Title: Radiation detecting circuit
Inventor: KISHI HARUO
IPC: G01T1/17
Filed: 1988-02-29
Abstract: PURPOSE:To detect a pile-up state by integrating the difference between an input signal and its delayed signal and detecting whether the integral value is large or small. CONSTITUTION:The output signal of a radiation detector is inputted to a subtracting circuit 2 directly and also inputted to the circuit 2 through a delay circuit 1. The circuit 2 calculates the difference between said delayed signal and direct signal and its output value is integrated by an integration circuit 3 and then supplied to a pulse height discriminator 4 for pulse height discrimina tion. Namely, when a signal (d) and then a signal (e) are piled up, the composite signal is (f). Here, the difference between the delayed signal and direct signal is integrated and then the integral value corresponds to the area of the hatched part obtained by subtracting a part (b)-(c) from a part (a)-(b). The value is smaller than that when no pile-up state is not entered, so the pile-up state can be detected by discriminating the pulse height.

Title: Wind direction and speed measuring instrument
Inventor: FURUSAWA KAORU
IPC: G01P5/02
Filed: 1987-03-03
Abstract: PURPOSE:To accurately measure the direction and speed of a wind in a breeze range by supporting a wind receiving body so that it swings freely in all directions and supporting it at a natural attitude vertically below a support point. CONSTITUTION:When the wind receiving body 1 receives a wind W, the wind receiving body 1 moves in the opposite direction from the wind W to a position proportional to the wind. Consequently, a rod body 2 slants around a support mechanism 7 as a fulcrum. This inclination of said rod body 2 allows a motion structure 803 to move in the space C between stationary structures 801 and 802 as shown by an arrow D, and consequently the confrontation area between a stationary electrode and a motion electrode varies, so that the variable electrostatic capacity formed of them varies in correspondence to the inclination of the said rod body 2. Oscillation circuits 21-24 output oscillation signals of frequency corresponding to the value of said electrostatic capacity. A processor processes those oscillation signals to compute the wind direction and wind speed.
