Title: Transmission line acquisition control system
Inventor: TAKAHASHI YOSHIKAZU
IPC: H04L29/08
Filed: 1983-08-17
Abstract: PURPOSE:To realize a semi-duplex transmssion system with a few number of lines by transmitting and receiving a transmission line acquisition request signal and a transmission line acquisition permitting signal through two signal lines. CONSTITUTION:In transmitting a signal from a CPU1 to a CPU2, a data linkage adaptor CLA3 transmits the transmission line acquisition request signal X to an opposite side adaptor CLA'3' through a signal line 41. The CLA'3' transmits the transmission line acquisition permitting signal Y through a signal line 42 on the condition that a reception request is generated. When a signal Y is not obtained within a prescribed time after the transmission of the signal X, the CLA3 generates an error signal. When the CLA3 receives the signal X from the CLA'3' during the generation of the signal X, the CLA3 transmits the signal Y to the CLA'3' on the condition that the reception request is generated. This is applied to the transmission line acquisition control to transmit signal from the CPU2 to the CPU1.

Abstract: PURPOSE:To improve the adaptability to a scanning exposing of a scanner system and to allow handling under a safe light as well as to lessen the generation of fogging and the fluctuation in sensitivity by the stray light in an exposing and heat developing device by providing a specific photosensitive layer. CONSTITUTION:The photosensitive layer having SH/SL>=2.0 when the inverse number of the exposure to apply the optical density higher by 0.3 than a fogging density is defined as the sensitivity and the sensitive layer having SH/SL>=2.0 when the sensitivity is defined at the time of exposing for 0.3 microseconds as SH and the sensitivity at the time of exposing for 30 seconds as SL is formed. The optical density refers to the reflection density when the images are formed on a reflecting base and to the transmission density when the images are formed on a transparent base. Satisfying of both the adaptability to the scanning exposing by the scanner and the stability to the safe light is not possible at SH/SL<2.0. The adaptability to the exposing by the scanner is improved and the handling under the safe light is facilitated in this way. The fogging and the fluctuation in the sensitivity by ray leakage are thus obviated.
