An interrupt signal EMG is put out to a microprocessorwhen a thermal monitordetects that a package temperature exceeds a reference. The microprocessor then increases a frequency division value N stored in a frequency division value registerof a clock mechanism. An inputted clock signal MCK is divided by N to generate a system clock signal SCK. Therefore, the frequency of system clock signal SCK decreases when N increases. Consequently, electricity consumption of each function modulei decreases and the package temperature is reduced.

Temperature controlled semiconductor circuit

A work management system has input means having a function of inputting coordinate information from the surface of a panel, output means having a function of projecting electronic information onto the panel, and data processing means for executing a predetermined processing, e.g., preparation and input processing of a form, a chart or a drawing, retrieval, editing, totalization, etc., by establishing a correspondence between the information projected on the panel by using the output means and the coordinate information input from the input means. The data processing means displays a list of registered items to be designated in a window for selection of one of the items, whereas, when coordinate information is input from two points for an entry column for time setting, the data processing means draws a bar between the two points. Control information which is conformable to working hours of equipment at a work site, e.g., temporary lighting equipment, is generated by a preliminary arrangement system employing an electronic board, and the control information is transferred to a supervisory control system to effect supervisory control of the equipment on the basis of the control information.
