Patent EP-0017722-A1 (EP)
Inventor: LEFFERTS JOHANNES
IPC: B65G15/54
Filed: 1980-02-15
Abstract: Das Siebband besteht aus einer Vielzahl von Wendein (1, 2) aus thermofixierbarem Kunststoffmonofil. Die Windungen (3. 4) durchdringen sich gegenseitig und ein Steckdraht (6) ist durch den von den Windungen (3, 4) gebildeten Kanal hindurchgeführt. Die Wendein (1, 2) besitzen keine zugfedermässige Vorspannung und das Kunststoffmonofil ist torsionsfrei. Der Steckdraht (6) hat im Siebband vorzugsweise eine gewellte Form. Das Siebband wird in der Weise hergestellt, daß die Wendeln (1, 2) derart ineinandergeschoben werden, daß die Windungen (3, 4) einer Wendel zwischen die Windungen der nächsten Wendel zu liegen kommen und die sich überlappenden Windungen (3, 4) einen Kanal bilden und ein Steckdraht (6) durch den Kanal geschoben wird. Die verwendeten Wendeln (1, 2) sind torsionsfrei und das Siebband wird nach dem Einschieben des Steckdrahtes (6) in gedehntem Zustand thermofixiert. Während der Thermofixierung kann auf das Siebband Druck ausgeübt werden. Der Steckdraht (6) erhält durch die während der Thermofixierung auf das Siebband ausgeübte Spannung und die einwirkende Temperatur eine Wellenform. Das Siebband zeichnet sich durch seine Markierungsfreiheit und seine hohe Lebensdauer aus.

Abstract: Die Erfindung betrifft ein Verfahren zum Herstellen von Halbleitervorrichtungen sehr guter Leistung, insbesondere bipolarer Transistoren mit einer stark dotierten inaktiven Basiszone und einer schwach dotierten, schmalen, aktiven Basiszone, welche durch Ionenimplantation gebildet werden. Um zu verhindern, daß die mit hoher Dosierung erfolgende Borimplantation für einen NPN-Transistor in die aktive Basiszone eindringt, wird eine selbstausrichtende, den Emitterkontakt, d.h. die aktive Basiszone bedeckende Maske für die Implantation der inaktiven Basiszone benötigt. Als selbstausrichtende Maske wird anodisch oxidiertes Aluminium vorwendet. Die mit einer alles überdeckenden Aluminiumschicht überzogene Halbleiterscheibe wird in wässrige H2SO4-Lösung in einer elektrolytischen Zelle eingetaucht, die selektiv nur diejenigen Aluminiumkontakte anodisiert, die über den durch Si3N4/SiO2 definierten Kontaktöffnungen liegen. Das durch Anodisierung hergestellte Aluminiumoxid ist porös und kann abgedichtet und verdichtet werden. Die nicht anodisierte Aluminiumschicht wird dann selektiv unter Verwendung einer chemischen Atzlösung oder durch Zerstäubungsätzen entfernt. Unter Verwendung des Aluminiumoxids über den Kontaköffnungen für die Maskierung der aktiven Basiszone wird eine hochdosierte Borimplantation durch die Si3N4/SiO2-Schichten zur Dotierung der außen liegenden Basiszone verwendet. Nach Abziehen der Aluminiumoxidschicht von der Emitterkontaktöffnung wird der Emitter mit einem gewünschten Konzentrationsprofil und einer entsprechenden Tiefe des Übergangs gebildet. Die Bildung der aktiven Basiszone wird durch eine mit niedriger Dosierung erfolgende Borimplantation in der Weise durchgeführt, daß die höchste Konzentration unterhalb des Emitters liegt. Ein Anlassen bei relativ niedriger Temperatur, z.B. 900°, wird für die volle Aktivierung des implantierten Bors verwendet und dadurch wird die Neuverteilung des Dotierungsprofils in der aktiven Basiszone kleingehalten. Die so gebildete Halbleitervorrichtung weist eine steuerbar schmale Basisbreite und ein entsprechendes Dotierungsprofil auf.

Title: Sliding guide device on machines
Inventor: KOUKAL ANTON
IPC: B23Q1/26
Filed: 1980-12-20
Abstract: A sliding guide device (130) on machines is specified in which a movable machine element (131), e.g. a machine table or a tool head, performs a feed movement in at least two directions at right angles to one another, in the course of which the feed rate can be very low at least at times. Guide elements (132) provided for the movable machine element (131), e.g. round bars whose circumferential surface is surrounded at least over one sector area by a sliding surface (167) on which the displaceably guided machine element (131) slides, are rotatably mounted and can be driven at a peripheral speed which keeps the frictional resistance between the surfaces (132, 167) sliding on one another in the range characteristic of a low value of the sliding friction. Provided as guide elements in one configuration are rotatable shafts on which the guided machine element is supported via sliding pieces. In an alternative configuration, rotationally drivable guide cylinders (132) are mounted on the machine part (131) performing the feed movement, which guide cylinders (132) are arranged so as to be displaceable in a sliding manner in guideways (137) of the static machine part (17). <IMAGE>

Abstract: Method of manufacture of planar annular friction facings for friction clutches or brakes. An annular preform of uncured friction material (13) is made by extruding a dough of uncured friction material (13) through a die (12) to form a flat ribbon whose width is substantially equal to the radial width of the facing to be formed, and the ribbon of friction material is caused on emergence from the die (12) to assume a helical form of fine pitch. The diameter of each convolution of the helix is substantially equal to the diameter of the required facing and the convolutions can be parted from the helix and flattened to produce the annular preforms.

Abstract: A control system is disclosed for a hydrostatic transmission of the type including a pump, the displacement of which is controlled by a pair of stroking cylinders (31 and 33). Communication of control fluid from the charge pump (23) to the stroking cylinders is controlled by a main control valve (47) in response to movement of a manual control lever (49). The main control valve includes a valve housing (55) which defines a pair of passages (73 and 75) through which control fluid is communicated to the stroking cylinders by means of a pair of conduits (51 and 53). A bore (83) interconnects the passages, and a valve member (89) is rotatably disposed in a bore (85) which intersects the first-mentioned bore (83).The valve member is connected to a foot pedal (107) by means of a linkage arrangement (109) such that depression of the foot pedal causes rotation of the valve member and a sufficient amount of fluid communication between the passages leading to the stroking cylinders to reduce the pressure difference between the stroking cylinders.
