摘要:
There is provided a thermoplastic resin composition which comprises a modified rubber having excellent low-temperature durability dispersed in a polyamide resin matrix in order to improve the low-temperature durability or repeated fatigue resistance of the polyamide resin and which maintains its flowability and can be formed into a film even at a high content of the modified rubber, and has excellent low-temperature durability. The thermoplastic resin composition comprises a modified polyamide resin (A) obtained by melt blending 100 parts by weight of a polyamide resin (A1) and 0.05 to 5 parts by weight of a compound (A2) capable of binding to a terminal amino group of the polyamide resin, at a temperature equal to or higher than the melting point of the polyamide resin (A1), and a modified rubber (B) having an acid anhydride group, an epoxy group, or a carboxyl group or a derivative thereof. The compound (A2) is preferably a monofunctional epoxy compound. The film of the thermoplastic resin composition is suitably used for the manufacture of tires and hoses.

摘要:
In a filament power supply circuit of a vacuum fluorescent display, an integration circuit is connected to a signal input terminal which receives a pulse signal having a magnitude corresponding to a DC power supply voltage. A comparison circuit compares an output voltage from the integration circuit with a reference voltage, and outputs a result. A first filament cathode connection terminal is connected to one terminal of the filament cathode of a vacuum fluorescent display and applies the DC power supply voltage to the one terminal. A second filament cathode connection terminal is connected to the other terminal of the filament cathode to ground the other terminal via a capacitive element. A three-terminal element includes first, second, and third terminals. The first terminal is connected to the first filament cathode connection terminal. The second terminal is grounded. The third terminal receives the output from the comparison circuit so that the path between the first terminal and the second terminal is switched in accordance with it.
