Abstract: A display device includes: an exterior base material including a high translucent section configured to allow light to penetrate, and a low translucent section having a lower light transmittance; a first coating layer which is provided on a surface of the high translucent section and has a lower light transmittance than the high translucent section; a second coating layer which is provided on the surface of the high translucent section and has a higher light transmittance than the first coating layer; and a third coating layer which is provided on a surface of the exterior base material including the first coating layer and the second coating layer and has a lower light transmittance than the second coating layer. The third coating layer is configured such that the surface formed on the first coating layers and the second coating layers is flush with the remaining surface.

Abstract: A packaging box includes a shelf portion which partitions an interior of the packaging box into an upper space and a lower space, an inner flap which is located above the shelf portion as an inner lid and which is bendable to a closed position where the inner flap faces the shelf portion while extending parallel thereto, and a hold-down piece which is disposed at a position facing the inner flap at the closed position in the shelf portion and which has a first bent portion bendable to protrude outward in a middle portion of the hold-down piece, the hold-down piece formed by cutting and raising the shelf portion to be capable of standing in a tilted state where a distal end side thereof extends toward a first side portion.

Abstract: A connector includes: a main body and a holder. The main body includes: a frame guiding a connected member in a mounting direction; a first support member being flexible toward the frame and protruding from the frame in a first outer direction; and a second support member being flexible toward the frame and protruding from the frame in a second outer direction. The holder include: first and second contact surfaces to which the first and second support members contact, respectively, when the main body has been inserted into the holder; and inclined surfaces inclined in a direction approaching the main body from both edges of each of the first and second contact surfaces. When the main body inside the holder moves in a direction orthogonal to the mounting direction, the first and second support member slide on the inclined surfaces and elastically deform in a direction approaching the frame.

Abstract: An imaging apparatus has a body portion and a grip belt. The body portion has an imaging element. The grip belt is connected to and supported on the body portion at a first connection portion on a front part of the body portion, a second connection portion on a lower rear part of the body portion, and a third connection portion on an upper rear part of the body portion, in a standard position in which a horizontal direction and a vertical direction in a pixel array of the imaging element are respectively made horizontal and vertical.

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: 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.
