Abstract: To provide a glass roll capable of reliably preventing a glass film from breaking from an end surface of the glass film as an origin of breakage, a glass roll (1) is formed by winding a glass film (2) into a roll while superposing the glass film (2) on a protective sheet (3), the glass film (2) being formed by an overflow downdraw method to have a thickness of 1 ?m or more and 200 ?m or less, and to have each end surface in a width direction to form a cut surface cut by laser splitting.

Abstract: A glass film laminate includes a glass film, a supporting sheet fixed on one surface of the glass film so as to protrude from the glass film and having a stretch ratio of 10% or less under a tensile strength of 50 MPa, and a protective sheet peelably laminated on the other surface of the glass film so as to cover edge portions of the glass film.

Abstract: Provided are a glass film laminate having a glass film, a support sheet laminated on one surface of the glass film to extend off the glass film, and a protective sheet peelably laminated on the other surface of the glass film to cover the edges of the glass film, and a glass roll produced by winding the laminate.

Abstract: The present invention provides a depopulation version hard disk drive apparatus that has a reduced number of magnetic heads and suspension arms from a standard hard disk drive apparatus, wherein the magnetic head can still be properly controlled during a loading state. The hard disk drive apparatus includes a ramp which interfaces with the suspension arm when loading and unloading the arm. An angle of a second slope surface 61c of the ramp in the depopulation version hard disk drive is set larger than that of the corresponding slope surface of the ramp 6 the a standard version hard disk drive.

Abstract: A detection hole is formed in a belt. When the detection hole arrives at the reference/edge sensor, the light from the reference signal detection light emitting element passes through the detection hole, and then arrives at the reference signal detection light receiving element. The controller operates so that data is transmitted to the laser scanner units at the wiring timing of each data based on the reference signal. Furthermore, the reference/edge sensor has another pair of light emitting and receiving elements, i.e., an edge signal detection light emitting element and an edge signal detection light receiving element. The belt is so attached that its end portion can always remain within a detectable area. In addition, corresponding to an area in which the belt shields a detectable range, it is possible to obtain an edge signal changing in analogue manner. In accordance with a change of the edge signal, the controller can thus control a steering roller.

Abstract: A method of fabricating a semiconductor device is provided wherein a first semiconductor substrate is prepared with a first insulating film formed over a first main surface of the first semiconductor substrate, s semiconductor film of n-type conductivity formed over the first insulating film, and a second insulating film formed over the semiconductor film so as to cover the first main surface. A second semiconductor substrate is also prepared with a third insulating film formed over the second semiconductor substrate. Next, the second insulating film and third insulating films are bonded together by thermal processing to join the first semiconductor substrate and the second semiconductor substrate. A portion of a second main surface of said first semiconductor substrate, opposite to said first main surface of the first semiconductor substrate is then removed to expose a portion of the first semiconductor substrate, thereby providing a semiconductor layer.
