    Abstract: Provided is a multi-leaf spring-type vibration damping device capable of suppressing the resonance caused by rotations near the major critical speed of a rotating shaft system and suppressing self-excited vibrations due to rotations at or higher than the major critical speed of the rotating shaft system. In the multi-leaf spring-type vibration damping device, a bearing (9) of a rotating shaft system (6) that includes at least a rotating shaft (4) fit in the bearing and a rotor (5) mounted on the rotating shaft is clamped between a plurality of fixedly mounted and properly spaced-apart multi-leaf springs (11) at the portions near their distal ends, or the plurality of multi-leaf springs contact at those portions near the distal ends with the bearing, thereby to suppress the whirling vibrations of the bearing. The multi-leaf spring-type vibration damping device is characterized in that each multi-leaf spring is made into a multi-leaf spring unit (14) that has a double multi-leaf spring structure in which an auxiliary multi-leaf spring (13) having a structure substantially identical to that of the multi-leaf spring is faced and fixed at its portion near the proximal end of it to a portion near the proximal end of each multi-leaf spring through a spacer (12), and in which the distal end of the auxiliary multi-leaf spring is in advance forced in a direction opposite the multi-leaf spring so as to have a resilient force of a predetermined magnitude.

    Abstract: When a sintered body of ceramic is shot-blasted at normal temperatures to plastically deform the crystal structure of the shot-blasted surface to apply residual stress and is heat-treated to recrystallize fine cracks, dislocated cells in the grain boundary are formed, crystals are finely divided, and the fracture toughness is significantly improved. When the sintered body of ceramic is a thin product, an effective toughening can be attained by shot blasting both the front and back sides. After heat treatment, mechanical strength is significantly improved by removing a part of the modified surface layer by an abrasion treatment.
