摘要： An integrated optics chip eliminates problems caused by polarization cross coupling in fiber optic rotation sensors without requiring time consuming and expensive alignment of the axes of the optical fiber sensing coil and the optical waveguides formed in the integrated optics chip. A substrate formed of an optically active material has slots formed therein for mounting optical fibers to the substrate. An optical waveguide is formed in the integrated optics chip to guide optical signals along a selected axis of propagation such that an end wall of the slot includes an end surface of the optical waveguide. The end surface of the optical waveguide is formed to make an angle with the direction of propagation of light in the optical waveguide to reduce the amount of light reflected at the end surface of the optical waveguide. The angle of the end of the optical waveguide is formed such that light reflected at the interface back into the optical fiber impinges on the core/cladding boundary at an angle that permits refraction from the core into the cladding. The angle of the end of the optical waveguide preferably is in the range of 5.degree. to 25.degree..

摘要： A transmission mechanism for an electric nail gun includes a linear transmission unit and a rotary transmission unit in a housing of the electric nail gun. The rotary transmission unit includes an electric driven driving wheel. The linear transmission unit includes a rack and a hitting bar. The hitting bar is disposed at a bottom of the linear transmission unit. The rack is in mesh with the driving wheel, slidably installed in the housing by a spring force, and configured to receive driving from the driving wheel and to drive the hitting bar to move linearly downward so as to hit a nail.

摘要： A transmission mechanism for an electrical nail gun includes a rotary transmission unit and a linear transmission unit in a housing of the electrical nail gun. The rotary transmission unit includes a motor driven by electricity, a flywheel driven by the motor and extending to form a cylinder thereon, a solenoid activated by electricity, and a moveable driving wheel adjacent to an end side of the cylinder. A clutch is formed between the cylinder and the driving wheel. The solenoid is buried in the cylinder so that a magnetic conductivity loop is constructed around the solenoid to produce the magnetic field when the solenoid is activated. The driving wheel is attracted to move to an engagement position to be driven by the flywheel, thereby driving the linear transmission unit to impact a nail when the solenoid is activated by electricity, and the driving wheel returns to a disengagement position to disengage from the flywheel, thereby stopping driving the linear transmission unit when the solenoid is demagnetized.

摘要： A rare-earth doped glass waveguide is optically pumped to produce superfluorescent light. The waveguide is formed in a glass substrate. The pump light is input to a first end of the optical waveguide, and the output is emitted from the other end. A grating formed on the waveguide near the output end reflects the pump light to separate the pump light from the output light.
