Title: Optical scanner
Inventor: KAMOTA HIROKI
IPC: H04N1/04
Filed: 1992-04-20
Abstract: PURPOSE:To increase the upper-limit value of a scanning angle by shaping a scanning part so that viscous fluid resistance due to rotation is hardly received and then providing a weight. CONSTITUTION:The scanning part 5 is almost symmetrically in its right-left direction about the axis P of an elastic deformation part 3, a mirror surface 6 which is specularly machined is formed on its top surface, and the weight 7 is fitted to the other end part of the reverse surface. In this case, the air resistance that the scanning part 5 receives is made small by making the external size of the scanning part 5 as small as possible, but the scanning part 6 itself is almost symmetrically in the right-left direction about the elastic deformation part 3, so almost no moment of inertia turning the scanning part 5 in a direction thetaT is generated. Further, the weight 7 is fitted to the edge of the scanning part 5 and then a decrease in the moment of inertia of the scanning part 5 itself is compensated to increase the moment of inertia that the scanning part 5 receives, thereby increasing its angle of turning.

IPC: G11B7/005
Filed: 1984-06-20
Abstract: PURPOSE:To eliminate the influence of the distortion of a playback analog signal by measuring the timing between a data pulse signal generated at the zero-potential point of the playback analog signal and a distortion pulse signal based upon the distortion of the analog signal, and selecting a signal of intermediate timing. CONSTITUTION:The playback analog signal B of recorded information is supplied to comparators 1 and 2 and also sent to a data pulse generating circuit 3. Signals converted digitally by the comparators 1 and 2 are inputted to an AND circuit 7 through an OR circuit 6.

Title: Impeller of complex multivane blower
Inventor: KUMA TOSHIMI
IPC: F04D29/30
Filed: 1979-10-04
Abstract: PURPOSE: To eliminate exfoliation of gas stream and increase the blowing efficiency by constituting a vane wheel from inside and outside cascades.  
     CONSTITUTION: As for the impeller of this complex multivane blower, the inside vane 3 cascade and the outside vane 4 cascade are arranged between a main plate 1 and a side plate 2, and a gap 5 is formed between the inside vane 3 cascade and the outside vane 4 cascade. When the impeller is used for a centrifugal blower, the inside vane 3 cascade and the outside vane 4 cascade act as two independent vane wheels each having different outer diameter. As gas is discharged from the inside vanes 3 to a gap 5 once, the difference of speed on the front and back sides of the vane which is formed in the inside vanes 3 and a small exfoliation formed are dissolved, and the gas flows into the outside vanes 4 in the form of an uniform flow. Thus, exfoliation of gas flow is not generated in blowing, and a large blowing efficiency can be obtained even if the inlet angle β11 is made as small as possible, and the exit angle β22 is made as large as possible.
