Abstract: The invention refers to a method for manufacturing a steel product having a very high hardenability in relation to its alloying content. The method is characterized by melting at least the bulk of a steel composition containing a majority of alloy ingredients to produce a steel melt; superheating said steel melt at a temperature of at least 1625°C and maintaining said melt at said temperature for at least two minutes to form a supertreated melt; prior to said superheating adding to said steel composition at least one micro-alloying ingredient selected from the group consisting of aluminum, titanium, and zirconium; teeming and casting said superheated melt to form cast products; and hot-working said cast products to form said steel product. 
     The invention also concerns a steel product in the form of a block, bar, plate, or forged shape or casting made according to the above method from a steel having the following composition in weight percent: Carbon 0.12 to 0.75, Manganese 0.3 to 1.5, Silicon from traces up to 1.0, Chromium from traces up to 5.0, Nickel from traces up to 2.0, Molybdenum 0.05 to 3.0, Vanadium 0.05 to 1.5, Niobium from traces up to 0.3, Phosphorus 0.03 max, Sulphur from traces up to 0.05, Aluminum 0.02 to 0.16 or, Titanium 0.015 to 0.08 or, Zirconium 0.015 to 0.08 or, at least two of Aluminum, Titanium and Zirconium, wherein the total amount of A1 + 2(Ti + Zr) is about 0.02 to about 0.16.

Abstract: The present invention relates to a control system for a servomechanism device such as robot, and more particularly to a position correcting control system (11-13, 15) for a servomechanism device (14) which is well suited to perform high-precision positioning or high-performance operations on the basis of a sensor (15) feedback control system such as force detection feedback control. It is characterized in that a plurality of algorithms for correcting a position target value (  x   in ) on the basis of a sensor signal (  Y   f ) are prepared and are switchedly used so as to readily switch functions, depending upon whether the purpose of a sensor control is a high-precision control or any other high-performance control, that the position target value (  X   in ) is corrected through a threshold characteristic element or a dead band element so as to make effective the correction of the position target value (  X   in ) based on the sensor signal ( y   f ), and that a correcting signal is applied through a response lag element so as to attain stabilization owing to a viscous effect bestowed on the position correcting operation based on the sensor signal (  y   f ).

Abstract: Das Spannfutter (20), insbesondere für Werkzeugmaschinen, hat einen Futterkörper (21) mit einer kegelstumpfförmigen Führungsfläche (45). Daran wird eine Anzahl Spannbacken (47) verschiebbar geführt. Die Spannbacken (47) sind untereinander durch gummielastische Federelemente (53) verbunden, durch die sie zumindest in der mittleren Spannstellung auseinandergespreizt werden. Am Futterkörper (21) ist mittig ein Koppelteil (41) axial verschiebbar geführt, das mit der Zugvorrichtung der Werkzeugmaschine lösbar verbunden ist. An seinem vorderen Ende weist das Koppelteil (41) eine kreisringförmige ebene Anlagefläche (61) auf, die rückwärts gekehrt ist. Jeder der Spannbacken (47) weist an seinem hinteren Ende eine vorwärts gekehrte Anlagefläche (62) auf, die als Abschnitt einer Kreisringfläche ausgebildet ist, die auf die kreisringförmige Anlagefläche (61) am Koppelteil (41) abgestimmt ist.

Abstract: The present invention relates to a method of forming oxide or other insulating films on semiconductor wafers and other substrates and single-crystal films (epitaxial films) having the same crystal orientation as that of the substrates according to chemical reactions between reaction gases or chemical reactions between the reaction gas and the substrates, and an apparatus therefor such as an epitaxial growth apparatus, an oxidation apparatus, or the like, and more particularly, a method of forming a uniform thin film on each of a large number of substrates and an apparatus therefor. 
     According to one aspect, vertical sets of substrates are stacked in a peripheral space radially spaced apart from a central portion of the active space by a predetermined distance. A reaction gas has passed through a reaction region on a surface of one substrate can be withdrawn outside the reactor without affecting a reaction region on a surface of another substrate. The number of substrates to be treated can be greatly increased, and at the same time uniformities of thickness, resistivity, and other qualities between substrates and within each substrate can be greatly improved. 
     When a hot wall type apparatus is employed, attachment of reaction byproducts dropping from the   inner wall surface of the reactor to the surfaces of the substrates can be prevented. Even if a plurality of substrates are arranged immediately below the reaction gas outlet port, the reaction gas can be caused to flow under a laminar flow condition, has a uniform temperature profile and can be caused to flow in the reaction region on the surface of each substrate.

Abstract: In a belt driven continually variable transmission, the drive ratio is changed by varying the radial position of the drive belt by moving displaceable sheaves (52, 78) of a pulley assembly. A system for actuating the displaceable sheaves includes a ratio control valve (320) supplied with pressurized fluid and connected to a source of ratio control pressure produced by a solenoid actuated valve (308). An orifice (330) located between the ratio control valve (320) and the hydraulic cylinder in which the displaceable sheave (52) is located has a feedback line (334) located on opposite sides of the orifice. Pressure in the feedback lines produces a differential force on the ratio control valve (320) tending to increase the flow rate to the cylinder when the pressure drop across the orifice decreases.

Abstract: A polymer laminate produced by crosshead ex­trusion suitable for wear resistant applications such as a vehicle glass run channel comprises a layer of a weather resistant rubber such as an ethylene-propylene-­diene (EPDM) rubber and a layer of a wear resistant thermoplastic such as polypropylene. The laminate is passed through an oven at an elevated temperature suffi­cient to cure the EPDM rubber, for example, at about 375°F, with ambient temperature cooling fluid being blown over the exposed surface of the polypropylene thermoplas­tic The interior polypropylene surface or interface is heated by the EPDM rubber which is at a high temperature as a result of the heat of extrusion and heat generated by cure thereof. As a result, the polypropylene interior surface or interface melts and causes it to flow and form a mechanical bond with the EPDM rubber while the exposed surface as well as a substantial portion of the polypro­pylene is kept from melting by the cooling fluid. The EPDM rubber can be extruded in the form of a channel having a longitudinal web 20 which supports and is bonded to the polypropylene wear strip 34 to form a glass run channel 10.

Abstract: A radiation image which has been recorded on a recording medium is read out at predetermined sampling intervals in order to obtain an image signal. A method for generating a radiation image signal comprises the steps of, in the course of the radiation image being read out, first applying sampling intervals corresponding to a second spatial frequency fsw higher than a first spatial frequency fss, which is the maximum of a desired spatial frequency range, along at least one direction on the recording medium in order to obtain an original image signal. The original image signal is then subjected to filtering processing in order to transmit spatial frequency components below the first spatial frequency fss, and to reduce or eliminate spatial frequency components above the first spatial frequency fss. Lastly, the original image signal which has been obtained from the filtering processing is sampled at sampling intervals corresponding to the first spatial frequency fss in order to obtain an image signal.
