A borehole is bored to a borehole target depth in a site and a geothermal heat exchanger is inserted into and then secured in the borehole at the desired depth. Once the heat exchanger has been secured in the borehole, the heat exchanger has a closed distal end and an open proximal end and has at least one fluid path between the closed distal end and the open proximal end, with installation fluid disposed in the fluid path(s). After securing the heat exchanger in the borehole and before excavation of a portion of the site immediately surrounding the borehole, the heat exchanger is temporarily sealed by installing, through the open proximal end, at least one respective internal seal in each fluid path. For each fluid path, the internal seal(s) will be disposed below a respective notional subgrade depth and excavation of the site immediately surrounding the borehole can proceed.

A lift mechanism of a die set apparatus includes a guide pin, a linear motion guide member, a first washer, a second washer, a first coil spring, and a second coil spring. A first positioning portion and a second positioning portion control a first end turn portion and a second end turn portion from moving in a radial direction of the guide pin in a state where a first gap is formed between the first coil spring and the guide pin. A third positioning portion and a fourth positioning portion control a third end turn portion and a fourth end turn portion from moving in the radial direction of the guide pin in a state where a second gap is formed between the second coil spring and the guide pin.

A cutting apparatus cuts a fabric using a rotary blade and a fixed blade that are built into a cutter head. The fixed blade is linked, to the other-end side of a swing arm of which one end is pivotally fitted on a blade frame by a swing shaft. The fixed blade is urged by a coil spring connected to the one-end side of the swing arm. When a prescribed resistance force is applied to the fixed blade, a position sensor detects movement of the swing arm, a fixed blade drive cylinder drives the swing arm in response to the detection, and the fixed blade is moved to an accommodation position that is above the position during cutting and that is on an opposite side in the advancing direction of the cutter head.

A perforating apparatus may have a first roll comprising a first design and a second roll comprising a second design, each roll being in close proximity with a support member and each roll comprising a blade or an anvil. A web material may travel a first path between the first roll and the support member or, alternatively, may travel a second path between the second roll and the support member.

A slitting machine for removing a strip from a sheet of material. The slitting machine has a blade assembly with first and second cutting blades, and a perforating blade arranged between the first and second cutting blades. The first and second cutting blades are arranged to cut the sheet of material to define the strip and the perforating blade is arranged to perforate the sheet of material to define an end of the strip.
