Title: Method for checking axial tension of bolt
Inventor: DOUGAHARA TAKASHI
IPC: G01L5/00
Filed: 1986-12-25
Abstract: PURPOSE:To easily check accurate axial tension, by bringing an axial tension check gauge into contact with the top surface of the head part of a bolt and checking axial tension on the basis of the contact and separation states of said gauge and the top surface of the head part of the bolt. CONSTITUTION:An axial tension check gauge 13 is constituted by smoothly finishing the under surface of a gauge main body 14 composed of a high hardness metal block and providing a recessed part having an accurate depth to a part of said under surface. After torque is applied to the bolt to tighten said bolt, the axial tension check gauge 13 is brought into contact with the top surface 8 of the head part 2 of the bolt main body 1. Whereupon, since the protruding quantity of a pin 6 is large when axial tension is small, the leading end 7 of the pin 6 protruding from the top surface 8 impinges against the bottom surface of the recessed part 14 of the axial tension check gauge 13. Therefore, a gap (g) is formed between the top surface 8 and the axial tension check gauge 13 and, when axial tension is large, the under surface of the gauge 8 is brought into contact with the top surface 8 and no gap (g) is formed. As a result, by the presence of the gap (g) between the top surface 8 of the head part 2 and the gauge 13, it can be checked whether axial tension is applied.

IPC: B41N1/24
Filed: 1994-12-12
Abstract: PURPOSE: To reduce splashing defect due to the going round of ink to the reverse side of a plate and consequently realize highly fine screen printing by a method wherein water repellency is given to the surface of the emulsion layer of a screen printing plate or the contact angle of its surface to water is made not less than a specified angle. CONSTITUTION: After emulsion 2 is applied to the portion excluding the mesh opening part of a screen printing plate 1, a polymer resin having a fluorine- containing aliphatic ring structure is applied to the rear side of un-exposed printing plate and then dried so as to form film 3. Thus, the contact angle of the surface of the emulsion layer 2 to water becomes not less than 90 deg. or its surface has water repellency. Accordingly, even with water-based ink, which is called to be inferior in printing rheology, highly fine screen printing having the same fineness as that with an organic solvent-based ink can be stably performed without changing the composition system of the ink.
