IPC: H01H47/00
Filed: 1994-07-26
Abstract: PURPOSE:To start the relay motion accurately with the initial condition of a circuit when a signal contact is put in the normal operating condition after recovery of the failure by using the fact that the electric charges on a capacitor are discharged rapidly the moment the signal contact is opened in the event of a failure. CONSTITUTION:A signal contact (a) is closed in response to an input signal so that the base current flows to an NPN transistor Q via a series circuitry of a capacitor C and resistance R1, and the transistor Q is turned on and also a relay Ry is actuated along with alarm emission from an alarm device. In this relay drive circuit, a diode D3 is connected parallel with a series circuitry consisting of a resistance R2 interposed between the base and emitter of the transistor Q and the abovementioned resistance R1 in series connection with the capacitor C.

IPC: G01R33/48
Filed: 1990-07-03
Abstract: PURPOSE: To make it possible to analyze the linear shapes as well upon selectively measuring the solid samples for volumes, by changing magnetizing only one slice of a sample to the 90 deg.-inclined transversal magnetization at the first time interval, entering the volume-selective gradient magnetic field pulses at the second time interval, irradiating the high-frequency pulses at the third time interval, returning the multipolar state back to the transversal magnetization at the fourth time interval, and reading out the results as a signal. CONSTITUTION: A slice of sample is selected by using the pulse system 10 consisting of the first 90 deg. pulse 11 and spin-lock pulse 12 and the second 90 deg. pulse 13, being irradiated toward the z-direction while the gradient magnetic field pulse 14 exists. After lapsing a time interval (tau-1) determined by the pulse system 10, the two phase gradient magnetic field pulses 15, 16 are then inputted toward the x- or y-direction at the second time interval (tau-2). Then, the 90 deg. high-frequency pulse 17 at the beginning and the 45 deg. high-frequency pulse 18 at the ending, both at the third time interval (tau-3), are irradiated onto the sample, respectively. At the fourth time interval (tau-4) followed by the foregoing, the phase gradient magnetic field pulses 15, 16 can again be disconnected without losing the magnetization via the early attenuation.
