Inventor: ITO SADAO
IPC: H04B7/26
Filed: 1987-10-12
Abstract: PURPOSE:To build up a system having the same function as a conventional system even when a radio line control station is abolished by providing a chan nel changeover means switching alternately a 1st radio channel and a 2nd radio channel and applying transmission/reception to a radio base means and a mobile radio means. CONSTITUTION:A radio base means 30 selects other radio base means suitable for setting the 2nd radio channel and the channel used for communication with the selected radio base means is set as the 2nd radio channel. A gate exchange means 20 receiving the setting command sends a communication signal during communication through the 1st radio channel to the 2nd radio channel, switches the 1st and 2nd radio channels alternately by a channel switching means 11 during the switching transmission/reception period. Then the radio base means 30 confirms it that the communication quality by the 2nd radio channel is a prescribed value or over and continues the correspondence through the 2nd radio channel only. Thus, even when the radio line control station is aborted, the system with the same function as that of a conventional system is built up.

Title: Method for estimating dither halftone picture
Inventor: HIRATSUKA SEIICHIRO
IPC: H04N1/393
Filed: 1985-11-15
Abstract: PURPOSE:To obtain a picture approximate to an original halftone picture by selecting the optimum scan opening for each picture element by the prescribed processing after setting plural types of scan openings together with scanning carrier out over the dither picture and counting the number of white picture elements existing within the scan opening to define this count value as the estimated halftone picture value. CONSTITUTION:The dither picture within each scan opening is compared with the binary picture obtained from a halftone picture produced based on the ratio between the white and black areas in the scan opening through a dither matrix in the scan opening for each scan opening. Thus the only scan opening is selected by the 1st selection method. While the prescribed arithmetic processing is carried out according to the white and black areas in each scan opening and the only scan opening is selected by the 2nd selection method. Thus the only scan opening is selected for each picture element of the halftone picture to be estimated by means of both the 1st and 2nd selection methods. As a result, the scale of a digital electronic circuit is reduced and at the same time the working speed of this circuit is increased.

Title: Recorder having seamed endless photosensitive body
Inventor: FURUSHIMA TADASHI
IPC: G03G21/14
Filed: 1986-10-29
Abstract: PURPOSE:To make the record processing time immediately after the next recording is started shortest, by counting pulses synchronizing with the movement of a photosensitive body at every seam and stopping the photosensitive body at a prescribed count value which sets the starting end of the effective surface of the photosensitive body as a charging position when the recording is terminated. CONSTITUTION:When a seam is detected, a seam detecting sensor S6 initializes a count value. Then drive of a photosensitive body is instructed to a main motor 210 and a recording cycle of numbers, at which an effective image forming surface can be formed in correspondence to the length of the effective image forming surface of the photosensitive body except the seamed section and the size of a recording medium, is repeatedly started. When the number is exceeded, the recording cycle is started after the count value reaches a value, which is obtained when the count value corresponding to the distance ranging from an electrifying charger 208 to the sensor S6 along the moving direction of the photosensitive body is subtracted from the sum of the count value corresponding to the full length of the photosensitive body and the count value corresponding to the distance ranging from the seam to the starting end of the effective surface of the photosensitive body. Then, when the count value reaches a prescribed value, the stopping instruction is given to a main motor 210.
