Title: Device for recovering carrier
Inventor: YOSHIZUKA TAKESHI
IPC: G03G21/10
Filed: 1985-04-24
Abstract: PURPOSE:To prevent the surface of a photosensitive drum from being flawed by accumulated carriers by automatically recovering the carriers removed from the surface of the photosensitive drum to a pan. CONSTITUTION:The title device is provided with the photosensitive drum 1, a rotating roller 8, a magnet rod 9, the pan 10, a connection part 12, etc. When the roller 8 is rotated in the arrow B direction, the magnet rod 9 is moved upward along the surface of the drum 1. The carrier adhering to the surface of the drum 1 is attracted to the periphery of the roller 8 by magnetic attracting force applied when the magnet rod 9 is opposed to the drum 1, and then carried upward together with the magnet rod 9. When the roller 8 is rotated moreover and a vertical groove 11a storing the magnet rod 9 is located on the upper position, the magnet rod 9 is dropped from the vertical groove 11a by its rate weight and moved to the other vertical groove 11b through the connection part 12. Consequently, the carrier on the roller 8 is released from the magnetic attracting force of othe magnet rod 9 and dropped on the surface of the pan 10 in accordance with the rotation of the roller 8. Thus, the carrier can be recovered automatically and effectively with the simple constitution.

Title: Method for measuring thickness of water pipe wall
Inventor: MIYAZAKI TAKAYUKI
IPC: G01B17/02
Filed: 1988-04-12
Abstract: PURPOSE:To measure the thickness of the wall of a water pipe with high accuracy, by filling the water pipe with water and directing an ultrasonic wave into the water pipe from the outer surface thereof. CONSTITUTION:A water pipe 1 is filled with water 3 and an ultrasonic probe 4 is put on the outer surface 2b of the water pipe 1 outside a furnace at a proper position. Then, an ultrasonic wave is directed into the part 2a to be measured of the water pipe 1 from the ultrasonic probe 4 provided on the outer surface 2b of the water pie 1 outside the furnace on the opposite side thereof. Whereupon, since the water 3 filling the inside of the water pipe 1 transmits the ultrasonic wave as a medium, the ultrasonic wave propagates from the outer surface 2b of the water pipe 1 to the part 2a to be measured through the water 3. By analyzing the reflected waves S1, S2, S3 from the part 2a to be measured, the thickness of the water pipe wall can be measured.

Title: Measurement of astigmation
Inventor: SUEDA TETSUO
IPC: G01M11/02
Filed: 1982-05-25
Abstract: PURPOSE:To measure astigmation at a high accuracy by arranging a light source on an image surface of a lens to be measured to observe the condition of beam forming an image of the light source expansively projected from the optical system of inverted projection. CONSTITUTION:A lens 12 to be measured coincides with a light source 11 in the position of imge formation, namely, the position of the image surface. A Hartmann plate 13 has a pin hole array on one section of the pupil containing the optical axis. Light emitted from the light source 11 is projected invertedly with the lens 12 being inspected to make a parallel light flux and forms a beam corresponding to an incident pupil of the lens 12 with the Hartmann plate 13. The beam enters a photosensitive surface 15 being focused with a collimator lens 14. On assumption that the astigmation of the lens 14 is highly satisfactory, when the lens 12 to be measured has no astigmation and the Hartmann plate 13 has openings arranged at an equal space, the pattern of beam recorded on the photosensitive surface 15 becomes equal in the space. When the lens 12 being inspected has any astigmation, it does not. The deviation between spaces being equal and not corresponds to horizontal astigmation of the lens 12 being inspected.

Abstract: PURPOSE:To provide a high-performance composite separator of high accuracy at low cost by fitting a conductive oxide plate in a grooved portion having a flat bottom passing from one end surface to the opposite end surface of the air-electrode side portion of a heat resistant metallic main body portion. CONSTITUTION:A separator 1 is a combination of a heat resistant metallic main body portion 1A and a conductive oxide plate 1B, with plural lines of gas circulating channels and projections formed on the bottom surface of the main body portion 1A to make contact with the fuel electrode surface of a cell. A grooved portion 1d consisting of a flat surface passing from on end surface 1g to the opposite end surface 1g is formed in the center of the top surface of the main body portion 1A other than both end portions 1d, and the plate 1B is fitted into the grooved portion 1e. Since the grooved portion 1e is not a recess, it is cut by a shaping machine and has its surface finish polished by a polishing machine. Similarly, the bottom surface of the plate 1B is ground and polished. Therefore, the manufacturing process is simple and the contact resistance of the fuel cell is decreased by the close contact between both sides. Also, plural lines of air circulating channels 5c and projections 5b are formed on the top surface of the plate 1B to make contact with the air electrode of the cell.

Abstract: PURPOSE:To prevent the destruction of the storage contents of a memory part and at the same time to check a battery by connecting a battery terminal of a battery circuit to a connecting part via an impedance converting circuit. CONSTITUTION:The node of a diode 3c is connected to a battery voltage detecting terminal of a connecting part 1 which detects the terminal voltage of a battery 3a of a battery circuit 3 via an impedance converting circuit 6.

Thus the storage contents of a memory part 2 are never destroyed and kept. As a result, the terminal voltage of the battery 3a is detected via the part 1 while the memory back-up reliability is secured. Then the battery 3a can be checked.
