Patent EP-0526836-A2 (EP)
Inventor: ISHIKAWA TATSUYA
IPC: H04L27/233
Filed: 1992-07-29
Abstract: A QPSK modulated wave is inputted to an in- phase detector (2) and an orthogonal detector (3) which are supplied first and second frequency conversion carriers from a local oscillation unit (23). The detected components are converted to substantially a base band, and each component is digital-converted by A/D converters (6 and 7). Each digital component is spectrum-shaped by digital LPFs (8 and 9). The outputs of digital LPFs (8 and 9) are inputted to a complex multiplier (11) and calculated by use of first and second reproduction carriers and expressed as first and second calculation outputs, and inputted to a phase detector (12). The phase detector (12) obtains phase difference data between the phase expressed by the first and second calculation outputs and a predetermined phase and quadrant data of the phase. The phase difference data is used for a PLL. The PLL is formed by a filter (14), an NCO (15), data converters (16 and 17). The phase difference data is used for a AFC loop, and is inputted to a frequency error detection circuit (19) detecting a frequency error between the carrier frequency of the QPSK modulated wave and the oscillation frequency of the local oscillation unit (23). The frequency error output is smoothed by a filter (20) of an AFC loop, and used as a control signal controlling the oscillation frequency of the local oscillation unit (23). If the frequency error is large, the frequency error detection circuit (19) controls the AFC loop to be in an operation state and the PLL loop and the PLL loop to be in a fixed state. If the frequency error is small, the frequency error detection circuit (19) contains the control state of the AFC loop and switches the PLL loop to be the operation state.

Abstract: In order to easily and accurately manufacture a micromachine comprising a member which is made of a single-crystalline material and having a complicated structure, an uppermost layer (1104) of a single-crystalline Si substrate (1102) whose (100) plane is upwardly directed is irradiated with Ne atom currents from a plurality of prescribed directions, so that the crystal orientation of the uppermost layer (1104) is converted to such orientation that the (111) plane is upwardly directed. A masking member (106) is employed as a shielding member to anisotropically etch the substrate (1102) from its bottom surface, thereby forming a V-shaped groove (1112). At this time, the uppermost layer (1104) serves as an etching stopper. Thus, it is possible to easily manufacture a micromachine having a single-crystalline diaphragm having a uniform thickness. A micromachine having a complicated member such as a diagram which is made of a single-crystalline material can be easily manufactured through no junction.

Abstract: A SIMOX substrate 1 is processed through high temperature oxidation treatment after forming a mask-pattern 3 to shield specified electrodes from oxidation in order to increase partly a thickness of a buried oxide layer 2 to form an area 4. Next, after an oxide film is removed from the surface of the substrate and LOCOS separation is practiced, MOSFET is produced by fabricating a source S and a drain D on the area 4 or the buried oxide layer 2. Since the buried oxide layer corresponding to electrodes parts influenced by disadvantages of parasitic capacitance are thickened, an operation speed of an inverter is not much decreased and since mean thickness of the buried oxide layer can be thinner, a decrease of a drain electric current by negative electrical resistance can be suppressed. Furthermore, since the thickness of the buried oxide layer can be controlled in response to each device, plural devices having different breakdown voltages are formed together on the same substrate.
