Abstract: In a floating-point arithmetic unit for performing floating-point arithmetic of first and second input data which are represented by a floating-point representation and composed of first and second exponent parts and first and second mantissa parts, a shift amount calculating circuit comprises first and second subtracters (26, 27) supplied with lower (n + 1) bits of the first and the second exponent parts. The first subtracter subtracts a first lower number (#EA1) from a second lower number (#EB1) to produce a first difference signal (RS1). The second subtracter subtracts the second lower number (#EB1) from the first lower number (#EA1) to produce a second difference signal (RS1). Supplied with the first and the second exponent parts, an exponent comparing unit (28) compares the first exponent part with the second exponent part to produce a comparison result signal (CP1, CP2, CP3, CP4). Responsive to the comparison result signal, a first selector (31) selects one of the first difference signal and first and second value signals ("0", "64") as a first right-shift amount signal (SD1). Responsive to the comparison result signal, a second selector (32) selects one of the second difference signal and the first and the second value signals as a second right-shift amount signal (SD2).

Abstract: The phase ambiguity of conventional interferometers maybe removed by using two laser diodes of different optical frequency to generate a synthetic wavelength. However, the stability requirements for a two-color interferometric laser gage that must provide unambiguous determination of the optical fringe order over a large distance can be severe. The invention determines upper limits on the optical wavelength uncertainty and expresses same as a function of optical path difference between object and reference beams, phase measurement errors and the synthetic wavelength. A wavelength stabilization arrangement involves simultaneous servo control of two laser diodes (10,12) with a single Fabry-Perot etalon (36). An embodiment of the invention demonstrates its effectiveness for long-term stabilized two-color interferometry over a distance of 150 mm, with a 15 rm synthetic wavelength and a repeatability of 40 nm. For periods of less than 1000 seconds, the repeatability is eight nm.

In growing a compound semiconductor on a silicon wafer, the growth sequence such as shown in Fig. 1 is used. A necessary thin buffer layer is continuously grown at the temperature raising period up to the crystal growth temperature (Step 2). Therefore, an independent process of growing a buffer layer at a lower temperature is not necessary, and the surface morphology is also improved by this method of growing a compound semiconductor on a silicon wafer.

Abstract: An optical disk apparatus has a galvanic mirror error signal generation circuit for detecting that the galvanic mirror rotates more than an allowed limit value in directions P and Q. When it is detected by the galvanic mirror error signal generation circuit that the galvanic mirror rotates more than the allowed limit value, the light intensity of the light spot is changed from the recording-use (or erasing-use) light intensity into the reproducing-use light intensity. Accordingly, recording and erasing of information is always carried out by the projection of the light beam having a predetermined light intensity, thereby always providing a high grade of optical disk apparatus.
