摘要： An induction heating apparatus heats content efficiently while measuring a temperature of the heated content accurately. The induction heating apparatus includes a can holder, a heating coil disposed around the can holder, and a temperature measuring unit. A resealable metal beverage can having a thread formed on a neck portion and a cap screwed onto the neck portion is held by the can holder. The can holder holds the metal beverage can in a manner such that the cap of the can inserted thereto is exposed on an axially upper side. The temperature measuring unit measures a surface temperature of the cap of the metal beverage can held in the can holder.

摘要： In a ratchet-type tensioner having a plunger with rack teeth formed thereon and a piston with ratchet teeth that engage the rack teeth, the ratchet teeth can be disengaged from the rack teeth by insertion of a tool through a tool insertion hole in the tensioner housing and exerting a prying action on the toothed end of the piston to move the piston away from the plunger. Alternatively if an oblique camming surface is formed on the toothed end of the piston, the ratchet teeth can be disengaged from the rack teeth by pushing the tool inward against the oblique camming surface. The piston and the hole in which it slides are shaped to prevent rotation of the piston. The ratchet teeth on the piston and the rack teeth on the plunger can be oblique to allow setback of the plunger when excessive force is exerted on the plunger.

摘要： In a ring-type tensioner, an expansible elastic ring disposed in a groove formed in the wall of a plunger-accommodating hole cooperates with teeth formed on the plunger to restrict axial movement of the plunger. The ring and the groove in the wall of the plunger-accommodating hole have flat radial surfaces for mutual engagement. However the ring also has oblique plunger-tooth engaging surfaces. The ring has manipulable end parts that can be locked in fixed relation to each other by a tool to secure the plunger against axial movement. The tool can also be inserted into a gap between the manipulable end parts to expand the ring and thereby release the plunger.
