Abstract: PURPOSE:To shorten the test time by generating a pattern within a test cycle after execution of block write function for example. CONSTITUTION:A selection circuit 3 selects the side of ALPG 1 and the pattern thereof is written, as a background pattern, into a device to be measured and an expectation memory 2.

Abstract: PURPOSE:To prevent a sort of discomfort to be given to a measuring person by switch in display, by displaying a virtual temperature rising ideally after the start of the temperature inspection to perform a switch in display continuously from the virtual temperature to an estimated body heat value. CONSTITUTION:With a power source switch 7 ON, a CPU3 actuates a temperature sensor 1 by ON operation of of a power source switch 7 to memorize temperature information being sent constantly through an A/D converter 2 into a memory 4. Furthermore, with the start of temperature inspection by a measuring person, an output temperature of the sensor 1 rises and when this start of the temperature inspection is detected, a virtual temperature rising at a specified rising rate is displayed 5 from a preset specified temperature (e.g. 30 deg.C) regardless of measured temperature. In addition, the CPU3 analyzes the measured temperature information and calculates an estimated body heat value based on a fixed expression. When the estimated body heat value coincides with the virtual temperature, it performs a control for display 5 of a forecast body heat value or the like. As a difference reaches a fixed temperature (e.g. within 0.5 deg.C) between the estimated value and an actually measured value, a buzzer 6 is actuated to inform to the effect. With a switch OFF, the power source 8 breaks to complete the measurement.

Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To remove various kinds of noise components, to prevent the power of optical signal from being attenuated and to attain long-distance repetition even at the time of fault by only selecting a main signal at a transmitter. SOLUTION: When optical signals from both an optical transmission line 31a for incoming access and an optical transmission line 28a for bypass are inputted to a transmitter 26a, only an optical signal 32d coming through the optical transmission line 31a for incoming access having more optical signal power is reproduced and repeated. This signal 32d is impressed to an optical transmission line 21b as an optical signal 32e, reproduced, repeated at a receiver 24b, impressed to a beam splitting part 27b later, branched to optical signals 32f and 32g here and impressed to an optical transmission line 28b for bypass and a node 32b.  When any fault occurs at a node 23a, there is no input of optical signal from the optical transmission line 31a to the transmitter 26a, the transmitter 26a reproduces and repeats an optical signal 32b from the optical transmission line 28a for bypass, and it is transmitted to the optical transmission line 21b as an optical signal 32e. Thus, long-distance repetition is possible even at the time of fault.
