Abstract: It is made possible to perform data transmission through a cable satisfactorily. A cable is connected between first electronic equipment and second electronic equipment. The cable includes a current consumption unit that receives supply of current from the first electronic equipment through a power supply line, a current monitor unit that observes a current amount the first electronic equipment is capable of supplying to the power supply line, and an information transmission unit that transmits control information according to the observed current amount to the first electronic equipment. The first electronic equipment controls the state of data to be supplied to the cable, on the basis of the control information transmitted thereto from the cable.

Abstract: To mitigate the accuracy of misalignment to reduce costs, and to suppress an inter-mode propagation delay difference to enable high-quality transmission of signals. An optical waveguide is configured to propagate only a fundamental mode at a first wavelength and propagate at least a first-order mode as well as the fundamental mode at a second wavelength. The optical waveguide is configured such that a refractive index distribution of a core and a cladding is controlled so that the inter-mode propagation delay difference is within a predetermined threshold, for example, the inter-mode propagation delay difference is zero, when communication is performed using light of the second wavelength. For example, the first wavelength is in a 1310-nm band and the second wavelength is in an 850-nm band.

Abstract: A push-button switch may include a housing, an operation unit, a lock lever unit, a transmission mechanism, a movement regulating portion, a contact mechanism, and a first biasing portion. The movement regulating portion enables movement of a lever body to a second position when an end of the operation unit on a housing portion side is positioned at an initial position, and disables movement of the lever body to the second position when the end of the operation unit on the housing portion side is positioned closer to an operation surface than the initial position in a movable direction. The first biasing portion biases the plunger from an operating position toward a return position.

Abstract: A push button switch may include a housing, an operation unit, and, a lock lever unit. A lever body of the lock lever unit may have a locking portion capable of locking one end of a long jig in an extending direction. The housing may have a fulcrum projection that contacts an intermediate portion of the jig having the one end locked to a locking portion when the lever body is moved using the jig, and serves as a rotation fulcrum of the jig.

Abstract: A push-button switch may include a housing, a plunger, an operation unit, a transmission mechanism, a contact mechanism, and a biasing portion. The plunger may have a first plunger that is disposed in series with the first plunger. The first plunger and the second plunger may be movable independently of each other. The contact mechanism may be configured to be opened/closed by movement of the second plunger.

Abstract: A push-button switch may include a housing, an operation unit, a lock lever unit, and a biasing portion. A lever support portion may be connected to the operation unit so as to be movable together with the operation unit when a lever body is positioned at a second position. The housing may have a deformation portion that, when the operation unit is pulled in an opening direction when the lever body is positioned at the second position, deforms the lever body so as to be capable of releasing the pressing to the lever body by a holding unit.

Abstract: A switch device includes an actuation unit, a movable unit, a first base, and a second spring, which is a torsion coil spring that acts between the actuation unit and the movable unit. The movable unit is movable with respect to the base. The second spring applies a force to the actuation unit when the actuation unit is at a third position in a direction that is not parallel to a direction in which the torsion coil spring applies a force to the actuation unit when the actuation unit is at a fourth position.

Abstract: A pressure-sensitive adhesive composition including an addition reaction type silicone polymer as a component (A); an ultraviolet absorber as a component (B); and a platinum group metal catalyst as a component (C). The ultraviolet absorber as the component (B) includes a benzophenone-based ultraviolet absorber and its amount is set to a value within the range of 1 part to 4 parts by weight relative to 100 parts by weight of the addition reaction type silicone polymer as the component (A). The amount of the platinum group metal catalyst as the component (C) is set to a value within the range of 0.001 parts to 0.05 parts by weight relative to 100 parts by weight of the addition reaction type silicone polymer as the component (A).

Abstract: Provided is a switch that can be downsized. A switch is provided with a plunger, two upper torsion springs that bias the plunger in a returning direction, housing-side contacts, and plunger-side contacts. One of the upper torsion springs is arranged on one side of a plane that includes an axis passing through a central portion of the plunger, and that is perpendicular to perpendicular lines M connecting the plunger-side contacts and the axis, and the other one of the upper torsion springs is arranged on the other side of the plane.
