Abstract: Provided are an ultrasonic testing probe and an ultrasonic testing apparatus capable of reducing the time required for flaw detection while maintaining the flaw-detection capability, irrespective of the shape of the inner surface of a tested object. A first probe (21) and a second probe (22) are provided, in each of which a plurality of oscillators that transmit ultrasonic waves to a tested object (T) and detect the ultrasonic waves reflected from the tested object (T) are arrayed. The first probe (21) is disposed closer to a flaw in the tested object (T) than the second probe (22) is. The first probe (21) generates longitudinal ultrasonic waves that propagate on an inner surface (T5) of the tested object (T) opposite to an outer surface (T2) thereof where the first probe (21) and the second probe (22) are disposed and transverse ultrasonic waves that propagate from the outer surface (T2) toward an inside of the tested object (T).

Abstract: Deflection (bend) in the length direction due to a difference in the heat expansion between two plate-like members, between which rows of heat transfer tubes are sandwiched, is reduced, and deflection (bend) of rows of heat transfer tubes is prevented. Two long plate-like members, in which a plurality of cutouts along the longitudinal direction are provided in one side the widthwise direction, are provided, and each of the cutouts includes two rectilinear sections that extend in a direction perpendicular to the longitudinal direction axis of the plate-like members, and a semicircular section that links one end of the rectilinear sections together. The distance between the two rectilinear sections along the lengthwise direction axis of the plate-like members and the diameter of the semicircular section is set so as to be greater than the diameter of the heat transfer tubes that are contained within the cutouts.

Abstract: A tube flaw detecting method detects a flaw portion in a heat exchanger tube constituting a boiler furnace wall using two probes, enabling one to carry out appropriate inspection work with a high efficiency. A transmitter probe and a receiver probe are juxtaposed in a circumferential direction, and an ultrasonic wave is transmitted from the transmitter probe to propagate. Repeated reflections occur at a tube inner surface and tube outer surface, and the wave is reflected at a crack extending in the circumferential direction to return, propagating likewise to be received by the receiver probe so that existence of the crack is confirmed. Thus, inspection work for a crack can be done with certainty with a simple arrangement.

Abstract: In a method and apparatus for continoulsy producing a heated roll-shaped food, a horizontal type of cylindrical or bell-shaped heating drum is rotated and heated while coated with a scorch-retarding oil film on the inner peripheral surface thereof and raw material is poured onto the inner peripheral surface thereof. The raw material is heated while spreading out on the inner peripheral surface of the heating drum with aid of fluidity of the raw material and the rotation of the drum. The heated raw material swells up along the inner peripheral surface of the heating drum, and is exfoliated from the inner peripheral surface due to its weight and reversed at a head edge portion thereof.

It comprises the step of feeding to a twin-screw extruder at least one of the following materials; the material prepared by heat-treatment of the "surimi", the material prepared by addition and mixing of suitable subordinate raw material to and into the "surimi" and subsequent heat-treatment of the resulting mixture, the material prepared by drying, for dehydration, of the "surimi" to make the water content thereof not greater than 70% and the material prepared by gelation of the "surimi" through the setting of the same. It further comprises the steps of treating the at least one material under pressures of 1 to 50 kg/cm.sup.2 and temperatures of 100.degree. to 200.degree. C., by means of the twin-screw extruder, thereby processing it into a texturized material.
