Title: PIN diodes collectively made from PIN chip - are formed between electrodes by etching parallel trenches in two stages followed by separation
IPC: H01L23/31
Filed: 1973-03-09
Abstract: The PIN diodes are constructed from a PIN chip sandwiched between two electrode layers and supported by a metal base. Parallel trenches are etched down through the top electrode and over halfway through the PIN chip to separate out the individual PIN diodes. A second longer etching process removes part of the PIN material from underneath the edges of the discrete top electrodes to form Ts and deepens the trench to reach the lower electrode. The T structures and trenches are then covered in a layer of passive material. This material is then removed from the tops of the upper electrodes. The metal base is finally removed and the diodes are separated from one another.

The prepn. of the additives is by reacting a di-organo dithiophosphoric acid with the cyclic olefin.
Patent FR-2225821-A1 (FR)
Title: Electric capacitors with metallised dielectric foil - longer life obtd. by thickening metal along border or leakage path
IPC: H01G4/38
Filed: 1973-04-13
Abstract: A metallised dielectric, esp. a metallised plastic foil, where a zone of the foil-surface along >=1 edge, is not metallised, and an increased thickness of metallisation is used along the border of this zone. This type of construction avoids the continuous drop in capacitance, with time, which occurs in use, due to the deterioration of the metallisation along the leakage-path. The technique is quite distinct from the thickening of metallisation for contact purposes, and is esp. applicable to polymer plastics, e.g. polystyrene, polyethylene, polycarbonate, etc. with vacuum-deposited Al or Zn. The increased thickness can be up to ten times the thickness of metallisation away from the border, pref. at least double. The beneficial effects are partic. noticeable in non-impregnated condensers in A.C. cicuits.

Title: Device to tighten binding round packages - has one end of strip held loosely to permit slight relative movement at first use
IPC: B65D45/34
Filed: 1974-07-26
Abstract: The device is of the type in which a pivoting handle (2, 3) serves to tension a surrounding strip (6, 7). The ends of the strip are passed through slots, the free ends lying between the strip and the container. One free end at least is only loosely attached (10) so that during initial use a relative movement of the parts of the strip can occur. This serves to release the load if it becomes too high. If one free end is welded (13) against the strip, then this end is used to carry the greater load applied during the tightening process.
