An in-line skate includes a sole plate having wheels rotatably connected to the underside of the sole plate and two elongated first slots are longitudinally defined through the sole plate. A rear portion of vamp is connected to a connection wall on the sole plate. A toe part has two elongated second slots longitudinally defined therethrough and a front portion of vamp is connected to the toe part. The toe part is connected to a top of a front end of the sole plate. Two adjusting members extend t...

An infant training walker has a base platform, a disk-shaped tread member rotatably supported approximately flush therewith, and a belt-shaped restraint spaced above the platform in eccentric relation to the tread member for laterally restraining an occupant of the walker. Preferably, a seat element having leg openings depends from the restraint, and the restraint is rotatable within a tray having an array of toy elements. Thus the occupant is encouraged to exercise in a variety of angular orien...

A positioning device for a walking chair is able to provide a positioning effect on the walking chair, so that a baby sitting within the walking chair will not be able to rotate freely with the walking chair, and thus the safety of the baby is ensured.

A walking-type exerciser including two mounting seats, a detachable first supporting frame member connected to the mounting seats, a second supporting frame member detachably attached to the mounting seats, a handle detachably connected to the mounting seats, and two rocking devices detachably mounted to the mounting seats.

The invention relates to an automatic optical fiber stripping machine and, more particularly, to an automatic optical fiber stripping machine, which is practical for stripping optical fibers of different diameters efficiently. The automatic optical fiber stripping machine helps the user obtain the desired length of bared glass core for further standardized coupler, optical passive component manufacturing, and accurately strips optical fibers of different diameters without damaging the glass core...

A wheel hub to be used in a golf motor caddie, has an axle; an outer tube, having a first end with a small opening, a second end with a large opening and three sections containing a first, a second and a third chambers, with an inner circular groove cut into the outer tube close to the second end; an inner tube, surrounding the axle; a first, plastics bearing, inserted in the first chamber; a second bearing, inserted in the second chamber; a third, oil-lubricated bearing, inserted in the third c...

The present invention provides a method of fabricating strained silicon channel MOS transistor, comprising providing a substrate, forming at least a gate structure on the substrate, forming a mask layer on the gate structure, performing an etching process to form two recesses corresponding to the gate structure within the substrate, performing a selective epitaxial growth (SEG) process to form an epitaxial layer in the recesses respectively, and performing an ion implantation process for the epi...

An active pixel sensor. A solid state radiation detection unit may be fabricated using a semiconductor substrate having a plurality of CMOS pixel circuits incorporated into the substrate. An array of pixel circuits includes within each circuit a charge collecting pixel electrode, a charge sensing node, a gate bias transistor for separating the charge collecting pixel electrode and the charge sensing node and for maintaining the pixel electrodes at substantially equal potential, and a pixel capac...

A MOS or CMOS based photoconductor on active pixel image sensor. Thin layers of semi-conductor material, doped to PIN or NIP photoconducting layers, located above MOS and/or CMOS pixel circuits produce an array of layered photodiodes. Positive and negative charges produced in the layered photodiodes are collected and stored as electrical charges in the MOS and/or CMOS pixel circuits. The present invention also provides additional MOS or CMOS circuits for reading out the charges and for convertin...

The present invention embodies a safety interlock system and method for automatically disabling operation of a robot or other machine with standard mechanical interfaces (SMIF) apparatus if the components are not in proper operating positions when the machine is started. In a preferred embodiment the safety interlock is incorporated in a robotic machine for processing semiconductor wafers and the system uses three conventional sensors for detecting whether the transfer robot is in the out positi...
