Abstract: PROBLEM TO BE SOLVED: To rapidly supply heat from a heater to a heat-accumulating body and from the heat-accumulating body to a base and reduce decrease of temperature resulting from pressing clothes and improve the usability, by fixing a heat- accumulating body made of iron to the heater and burying it in the base, in the iron body. SOLUTION: When an iron body 28 is put on a placing seat 29 of a stand 27, electric currents are conducted to a heater 21 through the electrodes 30 of the stand 27, an electric supply pin 26 of the iron body 28, and a temperature control means. The heater 21 is heated by the currents and the heat heats the aluminum base 23 and simultaneously heats the heat-accumulating body 22. When the temperature of the base 23 reaches a preset temperature and a usable state, the iron body is removed from the stand 27 to press clothes by the iron. Then the temperature of the base decreases but the heat accumulated in the heat-accumulating body 22 is dissipated to the aluminum material constituting the base 23 to reduce the temperature decrease and keep the surface temperature at a constant temperature. Accordingly, the iron can be retained in a preset temperature for a long time.

Abstract: PURPOSE:To obtain a diaphragm of a large specific elastic modulus having suitable internal loss, whose high-frequency characteristic of compass is excellent, by using a cloth of a specific aromatic polyamide fiber for the base of the surface material of a speaker diaphragm having three-layer sandwich constitution. CONSTITUTION:The surface material made of thin film of fiber reinforced plastic is adhered on both surfaces of a core member made of core material and thus the speaker diaphragm of three-layer sandwich constitution is produced, and for the base of the surface material, a cloth of an aromatic polyamide fiber plated with zinc is used. The preferable thickness of said plating is 0.05-0.5mum. Said plating is executed on single piece of the aromatic polyamide fiber or on the roving at the state of keeping the clearance of single fiber, and the plating layer should preferably be formed uniform on the whole surface of the single fiber. Thus the diaphragm has the large specific elastic modulus, hence it propagates the vibration of a voice coil bobbin faithfully when it is used being connected with the voice coil, also, since it has a suitable internal loss, a reflecting vibration from the edge is absorbed, hence the deviation in the high-frequency characteristic of compass is minimized.
