Title: Overload preventing circuit for x-ray tube device
Inventor: ASAI ITARU
IPC: H05G1/54
Filed: 1988-04-04
Abstract: PURPOSE:To accurately take hold of a stored heat energy on any radiating condition so as to enable suitable overcurrent protection by simulating the thermal behavior of an X-ray tube device by means of an overload protective circuit. CONSTITUTION:After detecting a tube voltage V and a tube current Ib, a power calculating unit 24 determines the multiplied value thereof. An integrating circuit 25, where a charge time constant and a discharge time constant simulate a thermal time constant of an X-ray tube device, converts the multipled value into a real value signal of a heat unit(HU) value corresponding to heat energy stored in the tube device. A judging circuit 26 compares the signal with an upper limit value setting signal of a heat capacity stored in the tube device so as to output a trip signal. Reception of radiation for a short time enables simulation one by one of changes at every moment in the heat energy stored in the tube device so that the output of the trip signal stops the tube current when the HU value corresponding to the stored heat energy exceeds the HU upper limit value corresponding to the heat capacity stored in the tube device. This can prevent an overload in the tube device with accuracy.

Abstract: PROBLEM TO BE SOLVED: To simply and rapidly measure the particle size of fine particles in a dispersion by supplying a fine particle dispersion to one surface of a microporous membrane having a predetermined min. pare size and observing the fine particles pentrating into the other surface thereof. SOLUTION: An asymmetric microporous membrane 10 is held between respective outside and inside supports 12, 14. The support 12 has opening parts 12a as the supply surface of the sample liquid (fine particle dispersion) 16 on the large pore size side of the membrane 10 and the support 14 has opening parts 14a as the penetration state observation surface of fine particles on the small pore size side of the membrane 10. The membrane 10 has a pore size distribution changed in pore size in the membrane thickness direction and is the asymmetric membrane having a min. pore size layer different in pore size on the outside and inside surface sides thereof. The sample 16 supplied to the surface of this membrane 10 is developed in the membrane horizontal direction within the min. pore size layer by the capillary action in the membrane.

By this constitution, the particle size of fine particles in the dispersion can be judged to be simply and rapidly measured.

IPC: H03K17/16
Filed: 1987-04-03
Abstract: PURPOSE:To prevent the effect of metallic chips caused by the operation of machine tools by selecting the oscillating frequency of an oscillation circuit in a range of 3-30kHz in a high frequency oscillation type proximity switch detecting the approach of an object based on a comparison output of a comparstor circuit comparing an output of a smoothing circuit with a prescribed threshold level. CONSTITUTION:As a detection coil L2, a wire of, e.g., 0.06phi is used to form a detection coil L2a by 800-turn and the capacitance of a capacitor C3 connected in parallel is selected as, e.g., 0.01muF. In this case, denoting the inductance of the detection coil L2a by 2.5X10<-2>H, the oscillation frequency (f) of an oscillation circuit 15 is 10kHz. Thus, a frequency band being very lower than the oscillation frequency used for the high frequency oscillation type proximity switch is used. In selecting the frequency as above, the approach of an object is detected by a prescribed detection range with respect to a metallic plate made of iron or aluminum and chips of aluminum cannot be detected regardless of its approach. Thus, the presence of the object is detected based on the shape of the object being an object of detection.
