Title: Optical printing head
Inventor: ITO TETSUYA
IPC: B41J2/455
Filed: 1988-06-29
Abstract: PURPOSE:To realize the multivalent of a dot by dividing one scanning cycle into different time and turning each light irradiation means ON/OFF at every divided time and combining different ON-times. CONSTITUTION:The cycles of a strobe signal is (1/7)F, (2/7)F and (4/7)F as shown by a drawing and combined to make it possible to control the light emitting time of the arbitrary LED element within one scanning cycle in eight stages of 0, (1/7)F.d-(7/7)F.d in total. Moreover, the gradation control of eight stages is realized by data outputs of three times. Herein, d is the duty ratio of the strobe signal and variable within a range of 0-1. Further, a line synchronous signal F is set by F=1/f=Vp.P1 (Vp; process speed and P1, printing density). By controlling the irradiation energy to a photosensitive body within one scanning cycle, multivalent of a higher level becomes possible within the reduced number of times of data output.

Title: Gear
Inventor: MORIKAWA KUNIHIKO
IPC: F16H1/06
Filed: 1989-06-24
Abstract: PURPOSE:To reduce vibromotive force due to gear mesh by forming a gear supporting shaft into a two-layer structure, a solid internal shaft and a hollow external shaft, so that bending load is undertaken at the internal and external shafts and either one of shafts is only served as a power transmitting shaft. CONSTITUTION:As bending load resulting from the mesh of a gear 1 is undertaken at both shafts 2a, 2b of great bending rigidity during power transmission, the deflection of a shaft 2 is reduced. The mesh error of the gear 1 due to the deflection of the shaft 2 is therefore reduced and vibromotive force resulting from the mesh of the gear 1 is suppressed to a small level, and also lower strength of the gear due to lop-sided contact can be avoided. On the other hand, as power transmission is taken only by the hollow external shaft 2b of low torsional rigidity, the variation of transmitting power is absorbed by the torsion of the hollow external shaft 2b, and the transmission of vibromotive force, if any, due to the mesh of the gear 1 can be suppressed to a small level.

Filed: 1990-06-22
Abstract: PURPOSE:To discriminate or remove the false image due to the multipath reflection from video data by deciding that video data having the possibility of the false image is a true false image when the counted value of the frequency of appearance of video data exceeds a prescribed number. CONSTITUTION:An image memory 3 is stored with video data of one image plane to be sent to a display unit 4. A video data input part 5 reads the video data out of the memory 3 and supplies it to a false image data decision part 7. The decision part 7 decides that the video data closest to a radar installation place is a real image and farther video data is possibly a false image when there are plural video data in the same direction. A video data processing part 8 compares the counted value of the frequency of appearance with the prescribed value M of the frequency of appearance of the false image set by a condition setting part 6 and decides that the video data which is possibly the false data is a true false image when M < N, thereby erasing the video data or adding and outputting discrimination data on the false image to a screen memory 3.
