A coal mill introduces raw coal between a roller and a ring and pulverizes the raw coal. A reduction gear for a mill is provided in a lower portion of the coal mill. A cooling fan is mounted to an input shaft of the reduction gear for the mill which is connected to a motor. A radiator for cooling a lubricating oil which lubricates within the reduction gear for the mill is arranged in an extending portion of the input shaft. An oil pump and a line filter are provided in a lubricating passage which supplies the lubricating oil to the radiator, and a flexible pipe connects between these elements. Accordingly, the coal mill is cooled by air.

In a reproduction camera having a slant body and anteroinferior platforms, apparatus for setting or replacing a copy comprises a carrier which is anteroinferior and capable of moving along the slant body, where the optical axis is always vertical thereto, a copy holder which is mounted on the carrier to swing back and forth around a fulcrum, and a plate for holding down evenly a copy mounted on the copy holder by a hinge, by which the plate can be opened or closed. The fulcrum is positioned so that the total centroid of the combination of the holder, the plate and the hinge exists in the rear of the fulcrum when the plate is opened and exist in the fore of the fulcrum when the plate is closed.

The present invention relates to a bearing used in a transmission. The radial bearing for supporting a rotating shaft of the transmission has a substantial elliptical-cylinder-shaped inner circumferential surface. At least two lubricating resin members are provided on the inner circumferential surface so that the members are extending in the axial direction and symmetric with respect to the central axis of the bearing. The rigidity of the bearing is increased as increasing the rotation speed of the shaft.

A cooling device is provided for a light source in a copying machine, wherein the generation of air seemingly waving due to heat is prevented by effectively cooling a lamp body for lighting an original effectively in order to obviate the deterioration of an optical image.Light pervious heat-shield members are disposed at suitable intervals in an irradiation opening of the lamp body accommodating light source bulb and a reflector therewithin so as to enable blowing of ambient air past and between these members. At least the member positioned at the side of the light source bulb is composed of a heat-ray absorption glass. Air flow is guided through the chamber accommodating the light source bulb so that it may perform a forced air cooling of the inside of the lamp body in order to prevent the generation of the air waving due to heat from the lamp.

A gas exchange apparatus for use as a artificial lung incorporates a hollow fiber module for bundling a plurality of thin-walled hollow silicone fibers. The fibers are wound in the form of a twilled pattern so as to form an internal perfusion passage and an external perfusion passage. A housing encloses the hollow fiber module. The housing incorporates a first inlet and outlet formed on the housing for communication of gas or liquid with the internal perfusion passage, and a second inlet and outlet formed for communication of gas or liquid with the external perfusion passage.

A reduction mechanism for mill comprises a planetary gear train comprising a sun gear, planet gears, an internal gear and a carrier for supporting the planet gears; an input shaft for feeding power; a sun gear shaft on which the sun gear is mounted; an intermediate shaft interposed between the sun gear shaft and the input shaft; an output table for transferring rotary power; a thrust bearing for supporting the output table; and a case for enveloping the planet gear train and the thrust bearing. A tilting pad type bearing is used for the thrust bearing. The thrust supporting portion of the tilting pad type bearing is formed spherically. The center of the spherical surface is positioned between inside and outside diameters of a vertical portion of the case which receives a thrust force.

摘要:
In order to execute a series of moving sequences by synchronous and exclusive control of unit operations taught or programed in advance, there are provided a first storing of the relationship of the sequence of execution of each unit operation to other unit operations to be controlled synchronously or exclusively; a second storing of information relating to the operational status of each unit operation; and a third storing of operating instructions for executing each unit operation. When machine tools have stopped due to the occurrence of an abnormality while a series of unit operations are being executed by the operating instructions stored in the third storing means, a unit operation for restarting on the basis of the relationship of the executing sequence stored during the first storing is appointed, and information concerning the operational status stored during the second storing is corrected. Furthermore, at the time when a junction operation in which there exist two or more sequences leading to a unit operation has been executed, a fourth storing is effected during the normal state of the operation steps relating to that execution. Then the content of the information stored during said second storing is corrected to a state permitting restarting from an appointed unit operation by referring to information stored during the fourth storing.
