Patent CA-1279406-C (CA)
Title: Token passing network
Inventor: ROACH MONTE J
IPC: H04L12/417
Filed: 1987-03-17
Granted: 1991-01-22
Abstract: Abstract of the Disclosure A programmable controller is adapted to communicate in a token passing logical ring network in a peer-to-peer fashion.  The programmable controller is a station on the network and contains an interface which implements the network protocol.  The protocol requires that each station maintain an Active Node Table which stores a complete map of the logical ring and the order in which the token is passed.          The Active Node Table is automatically updated by monitoring each token pass on the network, where each token pass identifies the source and destination of the token pass.      The Active Node Table is used in performing all routine network maintenance functions, including passing the token, adding stations, and dropping stations.  The Active Node Table allows the formation of an Active Node Status Word for use by high level processes within the station.  The Active Node Table also facilitates the inclusion of data in the token pass message.

Abstract: PCT No. PCT/FR87/00273 Sec. 371 Date Mar. 10, 1988 Sec. 102(e) Date Mar. 10, 1988 PCT Filed Jul. 9, 1987 PCT Pub. No. WO88/00744 PCT Pub. Date Jan. 28, 1988.The subject of the invention is a method for diversification of a basic key and for authentication of a thus-diversified key as having been fashioned on the basis of a predetermined basic key, and a system for performing the method. An initializing system calculates a diversified key (Sd) on the basis of a basic key (Sb) processed by a biunique combination transformation (T). The key (Sd) recorded in the memory (M3) of a user card (CU3) is authenticated by an exploitation system (4), which calculates a certificate on the basis of the basic key (Sb), while the card (CU3) calculates a certificate on the basis of its key (Sd). These certificates must be identical, taken into account the properties of the transformation (T). The invention is applicable in particular to the secret keys recorded in memory cards.

Title: Method for manufacturing wells for cmos transistor circuits separated by insulating trenches
Inventor: MAZURE-ESPEJO CAROLS-A
IPC: H01L21/82
Filed: 1988-08-02
Granted: 1991-08-13
Abstract: ABSTRACT OF THE DISCLOSURE        A double well CMOS process wherein the wells are separated by insulating trenches introduced into a semiconductor substrate, the position of the insulating trench along the isotropic under-etching in a silicon oxide layer employed together with a silicon nitride layer used as a masking layer in the implantation of the well which is first implanted.  The trench itself is produced by anisotropic etching with silicon oxide masks used in the well implantations as etching masks.  The trench width is defined with the isotropic etching and the trench depth is defined by the anisotropic etching.  In this method, both well implanatations and the trench etching are carried out with only one photo-technique.  The implantation of the second well and the trench etching are self-adjusting.  As a result, minimum spacings between the active zones are provided, and a space saving design is possible.  The method is used in LSI CMOS processes.

Patent CA-1310281-C (CA)

IPC: B60T7/10
Filed: 1988-09-06
Granted: 1992-11-17
Abstract: ABSTRACT           An improved self-adjusting mechanism for a cable-operated vehicle brake is disclosed.  The operating lever is pivoted about an axis on a frame member which carries a fixed sector.  The lever carries a first pawl, which is adapted to releasably hold the operating lever in position with respect to the frame, and a second pawl which locks the lever to a sheave sector fixed to a sheave which winds up the brake cable upon pivoting of the lever.  A third sliding pawl is mounted on the sheave sector.  When the operating lever is rotated beyond a predetermined degree in setting the brake, the sliding pawl abuts a stop on the frame.  This moves the sliding pawl with respect to the sheave sector.  When the handle is subsequently returned to its rest position, the sliding pawl allows a limited amount of rotation of the sheave sector with respect to the lever, which occurs due to tension exerted on the brake cable by the brake shoe return spring.  In this way predetermined limited amounts of slack in the cable are automatically taken up, and excessive spring force on the cable is avoided.
