A method of magnetotelluric exploration is described, wherein measures of the earth's electric and magnetic fields are obtained at a plurality of sensing locations comprising an areal array of sensing locations. Specifically, first and second components of the earth's electric field are measured at a plurality of sensing locations within an areal array of sensing locations whereby each of the components of the earth's electric field are spatially continuous. Additionally, first and second compon...

A charge coupled device comprises: a semiconductor substrate of one conductivity type; a one-dimensional first charge coupled device including a plurality of continuous electrodes arranged in a one-dimensional array on the semiconductor substrate and a channel region formed below each of the electrodes; a second charge coupled device that is continuous to an end of the first charge coupled device and includes two branched portions, each of the two branched portions comprising at least one electr...

A piezoelectrically actuated driving and adjusting apparatus transmits both pure translation movements and rotation movements. The object of the present invention is to provide a piezoelectrically actuated driving and adjusting apparatus having a simple, compact and robust mechanical structure, capable of ensuring long adjustment paths and suitable for various adjustment and drive tasks using the same principle structure. Two parallel stacks of piezoelectric elements are arranged as close as pos...

First and second boosters are attached to a holder in the following manner to prevent a portion between the first and second boosters from being curved. The outer side surface of a projecting portion on the outer peripheral surface of a second booster is pressed toward the inward of the holder by a stopper attached to the holder so that a stepped portion formed in the interior surface of the holder is pressed by the projecting portion through a bridge member and a projecting portion on the outer...

An apparatus according to the present invention includes a support structure having a primary portion with first and second arm portions formed thereon for movement relative to one another, and a secondary portion with either a clamp portion or valve portion integrally formed on an outer end of each arm portion for movement therewith. A primary actuator is operably associated with the primary support structure for driving the arm portions relative to one another in response to an electrical acti...

A dropout file storage drawer is slidably mounted on a bearing track assembly and includes a forwardly positioned cam and follower arrangement which permits the drawer to slope slightly downwardly while it is being pulled out of its associated cabinet. The slope angle continually increases as the drawer is pulled farther out of the cabinet, while a rearwardly positioned stop limits the distance of drawer removal. If desired, the drawer can be moved over the stop so as to permit the drawer to be ...

An electromechanical transducer device includes a casing having a distal end and a proximal end, and an acoustic wave generator disposed inside the casing for generating an acoustic type vibration in response to an electrical signal. The acoustic wave generator having an axis extending between the proximal end and the distal end of the casing. An electrical transmission lead is mounted to the casing and is operatively connected to the acoustic wave generator for transmitting an electrical signal...

In a vibration wave motor disclosed in this specification, at least one straddling member is coupled to a vibration member along the direction of travel of a traveling vibration wave in such a manner as to straddle between two points having a spacing corresponding to (.lambda./2+n.lambda.) (n being an integer including zero), and the straddling member is rotatably coupled to a fixed member at the central position between the two coupling points of the straddling member.

Method of manufacturing a hydrophilic roll in which a hard metal is ground during manufacturing to provide a polished finish, the finish measured to determine the number of peaks and valleys and grinding continued with a finer grinding wheel until the peaks and valleys which exceed 5 micro-inches from a center line for the peaks and valleys are less than ten per inch of length and those which deviate more than 2.5 micro-inch from the center line number less than 100 per inch. The roll is then tr...
