Abstract: PURPOSE:To write a picture to all pages of a writing sheet unforcedly at a stable attitude by a copyist by providing a key indicating the movement of the writing sheet and a sheet-movement control means shifting the writing sheet only by movement in response to the depressing time of the key. CONSTITUTION:The feeding key of a key input section 18 is depressed in a short time when there is a page mark 12 on the shaft 13 side, and the return key of the input section 18 is depressed in a short time when there is the page mark 12 on the shaft 14 side, thus detecting the depressing in a short time of the feeding key or the return key by a counter 24 in a main control section 17, then forward-rotating or reverse-rotating a pulse motor 15 for a fixed time through a sheet drive section 20. Consequently, a writing sheet 11 is shifted in the direction of the arrow (a) or (b) only by a fixed quantity such as a quar ter page. The sheet 11 is moved while a position counter not shown in the figure is updated in the main control section 17. The process is repeated, the page mark 12 is positioned at the upper end of the location C of writing written at an enforced attitude by a copyist, and a picture is written to the sheet 11.

Title: Cutter device for hole machining
Inventor: ITO YOSHIICHI
IPC: B23B29/03
Filed: 1991-08-01
Abstract: PURPOSE:To prevent a chattering phenomenon by uncombinatorially arranging cutting blades with a negative rake angle and cutting blades with a positive rake angle and by reducing the number of the cutting blades with the positive rake angle smaller than the number of the cutting blades with the negative rake angle. CONSTITUTION:Cutting blades 2, 3, 4 with a negative rake angle and a cutting blade 5 with a positive rake angleare arranged with equal intervals in irregular order along the circumferential direction, and the number of the cutting blades 5 with the positive rake angle is made smaller than the number of the cutting blades 2, 3, 4 with the negative rake angle. Consequently, resonance is not generated due to the change of cutting resistance and it is possible to prevent a chattering phenomenon and to keep feed per tooth for each cutting blade constant, and accordingly, abrasion of each cutting blade comes to be constant. That is, it is possible to make favourable roundness, too.

Title: Eccentricity value measuring apparatus for rotor
Inventor: MORIWAKI SACHIOSA
IPC: G01B7/00
Filed: 1987-08-31
Abstract: PURPOSE:To enable precise measurement, by mounting a rotor on a magnetic disc having a magnetic signal recorded in a ring to detect a decentering of the rotor depending on changes in the amount of offtrack between the magnetic signal and a magnetic head. CONSTITUTION:A magnetic disc 11 is mounted on a rotating shaft 14 in such a manner that the center of a ring of a magnetic signal 12 recorded thereon coincides with that of the rotating shaft 14 to bring a magnetic head 8 into contact with the magnetic signal 12. The magnetic head 8 is positioned so that an output from the magnetic head 8 reaches a specified value. Then, a motor 13 is operated to rotate the magnetic disc 11 with the rotating shaft 14. In this case, when the rotation of the rotating shaft 14 is decentered, the amount (x) of offtrack between the magnetic head 8 and the magnetic signal 12, and hence, an output voltage from the magnetic head 8 changes according thereto. This causes a change in a detection signal to be inputted into a signal processor 15 from a length measuring meter 9, thereby enabling accurate measurement of the amount of eccentricity of a rotor with the detection of the change in the signal.
