IPC: B41J2/07
Filed: 1984-04-19
Abstract: PURPOSE:To always maintain the best printing condition preventing the generation of skewed point due to temperature and moisture by detecting the skewing to correct it automatically according to the value of the print skew detected. CONSTITUTION:The surface of a skewed print detector 7 is provided with a print skew detector section 8 along the printing line 6. To detect possible skewed print, after shifted to the side of the detector section 8, the carriage 2 is moved forward to record dots 17 and subsequently, done backward to record dots 18.

Filed: 1982-05-12
Abstract: PURPOSE:To prevent turbulence in an air stream by driving a rack gear, installed at the back of vanes, by means of engagement with a crown gear at the back of the flow-line surfaces, by allowing the vanes to slide in a groove of the plate, and by hindering this variable mechanism from exposure to the flow-line surfaces. CONSTITUTION:Bent cogs are arranged at the rear of a plate 4, which is fitted in a rotary shaft, not illustrated, with the aid of the drive device, not illustrated. When a crown gear 14 excavated with these bent cogs is rotated, this will mesh with a gear member 12, which is incorporated in a housing 15 as its part, installed on the axis 11A of the vane 11, and restricted to move in the gear's 14 revolving direction by a groove 13 provided in a plate 4. Thus the gear member 12 slides along the groove 13 to move the vane 11 in the direction of sliding. Accordingly this drive device is not exposed to the flow line, so that there is no fear of generation of unevenness in the flow lines at the tip of and in the later half of the vane 11. Thus delamination of the fluid's boundary layer can be prevented, and the performance of diffuser enhanced.

Abstract: PURPOSE: To control the production of vortex by a boundary layer so as to reduce noise by forming an impeller so that the blade cross section mounting angle of a blade mounted on the hub of the impeller becomes the maximum near a specified ratio of the diameter of the impeller. CONSTITUTION: An impeller is formed with a hub 2 fixed to a motor and a blade 1 embedded in the outer peripheral surface of the hub 2 in radial direction. Also it is formed so that a mounting angle of a blade cross section near the 70% of the diameter of the impeller becomes the maximum. With this constitution, air velocity becomes higher at a position as it is far apart from the external peripheral surface of the hub 2 in circumferential direction, and a boundary layer 8 is also produced on the outer peripheral surface of the hub 2. In addition, a secondary flow 9 from the pressure surface 3 of the blade 1 to a negative pressure surface 4 is increased, and the secondary flow 9 becomes the flow 10 from the outer peripheral surface of a boss in the circumferential direction of the blade 1. Thus the boundary layer 5 on the negative surface is blown off so as to reduce a flown out vortex 6 for noise reduction.
