Abstract: PROBLEM TO BE SOLVED: To reduce the weight and size of a dust collector mounted on a radiation monitoring car that collects dust samples from the surrounding area of a radioactive substance treating facility. SOLUTION: The engine 30 of a radiation monitoring car is utilized as an air sucking source. The air introduced from an intake port is passed through a filter paper 14 and dust contained in the air adheres to the paper 14. The air is passed through an air filter 32 via a flowmeter 36 having a flow regulating function. Another air is passed through the filter 32 via an auxiliary air sucking path 37. A flow regulating section 40 adjusts the flow rate of the air in accordance with the number of revolutions of the engine 30 as necessary.

Abstract: PURPOSE:To automatically set an optimum smoothing period according to the fluctuation of dose rate by determining an integrating width from a distributed value arithmetically operated with a plurality of measured values including the present measured value at this point of time as elements, and integrating the measured values in the integrating width. CONSTITUTION:The detection signal of a radiation detector 10 is stored 12 in time series to regularly keep a counting rate (n0 shows the rate at present, n1, n2... show rates before this) within a fixed time from the present time, and it is outputted to an integrating part 14 and an adding part 16. The adding part 16 carries out addition in each period for distributed value operation, and the added value is stored 18 timewise. An integrating width judging part 20 sets thresholds N0+KN1 , N0-KN0 with an added value N0 as standard, judges the added value first exceeding either one of the thresholds back from this point of time, and outputs the period to the added value as an integrating width 100 to the integrating part 14. The integrating part 14 integrates all the counting rates in the width 100, and the result is averaged by a display arithmetic part 22. Further, the arithmetic part 22 multiplies the average value by a prescribed coefficient to calculate the dose ratio, and displays 23 it as measured value.

Abstract: PURPOSE:To improve statistic accuracy with the lapse of time and to obtain a count value whose indication value is not sharply changed by displaying a counting rate value obtained by dividing an integrated value obtained by integrating values by an adder by the time required from detection start up to the current time. CONSTITUTION:When a radiant ray is injected into a detector 12, low pressure vapor (alcohol steam, etc.) is ionized, electric discharge is generated and a discharge current is instantaneously allowed to flow and A/D converted into a digital signal 100. The signal 100 is amplified by an amplifier 14 and the amplified digital signal 101 is counted by a counter 16. A sampling circuit 20 outputs a timing pulse 102 in each previously set time, the count value 103 of the counted signal 101 is outputted to an adder 18 in each timing and the counter 16 is reset by the count signal 103. The adder 18 integrates the count value 103 successively outputted from the counter 16 and outputs the total number 105 of counts from the count starting point up to the current point to a divider 24. The divider 24 calculates the count rate value, which is displayed on a display device 26.

Abstract: PURPOSE:To prevent noise from being generated, by setting the duty of switching pulse to be less than 50 %, and by inserting resistors into an input circuit to switching transistors. CONSTITUTION:The input ends 10, 12 of a high-tension switching power source is supplied with square switching pulses in opposite phase. The input ends 10, 12 are respectively connected to the gate channels 18a, 20a of switching transistors (Tr) 18, 20 via resistors 14, 16. The drain channels 18c, 20c of the Tr 18, 20 are respectively connected to the end sections 26a, 26b of the primary winding of a step-up transformer 26 whose center tap 26c is connected to a DC power source 28. In this case, the frequency of the current flowing into the primary winding of the step-up transformer 26 is determined to coincide with the resonance frequency of a circuit including the winding. Besides, the duty is set to be less than 50%, and so current flowing to the primary winding have a waveform approximate to a sine wave.

Abstract: PROBLEM TO BE SOLVED: To provide a personal dosimeter that holds a coin-type battery without fail.
SOLUTION: A storage part 26 contains a battery. When the battery is inserted into the storage part 26, the battery is held by a pair of contact members 44, 46 from the right and left sides. Consequently, conduction to a positive electrode is also established. A negative-electrode contact member 50 contacts the lower side of the battery in a battery set state, and thereby conduction to a negative electrode is established. Since the contact member 50 contacts the battery from the lower side by two or more elastic pieces 52, the battery can be prevented from vertical backlashes. That is, the battery can be held stably, in both the horizontal and the vertical directions.

解决方案：存储部分26包含电池。 当电池被插入存储部分26中时，电池由一对接触件44,46从右侧和左侧保持。 因此，也建立了对正极的导通。 负极接触构件50在电池组置状态下接触电池的下侧，从而建立到负极的导通。 由于接触构件50从下侧通过两个或更多个弹性片52接触电池，所以可以防止电池垂直的背隙。 也就是说，可以在水平和垂直方向上稳定地保持电池。 版权所有（C）2011，JPO＆INPIT
