Filed: 1987-06-10
Abstract: PURPOSE:To reduce labor, by detecting consumption of seedling in one stroke and the amount of seedling left at every seedling guide face of seedling stand and judging whether the amount of seedling left is enough to supply seedlings for the next stroke. CONSTITUTION:A control part 21 detects an amount l of seedling raked by a planter 5 by a sensor 19 for the raked amount, detects an amount n of seedling laterally transferred on a seedling stand 7 by a sensor 23 for lateral transportation and detects the times m of transplantations by a rotary sensor 20 for transplantation. A calculating means 21a calculates consumption of seedling (m/n.l) by the raked amount l, the laterally transferred amount n and the times m of transplantation. The consumption of seedling is subtracted from the original retention amount L of seedling to calculate the amount of seedling left (L-m/n.l), which is shown on a display 27.

Title: Input device for monitoring station
Inventor: EHATA TSUTOMU
IPC: G06F3/0482
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To eliminate a deletion or erroneous registration of data which is caused by a misoperation of a monitor at beginner's level by showing an executable job item on the screen of a display device according to the level of monitor. SOLUTION: When a monitor at level 1 performs a job, the ID number of the monitor is inputted via a key of an input part. A discrimination device DA retrieves the level 1 via an discrimination table DT, and the retrieved level 1 is inputted to a selection device SA. The device SA selects the job item from a job table ST and shows the selected items on a display device CRT. Therefore, the customer information and a sate monitoring job can be executed by the monitoring items and the execution of other job is impossible. Thus, the job item is shown on a screen according to the level of monitor. As a result, a monitor at beginner's level is unable to register nor change the equipment and therefore, a misoperation which is caused via the key of the input part can be prevented.
