Abstract: PURPOSE:To facilitate the introduction of a session key at a terminal by providing a means for generating a key intrinsic to the terminal to a master station, providing a means for generating a session key common to the master station and the terminal to relieve the load of the key management by the master station. CONSTITUTION:A converting means (f) provided in a center as a master station converts an identification number ID of an IC card as a terminal to generate a key KID intrinsic to the terminal. Moreover, a conversion means (g) provided in common to the center and the IC card generates a session key Ks used for each communication by inputting a random number from a random number generator and the key KID. Thus, in case of communication by a center to a specific IC card, the key KID is introduced via the means (f) from the ID number, the key KID and the random number R are inputted to the means (g) to obtain the key Ks. Moreover, the key Ks is obtained by similar procedures for the IC card via the means (g). Thus, the load of the key management of the center is relieved and the introduction of the session key Ks in the IC card is attained without complicated arithmetic operation.

The intensity of the magnetic force line A' of this subcarrier peak is set to <=1/2 of the intensity of the maximum magnetic force line. Therefore, the interval between the control magnetic pole and the maximum magnetic force line A of the conveyance magnetic pole is increased and the conveying force by the maximum magnetic force line A is decreases; and conveying force required for the subcarrier peak is secured up to the control magnetic pole and easily controlled. Consequently, the flowability of a developer is made proper and the holding force of the developer is obtained sufficiently on the external surface of a developer carrier.

Title: Clarifier for transparent soap
Inventor: HIGUCHI HISAO
IPC: C11D9/38
Filed: 1987-08-28
Abstract: PURPOSE:To provide the title clarifier which makes it possible to manufacture a transparent soap having excellent hue and transparency according to not only the frame process but also the milling process, and which comprises a modified rosin. CONSTITUTION:A clarifier for a transparent soap comprising a modified soap. Heretofore, a rosin has been known as a clarifier which is relatively effective in both of the frame process and the milling process. However, the use of a rosin has a problem that the transparent soap has a brown hue due to the hue of the rosin per se so that the types of usable dyes are limited. By contrast, the use of a modified rosin (e.g., disproportionation product, hydrogenation product or alcohol esterification product of a rosin) makes it possible to markedly improve the hue, and hence to obtain a transparent soap product having excellent hue and transparency. Esp., by using a variety of dyes, it is possible to obtain a beautiful, colorful product.
