Title: Reinforcing bar binding machine, wire reel, wire, and method of determining kind of wire
Inventor: NAGAOKA TAKAHIRO
IPC: B65B13/02
Filed: 2005-04-27
Granted: 2009-06-16
Abstract: A wire reel containing portion 3 of a reinforcing bar binding machine 1 is provided with a rotation detecting lever 8 and a photosensor 7. When a wire reel is rotated in starting to bind a wire, rotation thereof is detected by the rotation detecting lever switched ON/OFF by a projected portion formed at a side face of the wire reel, the photosensor detects a reflection mark of the wire reel to determine a kind of the wire from a number of the marks, and a twist torque or the like is controlled. Wire information is detected not in an initializing operation (in setting wire) of rotating the wire reel at low speed but in a binding operation of rotating at high speed and therefore, an amount of swinging the rotation detecting lever is large and wire information can firmly be detected.

Abstract: Systems and methods are provided for precorrecting a constant envelope input signal. A phase precorrection component generates a precorrected input signal by applying a phase precorrection to the input signal.

Granted: 2010-09-14
Abstract: In the safety cutter knife provided, a blade slide holding a blade is rotated in the direction nearly perpendicular to the longitudinal center line of the housing of the cutter knife by virtue of a reaction force from a work material when the cutting edge of the blade extended from the housing is pressed into the work material while the blade slide and the actuator slide are located at the extended position. With this rotation of the blade slide, the engagement between the blade slide and the actuator slide is released, such that the blade slide with the blade can return automatically from the extended position to the retracted position by virtue of the energizing force of a spring when the blade is released from the work material.

Abstract: L'invention concerne un détecteur, compact et de longue durée de vie, permettant de mesurer des caractéristiques, telles que l'humidité dans les feuilles en déplacement, y compris du papier dans un appareil de fabrication de papier. Ce détecteur utilise des sources lumineuses qui produisent des rayonnements dans des plages de longueurs d'ondes définies, ces sources de lumière étant modulées à des fréquences élevées par des techniques non mécaniques. Un détecteur unique ayant des sources de rayonnement diverses peut mesurer à toutes les fréquences tout en gardant les informations séparées. Une diode émettant une lumière superluminescente ou des sources lumineuses de diode laser peuvent être directement électriquement modulées pour une meilleure élimination du bruit. Ces sources de puissance élevée et de lumière intense offrent une excellente efficacité de lancement de la fibre optique et permettent au détecteur d'être scanné à des vitesses nettement plus rapides sur le papier surveillé.
