Title: Pneumatic tire
Inventor: HIGUCHI TEI
IPC: B60C13/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent exfoliation at a film layer from generating by cutting out parts of a film sandwiched with a carcass layer and a finishing layer, and providing parts at which the two layers are directly joined together. SOLUTION: Cutouts 16 are provided on a film part sandwiched with a carcass layer and a finishing layer, and hence parts at which the two layers are directly joined together are provided. The cutouts 16 are formed by pricking, and when mean cutout rate per unit area against the area where the finishing layer and the film layer are piled up is at least over 5%, exfoliation can be restrained, but it is more favorable to be over 30%. When the cutout rate is over 80%, it can be formed but stiffness of the film is reduced, the guide mechanism of a forming machine can not be normally worked, centering becomes difficult, and hence the mean cutout rate per unit area of the film is desirable to be under 80%.

Title: Time counting device
IPC: G06F1/14
Filed: 1992-03-27
Abstract: PURPOSE:To detect the correct time sequence relations of occurrence of events in accordance with time stamps by adding contents of a clock, which are updated by hardware and discriminate the time sequence relations of occurrence of events, and a correction value set to a register by a software instruction. CONSTITUTION:A clock 1 is constituted as a counter, and the time is first set as the initial value and is periodically updated. In the case of the occurrence of error of the clock 1, contents of the clock 1 are rewritten with the correct time by the software instruction executed by an information processor to correct the clock 1. Even if error of a clock occurs, its value is not set again. Since contents of the clock 2 does not regress, time sequence relations of occurrence of plural events are always correctly detected by referring to contents of the clock 2 which are recorded as time stamps in an external storage device thereafter. Thus, information effective for fault analysis is obtained, and the version of a file is correctly discriminated.

Title: Laminate and method for laser marking
Inventor: HIRABAYASHI SATOSHI
IPC: B41M5/26
Filed: 1990-03-20
Abstract: PURPOSE:To enhance durability and to make the rewriting of a mark difficult by providing a layer permitting transparent or translucent laser beam to transmit on a layer discolored by the irradiation with laser beam. CONSTITUTION:A laminate for laser marking wherein a layer permitting transparent or translucent laser beam to transmit is provided on a layer discolored by the irradiation with laser beam is irradiated with laser beam to perform marking. Since only the laser beam discoloring layer is marked when the laminate for laser marking is irradiated with laser beam through the laser beam transmitting layer, the laser beam transmitting layer acts as a protective layer and durability is markedly enhanced. Further, since marking is applied by laser beam through the laser beam transmitting layer as the protective layer, the rewriting processing such as erasure or correction of a mark is difficult and the forgery of individual data becomes difficult. Further, this laminate can correspond to small quantity and multikind high speed printing.
