摘要： PURPOSE:To enhance the reliability of a rotor blade by fitting a ceramic blade having a dove-tail shape root part, in a metal disc or a shank, and by lowering the rigidity of end parts of a pad so as to restrain stress concentration in the contact end parts. CONSTITUTION:Each of pads 3 intervening between a ceramic blade 1 and a shank 2 is thinned around its contact end parts. Accordingly, the rigidity of opposite end parts of the pad 3 which are contact end parts lowers and according the contact end parts of the pad 3 does not become a part where a significant stress point exists even though a centrifugal force is applied to the ceramic blade 1 during nominal operation so as to avoid damaging the blade. Instead of thinning the end parts of the pad, grooves may be formed in the end parts of the pad, or only the end parts of the pad may be made of materials having a low rigidity.

摘要： PURPOSE:To provide a highly reliable backwashing apparatus for a gas dust removing device by preventing the leak of the compressed gas from a valve to conserve the consumption of said gas and preventing the cooling of the filter caused by the leak of the compressed gas to prevent the heat shock damage of the filter. CONSTITUTION:A compressed gas supply source 9, an upstream side valve composed of a low responsive valve, a gas sump space 12, a downstream valve 8 and a compression gas jet orifice 6 are successively connected by pipings from an upstream part and the volume of the gas sump space 12 is set to a size sufficient to store compressed gas necessary for one backwashing operation. By this constitution, the valve of a backwashing apparatus can be constituted only of an inexpensive low responsive speed valve having reliability and the downstream valve can also be replaced during the use of a gas dustproof device.

摘要： PURPOSE:To improve the strength, by forming the base of a wing in a dovetail, forming a groove at the periphery of a disk to fit to the base, and gearing and fixing the base of the wing to the groove with a heatproof adhesive. CONSTITUTION:This ceramic impeller 11 consists of a wing 12, a disk 13, and a rotary shaft 14. The base 12a of the wing 12 is formed in a dovetail, and at the periphery of the disk 13, a groove 13a is formed to gear with the base 12a. The base 12a is geared with the groove 13a of the disk 13, and fixed through a heatproof adhesive 15. Therefore, an excellent strength can be obtained against a tensil force from a centrifugal force.

摘要： PURPOSE:To prevent damage of a moving vane, by a method wherein a moving vane made of ceramic is held between the nip formed by the support parts of vane lock bodies located in grooves in the outer perphery of a disc. CONSTITUTION:A vane lock body 3 is engaged with a groove 1 in the outer periphery of a disc 2, and a moving vane 4 is held between the nip formed by adjoining support parts 14, formed in a claviform shape in cross section, of the vane support body 3. This, even if the vane is brought to a condition in which thermal stress and mechanical stress are produced, enables relieving of such stress, resulting in the possibility to prevent damage of a moving vane made of ceramic.
摘要翻译：目的：为了防止活动叶片的损坏，通过将由陶瓷制成的移动叶片保持在由位于盘的外部的凹槽中的叶片锁定体的支撑部分形成的辊隙之间的方法。构成：叶片锁体3与圆盘2的外周的槽1接合，活动叶片4被保持在由相邻的支撑部14形成的夹持部之间，形成为横截面的棒状这样，即使使叶片处于产生热应力和机械应力的状态，也能够缓解这种应力，从而可以防止由陶瓷制成的活动叶片的损坏。

摘要： PURPOSE: To prevent high-temperature process gas from lowering its temperature, by providing such a circuit that cooling gas which is fed to a cooling gas flow section is collected and cooled, and thereafter, is recirculated to the cooling gas flow section.
CONSTITUTION: Cooling gas is fed to a cooling gas flow section 31A to cool a rotor 1, and is itself heated. The heated cooling gas is collected through an outlet 8 and is cooled in a cooler 17, and thereafter, is sucked through a circulating fan 12, and is recirculated through an inlet 6 to a process gas flow section 30. This circuit is entirely closed, excepting a gap 22 opened to the process gas flow section 30. Further, the circuit concerning a cooling gas flow section 31B is also entirely closed, excepting a gap 23 opened to the process gas flow section 30.
