Abstract: When a refrigerant amount balance control is executed, in indoor units where the refrigerant supercooling degree is lower than an average refrigerant supercooling degree, the refrigerant pressure on a downstream side of indoor expansion valves decreases since the degrees of opening of the valves are decreased. On the other hand, in an indoor unit where the refrigerant supercooling degree is higher than the average refrigerant supercooling degree, although the degrees of opening of the valves are made high, the refrigerant pressure on the downstream side of the valves decreases and this decreases the refrigerant pressure on the downstream side of the indoor expansion valve, so that the difference in pressure between on the upstream side and on the downstream side of the indoor expansion valve increases and the liquid refrigerant staying at an indoor heat exchanger of the indoor unit consequently flows out into a liquid pipe.

Abstract: An unevenness inspection system includes an image pickup section configured to acquire a picked-up image of an inspection target, an image generation section configured to generate a color-unevenness inspection image and a luminance-unevenness inspection image, based on the picked-up image, a calculation section configured to use both of the color-unevenness inspection image and the luminance-unevenness inspection image to calculate an evaluation parameter, and an inspection section configured to use the calculated evaluation parameter to perform unevenness inspection. The image generation section generates the color-unevenness inspection image and the luminance-unevenness inspection image, based on a filter-processed color-component image and a filter-processed luminance-component image. The calculation section calculates the evaluation parameter in consideration of unevenness visibility with respect to both of color and luminance.

Abstract: An apparatus for producing a semi-solidified metal has a heating device which heats a metal material, a vessel, a cooling device which cools the vessel, and a pouring device which pours the metal material into the vessel. The vessel has a hollow member which configures a wall of the vessel and is opened at both of the upper and lower ends and into which the metal material is poured from the upper opening, and a bottom member which closes the lower opening of the hollow member and configures the bottom of the vessel. The cooling speed of the metal material by the bottom member is faster than the cooling speed of the metal material by the hollow member.

Abstract: A bridgeless power factor improvement converter is configured with input terminals for an AC voltage, output terminals from for a DC output voltage, diodes, first through fourth switches, and coils. A control circuit selectively switches the first through fourth switches according to the AC voltage, a first dead time period (the third switch OFF/the fourth switch ON) in which the first and second switches are in a dead time including a zero-cross point from a positive period to a negative period, and a second dead time period (the third switch ON/the fourth switch OFF) in which the first and second switches are in the dead time including the zero-cross point from the negative period to the positive period. The control circuit maintains the third and fourth switches in the OFF state during a period other than the first and second dead periods.

Abstract: A picking system enables a user to easily know when an article that has been placed is different from an article originally scheduled to be placed in a particular position. The picking system includes a picking robot, an ID reader, an encoder, a comparing unit, and a terminal screen. The picking robot picks a workpiece from a first predetermined position and places the article in a second predetermined position. The ID reader acquires identification information of the workpiece picked by the picking robot. The comparing unit compares the identification information acquired by the ID reader with identification information of a workpiece scheduled to be picked. The terminal screen indicates, based on a result of the comparison executed by the comparing unit, a placement position of a workpiece whose identification information does not match the identification information of the workpiece scheduled to be picked.
