IPC: A61C3/02
Filed: 1987-07-22
Abstract: PURPOSE:To obtain a chuck free dental handpiece, by mounting a rotary member, wherein a grinder is fixedly provided to the lower end of a shaft equipped with a turbine blade, in a head part through upper and lower bearings. CONSTITUTION:The rotary member A of a dental handpiece is constituted so that a grinder 3 is fixedly provided to the lower end of a shaft 1 equipped with a turbine blade 2, and bearings 4, 4 generating high speed rotation at the time of load and indispensable to keep said rotation are mounted to the upper and lower parts of the turbine blade as an integrated structure.

Abstract: PURPOSE:To attain the simultaneous data collection from lots of slave stations in a short time while adopting a conventional random access system by allowing a master station to control the mode of use of each slot of a line from the slave stations to the master station. CONSTITUTION:The master station requests the transmission of data to slave stations No.1-No.5 by using a message 15. Slave stations other than the slave stations No1-No5 designated as above stops the data transmission by the random access being the normal operation. Only the slave stations No.1-No.5 use the 5 slots of the next frame to transmit the transmission of data in a predetermined order without any collision. Since the data from the slave stations do not collide with each other, the data are received correctly by the master station and the master station uses a message 16 to give the data transmission request to the next groups No.6-No.10 without awaiting the data reception from the slave stations No1-No5.
