  • Publication number: 20060077789
    Abstract: In a lens holding member for holding a solid immersion lens, when a difference-in-level portion and/or slant face is constructed at least on a part of the objective side surface, a tilt margin which can be applied to a near field optical recording and reproduction solid immersion lens can be maintained. In a focusing lens using such lens holding member, the optical pickup apparatus and the optical recording and reproducing apparatus, stable transportation between the lens and the optical recording medium can be improved.

  • Patent number: 6836433
    Abstract: A rewrite disable control method for a non-volatile semiconductor storage device is disclosed for relying on a majority decision to determine whether a rewrite is disabled or enabled. A write disable control signal generating circuit reads three write disable flags of the same contents stored in security flag storage areas of three memory blocks, respectively, and makes a majority decision to determine a disable/enable state to establish the logic of a write disable control signal. Even if a power supply is instantaneously interrupted during an erasure of a certain block to cause a change in the security flag associated with one memory block, the security flags stored in the two remaining memory blocks maintain the original values, thereby making it possible to effectively prevent a trouble in which an unintended disable setting is validated.

  • Publication number: 20040243878
    Abstract: To provide a microcomputer which is improved to enable the functional selection of a functional macro and the characteristic correction without the mask option, trimming, and dedicated terminal and to quickly start the execution of the microcomputer. The microcomputer includes a main clock signal generating circuit and a ring oscillating circuit which generates a sub-clock signal that quickly enters a stable state. Initialized data is read from a flash ROM synchronously with the sub-clock signal, the read data is stored in a set data register, and a functional macro for the functional selection and characteristic correction is initialized. It is possible to end the setting of the functional macro for a clock stabilizing time necessary for the main clock signal. Further, it is possible to quickly execute the program by switching the signal to the main clock signal just after the clock stabilizing time.

  • Publication number: 20040010403
    Abstract: Rearing simulation game apparatus for a virtual living thing (VLT), as an interactive electronic game with categories of a VLT at every rearing stage increased to variegate game development. A state parameter processor A increases and decreases a “care” parameter representative of a degree of “care” in response to completeness of an operation responsive to a player request, and calculates a “metamorphosis” parameter based on the “care” parameter. Rearing stage processor D selects one category out of a plurality of categories of the VLT lodged in the succeeding rearing stage in accordance with the metamorphosis requirements depending on the “metamorphosis” parameter calculated and the metamorphosis reference value set peculiarly to the “category” of the VLT in the present rearing stage.
