Abstract:
An optical pickup device includes a first laser element that emits first laser light, a second laser element that emits second laser light of which the wavelength is longer than that of the first laser light, an optical path composition element that composes the first laser light and the second laser light to one optical path, a wavelength selective element that acts on the composed first or second laser light; and an objective lens that condenses the first laser light and the second laser light on an optical disk. The magnitude of the power of the wavelength selective element as a lens with respect to the second laser light is larger than the magnitude of the power of the wavelength selective element as a lens with respect to the first laser light. Accordingly, it may be possible to reduce the optical pickup device and the optical disk apparatus in size.
Abstract:
A semiconductor device production system using a laser crystallization method is provided which can avoid forming grain boundaries in a channel formation region of a TFT, thereby preventing grain boundaries from lowering the mobility of the TFT greatly, from lowering ON current, and from increasing OFF current. Rectangular or stripe pattern depression and projection portions are formed on an insulating film. A semiconductor film is formed on the insulating film. The semiconductor film is irradiated with continuous wave laser light by running the laser light along the stripe pattern depression and projection portions of the insulating film or along the major or minor axis direction of the rectangle. Although continuous wave laser light is most preferred among laser light, it is also possible to use pulse oscillation laser light in irradiating the semiconductor film.

Abstract:
A pattern forming apparatus as exposure apparatus includes first and second movable stages for respectively supporting first and second boards placed thereon, and for transporting each board back and forth on a transport path. A pattern forming unit with DMD and laser forms a pattern on the board according to pattern data while the board moves into and out of a pattern forming region. A controller controls the pattern forming unit, and in a first period, moves a first board in a first direction on the transport path among plural boards, to form the pattern, and in a second period, moves a second board in the first direction on the transport path among the plural boards, to form the pattern. The pattern forming unit is disposed in a middle of the transport path, and is passed by the movable stages, for pattern forming selectively on the first and second boards.

A drive plate includes a disk-shaped plate portion; and a tooth-shaped portion formed at an outer peripheral end of the plate portion. The plate portion and the tooth-shaped portion are integrally shaped from a single steel plate material. The plate portion and the tooth-shaped portion include a carburized layer provided over an entire surface layer of the plate portion and the tooth-shaped portion, the carburized layer having a carbon concentration higher than that of a center portion of the plate portion and the tooth-shaped portion in a thickness direction. The carburized layer of the plate portion is higher in hardness than the center portion of the plate portion in the thickness direction. The carburized layer of the tooth-shaped portion has been subjected to a quenching process, and is further higher in hardness than the carburized layer of the plate portion.

Abstract:
To provide a liquid crystal display device having high quality display by obtaining a high aperture ratio while securing a sufficient storage capacitor (Cs), and at the same time, by dispersing a load (a pixel writing-in electric current) of a capacitor wiring in a timely manner to effectively reduce the load. A scanning line is formed on a different layer from a gate electrode and the capacitor wiring is arranged so as to be parallel with a signal line. Each pixel is connected to the individually independent capacitor wiring via a dielectric. Therefore, variations in the electric potential of the capacitor wiring caused by a writing-in electric current of a neighboring pixel can be avoided, whereby obtaining satisfactory display images.

Abstract:
A wireless communication device may receive a first signal from an external device, the first signal being a signal for establishing a wireless connection between the wireless communication device and the external device according to a specific wireless communication scheme. The wireless communication device may judge whether the first signal includes a first type of information or a second type of information. The wireless communication device may cause a display unit to display a displaying screen indicating the authentication information in a case where it is judged that the first signal includes the first type of information, and cause the display unit to display an inputting screen in which the authentication information is to be inputted in a case where it is judged that the first signal includes the second type of information.
