摘要:
A hot flaw detector is equipped with a sensor holding member that has a circular opening through which the material to be inspected will pass and that holds a flaw detecting sensor. Provision is made of an annular cooling liquid injection port that is open at an end of the sensor holding member adjacent to the inner peripheral wall of the circular opening, and provision is further made of an annular cooling liquid introduction port that is open at the other end of the sensor holding member adjacent to the inner peripheral wall of the circular opening. The cooling liquid is injected from the annular cooling liquid injection port, and forms a liquid film along the inner peripheral wall of the circular opening, and is recovered through the annular cooling liquid introduction port. The inner peripheral wall of the sensor holding member is effectively cooled by the liquid film which drips little onto the material to be inspected.

A power supply device which supplies power through a power supply line to a device, the power supply device including a first voltage generation unit which generates first DC voltage and supplies the first DC voltage to the power supply line, a second voltage generation unit which generates second DC voltage that is lower than the first DC voltage and supplies the second DC voltage to the power supply line; and a control unit which stops the power supply by the second voltage to the power supply line and causes the power supply by the first voltage to the power supply line in case where the voltage of the power supply line reaches a predetermined voltage.

A power supply device supplying power to a device via a power line is provided, where the power supply device includes a first voltage generation unit configured to generate and supply a first direct voltage to the power line, a second voltage generation unit configured to generate and supply a second direct voltage lower than the first direct voltage to the power line, a measurement unit configured to measure a voltage of the power line, a control unit configured to control supply of the first direct voltage with the first voltage generation unit after starting supply of the second direct voltage with the second voltage generation unit, and a determination unit configured to determine a state of the power supply device based on the measured voltage and a first threshold value after starting the supply of the second direct voltage.
摘要:
An optical imaging system for a copier comprising at least a pair of multilens plates made from the same mold to have matched surface configurations. One of the pair of multilens plates is arranged to be rotated from the position of the other multilens plate through 180 degrees about an axis parallel to the longitudinal direction of the other multilens plate. A reflecting surface is positioned parallel to the axis of rotation for deflecting the optical path between the pair of multilens plates once or an odd number of times whereby a clear image is provided despite imperfections from molding.

摘要:
A forming die for forming a vehicle seat foam cushion member integrally on its surface with a pile-type fastener adapted to be engageable with a mating pile-type fastener provided on the back surface of a top cover member associated with the seat. In the forming die, there is formed a recessed groove, in which resiliently and frictionally secured is a base plate with an engageable member fixed thereto. The engageable member is capable of removable engagement with the pile-type fastener which is to be integrally provided on the cushion member.
