Title: Non-destructive inspecting device
Inventor: FUJIMOTO MINORU
IPC: G01N27/90
Filed: 1981-03-02
Abstract: PURPOSE:To discriminate and detect internal defects and surface defects by generating ultrasonic wave and eddy current to a material to be examined by means of one electromagnetic probe, and detecting the eddy current. CONSTITUTION:In the case of detecting internal defects, selection switches 10, 11 are connected to the side (a), and a DC electric power source 7 is controlled to energize a DC coil 2, thereby applying a DC magnetic field to a material 1 to be examined. If pulse currents are applied to energizing coils 4A, 4B from a pulse generating circuit 8 in such a state, eddy current is generated in the surface of the material 1, and the ultrasonic waves in accordance with change strains are generated in the material 1. Since the reflection waves of the ultrasonic waves act upon the eddy current in the surface of the material to be examined, this eddy current is detected with detection coils 5A, 5B. In the case of detecting surface defects, the switches 10, 11 are connected to the side (b) to stop the excitation of the coil 2 and the coils 4A, 4B are energized by oscillating an oscillation circuit 12. The eddy current in accordance with this excitation is detected with the coils 5A, 5B.

Abstract: PURPOSE: To efficiently obtain the subject compound, good in acid and salt resistances and solubility and useful for a hydrophilic emulsifying agent, etc., by reacting and esterifying a ketalized sucrose with a fatty acid in the presence of an esterifying enzyme and then hydrolyzing the ketalized part. CONSTITUTION: 2-Methoxypropene, etc., are added to ketalize sucrose in the presence of p-toluenesulfonic acid in N,N-dimethylformamide to provide a sucrose ketal (e.g. 4,6-O-isopropylidenesucrose). An enzyme capable of catalyzing the esterification of hydroxyl groups in the sucrose ketal (e.g. a lipase derived from Mucor miehei) is then reacted with the resultant sucrose ketal and a fatty acid (e.g. myristic acid) to produce a sucrose ketal ester of the fatty acid. The ketal moiety of the prepared sucrose ketal ester of the fatty acid is subsequently hydrolyzed to efficiently afford the objective sucrose ester of the fatty acid, excellent in acid and salt resistances and solubility and useful as a hydrophilic emulsifying agent, etc.

Abstract: PURPOSE:To prevent malfunction and improve weak electric field color sensitivity at the time of receiving normal SECAM signal by discriminating automatically whether input radio waves are PAL signal or SECAM signal by color killer voltage of a PAL color demodulation circuit. CONSTITUTION:A PAL burst sampling detection/ACC feedback amplifier 2 samples only burst signal of PAL signal and detects this by 4.43MHz carrier (d) which is an output signal of a voltage control oscillator 8, and DC smooths this to obtain a signal (b). When this signal (b) is higher than reference voltage, a PAL circuit color killer signal (g), output of the circuit 11, becomes ''high'' and becomes discriminating output indicating that it is color. Consequently, killer switches 12, 13 become on and a PAL-R-Y demodulation signal (e), and a PAL- B-Y demodulation signal (f) are obtained. Further, the signal (g) changes change- over switches 22, 23 to PAL side. Accordingly, the PAL-R-Y signal (e) is outputted from an output terminal (l) and the PAL-B-Y signal (f) is outputted from an output terminal (m).
