摘要： PURPOSE:To improve the accuracy of inspection and to perform fast on-line inspection by deciding whether or not a flange part has a defect based on the signal of a rotary probe unit which rotates along the flange part of a can. CONSTITUTION:The rotary probe unit 39 moves synchronously in opposition to the flange part of the can 15 which revolves while being held by a can revolving mechanism, and also revolves along the flange part, so that the unit 39 inspects the defect of the flange part of the can 15. Then the output signal of the unit 39 is inputted to a self-diagnostic circuit 65 through an head amplifier 48, a time-division multiplex circuit 60, a defect signal sampling circuit 63, etc. A circuit 65 monitors respective output signal voltages and outputs a warning signal to a decision circuit 66 when an abnormal voltage is generated. The circuit 66 outputs an indication signal to a sequencer which is not shown in a figure when the voltage of a defect signal outputted by the circuit 64 exceeds a prescribed value to discharge the defective can, and then fast on-line inspection is enabled; and the unit 39 can be adjusted in detection sensitivity individually, so the inspection accuracy is improved.

摘要： PURPOSE:To form the titled Al-alloy sheet metal improved in strength, by adding precipitation hardening treatment between the rapid heating-cooling and final cold rolling stages in the conventional method at the time of manufacturing an Al-alloy sheet metal having a specific composition. CONSTITUTION:An Al-alloy ingot consisting of, by weight, 0.5-1.5% Mn, 1-2% Mg, 0.2-0.5% Si, 0.2-0.4% Cu, and the balance Al with inevitable impurities is subjected to homogenizing treatment and then to hot rolling to be formed into a hot-rolled plate. This hot-rolled plate is subjected to primary cold rolling at >=40% draft and then to rapid heating-cooling treatment consisting of rapid heating at 500-600 deg.C and immediate cooling down to room temp. which is further subjected to secondary cold rolling at 10-45% draft and then to holding at 100-200 deg.C for 0.5-8hr to undergo precipitation hardening treatment. Subsequently, the above sheet is subjected to final cold rolling at >=10% draft, and further, the total draft of secondary cold rolling and final cold rolling is regulated to 50-75% and, finally, the above sheet is held at 150-250 deg.C, for 5-50min to undergo heat treatment. In this way, the Al-alloy sheet metal having high strength and excellent in deep drawability, ironing, bulge formability can be obtained.

摘要： PURPOSE:To heat a beverage in a can in a short time by moving a holding part to hold the can to a heat insulating container having heating medium with an elevating/vibrating means, immersing it into the heating medium, and vibrating it. CONSTITUTION:When an aluminum can A drops to a holding part 8, an elevating table 25 descends by a motor 36, and the holding part 8 descends through a rod 7 together with the can A, it is immersed into water W in an heat insulating container 1, and simultaneously a cover 13 is closed. On the other hand, a heater 2 is controlled so as to hold the temperature of the water W to be constant. Next, a sliding part 31 reciprocatingly moves in a horizontal direction through an eccentric pin 29 and coupling rod 30 by a motor 27. Then, the rod 7 rocks with a spherical surface bush 23 as a fulcrum, and thus, the holding part 8 and the can A rock approximately in the horizontal direction. After the can A vibrates for a time necessary for arriving at a constant temperature, it elevates from the water W together with the holding part 8, water droplets are eliminated by the air of an air blowout nozzle 15, the cover 13 is opened, and the container 1 is taken out outside.

摘要： PURPOSE:To continuously supply liquefied gas to a filling line where a liquefied gas cylinder can not be carried-in, by providing a pressure control means and a liquid level detector to the upper and lower chambers of a heat insulating liquefied gas container and controlling an opening and closing valve and a valve mechanism on the basis of a liquid level signal. CONSTITUTION:A solenoid valve 33 is operated by the detection signal of the first liquid level detector 44 and the liquid level of the liquid nitrogen in an upper chamber 31a is held within a set range and, when pressure is judged to be high by an upper chamber pressure detector 46, a solenoid valve 47 is opened and, when said pressure is low, a solenoid valve 48 and a self-supporting type pressure control valve 49 are opened. A solenoid valve 52 is controlled by the second liquid level detector 51 in a lower chamber 31b to hold a liquid level within a set range. When pressure is judged to be high by a lower chamber pressure detector 54, a solenoid valve 56 or a pressure control valve 55 is operated so as to be opened and, when said pressure is low, a pressure control valve 57 for pressurization is opened to introduce the nitrogen gas of the outside. A definite amount of the nitrogen gas is always introduced under pressure from the pressure control valve 57 and pressure variation or the reduction and change in the pressure of the lower chamber 31b at the time of lowering in a liquid level is corrected to keep the pressure in the lower chamber 31b constant.

摘要： PURPOSE:To obtain a defective signal with a good S/N by removing noise components through a BPF which varies a flaw detection signal according to a revolving speed when the flaw detection signal is transmitted from a rotary side to a fixed side through a slip ring. CONSTITUTION:When the flaw detection signal is transmitted from the rotary side to the fixed side through the slip ring, a pulse train S1 from a precedent- stage time-division multiplex receiving circuit is inputted to an F/V converter 61 and converted into a voltage. Then, an integrating circuit 62 integrates a voltage within a constant time and averages it, and the voltage-controlled BPF63 is controlled with the averaged voltage to remove noise components from the flaw detection signal SI, thereby obtaining the defect inspection signal SO with the good S/N.

摘要： PURPOSE:To improve the accuracy of detection by rotating a rotary detection part along a body to be inspected, and passing a flaw detection signal obtained by a flaw detection probe smoothly to a fixed part side by a rotary transformer. CONSTITUTION:A rotary side coil 28 is wound spirally around the base end of a spindle 20d and a signal line is wired from the flaw detection probe 20a to the coil 28 through a passage 20p. A fixed-side coil 29 is fixed to an outside cylinder 20n through a coil support base 20q and arranged at the outer periphery of the coil 28 while a constant clearance is left. Both coils 28 and 29 constitute the rotary transformer 30 which leads the signal of the probe 20a out to the fixed side. The flaw detection signal from the probe 20a is guided and transmitted to the fixed part by the transformer 30 and passed smoothly, so the flaw detection signal is securely led out, thereby improving the inspection accuracy.
