Abstract:

A furnace for growing a semiconductor crystal includes an elongated tubular chamber encased within a cylindrical jacket. The furnace is divided into a plurality of zones with each zone having a corresponding insulation block for preventing heat loss from the chamber and to absorb external vibrations. The chamber is heated by sets of heater elements fixed thereto. Each set of heater elements is controlled by a corresponding processing means which supplies needed power thereto for generating the desired temperature in that zone. To draw heat from a particular area, an annular shunt disc may be interposed concentrically between the chamber and the jacket for providing a radial path for heat to flow from the chamber to the environment through the jacket. Because of its sound construction and the requirement of only minimal power, this furnace is particularly well adapted to operate on Earth, and in a micro-gravity environment and withstand launches to and from space.

Abstract:

A frame equipped with a fork on the front thereof carries either wheels or runners to engage the surface, and has a transversely extending seat mounted thereon that projects from both sides of the frame. A mast is mounted on the frame forwardly of the fork, and has a rearwardly-extending boom pivotally connected thereto, the mast and the boom carrying a sail. A hand-hold is formed on the boom, whereby a rider seated on the transversely extending seat can manipulate the sail to operate the bicycle, the seat facilitating side-to-side shifting of the rider's weight during operation. A closed loop handle on the fork makes one-hand steering of the bicycle easy to obtain.
