance from the socket axis to the region of the front pin insertion opening (13). They are at the minimum distance from the socket axis approximately in their central region. The shoulder limiting the pin insertion movement is formed by the said clamping surface shoulder (7) of the spring socket (2).
