摘要:
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.

A robot toy includes a body and a controller. The body includes right and left arms, legs, arm-actuating mechanisms, thrust mechanisms, and a driving unit. The arms can be extended forward and back, and are pulled back by a predetermined biasing force in a normal condition. The arm-actuating mechanisms provided at the respective arms allow the corresponding arms to be extended in front of the body against the biasing force. The thrust mechanisms provided at the respective legs allow the corresponding legs to move forward. The driving unit drives one of a pair of the left arm-actuating mechanism and the left thrust mechanism and a pair of the right arm-actuating mechanism and the right thrust mechanism. The driving unit simultaneously drives the arm-actuating mechanism and the thrust mechanism in the same pair.

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.

In the present linear guide bearing, the center of curvature O′ of a ball reversing passage 27 is shifted to a return side ball passage 25 side by a given amount m when compared with the center of curvature O′ of a conventional guide bearing. Due to this, not only the radius of curvature of a concave-arc-shaped groove 29 formed in each end cap 9 is reduced by a given amount m but also the concave-arc-shaped groove 29 is shifted to the return side ball passage 25 side by a given amount m, when compared with the conventional guide bearing. Thus, an angle &agr; formed between a line connecting the leading end of a tongue portion 31 to the center of curvature O′ of a ball reversing passage 27 and the moving-direction end face of a bearing main body 7, can be reduced significantly when compared with the conventional bearing.

A weighing apparatus has a weighing conveyor with a conveyor belt driven by a drive motor for transporting and weighing an object at the same time and outputting a weight signal indicative of its weight. The lengths of the weighing conveyor and the object in the direction of transportation are inputted and the weight signals outputted by the weighing conveyor are filtered so as to eliminate vibration components due to the vibration of the conveyor. The distance traveled by the object on the weighing conveyor is detected from the angle of rotation of the drive motor, and the timing for processing the weight signals, or when to start the measurement of weight and when to obtain the weight value, is determined independent of the transportation speed of the belt but from the detected distance traveled by the object and the inputted length values.

In a linear guide bearing apparatus wherein a separator is interposed between adjacent balls K and K moving following a curved circulating path 8, and the ball K contacts concave faces W of the separator Tat both ends in an axial line direction and at the same time the ball K rolls as contacting a guide face 8a of an outside guiding member 5 and a guide face 8b of an inside guiding member 9, the separator has an outer diameter larger than a maximum outer diameter LØ under a condition where the ball rolls as simultaneously contacting both curved faces 8a, 8b of the inside and the outside of the curved circulating path 8, and the radius of curvature of the guiding face 8b in the curved circulating path 8 is reduced to a size not contacting the separator T.

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.
