Abstract: A BIOS saves, when a system is changed to a suspended state, contents of a VRAM included in a display controller in a VRAM save area reserved on a system memory, and then cuts off power supply to sections of the system, including the display controller, while maintaining power supply to the system memory. In the meantime, at the time of resume, the BIOS resumes the power supply to sections of the system, including the display controller, and then restores the contents saved in the VRAM save area of the system memory to the VRAM.

Abstract: A protector film is formed on the surface of a substrate to cover at least the side surface thereof. Then, a compound semiconductor film including nitrogen is grown through epitaxial growth on the substrate at an exposed portion. Then, the substrate and the compound semiconductor film are separated from each other by irradiation of laser light, polishing of the substrate, etching, cutting, etc. Consequently, the resulting compound semiconductor film is used as a free-standing wafer.

Abstract: In a laser diode module of the invention, a coupling optical system is inclined in an xz plane with respect to an optical axis (z axis) of outgoing light of a laser diode. More specifically, a coupling angle &thgr;lens of a laser diode and a lens is adjusted and fixed with a precision of 0.1° while monitoring a light output. By the operation, the coupling angle &thgr;lens is adjusted to an angle at which a light output which can be emitted without causing a kink becomes the maximum. As a result, even when the wavelength of the outgoing light is fixed by using a fiber grating, light can be emitted without causing a kink. Thus, a laser diode module capable of sufficiently increasing the maximum value of a light output can be obtained.

Developing devices are disposed corresponding to the plurality of image bearing members and develop the latent images with developers. A transfer material bearing and conveying member and a transfer device to sequentially transfer the developer images developed on the plurality of image bearing members to the transfer material on the transfer material bearing and conveying member are also a part of the image forming apparatus. The apparatus also has a cleaning member which cleans the surface of the transfer material bearing and conveying member. A developer image that is not to be transferred onto the transfer material is formed only onto one image bearing member disposed downstream in the movement direction of the transfer material bearing and conveying member among the plurality of image bearing members.
