Patent EP-0007420-A1 (EP)
Inventor: DIETERLE GERHARD
IPC: H01H47/00
Filed: 1979-06-13
Abstract: A safety circuit for a potentially dangerous machine (M) monitored by light and which works in an operating cycle. A safety circuit is described which utilises a series of relays (A, B, C, D, G) each of which is switched from an energised to a de-energised condition once during each working cycle of the machine so that each of the relay contact also opens and closes during the working cycle. In this way each relay contact is tested. The relays are so interconnected that if one contact should stick it will interrupt the sequence and will ensure the potentially dangerous machine e.g. a press is rendered inactive. Circuits are given for both hand fed and automatic machines which are monitored by a light barrier or curtain (17). For the hand fed machine the cycle is initiated by the operator reaching through the light barrier to insert an object into the machine. For an automatically fed machine the test cycle is initiated by a switch (27) automatically activated once per cycle.

Un second membre conducteur magnetique (13) constitue un element de support d'armature porte sur la structure isolante de support (10) ayant une direction generale alignee avec le premier membre mais separee de ce dernier. Le deuxieme membre conducteur magnetique a aussi une structure en gradin concretisee par une extension conductrice magnetique (13a) decalee lateralement de l'alignement axial, du meme cote que l'extension (11b) du premier membre magnetique conducteur. Une armature magnetique (15) s'etend entre le premier et le second membre magnetique conducteur et possede une longueur telle qu'elle chevauche les portions qui s'etendent axialement, de chaque membre magnetique conducteur et s'ajuste dans chaque gradin en evitant cependant le contact.

Abstract: The method is applied after the contact region (27a) has been covered by a silicon nitride oxidation blocking mask (28a) which subsequently was subjected to oxidation and/or doping processes causing the formation of various compounds in the silicon nitride (28a) and at the interface between the silicon nitride (28a) and the contact region (27a). A non-selective etching process is used to remove silicon nitride (28a) and the formed compounds. In particular it has been found that a plasma comprising a organo-halide and an excess of oxygen can be used to non-selectively etch the silicon dioxide, the silicon nitride, its associated compounds and the material of the contact region, like polysilicon. The method is useful e.g. for the formation of the polysilicon gate of a silicon field effect transistor.
