Title: Lens grinding device
Inventor: MIZUNO TOSHIAKI
IPC: B24B9/14
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To precisely work a large quantity of lenses in a short time by providing a control means for controlling the movement by a lens rotating axis moving means and a grinding wheel axis moving means by a machining data. SOLUTION: While the rotating torque quantities of servo motors 310R, 310L are monitored by a control part 600, lateral rough grinding wheels are moved toward a lens to be worked while rotating, whereby the lens is gradually ground from two directions. The lateral moving quantities on the lens side of the rough grinding wheels are independently controlled on the basis of lens frame form information. The rough grinding is completed until the lens to be worked is rotated 0.5-1.5 times on the basis of the thickness of lens edge and grinding quantity, and the grinding can be thus performed in a short time, compared with a grinding from one direction by one axis.

IPC: B23B5/00
Filed: 1991-04-26
Abstract: PURPOSE:To prolong the life of the cutter for a tip dresser. CONSTITUTION:A single cutting edge 6d which cuts the front end face of the tip is so formed in the flat part 6a of a cutter 6 facing the front end face of the tip as to extend in a prescribed diametral direction with the center O of rotation as a start point.

IPC: G02F1/133
Filed: 1985-05-10
Abstract: PURPOSE:To obtain the orientation controlling layer capable of uniformly controlling the orientation by incorporating a specific imide polymer to the orientation controlling layer. CONSTITUTION:In the titled element comprising the substrate, the means for impressing an electric field, the orientation controlling layer and the ferroelectric liquid crystal layer, the orientation controlling layer is comprised the polyimide polymer having repeating units shown by the formula. As the polyimide polymer has the imide bond, the polymer is insoluble to water. So that, the preferable method of forming the imide type high polymer film on the substrate lies in dissolving a polyamide acid to a solvent followed by coating the substrate with the obtd. acid solution, and by thermal-treating it to form the imide bond with a dehydration and a ring closure. The polyamic acid which is a precursor of the polyimide is usually synthesized by condensating an anhydride of a tetracarboxylic acid and a diamine. The condensation is performed at a temp. of <=50 deg.C under a anhydrous condition.

Filed: 1987-04-23
Abstract: PURPOSE:To always monitor whether or not a sensor is effective by being equipped with an amplifying circuit to amplify the noise component of a piezoelectric element and when the rectifying value of a noise component comes to be a prescribed value or above and detecting the disconnection of the piezoelectric element. CONSTITUTION:An amplifying circuit 91 to amplify the noise component of a piezoelectric element, a rectifying circuit 92 to rectify the output of the amplifying circuit 91, and a comparing circuit 93 to compare the output signal of the rectifying circuit 92, a signal to amplify this with a reference value Vcc are equipped. The rectifying value of the noise component is the prescribed value or above, and thus, the disconnection of a piezoelectric element 90 is detected. Thus, since the disconnection condition of the piezoelectric element can be judged by the noise, when the piezoelectric element is used for a sensor, etc., it can be always monitored whether or not a sensor is effective. Thus, for example, when the influence given to the inspection by the disconnection is larger like the head of the surface inspecting device of a disk board, the effectiveness/ineffectiveness of the sensor can be grasped at real time and the efficient measurement can be executed.
