Abstract: PURPOSE: To detect the conditions of a spindle and accuracy of truing or dressing by a method wherein a vibration detector is provided on a housing to detect the vibration of a grinding wheel spindle.  
     CONSTITUTION: The vibration detector 14 is fitted to an upper part of a spindle housing 8 for the grinding wheel 10 for internal grinding of a work W rotated on a head stock 4. An acceleration of vibration of the grinding wheel spindle 9 detected by the detector 14 is fed through an amplifier 16 into a band pass filter 17 to take out a primary component, which is converted into a root mean square (rms) value by an rms value processing part 30. The detected vibration is compared by a comparator 18 with a reference value set by a variable resistor 19. When the detected value is in excess of the reference value, a grinding operational control board 21 provides an indication of abnormality, and if the abnormality is in the grinding wheel, a command for dressing by a dressre 3 is given to a dressing device 12.

IPC: F25B1/00
Filed: 1991-07-12
Abstract: PURPOSE:To prevent a high temperature of brine after a holiday, and prevent an overload protector from operating in a temporary overload state by lowering capacity of a compressor when a refrigerant pressure becomes a high load state before reaching an overload state, and eliminating the low capacity operation within a predetermined time. CONSTITUTION:Pressure switches 25, 26 detects low and high pressures of a compressor 1, and operate when it exceeds the set value to protect against low and high pressures. A pressure switch 27 detects a high pressure of the compressor 1, and operates when it becomes a predetermined pressure or higher. The predetermined pressure is a lower value than the set value of the switch 26 and when the compressor 1 becomes an overload, and protects against a high load by the operation of the switch 27 by the value of the high load state before the compressor 1 becomes an overload. Since the compressor is operated with the low capacity for a predetermined time when the compressor becomes the high load state, the compressor does not reach the overload even if brine temperature is raised after a holiday, etc., thereby preventing stop of the operation due to the operation of an overload protector.
