Title: Method for producing customer-specific printed circuits
Inventor: SIMONE ANTONIO DR
IPC: H01L23/538
Filed: 1989-03-21
Abstract: The present invention relates to a method for producing customer-specific (application-specific) printed circuits and an electrical circuit which is produced in accordance with the method. The provision of at least two standard conductor track plane designs (1, 2), which can be used irrespective of the customer wishes, the individual conductor tracks of the two standard conductor track plane designs, at least partially overlapping in the case of conductor track planes which lie one above the other. A first conductor track plane is produced first. Subsequently, at least one individual insulation layer is deposited, that is to say a layer which conforms to the respective client's wish. This insulation layer can be deposited either in the form of an unperforated film, the definition of the circuit being carried out by positioning of the passages in the insulation layer or the passages in the film for definition of the circuit can be produced in advance, the depositing of the insulation layer onto the first layer being carried out subsequently. The passages are provided between the conductor tracks (3, 4) of the standard conductor track plane designs instead of the conductor track crossings and/or conductor track overlaps. Subsequently, a second conductor track plane is deposited by means of a screen-printing method, the passages in the insulator plane being filled with screen-printing material in order to avoid separate through-plating measures. Further insulator and [lacuna] can possibly ... Original abstract incomplete. <IMAGE>

Inventor: PARK HAN-SU
IPC: H01L21/00
Filed: 1989-05-19
Abstract: A method of contact printing a photoresist on a semiconductor in which the effective opening size of the mask can be reduced with respect to conventional masks. This is achieved using a rectangular shaped mask in which one width (W3) is larger than the resolution limit (W1) obtained with a square shaped mask such that the other width (W2) of the rectangular mask is smaller than said resolution limit (W1) to produce photoresist pattern (1) on semiconductor (2).

Title: Fibre linear density meter - which is an active pneumatic unit with rectangular measuring chamber and swing wall to reduce cross-section
Inventor: AGAPOV VALERIJ ALEXEEVIC
IPC: D01G15/46
Filed: 1989-07-13
Abstract: The active pneumatic meter assembly, to measure the linear density of fibre material, has a measuring chamber (3) with a rectangular cross section. One chamber (3) wall (5) can swing towards the opposite wall (7) on an axis (6) at the entry zone (8) of the chamber (3). An air gap (10) is between the housing (1) and the end (9) of the wall (5) towards the entry zone (8) of the chamber (3). The swing position of the wall (5) can be fixed in a number of settings. The cross seciton of the outlet (4) from the chamber (3) is altered by the positioning of the swing wall (5) on its axis (6). ADVANTAGE - The accuracy of the linear density measurement is increased through a gradual reduction of the measuring chamber cross section along its length. This gives a laminary character to the fibre material movement within the chamber to give a practically linear characteristic run for the meter.

Title: Enzymatic indicator reaction of immobilised oxidase and dehydrogenase - for substrate recycling, with immobilisation of co-factor and additional dehydrogenase for co-factor regeneration
Inventor: BUECKMANN ANDREAS DIPL ING
IPC: C12Q1/32
Filed: 1989-12-04
Abstract: Enzymatic indicator reaction uses immobilised oxidase (I) and dehydrogenase (II), in presence of NAD/NADH, with recycle of reaction prod. into starting material (enzyme substrate). The new features are that (1) the NAD/NADH is immobilised and (2) another immobilised dehydrogenase (IIa) is used for regeneration of the co-factor. Also new is an amperometric sensor for this reaction carrying (I), (II), NAD/NADH and (IIa), all in immmobilised form. (I) and (II) are immobilised on a membrane through which the aq. assay medium can flow. NAD/NADH is immobilised on a macromolecule, e.g. polyethylene glycol. USE/ADVANTAGE - Recycle of substrate amplifies the measurement signal but requires a large (stoichiometric) amt. of expensive co-factor. Incorporation of (IIa) and immobilisation of NAD allow the co-factor to be reused.

Title: Chronometer with tide indicator
Inventor: ERARD RAOUL-HENRI
IPC: G04B19/26
Filed: 1990-06-05
Abstract: The tide indicator includes a tide grid having at least one contour line of the semi-diurnal kind, in polar coordinates, and a superposed, concentric reading grid having at least one radial read-off reference mark. One of the grids is constantly entrained for movement at a constant angular speed dependent on an average tide cycle, so that the point of intersection between the contour line and the read off reference mark constantly specifies the level of the tide and the tide time which correspond to the time shown by the chronometer for a specific geographical location. The angular position of at least one of the grids can be modified by actuating a manual corrector. The tide grid respectively comprises radial reference marks specifying the different tide times, and segments of contour lines defining the different specific levels which correspond to the tide times.

Filed: 1990-08-27
Abstract: A vertically adjustable composite motor vehicle side glazing, particularly a door window glazing, is made from composite glass including two 1.5 to 3.5 mm thick thermally tempered individual glazings with a thermoplastic intermediate layer. Each individual glazing has in the marginal area tensile stresses in the core, which in the case of a glazing thickness of 2 mm amount to 54 to 76 MN/m2 and for a glazing thickness of 3 mm amount to 46.7 to 71.2 MN/m2. In the central zone within the marginal area the individual glazings have tensile stresses in the core, which in the case of a glazing thickness of 2 mm amount to 38 to 67 MN/m2, while for a glazing thickness of 3 mm amount to 33 to 60 MN/m2. Such composite glazings have high strength in the marginal area and a low strength in the central zone. Therefore they have excellent characteristics both from the static standpoint and from that of accident safety.

Title: Safety cut=off for servo driven vehicle sliding roof panel - has sensor beam positioned on edge of frame for detecting obstructions
Inventor: HEISS WERNER DIPL ING
IPC: E05F15/43
Filed: 1990-09-08
Abstract: The sliding window, or roof panel, of a vehicle is fitted with a safety device in which a sensing beam is positioned along the edge of the frame (6) to monitor obstructions when the panel is nearly closed. The drive motor is switched off when an obstruction is detected in the gap. The inhibit point of the safety cutoff is when the window opening is too small for small obstructions eg. fingers of a child. The sensing beam is activated when the window drive motor is switched on and can be pulsed rather than run continuously. The beam can be IR or ultrasonic. ADVANTAGE - Failsafe, does not require grooving of window edge to locate beam.
