In an inkjet printing apparatus capable of automatic duplex printing, time required to fix ink is shortened and throughput is improved without producing uneven fixing. The inkjet printing apparatus includes a printing unit that prints onto a sheet, a fixing unit that heats a sheet printed by the printing unit, a conveying unit that conveys a sheet with respect to the printing unit and the fixing unit, and a controller that controls the conveying unit such that a printing region of a sheet printed on the first side by the printing unit passes through the fixing unit, and afterwards, the conveyance direction of the sheet is reversed in order to print on the second side and the printing region once again passes through the fixing unit. The controller variably controls the conveyance speed of the sheet when the printing region once again passes through the fixing unit.

A solar simulator having improved measurement precision, including an array of light emitters having point light emitters planarly arranged in a given range, an effective irradiated region spaced apart from a surface having the array thereon, and a portion which absorbs at least a part of light from a direction which passes through a gap between the individual point light emitters. In a preferred aspect, the light absorption portion includes an absorption surface disposed in at least a part of the gaps between the light emitters. In another preferred aspect, a translucent board holds the light emitters and has a translucent portion corresponding to at least a part of the gaps between the light emitters, and an absorption layer at a position for absorbing light from the direction which passes through the translucent portion.

A solar simulator in which locational unevenness of irradiance is reduced by using a small and simple optical system, having an array of light emitters 2 with a plurality of point light emitters planarly arranged in a given range 24, an effective irradiated region 4 spaced apart from a surface having the point light emitters 26 arranged thereon, and a reflection mirror 6 disposed to surround the given range 24 of the array. Preferably, a distance L between the point light emitter positioned at the outermost portion of given range 24 of the array of light emitters 2 and a light-reflecting surface of the reflection mirror is half of a pitch a of the array of the point light emitters and, more preferably, the distance L is larger than half of a width b of each point light emitter, and smaller than half of the pitch a.

A refrigerating machine includes a compressor for compressing a refrigerant, a radiator for radiating heat from the refrigerant discharged from the compressor, an expander for expanding the refrigerant discharged from the radiator, and an evaporator for evaporating the refrigerant discharged from the expander, all connected in series. The refrigerating machine also includes a refrigerant flow regulator for regulating the amount of refrigerant flowing into the expander and a controller for controlling the compressor and the refrigerant flow regulator. When the compressor is stopped, the controller controls the refrigerant flow regulator to reduce the amount of refrigerant flowing into the expander.

The present invention provides a heat pump including: a compressor; a radiator; a first throttling device having a variable opening; an expander; a second throttling device having a variable opening; an evaporator; piping that connects the compressor, the radiator, the first throttling device, the expander, the second throttling device, and the evaporator so that refrigerant circulates thorough the elements in that order; and a control device for controlling the opening of the first throttling device and the opening of the second throttling device. This heat pump is capable of independently controlling the pressure of the refrigerant flowing into the expander (intermediate pressure) and pressure in a high-pressure side of a refrigeration cycle, and also is capable of size reduction, or in some cases elimination, of a receiver for the refrigerant.

A vacuum processing apparatus is constituted of the following portions: a processing container with the bottom, capable of drawing vacuum; a placement platform installed in the container; a heating portion for heating a substrate on the platform; a processing gas-feeding portion for feeding a processing gas into the container; a partitioning portion surrounding a space between the platform and the bottom of the container and partitioning off the space from a processing space in the container; a purge gas-feeding portion for feeding a purge gas into the space surrounded by the partitioning portion; a purge gas-discharging portion for discharging the purge gas from the space surrounded by the partitioning portion; a control portion for controlling the purge gas-feeding portion and/or the purge gas-discharging portion so as to regulate the pressure in the space surrounded by the partitioning portion; and a temperature-detecting portion penetrating the bottom of the container, inserted in the space surrounded by the partitioning portion, and having the top end in contact with the platform. The partitioning portion has the lower end in surface-contact with the bottom of the container. The control portion regulates the pressure in the space surrounded by the partitioning portion to a pressure higher than that in the processing space in the container.
