Patent CA-2189712-A1 (CA)
Inventor: ICHIHARA MASAKI
IPC: H03G3/10
Filed: 1996-11-06
Abstract: A variable gain amplifying device for an AGC (Automatic Gain Control) circuit included in a receiver and having a broad dynamic range is disclosed. The device has a more linear gain-to-control voltage characteristic than the conventional device. Because the device broadens the range of control voltage without aggravating the deviation of the gain, its gain-to-control voltage characteristic is more stable than the characteristic of the conventional device.

Title: Apparatus for and method of recording information on or reproducing information from recording medium
Inventor: YAMAKAWA AKIO
IPC: G11B7/13
Filed: 1996-11-06
Abstract: A laser diode applies a laser beam through a grating, a beam splitter, and an objective to a compact disc. A laser beam reflected by the compact disc is applied through the objective and the beam splitter to a photodiode. The objective has a large numerical aperture of 0.6 in order to be able of play back a digital video disc that has a thin substrate and contains information recorded at a high density. To prevent the photodiode from suffering aberrations caused due to the large numerical aperture of the objective, the photodiode has a relatively small photodetector unit having a normalized detector size ranging from 3 .mu.m to 16 .mu.m, for detecting only returning light up to a numerical aperture of 0.3 and not detecting light of greater numerical aperture values.

Abstract: La présente invention concerne un procédé et un ensemble permettant le transport de modules (13) constituant une cabine de bateau, et des composants similaires, dans des bateaux, des structures offshore et des bâtiments construits sur la terre ferme. Selon l'invention, trois montants (3) pourvus de roues (4) sont fixés aux modules (13) à transporter. A cet effet, les montants sont fixés par leur extrémité distale, par rapport aux roues (4), à la partie extérieure des modules (13), de sorte que la distance séparant le point de fixation et le bord inférieur du module (13) soit plus petite que la longueur maximum du montant (3), longueur qui est mesurée entre le point de fixation et le point le plus bas de la roue (4). Une sangle de serrage (1) est conçue pour entourer le module (13) et pour passer dans des boucles (5) formées sur les montants (3). Lorsque l'on serre la sangle (1), les montants (3) se rapprochent du module (13), et que l'on fait monter celui-ci au moyen des montants (3) jusqu'à sa position de transport.

Title: Thyristor power control circuit
Inventor: LEE WADE
IPC: H03K17/725
Filed: 1995-06-26
Abstract: A circuit arrangement and method for firing a gated thyristor (13) used for applying electrical power to a load (14), in response to a trigger signal, from a live power lead (11) and a neutral power lead (10) such as found in the common household electrical service. The load to be energized in response to the trigger signals is connected between the neutral power lead (10) and one of the thyristor main terminals (22), the other thyristor main terminal (21) being connected to the live power lead (11). The live power lead is biased at a negative potential with respect to the neutral power lead to define a circuit ground at the negative potential. A gate circuit (31, 32, 34) is connected between the gate terminal (23) and the circuit ground for applying a potential to the gate terminal in response to the trigger signal that is at least as great as the thyristor's characteristic threshold potential for enabling current flow between the thyristor main terminals and thereby energizing the load. The potential applied to the gate terminal is thus negative with respect to the neutral power lead. In one embodiment the gate circuit is provided by a single transistor (31) switched on by the trigger signal and connected in line with a diode (34) and resistor (32) between the gate terminal and the circuit ground.

Title: Key cutting machine for cutting keys by code
Inventor: BEAUREGARD ALAIN
IPC: B23C3/35
Filed: 1997-01-15
Abstract: A key cutting machine for cutting keys by code has a vise jaw for securely holding a key with a groove of the key aligned with respect to the vise jaw and with at least one of a tip of the key and a shoulder of the key positioned at a predetermined position with respect to the vise jaw, a key cutter, a position detector for detecting a blank edge of the key held by the vise jaw, a movement system for moving the key cutter and the vise jaw relative to one another to cut the key; and a controller for controlling the movement system to carry out a predetermined sequence of movements according to code information. The code information is referenced with respect to a blank edge of a side of the key to be cut, and the predetermined sequence of movements being referenced to the detected blank edge position. A key is cut with the key held in the vise jaw with a groove of the key aligned with respect to the vise jaw without needing to align the key with respect to a keyrest. For a double sided key having standard code information, the key is placed against a keyrest and the position detector is used to determined the width of the key. The second side of the key is then cut with the key held in the vise jaw with a groove of the key aligned with respect to the vise jaw without needing to align a remaining blank side with respect to a guide. For a double sided key having code information including a width parameter of the key blank, the key is placed against a keyrest and the position detector is used to determined the actual width of the key blank. The predetermined sequence of movements is then modified to compensate for differences in key blank width.

Title: User Authentication in a Communications Network
Inventor: HARDING PETER MAXWELL
IPC: H04L9/32
Filed: 1995-08-16
Abstract: An authentication system of a terminal on a public switched telephone network comprises a security node associated with a local exchange (10) and a network terminal (14). For one-way authentication, the terminal (14) responds to a call initiation by sending a unique authentication code (R) comprising a number (m) and a secret key (S¿j?) encrypted according to a first algorithm (F), the secret key being specific to the terminal. The security node constructs the expected authentication code (E) from the number (m), using the first algorithm (F) and a second key which is a function of a terminal identification number (TN), and compares the expected code (E) with the received code (R). In two-way authentication, the security node responds to the call initiation by sending a transaction number (n) to the terminal (14) encrypted according to a second algorithm (f¿j?). The terminal (14) generates the authentication code (R) as a function of the first algorithm (F), the secret key (S¿j?) and the transaction number (n). The authentication code (R) is sent back to the security node. An expected code (E) is compared with the received one (R) in the same way. In both cases, a match between expected and received authentication codes (E and R) constitutes authentication of the terminal (14), allowing the user access to the network.

Inventor: PACE LOU
IPC: G11B21/02
Filed: 1997-02-25
Abstract: An improved actuator apparatus is employed in a hard disk drive device for positioning read/write heads over tracks on a data storage disk of the disk drive. The actuator apparatus includes an all plastic C-block assembly providing the actuator apparatus with a reduced weight, lower inertia and better damping characteristics which enable improved dynamic performance. The C-block assembly includes a body portion and a pair of tapered support arms extending from the body portion in a parallelorientation. The support arms each have a read/write head staked thereto within a mounting surface aperture at a distal end of the arm. The mounting surface aperture is configured to have a non-circular shape to facilitate staking of the read/write head to the support arm and enable construction of the C-block assembly out of plastic. The non-circular shape of the mounting surface aperture additionally enables swaging within the aperture of the plastic support without causing the plastic support arm to break or crack.

IPC: B65H23/02
Filed: 1995-10-03
Abstract: The invention relates to a method and apparatus for guiding a thin web material (I) while folding the web material (1) over a triangular former (4). The apparatus includes two guide rolls (2, 3) over which the web material (I) is driven. The second guide roll (3) is secured to a baseline (5) of the triangular former (4).
