摘要： A heat transfer body 3 is prepared. The heat transfer body 3 forms an inner space 7 for existence of one of a higher-temperature fluid or a lower-temperature fluid. The heat transfer body 3 constitutes a heat exchanger, and is formed of a copper material as a wall surrounding the inner space 7. In the wall, a flow path through which the other of the higher-temperature fluid and the lower-temperature fluid flows is formed. By LMD treatment, an LMD layer is formed directly on an outer circumferential surface 3a of the heat transfer body 3. In the LMD treatment, a metal material is supplied to a supply position on the outer circumferential surface 3a, and the supply position is irradiated with laser light to form an LMD layer 5. An energy density of the laser light is set to melt both the metal material and the outer circumferential surface 3a.

摘要： A docking device including: a base ring 2 disposed in a first space vehicle A; a first-side capturing ring 3 for coming into contact with the second space vehicle B; six links 4 that constitute a parallel link mechanism 5 for coupling the base ring 2 to the first-side capturing ring 3; and linear actuators 10, each of which extends and contracts the link 4 by using a motor 13 as a driving source, wherein resistance generation mechanisms, each of which generates a regenerative current in the motor 13 of the linear actuator 10 to produce resistance force when the second space vehicle B comes into contact with the first-side capturing ring 3 and the link 4 receives a compressive load, are provided. Correction of misalignment with the second space vehicle, and attenuation of inertia force that the second space vehicle has can be performed without requiring complicated electrical control, and simplification and cost reduction of an electrical system can be implemented.

摘要： An obj ect of the present invention is to provide a stitched carbon fiber base material which exhibits excellent form stability and shapability, ensures excellent handleability in processing a wet prepreg in CFRP manufacturing steps, and facilitates production of a three-dimensional shape, and to provide a wet prepreg using the same. Each sheet material (1) is formed by arraying carbon fiber lines (11, 11, ...), each having a predetermined width, in parallel with one another. Meanwhile, an array direction of the carbon fiber lines (11) of each sheet material (1) is set to form an angle in a range from ±30° to ±60° to a weaving advancing direction of a stitching yarn (2) . Moreover, a stretch ratio of the stitched base material in its lengthwise direction in a case where a load per inch width of the stitched base material is applied in the weaving advancing direction of the stitching yarn (2) is equal to or below 4% when the load is 5 N, and is equal to or above 10% when the load is 25 N.

摘要： Multipliers 21a and 21b output values, which are obtained by multiplying a total drive command value E s by first and second gains G 1 and G 2 , respectively, as first and second drive command values E 1 and E 2 . Controllers 23a and 23b control first and second actuators (motors) 5 and 7, respectively, on the basis of the first and second drive command values. The detection values of the drive amounts of the actuators are denoted by E f1 and E f2 , respectively, and the detection value of the drive amount of a driven body is denoted by E f . A gain calculator 27 calculates the gains G 1 and G 2 on the basis of E f1 , E f and E f2 . An upper limit value of E f , which denotes the drive amount of the driven body, is denoted by L max . When E f1 , E f2 or E f approaches zero, the first gain G 1 is brought close to (E f1 - L max /2)/(E f - L max ).
