Abstract: PURPOSE:To enlarge the caliber of an infrared emitting port and that of an infrared receiving port and to reduce running cost, by recirculating heat resistant gas across the emitting port and receiving port provided to a heat insulating wall. CONSTITUTION:CO2 laser is used as an infrared emitting element 1 and an infrared detector comprising a HgCdTe compound semiconductor is used as an infrared detec tion element 2 and both elements are surrounded by a heat insulating wall 9 while an object 4 is irradiated with infrared rays from the infrared emitting element 1 through the infrared emitting port 3 formed to a part of the heat insulating wall 9 and the reflected waves from the object 4 are received by the infrared receiving port 6 formed to a part of the heat insulating wall 9 to be detected by the infrared detection element 2. At this time, the heat resistant gas from a heat resistant gas generator 11 is cooled by a cooling device 10 to be introduced into the receiving port 6 and the emitting port 3 by a fan 8 to absorb heat energy receiving from high temp. environment 5 and subsequently passes through a recirculation path 20 to be recovered for re-utilization by the heat resistant gas generator 11. By such a construction, the caliber of the emitting port and the receiving port can be enlarged. Besides, since heat resistant gas is recirculated, running cost reduces.

Title: Dry etching method
Inventor: KASE MASA
IPC: H01L21/3065
Filed: 1988-02-29
Abstract: PURPOSE:To make the depths of trenches equal and to shorten etching time, by reducing the pressure of reacting gas before the aspect ratio of the trench having the minimum width in a mask pattern becomes a value at which an etching speed is decreased. CONSTITUTION:A silicon oxide film 2 on a silicon substrate 1 is etched, and a mask pattern 3 is formed. With the pattern as a mask, etching is performed. When the ratios between pattern widths W1 and W2 and trench depths D1 and D2, i.e., the aspect ratios, exceed a specified value, the etching speed is de creased. The lower the pressure of reacting gas is, the larger will be the value of the speed reduction. Therefore, the pressure of the reacting gas is deceased before the aspect ratio of the trench having the minimum width in the pattern 3 reaches the value at which the etching speed is deceased. The procedure is repeated step by step, and the etching is performed. Thus, the depth of the trench can be made equal regardless of the width of the pattern, and the etching pattern is shortened.

After the TiSi has crystallized and becomes C54 , the temperature of the furnace is decreased to about 800 deg.C in about 20-30 minutes. At this time, the wafer is taken out of the furnace and coolded naturally at the room temperature thereafter.

IPC: G01R33/04
Filed: 1988-02-26
Abstract: PURPOSE:To accurately measure an external magnetic field by measuring the time difference of a signal generated on detection winding while an external magnetic field is applied to 1st and 2nd magnetic cores. CONSTITUTION:A power source 14 supplies a triangular wave exciting current to exciting winding 14 to produce pieces phi1 and phi2 of magnetic flux of the same intensity in mutually opposite directions at the 1st and 2nd magnetic core parts 11 and 12 so that they reach a magnetic saturation level intermittently. At this time, when no external magnetic field is applied to the magnetic core parts, the magnetic core parts 11 and 12 enter magnetic saturation states at the same timing and when a measuring means 18 measures no difference in output time, it is judged that the external magnetic field is at 0 level. When an external magnetic field He is applied to the magnetic core parts 11 and 12, on the other hand, the magnetic flux increases at the magnetic core part 12 and the timing of magnetic saturation is advanced; and the magnetic flux decreases at the magnetic core part 11 and the timing of the magnetic saturation is delayed. The means 18 measures the difference in output time between 1st and 2nd voltage signals to know the intensity of the external magnetic field.
