摘要： PURPOSE: To lengthen a heat transfer passage, to suppress the radiation of heat from a honeycomb body and to reduce the quantity of heat radiated by fixing the upper stream side of a protective tube on the upper stream side or downstream side of an exhaust passage and joining the downstream side of the honeycomb body to the inner wall of the downstream side of the protective tube. CONSTITUTION: A flat sheet 113 is superposed on a corrugated sheet 112 and they are spirally wound to form the honeycomb carrier 11 of a catalytic converter 10. At this time, slits 111 are formed in the sheets 113, 112 from the central part of the carrier 11 in the longitudinal direction toward the end on the upper stream side of exhaust gas. The inside diameter of a protective tube 12 covering the periphery of the carrier 11 on the upper stream side of exhaust gas is made larger than that on the downstream side and a gap 100 is ensured around the slits 111. The positional relation between the honeycomb carrier 11 and the protective tube 12 is decided so that the tube 12 protrudes from the end 11a of the carrier 11 on the upper stream side in the axial direction. The tube 12 is then irradiated with laser beams from the outside of the tube 12 except the notches 121 to fix the corrugated sheet 112 and the tube 12 by welding.

摘要： PURPOSE: To provide an inexpensive metallic catalyst carrier capable of heating a catalyst to the activation temp. of a catalyst in a short time only with the heat of a waste gas and having a sufficient strength. CONSTITUTION: A catalyst is deposited on a honeycomb body formed by alternately winding a flat sheet 2 and a corrugated sheet 3 to constitute a metallic catalyst carrier 10. In a catalytic converter 1 consisting of the carrier 10, plural slit arrays 4 extending in the direction orthogonal to a waste gas direction are arranged at leat a part on the upstream side of an exhaust line, and a low-heat-capacity and high-heat-transfer region is formed on the downstream side of the exhaust line. Further, the upstream part of the converter 1 is covered with an outer cylinder having an air insulating layer, and the upstream side of the outer cylinder 8 is firmly held to the exhaust line.

摘要： PURPOSE:To evade photographing a supporting tool for supporting an object by making the surface of the supporting tool smooth and setting it so that a reflected light beam which is reflected at a fixed reflection angle from the smooth surface except the edge of the supporting tool may not be made incident on a hologram dry plate. CONSTITUTION:The shape is decided so that the edge 23 of a glass substrate 2 may be out of an optical path of the irradiating light beam 5. Therefore, an irradiating light beam 5 is not irregularly reflected by the edge 23 of the substrate 2. Then, the angles of the substrate 2 and the irradiating light beam 5 are set so that the hologram dry plate 3 may not be arranged in the optical paths of the irradiating light beam 5, the surface reflected light beam 6 and the back surface reflected light beam 11. Therefore, the reflected light beams 6 and 11 reflected by the glass substrate 2 are not made incident on the object 1, so that only the object 1 is photographed on the hologram dry plate 3. Thus, the supporting member is prevented from being photographed.

摘要： PURPOSE:To obtain a vehicle mounted hologram meter which can avoid driver's dazzlement due to ghost images by providing a Lippmann hologram, a regenerated light source and a smoke light source, and arranging these parts at the specified positional relationship. CONSTITUTION:The numerical scale of each meter is recorded in a Lippmann hologram 33. A regenerated image 39 of said scale is displayed on the rear regenerating plane with the regenerated light. The hologram is attached to a position in front of the dial of a conventional meter. A regenerating light source 34 emits light from the lower side of a specified attaching angle to the upward direction with respect to the normal line H of the hologram 33 and from the front side of the hologram 33. A smoke plate 37 has a transmittance which reduces external light inputted on the surface of the hologram 33. The smoke plate 37 is provided in front of the light source 34. Reflection of driver's face and the like is prevented. In this arrangement, the regular regenerated image of the hologram 33 can be observed through the regular image of a master hologram when the light from the light source 34 is projected from the lower side with respect to the normal line H. Said regenerated image is observed through the smoke plate 37.

摘要： PURPOSE:To improve the sealability of the fluid while the increase of the power loss and the abrasion by the friction between scroll members is suppressed. CONSTITUTION:A groove 7e is provided in the center side tip of at least either of spiral blades 7a (the illustrated reference symbol is for a movable scroll member 7) of a fixed scroll member 3 and the movable scroll member 7 in a scroll type fluid machine such as a scroll compressor, and a vane 22 is inserted, and the energizing is made to the left as shown in the figure by a coil spring 18. The vane 22 of the illustrated example is engaged with the spring 18 through a second vane 23 having a tapered surface not shown in the figure. The tip 22a of the vane 22 is pressed against the surface of the opposite spiral blade not shown in the figure, and the second vane 23 is pressed against the side plate not shown in the figure to achieve the sealing. The sealability of the working space in the vicinity of the center part where the pressure of the fluid becomes high is chiefly improved, and the leakage of the fluid is reduced on the whole.

摘要： PURPOSE:To restrict the increase of power loss and abrasion due to the friction between scroll members, and while to improve the liquid sealing property. CONSTITUTION:A part of a spiral vane 7a, which is arranged close 'to the center, of any one of a fixed scroll member and a movable scroll member of a scroll type fluid machinery such as a scroll compressor is formed with a separate inner peripheral vane 22 so as to be displaced separately from a part arranged close to the outer peripheral part. Tubular elastic bodies are fitted out of pins 20 planted in an end plate 7b, and these pins 20 are inserted to holes 22a of the inner peripheral vane 22. Shape of the inner peripheral vane 22 is formed a little larger. Since the inner peripheral vane 22 is energized by the elastic bodies and pushed to an objective spiral vane, sealing property of a contact part near the center, in which pressure of the fluid inside of a crescent-shaped operation space is raised, is mainly improved, and as the whole, effective seal is obtained. As an energizing means for energizing the inner peripheral vane 22, material except for elastic body can be used.

摘要： PURPOSE:To prevent the occurrence of biased abrasion on vanes and reduce power loss by keeping the sealing force in the radial direction between the spiral vanes of a scroll member nearly constant. CONSTITUTION:A ring 12 smaller in diameter than the circular eccentric inner periphery 10b of an eccentric ring 10 integral with a drive shaft 5 and rotatable against a driven shaft 7C integral with a moving scroll member 7 is inscribed and friction-coupled with the inner periphery 10b. A balance weight 13 is fitted to part of the outer periphery of the ring 12. When the moving scroll member 7 is rotated together with the drive shaft 5 by a pin 11, part of the centrifugal force by the revolution of the moving scroll member 7 is offset, and the remaining centrifugal force is utilized as the sealing force in the radial direction between vanes. Even when the profile of the vanes of a scroll member has an error and the drive shaft 5 does not coincide with the axis of a fixed scroll member 3, the remaining centrifugal force is increased or decreased by the component force of the driving force applied to the contact between the eccentric ring 10 and the ring 12 to keep the sealing force constant.
