Abstract: A comfort-analyzing device includes a display unit, a first control unit, an input unit, and a cognitive-structure constructing unit. The display unit is configured to present a questionnaire for extracting both a comfort level of a user in an environment and at least one environmental factor to determine the comfort level. The first control unit is configured to cause the display unit to present the questionnaire twice or more during a survey period. The input unit is configured to accept, from the user, input of each reply to the questionnaire presented twice or more. The cognitive-structure constructing unit is configured to construct a cognitive-structure model representing a cognitive structure of the user regarding comfort by extracting both the comfort level and the at least one environmental factor in chronological order based on each reply to the questionnaire presented twice or more.

Abstract: An ozone treatment apparatus includes: an ozone gas generator that generates ozone gas from raw material gas; a sludge pump that pressurizes sludge to be treated; an ejector in which the sludge to be treated, which is pressurized by the sludge pump, is injected; and a valve provided between the ozone gas generator and the ejector. The valve becomes in an open state when pressure on the former stage side is larger than pressure on the latter stage side by a specified value or higher. An ozone gas storage facility may be provided between the ozone gas generator and the valve. A sludge mixing tank installed in the latter stage of the ejector and a sludge circulation pump that connects an upper part of the sludge mixing tank and the latter stage of the sludge pump may be provided.

Abstract: In a water treatment apparatus, a tilted plate is disposed at an incline relative to a horizontal plane. Water to be treated is passed over the upper surface of the tilted plate. A discharge forming body is disposed across a gas layer above a water film formed by the water to be treated flowing over the tilted plate. A droplet forming apparatus exerts power on the water film so that at least some of the water to be treated shoots upward in the form of droplets.

Abstract: In an eddy current testing method which involves using a rotatable eddy current testing probe in which a detection coil is arranged within an exciting coil, a change in detection sensitivity (a deviation of detection sensitivity) which changes depending on the rotational position of the detection coil is reduced. The eddy current testing probe includes an exciting coil EC1, a detection coil DC1, an exciting coil EC2 and a detection coil DC2, which are mounted on a disk DS. The eddy current testing probe is placed so as to face a circumferential surface of an object to be inspected T, which is in the shape of a circular cylinder, and the disk DS is rotated. Then, the distance (liftoff) between the detection coils DC1 and DC2 and an inspection surface changes. Therefore, also the detection sensitivity to a flaw signal changes. To reduce the change in detection sensitivity, the detection sensitivity is adjusted by detecting the rotational position (rotational angle) of the detection coils DC1 and DC2.

Abstract: A rotary eddy current flaw detection probe device has a plurality of ?-shaped eddy current flaw detection probes attached in a rotating disc for detecting flaws in all directions regardless of the flaw direction. Four ?-shaped eddy current testing probes P11 to P22 are arranged around the rotation center Ds1 of a rotating disc 111 and are embedded in the disc 111. The coil planes of detector coils Ds11 to Ds22 of the testing probes P11 to P22 are parallel with each other, and are perpendicular to the rotation plane of the rotating disc 111. The coil planes of the detector coils incline at an angle ? relative to a line Y passing through the centers Ps11 and Ps12 of the probes P11 and P12. The detector coils Dc11 and Dc12 are cumulatively connected to each other and the detector coils Dc21 and Dc22 are differentially connected to each other.

Abstract: For the purpose of preventing a decompression passageway in a two-cycle engine from being blocked by carbon soot, facilitating manufacture of a two-cycle engine having decompression structure and eliminating reduction of output power of the two-cycle engine caused by the decompression structure, a known two-cycle engine includes a scavenging passageway formed along an inner wall of a cylinder. The scavenging passageway is directed in the axial direction of the cylinder and communicates with a crank case of the engine. A decompression groove extends in the axial direction of the cylinder on the upstream side of a cylinder cooling airflow at a top end portion of the scavenging passageway. The width and depth of the decompression groove are either varied along the axial direction of the groove so as to be narrowed towards a tip end thereof directed toward a plug, or are provided with a narrowed portion of venturi shape.
