摘要： PROBLEM TO BE SOLVED: To solve problems in a conventional combustion apparatus wherein, since a distance between a negative electrode to which a voltage is applied and a lower burner is approximately 10 cm and accordingly a voltage of approximately 10 kV or higher is required to sufficiently vary the angle of a flame, it is difficult to reduce the size of a power circuit and also it is difficult to secure insulation between a combustion apparatus body and the electrode.
SOLUTION: This combustion apparatus comprises a combustion chamber 12, burners 13 and 14 installed in the combustion chamber, electrodes 22, 23, and 24 installed near the burners, and a power supply 16 for applying a voltage between the burners and the electrodes. The angle of the flames blown from the burners are varied by the application of the voltage from the power supply. Since the electrodes are disposed near the burners, the applied voltage required for varying the specified angles of the flames can be reduced to reduce the size of the power circuit and simplify a structure for insulating the electrodes from a combustion apparatus body 11.

摘要： PROBLEM TO BE SOLVED: To detect an initial-stage carious tooth in a subsurface demineralization state where the intensity of fluorescence radiated from a carious part is extremely small compared to that from a healthy part.
SOLUTION: This carious tooth detecting apparatus is provided with an irradiation means 10 for irradiating a tooth with light of a predetermined wavelength, a filter 14 for sorting out the wavelengths of light radiated from the tooth, an imaging means 15 for converting the light transmitting through the filter into electric signals, and an image display means 16 for displaying the state of the tooth from the imaging means as image information. The filter cuts out wavelength components of the irradiation light of the irradiation means 10 to remove reflected light of the irradiation wavelength and transmit only the fluorescence excited to a long wavelength side by the irradiation light out of the lights radiated from the tooth with the initial-stage carious part. This constitution displays the initial-stage carious part having the extremely small intensity of the fluorescence compared with that of the healthy part as a dark spot on the image so as to detect the initial-stage carious part.

摘要： PROBLEM TO BE SOLVED: To prevent a high frequency inverter from having withstand voltage breakdown and thermal damage even in a condition in which impedance matching is not satisfied.
SOLUTION: This high frequency heating arrangement is provided with: a dc voltage supply 1; the high frequency inverter 9 to generate high frequency; a power detecting circuit 14 to detect the output power of the high frequency inverter 9; a matching circuit 15; and a parallel-plate electrode 19. The dc voltage supply 1 is composed of a flyback converter 7 and a flyback converter control part 22, and when reflected power increases and impedances are not matched, the output voltage of the dc voltage supply 1 is kept low by making the oscillation frequency of the control part of the flyback converter high so as to lower the output voltage of the flyback converter 7. Thereby, the highly safe high frequency heating arrangement alleviating loss generated in the high frequency inverter 9 and preventing thermal destruction from being caused, is realized even in a condition that impedance watching is not satisfied.

摘要： PROBLEM TO BE SOLVED: To reduce a cost while attaining miniaturization by decreasing the number of turns of a winding without magnetically saturating a core. SOLUTION: Each one leg of the first core 25 and the second core 26 as a pair of the U-shaped cores is inserted into the central hole of a bobbin 24 on which the winding is wound. Front ends of the legs for the cores are fixed to the first gap 27 and the second gap 28 of the bobbin 24 by a core fixing means 29 so as to be abutted and opposed. The number of turns for obtaining specified inductance can be decreased by reducing the ratio of the first gap 27 inside the winding, which is positioned inside the bobbin 24 and to which magnetic flux is concentrated, and increasing the ratio of the second gap 28 outside the winding.

摘要： PROBLEM TO BE SOLVED: To provide a carious tooth detecting apparatus which can detect even an early carious tooth with subsurface demineralization even though the intensity of fluorescence emitted from a carious part is extremely small compared to that of fluorescence emitted from a healthy part of the carious tooth.
SOLUTION: The carious tooth detecting apparatus comprises an irradiating means 10 for emitting light of a predetermined wavelength to a tooth, a filter 14 for sorting out the wavelengths of light emitted from the tooth, a photographing means 15 for converting the light passed through the filter to an electric signal, and an image displaying means 16 for displaying the status of the tooth as image information using the photographing means. The filter 14 cuts out light having wavelength components of the light emitted from the irradiating means 10. More particularly, the filter 14 removes reflected light having the wavelength of the emitted light and passes only the fluorescence having an excitation wavelength longer than that of the irradiated light from among the light emitted from the tooth having an early carious part. With such a configuration, even an early carious part is displayed and detected as a dark spot on an image even though the intensity of fluorescence emitted from the early carious part is extremely small compared to that of fluorescence emitted from a healthy part.
