Title: Measuring apparatus of radiation temperature based on two spectral radiation detection signals
Inventor: TANAKA TOMIO
IPC: G01J5/00
Filed: 1991-06-07
Abstract: PURPOSE:To obtain a measuring apparatus of radiation temperature which enables execution of measurement in an area of lower temperature or an area of a smaller target size than a usual radiation and, in addition, which can be applied also to an object of which the emissivity fluctuates.

Patent JP-S6318416-A (JP)
Title: Power source stabilizing device
Inventor: KONISHI TAKAFUMI
IPC: H02M1/08
Filed: 1986-07-10
Abstract: PURPOSE:To minimize the drift of a voltage to temperature fluctuation, by providing a diode for temperature characteristic correction in series in addition to a seference diode in a DC reference voltage stabilizing circuit. CONSTITUTION:A DC reference voltage stabilizing circuit 16 is composed of a seference diode 14 and diode 15 for temperature characteristic correction. Fluctuation of the DC bias voltage of saw-tooth-like wave signals for thyristor conducting angle control caused by the variation of the DC amplification factor hfe of an error amplifying transistor (Tr) 13, is corrected by the temperature coefficient of the diode 15 and VBE of a Tr 12 for inversion. In other words, when the temperature becomes low, the collector voltage rises and the saw- tooth-like wave DC bias voltage of the base of the Tr 12 rises and causes the B2 voltage to increase, since the hfe of the Tr 13 decreases. However, since the temperature coefficients of the VBE of the Tr 12 and VF of the diode 14 are negative, a DC seference voltage rises and causes the B2 voltage to drop at a low temperature. The same can be said in the case of a high temperature. Therefore, the temperature drift of a supply voltage control circuit can be minimized.

Then, the waveform data is inputted to a main processing section 40 and a wave form undergoes a polygonal line plotting with a feature quantity-extracting section 50 to be converted into a feature quantity vector. Subsequently, the feature quantity vector is sorted automatically with an estimating section 60 to obtain the intensity of a sorting waveform for estimation of grain size information. Finally, an estimation of the grain size information of the granule is performed according to an estimation rule to be obtained from the sorting waveform intensity.

Abstract: PROBLEM TO BE SOLVED: To reduce a cost by switching power supply voltage applied from a voltage regulator circuit on the semiconductor integrated circuit on an on- board into voltage higher than voltage at the time of normal use, in the case of an input voltage range which is not used normally. SOLUTION: A device is provided with a voltage regulator circuit 104 on an on-board, and a voltage monitoring circuit 500 for detecting primary input voltage (VIGN) of the voltage regulator circuit 104. The voltage VIGN of the voltage regulator circuit 104 is distinguished into an input voltage range in which an on-vehicle electronic unit is used normally and an input voltage range in which it is not used normally by the voltage monitoring circuit 500. In the case where the voltage VIGN is in the input voltage range in which it is not used normally, power supply voltage applied from the voltage regulator circuit 104 on the semiconductor integrated circuit on an on-board is switched into voltage which is higher than voltage at the time of normally using. It is thus possible to switch power supply voltage automatically, and burn-in-test is carried out.
