Granted: 1990-04-16
Abstract: Selected areas of a web workpiece (39) are plated in the appts. (11) where workpiece and anode are, in close proximity, separated by a brush belt (35) in contact with the workpiece.  The belt is of open cell foam, backed with a continuous loop of structurally stable material such as Titanium, with openings for plating soln. to pass through.  It picks up soln. from openings in a box manifold header, continually replenished as it passes over an anode, and brushes it onto the required area of the cathodic workpiece.  The workpiece is guided to contact the belt over a range of pressures and angles.

Title: Battery - powered device
Inventor: SCHMIDT ROBERT H MUNNING
IPC: G01R31/36

Granted: 1997-07-05
Abstract: If in the case of a load (R1) powered by a battery (6) the detection means (10) detect a battery voltage below a first threshold value (V1) defined by an adjustable voltage source (20), first time-measurement means (40, 50) measure the time interval during which the load (R1) is powered by the battery (6), at a voltage below this threshold value (V1). If subsequently the load (R1) is switched off and not connected to the mains voltage via a power-supply circuit (1), the battery (6) is discharged by a discharger (30). Second time-measurement means (40, 60) measure the time interval during which the discharger (30) is operative until the detection means (10) detect a battery voltage below a second threshold value (V2), which is defined by a voltage source (25) and at which the battery (6) may be regarded as fully discharged drained. After comparison of the sum of the time intervals measured by the first and the second time-measurement means with the reference value, correction means (70) correct the first threshold value (V1) in such a way that during a next discharge the time measured is better in agreement with the reference value.

Title: Zn-sn alloy plating steel sheet with an excellant corrosion resistance, adhesion and workability and process therefor
Inventor: JONG JAE-IN
IPC: C23C16/00
Filed: 1991-11-07
Granted: 1994-01-05
Abstract: The steel sheet having excellent corrosion resistance, adhesion property and workability includes a Zn-Sn alloy vacuum deposited layer of 10-70 g/m2 composed of 10-70 wt.% Zn and 30-90 wt.% Sn. The method for vacuum deposition comprises; (a) placing Zn and Sn vaporising sources charged with respective Zn and Sn in a vacuum chamber; (b) evacuating the vacuum chamber to below 10-5 torr; (c) blowing Ar gas in the vacuum chamber; (d) cleaning a substrate by supplying a negative voltage of 500-1000 V; (e) heating the substrate at room temp. to 250 deg.C; (f) degassing the vaporising sources by introducing a current; (f) vacuum depositing Zn-Sn alloy by opening the covered shutters of the Zn and Sn vaporising sources.

Title: Metal wiring method of semiconductor device
Inventor: SHIN HONG-JAE
IPC: H01L21/28
Filed: 1991-12-18
Granted: 1994-12-23
Abstract: The method includes the steps of forming an insulating layer (2) to be thinner than a half of the metallic wiring film width (W) in thickness on the lower layer (1), patterning the layer (2) to form a metallic wiring pattern, forming a metallic layer (3) to pattern the metallic layer (3), until the patterned film (2') is exposed, to form a metallic wiring film (3'), and forming a second insulating film (4). The method improves the insulating characteristic and planarization.
