Abstract: A plurality of thermoplastic articles are superimposed against a support, an infrared transparent solid is superimposed to form a superimposed body and infrared is irradiated to the superimposed body from the side of the infrared transparent solid. For the irradiation source, an Er: YAG laser or fiber laser is used. The interface temperature of the thermoplastic article becomes relatively lower and a high temperature region can be developed within the superimposed body due to the infiltration of laser energy. As a result, degradation of the surface configuration due to thermal damages in the infrared irradiation side surface layer of the thermoplastic articles can be suppressed.

Abstract: The present invention provides a novel measurement method for system parameters of a 5-port junction used in a VNA (Vector Network Analyzer). A VNA is a device for measuring amplitude ratios and phase differences (S-parameters: scattering matrix elements) between incident waves and reflected waves of a DUT (Device Under Test), or between input waves and transmitted waves. What has been newly discovered is that for 5 ports, S-parameters can be expressed by a linear coupling using H and power difference ratios ({P(S)/P(0)}?1). It is possible to easily calculate parameter H using a minimum of three already known standards, and amount of calculation can be reduced compared to conventionally.

Abstract: The present invention relates to a compound having a structure analogous to firefly luciferin. In particular, the invention relates to a heterocycle compound which produces a luminescence at a light wavelength different from that of firefly luciferin in nature. The present invention provides a heterocycle compound of following general formula I. In the above general formula, R1, R2 and R3 can be each independently H or C1-4-alkyl. In the above general formula, X and Y can be each independently C, N, S or O. In the above general formula, the olefin chain part expressed as “n” can be changed to desired length.

Abstract: A diamond thin film coating method is provided that enables, with no need for an intermediate layer, the formation of a diamond thin film, which has conventionally been considered difficult because cobalt contained in a binding phase of a cemented carbide provides a catalysis for the formation of graphite. Cobalt in a binding phase (11) present in a surface of a cemented carbide substrate member comprised of a hard phase of a carbide (2) and a binding phase (1) containing cobalt, is silicidated into silicide (3), and thereafter the diamond thin film is formed.

Abstract: There is provided a bandpass filter for a differential signal applicable to a device having a wide passband, being a device for transmitting a signal using a differential signal. Respective lines 1 and 2 and lines 3 and 4 are provide on two surfaces P1 and P2 at an inner layer of a dielectric body 9. Each two lines are arranged symmetrically about the same plane of symmetry C, and the length of each line is a quarter wavelength at the center frequency of a used band. Reference numerals 5 and 6 are input/output ends of the lines 1 and 2, and 7 and 8 are input output ends of lines 3 and 4. Opposite ends to the input output ends are open. If a differential signal is input to terminals 5, 6, a differential output appears at the terminals 7, 8. This device works as a bandpass filter.

Abstract: This invention provides an image generating method that simplifies moving body operation. This method includes the following steps. (1) a step of receiving environment information (for example, environment images) using one or a plurality of space measurement sensors (for example, a camera) attached to a moving body; (2) a step of receiving time when the environment information is received, and parameter of the space measurement sensor itself (for example, position and attitude of a camera) at the time; (3) a step of saving history information representing the environment information, the time, and the parameters; (4) a step of receiving designation for virtual observation point; and (5) a step of generating virtual environment image seen from the virtual observation point based on the saved history information.
