Title: Discharge device for pulverulant materials on flat lower surface
Inventor: SHINOZAKI TAKESHI
IPC: B65G25/04
Filed: 1985-04-25
Abstract: PURPOSE:To allow a simple configuration to be employed so as to reduce the occurrence of troubles by configurating a device in such a way that a frame which is installed in parallel with a flat lower surface to reciprocate as required, with scrapers which are elevated as required, so as to be elevated linked with the reciprocating movement of the frame. CONSTITUTION:When a drive wheel 11 is rotated to the direction as shown by an arrow head starting from the condition as shown by the figure, a pinrack 10 allows a rubbing frame 8 to move to the left. At this moment, as a stopper 18 prevents a main frame 5 from moving, only the rubbing frame 8 is allowed to move. Accordingly, an engaging part (not shown) installed on the rubbing frame 8 allows a lever 14 installed on a scraper 13 to rotate counterclockwise. This causes a left scraper 13 to be elevated, and simultaneously, a right scraper 13 to be lowered allowing the right scraper 13 to rake pulverulant materials up to a discharging outlet 3, and also allowing the left scraper 13 to slide just above the pulverulant material. When this device is operated reversely, the left and right scrapers are operated in a reverse manner. This configuration allows a simple device to be employed so as to reduce the occurrence of troubles enabling pulverulant materials to be discharged while they are classified by the size of materials.

Title: Optical beam scanner
Inventor: BABA NOBUYUKI
IPC: G02B26/10
Filed: 1987-04-09
Abstract: PURPOSE:To permit a simple means to reduce the deviation of a beam projected place on a scanned surface in the main scanning direction of scanning light, which is caused by mode hopping, by providing a diffraction grating for displacing the scanning length on the scanned surface in the main scan direction in front of a hologram disk. CONSTITUTION:When stuff with such a characteristic that shifts from a locus (a) to a locus (b) by mode hopping is employed as the diffraction grating 8, an incident angle on the hologram disk 6 changes and a diffraction angle becomes nonparallel. However, even if the beam moves in the radius direction of the hologram disk, diffraction width in the axis X on a screen is the same as the beam moves to the locus (b) from the locus (a). By setting the interval between the loci (a) and (b), the exposure angle of holograms and the spacial frequency of the diffraction grating 8 to appropriate values, the deviation of the beam position in the main scan direction can be corrected. Thus, the shifting amt. of a scanning light spot, which is caused by the mode hopping of semiconductor laser, can be minimized in the main scan direction in which information is read out.
