A circuit startup method utilizing utterance estimation in a speech processing system including a sound collecting device is provided. The circuit startup method includes a subset power supply step of supplying power to the sound collecting device and a signal processing circuit, and a sound collecting step of inputting a sound from the sound collecting device through the signal processing circuit. The circuit startup method further includes an utterance estimation step of estimating whether or not a speech is contained in the inputted sound, and a power supply step of supplying power to the speech processing circuit for an utterance interval when it is estimated that a speech is contained from an estimation result of the utterance estimation step.

A lighting remote control system includes an illuminating device for irradiating illumination light in a changeable direction, a remote controller for irradiating visible light, a direction sensor for detecting an irradiating direction of the visible light based on a posture of the remote controller, and a position sensor for detecting position coordinates of the remote controller. The illuminating device is designed to irradiate the illumination light on a position specified pursuant to the position coordinates of the remote controller detected by the position sensor, the irradiating direction of the visible light detected by the direction sensor and an arbitrarily-set unit length.

An air conditioning and ventilation system for a motorcar has an outdoor air passage for introducing fresh outdoor air into the passenger room and another passage for guiding room air to the atmosphere. The two passages intersect at a point where a heat exchanger is provided for exchanging both of the actual heat and the latent heat of the airs flowing through the two passages. Air heating and cooling units are provided in the outdoor air passage downstream of the heat exchanger. The outdoor air flows first through the heat exchanger in heat exchanging relationship with the room air flowing therethrough outwardly and thus is heated or cooled by the room air, whereby the thermal load on the air heating and cooling units is greatly reduced.

In a lighting system capable of varying luminance of the light emitting surface periodically used for adjusting rhythm of breathing of an observer when he wishes to fall asleep, a light source is controlled in a manner so that variation of the luminance “L” per a unit time in the vicinity at a time tMAX when the luminance “L” takes the largest value in one period becomes larger than the variation of the luminance “L” per the unit time in the vicinity at a time tMIN when the luminance “L” takes the smallest value.
摘要:
An air cleaner using an ionic wind having discharge electrodes, a counter electrode arranged downstream of the discharge electrodes, and first and second parallel plate electrodes arranged alternately downstream of the counter electrode. The second parallel plate electrodes are connected to a potential pick-up electrode arranged in the vicinity of the discharge electrodes. The first and second parallel plate electrodes which are arranged alternately serve as dust collecting electrodes.

A ventilating device for an automotive vehicle mounted in a rear portion of the vehicle comprises an atmospheric air passageway for introducing atmospheric air from the outside of the vehicle into a vehicle compartment, and an internal air passageway provided in a manner to cross the atmospheric air passageway for leading the air in the rear portion of the vehicle compartment to the outside of the vehicle. The atmospheric air passageway is arranged to cause the atmospheric air to be blown from the rear to the front of the vehicle compartment, so as to improve ventilation performance in the rear portion of the compartment. Further, a total heat exchanger is mounted at the crossing portion of the two passageways for effecting exchange of both sensible heat and latent heat between the atmospheric air flowing through the atmospheric air passageway and the air flowing through the internal air passageway.

A fuel evaporative emission control apparatus comprising a vessel having an adsorbent layer therein for adsorbing a vaporized fuel, and a vaporized fuel inlet conduit inserted in the adsorbent layer, wherein the improvement comprises a flow deflector of a hollow conical shape having a diameter gradually increasing upward, the deflector being embedded in the adsorbent layer, the vertical angle (.alpha.) of the flow deflector is adjusted to 60.degree. to 120.degree., the ratio (S1/S2) of the sectional area (S1) of the largest-diameter end portion of the flow deflector to the sectional area (S2) of the adsorbent layer is adjusted to 0.4 to 0.6, the ratio (a/b) of the distance (a) between the largest-diameter end portion of the flow deflector and the top end of the adsorbent layer to the distance (b) between the largest-diameter end portion of the flow deflector and the side end of the adsorbent layer is adjusted to at least 1.5, and the distance (a) is made smaller than the sum (g+b) of said distance (b) and the axial length (g) of the conduit in the adsorbent layer.
摘要:
A windshield wiper for an automotive vehicle has a flat plate located in an inclined position in which an edge of the flat plate that is upstream with respect to the air flow above the surface of the windshield is disposed closer to the surface of the windshield than the downstream edge. The flat plate also has a plurality of deflectors for disturbing the air flow. One of the deflectors is located at the upstream edge of the flat plate on the side facing the windshield and the other deflector is located at the downstream edge of the flat plate on the side opposite the windshield.
