Title: Device for detecting presence or absence of powder
Inventor: ONO TOSHIO
IPC: G01F23/22
Filed: 1993-09-16
Abstract: PURPOSE:To detect the presence or absence of powder around a heat generating source and temperature sensor by detecting the radiant heat or conducted heat from a heat generating source with the temperature sensor. CONSTITUTION:The temperature of a resistance temperature sensor 2 which detects radiant heat or conducted heat from a heater 1 which is a heat generating source through a medium relies upon the medium in which the heater 1 and sensor 2 are placed. When the ambient temperature changes, the temperature of the sensor 2 changes, but, when a bridge circuit is constituted of a temperature compensating resistance temperature sensor 4 and resistors 5 and 6, the balance of the bridge circuit is not lost by the change, and the detection of the presence or absence of powder is not affected. When the case where the heater 1 and sensor 2 are placed in the air is used as a reference, it can be detected that powder exists in the circumference of the heater 1 and sensor 2 from the variation of the resistance value of the sensor 2, because the temperature of the sensor 2 changes when the heater 1 and sensor 2 are placed in the powder.

A height forward mesa 11 is formed. A buried layer 3 composed of, e.g. GaAs is grown selectively on the surface of the semiconductor substrate 1 having the mesa 11 covered with the mask 2. When a (111) B plane is revealed on the side face of the mesa 11, an ungrown depth (d) becomes maximum at a growth temperature of about 630 deg.C. Thereby, the ungrown depth (d) is reduced gradually on the high-temperature side and approaches to a certain saturation value. When the growth temperature is at 600 deg.C or lower, the ungrown depth (d) becomes nearly zero, and the side face of the mesa 11 is covered completely with the buried layer 3.
