Title: Identification of individual wires in cable harness - using hand-held scanner to read bar=code pattern of wire insulation for interpretation by computer followed by identification display
Inventor: KNUEPPEL VOLKER
IPC: H05K13/06
Filed: 1992-06-10
Abstract: The harness (8) has a number of individual wires (1-7) that can be of small diameter and are difficult to identify with the naked eye. The insulation at the end of each wire carries a bar code (9-15). In order that each wire is connected to the appropriate terminal in a multiway connection the bar code is read by a hand-held scanner (16) with an opto-electrical sensing head (24). The sensor output is fed into a computer which displays the identification number. An alternative type of reader may be used. ADVANTAGE - Easier identification of wires, since no small signs or numbers have to be discerned.

Title: Suction motor control for vacuum cleaner - has dust detector in suction opening giving electrical signals corresp. to amt. of sucked dust
Inventor: BAEG SEUNG MYUN
IPC: G01F1/74
Filed: 1992-06-24
Abstract: A wave-form distortion correction unit (20) converts the output signals from the dust detection unit (10) into wave-form distortion-corrected pulse signals related to the amount of dust. A speed control unit (30) computes a speed control value in relation to the actual amount of dust according to a working cycle of the pulses given by the correction unit (20) over a predetermined time. The correction unit has a differentiator (21) for receiving the output signals from the dust detection unit and a comparator (22) comparing the output signals from the differentiator with a previously established reference value to derive the wave-form distortion corrected pulse signal. ADVANTAGE - Size and amount of dust is established more accurately than in control systems of conventional vacuum cleaners and speed of suction motor corresponds to size and amount of sucked-in dust.

Title: Hyperfine structure mfr. to increase capacitor area in IC - by anisotropic etching of a doped poly:silicon layer or matrix layer using a deposited poly:silicon@ layer consisting of isolated hemispheres as masking aid
Inventor: JUN YOUNG KWON
IPC: H01L21/3065
Filed: 1992-07-09
Abstract: Prepn. comprises on the layer (2) to be etched another layer (3), with a lower or the same etch rate, is deposited in the form of adjacent hemispheres. The deposition time is controlled to give a required distance between tops and valleys in the layer. The layer may be etched down partially after deposition to adjust these distances. A 2nd. layer (4), with an even lower etch rate, is deposited to planarise the surface. The top layer (4) is etched down until the tops of the hemispheres in the 1st. masking layer (3) show. Then, using the top layer (4) as masks the 1st. layer (2) and the intermediate layer (3) are etched down. Also claimed is the process in which the 3rd. layer (4) is not used, and the masking action is provided by the layer (3) which has a lower etch rate than the 1st. layer (2). USE/ADVANTAGE - The structures give a large increase of active capacitor area, resulting in an increase in capacitance value. The process does not require a photo lithographic process, and results in structures with a cross-section dimension of 0.1 micron.  The process is used in the mfr. of DRAMs.

Patent DE-4313504-A1 (DE)
Title: Explosive-actuated driving tool
Inventor: JOCHUM PETER
IPC: B25C1/10
Filed: 1993-04-24
Abstract: The explosive-actuated driving tool has a channel (7) between a piston guide (2) for a piston (1) and a housing part (6). This channel (7) continues opposite the driving direction in a support (3) and is connected to a cartridge receptacle (4). On the driving-direction side, the channel (7) is connected via an opening (2c) in the piston guide (2) to the guide bore (2a) for the piston (1). Provided in the channel (7) is a valve device which serves to connect the regions, on the driving-direction side, of the channel (7) and the guide bore (2a) to form a storage space closed to the atmosphere. The propellent gases enclosed in this storage space are compressed by the piston (1) and serve, after completion of the driving-in operation, under expansion, to return the piston (1) to its rear starting position. A passage (3a) connects the spaces, adjoining the piston (1) opposite the driving direction, to the atmosphere so that these spaces are sufficiently vented, which on the one hand leads to unhindered driving-back of the piston (1) into its rear starting position and on the other hand allows a residual proportion of the explosive gases to escape. <IMAGE>
