Patent CA-2111752-C (CA)
Inventor: ROBINSON JAMES W
IPC: B25C1/00
Filed: 1993-12-17
Granted: 1996-02-13
Abstract: In a fastener-driving tool, a primary structure, an intermediate structure, and a secondary structure are movable separately along a tool axis.  The primary structure is biased to a tool-disabling position, movable along the tool axis to a tool-enabling position, and engaged by an upper end of the intermediate structure.  The secondary structure has a lower end to be firmly pressed against a workpiece.  A bolt is threaded adjustably into an axial socket of the intermediate structure.  A spring disposed around the bolt shank, between the bolt head and a flange on the secondary structure, biases the intermediate structure in one direction.  The bolt head has flat surfaces, one of which is engaged by a tab on another flange on the secondary structure to prevent bolt rotation unless the secondary structure is moved against the spring bias, whereupon the bolt can be then rotated.

Abstract: A gas lighter with a safety device is provided with a resilient leaf which can be deformed between a locked state in which the depression of a pressing means is prevented and a lock-released state in which the operation of the pressing means is allowed, and a slide member which is fitted around the resilient leaf and is movable between a first position where ignition operation is impracticable when the resilient leaf is in a locked state and a second position where the ignition operation is practicable.  The slide member deforms the resilient leaf and renders it in a lock-released state at a third position which is reached during movement from the second position to the first position in response to ignition operation.  The gas lighter is also provided with a deformation suppressing means for reducing the amount of deformation of the resilient leaf obtained when the slide member is located at the second position so as to be less than the amount of deformation of the resilient leaf in a lock-released state when the slide member is located at the third position.

Title: Golf ball teeing device
Inventor: DERMOTT JOHN R
IPC: A63B57/10
Filed: 1994-03-23
Granted: 1999-04-06
Abstract: A device for teeing a golf ball automatically and in portable form. It is a complete unit consisting of a hopper for holding a plurality of balls, guides and blockers to prevent the balls clogging in the hopper, a rotor and pendulum to release one ball at a time, an automatic actuation of the ball release, a pivoting ramp to place a ball on an integral tee and a connection to the tee so that when the ball is struck with a golf club, the next ball will automatically proceed to the tee. The flow of a ball to the tee is accomplished by gravity due to the elevated hopper and the force of the golfer's swing. The device is mechanical and does not require electric power nor batteries and is completely automatic since no separate operation is required to send the ball to the tee.

Abstract: A loading box adjustable in zones thereof for a former of a paper or board machine. The former comprises a twin-wire section including two wires placed one above the other and running in the same transfer direction. In the twin-wire section, a drain box is mounted at one side of the wires to remove water out of a fibrous pulp running between the wires. At the opposite side of the wires, a loading box is mounted and is provided with loading ribs arranged in the transverse direction in relation to the transfer direction and which extend across the web width. The loading ribs are loaded toward the bottom of the drain box in order to produce a desired compression in the fibrous pulp running between the wires. The loading box is provided with loading members arranged to produce a locally raising or lowering force applied to the loading ribs in the direction transverse to the transfer direction. The force is applied simultaneously to at least two successive loading ribs to profile the compression force applied by the loading ribs to the fibrous pulp in the transverse direction.

Granted: 2001-03-13
Abstract: The present invention relates to an echo canceler for training an echo path estimation without providing a hindrance to a speech. The echo canceler of the present invention includes a pseudo noise generator for generating a certain pseudo noise. This pseudo noise is forcibly supplied to a transmission line for transmitting a far-end talker's voice. Here, in the case where the far-end talker's transmitting speech level is faint or the far-end talker is in a speechless condition, a certain correlation is established between the pseudo noise and a signal of the transmission line for transmitting the near-end talker's voice. Based on such a correlation as just mentioned, a coefficient for generating an echo replica is calculated.    Therefore, a training for estimating an echo path is performed based on the pseudo noise and without depending on the far-end talker's voice, thereby generating an appropriate echo replica.

Title: A celp-type speech encoder having an improved long-term predictor
Inventor: FUNAKI KEIICHI
IPC: G10L25/90
Filed: 1995-12-27
Granted: 2000-08-01
Abstract: A speech signal encoder includes a speech analyzer for determining short-term prediction codes at a predetermined time interval.  The prediction codes indicate frequency characteristics of a speech signal. A reverse filter is provided for calculating residual signals of first synthesis filter.  The residual signals is defined by the short-term prediction codes.  A residual code book stores past residual signals. Further, a plurality of delay codes, each of which represents pitch correlation of the speech signal, are tried a predetermined number.  A vector generator issues, using the residual code book, delay residual vectors each of which corresponds to the delay code.  A filter is provided for generating a synthesis signal using second synthesis filter which receives the delay residual vectors and which is defined by the short-term prediction codes.  A distance between the speech signal and the synthesis signal is calculated.  Subsequently, a pitch path estimator estimates a pitch path which varies smoothly. The pitch path thus estimated is used for determining a delay code.
