An anti-reflection film comprises a low refractive index layer provided on one surface of a transparent support. The low refractive index layer has a refractive index of not higher than 1.45. The low refractive index layer has a surface average reflectance of not higher than 1% within the visible region of 400 to 800 nm. According to the first embodiment of the present invention, an infrared absorbing layer is provided between the transparent support and the low refractive index layer. According to the second embodiment of the present invention, an infrared absorbing layer is provided on the other surface of the transparent support. The infrared absorbing layer contains an infrared absorbing dye. The infrared absorbing layer decreases a transmittance of the film to not higher than 40% at a wavelength within the infrared region of 800 to 1,100 nm. Plasma display panels using the anti-reflection films are also disclosed.

An electronic apparatus has a normal mode and an energy saving mode for reducing power consumption, and includes a main control unit, a sub control unit, a main storage unit, and a sub storage unit. The sub control unit includes a processing unit performing a part of an update process by storing software update data in the sub storage unit when a software update request is received during the energy saving mode. The main control unit includes a processing unit performing a rest of the update process by moving or copying the software update data from the sub storage unit to the main storage unit and by updating software stored in the main storage unit with the software update data after the electronic apparatus returns from the energy saving mode to the normal mode.

摘要:
For grinding one of axially spaced journal sections of a workpiece each having a cylindrical surface and a pair of shoulder surfaces extending radially outward from the opposite end portions of the cylindrical surface, a rotating grinding wheel is advanced to grind the shoulder surfaces of one journal section and then to grind the cylindrical surface of the one journal section. At the end of the cylindrical surface grinding, the grinding wheel is retracted by a fixed distance at a slow feed rate and is further retracted at a rapid feed rate. A rest shoe provided on the side opposite to the grinding wheel with the workpiece therebetween is advanced to an advanced position where the rest shoe contacts with another journal section axially spaced from the one journal section to decrease the flection of the workpiece caused by grinding resistance and is retracted away from said another journal section when the fixed-distance retraction of the grinding wheel is completed.
