Title: Method and device for positioning cylindrical base material
Inventor: OHIRA AKIRA
IPC: B05D1/18
Filed: 1995-05-24
Abstract: PURPOSE: To perform positioning without damaging a cylindrical drum and to prevent a positional shift in the connection part between mutual cylindrical drums by specifying a fluid amount per minute of a fluid discharged in the gap between the surface of a cylindrical base material and the discharge port of a spraying means opposite thereto. CONSTITUTION: Discharge ports 25 are opposed to the peripheral face of a cylindrical base material while keeping a gap G. The gap G is 20μm-3mm. When the gap G is smaller than 20μm, the discharge ports 25 are brought into contact with an inner cylinder part 22 and the cylindrical base material is easily damaged. Further, when the gap G is larger than 3mm, positioning precision of the cylindrical base material is lowered. Fluid amount per minute supplied to air supply ports 23 is desirably 0.1-50m<3> /min. When it is smaller than 0.1m<3> /min, precision of the position of the cylindrical base material is deteriorated. When it is larger than 50m<3> /min, the stacked cylindrical base materials are vibrated and liquid film is made uneven. Thereby, generation of a flaw on the surface of the cylindrical base material is eliminated and positioning precision is enhanced.

Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To eliminate or reduce influences on a crew by muting ringer tones sent from a base station to a mobile station or suppressing their sound volume when the base station performs data communication to acquire movement information from the mobile station. SOLUTION: A base station 6 makes a telephone call to a mobile station 5 to acquire movement information including the progress of a job, etc., stored in a movement information input part 52 of the station 5. Then synchronization of a modem 62 is confirmed after connection of a telephone circuit and call tones ring at the station 5 in a normal state. The above, however, may possibly hurt crews. Thereby, a prescribed time is inputted via the part 52 of the station 5 and accordingly a call control time setting part 53 sets a ringer tone control time in a data communication incoming mode. Thus, the ringer tones are muted during the ringer tone control time. If the data communication exceeds the ringer tone control time, the ringer tones are generated. Meanwhile, the station 6 produces a command to mute the ring tones of the station 5 or to suppress the sound volume of these tones.  As a result, the crew of the station 5 are not disturbed data communication.
