A printing apparatus management system includes: a printing apparatus which includes an IC tag performing wireless communication with the outside and a memory being connected to the IC tag; and a first information terminal which has at least a function of writing information in the memory through wireless communication with the IC tag. The first information terminal maintains authentication data used by the printing apparatus, writes the authentication data in the memory, and transmits the authentication data to another information terminal. In addition, the printing apparatus interrupts a predetermined function, when the authentication data is written by the first information terminal, and in a state where authentication data is written in the memory by the first information terminal or an information terminal other than the first information terminal in the interruption state, the printing apparatus makes the predetermined function effective, when the authentication data written by the first information terminal before the interruption state and the authentication data written by the first information terminal or the information terminal other than the first information terminal after the interruption state accord with each other.

Provided is a cutting method for a glass sheet, comprising radiating a laser beam to a cutting portion (C) of a glass sheet (G) having a thickness of 500 μm or less to fuse the glass sheet (G), wherein a narrowest gap between fused end surfaces (Ga1 and Gb1) of the glass sheet (G), which face each other in the cutting portion (C), is managed to satisfy a relationship of 0.1≦b / a≦2, where “a” is a thickness of the glass sheet (G) and “b” is the narrowest gap.

To make the strict management of the security information possible, in a security information packaging system 120 which comprises a storing portion 120a for storing first encrypted security information EDK(MK) / address obtained by encrypting final security information DK by using internal security information MK and second encrypted security information EMK(CK) / address obtained by encrypting the internal security information MK by using converted security information CK, and an LSI 120b, the LSI 120b includes a seed generating portion 131 for storing a first constant IDfuse / address containing address information and serving as a generation source of a conversion seed and a second constant IDtst serving as a generation source of a conversion seed for testing and a third constant Const and then outputting either the conversion seed or the conversion seed for testing in response to a test signal.

A security information implementation system includes a storage section 120a for storing first encrypted security information EDK (MK) provided by encrypting final security information DK according to internal security information MK and second encrypted security information EMK (CK) provided by encrypting the internal security information MK according to conversion security information CK and an LSI 120b including a seed generation section 131 for storing a first constant value containing address information on which a conversion seed is generated based and a second constant value and a third constant value on which a test conversion seed is generated based and outputting the first constant value and the second constant value or the third constant value as the conversion seed or the test conversion seed in response to a test signal and a mode setup value; a one-way function circuit 32 for converting the conversion seed or the test conversion seed output from the seed generation section 131 according to the first encrypted security information EDK (MK) input from the storage section 120a to generate the conversion security information CK or test conversion security information; a decryption circuit 33 for decrypting the second encrypted security information EMK (CK) input from the storage section 120a using the output of the one-way function circuit 32 as a key; and a decryption circuit 34 for decrypting the first encrypted security information EDK (MK) input from the storage section 120a using the output of the decryption circuit 33 as a key.

A thick film green sheet slurry, a production method of thick film green sheet slurry, a production method of a thick film green sheet, a thick film green sheet and a production method of an electronic device are provided; by which coating of a relatively thick film becomes possible, a sheet formed after coating has excellent cutting property (strength capable of being cut), and a sheet having high air permeability, excellent handleability and a high adhesive force can be formed. In the present invention, a thick film green sheet slurry comprises a ceramic powder, a binder resin including a butyral based resin as the main component, and a solvent: wherein the solvent includes a good solvent for letting the binder resin dissolved well therein and a poor solvent having lower solubility to the binder resin comparing with that of the good solvent; and the poor solvent is included in a range of 30 to 60 wt % with respect to the entire solvent. The good solvent is alcohol, and the poor solvent may be toluene, xylene, mineral spirit, benzyl acetate, solvent naphtha, etc.
