Filed: 1989-12-21
Abstract: PURPOSE:To extend the lifetime of a printing hammer and to improve its reliability by brazing the thick-wall parts of T- and U-shaped hinges in a state where the thick-wall parts protrude from the end faces of fixing members. CONSTITUTION:T- and U-shaped hinges 1, 2 are brazed by low stress thick-wall parts (1b, 1c) and (2b, 2c) causing almost no bending deformation and the thick- wall parts (1b, 1c) and (2b, 2c) protrude from the end faces of members 11, 16 to which the thick-wall parts are fixed. Consequently, a brazing filler metal 4 is prevented from flowing out by the thick-wall parts (1b, 1c) and (2b, 2c) and no brazing filler metal 4 adheres to thin-wall parts 1a, 2a causing a bending deformation. As a result, no stress concentration due to cracking of the brazing filler metal 4 occurs in respective hinges 1, 2 so that the hinges have a long life and are improved in reliability.

IPC: G11B21/22
Filed: 1989-12-25
Abstract: PURPOSE:To realize this carriage locking mechanism capable of performing a compression operation with a few amount of current by comprising the mechanism in such a manner that a carriage is locked in the vicinity of a stopper CONSTITUTION:When the power source of a magnetic disk device is turned off, the carriage 33 is energized in a direction of stopper 31 with a return spring, and approaches the stopper 31. When the current supplied to a coil 45 is stopped, a plunger 43 is protruded from a case with a spring 44, and is engaged with the groove 34a of a projection 34, which generates a carriage locking state. Therefore, since carriage lock is performed at a state where the projection 34 is not abutted on the stopper 31, it is not required to deflect the stopper in performing compression managing with few current consumption. Thereby, it is possible to realize the carriage locking mechanism capable of performing the compression operation with a few amount of current.
