Title: Production of ceramics-metal joined body
Inventor: KUBOTA YOSHIHIRO
IPC: B23K20/00
Filed: 1990-05-31
Abstract: PURPOSE:To reduce a material cost and to improve the strength of adhesion by interposing a metallic powder compsn. which forms eutectic at the temp. below the m. p. of a metal in place of active metallic foil between ceramics and the metal. CONSTITUTION:The metallic powder compsn. which forms the eutectic at the temp. below the m. p. of the metal used on the ceramic member is imposed on this member and a metallic member is imposed thereon. These materials are heat treated in an inert gaseous atmosphere in a vacuum. The metallic powder compsn. is expressed, in weight %, by Cu-Ti(28.0), Fe-Ti(32.0), Mo-Zr(69.0), etc. The eutectic temps. thereof are successively 880, 1085, 1520 deg.C and may, therefore, be selected according to conditions. These metallic powders are formed as the mixture and reaction is effected better as the grain sizes thereof are smaller. The waving and ruggedness on the surfaces of the ceramic member and the metallic member are thus easily followed up. The strength of adhesion is increased in this way. In addition, the metallic powder compsn. is more inexpensive than the active metallic foil.

IPC: B60R21/201
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To restrain the self-restoring force of an airbag and to inflate and deploy the airbag smoothly by binding both longitudinal ends of the airbag folded. SOLUTION: This device comprises a folded airbag 1, a protective patch 6 folded over and wrapping the airbag 1, and a narrow strip of wrapping 6f formed by cutting a portion of the protective patch 6 to bind both longitudinal ends of the airbag 1 via the protective patch 6.

Abstract: PURPOSE:To align Japanese rice cracker dough on a transfer conveyor by connecting an optional cavity of a rotary aligning device with a pressure reducing port so as to hold the dough in a suction nozzle and dropping the dough onto the preset position when the dough approaches right above the conveyor. CONSTITUTION:In a drum part 12, on which suction nozzles are projected, a high pressure blower is connected with a straight opening of an air distribution pipe 17 in the right end, and the inside of a cavity 13, which is rotated to the position of the straight opening, of the drum 12 is highly decompressed, so that a suction nozzle (a) in the corresponding position sucks Japanese rice cracker dough to its point end intensively. While the drum 12 rotates and the cavity 13 is situated in the area of a hook-shaped opening 22 of the air distribution pipe 17, through an air suction port 23 of the drum supporting shaft 16 and the dough is held on the point end of the nozzle (a) in the cavity 13 by another blower. In the suction nozzle (a) sucking and holding the dough, its holding force for the dough is weakened when its cavity 13' approaches a straight open port 21'' serving as an atmosphere releasing port according to the drum rotation. In this process, a positioning stopper 9 arranges a dropping position for the dough, so that lumps of the dough before and behind are prevented from lying one above the other on a wire net conveyor 6.

Abstract: PROBLEM TO BE SOLVED: To achieve a long life by mounting a sensor cip, which is formed in a bridging structure on a cavity wherein another temperature detecting part penetrates in the flowing direction of a fluid on a mounted substrate having a recessed flow path along the fluid flowing direction, in a face-down manner. SOLUTION: On a sensor substrate 24, a supporting part 26 in a bridging structure, whose longitudinal direction intersects the cavity 25 at a right angle, is formed on the cavity 25 formed in parallel with the fluid flowing direction. On the supporting part 26, a thin-film heater 27 is formed. Furthermore, temperature sensors 28 and 29 are formed so as to hold the heater. The thin film heater 27 forms a first temperature detecting part 30 together with the temperature sensor 28 and forms a second temperature detecting part 31 together with the temperature sensor 29 in the right-angle direction to the fluid flow in both cases. On the mounted substrate 23, a hole 36 larger than the cavity part 25 of the sensor chip 22 is formed in parallel with the fluid flow as a recessed flow path. On the mounted substrate 23, the sensor chip 22 is mounted in the phase-down pattern on the hole 36.  Thus, the temperature detecting parts 30 and 32 are exposed in the fluid, and the flow rate and the flow velocity can be detected.
