A magnetoresistive element includes: a detection surface that receives a magnetic field to be detected; a free layer made of a ferromagnetic material, having an end face located in the detection surface, and exhibiting a change in magnetization direction in response to the magnetic field to be detected; a pinned layer made of a ferromagnetic material, disposed away from the detection surface, and having a fixed magnetization direction; and a coupling portion made of a nonmagnetic material and coupling the free layer to the pinned layer. The coupling portion includes a nonmagnetic conductive layer that allows electrons to be conducted while conserving their spins.

There is provided a very thin light guide plate for a surface light source device and a method of manufacturing it without the use of high-precision molding machine. A surface light source device using this light guide plate generates outgoing light having high uniformity. According to the manufacturing method, a light guide plate free from a weld line or warp can be manufactured with good transferring characteristics. The light guide plate is thick on an incident surface 1 side and thin on a lower surface 4 side. At the central portion of an incident surface 1 in a longitudinal direction, a projecting portion obtained by cutting an overhang portion 7 at a position a distance D apart from the incident surface 1 is formed. The cut surface of the projecting portion is not made specular and is kept rough. In molding of the light guide plate, a molten material is supplied from the position of a gate mark 9. After molding, the overhang portion 7 is cut off by an ordinary cutter, thereby obtaining a light guide plate.

An OCT probe has a sheath to be inserted into a subject; and an optical system within the sheath, for changing the direction of light which propagates from a light source through an optical fiber to irradiate the light onto the subject through a transparent portion of the sheath, and for reflecting the light beam, which is reflected by the subject, to guide the light into the optical fiber. A light output surface, for causing the light to be output from the reflecting surface in a direction obliquely inclined with respect to the inner surface of the sheath, and a reflected light sheath entrance preventing portion, for preventing light reflected by the inner surface of the sheath from entering the optical fiber, are provided in the optical system. The reflected light sheath entrance preventing portion may be formed by providing a cut planar surface portion on the lens.

In a scroll compressor, a center of a turning scroll body is shifted with respect to a drive central axis so that a distance between a gravity center and the drive central axis in a turning scroll becomes smaller than a predetermined allowable value set based on theoretical displacement and mass of the turning scroll. A moment force about the drive central axis acting on the turning scroll is reduced during revolving, and an alternating force acting on an autorotation preventing pin in the turning scroll is reduced to an allowable level.

An editing device selects, among the video of the video data, a scene such as a backlit scene and a camera shake scene which has a characteristic different from a necessary scene, as an unnecessary scene, and reproduces the selected unnecessary scene on a display unit. Accordingly, the editing device allows the user to select necessary scenes and unnecessary scene from among the camera shake scenes or the backlit scenes. In addition, for example, if a camera shake scene is present in similar videos that are captured at substantially identical locations, the user can recognize that the camera scene is present without conducting an operation to select the camera shake scene.

The present invention provides an electronic device with improved characteristics and a method of making the electronic device. In a method of making an electronic device (piezoelectric device) 74 according to the present invention, an outer edge R1 of a piezoelectric film 52A formed on an electrode film 46A of a laminate 60 is located inside an outer edge R2 of the electrode film 46A. For this reason, in removal of a monocrystalline Si substrate 14 from a multilayer board 61, where an etching solution permeates between polyimide 72 and laminate 60, the etching solution circumvents the electrode film 46A before it reaches the piezoelectric film 52A. Namely, a route A of the etching solution to the piezoelectric film 52A is significantly extended by the electrode film 46A. In the method of making the electronic device 74, therefore, the etching solution is less likely to reach the piezoelectric film 52A. It significantly suppresses a situation of dissolution of the piezoelectric film 52A and realizes improvement in characteristics of the piezoelectric device 74 made.

A surface light source device of side light type illuminating an LCD panel and comprising a guide plate, a primary light source, a reflection sheet, and a prism sheet for light control. A plurality of fine light scattering elements and rough area M are formed on an emission face of the guide plate. The rough area M is formed among the light scattering elements and has scattering power weaker than that of the light scattering elements. The dot-like light scattering elements are distributed according to a certain pattern that is designed to promote emission. Emission is promoted where the light scattering elements are formed and also in the area M. Accordingly, fine periodic bright-dark unevenness and glaring are reduced and the prism sheet, disposed on the emission face, is prevented from sticking to the emission face.
