Abstract: A photobase generator includes a compound including a first skeleton represented by the following formula (a), and a second skeleton including a nitrogen atom bonding to a bonding position of the first skeleton to form an amide group, wherein the compound generates a base, in which a hydrogen atom is bonding with the nitrogen atom of the second skeleton, by light irradiation, and the pKa of a conjugate acid of the base in water is 12 or more. In formula (a), G is a divalent aromatic group, and * represents the bonding position with the nitrogen atom.

Abstract: An encrypted data processing system is provided including an encryption device and a server. The encryption device includes an encrypting section that encrypts first information based on a first encryption key and transmits the encrypted information for registration to the server, and encrypts second information based on a second encryption key and transmits the encrypted information to be compared to the server. The server includes a comparison section that employs a cipher comparison function for comparing encrypted information to compare the encrypted information for registration against the encrypted information to be compared, and transmits a comparison result to the encryption device. The encryption device further includes a comparison result decrypting section that employs a decryption function for decrypting the comparison result with the first encryption key and the second encryption key to find a degree of matching between the first information and the second information.

Abstract: An electret includes an electret layer. The electret layer is formed by subjecting a composite film in which inorganic dielectric particles are dispersed and held in a base film to a polarization treatment. The inorganic dielectric particles are mainly composed of an inorganic dielectric material having a bandgap energy of 4 eV or more.

Abstract: In a control device for a switched reluctance motor, a voltage drop control is executed in which a voltage dropped to be lower than a voltage applied in a case where the switched reluctance motor is driven in a high-load region is applied to the switched reluctance motor, in a case where the switched reluctance motor is driven in a low-load region. The low-load region is a lower load region than the high-load region.
