摘要:
A method of measuring adhesive strength between an element body and a porous protection layer that are included in a sensor element includes (a) a step of holding a portion of the element body where the porous protection layer is absent with an elastic force exerted by a holding jig, and placing a peeling jig at a position between the porous protection layer and the holding jig in the longitudinal direction such that the element body is allowed to move in the longitudinal direction while the porous protection layer is prevented from moving in the longitudinal direction toward the holding jig; and (b) a step of moving, after the step (a), the peeling jig pushes the porous protection layer in the longitudinal direction, and measuring the adhesive strength of the porous protection layer.

A coupon suitable for peeling tests, derived from a vane and comprising: (i) a portion of blade that comprises a frontside surface, a backside surface and a leading edge and/or trailing edge and (ii) a vane reinforcement that covers and is glued to at least a part of the frontside surface, a part of the backside surface and which extends beyond the leading and/or trailing edge. The reinforcement is split over the entire length of the leading edge and/or trailing edge such that the reinforcement is separated into two plates separate from one another and facing each other on either side of the slit beyond the leading and/or trailing edge. Furthermore, at least one of the plates furthermore comprises, beyond the leading and/or trailing edge, fastening means providing a hold to this same plate.

A transducer assembly is provided. The transducer assembly includes a magnetic portion, a body, a tensile pulse transmitter, and a pulse and current control unit. The magnetic portion is configured to provide a magnetic field. The body is disposed within an opening of the magnetic portion, and has a conductive portion configured to pass electric current near a body surface oriented toward the test surface. The tensile pulse transmitter is disposed within a cavity of the body and configured to transmit a tensile pulse into the test object. The pulse and current control unit is configured to control the tensile pulse transmitted by the tensile pulse transmitter, and to provide a current that passes through the conductive portion of the body and the test object, whereby a force urging the transducer assembly and the test object toward each other is generated responsive to the magnetic field and the current.

The present application relates to a pressing and tearing apparatus and method for peeling rate tests, wherein the apparatus comprises a working table configured to place a sample; a press mechanism disposed above the working table, and being capable of synchronously rolling and translating relative to the working table; an input unit configured for inputting a preset pressing force value and a preset tearing force value; a pressure sensor and tension sensor; a controller electrically connected to the input unit, the pressure sensor, and the tension sensor respectively; and a drive mechanism configured to drive the working table to move upward or downward and drive the press mechanism to roll and translate synchronously relative to the working table under the control of the controller.
摘要:
A wearable article with an extensible fastening member having a fastener proximate its end is disclosed. The fastening member may be highly extensible, and may have construction features and shape characteristics that affect distribution of force components when the fastener is in use, and reduce the chances of buckling or flipping of the fastening member along its edges, and the chances that the edges of the fastener will be lifted away from a surface to which it is attached. The fastener and material forming an accompanying landing zone on the article may be selected to form a fastening combination having performance attributes that provide further resistance to unintended pop-off under wearing conditions.
摘要:
An object is to provide a peel tester that continuously detects the characteristics of an adhesive tape from the moment an impact is applied to an adherend until the adherend is peeled, and a new method for evaluating the impact peel characteristics of an adhesive tape, which enables quantitative evaluation for the impact peel characteristics by using the test result obtained by the peel tester. Provided is a peel tester 1 with a main body 2, to which an adherend I is to be adhered via an adhesive tape III, for performing a peel test by an impact applied to the adherend I, which includes: a load detection device 6 that detects change in load applied to the adhesive tape I until the adherend I is peeled off from the main body 2; and a displacement detection device 7 that detects change in moving distance of the adherend I until the adherend I is peeled off from the main body 2.
摘要:
An object of the present invention is to provide a method for evaluating the physical strength of husks of a barley ingredient for malt manufacture. Barley kernels with husks are disposed in a sulfuric acid solution with a concentration of approximately 40% to 60%, and are agitated for a prescribed time (e.g. approximately 1 hour) using a stirrer bar or the like. After agitation, the barley kernels are treated with a mixed liquid of Methylene Blue and Eosin, and the degree of peeled husk (remaining degree) is examined by referring to the degree of dyed barley kernels, to thereby evaluate the physical strength of the husks of the barley kernels.
