Title: Method for the measurement of the refractive index of a thin layer
Inventor: ISOBE TAMI
IPC: G01N21/41
Filed: 1988-10-13
Abstract: A method for the measurement of the refractive index of a thin layer, which is formed on another layer having a known refractive index, has the following steps: first, the thin layer is irradiated individually at a predetermined angle of incidence with S-polarised and P-polarised monochromatic light; then energy reflection ratios Rs and Rp are determined for the S-polarised and P-polarised monochromatic light; hereupon the light intensity of the reflected light from the thin layer is then determined and, finally, the refractive index of the thin layer is measured by means of a prescribed calculation on the basis of phase value changes of the light during its propagation from an upper surface of the thin layer to its lower layer, the phase changes corresponding to the refractive index of the medium and to the energy reflection ratios Rs and Rp being determined.

Title: Device for image scanning
Inventor: SUHRMANN ROBERT DIPL PHYS
IPC: H04N1/48
Filed: 1988-11-29
Abstract: A device for scanning coloured images with imaging optics, a monochrome semiconductor image pickup and a liquid crystal cell which is arranged in the beam path and the transmission percentage of which can be changed for the three primary colours by means of a control signal. To construct such a device as simply as possible and to achieve good colour separation, the area of light transmission of the liquid crystal cell is divided into a number of part-areas coloured in the primary colours by means of a colour filter, of which part-areas the areas with the same primary colour are in each case successively switched to transmit light. The part-images obtained for the three primary colours at the output of the semiconductor image pickup are temporarily stored and can then be supplied in parallel to a reproduction device. Such a device is particularly suitable as scanner for transparencies.   <IMAGE>

Title: Plastic-cased, light-sensitive semiconductor assembly
Inventor: SHIRAHATA HISASAHI
IPC: H01L31/02
Filed: 1988-12-06
Abstract: Plastic-cased, light-sensitive semiconductor assembly having a light-sensitive semiconductor element and a connector holder, which are contained in a casing made of a transparent plastic. An incident light surface in the form of an incident light window is formed on the casing, opposite the incident light surface of the semiconductor element. The incident light window has a smooth surface and is recessed with respect to the surface regions of the casing surrounding it, while the remaining surface regions of the casing are given a matt finish. Thanks to its recess arrangement, the incident light surface of the incident light window is protected against damage. The remaining, matt surface regions prevent the incidence of stray (scattered) light and thus ensure a reliable operating behaviour of the light-sensitive semiconductor assembly.

Patent DE-3921483-A1 (DE)
Title: Mechanical vibration damper for slow and large vibrations
Inventor: KOKULA JOACHIM
IPC: F16F7/10
Filed: 1989-06-30
Abstract: It is intended to reduce and dampen large, slow vibrations. It consists of a shell, the inner and outer contour of which describe a half ellipse, the outer contour being curved to a greater extent than the inner contour. A loose ball is located in the shell. If the device in which the vibration damper is fitted tilts, the ball rolls out of its centre position and stabilises with the shell outside its geometric centre. Its centre of gravity is thus also lower than originally. When the fluctuation falls on the other side, the entire damper has to be lifted and transported to the opposite side. Due to this and the inertia of the moving damper, the damper steadies the fluctuations. The elliptical contour can be fitted directly into the device and several shells are placed one inside the other in the case of large vibrations. In the case of vibrations in a plane, the damper is designed as a profile. Sides of the damper which are exposed to small vibrations can be of steeper design.

Title: Anticorrosion coated steel pipe welding
Inventor: SCHNEEGANS JOCHEN DIPL ING
IPC: B21C37/09
Filed: 1990-01-23
Abstract: Before welding cladded steel, treated with an anti-corrosive coating, an alloy insert is placed between the surfaces of the joint to be welded so that material of the solidified welded seam is also resistant to corrosion. To weld longitudinal seams in piping or long profiles, the insert is of a wire or strip material continuously placed between the surfaces of the joint in front of the welding zone, with or without prewarming, to be secured to one or both of the joint surfaces. The insert material contains the components of the metal corrosion-resistant cladding, where one or both carrier layers of unused corrosion-resistant steel project from one or more metal layers by the grooving to give sufficient new carrier layer joint surfaces through the grooving which can be welded without further working, or the layer materials can be folded over before welding in a continuous operation before the welding zone which moves along the seam joint.

Patent DE-4010479-A1 (DE)
Inventor: LOCHER JOHANNES ING GRAD
IPC: F23Q7/00
Filed: 1990-03-31
Abstract: Proposed is a sheathed-element glow plug (10) designed to be fitted in the combustion chamber of air compression type internal combustion engines. As with prior art devices of this kind, the glow plug contains a resistor (17) inside the sheath (13), the resistor (17) being made up of two coils (20, 21) connected in series. While the coil (20) nearest the combustion chamber is a heating coil with substantially constant resistance at all operating temperatures, the resistance-wire coil (21) remote from the combustion chamber, which acts as a control element, has a high coefficient temperature-resistance. The invention calls for the resistance coil (21) acting as the control element to consist of a cobalt/iron alloy whose structure is not destroyed when the alloy is exposed to the temperatures occurring in an internal combustion engine. According to the invention, this alloy is chosen so that it retains a face-centered cubic structure in all operating conditions of the glow plug (10). The iron content of the alloy lies between 6 and 18 % by wt., preferably 12 to 14 % by wt. The coil resistor (17) is embedded, as in prior art devices, in an electrically insulating material (18) which is a good thermal conductor.
