A positioning signal from a satellite positioning system is received at a mobile station, correction information from a reference station is used, a pseudo distance observation formula using a code and a phase distance observation formula using a carrier wave are used to perform positioning using single frequency at the mobile station, and these observation formulas are expressed by a satellite clock error, clock errors at the reference station and the mobile station, a ionospheric delay and a tropospheric delay, and a code bias and a phase bias of single frequency at the reference station, the mobile station and a satellite.

There is provided a driving devicein which an electromechanical transducer is used and which has a high drive efficiency, having an electromechanical transducerthat is extended and contracted by application thereto of voltages, a drive shafthaving one end fixed by adhesiveto the electromechanical transducer, and a movable memberthat is frictionally engaged on the driving shaft, an expression 8&#x2267;E/t&#x2267;0.48 where t (&#x3bc;m) is a thickness of the adhesive and E (GPa) is a modulus of longitudinal elasticity of the adhesive is satisfied by mixing into the adhesiveparticulatesthat have diameters not smaller than 1 &#x3bc;m and not larger than 5 &#x3bc;m.

Driving device

A driving device includes an electromechanical transducer that is extended and contracted by application of voltage, and a support member that slidably supports a movable body and that is displaced together with the electromechanical transducer to which the support member is connected, the movable body being driven along the support member with the extension and contraction of the electromechanical transducer. The movable body has a main element, a pinch member that is assembled on the main element so as to pinch and hold the support member, and a biasing member that biases the pinch member toward the support member. A part of the pinch member abuts on the support member and other part thereof is held on the main element in a cross section perpendicular to a movement direction of the movable body when the pinch member is biased by the biasing member.

To provide a three-dimensional molding technique capable of generating a three-dimensional molded article in short time. In a three-dimensional molding apparatus, a powder material is allowed to drop via an opening while moving a thin layer formation section in the +X direction, thereby forming a powder layer on a molding stage. With respect to a selected region in the powder layer, a binder of ultraviolet-ray hardening resin is discharged from a head section. Then, the powder layer is irradiated with ultraviolet rays from an ultraviolet irradiation section, making the ultraviolet-ray hardening resin applied on the powder layer harden to thereby bind the powder material. By repeating this operation with respect to the powder layer which is sequentially formed, a three-dimensional molded article is formed. In this way, since an ultraviolet-ray hardening resin is used as a binder and a powder material can be bound rapidly by ultraviolet irradiation, it is possible to generate a three-dimensional molded article in short time.
