Title: Precision alignment procedure for VLSI process - using sensor to detect image of illuminated adjustment mark carried by adjusted object
Inventor: TATSUNO KYOICHI
IPC: G03F9/00
Filed: 1991-01-22
Abstract: The alignment method uses adjustment marks carried by the adjusted object, for bringing it into a defined reference position. A memory sensor receives an image of the adjustment mark during illumination of the part of the object carrying the latter. The mean position of the image relative to the sensor is used to calculate the spacing from the reference position for corresp. adjustment of the object. Pref. the adjustment of the object is effected within orthogonal reference coordinates. USE - Adjusting chip carrier relative to projection lens in VLSI process.

Title: Fibre-bound material comprising hollow fibres embedded in matrix - has fibres closed, gas tight at ends and filled with air-hardened resin or with resin to which hardening agent is added
Inventor: ZIMMERMANN WERNER DIPL PHYS
IPC: C08J5/04
Filed: 1991-03-09
Abstract: The hollow fibre has a cover which is sealed at the ends, and filled with air-hardening resin and drive gas, partic. air. The resin and the drive gas can be sepd. regularly inside the fibre or irregularly so. In the union of fibres, a large number of fibres are used bound together by a matrix, and instead of using a resin hardenable by air, the fibres can be filled with a resin to which a hardening agent has to be added. In this event, it is necessary for the hardener either alternately to be filled with the resin and with the drive gas, or for particular fibres to be filled with resin and hardener next to the driven gas. ADVANTAGE - As a fibre-bound material.

Inventor: BLEICH KARL-HEINZ DR ING
IPC: G01N29/07
Filed: 1991-09-18
Abstract: A process for optimizing soldering allows bondings (USB, TSB, TCB, SPTAB or others, including macro-solderings) to be obtained having a high and constant quality. According to this process, the ultrasonic vibration curve during soldering is recorded and evaluated. The results from the evaluation are used to control the soldering parameters so as to optimize them and to control the quality of the bonds. The number of troughs and peaks of the mechanical amplitude curve envelope during soldering, as well as their spacing in time, are used for the optimizing control. A process control quantity for individually dosing the process energy required for each bonding is derived from unsteady conditions of vibration after dosed acoustic energy jumps. The harmonic content of the ultrasonic vibrations at the bonding tool is used for non-destructively controlling the quality of each bonding site.

IPC: B31B50/86
Filed: 1991-10-31
Abstract: The invention concerns a process for making a sack or bag with a flat base when filled and with a handle and a sack or bag made by said process. The aim is to simplify known processes. To this end, three parallel previously grooved folding lines (3, 4, 5) are made at one end of a piece of flexible tube (1) with side folds (2), perpendicular to the side edges. The base is then pulled out and a rectangular covering sheet (8) with glued edges is pasted in and a part is folded to form a flap (10). The folded edge of the flap (10) lies approximately on one of the two folding lines (5). The region (11) of the base above one of the two upper folded edges (5) and the flap (10) is then glued over an area corresponding to the opposite part of the base, to which the flap is then bonded. The handle hole is then stamped out of the glued region between the folded edge and the outer end. After the sack or bag is filled, the open end is closed in a conventional manner.

Title: Printing pattern - is formed by projecting an image on an ink layer on a base which hardens in light of a given wavelength
Inventor: VIDONI WERNER
IPC: G03F7/20
Filed: 1992-04-01
Abstract: To produce a pattern for screen or photogravure printing, a printing ink is applied to a base (1), which hardens through inlet at a given wavelength. A photopositive (7) is transferred by light of a given wavelength to apply the printing pattern (8) to at least one section of the ink layer (5). The unlit section of the layer (5) is removed by a pad or the like. Also claimed is a screen (11) of the same ink as the print. Pref. the photopositive is projected to the printing ink or applied by contact paper transfer. The ink is applied in a thickness, accoridng to the depth of the base body (1), by an ink pot with a scraper edge, spraying or spreading. The ink thickness is 5-50 micrometer and esp. 25 micrometer. Ultra-violet light is pref. for the projection or contact paper transfer directly, using a film or indirectly through a epidascope. The hardening is by a computer-controlled laser with a set wavelength, esp. a UV laser. The removed and non-illuminated section of the screen (11) is applied to the material by an ink carrier for printing. After the unlit section has been removed, the hardened ink layer adhering to the base (1) forming the pattern, is removed by a scraper. The depth of the base plate is raised to the plate surface level, to be removed by a scraper. USE/ADVANTAGE - The pattern can be transferred to the screen or plate easily and rapidly, at low cost, for multiple use and suitable for short runs.

Patent DE-4221662-A1 (DE)
Inventor: KOEGEL WALTER
IPC: B60K25/06
Filed: 1992-07-02
Abstract: It is known to attach driven implements to the front of a utility vehicle which are, however, rigidly secured (e.g. front-mounted pumps on fire engines). On account of the rigid mounting arrangement, the front grille can only be partly opened, if at all, or must be cut out or removed for maintenance purposes. Moreover, the driver's compartment can only tilt through a small angle on account of the front-mounted implement, so that it becomes more difficult to reach the engine to carry out maintenance work. An arrangement of an attachment implement at the front of a utility vehicle, in particular with a tiltable driver's compartment (4), is proposed, the attachment implement (2) comprising a pivot mounting (7) which enables the implement to be pivoted downwards into a position (B) in which it is not used so as to make the front of the utility vehicle more accessible for maintenance work, for example, and/or increase the angle of tilt of a driver's compartment. <IMAGE>

Title: Inherently safe reactivity control mechanism for nuclear reactors - dependent upon maintenance of 0.5 - 1 percent of the reactivity producing fuel suspended in a diverted part of the main coolant flow
Inventor: SINGH JASBIR
IPC: G21C9/02
Filed: 1992-09-01
Abstract: A means for the independent self-stabilising control of the reactivity of a neutron chain reaction within a nuclear reactor. Part of the neutron producing fuel that sustains the chain reaction is suspended within the active part of the core by a diverted part of the main coolant flow. The fuel comprises coated granules which are held up by the fluid flow against the force of gravity. Should the main coolant flow off the subsidiary flow also shuts off and the fuel granules fall out of the active region of the core. The reactivity of the fuel granule amounts to 0.5 to 1% of the total core reactivity. USE/ADVANTAGE - The process of suspending fuel granules is meant as an alternative to emergency shut down rods and is to shut off the reactor in emergency situations. The process is inherently safe. It is not dependent on the operation of control and on shut down rods.
