Abstract: PURPOSE:To control precisely an operating condition for a furnace by scanning and measuring the temp. on one end side of a tubular object and obtaining the information on the measured temp. corresponding to the temp. measuring position by using the size of the tubular object in the stage of measurement and the value indicating the installation condition of a radiation thermometer. CONSTITUTION:A radiation thermometer 4 scans a visual field angle range theta for measurement and measures the temp. in the range of the outside and inside surfaces of a steel pipe 1 in a furnace 2 corresponding to the angle theta. The detection signal from the thermometer 4 is converted to a temp. signal in a temp. measuring signal circuit 11 and the momentary scanning angle + or -thetaa of the thermometer 4 is determined in a scanning angle signal circuit 12. The distance L1 between the end part 6 on the temp. measuring side of the steel pipe 1 in the furnace 2 and the inside surface on the furnace side wall as well as the outside diameter D and wall thickness (t) of the pipe 1 are set and inputted in a setter 13.

Abstract: PURPOSE:To economize a test equipment and to make the weight light by allowing an exchange to use a multi-frequency signal reception circuit provided for exchange processing in common so as to receive and analyze a multi- frequency signal arrived from a multi-frequency signal line being a test object. CONSTITUTION:A multi-frequency signal reception circuit 300 receives a multi- frequency signal arrived from a multi-frequency signal line 200 to identify a code represented by a multi-frequency signal. A branch means 400 branches the result of identification of the multi-frequency signal and outputs the result externally. A test equipment 500 receives the result of identification of the multi-frequency signal outputted from the multi-frequency signal reception circuit 300 by the branch means 400 and discriminates the signal as the result of test of the multi-frequency signal arrived from the multi-frequency signal line 200. Thus, the reception and analysis of the multi-frequency signal reached from the multi-frequency signal line being a test object are implemented by using the multi-frequency signal reception circuit provided for exchange processing in common. Thus, the test equipment testing the multi-frequency signal reached from the multi-frequency signal line is economized and the weight is made light.

Abstract: PURPOSE:To reduce the number of communication lines, by detecting the nobusy state of the other equipment by one equipment to transmit data from one equipment and by detecting data transfer from the other equipment by one equipment to receive transfer data, in the system simultaneous two-way data transfer is not required. CONSTITUTION:When equipment A transmits data to equipment B, equipment A detects whether input signal AI from communication line W is high-level or not, and equipment A waits until signal AI becomes high-level if signal AI is low-level, that is, equipment B is busy. When signal AI becomes high-level, equipment A transmits output signal AO through transistor inverter 5, and this signal is received as input signal BI of equipment B. Equipment B decides whether signal AO is the data transmission request to equipment B or not after the delay time after receiving of signal AO; and if it is the transmission request, output signal BO is transmitted from output terminal 4 of equipment B through inverter 6; and if it is not the transmission request, output terminal 4 is made high-potential to indicate that equipment B is busy, and output terminal 4 is made low-potential after the processing in equipment B.

Abstract: PROBLEM TO BE SOLVED: To prevent discharge of white smoke even if an idling state lasts for a long time. SOLUTION: In this diesel engine, steps 101, 103, 104 are repeted as long as an idling state continues, and continuing time T gradually approaches a threshold value Xh. When the continuing time T of the idling state exceeds the threshold value Xh, (the step 104, Yes), rotational speed of an output shaft of the diesel engine is increased (step 105). A fuel amount injected into a combustion chamber is increased, so that the temperature in the combustion chamber is raised. It is thus possible to prevent generation of unburned HC.
