Title: Gate mechanism for transferred cylinder body
Inventor: SAKURAI KEIZO
IPC: B65G47/08
Filed: 1988-05-17
Abstract: PURPOSE:To make stop and release smooth and reliable in a gate mechanism of a conveyor or the like by disposing a stopper plate made of a disk with its outer circumference formed with arcuate recesses of a radius smaller than the radius of a cylindrical body on a base plate capable of advancing and retracting elastically relative to a travel path and controlling it by means of an external signal. CONSTITUTION:A hook 7a of a restraint lever 7 engages with a bolt head portion 6of a stopper plate 3 projecting by a maximum limit from an opening Ga of a guide wall G into a travel path to make the stopper plate 3 immovable. A cylindrical vessel B transported by a conveyor C comes into contact with an end 3a of an arcuate portion 3b of the stopper plate 3 and stops. When a solenoid 12 is urged by a control signal to retract the restraint lever 7 and release the bolt 6, the stopper plate 3 is rotated by the conveyor C and by the vessel B being urged forward so that the vessels B are passed through in succession. This arrangement makes the stop and release smooth and reliable.

Filed: 1984-06-11
Abstract: PURPOSE:To obtain a reproduction head having high reproduction efficiency and high reliability by providing a magnetic detection element on a substrate opposite to the magnetic surface of a magnetic recording medium together with a nonmagnetic film having the wear resistance for protection of said detection element. CONSTITUTION:A substrate 21 of glass, sapphire, etc. is polished so that the face at the side opposite to a magnetic recording medium is turned into a curved surface having a circular arcuate section. An MR element 22 is formed on the substrate 21 approximately at an apex at the side of the rubbing surface of the recording medium. An electrode 23 is also formed on the substrate 21 together with a nonmagnetic film 24 which protects the element 22. The element 22 totally pinches the film 24 and approximately has a close contact with the recording medium. Thus a sufficient magnetic field is applied to the element 22 with a thin film type reproduction head. Therefore this reproduction head has higher efficiency of reproduction than a non-shielded reproduction head.
