摘要:
In order to suppress the occurrence of damage on a press-fit joining wiring board, a peak value of stress generated on the board in the case of a press-fitting a press-fit terminal into a through-hole is reduced so that it can not exceed the design standard value of the board. In the press-fit terminal in which a body part, retaining part, introducing part and forward end part are integrally formed, a cross-sectional area of the introducing part is reduced to be smaller than that of the retaining part, so that an intensity of the elastic force of the introducing part is decreased to be lower than that of the elastic force of the retaining part. Alternatively, on the wiring board, elastic material is filled into resin for combining sheet-like base material of the board so as to relieve an intensity of stress generated on the board itself.
摘要:
An electroluminescent light emitting system, having an electroluminescent light-emitting layer containing electroluminescent light-emitting elements, one surface side of which receives an AC electric field forming material thereon; an electrode section including a first electrode layer with a predetermined first pattern and a second electrode layer with a predetermined second pattern, which are disposed relatively close to but electrically spaced from each other on another surface side of the electroluminescent light emitting layer; and a waterproof resin layer provided between at least one of the first electrode layer and the second electrode layer electrode section, and the electroluminescent light-emitting layer. The AC electric field forming material on the one surface side enables an AC electric field to be generated in the electroluminescent light-emitting layer with an AC voltage applied between the first electrode layer and the second electrode layer.
摘要:
A method for producing a food shaped as a continuous bar by placing a continuous inner material on a continuous strip of an outer layer material that is transferred on a former belt, comprising the steps of placing food material that includes the inner material placed on the strip of the outer layer material in a channel space defined by the former belt while it is running; and shaping part of the former belt that is located at the channel space as a sleeve by pushing and joining edges of the former belt by a pushing device to allow edges of the outer layer material to be joined.
