An apparatus for mirror-polishing a thin plate, wherein uniformity of tightness in a stretched condition across an elastic film can be achieved and a polishing pressure distribution on the thin plate is uniformalized, so that constant polishing stock removal is realized and high flatness polishing is made possible. In the apparatus, the thin plate is held on a thin plate support mounted on a rotatable press member and the thin plate is pressed to a polishing means by the press member, and the apparatus has features that a holding surface for the thin plate is formed by a flexible elastic film; the elastic film is fastened to the press member or a part mounted thereto in a condition that the elastic film is sandwiched between a spacer and a holding piece; and a pressure, which presses the thin plate held on the elastic film to the polishing means, is adjusted by applying a back pressure to the thin plate with a fluid feed means, while adjusting tightness of the elastic film by the space.

摘要:
A method for dynamically sharing an application in a conference system while maintaining state regardless of whether the application is under execution in all conference devices. The conference system includes a plurality of conference devices with at least one conference device executing an application program. The method for dynamically sharing the application program among the plurality of conference devices in the conference system while maintaining state, includes the steps of: communicating a request to share the application program from a requesting conference device which is executing the application to all enrolled conference devices; storing an executed state of the application program to be shared in the requesting conference device; starting the application program to be shared by enrolled conference devices in which an application program corresponding to the application program to be shared is not started; communicating the executed state stored in the requesting conference device to all enrolled conference devices; and processing by all enrolled conference devices of the application program to be shared in a shared executed state equal to the executed state communicated.

A motor pump group has a plurality of centrifugal pumps of the same nominal port diameter including a plurality of impellers having stepwise greater outside diameters for stepwise higher pump heads, and a plurality of respective motors for actuating the pumps. The pump heads are classified into a low head section and a high head section. The low head section is handled by a single-stage impeller, and the high head section is handled by multi-stage impellers. The centrifugal pumps have respective pressed-sheet pump casings. The outside diameters of the impellers are not required to be increased in the high head section, and the outside diameters of the pump casings fall in a relatively small range.
摘要:
The invention features flattening a sliced wafer in a thin disc-like form, and chamfered if necessary, through simultaneous double side grinding by passing the wafer through between paired cylindrical grinding rolls supported at both ends in bearings, and subsequently single side polishing or double side polishing the flattened wafer to obtain a polished wafer. A lapping step and an etching step in the related art thus can be dispensed with to curtail the process time. The grinding is done by simultaneous double side grinding, so that it is free from slice mark transfer due to vacuum suction of wafer to hold the wafer, or unlike a wax mounting system it does not involve complicated operation. Furthermore, instead of batch grinding, continuous grinding can be readily made. The process is thus free from working stock removal fluctuations and permits high flatness and stable thickness to be obtained by the grinding.
