Abstract: PROBLEM TO BE SOLVED: To shield radiation noise from an amplifier and to eliminate the need of providing a complicated shielding board by making a grill of a speaker incorporating a pulse-type amplifier of punching metal board having multiple punching holes. SOLUTION: A speaker 6 has outer peripheral flanges 8, and a grill 10 is mounted on the outer peripheral flanges 8 through spacers 9.

IPC: G01N29/24
Filed: 1980-09-01
Abstract: PURPOSE:To reduce the inspector's fatigue and perform accurate flaw detection by holding the flaw detection waveform of the excitation period just before de-exciting in the non-excitation period of an electromagnet and displaying the same. CONSTITUTION:A DC electric power source 6 is controlled by an intermittent control circuit 7 to intermittently energize a DC coil 2. When a pulse generating circuit 8 supplies pulse current to a radio transmitting and receiving coil 4 while a control signal (c) is 1, ultrasonic waves propagates in a material 1 to be inspected, and the reflected ultrasonic waves from a flaw 1F and a bottom surface 1B are supplied via the coil 4 and an amplifier 12 to a cathode ray tube 13. On the other hand, when the control signals (c) goes to 0, a sweep signal generating circuit 11 stops sweeping on de-exciting of the coil 2, but the tube 13 has after-glow characteristic and the flaw detection waveform in the excitation period just before this is displayed in the tube 13. Thereby, the change in display image plane at every period of the intermittent excitation of the DC coil is obviated and the operator's fatigue is reduced.

Abstract: PURPOSE:To perform accurate detection by measuring the temperature in an adsorption layer and detecting the tip position of a mass transfer zone which develops according to the adsorption progress of a component to be adsorbed from a point of time when the measured temperature varies abruptly. CONSTITUTION:Raw material gas passes through the adsorption layer 5 in an adsorption tower and the component to be adsorbed in the raw material gas is adsorbed by the layer 5 to form the mass transfer zone 2. Adsorption heat is generated in this adsorption and sent with the gas passing through the layer 5 to raise the temperature of the downstream side of the tip of the zone 2 while the temperature of the upstream side falls. The tip part arrival of the mass transfer zone is detected accurately and excellently from abrupt variation in the temperature measured by a resistance bulb 6a provided at a specific position in the layer 5. Then the limit position arrival of the tip part of the mass transfer zone is estimated from the installation distance L of the resistance bulb 6a and the time up to the arrival and high-accuracy detection is performed through a resistance bulb 6b similarly.
