Abstract: A commutator includes an insulating section that is formed in a tube shape including a shaft insertion hole through which a shaft is inserted, and that is formed with an indented portion in an end portion at one side in an axial direction of the shaft. The commutator also includes plural segments that are supported by an outer peripheral portion of the insulating section, that are arrayed around a circumferential direction of the insulating section with spacings therebetween, and that are each provided with an anchor portion at an end portion at the one side in the axial direction of the shaft. The commutator also includes a first, second, third short-circuit wires, each connecting the anchor portion of respective one segment to the anchor portion of respective another segment, and at least a portion being disposed inside the indented portion formed at the insulating section.

Abstract: A dehumidification system includes a first dehumidification unit having an outdoor air cooling heat exchanger, a second dehumidification unit using two adsorption heat exchangers such that an air passage is switched, and a third dehumidification unit having an adsorption rotor. Low-temperature low-humidity air cooled and dehumidified in the second dehumidification unit is supplied to the third dehumidification unit to reduce energy for recovery of the third dehumidification unit and to realize energy conservation in the dehumidification system and reduction in cost of the dehumidification system.

Abstract: First and second adsorption heat exchangers are provided for first and second heat exchange chambers, respectively, and each interchangeably function as an evaporator or a condenser. If the first adsorption heat exchanger functions as an evaporator in the first heat exchange chamber, a first adsorption block is arranged at a position downstream of the first adsorption heat exchanger. If the second adsorption heat exchanger functions as an evaporator in the second heat exchange chamber, a second adsorption block is arranged at a position downstream of the second adsorption heat exchanger.

Abstract: A dehumidification system for a dry clean room includes: a dry chamber supplied with air having a lower humidity than air in the dry clean room; a main dehumidification unit which supplies air to the dry clean room; and a terminal dehumidification unit which processes the air to be supplied from the dry clean room to the dry chamber, thus achieving energy saving and cost reduction for the dehumidification system for the dry clean room.

Abstract: An indoor unit of an air conditioner is capable of both enhancing the design thereof and preventing the reduction of the air blowing performance. The indoor unit of an air conditioner has a front grill and a design panel. The front grill is provided with an outlet. A front panel covers the outlet in the front view during shutdown, and moves so as to open the outlet during operation.

Abstract: The present invention provides an indoor unit of an air conditioner, which is capable of improving the mounting accuracy between a front grill and a movable panel. An indoor unit of the air conditioner includes a main body casing, a front grill, a second panel, a driving machine, and an opening and closing mechanism. The front grill is provided forward of the main body casing and includes a first intake port. The second panel is capable of moving so as to open and close the first intake port. The driving machine is provided in the main body casing, and generates a driving force to move the second panel. The opening and closing mechanism is provided at the front grill, and moves the second panel by the driving force of the driving machine to open and close the first intake port.

Abstract: A refrigerant circuit is formed by connecting an outdoor unit (5) and an indoor unit (6) to each other with communication piping (18) including a gas pipe (16) and a liquid pipe (17). An alternative refrigerant R-410A is used as a refrigerant to be circulated through the refrigerant circuit. For middle-sized and large-sized air conditioners whose rated cooling power (JIS C 9612) is not less than 4.0 kW, a gas pipe (16) having an outer diameter of about 9.5 mm (with wall thickness 0.8 mm) is used. For small-sized air conditioners whose rated cooling power (JIS C 9612) is less than 4.0 kW, a gas pipe (16) having an outer diameter of about 7.9 mm (with wall thickness 0.8 mm) is used.

Abstract: Disclosed is a printing die replacement assisting unit for facilitating die replacement by an operator in a printing apparatus having a plate cylinder rotatably supported in the main body of the apparatus with a printing die having engagement plates being mounted on the circumference of the plate cylinder, the printing die replacement assisting unit comprising a support frame disposed on the main body, with a fitting member being descendably supported on supporting means disposed on the support frame; holding means disposed to the fitting member, which can releasably hold one of the engagement plates of the printing die; and an urging means connected to the supporting means, which normally urges the means in the direction such that the fitting member may be ascended, but allows pulling down of the fitting member; wherein the printing die is designed to be held by and suspended from the fitting member via the holding means.
