Title: Speaker
Inventor: YAMAZAKI KAZUYA
IPC: H04R3/00
Filed: 1983-07-05
Abstract: PURPOSE:To enable free setting of allowable input power value by providing a voice coil temperature detector that outputs an electric signal according to the heat, sensing heat due to temperature rise of a voice coil. CONSTITUTION:When input is applied to a speaker 14, a voice coil generates heat to raise temperature. With the rise of temperature, output voltage of a pyroelectric type infrared sensor 16, a noncontact sensor, is increased, and output amplified by an amplifier 17 is inputted to a comparator 18. This signal is compared with the level of reference signal set arbitrarily by an upper limit temperature setting circuit 19. When the signal from the amplifier 17 becomes larger than the signal from the upper limit temperature setting curcuit 19, a cut off circuit 20 operates to cut off input from an audio amplifier 13 to the speaker 14. Thus, by noncontact detection which is characteristics of the pyroelectric type infrared sensor 16, temperature of the voice coil 9 can be measured directly, and allowable input electric power value can be selected freely by setting to the upper limit temperature setting curcuit 19.

Abstract: PURPOSE:To improve especially re-startability at the time of high temperature in an air vent part of a carburetor for an internal combustion chamber by closing an air vent passage at the time of high temperatural, and by opening it at the time of low temperature, and by providing structure parts which are formed of an opening memory alloy. CONSTITUTION:At an upper side of an air vent part 3 in a carburetor 1 which has a float chamber 2, there is a flap valve 14 which is formed of an opening memory alloy. In a hot soak at the time of stoppage of an engine, according to the raise of atmospheric temperature, the flap valve 14 is deformed in the form of a memory shape so as to close the air vent part 3. Consequently, the float chamber 2 is sealed, and flowing-out of evaporation fuel into an intake pipe is prevented. When the ambient temperature is decreased after the start-up of the engine, the flap valve 14 is resumed to the initial shape, and then the float chamber 2 is connected to the intake pipe. Inside pressure and pressure of the float chamber 2 are thus made equal, and fuel injection from a nozzle 13 is performed finely.
