Abstract: PURPOSE: To accurately confirm the function of an ATC by controlling the amplitude of the alternating wave from an alternating-wave generator circuit in a feedback connection with an arithmetic unit in order to form a desired pseudosignal corresponding to the output characteristic of a rotary generator or the like.  
     CONSTITUTION: With setting data added to a latch circuit 41 in a sine-wave generator circuit 31 from an arithmetic unit of a computer or the like through a bus line 30, a counting according to the setting data is performed by a voltage/frequency converter 43 and a counter 44 according to the output of a digital/analog converter 42. The count, being an address, causes a memory element 45 to be accessed, and the feedback of the count of the counter 44 to the arithmetic unit through a frequency setting feedback circuit 33 permits a sine-wave of a desired frequency to be accurately generated independently of noises or the like of the line 30. The amplitude of the sine-wave is controlled in a sine-wave amplitude control circuit 32, and the wave becomes a pseudosignal corresponding to the output characteristic of a rotary generator for the ATC speed instruction. The constitution, which also provides a simulation of a wheel diameter change due to abrasion, permits the function of the ATC to be accurately confirmed.

Filed: 1993-03-04
Abstract: PURPOSE:To suppress the generation of outer flame and promote the generation of inner flame in the formation of a diamond with an inner flame generated by burning a combustible gas containing a carbon compound together with oxygen or hydrogen gas and to enable the efficient growth of diamond by covering the inner flame with an inert gas. CONSTITUTION:The expansion of an inner flame 2 is increased more than 4 times by covering the inner flame 2 with an inert gas 7. Simple gas is used in some cases as the inert gas, however, the use of a mixed gas is suitable for controlling the radical concentration. The mixed gas to be used in the process is a combination of a gas having high density with a gas having a low density and the expansion of the inner flame 2 and the radical concentration of the reaction gas in the inner flame 2 are controlled by varying the mixing ratio of the mixed gas. A pretreated substrate 9 is attached to a substrate holder 10 and the substrate temperature is finely adjusted with a water-cooled tube 12. The radical concentration in the inner flame 2 is adjusted to a level suitable for the growth of a diamond by using an inert gas curtain 6 flowing through an inert gas introducing pipe 8 placed at the outside of the torch 4. The process can be carried out even in a magnetic field.
