Title: Data output method
Inventor: YOSHIDA HITOSHI
IPC: G06T1/00
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To set a dot data so that a character composition line width becomes a width corresponding to an outline data. SOLUTION: When a character is printed, the character is stored in an outline data form beforehand. When the outline data are superimposed on a pixel screen to transform into a dot data, it is judged whether or not the number of width directional character composition lines of the dots to be formed into character composition lines 44 composing a character corresponds to the widths specified for each character composition line 44, and if not, the outlines 46 of the character composition lines are shifted. By shifting the outlines, the number of the width directional composition lines of the dots to be formed is made to correspond thereto. On the other hand, if the number corresponds thereto, the outlines 46 are not shifted. Thus, after an outline data has been transformed into a dot data, it is visibly outputted.

Title: Seeder for plant seed
Inventor: WATANABE MASASHI
IPC: A01C7/04
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a seeder for plant seeds capable of carrying out seeding operation while supporting a seeding box by a supporting member. SOLUTION: A plant seed is charged into a housing recessed part 2f by a suction machine 6. An opening and closing valve is opened by rotating a wing nut 2k to make suction force maximum. Since a pair of supporting arms 3 is mutually and independently oscillated, a seeding box 2 is inclined to each direction while supporting the seeding box 2 on a supporting arm 3 and the plant seeds can be spread over whole area of a absorbing plate 2e. Since air is sucked from housing recessed part 2f side of the absorbing plate 2e to closing space side by a suction machine 6, the plant seeds are absorbed into each small hole 2d of the absorbing plate 2e.  After absorption, the seeding box 2 is inverted and superposed to a tray 5 for seeding put on a pedestal 4 and when absorbing force is reduced by rotating the wing nut 2k, plant seeds are dropped from each small hole or to the tray 5 for seeding and plant seeds are sown. Seeding operation can be carried out while supporting the seeding box 2 on the supporting arm 3 and the workability can be improved thereby.
