Abstract: A compact image sensor is disclosed. This sensor comprises an insulating, imperviously sealed package, provided with a window which is transparent to light rays and is located on a front face. The inside of the package contains a stack arrangement which comprises, between the back of the package and the window, an insulating support, a set of photosensitive elements with a semiconducting substrate, surrounded by contacts. Connection terminals go through the back of the package and the insulating support. Connection means are interposed between these contacts and the ends of the terminals. The light rays are received by the photosensitive elements after they have crossed the semiconducting substrate which is thinned down beforehand. This arrangement of the photosensitive elements, the substrate and the connection means enables an appreciable increase in the area of the photosensitive surface and in the number of connection terminals, without an increase in the area of the front surface of the sensor.

Abstract: A miniature open circuit refrigerator of the Joule-Thompson type, functions as a demand cryostat by virtue of a pressure-operated refrigerant supply control. The refrigerant fluid under high pressure is introduced at a first relatively rapid flow rate into the cryostat through a calibrated opening that is fully open during the initial or start-up period of the device, for rapid cool down. This calibrated opening is thereafter at least partially closed by a valve which is urged open by a spring and which is urged closed, against the action of the spring, by a bellows containing a gas at high pressure and which is exposed on its outer side to at least a portion of the pressure of the refrigerant fluid. Upon the fall in pressure of the stored refrigerant fluid, toward the end of the start-up, the bellows expands so as at least partially to close the valve, thereby to decrease the flow of refrigerant during the final portion of the cool-down period and during the steady state or on-stream operation of the device. The invention is particularly applicable for the rapid cool down of infrared detection probes.

Abstract: The invention relates to components such as pyroelectric sensors which are particularly sensitive to piezoelectric effects and which, consequently, are disturbed by the mechanical deformations or the vibrations which the component may experience. In order to limit these disturbances, it is proposed to insert, between the chip (10) carrying the pyroelectric layer and the bottom of the package (30), a flexible sheet (42) of silicone which absorbs the deformations of the package without transmitting them to the chip. Ultrasonic bonding of the connecting wires (34) is still possible despite the presence of the flexible sheet. The chip is preferably fixed to a metallized ceramic plate (40) and abutments (44) are preferably provided at the bottom of the package in order to limit the compression of the flexible sheet (42) during the bonding operation.

Abstract: The invention uses a strip of infra-red detectors comprising a cold screen of the type that provides a constant viewing angle for all the directors in a direction that is prependicular to the axis of the strip. Two cylindrical mirrors are set at the ends of the strip and placed in the heated part of the cryostat containing the strip and the cold screen. The shape and dimensions of the mirrors as well as their positions are chosen so that the detector placed in the center of the strip detects, through reflection in two mirrors, only cold surfaces while the other detectors detect heated surfaces, through reflection in the two mirrors, in a proportion that increases with distance from the central detector of the strip, so that, along the axis of the strip, every detector has a substantially constant viewing angle. Applications: large-sized strips, for example in space applications.

Abstract: A small size e.g. 12 mm diameter by 40 mm long cryostatic device with photodetectors. A hollow finger having the photodetectors at one end is adapted to be brought to a very low temperature by a cold fluid circulating in the finger. A wall or housing surrounds finger and provides a vaccuum space surrounding the finger. A window made from a material transparent to the radiation to be detected forms part of the wall and faces the detector. The cold finger is made from a ceramic material which is either a tight ceramic or a sealed ceramic which has low thermal conductivity.

Abstract: The present invention relates to a method of and a cryogenic installation for distributing gases.From a storage tank at low pressure, successive portions of cryogenic liquid are withdrawn to an enclosure, which is isolated by closing a valve. After this, a further valve is opened, the effect of which is to cause the pressure in a receptacle to rise to the high distribution pressure and to allow the gas concerned to condense to a certain degree so that said enclosure is filled with liquid under pressure. The liquid evaporates partially at the periphery and is thus transferred to a heater and from there to a buffer container.The invention is applicable in particular to the distribution of oxygen, nitrogen and argon under pressure.
