A hosel portion (22) has a screw portion (32) formed on an internal surface or external surface thereof and a hosel hole (28). A screw member (10) has a through hole (30) for causing a shaft (6) and an inner member (8) to penetrate therethrough, a screw portion (32) and a downward surface (56). The screw portion (32) of the screw member (10) and a screw portion (26) of the hosel portion (22) are coupled to each other. The inner member (8) has a shaft inserting hole (40) opened on an upper end side thereof, a lower surface (42) which can be engaged with a receiving surface (60), and an upward surface (44). At least a part of the inner member (8) is inserted into the hosel hole (28). The shaft (6) and the shaft inserting hole (40) are fixed to each other through bonding and/or fitting. The shaft (6) and a head (4) are fixed to each other through an engagement of the downward surface (56) and the upward surface (44) and an engagement of the receiving surface (60) and the lower surface (42). In another embodiment, a shaft (6c) and a head (4c) are fixed to each other through an engagement of a downward surface (35c) and an upward surface (44c) and an engagement of a receiving surface (60c) and an engaging side surface (42c).

A golf club head is provided with a recessed part provided on the external side of a head main body, with a weight member formed of a material having a specific gravity greater than that of the head main body and mounted in the recessed part. A first addition member is mounted on the external side of the weight member in an abutting relationship, with a base of the addition member being a resin or a rubber. The head has a second addition member formed of metal is mounted on the external side of the first addition member in an abutting relationship. The metal of the second addition member has a specific gravity greater than that of the first addition member and smaller than that of the weight member. Through this arrangement, joint strength between the head main body and the weight member is enhanced.

In an apparatus for managing area data, the first data structure for area management includes: a first index data structure including a first root node corresponding to a first set of areas containing a first area, first non-leaf nodes, and first leaf nodes; and a first data storage corresponding to the first leaf nodes. The second storage for area data stores one or more second data structures for area management constructed on the basis of area data collected from data in the first storage for area data based on one or more area attributes designated by a user. The second data structure for area management includes: a second index data structure including a second root node corresponding to a second set of areas containing second areas collected based on the one or more area attributes designated, second non-leaf nodes, and second leaf nodes; and a second data storage corresponding to the second leaf nodes. The storage for data associated with an area stores data associated with an area corresponding to the first areas and the second areas. The storage for region data stores a data structure for region management that is constructed on the basis of a node associated with a region which contains at least one or more of the first sets of areas. The data structure for region management includes a data structure in which at least one node for identifying the region links to either the first root node or the second root node.
摘要:
In a direct conversion receiver, to cancel a DC offset generated in the baseband processing block, negative feedback arrangements comprising a gain control amplifier and a low-pass filter are respectively attached to the I and Q signal branches of the baseband block following mixer outputs. The gain control amplifier in each negative feedback circuit is gain adjusted so that the product G·B of the gain G of a primary gain control amplifier and its own gain B will be constant and thereby the DC offset is cancelled. This DC offset cancellation can be applied in a continuous receiving system with no intermittent time during a receiving operation. Capacitance elements located off-chip can be reduced to those to be used only in the low-pass filters in the negative feedback circuits, whereas many off-chip capacitance elements have been required to be inserted between each stage of gain control amplifiers in conventional baseband chains.

A search method responds to (1) a data base that stores elements (e.g., stores, programs, etc.) that are information search targets, and (2) affiliations among the elements, such as stores that sponsor programs, stores that participate in the programs, etc. Users designate the attributes (stores, programs, etc.) of elements to be searched for, and the affiliations thereof to perform searches, so that the users can easily search for desired information present on small display screens.
摘要:
There is provided a watchband connected to a watch main body. The watchband has a first block, a second block, a connecting pin, an end piece, and a fixing pin. The first block has a first bridge with a first pinhole, and a clamping member disposed in the first pinhole. The second block has a holder that is disposed parallel to the first bridge and has a blind hole, and a second bridge having a second pinhole. The connecting pin extends from the blind hole to the first pinhole and is held with a specific clamping force by the clamping member. The end piece is disposed parallel to the second bridge and is adjacent to the watch main body. The fixing pin extends from the second pinhole to the end piece and connects the second block with the end piece.
