Abstract: PROBLEM TO BE SOLVED: To impartially assign a band when each subscriber device makes a similar request to a common band utilizing request by the same number of bands from information sources in the transmission bands commonly shared by the information sources and to attain communication at a high throughput for the subscriber devices. SOLUTION: All subscribers inform an intra-station device about a common band use permission request REQ1j by each unit time and on the occurrence of the request REQ1j (S1), the request REQ1j is received as a fetch result REQ2j (S2). When a mask 2 for the REQ2j sets all '0s' to a mask result REQ3j (S4, Y), the mask 2 is cleared (S5), and a check sequence denoting the presence of request is replaced (S6). Furthermore, when the REQ3j sequentially goes to '0' and the REQ3j reaches all '0s' (S7, Y), a mask 1 is cleared by each unit time (S8). The request REQ1j is revised to be validated by each unit time in this way to assign a band to a request that is once invalidated when the request is validated on the way of the unit time in the case request is again made for a succeeding unit time.

Title: Hard roller and photographic developing device using the same
Inventor: ENDO YASUHIRO
IPC: G03D3/00
Filed: 2000-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a hard roller capable of completely removing water adhering to photographic paper by nipping the photographic paper to which the water adheres, and a photographic developing device having the hard roller and forming an excellent image. SOLUTION: Since the hard roller 54 has water absorptivity, the water of the photographic paper 44 is easily absorbed by the roller 54. Since the average roughness of the surface 54S of the roller 54 is set within 1.3 μm to 2.1 μm, the water adhering to the paper 44 adheres to the surface 54S of the roller 54 by squeezing. At such a time, it adheres thereto as a thin water film, so that its evaporation rate is high. Since the water adhering to the hard roller is easily disposed from the surface 54S, the water film adhering to the surface 54S by squeezing a sheet of photographic paper is completely removed before squeezing the next photographic paper. Consequently, the water adhering to the surface 54S is completely removed when squeezing the next photographic paper. Thus, the excellent image is formed on the photographic paper.
