Title: Resonance detector
Inventor: HAYAKAWA YOSHIKAZU
IPC: F01N1/02
Filed: 1989-06-09
Abstract: PURPOSE:To securely and easily detect resonance generated in a duct as temperature variation by providing a temperature sensor which is disposed on a position where gas particles are in large motion through the resonance in the duct and a heating part or cooling part which is disposed close to the temperature sensor and relatively high or low in temperature to the temperature in the duct. CONSTITUTION:The temperature sensor 3 is disposed on the node of the resonance mode of an exhaust pipe 2 and a heater 4 is disposed close to the temperature detection point of the sensor 3. The heater 4 is held at temperature higher than the temperature of exhaust gas close to the sensor 3 and positioned on the downstream side of the sensor 3. When no resonance occurs, the detected temperature of the sensor 3 depends upon the exhaust gas temperature. Then when a resonance mode having its node close to the resonance detection sensor 1 at certain rotating frequency occurs, the behavior of exhaust gas particle becomes active to accelerate the heat exchanger between the sensor and heater 4 and the detected temperature rises temporarily. At the time of deceleration, the detected temperature rises temporarily in resonance similarly. The generation of resonance can be detected from this temperature variation.

Abstract: PURPOSE:To enable a positive ignition to be carried out without being influenced by an air flow within a combustion chamber by a method wherein an earth electrode arranged in spaced apart relation with a flame port of a burner plate and an electrical discharging electrode plate oppositely facing against the earth electrode are provided. CONSTITUTION:A plate-like burner 19 is composed of a burner plate 16 composed of ceramic material or the like and provided with several flame ports 15, a burner case 17, and a main nozzle 18. An earth electrode plate 28 is oppositely arranged to face against an electrical discharging electrode 25 arranged to have a predetermined spacing against a flame port 15 of the burner plate 16, thereby the earth electrode plate 28 may act as a buffle member against the gas injected from a flame port 15. Gas accumulation part is formed between the flame port 16 and the earth electrode plate 28, thereby the gas is kept at a concentration of gas suitable for an ignition of the gas. Due to this fact, it becomes hard to be influenced by an air flow within the combustion chamber and an igniting characteristic of the gas is not deteriorated under a lean concentration of the gas as found in the prior art and thus a positive igniting performance can be assured.

IPC: C23C14/24
Filed: 1989-06-09
Abstract: PURPOSE:To produce a uniform thin metallic film with high degree of completion by using a crucible made of heat-resisting material in which contact angle with respect to a molten vapor deposition material is regulated to a specific value. CONSTITUTION:As a vapor deposition material, a magnetic material of Co-Cr or Cr-Ni is used. Further, a crucible 9 in which contact angle with respect to a molten magnetic material 8 is regulated to >=90 deg.C and which is formed of a heat-resisting material composed principally of yttria or boron nitride is used. Foreign matter 14, such as oxide, introduced at the time when a vapor deposition material supply rod 12 is supplied is trapped on the wall of the crucible 9 owing to the slope due to swelling in the central part of the molten metal 8 surface and the interfacial tension between the crucible 9 and the molten metal 8, by which the admission of the foreign matter 14 into an evaporation region A can be prevented. Accordingly, the occurrence of splash can be prevented, and a thin film with high degree of completion can be obtained.
