Abstract:
PROBLEM TO BE SOLVED: To provide a radio communication apparatus and a response data processing method for the radio communication apparatus for individually performing response data processing even without being controlled by a control means. SOLUTION: The radio communication apparatus that is provided with the control means, requests response data to an external wireless device and waits for the response data is further provided with a radio communication interface device including: a timer measuring means that measures a time limit for waiting for the response data from the external wireless device; a receiving means that receives first response data from the external wireless device and then immediately receives second response data without an instruction from the control means; a frame length confirming means that confirms the frame length of the received response data; and an error detecting means that stores at least the response data while performing error detection on the response data and stores the result of the error detection for the response data. The radio communication interface device performs alone the error detection and stores the response data while receiving at least the response data from the external wireless device singly without being controlled by the control means.

PROBLEM TO BE SOLVED: To provide an exposing method and an exposing device unnecessitating the exchange/ readjustment of an exclusive machine and an optical system device and to provide an original disk and an optical disk of high definition by using them. SOLUTION: In this method, a light attenuating means (variable light shielding unit 2) for attenuating an emitted light beam from a laser beam source 1 and a light splitting means (splitter 3) for splitting the emitted light beam into two beams are arranged, one light beam splitted by the light splitting means is made incident on a light quantity detecting means (light quantity detector 5), the light quantity is measured, a signal based on the light quantity is supplied to the light attenuating means from the light quantity detecting means, the light quantity of the emitted light beam transmitted through the light attenuating means is controlled and a photoresist film formed on an original disk is irradiated/exposed with a converged light spot of the other beam splitted by the light splitting means by using an objective lens 8. In this case, a light quantity incident on the light quantity detecting means is made almost constant by means of a light quantity limiting means (ND filter changeover device 4) arranged on the optical axis between the light splitting means and the light quantity detecting means and composed of an ND filter 10, etc., capable of selecting insertion and withdrawal.

PROBLEM TO BE SOLVED: To extend a movable range against a direction offset by a forming unit by installing the forming unit on another forming unit so that it rotates around a position offset from a central axis of the other forming unit as its center. SOLUTION: A neck part unit 11 is installed on a thigh part unit 24 by devising it to be supported by a second axis 14 held by projection parts 24AX, 24BX between each of the projection parts 24AX, 24BX of a right side surface 24A and a left side surface 24B of the thigh part unit 24 free to rotate. Consequently, on a robot, the neck part unit 11 of each of leg parts 25A-25D is devised to rotate around a position offset in the front direction from a central axis K1 of the thigh part unit 24 (that is a position of the second axis 14) as its center.
Abstract:
PROBLEM TO BE SOLVED: To prevent two or more communication partners from replying simultaneously. SOLUTION: An NFC communication device 1 transmits data requesting IDs, and acquires IDs transmitted by NFC communication devices 2 and 3 in response to the request. After acquiring the IDs of the NFC communication devices 2 and 3, the NFC communication device 1 transmits data including the IDs of the NFC communication devices 2 and 3 as data for them. If the NFC communication device 1 cannot normally acquire the IDs of the NFC communication devices 2 and 3, the NFC communication device 1 transmits the data requesting the IDs again. When receiving the request for the IDs, the NFC communication devices 2 and 3 generate their own IDs by random numbers to transmit them. When receiving the request for the IDs again, the NFC communication devices 2 and 3 regenerate their own IDs by random numbers to transmit them again. This invention is applicable to an IC card system, for instance. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To enable to easily perform communications between a plurality of wired communication modules connected to a communication apparatus and an external wireless communication apparatus and between the wired communication modules. SOLUTION: A wireless communication interface module 12 transmits signals from the wired communication modules 3-1 through 3-3 which are output from an input signal compositing selecting section 13 to a radio communication apparatus 2 via an antenna 11. A wired signal output section 14 outputs signals from the wireless communication apparatus 2 which are output from the selecting section 13 or signals from the wired communication modules 3-1 through 3-3 to all the wired communication modules 3-1 through 3-3. This apparatus and method are applicable to a communication apparatus for performing short-range communication. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To prevent responses from being simultaneously returned from two or more communicating parties. SOLUTION: An NFC communication apparatus 1 transmits data that request an ID, and acquires IDs which are transmitted by NFC communication apparatuses 2 and 3 in response to the request. The NFC communication apparatus 1 acquires the IDs of the NFC communication apparatuses 2 and 3 and then transmit data including the IDs as data for the NFC communication apparatuses 2 and 3. When the NFC communication apparatus 1 can not normally acquire the IDs of the NFC communication apparatuses 2 and 3, on the other hand, the NFC communication apparatus 1 retransmits the data requesting the ID. When the NFC communication apparatuses 2 and 3 receive the request of the ID, the NFC communication apparatuses 2 and 3 generate their own IDs by means of random numbers and transmit the IDs. Furthermore, when the NFC communication apparatuses 2 and 3 receive the request of the ID again, the NFC communication apparatuses 2 and 3 generate their own IDs by means of random numbers again and retransmit the IDs. The present invention can be applied to an IC card system, for example. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To realize various types of near-field communication according to needs. SOLUTION: In a near-field communication method, when an RF field is not detected within a predetermined time T IDT +n×T RFW , an NFC communication apparatus 1 being an initiator, starts outputting electromagnetic waves, activates an NFC communication apparatus 2 being a target, and transmits a request via a first electromagnetic wave resulting from modulating electromagnetic waves by means of transmission data. When communication of an active mode is started and the RF field is not detected within a predetermined time T ADT +n×T RFW , the NFC communication apparatus 2 starts outputting electromagnetic waves, and transmits a response to the request via a second electromagnetic wave resulting from modulating electromagnetic wave by means of transmission data. When communication of a passive mode is started, the NFC communication apparatus 2 transmits a response to the request by applying load modulation to the electromagnetic wave from the initiator. The near-field communication method can be applied to, for example, an IC card system. COPYRIGHT: (C)2005,JPO&NCIPI
