Thermal Conductivities

Measurements have been made by several observers on the thermal conductivities of metals and alloys up to high temperatures. Heat losses to the surroundings become large at high temperatures, hence the guard tube method, which to a great extent eliminates these losses, has been popular for work at these temperatures. This method was described and used by Berget in 1888, and later by Wilkes. These observers measured the rate of heat flow by a calorimetric method, which is not suitable for work at high temperatures. Honda and Simidu, using an internal heating coil, determined the heat flow from the energy input and were able to obtain results for nickel and steel to over 800°C. More recently, Schofield, using the guard tube method with an internal heating coil, has obtained results up to a maximum temperature of 700°C. with five metals. The present work was undertaken with a view to continuing the work of Professor C. H. Lees on the effect of temperatures between —160°C. and 15°C. on the thermal conductivities of nine metals and six alloys.

Hardware And Software System

If the links which can be used as the components of a robot are organized in a manner of ""modularized units"" equipped with an actuator, a sensory device, and even a servo-mechanism, respectively, many kinds of robots can be easily constructed and their flexibility will be greatly improved. For this purpose, we developed a modularized link unit comprised of a DC servo motor, a position sensor, and a reduction gear set. This unit has a number of characteristics such as having large torque and small backlash, making the direction of the robot hand independent of its position, and so on. Using these units, we constructed a ""personal robot"" and developed its control system. In this paper, we introduce the composition and characteristics of our link unit, and illustrate the hardware and software system of a robot made from the modularized link units in this study.
