The present invention provides an image engraving apparatus capable of precisely driving a stylus to improve accuracy of image engraving. The image engraving apparatus has a vibration actuator fixed to a floating base and having an output portion configured to output vibration generated by deformation of piezoelectric elements, a stylus supported with a stylus holder to be vibrated and engrave an image on a medium to be engraved, a supporting spring supporting the stylus holder, and a retainer positionally adjustably supported to the floating base to come into contact with the medium.

A tool including a tool surface and further including coding indicia linked, at least indirectly, with the surface of the tool, the coding indicia capable of being detected by a sensor, the coding indicia functioning as a pointer to information relating to said tool or its use.

The invention relates to a portable appliance for marking a surface, the appliance comprising a housing (2) presenting a front face that is open for passing a marker member that is moved by a device for moving the marker member in a two-dimensional marking zone (Z). The housing is provided with a positioning nose (30) for positioning the appliance over the surface for marking, the positioning nose defining firstly the two-dimensional marking zone (Z) facing the front face of the housing and at a distance from the front face, and secondly an opening (35) extending the top wall for enabling the two-dimensional marking zone to be viewed, the top wall of the housing being fitted with a display screen in such a manner that the screen and the two-dimensional marking zone as seen through the opening of the positioning nose appear simultaneously in the field of view of an operator.

The present invention provides for a wall mountable system for automated drawing of an image upon a wall which includes a horizontal mounting track for mounting on a wall, a robot having a y-track rigidly mounted it where the robot and the mounted y-track travel along the horizontal track. An end effector, which includes a pen holding mechanism holding a pen, is in electrical communication with the robot and travels along the y-track of the robot. The present invention provides a system and device that can attach to a wall or vertical surface in a damage-free manner and draw fast any complexity or style image of custom size in both the horizontal (X) and vertical (Y) directions, that is easy to remove and transport and require small floor space to operate.

A connector and labeling forming method thereof is provided. The method includes: a laser engraving device generating a laser beam, and controlling the laser beam to engrave a label on a labeling part of a metal shell of a connector. The connector includes a metal shell and a label. The metal shell has a labeling part and the label is engraved on the labeling part by a laser beam. As such, the invention can engrave the label on the labeling part of the metal shell of the connector by using the laser engraving technology to replace the traditional self-adhesive label, thereby being able to solve all the problems caused by the self-adhesive label.

The present invention provides a vibration generator capable of accurately adapting to fine vibration. The vibration generator has a stationary permanent magnet, a yoke for the permanent magnet, a coil fixed to the yoke, four springs provided to the yoke, and a movable piece supported with the yoke through the four springs. The end portions of the movable piece are arranged between the respective two pairs of the projections with first gaps. The central portion of the movable piece is arranged in the through-hole with the second gaps, the second gaps having a size to allow oscillation, which is regulated by the first gaps, of the central portion of the movable piece.
