The external height (h) of the tube (1) is set to be not more than 2 mm, The internal height (h1) of each path (10, 11) is not more than 1.2 mm. The ratio of the width (w1) to the internal height (h1) is within the range of 1.8 to 6.0. A plurality of projections (12, 12a, 12b, 12c) continuously extending in the length direction are provided in each refrigerant path (10, 11). Grooves (13) adjacent the projections have smooth bottoms and the ratio of the height (h2) of the projections (12; 12a. 12b, 12c) to the internal height (h1) is within the range of 0.055 to 0.25. The pitch (p) of the projections preferably ranges from 0.25 to 0.6 mm. Various projection forms are disclosed.

Abstract:
A method for strengthening glass by implanting accelerated ions into a glass sample 8. The ions are implanted deeper than minute cracks present on the surface of the glass or to the depth of at least 5ƒÊm from the surface. Glass is transformed where the ions are implanted, so that the transformed region is formed deeper than the minute cracks or a position located at least 5ƒÊm deep from the surface. The progress of the cracks on the surface of the glass is suppressed by this transformed area, thus strengthening glass. According to the invention, no beam focusing optical system such as a laser beam device is necessary. Further, a large glass member can be strengthened in a short time because of a larger area into which ions can be implanted at a time. Further, the method is subjected to no restrains in thickness, surface shape or material of glass.
Abstract:
An ion implantation method and an ion implantation apparatus which can uniformly implant ions into a thick region of a sample are provided. The ions to be implanted into the sample are once accelerated so as to have substantially equal velocities, decelerated by being allowed to pass through a vibrating thin plate having an uneven thickness so as to be decelerated in accordance with the thicknesses of the portions of the thin plate which the ions pass through, and then implanted into the sample. Accordingly, into targeted portions of the sample where the ions are to be implanted, the ions having unequal velocities are implanted. The implantation depths of the ions vary depending on the velocities of the ions, whereby a thick implantation region can be obtained.
Abstract:
The present invention provides a safe, inexpensive, and high yield means of producing a hydrolyzable silicon-containing compound, e.g., an organooxysilane and the like. A compound (A) represented by the general formula R 1 -O-R 2 wherein R 1 represents a C 4-30, substituted or unsubstituted, tertiary alkyl group or aralkyl group and R 2 represents a C 1-30, substituted or unsubstituted, monovalent hydrocarbyl group or acyl group, is reacted in the presence of a Lewis acid catalyst with a halosilane (B) represented by the general formula R 3 m SiX 4-m wherein R 3 represents the hydrogen atom or a C 1-30 substituted or unsubstituted monovalent hydrocarbyl group, X is independently bromine or chlorine, and m represents an integer from 0 to 3.
Abstract:
In an optical device of the invention, ions are implanted into at least a portion of an optical waveguide core having a substantially square or rectangular cross-section, and the ion-implanted portion is formed so as to be asymmetrical with respect to each of the vertical and horizontal line passing through the center of the cross-section of the optical waveguide core. Preferably the ion-implanted portion includes a central portion of the square or rectangular cross-section of the optical waveguide core, and is formed along any one of two diagonals.
Abstract:
PROBLEM TO BE SOLVED: To provide a networking remote learning system and a learning method, and a managing server and a coordinator, and a program which can enhance the effect and the efficiency of learning. SOLUTION: The networking remote learning system 10 comprises the managing server 20, a terminal apparatus for a lecturer 40 and a terminal apparatus for a student 50 connected through a network. Conditions for the lecturer are previously stored in and registered with a storing means of the conditions for the lecturer 34 in the managing server 20. The conditions for the lecturer previously stored in and registered with the storing means 34 are automatically searched by a searching means of the conditions for the lecturer 22 based on conditions for the student requested by the student. The lecturer meeting the conditions can be automatically determined and a reservation for attending a lecture can be registered.
