Transistors using nitride semiconductor layers as channels were experimentally manufactured. The nitride semiconductor layers were all formed through a sputtering method. A deposition temperature was set at less than 600° C., and a polycrystalline or amorphous InGaAlN layer was obtained. When composition expressed with a general expression InGaAlN (where x+y+z=1.0) falls within a range of 0.3≤x≤1.0 and 0≤z<0.4, a transistorexhibiting an ON/OFF ratio of 10or higher can be obtained. That is, even a polycrystalline or amorphous film exhibits electric characteristics equal to those of a single crystal. Therefore, it is possible to provide a semiconductor device in which constraints to manufacturing conditions are drastically eliminated, and which includes an InGaAlN-based nitride semiconductor layer which is inexpensive and has excellent electric characteristics as a channel.

According to one aspect, it becomes possible to easily modify a 3D object which is displayed in a virtual reality space. A method is performed by a computer configured to be communicable with a position detection device that includes a drawing surface and that, in operation, detects a position of an electronic pen on the drawing surface. The method includes rendering, in a virtual reality space, a first object that is a 3D object, rendering, near the first object, a display surface that is a 3D object, rendering, on the display surface, a 3D line that is a 3D object generated based on the position of the electronic pen on the drawing surface, wherein the position of the electronic pen is detected by the position detection device, and outputting the first object, the display surface, and the 3D line, which are the 3D objects, to a display.

A coordinate input device including a coordinate sensor and a wireless communication circuit that wirelessly transmits coordinate data, etc. to an external electronic device is realized without affecting coordinate detection by the coordinate sensor and without impeding downsizing of the coordinate input device. A shield sheet (C) is provided to cover the whole of a surface (back surface) of a sensor (B) opposite to a sensor input surface (front surface) facing an electronic pen. A controller () that controls transmission of the coordinate data detected by the sensor (B) to the external electronic device is disposed facing the sensor (B) with the shield sheet (C) disposed between the sensor and the controller, and a transmission antenna connected with the controller () is arranged outside a region covered with the shield sheet (C).

A hand-written information processing apparatus is provided by which such correction as to directly deal with a design drawn on a paper sheet or the like can be performed. The hand-written information processing apparatus includes a stylus detection sensor, a connection interface for outputting writing information corresponding to a writing operation of a stylus to an external apparatus which includes a display screen for displaying an image, and a display image processing information generation circuit for generating display image processing information for performing a given image operation process based on an operation input accepted by an operation input acceptance unit to the display image. An inputting face is configured such that a sheet member on which writing corresponding to a writing operation of a stylus can be visually formed can be placed thereon. In addition to a normal stylus, an ink stylus which can form a writing trace visually on a sheet member can be utilized. The hand-written information processing apparatus has a first mode for the normal stylus and a second mode for retaining writing information by the ink stylus into a memory.

An endless metal belt with reduced friction and increased durability comprises a pair of layered ring structures ( ) each formed by superposing a plurality of thin metal rings in layers so as to be slidable relative to each other, and a plurality of metal blocks ( ) arranged along the length of the pair of layered ring structures ( ) and supported on the pair of layered ring structures ( ) so as to be slidable relative to the pair of layered ring structures ( ), and the inner circumferences of the thin metal rings excluding the innermost thin metal ring (R ) are provided with oil retaining grooves ( ), and the inner circumference in sliding contact with saddle surfaces ( ) of the metal blocks ( ) of the innermost thin metal ring (R ) is a flat, smooth surface ( ) not provided with any oil retaining grooves and having a small surface roughness.

Detailed description of the invention

A process for assembling a belt for a continuously variable transmission, comprising the following steps: preparing standard elements, first adjusting elements and second adjusting elements respectively having a thickness of 1.5 mm, 1.6 mm and 1.4 mm; measuring an initial clearance &agr;i generated upon closely assembling only the standard elements to a metal ring assembly; if the initial clearance &agr;i<0.8 mm, using a predetermined number of the first adjusting elements, thereby making a clearance between the elements smaller than 0.1 mm; if the initial clearance &agr;i&gE;0.8 mm, using a predetermined number of the second adjusting elements, thereby making the clearance between the elements smaller than 0.1 mm. Thus, the number of the adjusting elements required for adjusting the clearance between the elements can be suppressed to seven or less.

Process for assembling belt for continuously variable transmission

A metal V-belt for transmitting power, looped between a drive pulley,and a driven pulley,, and comprising endless belt-form metal rings,and numerous metal elements supported along these metal rings, wherein the metal rings comprise a plurality of thin, endless belt-form metal ring sheets,(,) to,(n) superposed in the radial direction, and of these, the thickness of the innermost metal ring sheet,(,) is set to be less than the thickness of the other metal ring sheets,(,) to,(n). Here, the thickness of the innermost metal ring sheet is set on the basis of the ratio of the coefficient of friction between the innermost metal ring sheet and the metal element members to the coefficient of friction between the other metal ring sheets.
