Title: Stacked varactor diodes for microwave applications - using two silicon substrates with doped epitaxial layers
Inventor: HENRY RAYMOND
IPC: H01L25/07
Filed: 1975-08-19
Abstract: Stacked microwave diodes are made using at least two semiconductor slices, the lower slice (1) being strongly doped n+ or p+ and soldered onto a heat sink; slice (1) is provided with a less strongly doped layer (Z1). The second slice (2) is of opposite conductivity, p+ or n+, and given a less strongly doped layer (Z2).

More than two slices may be used in the stack. In a pref. process, layers (Z1,Z2) are formed by epitaxy, followed by the n+ or p+ layer and a metal layer; the two metal layers are joined by thermo compression bonding; slice (2) is then lapped until its thickness is similar to that of layer (Z2), and both slices are metallised, followed by etching to obtain mesa structures.
Patent FR-2282574-A1 (FR)
Title: Drum brake automatic adjusting arrgmt - avoids faulty adjustment due to drum expansion
IPC: F16D65/54
Filed: 1975-08-19
Abstract: The adjusting arrangement consists of two strips with ratchet teeth which engage with one another. One strip is attached to the head braking lever. The lever is connected directly with one of the brake blocks and via a connecting rod to the other brake block. A bent lever is connected at one end with one of the ratchet tooth strips and at the other end to a roller which engages with the inside of the brake drum. The angular movement of the bent lever is limited by a stop. The amount of angular play is proportional to the brake play. When the brake is operated, the toothed strips move to one side and the roller will be pushed against the brake drum. If the drum expands, the roller will follow the drum, the toothed strips will move further to one side but cannot move relative to one another. This only occurs when the brake shoes wear down.

Title: Mfr of cages for roller bearings - where roller pockets are blanked out of strip and the webs crimped to form retaining ears
Inventor: DOPPLING HORST
IPC: F16C33/46
Filed: 1975-08-21
Abstract: Process for mfg. a roller-bearing cage for cylindrical rollers, starting from flat strip which is bent after forming the pockets in which the rollers are located.

Economic prodn. of bearing cages using thin strip as the ears project beyond both surfaces of the strip.

Patent FR-2335796-A1 (FR)
IPC: F23N5/08
Filed: 1976-12-20
Abstract: In the control and monitoring device, the flame monitoring circuit is designed for great sensitivity, and this circuit only assumes a normal sensitivity adapted to the flame by application of a voltage to an additional connection (11).
