Title: Combustion device
Inventor: KONDO MASAMITSU
IPC: F23N5/16
Filed: 1993-05-24
Abstract: PURPOSE:To realize a combustion device producing a low noise which muffles combustion sound of the combustion device under an adaptive active control and at the same time restricts occurrence of vibratory combustion. CONSTITUTION:A pressure variation of combustion sound is sensed as a sound pressure by a first pressure sensor 16 arranged at a burner 12. An inverse phase signal of the combustion sound is calculated by an operation device 18 in response to this signal. Pressure variation in inverse phase is produced from a sound wave generating means 19 provide at an outer part of a discharging port 14 is generated and the combustion sound outputted from the discharging port 14 is muffled by a phase interference. The varying combustion sound is always kept minimum under an adaptation control for performing an evaluation of an amount of sound muffling in response to a signal got from a second pressure sensor 17 arranged outside the discharging port 14. Occurrence of the vibratory combustion is also compared by a comparing means and a memory device and then fuel and an amount of air are controlled under an instruction got from a main body control device 11.

Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain a low-priced strong optical resonator made small in size and light in weight by providing a cantilever which has a reflection surface and whose one end is attached to a base plate and further attaching a bimorph actuator responding to electric excitation to the cantilever. SOLUTION: The cantilever 10 is attached to the base plate 14 through its one end 12 and its 2nd end 16 is freely extended on the base plate. The bimorph actuator 18 exists on an insulating layer 17 at the fixed end 12 of the cantilever 10. The temperature of the actuator 18 rises and falls by applying a current to the layer 17. When the current is increased, the actuator 18 is heated and the cantilever 10 is curved downward and goes away from its stop position, and when the current is decreased, the actuator 18 is cooled and restored to its stop position. A part of the reflection surface 25 is covered with the free end 16 of the cantilever 10. The optical resonator is brought by moving the surface 25 in accordance with the excitation of the actuator 18.
