To provide a method for tempering glass to obtain tempered glass having high surface quality and a deep compression stress layer. The present invention relates to a method for tempering a glass plate comprising a preparation step of preparing a glass plate having a surface temperature of at most the strain point, an internal heating step of heating the internal temperature of the glass plate to be at least the annealing point, while maintaining the surface temperature of the glass plate within 10 minutes, or to be at most the strain point, and a cooling step of cooling the glass plate.

A glass sheet processing method is provided for irradiating a laser beam on a glass sheet and forming a cleavage in the glass sheet with thermal stress. If each of an irradiation area of the laser beam on the surface and an irradiation area of the laser beam on the back face of the glass sheet includes a peak position of a power density of the laser beam, each irradiation area has an asymmetrical power density distribution that is asymmetrical with respect to a reference line that passes through the peak position and is parallel to a moving direction of the peak position. If each irradiation area has no peak position, each irradiation area has an asymmetrical shape that is asymmetrical with respect to a reference line that passes through a centroid position of the irradiation area and is parallel to a moving direction of the centroid position.

Glass sheet processing method and glass sheet processing apparatus

A method for processing a glass sheet includes a scribing step of heating a part of a glass sheet with laser light which is transmitted through the glass sheet from a first main surface of the glass sheet to a second main surface of the glass sheet, and moving an irradiation position of the laser light on the glass sheet, thereby forming a scribe line on at least the second main surface of the glass sheet.

An aircraft ice protection system is provided for preventing ice accretion on a wing of an aircraft or removing the accreted ice. Bleed air extracted from a main engine of the aircraft and air introduced from an air intake installed on an airframe and heated by a heat source of the airframe of the aircraft are selectively supplied to a hot air chamber formed inside the wing, thereby carrying out ice protection.

It is an object of the present invention to make it possible to use the same inspection apparatus regardless of the difference of the model of the glass sheets. The present invention comprises a step of irradiating a surface of a glass sheet G with light from a patterned light sourcehaving a specific pattern, a step of picking up an image of the glass sheet G, a step of analyzing the image to extract a reflected image of the light source, and a step of performing a good/defective judgment of the shape of the glass sheet G based on the result of comparing data regarding to the extracted reflected image with data regarding to the reflected image by a good product which is registered in advance.

The present invention relates to a lapping oil composition which is advantageously used in finish-grinding of a material to provide a high-quality grinding surface, without selective grinding, which is generally caused during lapping and polishing processes of the composite material. The lapping oil composition contains at least one acetylene glycol compound and preferably further contains at least one at least one phosphoric ester compound.

Disclosed is a method of polishing a magnetic head slider whereby a by-processed step can be easily reduced. An air bearing surface of the magnetic head slider is polished with setting a bar that includes the magnetic head slider where a thin film magnetic head element is formed to reciprocate in a radius direction of a polishing plate, as well as rotating the polishing plate having a polishing surface. Polishing steps include a first polishing step of performing a height polish while rotating the polishing plate at a first velocity, and a second polishing step of performing a finishing polish while rotating the polishing plate at a second velocity sufficiently lower than the first velocity. The second velocity at the second polishing step is set so that an average linear velocity in the direction of the rotation of the polishing plate is equal to or lower than 0.032 m/s (preferably equal to or lower than 0.008 m/s). Consequently, the by-processed step that is generated on the air bearing surface of the magnetic head slider is reduced.

The present invention relates to a free abrasive slurry composition which is advantageously used in uniform grinding of a composite material composed of a plurality of materials each having different hardness, without causing selective grinding. The free abrasive slurry composition contains abrasive particles, an anti-abrasion agent as an anti-selective grinding agent and a dispersion medium and the anti-abrasive agent is a compound containing one or both of sulfur and phosphorus or hydroxyl group(s) in the molecular chain.
