Optical coherence tomographic device

An optical coherence tomographic device of polarization-sensitive type may include: an image capturing unit configured to capture a tomographic image of a subject eye, and a display unit configured to display the tomographic image captured by the image capturing unit. The tomographic image may include at least two images selected from a group consisting of: an image showing a tissue in the subject eye by scattering intensity, an image showing a melanin distribution in the subject eye, an image showing a fiber density in the subject eye, an image showing a fiber direction in the subject eye, and an image showing a blood flow in the subject eye. The display unit may be configured to display the at least two images at a same position and on a same cross section such that the at least two images are superimposed on each other.

An apparatus for cutting green ceramic bodies, includes a traveling path for green ceramic bodies, beds for supporting green ceramic bodies at constant intervals in series along the traveling path, an arm on each side of the traveling path, two drive portions for moving respective arms perpendicularly relative to the traveling path, a drive portion for moving both arms in the same direction as the traveling path, a wire for cutting green ceramic bodies, extending between the arms, and wire supporting portions, on respective arms. Each wire supporting portion includes a servo motor with an axis of rotation, a magnet member around the axis of rotation, a bobbin having a conical surface around which wire is wound, and magnetically coupled to the axis of rotation by the magnet member, and a traversing mechanism for varying the position where the wire is wound around the length of the conical surface.

Cutting apparatus for ceramic green bodies

The present invention provides a cutting method of a ceramic honeycomb formed body for cutting the ceramic honeycomb formed body with a fine line stretched at an appropriate tension substantially at right angles to the direction of throughholes thereof. The method comprises the steps of providing a cutting guide groove running through the outer periphery of the ceramic honeycomb formed body substantially at right angles to the direction of throughholes , and putting a fine line to the cutting guide groove , to cut the ceramic honeycomb formed body only by pressing the fine line against the ceramic honeycomb formed body . By using this cutting method, it is possible to cut a ceramic honeycomb formed body having thin partition walls of under 125 &mgr;m without causing a distortion. The possibility to reduce the cutting frequency of the fine line leads to possibility to improve the cutting efficiency.

Cutting method of ceramic honeycomb formed body

In order to prevent deformations, cracks and breakages of thin-walled ceramic honeycomb shaped bodies upon conveying them, a system for conveying such ceramic shaped bodies and cradles used for the system are provided. Since, in the first aspect of the present invention, the cradle is lifted up from the first conveyor path - , transferred to the next conveyor path - having a different conveying direction from that of the first one while keeping the ceramic shaped bodies lifted, and then put down on the next conveyor path - when the conveying direction of the cradles on which the ceramic shaped bodies are placed is changed on the way of the conveyor , and since, in the second aspect of the present invention, the conveying speed of the cradles on the conveyor is gradually reducing to stop the cradle on the way of the conveyor , when the cradles on which the ceramic shaped bodies are placed are stopped on the way of the conveyor , the impact on the ceramic shaped bodies can be absorbed in each cases. The cradle consists of an aluminum base , a support portion provided on the base and having a receiving portion formed on a side opposed to the side contacting the base in a shape corresponding to the ceramic shaped body , and a cushioning material provided to cover the supporting member and the receiving portion of the supporting member
