Patent DE-4102856-A1 (DE)
Title: Shortening start time for optical recording-reproducing appts. esp. CD player - using higher reading speed for special information track than for remaining audio data
Inventor: BAAS DIETER
IPC: G11B19/28
Filed: 1991-01-31
Abstract: Before reproduction of data, special information is read from a particular part of a record carrier. The reading of the special information is carried out at a higher speed than the reading of the remaining data. This may be achieved by raising the frequency of the system clock. In a CD player, the lead-in track containing information about the number of tracks, and the total playing time etc. is read with the disc rotating at a higher speed than for reading the audio information. USE - For CD, video-, DRAW-, magneto=optical disc players. Esp. useful in multi-disc systems.
Patent DE-4106371-A1 (DE)
Inventor: LANGEWELLPOTT ERNST
IPC: B66F7/06
Filed: 1991-02-28
Abstract: A scissor-type lifting table comprises scissor members (16, 18), which cross one another in the respective centre area, are pivotable towards one another, support a table plate (12) and are each connected firmly, but pivotably, at one end to the floor on one hand and to the underside of the table plate on the other hand, and a drive for the mutual pivoting of the scissor members for lifting or lowering the table plate. At the other end, the scissor members bear in a displaceable manner against the floor and the underside of the table plate. The drive comprises a rotatable spindle (30) essentially running through the pivot axis (20) of the scissor members (16, 18). The spindle (30) is in each case rotatably mounted, but in an axially fixed manner, in a sleeve (32) at one end at one of the lateral scissor angles and accommodates a spindle nut (34) in the opposite end area. The sleeve (32) and the spindle nut (34) are each connected to the two scissor members (16, 18) via two guide links (36, 38; 40, 42) pivotable on either side. <IMAGE>

Title: Producing microstructure in material - by placing material on magnetically held holder opposite an electrode in vacuum, admitting reactive gas and exposing material to plasma
Inventor: YONEDA MASAHIRO
IPC: H01L21/302
Filed: 1991-10-01
Abstract: Products with microstructures are produced by placing the sample of material in a holder in a vacuum chamber and exhausting the chamber down to a specific pressure level, admitting a reactive gas to the chamber and applying a magnetic field to the sample holder or to an electrode located opposite the sample.

Title: Monitoring the shape of castings, esp. turbine blocks - using optical scanning device which feeds any deviation signals to a subsequent machining device
Inventor: BRAUKMANN HEINZ-DIETER DIPL IN
IPC: G05B19/401
Filed: 1992-07-14
Abstract: Method of determining the shape and/or the deviations in shape of finished products, esp. castings, consists of locating the product in a definite position via reception points and optically scanning the contours of the product and thereby defining any deviations from the nominal shape.

Title: Mfg. semiconductor element with differently doped layers - by wafer silicon@ bonding and wafer thinning
Inventor: GOEBEL HERBERT DR RER NAT
IPC: C30B33/00
Filed: 1992-07-30
Abstract: In the prodn. of semiconductor elements with differently doped layers, in which two or more doped silicon wafers are joined by silicon bonding, the novelty is that the thickness of at least one of the wafers is reduced by machining (esp. grinding or chemical machining) after silicon bonding and that at least one of the wafers has heavy doping.

Patent DE-4228297-A1 (DE)
Inventor: GROSE-WILDE HUBERT DIPL PHYS D
IPC: H01C10/10
Filed: 1992-08-26
Abstract: A changeable high-current resistor for use as a protective component in power switching technology has already been proposed, containing carbon as the resistor material, in which there is a boundary area with a transition region to another electrical conductor. If pressure is applied, the resistor can be kept low-ohmic in the transition region. In the present state of the art of the heat generated by the current in the resistor is transferred to the high-ohmic state. According to the invention, the pressure on the changeable high-current resistor can be suitable affected. The carbon and/or soot-containing layer (11) can be pressed by the force with a predetermined first degree of pressure on the other conductor (12, 13) to set the low-ohmic state of the resistor and, in short-circuit conditions, the pressure can be reduced within a sufficiently short time to a second degree at which the resistance in the transition region (15) increases by at least two orders of magnitude. Such high-current resistors (10) may be used in conjunction with power switches, power semiconductors, contactors and vacuum switches.
