An apparatus for guiding a biomedical electrode is provided, which guides a biomedical electrode to be brought into close contact with a living body surface of a voluntary muscle into optimum close contact positions on the basis of positions of the voluntary muscle and a neuromuscular junction of the voluntary muscle inside the living body surface. The relative positions of the voluntary muscle and the neuromuscular junction of the voluntary muscle to the living body surface are detected from muscle action potentials detected by myoelectric detection electrodes put into close contact with a large number of positions on the living body surface. On the basis of the relative position information, a close contact position of the biomedical electrode to be brought into close contact with the living body surface of the voluntary muscle is guided to an optimum position.

An object of the present disclosure is to provide a muscle condition measurement sheet that can quantitatively detect the amplitude and latency of an evoked electromyogram EMG or an evoked mechanomyogram MMG and correctly evaluate the state of activity of a muscle. A pair of stimulating electrodes and all myoelectric detection electrodes come into intimate contact with a body surface of a muscle, appearing on a back surface of an insulating sheet spaced at predetermined intervals; accordingly, the relative position between an electrical stimulation position and the myoelectric detection electrode is fixed and the amplitude and latency of the evoked electromyogram EMG can be quantitatively detected without depending on the stimulation position of an electrical stimulation signal.

The respective proportionality constants of magnetic force by magnetic field producing portion for biasing the plug in the direction of insertion and resilient force by a spring mechanism for biasing the plug in the direction of extraction are adjusted in such a manner that the resilient force is greater than the magnetic force until the plug pin reaches an intermediate insertion position at which the plug pin comes into proximity to or separates from the socket contact, whereas the magnetic force is greater than the resilient force at a position at which the plug pin is inserted into a complete insertion position for a hot-line connection to the socket contact. The plug pin in the vicinity of the intermediate insertion position, at which there is a possibility of occurrence of an arc discharge, is ejected by the resilient force.

A method for cold-forging a thin-walled portion by which a thin-walled portion having a set thickness is formed directly from a metal base plate having a sufficiently large thickness and an explosion-proof valve are provided. Blade side surfaces of upper and lower dies for shearing the metal base plate are set in an overlapping manner with a predetermined clearance &#x3b4; therebetween. Sheared surfaces are formed with the blade side surfaces of the upper and lower dies in the metal base plate along a processing direction while leaving the set thickness t2 therebetween and the metal base plate is compressed by the overlapped portions until work-hardened to form the thin-walled portion with the horizontal width &#x3b4; and the set thickness t2 between the sheared surfaces. The formation of the sheared surfaces eliminates a need to press portions of the metal base plate positioned at both the sides of the thin-walled portion into both the sides during the processing of the thin-walled portion and the thin-walled portion can thus be formed at a high compression processing rate with a smaller processing load.

A contact structure is provided. The contact structure suppresses arcing that can occur between contacts that establish a live connection, without increasing the size of the contact structure, and without making longer the length of the inserting/drawing stroke of a correspondingly formed contact. A live contact portion of a first contact, and an auxiliary contact portion of an auxiliary contact body configured with a high resistance resistor having a base end connected portion that establishes an electrical connection with the first contact front on a movement path of a second contact at positions that are shifted in front and rear directions while being distanced by a width that allows simultaneously contact with the second contact. If the second contact separates from the first contact, the auxiliary contact body configured with the high resistance resistor intervenes between the first contact and the second contact, and inhibits arcing.

Contact structure

The present invention is intended to provide a contact contacting structure for hot-line connection between contacts configured such that the occurrence of arc discharge between contacts is suppressed by a simple configuration. At least one of contact/separation contact surfaces in a pair opposed to each other at the contact/separation position between a first contact and a second contact is covered with an oxide film. At the time of contact or separation of the first contact and the second contact, the oxide film as an insulator intervenes between the paired contact/separation contact surfaces to decrease energy accumulated between the first contact and the second contact at the instant of contact or separation of the two contacts, thereby suppressing the occurrence of arc discharge.
