摘要： A phase plate having a reduced size and a reduced weight and having accurately parted regions while it has the same function as a conventional two-parted optical rotation plate and an optical data recording/reproducing device capable of stably recording and reproducing are presented. A phase plate P1 comprising a polymer liquid crystal film 2 held between transparent substrates i, 4, wherein the polymer liquid crystal film 2 is parted spatially in the region into which an incident light enters, so that the light transmitting the phase plate assumes a different state of polarization depending on an aligning direction of the molecules of the polymer liquid crystal film 2. The phase plate is located as a two-parted optical rotation plate in an optical data recording/reproducing device.

摘要： A parameter adjusting device and a parameter adjusting method configured to adjust a great number of parameters used for a circuit design model of a semiconductor element such as a transistor within a short time. A parameter adjusting device adapts a circuit design model wherein a formula for analysis is derived based on a surface potential such as, for example, the HiSIM, as the circuit design model of a semiconductor element; defines a chromosome wherein a respective great number of parameters of the model are genes; and optimizes the parameter based on property measured data of a tested element, using a genetic algorithm. Parameter adjustment comprises a first step adjusting the parameters which determine the structure of the semiconductor element based on the property measured data of a long channel group; and a second step adjusting nonadjusted parameters based on the property measured data of various lengths of channels with reference to a result of the first step. Adjustment of the optimum parameters within a short time and with a high degree of accuracy, which was conventionally difficult, can be performed.

摘要： A parameter adjusting device configured to adjust a great number of parameters of a physical model by a genetic algorithm using multiple processing units within a short time. A parameter adjusting device comprises a processing assignment means wherein a part of a multiple processing means is assigned to search processing by a local search method, and assigns the processing of the local search to a low-performance processor. Also, the parameter adjusting device collects an interim result of the search by a genetic algorithm, and uses it for the search processing by the local search method. Through parallelization and efficiency of an adjusting processing by effectively utilizing the resource in the system, the parameter adjusting device can determine the group of the most appropriate parameters within a short time.

摘要： A multi-layer diffraction type polarizer and a liquid crystal element capable of realizing a stable high extinction ratio is provided. Further, a liquid crystal element is obtained, which can rotate the polarization direction maintaining high linearity of output light when linearly polarized light is incident. A multi-layer diffraction type polarizer is formed by laminating at least two polarizing diffraction gratings each having a birefringent material which straightly transmits incident light having a first polarization direction without functioning as a diffraction grating, and diffracts incident light having a second polarization direction perpendicular to the first polarization direction by functioning as a diffraction grating. Further, in order to realize an optical attenuator having a high extinction ratio even at low voltage, a phase plate made of an organic thin film is provided to cancel the retardation of the liquid crystal cell remaining when the voltage is applied. Further, in order to rotate the polarization direction of a linearly polarized incident light, the liquid crystal cell is provided with a λ/4 phase plate comprising an organic thin film.
