Abstract: PURPOSE:To obtain a low vibration light weight impact dot line printer at low cost by a method wherein a dot is successively formed by impact pressure occurring only at an intersecting point part of a ridge of a platen and an edge- like hammer, and a dot line is recorded on paper. CONSTITUTION:When a platen 23 is revolved, intersecting points 25a and 25b of platen edges 24a and 24b on a platen 23 and hammer edges 21a and 21b are relatively moved in the arrow direction. Then, when the intersecting points 25a and 25b have come to specific positions following a recording signal, an impact head is driven to make the hammer edge 21 knock at a paper side. Since only the intersecting points 25a and 25b receive impact pressure, a recording dot 19 is formed with an ink ribbon. When one dot line is completed by repeating recording operation, the paper 18 is sent by a pitch content of the dot line and simultaneously the platen 23 is revolved. Since the platen edge (a) 24a comes near a left end of the adjacent hammer edge (b) 21b, a next dot line is successively formed.

Title: Rotating body for detecting angle of rotation
Inventor: TANAHASHI SHIGETAKA
IPC: G01B7/00
Filed: 1984-12-20
Abstract: PURPOSE:To easily discriminate a normal signal from noise by detecting variation in the quantity of magnetic flux which is caused by recesses and projections formed at the periphery of rotation of a rotating body made of a magnetic body. CONSTITUTION:A recessed part 8 is shallow even on a projection part 22 adjacent to the wide recessed part 8, so the magnetic resistance of a space a13 decreases and becomes equal to the magnetic resistance of a space all formed together with an adjacent projection part 21. Then, a wave b12 of the quantity of cross-linkage magnetic flux at the position is nearly equal in crest value to a wave b11 at another position. Consequently, the output voltage of a pickup coil 16 which is determined by the gradient (time differentiation) of the quantity of cross-linkage magnetic flux decreases in the crest value of neither of waves c12 and c13 even before and behind the wide recessed part 8, so that they are all uniformed. Consequently, when the analog output voltage waveform from the coil 6 is converted into a digital signal, a threshold value having sufficient hysteresis is set, so the normal signal is easily discriminated from noise.
