Title: Wavelength-variable luminous element
Inventor: DOMOTO CHIAKI
IPC: H04B10/60
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a wavelength-variable luminous element wherein wavelength is easily changed. SOLUTION: Relating to a luminous element wherein, in a quantum well of a semiconductor element, a valence electron of an n-type semiconductor is coupled with a positive hole of a p-type semiconductor for releasing light, a coupling region of electron and positive hole is dynamically limited to such specified size as quantum size effect takes place, and by changing the size, the wavelength of the light thus released is changed. Here, on a semiconductor substrate 10, a GaAs quantum well layer 14 which is a semiconductor layer comprising a flat part 14a and a slope 14b is formed as to be an active layer, and a lateral p-n joint is formed due to difference in conduction type, between the flat part 14a and the slope 14b of the active layer.  With a wavelength control electrode 20a applied with a negative voltage, the region of electron passing the coupling region is so reduced by electric field effect as to be almost wire shape, for quantum size effect.

Title: Hatching plotting method
Inventor: FUNAHASHI HIROYUKI
IPC: G06T11/40
Filed: 1988-09-17
Abstract: PURPOSE:To shorten the calculation time required for the processing by calculating an intersection of each segment and the outside periphery of a graphic, and connecting the calculated intersections of every segment at every segment. CONSTITUTION:A two-dimensional coordinate system in which one coordinate axis coincides with the inclination angle direction of hatching which is brought to plotting is formed. Subsequently, plural segments of an equal interval which coincide with hatching on its coordinate system and parallel to one coordinate axis are set, and an intersection of each segment and the outside periphery of its graphic is calculated. Next, the calculated intersections of every segment are connected at every segment. Accordingly, at the time of calculating an intersection of the segment which coincides with hatching and the outside periphery of the graphic, the segment can be calculated as a segment being parallel to the X axis of the coordinate. As a result, by only judging whether a Y coordinate value of the segment being parallel to one coordinate axis is contained between a Y coordinate value of a start point of each segment for constituting the outside periphery and a Y coordinate value of its end point, its calculation can be executed simply.

Abstract: PURPOSE:To increase the usable frequency by connecting a reactance circuit having a prescribed inductance and whose one end is grounded via a capacitor to a gate terminal of each FET so as to increase the cut-off frequency decided by a gate-source capacitance of the FET. CONSTITUTION:An inductor 10 having a prescribed inductance is connected to a gate of each FET 3 and the other end is grounded via a DC blocking capacitor 11. Thus, the end of the inductor 10 is opened in terms of DC to short-circuit the inductor in terms of high frequencies. Since the capacitance viewed from the gate-source terminal of the FET 3 is decreased equivalently, the cut-off frequency is increased and the unable frequency is increased.

Title: Inclination adjusting device for optical member
Inventor: IKEGAME TETSUO
IPC: G02B7/00
Filed: 1987-09-21
Abstract: PURPOSE:To easily and quickly execute an inclination adjustment by forming respectively mutual slide surfaces with which an optical member is slid against its fitting block with different curvatures. CONSTITUTION:The slide surface of an optical pick-up main body 3 to receive a spherical projection 2a of an actuator 2 is a conical surface 11. That is to say, when the curvatures of the slide surfaces of the optical member and the fitting block are different, these slide surfaces are not in surface-contact but in line or point-contact. Consequently, since the clearance between the outline part of one slide surface and the other slide surface becomes large, even when a projecting part is formed on the outline part by a dent and a burr, it becomes hard to come into contact with the other slide surface. Thus, a good slide characteristic can be always obtained and the inclination adjustment of the optical member can be executed easily and quickly.
