IPC: B21K1/30
Filed: 1987-02-19
Abstract: PURPOSE:To subject a material to transfer forming reasonably by composing the die of one part of fitting inner die and outer die and guiding the flow of the material in the vertical direction and horizontal direction by the outer die at the pressing time by the inner die.

Title: Device for measuring thickness of sheet material such as bank note, instruments, etc. carried
Inventor: PEETAA SHIYOORITSUHI
IPC: G07D7/12
Filed: 1989-02-14
Abstract: PURPOSE: To accurately measure the thickness of a sheet material without receiving any influence from interference signals generated by the sunlight or artificial light by providing a measuring platen, a measuring roller, and a photocell. CONSTITUTION: When a bank note passes between a measuring platen 13 and a measuring roller 14, the roller 14 is moved in the direction perpendicular to the carrying surface of the roller 14 by the thickness of the bank note. The moving amount is transmitted to the front end 24 of a long arm 22 by means of a lever 18. When the moving amount is transmitted, the amount is amplified in accordance with the length ratio between the arm 22 and a short arm 16. When the roller 14 moves, the arm end 24 enters the optical path of a photocell 32 and an electric signal proportional to the moving amount is generated. The position of the lever 18 can be adjusted by changing the angle of rotation of an eccentric member 26 by using a screw 28. Therefore, the accumulation of bank notes in front of a device for measuring thickness of sheet material can be prevented by adjusting the space between the platen 13 and roller 14 so that the space can become narrower than the thickness of the thinnest bank note to be measured by adjusting the position of repose of the lever 18.

CONSTITUTION:A funnel-shaped part 12 is formed at a base end part of an inner tube 4'' of a straw 43 and a tapered funnel-shaped part 11 at the tip part of an outer tube 4'. An air groove 14' is arranged immediately behind the funnel-shaped parts along the length thereof with a step part 17 formed at the tip thereof and a gentle inclination 18 formed in the second! half thereof. A spot-shaped notch 19 is formed on the opposite side of the air groove 14' and a hook 12 is so formed at a straight part 16 and a base end part in an inner tube 4'' that it allows the infiltration of outside air into a pack 1 to eliminate changes in the pressure during the sucking and functions as stopper in the reduction of the straw. An air groove of an outer tube allows the infiltration of the outside air into the pack during the sucking to eliminate changes in the pressure thereby preventing deformation and the generation of a strange sound during the sucking. This also provides a function to stop returning sufficiently from the inner tube to the outer tube thereby ensuring a sucking attitude shape with a specified length with an increase in the strength and rigidity.
