A pallet changer has a pallet support rotatably provided on a bed and a plurality of pallet inlet/outlets disposed on the edges of the pallet support at regular intervals. Positioning pins are biased such that they project from the bed toward the pallet support. Stops are provided on the pallet support and are engaged with the positioning pins, when the pallet support is turned through an angle corresponding to the angular distance between adjacent pallet inlet/outlets. A control mechanism is provided such that when a pallet is transferred to the pallet support through one of the pallet inlet/outlets, the positioning pin is held disengaged from the corresponding stop until the pallet support is rotated to the next stop position.

A dispenser includes a cartridge moving mechanism and a hopper. The cartridge moving mechanism moves between a cartridge receiving position and an extracting position and between the extracting position and a cartridge exhaust position. The hopper has a dropping unit and is disposed immediately above the cartridge receiving position. The dropping unit serves to drop a cartridge consisting of a fluid-impermeable outer frame and a filters. A space defined between the filters and the outer frame and contains a powdery or granular material to be extracted. An extracting mechanism of the dispenser has an upper extracting head, and a lower extracting head including an extracting tank. The upper extracting head is provided above the extracting position and has an extracting chamber. The extracting tank is provided below the extracting position to face the upper extracting head, and another extracting chamber is formed in the extracting tank. The lower extracting head has a heater for heating the extracting tank and a liquid heating passage communicating with the extracting chamber. The dispenser effectively obtains an extract from the material of the cartridge by dripping.

An outer glass pipe for a solar heat collector pipe includes an outer glass pipe body formed of a straight glass pipe being open at both ends and a lid member provided therein with a small diameter opening. An exhaust pipe of a small diameter is attached to the lid member to form a bottom member. The bottom member is air-tightly fixed to one open end of the outer glass pipe body on its peripheral edge to close one of the open ends.

A connecting member comprises a rod-shaped body having a head and/or thread on the outer periphery for integrally connecting a plurality of members and a containing hole opened at one end thereof and extended longitudinally, a rod disposed in the hole so as to fix at its inner end to the inner end of the hole, a transmissive window fixed to the opening of the hole, and a fluid holding member holding a colored fluid and pressed by the open side end of the rod on the window. When a longitudinal strain developed in the body the rod release the holding member from under pressure so that colored fluid covers the open side end of the rod.

Opti-mechanical torque indicating connecting member

In a clamping apparatus, a pressing member is moved on a base in a vertical and horizontal directions by rotation of a bolt. The bolt is provided with a longitudinal hole open end of which is covered by a window. A rod is placed in the hole so as to fix the inner end thereof to the inner end of the hole. A transparent holding member holding a colored fluid is sandwiched by the open side end of the rod and the window. When a tension stress is developed in the bolt, the open side end is far away from the holding member so that fluid covers the open side end.

Clamping apparatus

A clamping device has a clamp base having a first clamping element. A second clamping element faces the first clamping element, which moves toward the first clamping element and cooperates with the first clamping element to hold an article. A shaft is rotatably provided in the crank base such that it extends substantially at right angles to the directions in which the second clamping member moves. An eccentric is formed on the shaft. A crank lever is supported at one end by a crank holder connected to the second clamp element and fitted at the other end on the eccentric. As the shaft rotates, the second clamping element is moved towards or away from the first clamping element so as to hold the article between the elements or release the article from them.

Clamping device

A heat pipe for a solar heat collector in which a header pipe is brought into fixed surface contact with a heat-radiation portion of the heat pipe formed of a heat-conductive material. A plurality of ribs are formed of the same material as the heat pipe and extend radially from a heat-collection portion of the heat pipe. A heat-conductive plate is provided contiguous to the ends of the ribs as a unitary piece. The heat-conductive plate may be positioned in surface contact with the rear side of the heat-collecting face of a solar heat collector pipe.

Solar heat collector

An evacuated double-tubing solar heat collector including an inner tube, a selective absorption film applied over an exterior surface of the inner tube and an outer tube. The inner tube is constructed to be received within the outer tube and a spring ring is positioned on the inner tube for engaging an interior surface of the outer tube as the inner tube is inserted into the outer tube for spacing the inner tube relative to the outer tube. The spring ring is rotatably positioned on the inner tube to facilitate the insertion of the inner tube into the outer tube. Further, the inner tube includes an open end and the outer tube includes an open end which are fused to form a junction and hermetically sealed after the inner tube is inserted into the outer tube.

A solar heat collector arrangement including at least one straight-tubing type solar heat collector and first and second frame members for supporting the straight-tubing type solar heat collector. A reflector mirror is provided for directing sunrays into the heat collector. The first frame member includes a round mount opening for receiving one end of the heat collector and the second frame member includes a semi-circular groove for receiving the other end of the heat collector. Resilient annuluses are mounted on each end of the heat collector for protecting the heat collector. The heat collector, the resilient annuluses and the reflector mirror are fitted one upon another into the opening in the first frame member and on the groove in the second frame member. A retainer is provided for holding the resilient annulus and the reflector mirror from above, the retainer is mounted for detachably connecting the heat collector relative to the first and second frame members.

Solar heat collector arrangement

A spontaneous convection type solar heat collector arrangement including a reservoir in which a fluid is disposed. The reservoir includes an upper portion, a lower portion and an inner surface. At least one double-tubing type solar heat collecting tube having an open end and a closed end is positioned within at least one connecting opening provided in the lower portion of the reservoir. Insulating material is operatively positioned around the reservoir for protecting and insulating the reservoir. The open ends of said double-tubing type solar heat collecting tube is positioned in a fixed fluid-tight manner to the connecting opening and is mounted flush with the inner surface of the reservoir for increasing the area of fluid circulation within the reservoir.
