Abstract: A light emission control device includes a light emission controller which controls a light emitter and performs normal control and wake-up control, the normal control being control for causing the light emitter to emit light having a color temperature and luminance according to an instruction of a user, the wake-up control being control for causing the light emitter to emit light at increasing luminance over time to wake up the user who is sleeping. The maximum luminance of light emitted by the light emitter in the wake-up control is greater than the maximum luminance of light emitted by the light emitter in the normal control.

Abstract: A lighting apparatus includes: an illuminator including a light source which emits illumination light; a lighting controller which controls the illuminator; and a receiver which receives, from a control apparatus, a control command signal generated based on at least one of user information and environmental information in order to control the illumination light of the illuminator, wherein the control command signal received by the receiver includes one or more parameters including, as an element, at least one of a brightness of the illumination light of the illuminator, a color temperature of the illumination light of the illuminator, and control time for controlling the illumination light of the illuminator.

Abstract: An electronic appliance includes a circuit board mounted with an electronic-circuit component. The circuit board is covered with a shield, and a metallic heat-dissipating member is arranged on the electronic-circuit component. The shield is grounded on the circuit board, and arranged such that at least one of the surfaces is in the vicinity of the heat-dissipating member. The heat-dissipating member is grounded on the circuit board by a ground member, and at the periphery of the ground member, magnetic members are arranged.

Abstract: A high-frequency power divider having an input line, a pair of input-output lines, and a pair of high-impedance transmission lines diverging from the input line and interconnecting the first and second input-output lines. An isolation resistor is interposed between and connected to a pair of portions of the high-impedance transmission lines proximate the input-output lines. A capacitive component, corresponding to the capacitive component of the resistor, is provided at a diverging point at which the high-impedance transmission lines diverge from the first input-output line. The second capacitive component is defined by a capacitor or electrode surface.

Abstract: A high-frequency power synthesizing apparatus having a plurality of distributors arranged in a plurality of stages, a plurality of amplifiers which are supplied with outputs from a final stage of said power distributors and which amplify these outputs to a predetermined level, and a power synthesizing unit including initial-stage power synthesizers supplied with outputs from said amplifiers and a final-stage synthesizer which outputs power to an external load. The final-stage power distributors and the initial stage synthesizers are constituted by 0.degree.-hybrid modules. The output level of each amplifier is regulated and made constant by being compared with a predetermined level. The output levels of the amplifiers can be displayed on an external display.

Abstract: This invention relates to a push-pull transformer for use in a high frequency push-pull amplifier. This push-pull transformer has a coaxial line whose one end is connected to an input terminal, while the other end thereof is provided with an internal conductor and an outer conductor, the internal and outer conductors being grounded through stubs. A capacitor having a proper capacity is connected between the internal conductor and the outer conductor whereby the push-pull transformer can be properly actuated in a low frequency range other than the frequency used without any necessity to enlarge the size of the stubs.
