Title: Data converter
Inventor: GOTO HIDEAKI
IPC: G11B20/10
Filed: 1987-09-17
Abstract: PURPOSE:To improve an error rate, by detecting a byte synchronizing signal from serial data in which the byte synchronizing signal is inserted at every data unit with an insertion cycle almost equivalent to that of the byte synchronizing signal, and converting it to parallel data of byte unit. CONSTITUTION:The serial data SD in which the byte synchronizing signal BSC of prescribed pattern is inserted at every data unit of a prescribed quantity of information is supplied to a shift register 2. When the pattern of the parallel data outputted from the register 2 coincides with that of the signal BSC, a detection signal is outputted from a pattern detection circuit 6. However, from a pulse generation circuit 8, a pulse triggered by the detection signal and also whose pulse width TD is reduced a little than the insertion cycle Ts of the signal BSC is generated, and the synchronization of a byte synchronization counter 9 is performed by the logic output of the output signal of the circuit 8 and the detection signal of the circuit 6. In such a way, it is possible to obtain the parallel data of byte unit correctly from a latch circuit 4, thereby, to improve the error rate.

Title: Measuring method of vibration mode
Inventor: KANEKO YASUTOMO
IPC: G01H3/10
Filed: 1982-12-29
Abstract: PURPOSE:To measure a vibration mode of a structure of a complicated shape by a simple method, by coating a chemical substance whose heating reaction is progressing, on the outside surface of the structure, and exciting it by a natural frequency corresponding to a vibration mode to be measured. CONSTITUTION:When a chemical substance 3 whose heating reaction is progressing, of a formula (C2H5ONa+C6H5Cl C6H5OC2H5+NaCl) is coated onto the surface of a structure 4 and excited by a natural frequency by a magnet exciting machine 6, a temperature distribution corresponding to the amplitude is formed. When it is photographed by an infrared-ray camera 5, the temperature distribution of the structure 4, namely, a vibration mode can be measured. The part whose amplitude is large becomes a high temperature since the heating reaction of the chemical substance coated onto the surface is quickened. On the other hand, the part in the vicinity of a nodal line whose amplitude is small becomes a temperature lower than that of the part whose amplitude is large because the progress of the heating reaction is slow.
