Abstract: A planar light-emitting device has a plurality of light-emitting units each including a light source and a lightguide plate. The light-emitting units are arranged with the light-exiting surfaces of their respective lightguide plates being substantially flush with each other. Each lightguide plate has an upper surface as a light-exiting surface, a lower surface opposite to the light-exiting surface, and a peripheral side surface extending between the respective peripheral edges of the upper and lower surfaces. The lightguide plate emits light received from the light source from the light-exiting surface. At least a part of the peripheral side surface is an inclined surface inclined relative to the light-exiting surface.

Abstract: An actuator for automobiles has a housing in which a communication channel for ventilation is formed, the communication channel allowing the inside and the outside of the housing to communicate with each other. Only one communication channel is formed, and the communication channel has an ascending portion that increases in height toward the inside of the housing. The ascending portion is formed so that a vertically lowermost point of the end (a second opening) of the ascending portion on the inner side of the housing is positioned higher than an uppermost point of the end (a first opening) of the ascending portion on the outer side of the housing. With such a configuration, condensation in the housing is minimized, and the risk of malfunction due to entrance of water is minimized.

Abstract: A multi-input amplitude and phase measuring method is disclosed for measuring the amplitudes and the phases of measurement signals at a high speed and with a high degree of reliability. Measurement signals received by antennae are converted into IF signals with local signals of frequencies f.sub.LO +.DELTA.f, f.sub.LO +2.DELTA.f, f.sub.LO +3.DELTA.f, f.sub.LO +4.DELTA.f by a mixer and then added by an adder, whereafter they are multiplied by an analog multiplier to convert phase information of the measurement signals into signals of frequencies .DELTA.f, 2.DELTA.f, 3.DELTA.f, 4.DELTA.f. Then, the signals obtained by the conversion are A/D converted and Fourier transformed to determine a spectrum. Then, in order to eliminate an influence of phase displacement by band-pass filters, the local signals are added by an adder and multiplied by a local signal of frequency f.sub.LO by a mixer, and the resultant signal is A/D converted and Fourier transformed to determine a spectrum. A cross spectrum of the two spectra is calculated by a cross spectrum calculator to measure the amplitudes and the phases of the measurement signals.
