Title: Pulse width control circuit
Inventor: FUKUHARA YOSHIHIKO
IPC: H03K7/08
Filed: 1980-06-09
Abstract: PURPOSE:To simplify the constitution of a pulse width control circuit, by using a voltage comparator having one input terminal of a polarity and a plurality of input terminals of another polarity. CONSTITUTION:A saw tooth wave is inputted to a negative input terminal 40 from an oscillator, and an output of an error amplifier and a DC voltage to set the maximum pulse width are respectively given to positive input terminals 41, 42. If the potential of the terminal 41 is higher than that of the terminal 40, a transistor (TR) 31 is interrupted, and if the potential of the terminal 42 is higher than that of the terminal 40, a TR30 is conductive and a high potential signal is outputted at an output terminal 11. Inversely, if the potential of the terminal 42 is lower, a low potential signal is outputted. Thus, the terminals 41, 42 have a voltage comparison function to the terminal 40, the logical product of compared output is taken to an applied signal, and the number of components for the control circuit can be reduced.

Abstract: PURPOSE:To reduce the term and cost required for the development and design of a molded item by a method wherein strain due to thermal stress is calculated by utilizing the temperature distribution of the molded item at the point of time, at which the connection between the melt phases is cut, obtained from the temperature change of molding material during molding process and, after that, the formal strain of the molded item is calculated from the displacement due to said strain due to thermal stress. CONSTITUTION:The points of time, at which interior maximum temperatures at the respective parts of a molded item reach the flow stop temperature, are calculated by utilizing the flow stop temperature stored in an input data store 2 and the temperature information at respective time steps since the start of molding, which is stored in a store 4 of flow during pouring and in a store 6 of flow during dwelling. Next, the points of time, at which molding shrinkages at the respective parts of the molded item start, are calculated. Both the calculated results are outputted to a store 10. The temperature information and pressure distribution at the molding shrinkage starting time, which is stored in the store 10, are obtained from the store 4 or 6 and outputted respectively to a store 12 and a store 14. By utilizing the temperature information in the store 12, the pressure information in the store 14, the pressure, specific volume and temperature data, which are stored in the input data store 2, the temperatures at the molding shrinkage starting time are corrected. The displacement of the molded item is calculated through the analysis of strain due to thermal stress, which is performed by adopting the difference between said corrected temperature and room temperature as heat load condition.
