Title: Dual mode modulator
Inventor: HOSOYA MANABU
IPC: H03C3/00
Filed: 2000-11-20
Abstract: PROBLEM TO BE SOLVED: To provide both an FM analog modulation function and a digital modulation function such as π/4 QPSK to a professional wireless device. SOLUTION: Sections after an analog/digital converter section 1 are a digital modulation means employing quadrature modulation and sections after a signal setting section 7 are a frequency modulation means employing a PLL circuit. In the case of selecting digital modulation, a setting section 15 throws a SW 1 to a position (a) and a SW 2 to a position (b) respectively. A VCO 13 outputs a non-modulation oscillation signal to the setting of the SW 2 thrown to the position (b), and the signal is used for a local oscillation signal of a quadrature modulation section 6. Thus, the digital modulation is conducted. Furthermore, in the case of selecting analog modulation, the setting section 15 throws the SW 1 to a position (b) and the SW 2 to the position (a) respectively, and sets a mapping processing section 3 to apply mapping processing of (1+j0) on the I axis.  Thus, the quadrature modulation section 6 provides no modulation and the quadrature modulation section 6 output an FM wave from the VCO 13.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a micro-spheric or aspheric polymer array structure in the form which can be accurately controlled on a substrate by an easy and convenient method and to provide a method for forming a three-dimensional pattern in a specified form by etching a polymer material.

Shocks are added to a polymer material applied on a substrate by irradiating with excimer laser light through the curved line pattern of the mask to etch the polymer to peel. During the irradiation, the substrate is moved in the direction perpendicular to the straight line direction so that the polymer material is irradiated with light for different periods at different positions along the straight line direction to produce different etching depth. Thus, the polymer material is etched to form a three-dimensional pattern of a specified form by etching. Or, the nearly spheric or aspheric micro-array structure is obtained by etching by irradiation in two different directions or through different mask patterns.
