Patent EP-0306609-A3 (EP)
IPC: C21D8/00
Filed: 1988-04-22
Abstract: Die Erfindung betrifft ein Verfahren zur Herstellung eines 
Halbzeugs oder Endprodukts aus einphasigem, hcohlegiertem marten­
sitischem Chromstahl durch Warm- und/oder Kaltverformung. 
Häufig treten bereits bei der Verarbeitung von hochlegierten mar­
tensitischen Stählen Rißbildungen durch Sprödbrucherscheinungen 
auf, die die weitere Verarbeitung in Frage stellen oder sogar völ­
lig unmöglich machen. Solche Schäden können sich in manchen Fällen 
in hochbeanspruchten Anlagenteilen erst während der Beanspruchung 
bemerkbar machen und zu unvorhersehbaren Ausfällen führen.  
     Eine Untersuchung ergab, daß das Auftreten dieser Schäden nicht 
von der chemischen Zusammensetzung des Stahls, sondern von der 
Art der Bearbeitung abhängt und daß für diese Schäden der Gefüge­
bestandteil δ-Ferrit verantwortlich ist, der sich häufig während 
der Verarbeitung des Stahls bildet.  
     Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung von 
Halbzeugen und Endprodukten zu schaffen, das die Bildung von δ-­
Ferrit während der Stahlbearbeitung ausschließt bzw. durch das das 
evtl. während der Stahlbearbeitung gebildete δ-Ferrit wieder auf­
gelöst wird.  
     Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß 
   a) nach Kaltverformung mit einem Kaltverformungsgrad von mehr als 
etwa 20 %    b) nach Abschluß des Verformungsprozesses durch Warm- und /oder 
Kaltverformung    
zur Erzielung eines δ-ferritfreien Gefüges vor der Vergütungs­
wärmebehandlung eine zusätzliche, als Stabilisierungsglühung be­
zeichnete Wärmebehandlung durchgeführt wird.

Title: Head supporting structure in disk drive system for double sided flexible disk
IPC: G11B17/32
Filed: 1988-07-20
Abstract: A mechanism for supporting a pair of magnetic core 
heads (1, 1') for reading and writing magnetic codes on a flexible 
disk (10) having magnetic coatings thereon while the disk is 
rotating. Each of the heads (1, 1') is disposed on either side of 
the disk. The head supporting structure (3, 3') allows one of the 
heads to rock about a radial axis with respect to the disk, 
i.e., pitching, and to rock about a circumferential axis 
with respect to the disk, i.e., rolling, as well as to move 
in the direction normal to the disk face. On the other 
hand, the other head is allowed to pitch and move normally 
to the disk face but prevented from rolling. Thus, it is 
possible to minimize the radial dislocation of the head core 
with respect to the recording tracks, while effectively 
ensuring follow up characteristics of the head.

IPC: F16D37/02
Filed: 1989-08-17
Abstract: An electrorheological fluid torque transmission and 
conversion system provides for variable control of torque in 
clutch and brake applications. Communication of mechanical 
energy between the drive elements (30,18) is accomplished 
by magnetic coupling to eliminate the need for a dynamic 
fluid seal for interface of moving parts to the interior 
portion of the electrorheological fluid containment chamber 
(16). Permanent magnets (44,46) are associated respectively 
with each of a first member (36) and a second member (38) 
which are magnetically coupled through a surface (34) with 
low magnetic permeability such that the first member (36) 
and second members rotate (38) in unison. A variety of 
permanent arrangemnets may be utilized. Further, the drive 
element (42) internal to the electrorheological fluid 
chamber (16) may be both mechanically and electrically 
decoupled. A floating electrode may be capacitively coupled 
through the fluid to the power supply. 
Inner and outer conductive plates (56,58) are provided for 
increased fluid surface contact area. Spacing between the 
inner and outer plates (56,58) is determined by the thick­
ness of inner and outer ring members (60,62) therebetween, 
which may be easily removed and replaced for simplified 
assembly and adjustment. Condition responsive control of 
the electrorheological fluid torque transmission and 
conversion system is provided by closed-loop feedback of a 
 
 
signal indicative of rotational speed between the drive 
elements to the control system. The control system (12) 
may also incorporate internal power generation (80) to 
provide a self-contained system which does not require an 
external power source.
