Title: Optical pickup device
Inventor: YOSHIDA TADAO
IPC: G11B11/10
Filed: 1988-03-31
Abstract: PURPOSE:To prevent multipath reflection between a laser beam source and an optical disk from being generated when the optical disk with high reflectance is used by detecting the class of a loaded optical disk, and performing the load/unload of an attenuator corresponding to a detected result. CONSTITUTION:An optical attenuator 21 capable of cutting off a laser optical path by a prescribed part is arranged loadably/unloadably freely in the laser optical path between the laser beam source 2 and the optical disk 7. In a state where the focusing of the optical disk 7 after loading can be almost obtained, receiving output SCD obtained from optical detectors 11 and 12 are compared with a prescribed reference level, and the class of the loaded disk 7 is detected by a disk class control circuit 25, and the attenuator 21 is loaded when it is the disk 7 with high reflectance corresponding to the detected result by an optical attenuator driving circuit 22, and when it is the disk 7 with low reflectance, the attenuator 21 is removed. As a result, it is possible to prevent the multipath reflection generated between the beam source 2 and the disk 7 from being generated when the disk 7 with high reflectance is used.

IPC: B65H23/195
Filed: 1990-03-28
Abstract: PURPOSE:To reduce abrupt variation in a coil diameter output by a carousel reel at the termination of a revolution period by computing a variation in the diameter of a coil during a period in which a carousel reel body and a wind-up shaft are rotated simultaneously, from data concerning the thickness of a mate rial to be wound up and a degree of rotation of the wind-up shaft. CONSTITUTION:A measuring section 9 computes the diameter of a coil from a degree of rotation of a wind-up shaft or the like and a degree of wind-up a steel plate until a revolution period is initiated. In this condition, a contact 11 is turned on while a contact 12 is turned off so that an output from the measuring section 9 is delivered directly to a control section 10. During the revolution period, the contact 11 is turned off while the contact 12 is turned on so that an estimating section 13 adds a cumulative value of variations in the coil diameter which have been computed from the degree of rotation of the wind-up shaft or the like and the thickness of the steel plate, to the diameter of the coil obtained just before the initiation of the revolution period, and delivers its output to the control section by way of the contact 12.

Abstract: PURPOSE:To prevent a damage to a magnetic tape attended with an abnormal reel rotation by detecting the decrease in the reel rotating speed with high accuracy based on a tape winding quantity obtained from a rotating speed data of both reels and stopping the driver of the tape. CONSTITUTION:A tape winding quantity data of a winding T reel and a supply S reel is data equivalent to a quantity of a magnetic tape wound on the T reel and the S reel when the tape is driven at a speed being N times of a prescribed speed. When the rotation is decreased due to a fault of a drive mechanism of the T reel or the like, the T reel tape winding quantity data is data larger than a prescribed tape winding quantity data and similarly, sum data is a data larger than the prescribed tape winding quantity data. Thus, a level difference is caused between the sum data and the tape drive is stopped through the detection of the difference. Thus, even in the occurrence of an abnormal drive of the reel in this way, it is detected with high accuracy to stop the tape drive. Thus, a damage to the magnetic tape attended with an abnormal reel drive or the like is prevented in advance.

Abstract: PROBLEM TO BE SOLVED: To prevent user's hands from being in touch with kerosene at the time of mantling and dismantling a valved cap in order to feed kerosene to an oil-feeding tank. SOLUTION: A valved cap 2 to be mantled on an oil-feeding tank 1 is covered with a cover cylinder 4 having a plurality of protruded and vertical ribs 9 around the periphery thereof. A spring 7 is provided between a rotation assist member 6 having a plurality of vertical grooves 8 and a flange of the cover cylinder 4, so that the rotation assist member 6 is constantly pushed downward. Since a given distance L is provided between the inner peripheral wall surface of the rotation auxiliary tool 6 and an opening, and since a portion of the inner peripheral wall surface is provided with ribs, when the oil-feeding tank is elevated, the rotation assist member 6 is automatically lowered.  Since the lower surface of the member 6 is positioned lower than a tip 2a of the valve- bearing cap 2, when rotated holding the rotation assist member 6, the kerosene attached to the tip 2a cannot be in touch with user's hands. Thus, the valved cap 2 can be stably and readily dismantled.
