Title: Method for transmitting digital signal and its processor
Inventor: IZUMIDA MORIJI
IPC: H04L1/00
Filed: 1985-04-26
Abstract: PURPOSE:To improve the reliability of a transmission signal between recording and reproducing devices for a digital signal at the transmission of the signal by transmitting the output of a reproducing signal processing means through a recording signal processing means in an equipment on a transmitting side, and receiving the transmitted signal by a recording signal processing means through a reproducing signal processing means in the equipment on a receiving side. CONSTITUTION:Digital data 6a detected and corrected by a reproducing signal processing circuit 11a are inputted to a recording signal processing circuit 12a to add an additional signal such as an error correcting parity and a synchronizing pattern to the input signal 6a and the added signal is outputted to a reproducing signal processing circuit 11b on the recording side. The circuit 11b detects and corrects an error generated in a transmission line A at the time of transmission from a digital VTR 10a to a VTR 10b and outputs the corrected signal to a recording signal processing circuit 12b as an original digital signal 7b. The circuit 12b adds an additional signal such as an error correcting parity and a synchronizing pattern to the digital signal 7b sent from the circuit 11b and outputs the added signal to a magnetic recording/reproducing device 13b. The device 13 records a signal 8b outputted from the circuit 12b in a recording medium.

IPC: G02B5/20
Filed: 1992-04-09
Abstract: PURPOSE:To obtain a photosensitive transfer material suitable for dry transfer to a base body having a rough surface, and to obtain an image forming method using this material. CONSTITUTION:On a temporal supporting body, there are formed an alkali-soluble thermoplastic resin layer, intermediate layer, and photosensitive resin layer in this order to obtain a photosensitive transfer material in a manner that adhesion strength between the thermoplastic resin layer and the temporal supporting body is smallest. Picture images are formed on a permanent supporting body with using this photosensitive transfer material by tightly adhering the photosensitive resin layer and the permanent supporting body while at least heating, peeling the interface of the temporal supporting body and the thermoplastic resin layer, exposing the photosensitive resin layer to light through the thermoplastic resin layer and the intermediate layer, and developing the pattern. In this process, the alkali-soluble thermoplastic resin layer and the intermediate layer are removed with using such a developer that can develop the alkali-soluble thermoplastic resin layer and the intermediate layer but does not substantially develop the photosensitive resin layer, and then the photosensitive resin layer is developed to form picture images. Thereby, overfatigue of the developer or irregular development can be prevented.
