Title: Louver damper
Inventor: FUKUCHI TAKESHI
IPC: F23L13/00
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a louver damper in which vibration of damper blade and possibility of resonance are suppressed. SOLUTION: Protrusions 20a-20d are provided irregularly at least one of the front edge part or the rear edge part of a damper blade 30. Since the flow characteristics of fluid around the damper blade 30 become irregular in the span direction, flow around one damper blade 30 and thereby the fluid force being applied thereto can be prevented from tuning in the span direction. Furthermore, entire damper blades 30 constituting a louver damper can be prevented from resonating by arranging the protrusions 20a-20d at different positions from damper blade 30 to damper blade 30. The protrusions 20a-20d may be replaced by cuts. Furthermore, the protrusions 20a-20d or the cuts may be provided at any one of the front edge part or the rear edge part of a damper blade 30 and they may be arranged in combination.

As a result, controller of low computation capacity can be used in a component mounting device of this design, and consequently the mounting device can be lessened in cost. As components pass over the different parts of the mirror 19 respectively, contaminants are prevented from attaching to the mirror 19 or the mirror is protected against contamination, and in result the mounting device can be enhanced in image recognition reliability.
