  • Shifting-transfer mechanism
    Patent number: 6845683
    Abstract: A shifting mechanism includes a limit switch that sends an open-close signal of the switch contacts SW1, SW2, SW3 and SW4 out to a control mechanism according to a 2H-4H-N-4L shifting sequence. The switch contacts SW1 and SW2 detect the position of a slider 4H which is moved by a thrust actuator, during shifting in the range of 4H engagement to the range of N engagement. Therefore, if one of the switch contacts SW1 and SW2 is faulty, the other switch detects shifting between 4H and N. This prevents shifting into N over 4H, thereby preventing malfunction of the thrust actuator resulting from a faulty switch contact SW1 or SW2. This also avoids potential difficulties in vehicle control due to shifting characteristics and permits the maintaining of controlled driving.

  • Tool chuck for a hand-held power-driven punching machine or the like
    Patent number: 6457243
    Abstract: A punching machine has a power-driven plunger to which a punch is chucked to be driven into and out of a die for perforating sheet-metal work. The plunger has a punch socket formed centrally in its end for receiving the shank of the punch, and a plurality of ball guideways extending radially outwardly from the punch socket. Locking balls are slidably received one in each ball guideway for movement into and out of locking engagement in an annular groove in the shank of the punch received in the punch socket. Concentrically mounted on the plunger, a cam ring is sprung in one axial direction of the plunger for urging the locking balls into locking engagement with the punch shank. Each locking ball is elongated radially of the plunger with a view to reduction of the machine dimension axially of the plunger for given diameters of the plunger and the punch.
