Patent JP-S59225208-A (JP)
Title: Combustion method
Inventor: YOSHIKAI HIDEHISA
IPC: F23N1/02
Filed: 1983-06-07
Abstract: PURPOSE:To reduce production of NOx while the production of an unburnt content is continuously controlled to a low level, by a method wherein, based on information in response to the combustion state of a burner, injection of the air through an after air port is controlled so that the air is well mixed with burner combustion gas. CONSTITUTION:A computer 28, which, based on the information (signal) 29 answering to the combustion state (ignition and extiguishment) of a burner, outputs their respective driving signals to air damper driving devices 24-27, is located between an NOx value setter 23 and each of the air damper driving devices 24- 27. Even in case the number of combustion devices is varied, this enables the increasing rate of an unburnt content to be controlled to a low level. The after air amount at a front side wall and a rear side wall is caused to be varied according to a change in the number of the combustion devices, and this keeps mixture of an after air and combustion gas in a best condition at all times, resulting in the possibility to employ a two-step combustion method or a furnace denitrating method without increasing the unburnt content and to reduce production of NOx in exhaust gas.

Title: Atom oscillator
Inventor: ONOE TAKAAKI
IPC: H03L7/26
Filed: 1985-05-10
Abstract: PURPOSE:To prevent the inconvenience of Cs flowing out to a heat section by overlapping a slit between a beam source storage section and the heat section so that each throughhole of plural transmitting plates having the throughhole is deviated mutually and passing through only the Cs vapor in zigzag through each throughhole and a minute gap. CONSTITUTION:The 1st slit plate 41a, the 2nd slit plate 41b and the 3rd slit plate 41c as the transmission plates provided with slit shaped throughholes are overlapped in a way that the slit throughholes are deviated mutually to provide a composite slit part 41 between a beam source storage part 24 and a heat part 27. The liquidified Cs by heat conduction from the heat part 27 flows into the beam source storage part 24 and the Cs is vaporized by the composite slit part 41 heated by the heater 25 of the heat section 27. Then the Cs is passed in zigzag through the slit through hole and minute gaps between the plates of the slit plates 41a, 41b and 41c and irradiated to the cavity resonator as a Cs atom beam 30 through a collimator 26. Thus, it is prevented that the liquidified Cs 22 flows to the heat part 27 through the collimator 26 carelessly.

IPC: H01L21/68
Filed: 1984-05-18
Abstract: PURPOSE:To eliminate vibration of a semiconductor wafer in a wafer cassette by holding the cassette so that the wafer has an inclination with respect to a gravity direction. CONSTITUTION:A truck 8 engaged at a carrier with a guide rail 1 and a base 9 to become a base of latches 3, 4 for holding a cassette are provided, and the base 9 is variable at the angle with respect to the truck 8. This angle is set to zero when the wafer cassette 5 is detachably attached via the latches 4, 5, and to 5-45 deg. after holding the cassette 5. Thus, since the wafer is inclined at 5-45 deg. with respect to the gravity direction, it is contacted with one of the groove of the cassette, and vibration can be eliminated in the groove when the carrier is operated or stopped. Thus, preferably conveying can be performed without generating dusts.

More preferably, the relative dielectric constant of the dielectric substrate 5 is higher than 40, and waveguide 1, reflector 3 and radiator 2 composed of the conductor thin film are formed by a depositing thin film and/or a plating thin film. Thus, the microwave antenna element with more satisfactory miniaturization and flat directivity can be obtained.
