In an air conditioning apparatus of the separate-type, an indoor unit is mounted on a wall of a room. The indoor unit is provided with an infrared ray detection unit which has an infrared ray sensor for sensing infrared rays, a temperature sensor for sensing a temperature in the detection unit, and a slit window for restricting a field of view of the detection unit. The detection unit is horizontally swung with a discharge opening of the indoor unit, from which warm or cold air is discharged, so that the room is swept by the field of view and the air. The room temperature distribution is obtained from the output signal from the detection unit and, the amount of the discharged air directed to the respective areas of the room is adjusted in accordance with the room temperature distribution.

A temperature detecting device detects infrared rays from an object to be measured and determines the temperature of the object based on the detection result. To avoid the influence of contamination adhered to the infrared ray incident surface of an infrared ray detecting unit, a correction coefficient for the detection result of the infrared ray detecting unit is determined before actual temperature detecting starts. For this purpose, the infrared rays fed from the object into the infrared ray detecting unit are interrupted by a shutter device. The infrared ray detecting unit detects the infrared rays fed from the shutter device through the infrared ray incident surface, and it outputs a first detection value corresponding to the shutter temperature. A shutter temperature detecting element directly detects the actual temperature of the shutter device, and it outputs a second detection value corresponding to the actual temperature of the shutter device. The correction coefficient is determined by comparing the second detection value from the shutter temperature detecting element with the first detection value from the infrared ray detecting unit. Subsequently detected temperatures are then corrected by this correction coefficient.

In a quadrupole mass spectrometer which measures partial pressure strength according to a gas type in a vacuum system from ion current intensity, a quadrupole mass spectrometer with a total pressure measurement electrode has a total pressure measurement electrode for examining an ion density disposed in a demarcation space which is comprised of a grid electrode and an ion focusing electrode. And, a vacuum system is provided with only the quadrupole mass spectrometer which measures partial pressure strength according to a gas type in the vacuum system from an ion current intensity and does not have an ionization vacuum gauge other than the quadrupole mass spectrometer.

The present invention relates to a manufacturing method of a material for vacuum device used in a vacuum apparatus that generates ultra-high vacuum and performs processing. Its constitution has the steps of: reducing pressure around the alloy of Cu and a doping element; increasing the temperature of the alloy to outgas hydrogen from the alloy, and gathering the doping element near the surface of the alloy and precipitating the doping element; and exposing the alloy to single oxygen, single nitrogen, mixed gas of oxygen and nitrogen, ozone (O3), oxygen content compound, nitrogen content compound or oxygen-nitrogen content compound, or a combination of them, or a plasma thereof while the temperature of the alloy is maintained at a range of room temperature or higher and the temperature of the alloy increased for outgassing hydrogen or lower, whereby it is reacted with the precipitated doping element so that one of an oxide film, a nitride film and an oxide-nitride film of the doping element is formed on a surface layer of the alloy.

In an optical system for an oblique incidence interferometer, first and second prisms are used for luminous flux dividing and for luminous flux combining, respectively. Reference light and measurement light are separated from each other at a surface where collimated coherent light enters or exits from the first prism, whereas the reference light and measurement light are combined together at a surface where the measurement light enters or exits from the second prism.
摘要:
A semiconductor device has an interconnection pattern that crosses a vertical step. The part of the vertical step crossed by the interconnection pattern includes a horizontal side-step. The horizontal side-step increases the total length of the crossing, thereby reducing the risk of electrical discontinuity at the crossing, without increasing the width of the interconnection pattern itself.

A fluid cylinder assembly of the kind provided with a cylinder tube in which a piston coupled by a piston rod operates. The cylinder tube has one end connected with a rod cover. The piston rod passes through an aperture in the rod cover and projects outwardly. The rod cover is associated with means for mounting the fluid cylinder assembly on a frame and a load transducer which converts a change in load axially acting thereon to a change in voltage or current and develops an electric signal. The movement of a lead wire extending outwardly of the load transducer is precluded, and the results of measurement are obtained with a high degree of accuracy.

摘要:
A cutting and dust collecting housing which encloses a cutter main shaft and a cutter forms a closed space where cutting, cooling and chip collecting are performed. The pressurized cold air introduced into the housing, partly is blown from first cold air outlet holes to make an air curtain around the cutter, and partly is blown from second cold air outlet holes to cool the cutter and at the same time to strip cutting chips off the cutter. The cutting chips are floated in the housing and then discharged therefrom by a vacuum type cutting chip sucking device.
