Title: Method of constructing a metal diagram for a material that acts under three-dimensional stress field conditions.
Inventor: SHELOMOV MYKOLA A
IPC: C21D7/00
Filed: 2005-10-19
Abstract: The invention relates to a method which involves the use a series of test pieces with special grooves having different sensitivities to fragile destruction, said sensitivity value depending almost solely on the radius (r<SUB>1</SUB>) at the point of origin of the groove (the other parameters of the test pieces in the series being constant), and which is intended for the experimental calculation of the experimental data for steel A-36 and two M. Schnadt diagrams, namely a pessimistic diagram and an optimistic diagram (Figure 5,6 and Table 2), which are obtained for the first time. The purpose of the invention is to produce experimentally the values of parameters srfr and p for each structural material, which have remained unknown for three hundred years. In order to obtain experimental results of good quality, the manufacturing process must be performed with greater accuracy and greater quality of material. At present, without the above-mentioned information, it is impossible to correc t modern software programs that cannot correctly evaluate the strength of materials and structures acting under three-dimensional stress conditions, which poses a serious risk to individuals and humanity as a whole. ?? ?? ?? ??.

Inventor: CHEN HSI-HUNGUNG
IPC: H02J1/00
Filed: 1993-11-03
Abstract: A CIRCUIT FOR SYNCHRONIZING AN OPERATING CLOCK OF A SWITCHING POWER-SUPPLY (SPS) SYSTEM IS PROVIDED. THE SPS HAS AN OSCILLATOR, A PRIMARY CONTROL CIRCUIT, A SECONDARY VOLTAGE GENERATION CIRCUIT, A FEEDBACK CONTROL CIRCUIT. THE OSCILLATOR OUTPUTS AN OSCILLATION SIGNAL TO THE PRIMARY CONTROL CIRCUIT. THE FEEDBACK CONTROL CIRCUIT, IN RESPONSE TO A DIRECT CURRENT (DC) VOLTAGE FROM THE SECONDARY VOLTAGE GENERATION CIRCUIT, GENERATES A DC FEEDBACK VOLTAGE SIGNAL. THE SYNCHRONIZATION CIRCUIT COMPRISES AN ISOLATION DEVICE, A SIGNAL SEPARATION CIRCUIT AND A TRIANGLE-WAVE GENERATION CIRCUIT. THE ISOLATION MEANS HAS AN INPUT TERMINAL AND AN OUTPUT TERMINAL. THE INPUT TREMINAL RECEIVES A HORIZONTAL SYNCHRONIZATION SIGNAL AND THE DC FEEDBACK VOLTAGE SIGNAL. A MIXED SIGNAL IS GENERATED AT THE OUTPUT TERMINAL AS A RESULT OF AMPLITUDE-MODULATING THE DC FEEDBACK VOLTAGE SIGNAL BY THE HORIZONTAL SYNCHRONIZATION SIGNAL. THE INPUT TERMINAL IS VOLTAGE-ISOLATED FROM SAID OUTPUT TERMINAL. THE SIGNAL SEPARATION CIRCUIT GENERATES A SYNCHRONIZATION SIGNAL BY FILTERING OUT THE COMPONENT OF THE DC FEEDBACK VOLTAGE SIGNAL OF THE MIXED SIGNAL. THE TRIANGLE-WAVE GENERATION CIRCUIT HAS AN OUTPUT TERMINAL AND AN INPUT TERMINAL. THE INPUT TERMINAL RECEIVES THE SYNCHRONIZATION SIGNAL AND THE OUTPUT TERMINAL GENERATES THE OPERATING CLOCK OF TRIANGLE-LIKE SHAPE, WHICH IS SYNCHRONIZED WITH THE HORIZONTAL SYNCHRONIZATION SIGNAL, TO THE OSCILLATOR.
