摘要： PURPOSE:To prevent fluctuation of branched fluid flow rate in a piping system in which a header has branch pipes provided with fluid outlets at least in three directions, by providing a swirlling flow inducing device on at least a side of the branch pipes or the vicinity. CONSTITUTION:In a piping system in which a cross branch pipe 5 connected to a header 4 has connection of horizontal branch pipes 6, 6 and a vertical riser pipe 8, the longitudinal section cofiguration of a reducer 11 connected right above the cross branch pipe 5 is manufactured to have a steep slanting surface on a side and a vertical surface on the opposite side in the same manner as the inner surface of the branch pipe 5. By this configuration, the outlet center point C1 and the inlet center point C2 are made eccentric and the eccentric reducer 11 comes to have a function of swirlling flow inducing device. Thus, on the vicinity of the cross branch pipe 5 a stable counterclockwise swirlling flow is produced and smooth branching of the flow to the horizontal branch pipe 6, 6 is made possible.

摘要： PURPOSE:To make no cavity to be generated in adhesive for fixation of a heat pipe and to enhance strength when a long hole is to be provided in a rotating shaft of an electric rotary machine to insert a heat pipe thereinto to be fixed by a method wherein an air vent hole is provided at the end part on the blockade side of the long hole. CONSTITUTION:When the long hole 13 is to be provided inside of the rotating shaft 1 to insert the heat pipe 7 thereinto to be fixed, the air vent hole 15 to be interconnected with the outside part of the rotating shaft 1 is provided at the end part on the blockade side of the long hole 13. Accordingly when the adhesive 14 is to be poured into the gap between the heat pipe 7 and the long hole 13, because air can be discharged completely, no cavity is generated, and the enhancement of strength of joint and the reduction of thermal contact resistance can be attained.

摘要： PURPOSE: To improve the maintenance ability, the replacing workability, and the degree of freedom for insertion of an image pickup device, by providing a taking- out part, where an pickup signal is taken out froum an image pickup tube, in the front structure of a yoke assembly.
CONSTITUTION: A black mask 14 with a semiconductor aperture is fixed in a front shield 13 of a yoke assembly, and a recess groove 14a is formed in a part, which faces to a lead pin 3, in the back of the mask 14, and a metallic piece 15 for taking out a signal which has one end brought into contact with the face at the tip of the lead pin 3 by elastic force is arranged in this recess groove 14a, and the other end of the metallic piece 15 is screwed and fixed to the back of the mask 14 together with an FET substrate 16, which is attachable to the mask 14, by a screw 17. The tip of a signal lead wire 4 connected to an FET connector 6 is screwd to the other end of the metallic piece 15 also and is connected electrically, and the pickup signal outputted to the lead pin 3 on a light incident face 1a is transmitted to the FET connector 6 through the metallic piece 15 and the signal lead wire 14.

摘要： PURPOSE:To make it possible to extract only an image pickup tube easily by use of an image pickup tube extracting jig made of a frictional member that is equipped to a socket being fitted in the image picture tube and hermetically fixed to the image pickup tube by being pushed by a clamp screw. CONSTITUTION:The clamp nut screwed around screw part 2a of coil assembly 2 is detached by turning. With clamp screw 11 loosened, the screw is inserted into image pickup tube 1 and socket 10 is screwed into coil assembly 2. Next, clamp screw 11 is screwed into socket 10. Consequently, frictional member 12 deforms elastically and is hermetically fixed to image pickup tube 1. In this state, turning socket 10 so that the screw will be loosened from coil assembly 2 extracts image pickup tube 1 from coil assembly 2 together with this jig since image pickup tube 1 is sufficiently clamped by frictional member 12.
