Filed: 2000-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a circulation type food and drink conveying device to enable reliable transfer of a plate of sushi, separation of the adjoining plates of sushi with a comparatively light force, and prevent the damage of a conveyance passage. SOLUTION: Since first and second magnets 20 and 17 are arranged such that the magnetic poles of the respective magnets face opposite to each other, when food and drink containers are placed on a conveyance passage, the first and second magnets 20 and 17 are brought into a position relation that the same magnetic poles face each other, the first magnet receives the repulsion force of the second magnet and is brought into a state to be stabilized between the second magnet and a second magnet adjoining thereto. In this case, since, when the second magnet is run in a circulating manner in a given direction, the first magnet tends to hold the stable position described above, it is circulated and run at the same speed as the running speed of the second magnet.  Since a repulsion force is present, in a manner described above, between the second magnet and the first magnet, the food or drink container can be lifted with a comparatively light force and the conveyance passage is hardly damaged during circulation conveyance of the food and drink container.

Title: Optical disk device, information processor, optical disk recording method and method for manufacturing optical disk device
Inventor: SUGANO AKIHIRO
IPC: G11B7/0045
Filed: 2000-08-01
Abstract: PROBLEM TO BE SOLVED: To detect an ATIP signal from a CD-R at high recording speed without using a sample-hold circuit having high-speed responsiveness or a highly precise sample signal. SOLUTION: The light-emitting power of a laser diode 22 emitting a laser beam for recording data on an optical disk is detected by a photodiode 23. The signal of light-emitting power when recording power is outputted is selectively outputted to a sample-hold circuit 34 by opening and closing a SW 34a by a sample signal W from this detection signal. The sample-hold circuit 34 samples and holds the level of an outputted detection signal. This held value is compared to a reference voltage VrefC by a voltage comparator 54. On the basis of the result, a CPU 17 restricts deterioration of light-emitting power by controlling to enlarge only a part for reproduction power or a part for reproduction power and recording power in electric currents to drive the laser diode 22.
