Abstract: PURPOSE:To reduce etch-pit density, and improve the crystallizability of a III-V compound semiconductor layer, by interposing a substratum layer of GaP or AlAs or AlP between a silicon substrate and the compound semiconductor layer. CONSTITUTION:A substratum layer of GaP or AlAs or AlP is formed on a silicon substrate 10, and III-V compound semiconductor layers 12, 13 are formed on the layer 11. The lattice constants and the coefficient of linear expansion of the substratum layer of GaP or AlAs or AlP take the values between silicon and the III-V compound semiconductor. Hence misfit dislocation on the interface between the silicon substrate and the substratum layer of GaP or AlAs or AlP is reduced. Thereby etch-pit density is reduced, and the III-V semiconductor layer having excellent crystallizability can be grown on a silicon substrate.

IPC: G01R29/08
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a means to perform accurately and easily the measurement of magnetic field generated by the pins of an IC. SOLUTION: A very small shielded loop probe 12 is incorporated inside an IC socket 11 near its terminal. An IC 14 is fitted in the IC socket 11 and operated by an external signal and an external power supply, and thereby a magnetic field is generated near the terminal by a high frequency current flowing through the terminal of the IC 14. The generated magnetic field allows determining the high frequency current flowing through the terminal. Thus an accurate and easy determination of high frequency current can be established, and effective EMI (emission of unnecessary electromagnetic fields) countermeasure can be performed.

Abstract: PROBLEM TO BE SOLVED: To provide a dehumidifier which enables dehumidification at a low temperature and at a low humidity by preventing frosting and freezing of a cooler even in the setting of a low temperature and also achieves a lower cost, a less weight and a smaller size. SOLUTION: Highly moistened air (a) is drawn into an air passage system 6 by a fan 15 at a suction port 4 of a mechanical frame 2. In the air passage system 6, the highly moistened air (a) is heated by a first internal condenser 7 and then, cooled down by a cooler 8. Then, the air is turned into a room from a blowing port 5 of the mechanical frame 2. On the other hand, a refrigerant always flows into the first internal condenser 7. As a result, even under an excessively cooled condition caused by the cooler 8 when the detected temperature of a thermostat 14 exceeds a set value, frost and ice adhering to the cooler 8 is melted by heat of the highly moistened air (a) heated by the first internal condenser 7 while it passes through the cooler 8.
