Abstract: An overhead hoist transfer apparatus includes a rail assembly including a straight rail having an empty section, and a curved rail having a curved empty section; an engine including a first LSD having first and second wheels at two sides respectively; and a second LSD having third and fourth wheels at two sides respectively; a moving carriage driven by the engine and suspended from the rail assembly; first and second guide wheels disposed on the first LSD; third and fourth guide wheels disposed on the second LSD; and two guide boards disposed above a joining point of the straight rail and the curved rail. An elevation of the guide boards is equal to that of the guide wheels. The guide board includes a straight edge and a curved edge.

Abstract: A powered industrial truck includes a lateral movement assembly including four sliding members and four pivotal members both on a wheeled carriage, four links having a first end pivotably secured to the sliding member and a second end pivotably secured to either end of the pivotal member, a motor shaft having two ends pivotably secured to the pivotal members respectively, a first electric motor on one frame member, and four mounts attached to the sliding members respectively; two lift assemblies including a second electric motor, a shaft having two ends rotatably secured to the sliding members respectively, two gear trains at the ends of the shaft respectively, a first gear connected to the second electric motor, a second gear on the shaft, and a first roller chain on the first and second gears; two electric attachments on the platform and being laterally moveable, each attachment. The mount has rollers.

Abstract: The present disclosure provides a probing apparatus for semiconductor devices using pressurized fluid to control the testing conditions. The probing apparatus includes a housing configured to define a testing chamber; a device holder positioned on the housing and configured to hold and support at least one device under test; a platen positioned on the housing and configured to retain at least one probe; a card holder positioned on the platen and configured to hold a probe card including the probe; and at least one flow line positioned in the card holder. The flow line is configured to flow a fluid therein to adjust the temperature of the device under test.
