摘要： The pressure-sensitive resistor comprising an electroconductive elastomer, in which an electroconductive particulate material is dispersed, two electrodes placed on the opposing surfaces of the elastomer, a means for providing a compressive force between the electrodes and a means for adjusting the compressive force, works on a novel principle that the elastomer composite exhibits a positive coefficient in the curve of compression vs. resistance relationship when the compressive force is varied in a region exceeding an inversion point at which the resistance of the elastomer as measured in the direction of compression is minimal. The coefficient in this positive region is smaller than in the ordinary negative region, so that the variable resistance of the resistor can be controlled very delicately together with the decreased contribution of the uncontrollable contact resistance.

摘要： An improved pressure-sensitive resistance element is provided which is composed of an electrically non-conductive matrix of a rubbery elastomer and electrically conductive particles dispersed therethrough to have a gradient of distribution from one side to the other of the matrix. Such resistance elements can be manufactured by preliminarily mixing a fluid silicone rubber composition with the conductive particles to be uniformly dispersed therein and subsequently subjecting the mixture to curing to form a rubbery elastomer while, concurrently, the particles are naturally or by force allowed to settle to form the gradient of distribution within the matrix. The resistance elements are superior in easily obtaining the desired resistivity in a wide range by adjusting pressure applied thereto as well as a long service life, compared to products of the kind hitherto known.

摘要： The adjustable and readily solderable sheet-like connector of the invention is composed of an insulating sheet-like elastic body, a plurality of parallel-running wires of a soft and plastically deformable metal or alloy integrally bonded to the surface of the sheet-like body forming an array of parallel electroconductive paths and a soldering layer at least partly covering the exposed array of the metal wires as formed of a composite material composed of a plastically flowable material such as a hot-melt adhesive and particles or chopped fibers of a solder alloy dispersed therein. The connector is easily bent and left in the bent form just like an adjustable ruler to comply with any curved surface of a printed circuit board and readily bonded to the printed circuit board by heating and pressing between hot plates to cause melting of and soldering with the particles or chopped fibers of the solder alloy contained in the soldering layer at the portions just between each set of the metal wires and the connecting terminals on the printed circuit board due to the better heat conduction there than in the other portions at which the soldering layer is left electrically insulating.

摘要： The invention provides an improvement in a socket-type connector used for making electric connection between two circuit units. Unlike a conventional socket-type connector in which a contacting element made of a metal piece in a form of something like a spring is fixed in a rigid socket, at least a part of the socket of the inventive connector is made of an electrically insulating and elastically resilient material so that a pin plug inserted into the socket is held firmly and in good reliable contact with the contacting element by virtue of the elastic resilience given by the part of the socket made of the elastically resilient material where the socket is deformed by the insertion of the pin plug to exhibit rubbery resilience.

摘要： The invention provides a push button switch covering member integrally made of a rubbery elastomeric material having an improved structure with which a much larger key stroke is obtained before a snapping action takes place in the covering member when the member is pushed at the center portion leading to the contact of the contact points than in the conventional ones. The covering member is constructed of (a) a central pushing part, (b) a first annular portion which may be in a form of a truncated cone or a cup laid upside down and is connected to the central pushing part at the upper end, (c) a second annular portion encircling and connected to the first annular portion and (d) a base flat connected to the second annular portion, at which the covering member is mounted on the base board of the switch, the relationship between the strengths of the first and the second annular portions being such that the first annular portion does not undergo a buckling deformation before the second annular portion is substantially deformed or bent around the connecting line between the second annular portion and the base flat.

摘要： The invention provides a novel key board switch unit with illumination in the pushing areas, e.g. push buttons. Different from conventional ones, the pushing areas in the inventive unit are illuminated indirectly with the light emitted from a lamp positioned at a remote place not directly visible from above the pushing areas and, instead, an optical conductor member made of a transparent material is provided between the lamp and the pushing areas to be illuminated. The inventive key board switch unit can be very compactly designed despite the sufficiently high but not glaring intensity of illumination facilitating the operation of the switches even in a dark place.

摘要： The invention provides a novel push-button switching means for producing an electric signal free from the problems of chattering or bouncing unavoidable in the conventional switches relying on the principle of mechanical contacting and coming apart of the contact points. The inventive push-button switching means comprises a pressure-sensitive unit composed of a resistor body formed of an electroconductive rubbery elastomer exhibiting a minimum in its electric resistivity when subjected to compression with an increasing pushing force reaching a strength in excess of a certain critical strength and a pair of electrodes provided on the surface of the resistor body. When the pressure-sensitive unit is pushed with a force in excess of the critical strength to compress the resistor body and then released, the resistivity of the resistor body exhibits two minimum values in the courses of the pushing and releasing and, correspondingly, two maxima are obtained in the electric current through the resistor body with application of a predetermined voltage between the electrodes. These two successive peaks of current are detected by a detecting circuit which produces a single electric signal in response thereto.

摘要： A pressure sensitive multiple resistor element is proposed whereby two or more variations of resistance can be obtained simultaneously by applying a single compressive force. It comprises an anisotropically electroconductive composite sheet exhibiting varied resistance between its opposite surface as a result of the compressive force applied thereto, a set of electrodes provided on one surface of the composite sheet, another set of electrodes provided on the other surface, and a means for applying the compressive force to the composite sheet through the electrodes. The anisotropically electroconductive composite sheet is formed of an electrically insulating rubbery elastomer as the matrix within which many electroconductive fibers are dispersed and oriented in the direction perpendicular to the plane of the sheet.
