A slice set for a specific period of time is acquired from a storage area of a memory which is a ring buffer while changing the read position, and the signal strength total value of each slice set is calculated. The signal strengths of the slices included in the maximum strength slice set and the signal strengths of the slices preceding or subsequent to the maximum strength slice set are calculated, and the final signal read position is determined based on a read offset of the maximum strength slice. A GPS satellite signal is acquired and tracked based on the slice read from the determined signal read position, and a specific positioning process is performed.

In a multi-piece solid golf ball having a core, an envelope layer, an intermediate layer and a cover, the hardness profile at the core interior and the hardness relationships among the various layers are optimized. The ball is endowed with an excellent flight performance on shots with a driver and an excellent controllability in the short game that are acceptable to professionals and other skilled golfers. The ball also has a good feel at impact and an excellent scuff resistance.

Electronic equipment includes a GPS dongle for acquiring current location position information, and a PC for acquiring planned installation position information indicating a planned installation position of a machine tool previously registered with a server device which is a supplier-side device of the machine tool from the server device. The electronic equipment compares the acquired current location position information with the acquired planned installation position information, to determine whether or not the current location is within a predetermined range having the previously registered planned installation position as a base point. The electronic equipment determines, if it is determined that the current location is within the predetermined range having the planned installation position as a base point, whether or not a predetermined condition has been satisfied. The electronic equipment performs, if it is determined that the predetermined condition has been satisfied, information input processing on the machine tool, to remove activation restriction on the machine tool. In this manner, the electronic component can prevent illegal removal of activation restriction on the machine tool.

The invention provides a golf ball having a core formed by vulcanizing a rubber composition and a cover composed primarily of a polyurethane material. The rubber composition of the core includes 100 parts by weight of a base rubber, from 10 to 40 parts by weight of an unsaturated carboxylic acid or a metal salt thereof, a peroxyketal (a) and a monophenol-type antioxidant (b), the weight ratio (a)/(b) of the peroxyketal to the monophenol-type antioxidant being from 5 to 50. The ball has an excellent discoloration resistance and an outstanding distance and feel on shots taken with a middle iron.

A positioning method includes (a) adding cumulatively each of an I component and a Q component of a received signal of a positioning signal per polarity, the positioning signal being spread-modulated with a spread code reversed in polarity by a navigation data, (b) calculating sum of squares of the results of the cumulative addition in step (a), (c) executing correlation calculation of the sum of squares calculated in step (b) with a replica code of the spread code, and (d) executing predetermined positioning calculation based on the result of the correlation calculation in step (c) to perform positioning of the present location.

A multi-piece solid golf ball has a core, at least one intermediate layer encasing the core, and a cover of at least one layer encasing the intermediate layer. The core is formed of a base rubber, and the intermediate layer and cover are each formed of a resin material. The intermediate layer has a thickness (a) and the cover has a thickness (b) such that the ratio a/b is from 0.7 to 1.9, and the core has a diameter (c) such that the ratio c/a with the intermediate layer thickness (a) is from 23 to 38. The intermediate layer has a material hardness (Shore D) of from 54 to 76, and the cover has a material hardness (Shore D) of from 47 to 69. The ball satisfies the following relationship: cover material hardness core surface hardness. This golf ball has an improved flight performance and a good, solid feel on impact.
