Abstract: PURPOSE:To provide a method for measuring the propagation constant difference between TE and TM polarizations of an optical waveguide by utilizing a scattered light heterodyne detecting method. CONSTITUTION:The light from a light source 1 is divided ink two, one light is emitted to an optional position on the side surface of an optical waveguide S to be measured, and connected to the waveguide area to form propagated lights of two orthogonal polarization modes of TE, TM, and the other light is guided as the same two modes of TE, TM from the incident end of the optical waveguide S, the respective modes are combined together, and the two modes emitted from the emitting end of the optical waveguide are separated by a polarized beam splitter 15. The frequency of one light is further shifted by a phase modulator 8 prior to the combination, and the detection signals of the two separated modes are added or subtracted to determine the period to the optical coupling position on the side surface of the optical waveguide S, thereby, the propagation constant difference between TE and TM modes is measured.

Title: Image matching device
Inventor: MIWA MICHIO
IPC: G06T3/00
Filed: 1987-09-25
Abstract: PURPOSE:To reduce the calculation volume to a required minimum by evaluating features of an image and operating picture elements stored in first and second image storage means in accordance with evaluation results. CONSTITUTION:An address generator 51 sends address information having a width stored in an evaluation result storage means 5 in vertical and horizontal positions with the position stored in an image position storage means 54 as the center, to image storage means 2 and 3. Picture element information in positions corresponding to this address information is successively sent to an exclusive OR device 55. The device 55 operates exclusive OR and sends it to an adder 53. The adder 53 calculates the total sum of picture element information. When the calculation of the total sum of exclusive OR in a dotted-line frame with one picture element, whose position is stored in the means 54, of the image in the image storage means 2 as the center is terminated, it is sent to an evaluating means 52. The dotted-line frame is moved vertically and horizontally to operate the total sum of exclusive OR in the same manner, and it is sent to the means 52. When the total sum for the position stored in the means 54 at present out of these total sums is smallest, the means 52 defines this position as the matching position between images stored in means 2 and 3.

IPC: G03B27/62
Filed: 1986-10-13
Abstract: PURPOSE:To display additional information inexpensively with a simple structure, by illuminating an additional information pattern with a lamp and forming the latent image of the additional information on a photosensitive body. CONSTITUTION:An additional information pattern 16 contains a transparent film fitted to the opening of a housing 15 and desired additional information, such as date, etc., written on the transparent film with opaque ink. The flash lamp 17 in the housing 15 is provided at the inner side of the additional information pattern 16 viewed from a photosensitive body 1 side. When the flash lamp 17 emits light, the optical image of the additional information written in the pattern 16 is projected to the front end section of the electrostatic latent image of the photosensitive body 1 and an electrostatic latent image corresponding to the additional information is formed at the front end section. When developing, transferring, and fixing works are performed on the latent image similarly to the electrostatic latent image corresponding to the picture of an original, the additional information is displayed at the front end section of the copied picture of transfer paper. Therefore, the additional information is inexpensively displayed with a simple structure.

Title: Catch basin
Inventor: KANEKO YOSHIO
IPC: E02D29/14
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To provide sufficient strength arrangeable on a road, and to effectively gather rainwater by arranging a water permeable hole in a central part of an outer cover, and arranging a downward inclining water introducing part toward the water permeable hole on a surface of the outer cover. SOLUTION: In an outer cover 4, a water permeable hole 41 is arranged in a central part, and a downward inclining groove 42 (a water introducing part) is arranged toward the water permeable hole 41. Catchment ribs 43, 44 are arranged on an under surface of the outer cover 4 by surrounding the water permeable hole 41. The water introducing part of the outer cover is formed as the groove 42 inclining toward the water permeable hole, and since an outer cover surface is almost flattened, even if a catch basin is arranged on a road, walking is not hindered. Thus, rainwater flowing in the outer cover 4 at raifall time efficiently flows to the water permeable hole 41 along an inclination of the groove 42 on a surface of the outer cover 4.  Since the catchment ribs 43, 44 are arranged on the reverse of the outer cover 4, rainwater passing through the water permeable hole 41 flows down just below by these catchment ribs 43, 44 to prevent scattering to a periphery.

Filed: 1995-08-16
Abstract: PURPOSE: To remarkably reinforce protein agglutination by using a surfactant polyoxyethyleneglycol nonylphenylether together with a protein precipitating agent. CONSTITUTION: A polyoxyethyleneglycol nonylphenylether such as surfactant Tritone N-101 or Emulgen 911 represented by the formula has an effect for preventing protein aggregations by a precipitating agent from being further bonded together to form a large precipitation, and holding the aggregations of the same proper size. It never prevent the protein agglutination by the precipitating agent. It itself has no agglutinating effect with the precipitating agent, and is a surfactant having an extremely high reinforcing effect. In this case, a sample to be intended is suitably a sample containing protein which is fractionated by column chromatography. As a protein coagulation reagent, for example, sulfosalicylic acid is given.
