Title: Method for laminating photosensitive lithographic printing plate
Inventor: MIZUKAMI JUNJI
IPC: B41N3/00
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To stack and store photosensitive lithographic printing plates without damaging a surface of a photosensitive layer by stacking the plates for laser exposure on at least a surface brought into contact with the photosensitive layer via a sheet in which a resin layer or a resin mixture layer exists. SOLUTION: The photosensitive lithographic printing plate for laser exposure is stacked on a surface brought into contact with at least a photosensitive layer via a sheet in which a resin layer or a resin mixture layer exists. As the sheet, at least one surface may be made of the resin layer or the resin mixture layer, and a laminate sheet having the resin layer formed on a sheet surface is preferable in a practical use. As the resin used for the surface brought into contact with the photosensitive layer of the sheet, any resin can be used. For example, a thermoplastic resin such as polyethylene can be used and the resin having a melting point of 50 to 240 deg.C is desirable. As a dye for absorbing a laser beam of the photosensitive layer, a positive type photosensitive lithographic printing plate containing photothermal conversion substance and polymer binder can be advantageously used.

Title: Access controlling system
Inventor: TAGUCHI AISAKU
IPC: G11B5/55
Filed: 1988-08-25
Abstract: PURPOSE:To enable the coarse access with high roughness and the control at real time by utilizing a relationship between physical positioning information and speed information of a recording and reproducing means and making a closed loop by using a speed detecting means and a comparing means. CONSTITUTION:A distance for coarse access is calculated by a control part 209. This calculated value is compared with a prescribed value to discriminate whether the access distance is long-range or short-range. In the case of the long-range, as a result of this discrimination, a 1st reference speed is read out of a reference speed table (1st and 2nd speeds) 205, and in the case of the short-range, as a result of the discrimination, a 2nd reference speed is read out. When the coarse access is started up, a counting means 204 is commenced to count an output of a scale 203. An output of the means 204 is inputted to the table 205 to obtain a reference speed corresponding to the moving distance out of the table 205. An output of the table 205 is compared 207 with an output of a speed detecting means 202, and their difference signal is outputted to a driver 208, to drive a linear motor 201. Speed information of the motor 201 is fed back by the means 202, so that the speed control is carried out by this closed loop.

Inventor: SUMIO YUKIYASU
IPC: H04L9/06
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To improve the safety in hiding data while conducting data communication and accumulation by updating the bit string (an intermediate key), which controls a ciphering conversion, every time a ciphering is conducted. SOLUTION: Conversion means 111 to 115 have the functions to conduct linear or nonlinear bit string conversions. The functions are controlled by the intermediate keys held in intermediate key storing means 131 to 135 corresponding to the conversion means. Intermediate key updating information is generated every time a bit string conversion is conducted and the information is transferred to the means 131 to 135. On the other hand, the bit string called a key generates the initial condition value of the intermediate key corresponding to each intermediate key by executing linear or nonlinear conversions in an intermediate key generating means 12 against the key from the external and the value is transferred to the means 131 to 135. The means 131 to 135 store the intermediate keys and control the conversion means by transmitting the intermediate keys to the conversion means.  Furthermore, the intermediate keys are updated by receiving the intermediate key updating information generated and transferred by the conversion means under the control of the information.
