摘要： 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.

摘要： A camcorder has a main body, a lens, which is provided on a front surface portion of the main body, and a display unit having a display screen, which displays incoming images from the lens. A first surface of a rear surface portion of the main body faces the display unit and is concave toward the front surface portion of the main body. A second surface of the display unit faces the first surface. The second surface is convex toward the front surface portion of the main body corresponding to the first surface. The first surface slidably moves the display unit with respect to the second surface.
