摘要:
A method for producing a resin substrate coated with a titanic acid film, characterized in that it comprises providing a suspension of a scaly titanic acid by treating a layered titanate with an acid or warm water and allowing a basic compound having a force swelling the interstice of the layer to act thereon, to swell or separate the layer, applying the suspension on a resin substrate, and subjecting the resultant substrate to a heat treatment at a temperature less than the softening temperature of said resin substrate, preferably at a temperature less than 100° C., to thereby form a titanic acid film on the resin substrate. The above method can be suitably used for forming an inorganic coating film excellent in transparency, surface hardness, gas-barrier property and the like on any type of resin substrate with good adhesion property.

A charge control device for controlling charging of a secondary battery by using a current limit function of an external power supply includes: a charge control element arranged to be connected in series between the external power supply and the secondary battery; a constant current control unit configured to control an output current of the charge control element to be constant; a constant voltage control unit configured to control an output voltage of the charge control element to be constant; and an ON state setting unit configured to set the charge control element to an ON state, wherein the charge control element includes a control terminal to which a control signal for controlling the output current and the output voltage is input, and is composed of a single output element.
摘要:
In initial generation (for example, shipping from the factory), a security device generates an identifier w specific to the security device, with the PUF technology, generates key information k (k=HF(k)) from the identifier w, generates encrypted confidential information x by encrypting (x=Enc(mk, k)) confidential information mk with the key information k, and stores the encrypted confidential information x and an authentication code h (h=HF′(k)) of the key information k, in a nonvolatile memory. In operation, the security device generates the identifier w with the PUF technology, generates the key information k from the identifier w, and decrypts the encrypted confidential information x with the key information k. At a timing where the identifier w is generated in the operation, the security device checks whether the current operating environment has largely changed from the initial generation (S311). If a change in operating environment is detected (S311→S312), the security device conducts a reset-up process (S312 to S315) of an authentication code h which is confidential information, and the encrypted confidential information x.
摘要:
A charge controller includes a charge control circuit that, when detecting that a charging power supply is connected, controls the charging transistor to apply the charge current; a first and second control switch element connected in series between one terminal of a secondary battery and an external terminal; and a protection circuit that, when the secondary battery is over-discharged, turns off the first control switch element to stop discharge current and when deeply discharged, turns off the second control switch element. The protection circuit sends a charge inhibit signal to the charge control circuit when the secondary battery is deeply discharged, and while receiving the charge inhibit signal, the charge control circuit keeps the charging transistor off to prevent the charge current from flowing even if detecting that the charging power supply is connected.
