IPC: B24B5/18
Filed: 1987-11-20
Abstract: PURPOSE:To grind a workpiece in stable manners even during grinding by installing a receiving plate having the second supporting surface for supporting the workpiece in inclination so that the ground surface at the top edge part of the workpiece which is formed in the initial period of grinding on the inlet side of an abrasive wheel contacts the first supporting surface of the receiving plate over the grinding length. CONSTITUTION:The interval between an abrasive wheel 1 and an adjusting wheel 2 is set a little larger on the inlet side than on the outlet side, in consideration of the grinding quantity of a workpiece W to be ground and the length of the workpiece, and the workpiece W is sent onto a guide plate 6 on the inlet side, and when the top edge part of the workpiece W is introduced into between the both grindstones, a ground surface Wa having a small taper is formed on the top edge part. In this case, the workpiece W is supported onto the second supporting surface 4a of a receiving plate 4 which is set at a proper tilt angle (alpha). Therefore, the ground surface Wa is exactly attached onto the first supporting surface 3a of the receiving plate 3, and the grinding resistance which is received during grinding is supported in stable manners over the grinding length L by the supporting surface 3a, and the workpiece W is grinding-worked with high precision without generating chattering, and discharged from an outlet side guide plate 7.

Title: Granular body level detector and developing device
Inventor: WATANABE TAKASHI
IPC: G03G15/08
Filed: 1990-10-30
Abstract: PURPOSE:To avoid impaired precision even after long use by installing a granular body the surface of a roller which is rotatably mounted on a preset position on a casing member housing a granular body, and detecting the existance of the granular body by the sensor. CONSTITUTION:When a toner 1 exists in a casing 3, a toner sensor 10b which is fitted on the surface of a roller 10a does not detect the toner 1 during passing through the upper part where the toner 1 does not exist and detects the toner 1 during passing through the lower part where the toner 1 exists, and a control means 10d counts a time (t) when the toner sensor 10b is present in the toner 1 to calculate the height of the toner 1. The control means 10d rotationally moves a cam 93 corresponding to the calculated height of the toner 1 to restrict a layer thickness restricting means 9. It is thus possible to prevent the granular body from impairing detecting function.
