Title: Method for checking cut-off wavelength of optical fiber
Inventor: TATSUTA MITSUHIRO
IPC: G01M11/02
Filed: 1987-03-09
Abstract: PURPOSE:To rapidly detect an optical fiber cut-off wavelength, by investigating the magnitude relation between the light output change quantities after and before bending is imparted to an optical fiber, and a predetermined threshold value and judging the magnitude relation between the cut-off wavelength of the optical fiber and the wavelength of a light source. CONSTITUTION:At first, an optical switch 7 couples an optical cord 6A and an optical fiber 3 to be measured, and the light of a light source 5A having a wavelength lambda1 is incident to the fiber 3 in such a state that the fiber 3 is straight and the light output P1 thereof is measured by a light detector 4. Next, light output P2 is measured by the detector 4 in such a state 3A that the fiber 3 is bent by a bending imparting part 8. Next, the switch 7 is changed over to successively couple the fiber 3 with optical cords 6B, 6C. The light outputs P3-P6 are measured with respect to respective couplings in the straight and bent states of the fiber 3. From the light outputs P1-P6 thus calculated, the magnitude relation between the cut-off wavelength of the fiber 3 and the wavelengths lambda1, lambda2, lambda3 of the light source is judged. By this method, the cut-off wavelength of the optical fiber can be rapidly checked.

Title: Dry-type rice washing device of cereals
Inventor: KORESAWA YOSHIHIRO
IPC: B02B1/04
Filed: 1993-03-12
Abstract: PURPOSE:To obtain a dry-type rice washing device which produces high-quality unwashed rice by providing air jet orifices which blow up cereals to be supplied by air ejected upward obliquely from an air jet orifice side and direct the cereals to the air jet orifice side, at the bottom of a rice washing chamber. CONSTITUTION:If cereals are supplied to a rice washing chamber 1, bran sticking to the surface of each grain of the cereals is efficiently polished off by mutual contact between grains and contact between the grain and an air current, using the air current spewing upward obliquely from an air jet orifice 3 side on the other end of the rice washing chamber 1 through an air blowup orifice 4 arranged at the bottom. Bran separated from the cereals containing the polished-off bran, which is far lighter than the cereals, is carried away by an air current from an air exhaust orifice 6 at the top of the rice washing chamber 1, and is separated from the cereals discharged from the air jet orifice 3. Further, rice washing is achieved by air current without the help of mechanical power in the absence of water.

IPC: G01V3/08
Filed: 1993-03-12
Abstract: PURPOSE:To discriminate the position and the kind of the electric fused tube fitting of a tube made of synthetic resin embedded in underground without digging. CONSTITUTION:Electric power is supplied from a transmitter 50 into terminals 35, 36, 45 and 46 of the heating wires of tube-fitting main bodies 32 and 42 of an electric fused tube fitting 31, which is embedded in soil 30, through locating wires (position searching conductors) 51, 52, 53 and 54.

Title: Disk reproducing device
Inventor: KURUMADA MASAKAZU
IPC: G11B17/051
Filed: 1989-03-03
Abstract: PURPOSE:To surely place and fix a compact disk on a turn table by providing a centering mechanism equipped with a pair of centering cams which have a large diameter part and a small diameter part and a pair of central pins which are implanted in these cams and energized. CONSTITUTION:When a small diameter disk 106 is eccentrically inserted into a disk slot, it contacts on either of a pair of centering pins 19 and 20. When the disk 106 hits the pin 19, the centering cam 15 tries to turn clockwise against the energizing force of an extention spring 21, and the large diameter part 1a, instead of the small diameter part 15b which is in contact with a stopper arm 13, tries to get into contact with the disk 106. Consequently, the arm 13 tries to turn clockwise, around a supporting pin 17. Although, since the other edge of the arm 13 is still in contact with the large diameter part of a centering cam 16, the clockwise turning of the arm 13 is prevented with a large diameter part 16a, thus the disk 106 is stopped by the pin 19 and forced to the center of the disk slot 2.

Abstract: PROBLEM TO BE SOLVED: To provide a preventive fence which is generally laid out along a walkway slightly near a carriageway and laid out intersecting with the carriageway at right angles during earthquake or the like and capable of preventing the approaching of a car running on the carriageway. SOLUTION: A vehicle approaching preventive fence 1 is generally laid out along a walkway A on the side of a carriageway B of a road comprising the walkway A and the carriageway B holding a low offset area which sandwiches the walkway A.

In the case where there is no offset area, this construction makes it possible to eliminate the need for the adjustment and contrive to prevent the approaching of vehicles promptly and accurately.
