Patent DE-1810646-B2 (DE)
Title: D.C. voltage reduction cct. - is suitable for matching D.C. motor rotor voltage to drive voltage
IPC: H02M3/135
Filed: 1968-11-23
Abstract: Circuit arrangement for converting a direct voltage into a lower direct voltage, as may be required in d.c. motor drives for matching the speed-variable armature or rotor voltage to the drive voltage, is described. Conversion is carried out by means of a switch, periodically switching on and off, which, together with a choke in series with the switch, is connected into a series circuit comprising the direct voltage input and the load. A free-running diode is connected in parallel with the series circuit comprising the choke and load. The choke has a non-linear, i.e. sharp bend shaped magnetisation characteristic and at full load current the working region of the circuit lies on the bend of the characteristic.

Title: Open type container ship - with container stacks replaced with open profile boxes to carry bulk cargo
IPC: B63B25/00
Filed: 1968-12-23
Abstract: The open holds of the double hull container ship are fitted with an array of vertical struts (8) which locate the corners of the containers, which are stacked in vertical stacks. If the ship is to take bulk cargo then special boxes are slid into the stacks. These have no bottoms and sides and serve to contain the bulk cargo and prevent it sliding about at sea. The boxes can be empty containers which are designed with removable floors and roofs. The system also enables mixed cargo to be taken. The system is partic. of use where only a partially full load is to be carried.

Abstract: 1426918 Laminates STANDARD OIL CO 30 April 1973 [9 June 1972] 20425/73 Heading B5N [Also in Division H1] An electronically conducting, ionically insulating current collector or inter-cell connector for a capacitive device (see Division H1) comprises a layer of conductive carbon black loaded elastomer sandwiched between two flexible graphite layers. The graphite layers are each preferably 0À3 tp 10 mils. thick and may have anisotropic conductivity. The elastomer layer may be 2 to 10 mils. thick. The elastomer may be a natural or synthetic rubber, examples of the latter being disclosed, and may include promoters, e.g. nitroso-compounds, to increase its conductivity. The elastomer layer may be applied to one of the graphite layers, optionally as a solution, by calendering, silk screening, spray or brush coating. Alternatively a sheet of the elastomer, prepressed or calendered to desired thickness, is placed between the two graphite sheets. The laminate is consolidated by pressure prior to curing the elastomer by nuclear, ultra-violet or infra-red radiation, steam, hot air or vulcanizing. Comparative examples disclose a single graphite sheet laminated to the loaded elastomer, the latter having a smooth or a roughened surface.
Patent JP-H0239864-B2 (JP)
IPC: H01L21/58
Filed: 1984-04-05
Abstract: PURPOSE:To prevent the remaining of air bubbles on the adhesion surface and the deposition of solder to the side surface of a chip by a method wherein a fused solder layer with the arrangement of a swelling on a straight line passing through the center of the thin film part is provided on a substrate more widely than a chip, and is then slidden under pressure. CONSTITUTION:A head 3 has many pyramids only on quadrisection sector planes 3a1 and 3a2 in the direction of diameter 7. After the head 3 is made to abut againt the fused solder 2 dripped down on the substrate 1 and the shaft 9 is rotated 10, an index 11 is detected 12 and the rotation is stopped when opposed sides 5a and 5b of the chip come to agree with the direction of the diameter 7. On the pull-up of the head 3, the solder swelling 2b and the thin film 2b are produced along the straight line 7a. The chip 5 is arranged on the fused solder 2 thus formed so that the sides 5a and 5b do not come into contact with the swelling 2b, and the chip 5 held by a collect 4 is reciprocated 13 in the pressing direction 7a and the rectangular direction 8a. At this time, the sides 5c and 5d contact the swelling 2b; however, the amount of infiltration of the solder is small because of agreement with these sides in the direction of reciprocation. Therefore, the solder does not deposit on an adsorption opening at the time of collect pull-up, thus allowing no contamination to the side surface of a next chip. Besies, air bubbles are smoothly pressed toward the side of the swelling 2b.

Filed: 1988-03-31
Abstract: The invention solves the problem of pattern recognition in a temporal signal that is subject to distortions and time warp. The arrangement embodying the invention comprises a neural network, an input interconnection network, and a plurality of signal modification circuits. A plurality of input leads delivers a preselected characteristic stimulus to associated signal modification units, and in response to an applied stimulus, each signal modification unit develops a plurality of output signals that begins at the time of stimulus application, rises to a peak, and decays thereafter. The mean time delay of each output (time to reach the peak) is different for each of the modification unit output signals. The outputs of the signal modification units are applied to the input interconnection unit wherein connections are made in accordance with the sequences that are to be recognized.
