Title: Optical disk servo system and its device
Inventor: NAKAGAWA KATSUJI
IPC: G11B7/09
Filed: 1986-04-08
Abstract: PURPOSE:To attain a stable tracking action by detecting the different frequency signals from the reflected light of a laser spot condensed on an optical disk and performing the tracking of the recording/reproduction laser spot so that a fixed ratio is secured for intensity of the frequency signal. CONSTITUTION:The laser light 1 delivered from a light source is condensed on a recording plane 6 of an optical disk 5 through a polarized beam splitter 2, a 1/4 wavelength plate 3 and a condenser lens 4. The plane 6 of the disk 5 includes guide parts 7 and 8 having different reflection factors from the plane 6 and also different cycles formed along both sides of an information recording track. Thus the reflected light sent from the plane 6 are irradiated on a photodetector 9 through the lens 4, the plate 3 and the splitter 2. In a rotation mode of the disk 5 the signal detected by the detector 9 contains two different frequency components according to changes of reflection factors of both parts 7 and 8. Thus the condensed laser spot can be tracked to a fixed position between both parts 7 and 8 by performing the position control of the lens 4 so that the ratio between both frequency components is fixed for the signal detected by the detector 9.

Abstract: PURPOSE:To facilitate switching of a charge hopper by ventilating hot air to a drying chamber while dropping the cereals to the chamber to dry the cereals, and operating an exhauster after a predetermined time is elapsed from the time of starting cereals charging to a dryer. CONSTITUTION:A cereals dryer ventilates hot air generated from a hot air device to a cereals drying chamber 9 while delivering and falling cereals from an upper cereals storage chamber 8 to the lower chamber 9 and dries the cereals by sucking and exhausting dry air by an exhauster 18. The dried cereals are covered through a delivery valve 12 and a cereals collecting trough 14. A charge hopper 23 having a lower part as a rotation starting point is provided at a lateral dryer wall 5, and opened at the time of charging the cereals. In such a dryer, when a charge start switch is pressed, the exhauster 18 which is operated for a predetermined time is operated. Thus, suction of the hopper 23 by the suction force of the exhauster 18 is eliminated to facilitate opening of the hopper 23.

Filed: 1979-06-29
Abstract: PURPOSE: To provide a correct printing operation by a mechanism wherein a selective stopping action of a type wheel is used simultaneously as a signal for starting a pressing action of a platen roller.  
     CONSTITUTION: When the rotation of a motor MO is transmitted to a type wheel 1 through gears 7, 6, driving gear 5, planetary gear 4, holding disc 3 and driving shaft 2 and the desired type comes to a position directly before the printing position, a printing instruction is inputted to an electromagnetic device Mg to deenergize the latter. The deenergization causes a bent portion 16b of a change-over lever 16 to push a ratchet pawl lever 19, thereby restricting a ratchet wheel 9 and stopping the type wheel 1, while making a pin 19a retract from a notch 14a of a cam disc 14, and making platen roller 10 revolve through a platen shaft 12, and causes the roller 10 to press the type wheel 1 for printing on the printing paper 20. After completion of printing, the rotation of an eccentric cam 18 pushes a pin 16c upward, thereby causing a pole contacting portion 16a of the lever 16 to be attracted to and held on the permanent magnet of the device Mg. Simultaneously, the engagement between the lever 19 and the ratchet wheel 9 is released, the pin 19a is advanced into the notch 14a and the type wheel 1 is rotated.
