Title: Clamping system, especially for rotating tools
IPC: B23B31/11
Filed: 1984-03-24
Abstract: A receiver body (1) carries a holder shaft as needed and has on one end face an abutment face (4), extending at right angles to the axis of rotation, and a coaxial, conical receiving bore (5). A connection part (14), which is preferably embodied as a tool carrier, likewise has on one end face an abutment face (15, 15'), extending at right angles to the axis of rotation, as well as a coaxial, conical centering stub (16) fitting into the conical receiving bore. In order to assure a high degree of concentric accuracy, even in the event of strong forces exerted laterally upon the connection part, the inner cone (6) surface of the receiving bore (15) has a cone angle that is larger by a predetermined, small difference angle (27) than the outer cone surface (17) of the centering stub (16). This difference angle is such that upon the insertion of the centering stub into the receiving bore, the outer cone comes into engagement with the inner cone surface first in the vicinity of its smallest diameter. At least one of the two cones is elastically deformable so that the two cones engage one another over essentially their entire length and face and provide for matching engagement of the abutment faces (4, 15).

Patent EP-0240247-A3 (EP)
Title: High-current operational amplifier
IPC: H03K19/0175
Filed: 1987-03-26
Abstract: An operational amplifier (10) suitable for inclusion in an integrated circuit device operating as a transceiver at a coaxial media interface to a network meeting IEEE 802.3 standards. To be included in an integrated circuit package the operational amplifier (10) must have low-power consumption and yet generate up to 80 mA of current onto the network. A design method achieves this goal, producing an operational amplifier (10) having three independently-positioned, isolated, poles. A current generator and level shifter (125) is employed with the operational amplifier which generates a current precisely proportional to a "collision" reference voltage, the current is compensated for changes in temperature and for variations in transistor gain (hFE). A very wide band level shifter matchs the current generated to the requirements of the operational amplifier so that 10% to 90% changes in current generated by the op amp can occur in 1/2 to 3/4 of a nanosecond, yet the level shifter does not consume much power. The current generator provides a single point of circuit element control for compensating for hFE variation in three transistors used within the current generator. The level shifter employs current-steering to produce the switched current which is exceptionally fast and low in asymmetry. The process used in integrated circuit manufacture permits tight control of the elements within the operational amplifier so that parameters can be held within 2% of the tolerances specified in the IEEE 802.3 standards without need of field "trimming".

Title: Thermodynamic printing method and means
IPC: G03G15/32
Filed: 1988-02-27
Abstract: In a method of printing on a printing medium (S) a variable thickness ink dot pattern representing an original image in response to an incoming digital data stream, a printing member, e.g. a cylinder (72), is formed which defines a multiplicity of discrete, independently electrically chargable capacitor microcells (94) adjacent to a printing surface of that member. Selected ones of the microcells (94) are activated in accordance with the incoming data stream so that the activated microcells are geometrically related to the dots in the pattern to be printed. Then, electrical charges are deposited on the microcells (94) selected for activation at controlled variable coulombic charge levels to create at the printing surface localized electrical fields of various strengths that are proportional to the print densities desired for the related dots in the pattern to be printed. Following this, the printing surface is contacted by a two-component, voltage sensitive, thermoplastic whereby the ink, under the influence of the fields, is deposited on the printing surface only at the locations of the microcells selected for activation, with the thickness of each ink deposit being proportional to the strength of the field at that microcell, thereby to form a variable-thickness ink pattern on the printing surface. That ink pattern is then transferred completely to the printing medium to provide a faithful hardcopy reproduction of the original image. Apparatus for practicing the method are also disclosed.
