Title: Cutting tool having active vibration isolating function
Inventor: SUGITA YUJI
IPC: B23Q17/09
Filed: 1987-01-19
Abstract: PURPOSE:To prevent production of vibration between a workpiece and a cutting tool and to enable execution of a high speed cutting work, by a method wherein a voltage applied on an actuator is regulated by computing values of signals from a load detector a relative displacement detector between the load detector and a piezo-electric actuator. CONSTITUTION:When relative displacement between a workpiece 1 and a cutting tool 3 is fluctuated in a direction A due to vibration produced by a drive system 2, vibration propagated from the outside, or a change in a cutting force, an alternating force is exerted on a tool 3. An alternating force, propagated through a piezo-electric actuator 11, is detected by a load detector 12, simultaneously, relative displacement between a tip part 7 of the tool 3 and a root part 9 is detected by a displacement detector 13, and the alternating force and the relative displacement are inputted as a load signal and a displacement signal, respectively, to a computing device 14. When, by means of a calculated expansion and contraction amount, the actuator 11 is expanded and contracted, the alternating force propagating through the tool 3 is reduced to zero. Thus, vibration is absorbed by the tool 3, an alternating force produced between the tip part 7 and the workpiece 1 produces only the inertia force of the tip part 7 and is reduced to a low value, and a fluctuation in displacement between each of the tip part 7 and a diamond tip 8 and the workpiece 1 is decreased to zero.

Abstract: PURPOSE:To oxidate and remove oil drops attached, by forming a heater for cooking with a super heat resistant ceramic plate (plate heater) in which a heat emitting body is embedded, and providing an oxidation catalyst layer over the surface of this plate heater. CONSTITUTION:A low-expansion coating layer 9 of glass type is provided over the surface of a plate heater 7, and further thereover an oxidation catalyst layer 14 is furnished, which consists of mat-shaped baking of enamel material comprising frit and catalyst, which consists of Pt or Pd and oxide of rare earth.

When current is fed, the surface temp. of the heater becomes substantially uniform at 600-700 deg.C. This prevents uneven baking even though the plate heater 7 approaches the material to be cooked, and eventually sputtered and attached oil drops to the surface of this heater 7 will be oxidated insantly by the oxidation catalyst layer 14 to ensure that the surface is kept purified and free from baking-fast.
