Title: Optical device
Inventor: KONNO YOSHIHIRO
IPC: G02B6/28
Filed: 1991-05-31
Abstract: PURPOSE:To enable an optical device to act as a polarization nondependent isolator by arranging an optical isolator between two birefringent crystalline plates, and arranging polarization preserving fibers between these mutual plates so as to control polarization planes. CONSTITUTION:Forward directional light to be propagated from a Faraday rotor F1 to F2 is divided into normal light and abnormal light by means of a birefringent crystalline plate P1. Furthermore, in order that the light beam polarization planes become parallel with each other on the light outgoing sides of polarization preserving fibers PPF11 and PPF12, the PPF11 is twisted/fixed in the clockwise direction by 45 deg. as well as the PPF12 is twisted/fixed in the counterclockwise direction by 45 deg. with the light beam propagation axis as its center so as not to be restored to the original state. Next, polarization of light outgoing from a polarization rotating isolator 1 adjusted in the maximum wave transmittable direction is rotated by 45 deg., and is connected to the PPF21 and 22. Here, either one of them is twisted until the polarization direction is put under a 90 deg. rotated condition on the incident/outgoing edges, and is fixed so as no to be restored to the original state. Further, the lights are propagated to P2 as the mutually/perpendicularly crossing separated normal light and abnormal light, and in the case of taking into F2, the lights are brought together, and can be connected to the F2 from F1 regardless of the polarization.

Title: Manufacture of microcapsule
Inventor: ISOBE YASUSHI
IPC: B01J13/18
Filed: 1987-06-24
Abstract: PURPOSE:To form a wall membrane having improved heat resistance, water resisting property, and oil resistance, with smaller exposed portion, by mixing aqueous medium in which a small quantity of a specific urea-formalin resin is made to coexist with hydrophobic fine powders so as to produce microcapsule. CONSTITUTION:Microcapsule having membrane material thereof composed of urea-formaldehyde resin and core material thereof composed of hydrophobic fine powders is produced by mixing aqueous medium in which a small quantity of urea-formalin containing methylene bond is made to coexist with prepolymer obtained by methylol formation of urea-formaldehyde with hydrophobic fine powders. If a small quantity of methylene resin is present when the hydrophobic fine powders are thrown in, the methylene resin will attach preferentially to the hydrophobic fine powders to effect surface activity, with the result that dispersibility of fine powder is improved, so that uniform wall membrane is formed around the fine powders, thereby preventing scales from attaching to reactor surfaces.

Filed: 1984-07-27
Abstract: PURPOSE:To obtain an inexpensive system by utilizing the degree of freedom of the manipulator and obtaining information on an object by use of only a single ultrasonic sensor as a short-range sensor, and reproducing the object shape from the information and information of the sensor. CONSTITUTION:The ultrasonic sensor 2 which recognizes the shape of the object 3 is fitted to the arm of MP1. The surface image of the object 3 is only reproduced for its shape and position vector inversion S from the MP1 is only calculated as to each point constituting the surface of the object 3. Further, the direction and distance between the sensor 2 and object 3 need to be calculated and the sensor 2 as a non-contacting distance sensor having large directivity is used for the purpose to measure the distance. Further, the position vector at a point on the surface of the object 3 is calculated from the distance information and the attitude angle (position information) of the sensor 2. The calculation of the position information and the reproduction of the image are performed by a CPU. The CPU uses the MP1 so as to obtain the maximum output of a received wave, and controls the direction of the sensor 2. Consequently, the inexpensive MP system is realized.
