A centrifugal tumbling granulating apparatus 1 comprises a fixed wall 7 having a grain contact portion 7a which is in contact with powder grains 2 and of which a horizontal section is formed in a circular shape, and a rotating disk 5 provided a clearance 12 away from an inner side of the fixed wall 7 and rotating in a horizontal direction by a motor 13, wherein an air supply device 21 for supplying drying air 22 to an upper surface side of the rotating disk 5 is provided above the rotating disk 5. The air supply device 21 has a cylindrical straight tube portion 25, and an air supply port 23 formed in a cone shape, and is disposed in a centrifugal tumbling chamber 6 to be movable in an up-and-down direction. During a granulating step, the air supply device 21 stops to supply the dry air 22 and waits at an upper position H. After the granulation processing, the air supply device is lowered at a lower position L and supplies the dry air 22 onto the rotating disk 5 to dry granulated substances. As a result, the granulating apparatus capable of efficiently obtaining, in a single apparatus, spherical particles of which each particle size is small and which exist within a narrow range of particle size distribution and of which deviation from spherical form is small is provided.

Pulsation, vibration and noise of a screw compressor is caused by compressed air abruptly discharging through a discharge port in a rotor chamber during rotation of a pair of rotors. The inside opening shape of the discharge port is within two tip curved lines drawn by the pair of rotors and coincides with the two tip curved lines at least at one point when fluid starts to discharge. In one embodiment, the inside opening shape is triangular with a vertex at a point of intersection of the two tip curved lines and a base side along the discharge end face of the rotor chamber. With this, when the air compressed in the compression chamber discharges from the discharge port, the discharge opening area of the discharge port smoothly increases. This reduces the pulsation of the discharged air and thus reduces the vibration and noise of the screw compressor.

A vehicle sunroof has a tilting lid provided at a front part of an opening formed in a roof of a vehicle. The tilting lid is adapted to be moved vertically at a rear end thereof with lifter mechanisms. A sliding lid is provided at a rear part of the opening supported by sliders adapted to be moved along guide rails disposed on both side edge portions of the opening and is constructed so as to be moved longitudinally through such movements of the sliders. The lifter mechanisms are provided in such a manner as to be oriented laterally at portions facing a rear end of the tilting lid on a laterally oriented cross member disposed so as to extend between front end portions of the left and right guide rails.

When a plurality of players play a simulation game in a plurality of user stations connected to a single game management station via a network, each player is not restrained in a game space over a lengthy period of game time while maintaining the reflection of a strategic intention of each player on the progress of a game. A process for player character selection enables the strategic character selection reserved at a suitable point of time by player character selection reservation system to be the effective selection only at a point of character encountering time appearing every fixed period of time. A player character encountering event decision system enables the strategic search route setting reserved at a suitable point of time by a player character encountering event reservation system to be the effective setting only at a point of character encountering time appearing every fixed period of time.

A catalytic combustion type heater set so as to reduce the exhaust emission at the time of ignition and the time of extinguishment by, at the time of ignition, providing a precombustion period and making the amounts of the fuel and air fed larger than the air-fuel ratio of the steady combustion period to prevent incomplete combustion and by, at the time of extinguishment, stopping the feeding of fuel and feeding only air in an amount lower than that before the fuel stops being fed so as to completely burn the remaining fuel, then feeding purging air.
摘要:
A crusher which is simple in structure and capable of dismantling a building structure and recovering iron material from among dismantled remains of a building. A movable jaw is provided so as to be opened and closed relative to a fixed jaw fixed to the crusher main frame. A magnetic case made of a nonmagnetizable material is provided on the bottom of the main frame. A permanent magnet assembly is slidably mounted in the case. The permanent magnet assembly is connected to a hydraulic cylinder for sliding the permanent magnet. By actuating the hydraulic cylinder, the permanent magnet will move down so that iron material is attracted through a bottom plate of the magnet case. By raising the permanent magnet assembly, the magnet weakens, so that the attracted iron material drops by gravity.

摘要:
An etching method for a silicon substrate, which can easily smooth the etching surface of the (110)-oriented silicon, is disclosed. A container is filled with KOH solution. In the KOH solution is immersed a (110)-oriented silicon wafer having a PN junction and is also disposed a platinum electrode plate to face the silicon wafer. To between a platinum electrode of the silicon wafer and the platinum electrode plate are connected a constant voltage power source, an ammeter and a contact in series. A controller starts etching from one surface on which the PN junction is formed, and terminates voltage application when the specified time lapses after the formation of an anodic oxide film is equilibrated with the etching of the anodic oxide film on the etching surface on the PN junction part. In this case, the controller detects flowing current through the ammeter, and the point of time when the equilibrium state is obtained is the point of inflection of the detected current to the constant current after the peak thereof.
