摘要:
A single-sided shuttle-type blow molding apparatus having an extruder for substantially continuously extruding a thermoplastic material in tubular form at a moldable temperature downwardly along a vertical axis. The apparatus includes a mold having a set of mold parts adapted to open and close relative to each other to define, when closed, a mold cavity. A shuttle having the mold mounted thereon is arranged to move along a closed path from a first position wherein the mold engages, when open, a finite length of the thermoplastic tube, to a second position away from the first position. The apparatus further includes a blow head adapted to blow the finite length of the thermoplastic tube to form the container as the mold moves from the first position to the second position of the closed path. The apparatus includes no more than one mold. A method is also described.

The present disclosure provides a process for manufacturing a solar cell by selectively freeing an epitaxial layer from a single crystal substrate upon which it was grown. In some embodiments the process includes, among other things, providing a first substrate; depositing a separation layer on said first substrate; depositing on said separation layer a sequence of layers of semiconductor material forming a solar cell; mounting and bonding a flexible support on top of the sequence of layers; etching said separation layer while applying an agitating action to the etchant solution so as to remove said flexible support with said epitaxial layer from said first substrate.
摘要:
An optoelectronic module for converting and coupling an information-containing electrical signal with an optical fiber including a housing having an electrical input for detachably coupling with an external cable or information system device and for transmitting and receiving information-containing electrical signals over such input, and a fiber optic connector adapted for coupling with an external optical fiber for transmitting and receiving an optical signal; an electro-optic subassembly coupled to the information containing electrical signal and converting it to and/or from a modulated optical signal corresponding to the electrical signal; a memory disposed in said housing for storing an encrypted identifier; and a communication interface disposed in said housing for electrically transferring the data to an external device when the module is authenticated using the encrypted identifier, to enable operation of the module.
摘要:
A system for the generation of electrical power from sunlight includes a solar cell assembly with at least two sets of solar cells, each of these sets being adapted to a set-specific light frequency spectrum so as to convert light having said set-specific frequency spectrum into electrical energy with an optimized energy conversion efficiency. The system is arranged to respond to changes in the frequency spectrum of the sunlight, for example, in accordance with the time of the day, by causing the sunlight to selectively impinge on one or another of the different sets of solar cells. Thus, an enhanced energy conversion efficiency of the system is obtained.
