Title: Method and apparatus for meauring radius of curvature of surface
Inventor: TAKAI MASAAKI
IPC: G01B11/255
Filed: 1992-12-24
Abstract: PURPOSE:To provide a method and apparatus for measuring a radius of a curvature of a surface to be measured by a simple structure without a driving mechanism. CONSTITUTION:A light from a light source 11 is converted into a parallel beam by a collimator 12 and is refracted by an electro-optical lens 13 to be emitted to a surface 14 to be measured. A voltage applied to the electro-optical lens is varied by a voltage-applying means 19 so that the inputted beam to the surface 14 to be measured is emitted to focus on a point (A). The beam reflected by the surface 14 overlaps with the inputted beam and goes in the reverse direction to take back to the light source 11. In this stage, when the intensity of the reflected beam becomes a peak level is realized from an output of a photodetector 17 so that a focal distance of the electro-optical lens 13 at that time is obtained. Next, the inputted beam is emitted to focus on a center of curvature (O) in the surface 14 so that a focal distance is obtained likewise. The difference of both of the focal distances is calculated to obtain a radius of curvature (r) of the surface 14 to be measured.

Filed: 1992-12-28
Abstract: PURPOSE:To prevent silicone oil for releasing from being attached to a paper and to prevent toner from being offset to the surface of a fixing roller in a heat roller system fixing device. CONSTITUTION:A metering blade 11 is constituted by adhering a metering rubber 11b to the tip part of a leaf spring blade 11a. By deflecting the blade 11a, the rubber 11b is made to press-contact with the fixing roller 1.

By setting the press- contacting force to a proper value, the metering of the oil for releasing is executed. Therefore, since the blade 11a of the metering blade 11 is made of a leaf spring, the press-contacting force of the blade 11 with respect to the roller 1 is uniformly generated in the width direction of the roller and the variation of press-contacting force distribution is eliminated.

Abstract: PURPOSE:To make a wire diameter constant and to improve quality by automatically controlling a wire drawing speed according to the wire diameter of a wire rod to be worked after passage through a die. CONSTITUTION:The wire rod W to be worked is drawn through the die 2 after heating by 2 heater 2 and is taken up on a winder 8. A wire diameter measuring instrument 11 measures the wire diameter of the wire rod taken up to be worked and outputs the measured diameter to a controller 12.

When the both values are not equal the optimum speed of the un-winder 5 is calculated in accordance with the difference between the both values and is outputted an inverter 7. The inverter 7 controls the number of revolution of a motor 6 to obtain the optimum speed of the un-winder 5 in order to regulate the measured value of the wire diameter to a set target value. Then, the wire rod W delivered from the un-winder 5 moves at the optimum speed for setting the measured value of the wire diameter at the target value of the wire diameter and is drawn.
