Title: Rotary head cylinder device
Inventor: KANEKO NORIAKI
IPC: G11B5/52
Filed: 1990-01-16
Abstract: PURPOSE:To suppress the change of a pre-load due to the temperature change of a bearing system by applying the pre-load on a pair of outer rings directing outside in an axial direction relatively without using a coil spring and an elastic member, etc. CONSTITUTION:The pre-load is applied to a pair of outer rings 71, 72 directing outside in the axial direction relatively for a rotary shaft 55. In other words, the bearing outer ring side direction of a line connecting the contact points of the inner and outer sides of the balls 76, 77 is inclined in the inside direction of a bearing, and a contact angle reversed from a conventional one is formed. Therefore, the pre-load in thrust directions C, D can be increased when temperature is increased, while, the pre-load in a radial direction can be reduced by temperature rise similarly as in a conventional system. Thereby, the amount of change of pre-load in both directions can be offset, which suppresses the amount of change of pre-load as a whole.

Title: Exhausting device for combusting device
Inventor: SHIMODAIRA TATSUROU
IPC: F23L1/00
Filed: 1982-01-19
Abstract: PURPOSE:To prevent the dew condensation in an exhaust gas duct after heat exchanging by the use of preheated bypass air. CONSTITUTION:An inner cylinder 17 surrounds a heat exchanger drum 15 and has an air inlet port 18 at the lower part. The upper part of the inner cylinder 17 is formed in an exhaust hood 20 with an exhaust port 19. The exhaust hood 20 is adapted to gather exhaust gas from the heat exchanger drum 15 and send it to an suction port of an exhaust fan 21. In this instance, the heat exchanger drum 15 and the inner cylinder 17 are arranged with a certain gap therebetween. A part of the air flowing from the air inlet port 18 flows through thus defined gap whereas the rest of air flows into another inlet port 16, both consumed in the combustion. The exhaust gas joints in the exhaust hood 20, and is mixed and stirred by an exhaust fan 21 and then exhausted outside the device out of an discharge port 22. Thus the dew condensation in the exhaust gas duct after the heat exchanging can be prevented.

Title: Method and apparatus for measuring concentration of suspended particles
Inventor: ZAITSU YASUSHI
IPC: G01N21/59
Filed: 1991-01-25
Abstract: PURPOSE:To measure the concn. of suspended particles without lowering measuring accuracy by preventing the adhesion of the suspended particles to the optical windows of both of a projection part and a detection part when the lowering degree of visibility due to the particles such as dust suspended in air is measured. CONSTITUTION:The attenuation quantity of light due to the particles bonded to an optical window is measured by temporarily removing the optical window from a light path and the measured value is corrected on the basis of the attenuation quantity and, only at the time of correction, a correcting optical window can be inserted in the light path in place of a measuring optical window. The attenuation quantity of light is calculated from the ratio of the intensity of the light reaching a photodetector before the optical window is removed from the light path and the intensity of the light reaching the photodetector after the optical window is removed from the light path by an apparatus equipped with an electronic circuit efficiently performing the above mentioned operation and, since the intensity of the light reaching the photodetector when the optical window is returned to the light path obtained using the attenuation quantity as a correction factor is the intensity obtained when the effect of the contamination of the optical window is corrected, by calculating transmissivity or an absorption coefficient based on the intensity of light, accurate measurement can be performed without generating an error.
