Abstract: An air conditioner includes: a duct including an upstream flow path unit having an inlet through which air is taken in, and a downstream flow path unit provided with an outlet through which the air is discharged; a cooling unit positioned in the upstream flow path unit of the duct and cools the air; and a heating unit that is positioned in the downstream flow path unit of the duct and heats the air. The upstream flow path unit has a partition plate that partitions an inside space thereof into a main-flow flow path and a sub-flow flow path. The cooing unit is positioned in the main-flow flow path. The upstream flow path unit is provided with a flowrate adjusting member that covers at least a part of the sub-flow flow path so as to adjust an opening area of the sub-flow flow path.

Abstract: An air conditioner includes: a cooling unit having a compressor operated at a variable operating frequency to adjust a revolving speed thereof, a condenser, an expansion valve and a cooling coil; and a heating unit for causing the heating medium flowing from the compressor toward the condenser to diverge, and to return to flow into the condenser, through a heating coil and a thermal dose adjusting valve disposed on the downstream side thereof; so as to control a temperature of air by the cooling and heating coils. When an opening manipulated variable of the thermal dose adjusting valve exceeds a first threshold value over a period of time, an operating frequency of the compressor is decreased, and when the opening manipulated variable of the thermal dose adjusting valve falls below a smaller, second threshold value, over the said period of time, the operating frequency of the compressor is increased.

Abstract: A sealant applying apparatus includes a fastener rotating unit which supports a fastener to be rotatable around a central axis, and a sealant discharging unit which applies a sealant to the fastener by discharging the sealant. The fastener rotating unit includes a first holding member and a second holding member which hold the fastener to be rotatable, and a base which supports the first and second holding members. The first holding member is installed to the base to be exchangeable.

Abstract: A case, in which an inner bottom surface is formed, and a chuck tool in which a lower surface is formed are provided. The inner bottom surface is a concave surface. The lower surface is a concave surface. An elongated member chucking apparatus changes an orientation of an elongated member inside the case to a predetermined orientation with respect to the chuck tool by sandwiching the elongated member between the inner bottom surface and the lower surface. The elongated member is held by the chuck tool in the predetermined orientation.

Abstract: This fastener driving device is equipped with an impact force applying device that repeatedly applies impact forces to a fastener; and a load cell that detects a reaction force acting on the impact force applying device. The impact force applying device stops the applying of the impact force to the fastener on the basis of a detection result of the reactive force.

Abstract: In a method of fastening composite material parts, a first smoothness of a first fastener is measured which is arranged to a first countersink through-hole which is formed in a first fastened work as stacked composite material parts. A second countersink depth is determined based on the first smoothness. A second countersink through hole with a second countersink depth is formed in a second fastened work as the composite material parts. The second fastened work is fastened using the second fastener arranged to the second countersink through-hole.
