Title: Track expansion device for magnetic levitated ground transportation system
Inventor: SUZUKI YOSHINARI
IPC: E01B25/30
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a track expansion device for a magnetic levitated ground transportation system capable of keeping intervals of the track rail joints short even if the interval between the girders greatly change by the girders expanding or contracting. SOLUTION: A track rail of 10 m is used. A connecting means 6 of the joint of girders 2, 3 within ±20 mm regulates the detached distance and the approached distance to 20±20 mm. A sleeper 5 of the joint of girders 2, 3 within ±20 m is supported by a sliding means 11 in a movable manner in the longitudinal direction. Even if a great change takes place in the joint of girders 2, 3, such change is dispersed to respective joints of a track rail 4 within the joint of ±20 m. Thus joint intervals of the track rail 4 can be kept short.

Title: Joining of ceramic to metal
Inventor: MINAMI NOBUYUKI
IPC: C04B37/02
Filed: 1992-09-18
Abstract: PURPOSE:To achieve sufficient bonding strength and air-tightness by soldering a metallic flange to an end of an alumina ceramic pipe with an active metal solder. CONSTITUTION:An iron-nickel alloy having a thermal expansion coefficient close to that of alumina ceramic (e.g. covar and 42 alloy) is used as the material for metallic flange. The width of the bonding face is 0.5-0.7 times the width of the end of the ceramics. The outer circumference of the flange is folded at an angle of 15-60 deg. relative to the end face at a position separated from the outer circumference of the ceramic pipe by a distance of >=0.2 times the thickness of the pipe. The inner circumference of the flange is folded at a position separated from the inner circumference of the ceramic pipe by a distance of >=0.1 times the thickness of the pipe at a curvature corresponding to 1-3 times the thickness of the flange and the flange is soldered to the pipe with an active metal solder. The soldered product has a strength and a gas-tightness to enable the use as the exterior case of a vacuum switch for power transmission and distribution.

Title: Thermal head
Inventor: KAMIMOTO KOJI
IPC: B41J2/335
Filed: 1989-10-20
Abstract: PURPOSE:To improve development of a color which is not of high quality in the first dot and subdue development of colors in the (n+1)th dots to a maximum possible extent by shifting the position where a thermal element is formed on a thermal head from the apex of a glazed layer which heaves up like a crest in the printing direction. CONSTITUTION:A thermal element 4 is formed at a position which is offset from the apex of a glazed layer 2 heaving up like a crest in the printing direction. Given the thicker part of the glazed layer than an ordinary head as A, the part of the same thickness as the ordinary head as B and the thinner part as C, the effect of heat accumulation and insulation is significant in the part A, and contrarily the heat release action is significant in the part C. Consequently, heat is accumulated in the glaze well before a voltage is applied to cause the n-th dot to develop a color. The time spent for the part A to reach a position where the (n+1)th dot is influenced in their color development is longer than those for the parts B, C. A considerable amount of heat is released during this travel time, so that the (n+1)th dot is hardly influenced in their color development. As a result, it is possible to maintain the high clarity of the first dot while subduing development of a color in the following dot immediately after printing.
