A method is provided of retrieving one or more data items stored in a protected area of a remote server for transferral to a local device. A trusted connection is formed between an information device and the protected area of the remote server. The information device and the trusted connection are employed to select a first group of one or more data items stored in the protected area of the remote server. The first group of data items are transferred from the protected area to a holding area outside the protected area of the remote server. A retrieval connection is formed between the local device and the holding area. A second group of one or more data items is determined from the first group of data items transferred to the holding area. The second group of data items is transferred from the holding area to the local device over the retrieval connection.

Disclosed is a linear guide device in which a rate of change expressed as “Dmax−Dmin”, becomes extremely small where Dmax and Dmin are respectively a local maximum and a local minimum of D, expressed as (dx2−dx1)/dx, which is produced when a steel ball B moves a distance corresponding to a rolling element-to-rolling element span, dx1 is a minute movement quantity of a steel ball B when it moves from one space defined between rolling element rolling grooves 3 and 31 of an element endless circulating raceway 7, to one of curved element circulating R parts 6, and dx2 is a minute movement quantity of another steel ball B when it moves from the other curved element circulating R part 6 to the space while the former steel ball is moved by the minute movement quantity dx1.

In a retaining piece interposed between the adjacent rolling balls, a concave surface of each of both side surfaces of the retaining piece where it contacts with the spherical surfaces of the balls is configured to partly contact with the spherical surface of the ball. The concave surface includes a linear contact portion to be in contact with the ball and an approximate curved surface having the radius of curvature approximate to that of the ball, which is located on the inner side of the linear contact portion. In addition, recesses which are joined to the gate portion and the ejector pin in a molding process are formed in the concave surfaces. A recess is formed at the joining portion or near a parting line. Fins formed in the molding process are capable to be put into the recess.

When the unevenness quantities of the surface of a surface-treated, existing concrete are measured at a given pitch by a measuring device 10, the measured unevenness quantities are automatically collected by a CPU 21 to calculate the characteristic quantities of the surface-treated form of the existing concrete. The CPU 21 compares the calculated characteristic quantities with characteristic quantities beforehand stored in a data ROM 23 to give an evaluated result of the surface-treated form automatically. The evaluated result is displayed on a display device 40 or printed by a printer 50, so that the result can be immediately checked. An ideal surface-treated form is a surface-treated form in which the average height of unevenness of the surface of the existing concrete is from 13 to 35% of the maximum particle size of aggregates contained in the existing concrete, and the slope length ratio thereof is 1.13 or more, and the unevenness having a height of 2 mm or more occupies 14% or more of all the unevenness.

Semiconductor circuit of MOS transistors for generation of the desired reference voltage over a wide range with almost no dependence on the power voltage. An enhancement type MOS transistor and 1st depression type MOS transistor are connected in series across the power voltage, and a 2nd depression type MOS transistor and resistance component connected are in series across the power voltage. The above 1st depression type MOS transistor is connected to the gate of the 2nd depression type MOS transistor, and the reference voltage is derived from the connection point of the 2nd depression type MOS transistor and the resistance component.

A linear guide apparatus maintaining a high dust-proof performance over an extended period of time and includes side seal units attached to end parts of a slider in the axial direction. Each side seal unit is provided with: a first seal member, at the slider, arranged in the axial direction of the slider; a second seal member at the outside of the slider in the axial direction; and a lubricating member held between the first and second seal members. The first seal member has first lip parts sliding against the rolling element rolling grooves of the guide rail, while the second seal member has second lip parts sliding against the rolling element rolling grooves. The lubricating member has a first oil-containing member for supplying lubricant to the rolling element rolling grooves. The first and second lip parts are arranged not to come into contact with the first oil-containing member.
