  • Publication number: 20070183277
    Abstract: An optical pickup irradiates laser light upon a track of an optical disk and receives light reflected therefrom. A tracking actuator shifts an objective lens of this optical pickup in a tracking direction. A tracking error signal detection circuit outputs a tracking error signal based upon the reflected light received by the optical pickup. A phase compensation circuit generates a tracking drive signal based upon the tracking error signal, and outputs this tracking drive signal to the tracking actuator. A balance compensation value calculation circuit calculates a balance compensation value for the tracking error signal according to the tracking drive signal outputted by the phase compensation circuit. And a balance compensation circuit adds this balance compensation value to the tracking error signal detected by the tracking error signal detection circuit, and inputs this compensated value to the phase compensation circuit.

  • Publication number: 20060226358
    Abstract: Firstly, the following check chip is set up into a heater: A check chip onto which a sample has been picked up by wiping out the surface of a check target, or a check chip formed by absorbing and collecting the sample into a filter. Here, the filter has been set up in a vibration-type or heating-type portable-type absorption probe in an attachment/detachment-capable manner. Secondly, a sample gas generated from the heated check chip is analyzed using a tandem-type mass spectrometer. This makes it possible to simplify the sample pick-up from various types of check targets, and to shorten the pick-up time and the checking time.

  • Publication number: 20060158978
    Abstract: There is provided an optical disk apparatus having a function of speedily calculating the amount of optical axis misalignment of an optical pickup to allow a wobble signal to be obtained early when initially spinning up an optical disk. Servo control means 27 turns the focusing servo on while turns the tracking servo off when initially spinning up an optical disk. In this state, optical axis misalignment calculating means 28 calculates the amount of optical axis misalignment X by a calculation formula X=[(A+B)?(C+D)]/(A+B+C+D) [%]. Subsequently, offset adding means 29 adds an offset value according to the amount of optical axis misalignment X to a tracking drive voltage after turning the tracking servo on. Then, wobble detecting means 30 detects a wobble signal by (A+B)?(C+D) after the offset value is added.

  • Publication number: 20060072389
    Abstract: An optical disc recording/reproducing apparatus according to the present invention determines the state of recording of an optical disc on the basis of the detection period of longest pits recorded on the optical disc wherein the period is changed with the acceleration of the rotation of the optical disc until a predetermined rotation speed is achieved. This enables rapidly determining whether the optical disc is unrecorded disc or a recorded disc.

  • Publication number: 20050219978
    Abstract: A disk apparatus includes a light emitter that emits a light beam to be reflected on the optical disk, a light detector that detects a reflected light beam that is reflected from the optical disk, the light detector also outputting detection signals based on the amount of the reflected light beam detected, and a controller determines whether the optical disk is a recordable optical disk or not based on the detection signals. The controller also shifts a spot on the light detector at which the reflected light beam is incident by adjusting the focus point of the light beam on the optical disk in the radial direction when the controller determines that the optical disk is not a recordable optical disk. A wobble signal can be detected with high precision at low cost even when the position of the light detector is not balanced in the radial direction.

  • Patent number: 5204268
    Abstract: A method for applying a droplet of a liquid sample from a sample applying nozzle, which is movable between a retracted position and a sample applying position, to a test film which contains a reagent which will react with a liquid sample and give rise to a change in optical density, includes providing the leading edge of the sample applying nozzle with a test film sensor. Prior to the application of the droplet of the liquid sample to the test film, the sample applying nozzle is moved down until the test film sensor comes into contact with the test film, and the distance by which the sample applying nozzle was moved down is stored. At the time the liquid sample is applied to the test film, the distance by which the sample applying nozzle is moved down is adjusted in accordance with the stored distance so that the sample applying nozzle is moved down to a sample applying position spaced a predetermined distance from the test film.
