Title: Optical pickup device
Inventor: YANAGAWA NAOHARU
IPC: G11B7/126
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide an optical pickup device which employs a front monitoring system APC(auto-power control), that is hardly affected by the fluctuation in production and environmental variations and has high reliability, and controls the output power of optical beams. SOLUTION: The light beams emitted from a semiconductor laser 20 are made incident on an orthoscopic prism 24 through a collimetor lens 21 and a grating 22. At that time, a portion of the beams is reflected by a reflection surface 24a, which is not AR coated, led to a front monitoring detector 23 and controlled by an APC circuit 31 so as to maintain the output power of the laser 20 constant. On the other hand, the light beams passed through the surface 24a, go through a reflection film 24b and irradiate an optical disk with a stable light quantity through a 1/4 wavelength plate 25, a reflection prism 26 and an objective lens 27. The reflected light beams are finally received by a detector 30.

IPC: G06T11/00
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To attain high speed plotting by successively generating pixel data along a scan line in the same way as a normal plotting processing by using an anti-aliasing technique for smoothing plotting an edge. SOLUTION: Line cross point data related with a cross point between each edge of a polygon and a scan line are generated from the vertex coordinates of a polygon to be plotted. The data include first outside cross point XLe and inside cross point XLi corresponding to the upstream side edge of the scan direction of a scan line N, second outside cross point XRe and inside cross point XRi corresponding to the downstream side edge of the scan direction of the scan line N, the increase ratio of a luminance value from the first outside cross point to inside cross point, and the decrease ratio of the luminance value from the second inside cross point to outside cross point. Each luminance value of the inside part of a polygon is calculated in the scan direction for each scan line based on the calculated line cross point data of each scan line.

Title: Method of cutting single-crystal gallium arsenide
Inventor: MATSUSHITA HIROYUKI
IPC: B28D5/02
Filed: 1992-06-19
Abstract: PURPOSE:To facilitate a flow of coolant liquid and remove defects due to cutting by masking use of warpages of a wafer caused by the crystal anisotropy of signal-crystal gallium arsenide and by cutting the monocrystal while giving relative movement for keeping the cut-in side of an inner peripheral blade cutter to be opened at all time. CONSTITUTION:At the time of cutting start, a single-crystal gallium arsenide (GaAs) ingot 2 is set so that a carbon base 5 comes to the side surface and, at the same time of cutting start, the ingot 2 made to move upward and then to rotate oppositely to the rotating direction of an inner peripheral blade cutter 1 about the central point O. By masking use of the nature in which the surface of GaAs warps to the opposite of the ingot 2, the ingot 2 is so rotationally controlled that GaAs comes to the inlet side of the inner peripherasl cutter 1, and thus cutting is effected in order that coolant liquid reaches the cutting part at all time. Thus, finally, cutting is conducted at the position where the carbon base 5 comes below the ingot 2, thereby cutting off the wafer 3.
