    • A steam turbine governor system including two governor electronic sections for producing a turbine valve opening command to control the opening of steam valves thereby controlling a flow of steam into the turbine in dependence upon a difference between an actual turbine speed and a target turbine speed and a target turbine load. One governor electronic sections is actually used for controlling the opening of the steam valves, while the other governor electronic section is a stand-by. A first value relating to the turbine speed acceleration rate based on the turbine valve opening command produced by each of the governor electronic sections is obtained so that the first values are obtained parallelly and independently of each other in the two governor electronic sections. Turbine valve opening commands produced by the respective governor electronic sections are compared with each other and produce a start signal when the difference between them exceeds a predetermined level. A second value relating to the turbine speed acceleration rate based on the actual turbine speed is obtained, and a majority logic is applied to the first values obtained by the two governor electronic sections and the second value. An abnormality of any of the governor electronic sections is obtained based on the result of application of the majority logic.

    • An apparatus comprises a cruise control section to control an engine output according to an acceleration/deceleration demand set according to an acceleration/deceleration demand from a driver or a cruise control demand set to match an actual vehicle speed to a preset vehicle speed or to match a vehicle distance relative to a forward-going vehicle to a preset value, whichever demand is greater, a speed shift control section to shift gears and to control the engine output, and a switch control section to switch the cruise control section and speed shift control section according to their priority order. The speed shift control section, upon being switched by the switching control section to the cruise control section after the completion of the shift changing, returns the engine output back to that previous switching state based on the cruise control section.

    • The microcomputer includes a CPU, a ROM, an OSD circuit, a wait signal generation circuit and a bus switch circuit. The ROM stores a program to be executed by the CPU and display data to be on-screen displayed on a display. The OSD circuit reads the display data stored in the ROM and outputs the read data to the display. The wait signal generation circuit generates a wait signal having a first level of a first time period and a second level of a second time period repeated alternately. The wait signal generation circuit determines the length of the first time period according to the amount of the display data to be read from the ROM to the OSD circuit. The bus switch circuit establishes a bus between the OSD circuit and the ROM when the wait signal is in the first level, and establishes a bus between the CPU and the ROM when the wait signal is in the second level.

    • A method of controlling combustion in a furnace of a boiler or the like having a burner for a main combustion and a burner for a reducing combustion in order to effect combustion for furnace denitrification. The method comprises the steps of: estimating the NO.sub.x generation amount from data on a flame formed by the main combustion; estimating the reducing agent generation amount from data on a flame formed by the reducing combustion; and controlling the flow rates of fuel and air supplied for the main and reducing combustions so that the amount of NO.sub.x emission as the difference between the NO.sub.x generation amount and the reducing agent generation amount is below a specified value. In practice, each of the NO.sub.x generation amount and the reducing agent generation amount is estimated from the flame pattern, the flame volume, the distance between the outlet of the burner concerned and the root of the flame concerned, etc., thereby to distributively control the flow rates of fuel and air supplied to each of the main combustion burner and the reducing combustion burner so that the amount of NO.sub.x emission is below a specified value.
