Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent duplication completely even when a copy machine having high resolution and color correcting function is used by producing a printed matter where arbitrary image information is concealed only when it is passed through a color copy machine by the optical effect of a double print image layer regardless of the pattern, line width, or the like. SOLUTION: When an anti-duplication printed matter 7 is copied by a commercially available color printer, an image forming a second print image part 4 constituting a part of the face image of a person in an original printed matter is affected by a yellow based ink printed on an underlying print image layer 2 even if the density is regulated using a color correcting function to produce a yellowish print. Furthermore, color difference from a third print image part 5 is conspicuous and the color is equalized to that of a first print image part 6, i.e., the background, resulting in a copy 8 where only a part of the face image of a person forming the third print image part 5 can be recognized visually. In other words, a mark X formed in second print image part 4 is recognized in the face image of a person.

Title: Aqueous food
Inventor: OKIYAMA ATSUSHI
IPC: A23L29/00
Filed: 1985-10-07
Abstract: PURPOSE:To improve the taste of an aqueous food and to stabilize a suspension of particles such as fruit juice pulp, by compounding an aqueous food with a stabilizer consisting of decomposed cellulose produced by acetobacter. CONSTITUTION:An aqueous food added with decomposed cellulose produced by acetobacter. The amount of the decomposed cellulose is generally 0.05-1.5% based on the aqueous food. When the amount is less than 0.05%, the suspension- stabilizing effect becomes poor and when it exceeds 1.5%, the produced food has poor palatability. The suspension-stabilizing effect of the decomposed cellulose to the aqueous food is caused by the formation of network structure with microfibers of cellulose produced by acetobacter and the suspension of the network structure in the aqueous food. The structure is effective to prevent the precipitation of fruit juice pulp in the case of fruit juice drink, the precipitation of cocoa particles in the case of cocoa milk drink or the coagulation of emulsified flavor in the case of emulsified flavor.

IPC: H05K7/08
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a new reduced-weight enclosure structure for portable device the rigidity of which can be improved by incorporating a relatively light material in the enclosure while the wall thickness and weight of the enclosure are reduced. SOLUTION: In a reduced-weight enclosure, a plurality of columnar spacers 6 is provided between an upper case 1 and a lower case 4 in such a state that the spacers 6 are brought into contact with the cases 1 and 4. It is preferable to use a 30-time foamed styrene for forming the spacers 6, because the styrol has such elasticity that is suitable for protecting and absorbing the deformation of the cases 1 and 4 in addition to a specific gravity which is lower than those of resins and an excellent restoring property. When external forces are applied to the cases 1 and 2, the spacers 6 prevent the breakage or large deformation of the enclosure by reducing the deformation of the cases 1 and 2.
