Abstract: The present invention aims at providing a biomaterial composite not having risks of pathogen infection and unfavorable side effects such as rejection response. According to the invention, there is provided a biomaterial composite, which comprises a polypeptide and a calcium phosphate compound, said peptide comprising the units of Formulas (I) to (III): [—(OC—(CH2)m—CO)p-(Pro-Y-Gly)n-]a??(I) [—(OC—(CH2)m—CO)p-(z)r-]b??(II) [—HN—R—NH—]c??(III) wherein m, p, q, Y, n, Z, r, R, a, b and c are as defined in the specification. The composite of the invention is particularly suitable for an artificial bone due to its high biocompatibility, high endurance and mechanical strength. Further, the invention can provide a process of the composite according to the invention can for preparation of the composite having excellent mechanical characteristics by a simple procedure.

Abstract: The label printing apparatus has a structure including: a label feed means for successively feeding plural labels, each having an information printing area including a heat-sensitive color developing ink layer, to predetermined printing positions; a laser printing device which is provided with a sensor and a light source, said sensor serving to discriminate between presence and absence of the label in the predetermined printing position and to output a label detection signal, said light source serving to release a laser beam, and which receives the label detection signal directly from the sensor, prints information on the label by means of the laser beam when the presence of the label on the predetermined printing position is confirmed by the label detection signal, and outputs a shot signal; and a controller to discriminate whether the output interval between the shot signals is within a given period of time or not and to output an error signal when the output interval between the shot signals is not within
