摘要： An optical device includes a light source provided with a plurality of surface-emitting laser elements to emit a laser beam, a scanner to scan the laser beam emitted from the light source, and an optical system disposed in an optical path between the light source and the scanner and to guide the laser beam to the scanner. The optical system includes a first optical element to control a divergence angle of the laser beam emitted from the light source and a second optical element to concentrate the laser beam that has passed through the first optical element onto a to-be-scanned surface of the scanner.

摘要： A plurality of configurations is simultaneously formed in a material by a single laser beam having a desired distribution pattern of wavelengths. An input laser beam has an initial wavelength distribution pattern. The initial wavelength distribution pattern is adjusted or modified into a desired final wavelength distribution pattern. For example, the initial wavelength distribution pattern is a wide range of wavelengths in a single bell-curve distribution while the desired final wavelength distribution pattern has a specific number of sharp peaks each over a predetermined narrow range. The laser beam having the desired final wavelength distribution pattern is focused upon on a material. Because of the multiple peaks in the wavelength distribution, the laser beam is focused at a plurality of the focal distances. A number of structures is simultaneously formed in a material at the multiple focal points or at multiple locations/depths when the above laser beam is projected onto the material.

摘要： A remote control device in a vehicle is provided in proximity of a driver's seat such that an operation unit of the remote control device is manually rotated and pressed by a hand of a driver in a driver's seat. A case of the remote control device contains vibrators to vibrate left and right sides of the remote control device. A navigation device is connected to a control unit of the remote control device. When a position of the vehicle approaches a specified guidance point during route guidance, the navigation device outputs a guidance signal (left-turn or right-turn instruction) to the control unit. When supplied with the guidance signal, the control unit controls driving of the vibrators to vibrate the remote control device based on the guidance signal.
