Patent JP-H0730447-A (JP)
Title: Radio receiver
Inventor: SATO SHIRO
IPC: H04B1/10
Filed: 1993-07-06
Abstract: PURPOSE:To simplify circuit constitution for muting and to attain stable muting control. CONSTITUTION:An IF signal is fetched from the post stage of an amplifier 14a in an IF amplification part 14 and rectified and detected by a level detection part 21 to generate a DC signal I proportional to the level of the IF signal. The DC signal is sent to a muting control part 23. The control part 23 operates so as to turn on a muting switch 24 when the DC signal I is lower than a prescribed level, so that an audio output is short-circuit by earth and interrupted. Since the level of a noise component is low when the whole signal level in an IF band is high or the noise level is high when the signal level is low, muting is controlled by utilizing the above characteristics.

The chitosane porous beads are otherwise subjected to a crosslinking treatment by using a dicarboxylic acid, dialdehyde, etc., to obtain the acid resistant chitosane porous beads. An alkane dicarboxylic anhydride is acted on the amino group contained in these porous beads to convert the same to an active supporting group having a carboxyl group. A monocarboxylic anhydride or halogenated acyl is acted on the remaining amino group to acylate the same.

Abstract: PURPOSE:To simplify the structure of a fragrance device for a compartment and to adjust the scattering quantity of a fragrant agent according to the blowing out quantity of air by providing a negative pressure generating means requiring no power as a fragrant agent scattering means, and forming the negative pressure generating means of a tubular body which protrudes inside a duct and bends its end toward the downstream of an air flow CONSTITUTION:An air flow from the blower fan 1 of an air conditioner goes toward a blow out hole 2 through art evaporator 11 and a heater core 12 which are provided in an air flow passage. A tubular body 13 is protruded inside a duct 3 just before the blow out hole 2. The tubular body 13 turns its end toward the downstream of an air flow, and a fragrant agent container 7 is attached to the other end of the tubular body 13. Thus, the blower fan 1 makes the air flow inside the duct 3 generate negative pressure in the end part of the tubular body 13. The fragrant agent is drawn out by pressure difference DELTAp between the negative pressure and atmospheric pressure and emitted into the duct 3. A power source is therefore unnecessary for the atomization of the fragrant agent, and the optimum atomized quantity can be obtained by the pressure difference DELTAp according to the speed of an air flow.
