IPC: G01N3/32
Filed: 2000-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a materials testing machine, where the transmission efficiency of the power of a motor is satisfactory and a drive mechanism can be controlled always precisely at low cost and without generating backlashes. SOLUTION: As the drive mechanism 2, by which one from between a pair of gripping implements 3a, 3b used to grip a work W1 under test and a work W2 under test is brought close/separated with reference to the other, a mechanism which is composed of a ball screw 21a and the motor 22 which turns its screw shaft 211a is adopted. The output shaft 22a of the motor 22 is coupled directly to the screw shaft 211a. As compared with a conventional materials testing machine, which transmits the power of a motor by a belt transmission mechanism using a timing belt, loss due to the existence of the belt transmission mechanism is eliminated, the adjusting operation of the tension of its belt is eliminated, and the position detection error of the gripping implement 3a, caused by the backlash due to a gap in the engagement part of the timing belt to a pulley, is eliminated.

Title: Method for melting treatment of waste
Inventor: OSANO HIDEMI
IPC: F23G5/24
Filed: 2000-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a waste melting furnace which dispenses with auxiliary fuels, such as coke, by directly melting the wastes without incineration. SOLUTION: The wastes inserted into the furnace are subjected to preheating, drying and thermal decomposition by air or oxygen enriched air which has been blown to the lower part of the furnace to obtain thermal decomposition residue. Meanwhile, melt, which has been collected in advance in a collecting portion formed in the furnace floor, is subjected to induction heating, and with the resultant heat from the melt, the thermal decomposition residue is subjected to melting treatment. Thus no such expensive expendable as a graphite electrode is required. Also, no fuel is required because heat resulted from burning the wastes can be converted to electric energy so as to be used as an induction heating power source, thereby remarkably reducing the treating costs.  Further, as heating temperature can be readily controlled by changing applied electric power, slag of stable quality can be produced.
