A laminated glass according to an embodiment of the present invention includes a first glass plate, a second glass plate, and an interlayer film held between the first glass plate and the second glass plate. When a relative dielectric constant of the first glass plate is represented by ε; a relative dielectric constant of the second glass plate is represented by ε; a relative dielectric constant of a first interlayer film provided in a first region of the interlayer film is represented by ε; a reflection coefficient at an interface between the first glass plate and the first interlayer film is represented by Γ; and a reflection coefficient at an interface between the second glass plate and the first interlayer film is represented by Γ, the reflection coefficients Γand Γsatisfy relations 0.0≤Γ≤0.2 and 0.0≤Γ≤0.2.

Laminated glass

To provide an apparatus that may impart a complicated bend deformation to an object to be machined such as a ceramic bar elongated in one direction or the like, and may reduce the non-uniformity in machining amount of the object to be machined upon the machining work of the object to be machined, specifically a correcting mechanism for deforming the object to be machined together with a jig holding the object to be machined is provided in a machining apparatus. The correcting mechanism includes a base, a plurality of levers provided at first ends with pins, a shaft fixed to the base for rotatably supporting the levers, and a plurality of correcting drive means coupled to second ends of said levers for pivoting the levers to the shaft to thereby pivoting the pins. The jig includes a plurality of load receiving portions arranged in a holding portion elongated on one direction for holding the object to be machined whereby portions corresponding to the load receiving portion in the holding portion are deformed together with the object to be machined in accordance with pivoting of each pin.

Machining apparatus for workpiece and method therefor

When electric elements are formed on a ceramic bar or the like, the positional displacement of the respective elements occurs due to a division exposing process or the like. An object of the present invention is to provide a device and a method which unify the non-polished portion of the respective elements by conducting polishing while a complicated deformation or the like is given to the ceramic bar. To achieve this object, the ceramic bar or like is held by using a jig, and a plurality of loads are applied to portions of the jig where the ceramic bar or the like is held, to thereby deform the ceramic bar or the like and polish the element in that state. In this situation the load applied points are disposed so as to avoid the boundaries of the division exposure.

Magnetic head polishing device and method thereof

In the polishing work for forming a crown shape on a ceramic bar bearing a plurality of conversion units for the magnetic heads, the present invention is to provide a well-controlled satisfactory shape by pressing the ceramic bar, provided with plural grooves perpendicular to the longitudinal direction and on a surface opposed to the polished plane, to a substantially concave polishing plane through an elastic member principally composed of rubber, then measuring the magneto resistivity of an element provided in the conversion unit of the magnetic head, and adjusting the pressure at the crown forming operation by a closed loop control based on the result of such measurement.

Polishing apparatus for magnetic head and method therefor

An apparatus for lapping a workpiece including a plurality of magnetic heads supported by a tool is disclosed. The lapping apparatus comprises a rotary lapping table, a lapping head attachment frame, an adjuster ring resiliently supported by the frame, a lapping head attached to the adjuster ring, a tilting assembly attached to the lapping head, and an up and down movable back plate pivotally attached to the lapping head. The apparatus further comprises first actuators or cylinders for correcting balance by applying forces on right and left sides of the pivotal point of the back plate, and second actuators or cylinders for correcting bow of the workpiece by applying operating forces on a plurality of predetermined locations of the tool so that the moving directions of movable parts of the second actuator means are substantially parallel with the directions of the operating forces.
