Patent DE-4112724-A1 (DE)
Title: Cutting continuous magnetic tape - using pair of rotary blades above and below tape, which are offset slightly to avoid burred edge
Inventor: SAKAI NAOKI
IPC: G11B5/84
Filed: 1991-04-18
Abstract: Cutting continuous magnetic tape, having a magnetic coating on a nonmagnetic substrate, is carried out from the front and back of the tape with a pair of rotary blades. The axis of rotation of the blades is parallel to the surface of the tape and in the direction of the tape width and the blades have a radial overlap. The novelty is that the gap between the cutting edges of the blades in the tape width direction is 3-20% of the thickness of the tape. Pref. at least one of the blades has a bevelled cutting edge. The bevel pref. is such that the bevel height along the tape thickness direction at the surface is 1.4 to 100 times the tape thickness and the bevel width along the tape width direction at the side is 1/40 to 18 times the tape thickness. ADVANTAGE - The technique avoids forming burrs along the edge of the tape and soiling the tape running system or peripheral equipment used in the tape mfg. process.

Title: Water cleaning - has catch basin for overflow of water and air mixt. for sepn. by gravity into pptd. and floating portions
Inventor: HENNINGER-GEIER WALTRAUD
IPC: E03F5/16
Filed: 1991-05-24
Abstract: To clean waste water, especially when contaminated by grease and oil, the soiled water flow is mixed with an air stream to pass into an overflow basin (12) and flow over the edge. The overflow (54) is caught in a basin (16) where it separates under gravity into a pptd. portion (56) and a floating portion (58). They are extracted separately. The air released at the overflow is led off through an exhaust channel (76). Pref. the floating portion (58) in the catch basin (16) passes over an overflow to be caught in a following collection vessel (20). The mixt. of soiled water and air is cooled in the overflow basin, using cold water which is thereby heated by heat exchange for use in another process. The pptd. (56) and/or floating (58) portions can pass from the overflow basin (16) into further basins to be sepd. further into precipitated and floating portions, or they are passed to a further overflow basin(s) charged with air to flow into catch basins for sepn. into pptd. and floating portions. A basic powder reagent, e.g. CaO is sucked into the solid water for mixing, through the air stream. ADVANTAGE - The method gives an outflow of clear water, without a build-up of fat and grease or other waste particles.

Inventor: MUELLER HEINZ KONRAD PROF DR I
IPC: F16J15/34
Filed: 1992-03-24
Abstract: In order to return the fluid which has penetrated into the sealing gap of a floating ring seal, recesses with closed edges are machined inside the region permanently covered by the sealing surfaces in a sealing ring in which the fluid is drawn to an end of the recess very close to the chamber to be sealed and hydrodynamically taken to a high pressure. Mirror-image recesses are effective regardless of the direction of rotation. The recesses are machined in very small sliding surfaces of ceramic sealing rings using a laser beam. Such a floating ring seal has a relatively low leakage rate with low friction. Two fluids can be mutually sealed with a double recess array.

Title: Passivation of semiconductor wafers to minimise stress and thin film cracking - using 1st layer which after planarisation encloses the metallisation pattern and further layers to provide specific protection
Inventor: TUTTLE MARK E
IPC: H01L23/00
Filed: 1992-08-27
Abstract: In the process, as a last step the wafers have the definition of a pattern in the upper metalisation layer (64). Then, an insulating dielectric layer (66), pref. undoped Si02, is metal stripe. This layer is then planarised, pref. using a chemical or mechanical polishing process, until a suitable thickness remains which encloses the metal pattern. A planar layer (70) is then deposited on top of a material which gives adequate mechanical, chemical and humidity protection pref. Si3N4 deposited by plasma enhanced CVD using SiH4 and NH3. Also claimed is the planarisation using photoresist in an etchback process or a reflow process. USE/ADVANTAGE - The process avoids the formation of a profile of the passivation layer which can lead to thin film cracking. It also ensures that an even coating of the metallisation layer occurs which improves the resistance to moisture ingress.
