Abstract: PURPOSE:To improve the operating efficiency of a line and to reduce collision probability by allowing the mixture of pre-assign and demand systems, assigning the system corresponding to the traffic characteristic of a station and applying change of pre-assign slot/system changeover with respect to a change in the traffic characteristic. CONSTITUTION:A synchronizing signal is polled from a master station 10 to all slave stations 20, and each slave station generates a slot timing by time division based on the synchronizing signal. The communication system for each slave station and pre-assign slot information are stored in a storage device 12 from a terminal equipment 11. Then the pre-assign slot information is sent to a communication equipment 13 by the start of the terminal equipment 11, a data link so far is cut off once and a data link confirming request is sent to each slave station 20. The communication system of the slave station 20 is decided and in the case of the pre-assign system, a data is sent through only the stored assign slot. In the case of the demand assign system, an idle slot is selected from idle slot information of the synchronizing signal and reservation request is applied from the slot.

IPC: A01G31/00
Filed: 1993-05-25
Abstract: PURPOSE:To obtain a method for diluting a concentrated liquid fertilizer used for cultivating plants in which the fertilizer can stably be diluted and diffused for a long period without applying any operation from the outside in diluting the fertilizer to be applied to the plants. CONSTITUTION:A concentrated liquid fertilizer is stored in containers made of a semipermeable membrane, a wholly permeable membrane and an impermeable membrane, etc., and hermetically closed therein.

After the lapse of a while, 'water' is taken into the containers by a permeating phenomenon to increase the pressure in the containers. Salts can continuously be released into the water by the swelling pressure to stably dilute or diffuse the salts for a long period without relying on the man power or a mechanical apparatus. Thereby, the purpose can be achieved.

Filed: 1988-06-30
Abstract: PURPOSE:To reduce the quantity of hardware by inputting a companding rule switching signal and a sign code to a full adder directly so as to omit a switching circuit depending on the combination of the signals. CONSTITUTION:The title circuit consists of a full adder circuit 3n receiving the output of a low-order bit except a sign code of a linear code outputted from a linear code conversion circuit 1 as one input, receiving a companding rule switching signal as part of other input and receiving the sign code of the linear code as a carry input, and an inverting circuit 4n inverting the output of the full adder 3n according to the sign code of the linear code.
