Title: Manufacture of fixed magnetic apparatus
Inventor: MATSUHASHI TAKEO
IPC: B23Q3/15
Filed: 1989-06-30
Abstract: PURPOSE:To facilitate assembling work by magnetizing a switching member before an operating knob for rotating the switching member made of permanent magnetic material is engaged with the switching member. CONSTITUTION:The lower end surface of a magnetic member 24 of a magnetic circuit block 22 acts as a magnetic acting surface 28. A switching member 32 made of permanent magnet is arranged in a bore 30 so as to be able to rotate. In the state where a recessed part 32b is positioned so as to stretch in the direction perpendicular to the magnetic acting surface 28, the switching member 32 is weakly magnetized, and acts as a weak permanent magnet in the diameter direction. A pinching member 76 is coupled with the bore 30 via a base member 36. According to this constitution, when the block 22 does not reach magnetic equibrium, the magnetized switching member 32 is rotated toward non-magnetized position where the block 22 turns to a magnetic equibrium state, so that the rotating position with respect to the block 22 becomes always constant. Hence the relative position relations and the like between the switching member 32, the base member 36, a plate 58, the block 22 and the pinching member 76 are not necessary to be corrected, and the assembling work is facilitated.

IPC: G03G15/20
Filed: 1989-06-29
Abstract: PURPOSE:To prevent a heating body from being broken by providing a pressurizing detection means and stopping the heat generation of the heating body in the case that pressure applied to the heating body by a pressurizing member is equal to or under a specified value. CONSTITUTION:The specified value which is previously converted to the pressure corresponding to a temperature detected by a temperature sensor 10 which detects the temperature of the heating body 12 is stored in a memory 20. A resistance value fetched in an MPU 19 is compared with the specified value in the memory 20, and when it is smaller than the specified value, that means, the pressure is larger, it is judged that the heating body is normal and a pressurizing body is driven. When the resistance value is larger than the specified value with some cause, that means, the pressure is smaller, a driving pulse for the heating body 12 is stopped to stop the heat generation(heating) of the heating body 12. Thus, the heating body 12 is prevented from being broken caused by local temperature rise.
