Patent DE-4423326-A1 (DE)
Title: Back etching silicon wafer structure
Inventor: MUCHOW JOERG DIPL ING
IPC: H01L21/00
Filed: 1994-07-02
Abstract: Back etching Si wafer structure, esp. with p-, n-, p- or n-, n-, p-doped layers comprises heating the wafer structure to accelerate the etching process so that the etching medium etches the reverse side of the wafer structure. The front side of the wafer structure is protected by N2. The novelty is that the N2 is heated in a heating device (22), and the wafer structure (9) is heated to a prescribed temp. or prescribed temp. range over the course of the etching process.  The etching appts. consists of: a rotating chuck (11), on which the wafer structure (9) is clamped with the reverse side (23) facing upwards by a holding device (12); a feed (14) for the etching medium (KOH) arranged above the reverse side of the wafer structure (9); and feed channel (13) arranged below the structure (9) to N2-flush the structure. The novelty is that the holding device (12) clamps the structure (9) in such a way that the reverse side (23) is etched over its whole surface. A first heating device (22) is connected to the channel (13) to heat the N2, and a temp. regulator (25) controls or regulates the temp. of the heated N2 depending on the temp. of the structure (9).

Title: Dynamic control of motor vehicle headlamp beam-width
Inventor: KREBS THOMAS
IPC: B60Q1/08
Filed: 1994-11-05
Abstract: The dynamic control of the beam width of a car headlamp has a sensor(2) to ascertain the distance of a vehicle in front, travelling in the same or opposite directions, working on the transmitter/receiver principle. This distance is used as a control variable for adjusting the headlamp without the need for an imaging screen within a certain range of the initial adjustment. The speed and acceleration or deceleration of the vehicle in front are also determined. Further sensors measure other relevant vehicle parameters and which can be used as disturbance variables for the control signal. The unit producing this signal is linked by a serial data bus(7) to other control systems i.e. electronic accelerator pedal, braking unit and engine management (8 to 10).

Patent DE-4447488-A1 (DE)
Title: Micromechanical acceleration sensor unit manufacturing method
Inventor: MADER GERHARD DR
IPC: G01P15/135
Filed: 1994-03-30
Abstract: The method involves using a vibratable pendulum with a flexible spring which is mounted on a substrate (CH) via a holder and parallel to the substrate surface. An electrically conducting stop mounted on the substrate next to the pendulum acts as a position sensor. The substrate is first covered with a removable temporary layer (P1) to which an electrically conducting layer (P2) is applied. This is then covered with a photoresistive film (P3), whose thickness determines the thickness of the flexible spring. Photographic negative shapes of the pendulum (Gm1), stop (Gm2) and holder (Gm3) are formed by removing photoresist material up to the electrically conducting layer. The shapes are then filled with metal and the temporary layer removed at least immediately adjacent to the pendulum and stop.

Title: A ship capable of sailing in ice-filled waters
Inventor: WAGNER KNUD
IPC: B63B35/08
Filed: 1987-09-15
Abstract: In a ship (1) capable of sailing in ice-filled waters, at least one ice channel (5) is provided in the hull (2) of the ship (1), said ice channel extending substantially in the entire longitudinal direction of the hull (2) and allowing ice (22), which is broken when the ship (1) traverses an ice layer (30), to pass transversely through the hull (2) via the ice channel (5). This provides for a very great stability against rolling in the sea since the hull (2) of the ship may have a far greater width than usual and still be able to penetrate an ice layer more easily and with less consumption of energy than in the past.

Title: Plastic folder for sheets of paper
Inventor: GRAM OLE
IPC: B42F7/00
Filed: 1989-10-17
Abstract: The invention refers to a folder (1), intended for sheets (6) of a specific size. The folder (1) is made of a foil of plastic or other material. The foil is folded to form a spine (2), a front side (3) and a back side (4). A joint (10) is provided at the top edge (8) of the folder (1) to join together the front (3) and back (4) side. A corresponding joint (11) is provided at the bottom edge (9). Both joints (10, 11) are placed at a distance of preferably a little less than a sheet margin from the spine (2) of the folder (1), and at a minimum distance, in the spine direction, which is close to and preferably a little shorter than the length (17) of the retained sheets (6). If the distance is shorter, then the joined areas (10, 11) at the top (8) and bottom (9) will press downwards and upwards respectively against the top and bottom edges of the sheets (6), by which arrangement a sufficient retention of the sheets (6) is achieved. Insertion and removal of sheets (6) can be quick and easy and they can be turned over like leaves in a book.
