  • Publication number: 20040005261
    Abstract: A plasma sterilization apparatus to prevent color change or hardening of materials, e.g., polymers, by generating plasma in a separate plasma generation chamber and supplying it into a sterilization chamber containing an article to be sterilized. A plasma generation chamber includes electrodes installed in close proximity to each other, preferably separated by 0.5-40 cm, to generate plasma with high density even with a small capacity high frequency power source. The electrodes are connected to a high frequency power source to generate the plasma. An injection heater evaporates an aqueous hydrogen peroxide solution used as a microcidal agent, and injects the resulting vapor along with air into the plasma generation chamber. A sterilization chamber communicates with the plasma generation chamber at a remote position through a control valve. A vacuum pump is connected to the sterilization chamber, to form a vacuum state in the sterilization chamber.

  • Publication number: 20040004786
    Abstract: The present invention is a perpendicular writer having an air-bearing surface, a main pole with an extension, and return pole, and a back gap closure intermediate the main pole extension and the return pole. The main pole includes a top magnetic layer and a soft magnetic underlayer separated by a nonmagnetic spacer. The main pole extension is in direct contact with the main pole and recessed from the air-bearing surface. The top magnetic layer forms a trailing edge of the main pole at the ABS and has a magnetic moment greater than that of the soft magnetic underlayer. Further, the top magnetic layer and the soft magnetic underlayer are anti ferromagnetically coupled through the thin nonmagnetic spacer. The nonmagnetic spacer has predominantly 111-crystalline texture and promotes reduction of coercivity and grain size along with an increase of anistropy of the top magnetic layer material.

  • Patent number: 6674697
    Abstract: An apparatus for managing defects and recording and/or reproducing real time data for a recording medium. The recording and/or reproducing apparatus stores information representing use or non-use of linear replacement defect management in which a defective area on the recording medium is replaced with the spare area, in order to record real time data on the recording medium. While maintaining compatibility between the defect managing method and a defect managing method based on a current DVD-RAM standard, i.e., while allowing a report of the fact that there are blocks which have not been linearly replaced, linear replacement is not performed when real time data is recorded. Thus, real time data can be recorded and reproduced.

  • Publication number: 20040000883
    Abstract: The dual current-limiting circuit for dc brushless motor includes an over-current detective circuit, an operation detective circuit, and a current-limiting circuit. The over-current detective circuit produces a voltage signal being used to determine whether the motor has been input over current. The operation detective circuit also produces a voltage signal being used to determine whether the motor is operated in normal. The current-limiting circuit decides to turn on a first switch of a first current-limiting circuit and to subsequently turn on a second switch of a second current-limiting circuit depending upon the two voltage signals. The current-limiting circuit is capable of suppressing current passing through a coil at low voltage level, which is inadequate to damage a driver circuit and still adequate to restart the motor if the great abnormal input current is eliminated.

  • Patent number: 6671022
    Abstract: A multi-domain liquid crystal display device that is capable of forming a multi-domain by using a gate line. In the device, a data signal is applied to the data line and a gate signal is applied to gate lines crossing the data lines. Switching devices are arranged at each intersection between the gate lines and the data lines and are connected to the pixel electrodes. Auxiliary electrode lines are extended vertically from the gate lines to control an orientation of the liquid crystal with the gate lines. Accordingly, the gate line is used as the auxiliary electrode line, so that an aperture ratio can be improved. Also, a resistance component is reduced, so that problems of the brightness non-uniformity and the generation of a flicker and a residual image, etc. caused by a voltage deviation can be overcome.

  • Patent number: 6671238
    Abstract: A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, method and circuit for detecting the wobble address and a recording medium therefor. When addressing physical identification information on a recording medium, which has land and groove tracks in which data can be recorded, using wobbles, a wobble signal obtained by phase modulating address information indicating the physical identification information and a wobble signal having only a carrier are repeatedly alternatively recorded on both walls of either of a groove track and a land track by way of time division multiplexing. Accordingly, land and groove addresses can be detected by the same method, and the land track can be easily discriminated from a groove track by making the sizes of the addresses different in the land and groove tracks.
