Provided is a pair of arc discharge suppressive terminals electrically communicable with each other by engagement of the terminal pair. At least one of the terminal pair has a final contact site which is in contact with the counterpart terminal at a final stage of disengagement of the terminal pair. At least the final contact site is covered with an arc discharge suppressive layer containing a first metal having a melting point of 1,550° C. or higher. It is preferable that the terminal pair contact with each other at a portion corresponding to a main contact site other than the arc discharge suppressive layer in a completely engaged state where the one of the terminal pair and the counterpart terminal are tightly engaged with each other. Preferably, the main contact site has a surface made of a material having a higher conductivity than the arc discharge suppressive layer. This arrangement effectively suppresses occurrence of arc discharge at a time of disengagement of the terminal pair.

In a liver function testing apparatus, light sources (11, 12) expose vital tissue (15) to first light of a wavelength absorbed by the specific dye dosed into blood of the vital tissue to be taken in and removed by the liver and second light of a wavelength not absorbed by the dye. Optical pulses passing through the vital tissue are received by a light receiving element (13) and first and second outputs from element (13) are sampled by an A-D converter (30) to produce respective digital signals. Pulsation components of the outputs of the receiving light are detected by high-pass filters (51, 52) and amplifiers (53, 54). A coefficient of a linear regression expression between intensity values of the pulsation components and an average value using the sampled first and second outputs of the received light are determined for performing a biocalibration. A value correlated with a specific dye concentration in the blood is calculated based on sampling outputs during a prescribed period and based on the determined average value after injection of the specific dye. Thus, a coefficient of a simulation function as a time function, is obtained by using the method of least squares and a blood plasma disappearance rate and a retention rate are obtained on the basis of the coefficient of the simulation.
摘要:
A CT computed tomograph comprises a scanner (51) which surrounds a living body of a person to be examined. Ultrashort light pulses of the ith wavelength are applied to the living body from a sample light transmitting path (80k) corresponding to the kth cell of this scanner and the sample light pulses received by a sample light receiving path (81l) corresponding to the lth cell and reference light pulses transmitted from a reference light path (79) and a delay light path (78) are converged by a converging lens (75). A CPU(64) counts photons outputted from a photomultiplier (22) based on the converged light pulses and calculates an average value by averaging a predetermined number of count values. A delay amount of the reference light pulses through the delay light path (78) is changed based on the average value and, based on delay time and an average value in the delay time, a photon count value S.sub.0i (k, l) obtained by counting the photons of the second harmonic when the delay amount of the reference light pulses is a predetermined value is stored. Based on the photon average value S.sub.0i (k, l), a tomographic image of the metabolism of the living body is evaluated.
摘要:
A mechanism for bending an elongated body such as the tube of an endoscope without the use of electric elements, thereby eliminating a shock hazard. A shape-memorizing alloy is inserted into the elongated body at portions to be bent. In some embodiments, heat for causing the shape-memorizing alloy and hence the elongated body to bend is produced by light carried by an optical fiber, while in other embodiments frictional heat produced by a mechanism vibrator is employed. In some embodiments using light, a shutter arrangement is added to control the heating of the shape-memorizing alloy.
