Title: Silicon nitride anti-reflection film prodn. for use in photolithographic steps of semiconductor device mfr. - by selecting optical characteristic of film, by determining values of real and imaginary parts of specified relationship
Inventor: TSUJITA KOUICHIROU
IPC: G03F7/09
Filed: 1993-04-08
Abstract: In anti-reflection film prodn., a complex refractive index is selected as the optical characteristic of the film, which is used in photolithography in semiconductor device mfr. Selection process involves determining values of the real part (n) and the imaginery part (k) of the relationship n-i.k (i=imaginery unit) in the ranges n=1.0-3.0 exclusive and k=0.4-1.3 exclusive, the relationship being indicative of the complex refractive index when the light used in photolithography has a wavelength in the range between an i-line (365 nm) up to KrF light (248 nm). ADVANTAGE - An anti-reflection film, having optimal optical characteristics, can be produced simply without the need for experimental measurement of refractive index.

Title: Method for a device for determining the weight of loads coupled to a tractor and device for carrying out the method
Inventor: HESSE HORST DIPL ING DR
IPC: B60P5/00
Filed: 1993-08-21
Abstract: A method for a device for determining the weight of loads coupled to a tractor is proposed, which device is coupled to the tractor in a vertically adjustable way with the aid of a hydraulically actuable linkage of an electrohydraulic control device for a lifting mechanism, it being possible to derive the weight by means of the signals of a load-dependent pressure sensor. In order to minimise the influence of inclinations about the transverse axis of the tractor in determination of the weight of the coupled loads, the coupling points of the upper and lower links are adjusted in such a way that they reach their parallel position, serving as measurement position, when the upper link and lower link lie parallel to the surface (27) of the ground, the longitudinal inclination of the tractor then exerting the minimum influence on the hydraulic pressure, and thus the weighing result. <IMAGE>

Patent DE-4407727-A1 (DE)
Title: Lock=up clutch for torque converter
Inventor: ROWE GERALD
IPC: F16H45/02
Filed: 1994-03-08
Abstract: The torque converter includes a movable piston plate (6) which presses a friction clutch lining (7) onto the housing of the torque converter to bridge the action of the torque converter. The lining is wedge shaped, with the thinner end towards the shaft. At small torques only the outer edge of the friction lining contacts the clutch housing. As the torque increases so the piston is deformed and an increasing area of clutch lining is contacted until a maximum torque the lining is pressed flat onto the housing. The lining can also be fitted to the piston surface via an elastomer pad and with an intermediate layer between the lining and the pad. The layers are vulcanised together. To reduce vibrations the lining can have a non circular shape.

Title: Method and apparatus for increasing the efficiency of a waste-heat boiler
Inventor: LILJA LAUNO
IPC: F22B1/18
Filed: 1994-03-30
Abstract: The invention relates to a waste-heat boiler, which is arranged downstream of a suspension melting furnace, in particular a reverberatory melting furnace. In a boiler of this type, the dust-carrying gases produced in the suspension melting furnace are prevented from flowing directly from the radiation area of the waste-heat boiler into the convection area in order to reduce the tendency to form dust deposits which are caused by these gases and in order to utilise in an advantageous manner the entire volume of the waste-heat boiler and at the same time increase the dwell time of the gases. The invention likewise relates to a method of intensifying the mixing of the gases and of increasing the total dwell time in the radiation section of the waste-heat boiler. <IMAGE>

Title: Angle grinder
Inventor: KUMMER MARTIN
IPC: B24B23/02
Filed: 1987-09-08
Abstract: Angle grinder comprising a disk-type toothed wheel (11), driven by a gear system, on a grinding shaft (12), at the end of which is supported a clamping device (13) with axially adjacent grinding disk flanges (14, 15), between which a grinding disk (16) can be clamped axially.
