Abstract: Provided is a stampable sheet containing (A) a thermoplastic resin, (B) a flame retardant, (C) a dispersant, and (D) an inorganic fiber, wherein the content of the (D) inorganic fiber is 1 to 80% by mass based the total weight, and based on 100 parts by mass of the (B) flame retardant, the content of the (C) dispersant is more than 0 and 25 parts by mass or less. According to the present invention, it is possible to provide a stampable sheet which is excellent in strength, rigidity and flame shielding performance, and which is also excellent in workability such as stamping molding.

Abstract: Provided is a battery housing made of a fiber-reinforced resin, containing at least an inorganic fiber having a melting temperature of higher than 1000° C. as the fiber. It is possible to provide a battery housing made of a fiber-reinforced resin capable of delaying the spread of fire to an automobile interior member when thermal runaway of a battery occurs and flame is generated, and having excellent flame shielding performance.

Abstract: A device for driving a solenoid including a power supply, a switching element connected between the power supply and the solenoid in series therewith, a current circulating diode connected in parallel to the solenoid, a current detecting circuit for detecting an actual current flowing through the solenoid, and a PID computing unit for computing an on-duty value and an off-duty value according to a difference between a target current and the actual current detected and for outputting the on-duty value and the off-duty value. The device further includes a PWM duty driving unit for generating a PWM duty signal according to inputting of the on-duty value and supplying the PWM duty signal to the switching element to on/off control the switching element, and a reverse voltage applying circuit capable of applying a voltage of the power supply as a reverse voltage to the solenoid according to inputting of the off-duty value when the switching element is off.
