摘要:
The present invention realizes a new actuated valve type water flow detection device that can be applied to a pipe with a relatively large bore diameter. The water flow detection device A includes a coil spring for urging a detection rod in an opening direction of a valve body. Therefore, while detecting water flow by linking a rotation of the detection rod to a rotation of the valve body when the valve body opens or closes by a differential pressure, the detection rod does not apply a closing load to the valve body that is released. Therefore, even when the rotation of the valve body is small because the water flow in the secondary side is small in a conventional actuated valve type water flow detection device, it is possible to increase an opening angle of the valve body.

The glue application unit comprises side glue application members which have a pair of scrapers (7, 7) and can engage with the back margins (s) of the book block (P). The scrapers consist of elastic rod-like bodies (7a) and scraping portions (7b) provided at leading ends of the bodies. The scrapers obliquely extending in a direction of movement of the book block from the outside of the path of the downwardly protruding portion of the book block into the path in such a way that the scrapers contact each other in an inverted V shaped configuration. The scraping portions engage with the back margins of the book block by the elastic biasing of the bodies while the downwardly protruding portion of the book block passes between the scrapers.

A machine for attachment of a cover to a book block comprises a press plate elevating mechanism for elevating a press plate 8, a nip plate drive mechanism for sliding nip plates 9 and 10, and a controller 30 controlling the press plate elevating mechanism and the nip plate drive mechanism. The press plate 8 elevates from the lower standby position to an upper press position. The press plate 8 presses the cover 12 to the book block 4 at the upper press position. The cover 12 is attached to the book block 4 by pressing the cover 12 to the lower end surface of the book block 4. The press plate 8 is elevated from the intermediate position to the upper press position, staying at the intermediate position during a waiting time for adjustment. The press plate 8 elevates from the intermediate position to the upper press position.

A sheet feeding machine comprises a housing 1, a feed section for feeding a plurality of sheets 40 in a feed direction 11, and a detecting section 3 having detector 30, 31 for detecting information 41, 42 printed on the sheet 40. The detecting section 3 comprises a support frame 32 for supporting the detector 30, 31, a guide rail 33 mounted on the support frame 32 and extending for guiding the detector 30, 31, and a guide mechanism 35 arranged between the housing 1 and the support frame 32 for guiding the support frame 32. The support frame 32 can be accommodated in the housing 1 when detecting the information 41, 42 of the sheet 40. The support frame 32 can be drawn out of the housing 1 when moving the detector 30, 31 along the guide rail 33.

An ultrasonic transducer incorporated into an ultrasonic inspection apparatus for examining existence of defect in a sample dipped in water comprises a transducer main part having an oscillator which projects an ultrasonic wave to the sample, receives the reflected wave from the sample and outputs the received reflected wave as an echo signal, a transmitter substrate producing a drive pulse for emitting the ultrasonic wave to the oscillator, a receiver substrate for amplifying the echo signal, a housing for containing therein both substrates electrically connected, and connecting member for electrically connecting between a signal input/output terminal and the side of the oscillator in the transducer main part, wherein, when a maximum operational frequency of the ultrasonic wave emitted from the oscillator is referred to as fmax [MHz], the connecting member is set at a length of 100/fmax [cm] or less. Even if the sample to be examined is small, a desirable defect inspection can be achieved at an excellent examination accuracy.

When carrying workpieces from a loading area in which the workpieces are handled into a heat treatment furnace to make the workpieces subjected to a heat treatment process using a predetermined process gas, the loading area is evacuated and controlled at a predetermined low negative pressure. An exhaust for evacuating the loading area is connected to the loading area, and a controller controls the exhaust so that the loading area is maintained at the predetermined low negative pressure. A specific gas and particles contained in a gas discharged from the loading area are removed by filters.
