Title: Radioactive ray measuring instrument
Inventor: SATO HIROO
IPC: G01T1/185
Filed: 1994-11-08
Abstract: PURPOSE: To perform measurement without requiring an ion precipitator by measuring only radon/thoron as a parent nuclide without being affected by a daughter nuclide. CONSTITUTION: A face-shaped one-side electrode 42 is laid out near an α-ray incidence window 34 of an ionization box 28 and the other-side electrode 44 is laid out away from it. A high voltage is applied to radon daughter nuclide and thoron daughter nuclide with polarities to be captured by the other-side electrode 44 between both electrodes 42 and 44. The α rays from radon and thoron advance inside the ionization box 28 from the α-ray incidence window 34 and are detected. The α rays from the radon daughter nuclide and thoron daughter nuclide captured by the other-side electrode 44 do not reach the α-ray incidence window 34 and cannot be detected. Even if another ion enters a gas introduction chamber 30, it does not affect measurement unless it is radioactive, thus eliminating the need for an ion recipitator.

IPC: H03K3/02
Filed: 1984-12-28
Abstract: PURPOSE:To attain threshold switching setting with high accuracy by using two transistors (TRs) having an identical characteristic to switch the threshold value and controlling the setting of threshold value with high accuracy by a resistor and a reference power supply independently of the saturated voltage of the TRs. CONSTITUTION:An input voltage is applied to a non-inverting input of a comparator OP1, the comparator OP1 compares the input voltage VIN with an inverting input voltage Vth and outputs the result as a voltage Vout. Then a current of an input TRQ3 of a current mirror comprising the TRs Q3, Q4 connected to the output is controlled to allow the output TRQ4 to control a TRQ0 in the threshold switching TRs Q1, Q0 to actuate the TRQ1 for the threshold value change. It is possible to decrease the setting error from nearly 10% of a conventional threshold value switching using a low reference voltage into an error of 1% or below by providing the paired TRs for the threshold value switching. Thus, the comparison with high accuracy is attained even when the reference voltage is low without being affected by the saturated voltage of the TRs.

IPC: G01C3/06
Filed: 1993-10-07
Abstract: PURPOSE:To reduce power consumption on range finding by extending the synchronization of continuous range finding when a signal level is less than a certain level longer than that when the signal level is equal to or more than the certain level in the case of the continuous range-finding mode by judging the level of the signal received by a light reception means. CONSTITUTION:A light projection element 2 is driven via a light projection control means 1 and infrared rays are projected toward a range-finding target 4. Then, the reflection light of the target 4 is received by a PSD 6, the output is read by a range-finding operation means 7, and then the distance from the output of the means 7 to the target 4 is calculated. In the case of continuous range finding, a signal level is judged by a signal level comparison means 8 after waiting for a specific amount of time and then a measurement operation is initiated after waiting for a specific amount of time when the signal level is less than a specific level. Range finding is performed continuously when the signal level is equal to or more than the specific level, thus reducing the power consumption on continuous range finding and hence preventing the deterioration of the element 2.
