Title: Emulsion mask defect repair - by applying contoured UV beam of excimer laser
Inventor: HASHIMOTO HIROYUKI
IPC: B23K26/40
Filed: 1990-06-06
Abstract: Defects in the emulsion layer of a photomask are repaired by irradiation of the defect with UV light in a shape to match the defect and by destroying the defect by this treatment.  The UV beam of an excimer laser is used to pass through an aperture of suitable configuration. To correct a black spot defect (D) of the emulsion mask (7), the beam (2) of a laser oscillator (1) is expanded (3) and the UV component is reflected selectively (4) through an aperture (5x) of the plate (5) to project the shape of (5x) through a reproduction lens (6) on the mask. A lens (11) can be used to observe the spot through a semitransparent mirror (10). For the correction of white defects, a slightly adhesive resin (PVC, polyester, PU, epoxy resin) in an organic solvent is applied around the defective area. ADVANTAGE - Black hole as well as white defects can thus be eliminated without detrimental effects on the peripheral area.

Patent DE-4030823-A1 (DE)
Inventor: HUBER ANTON
IPC: B60R21/16
Filed: 1990-09-28
Abstract: A circuit configuration for a device for protecting the passengers in a motor vehicle, e.g. an air-bag system, which serves to record the collision process in a programmable read-only memory (PROM). The passenger protection system is triggered when at least two collision sensors exceed their individually set triggering thresholds. In the event of a collision the output signal of the first sensor exceeds its individually set threshold earlier than that of the other, second, sensor. The sensor of the two (S, T), referred to as the beat generator (S), sets the start of a period (Z) on exceeding the set threshold (x) of its output signal. At a time within this period (Z) at the latest, both the first and second sensors (S and T) must have exceeded its individual triggering threshold (y or w) for the passenger protection system (A) to be finally triggered. At least when both sensors (S, T) have exceeded their triggering thresholds (w, y) within this period (Z), data on the behaviour of the output signals of at least one (S) or the other (T) or both of the two sensors (S and T) are stored in the PROM (P).

Patent DE-4127753-A1 (DE)
Inventor: HARTMANN HANS
IPC: G05B19/23
Filed: 1991-08-22
Abstract: A nibbling machine (10) has a punch (33) driven by a linear hydraulic cylinder (34) and a co-ordinate carriage which moves the workpiece (12) to and fro in the mutually perpendicular X- and Y- directions. These movements can be combined. The X-carriage (88) and Z-carriage (87) each have a position-measuring system (111 or 112) which produces characteristic output pulses for changing the positions of the X-carriage (88) and the Y-carriage (87) incrementally. The output pulses are counted by an electronic control unit (79) and used to derive drive signals for a pilot valve (51) which controls the nibbling cycles of the punch (33) via a pressure-controlled main control valve (48). Consecutive nibbling cycles are triggered when the workpiece is displaced by a defined fraction of the diameter of the punch (33) relative to the latter. The feed movement of the workpiece (12) can be controlled manually. The X-carriage (88) and Y-carriage (87) can be fixed individually or jointly to the machine frame by means of electrically driven locking couplings. The simple structure of the nibbling machine (10) makes it specially suitable for use by craftsmen and, when fitted with co-ordinate carriage drives, in automated industrial mass production.
