Abstract: PURPOSE:To reduce the cost over the entire part by forming a magneto-optical recording material layer to a specific thickness and setting the ratio of the magnetic permeability of an underlying layer and the magnetic permeability of the magneto-optical recording material layer to a specific range. CONSTITUTION:This target is formed of the two-layered structure consisting of the underlying layer 1 exposed with the underlying layer 1 on the surface on the side facing magnetic poles M1 to M3 and exposed with the magneto-optical recording material layer 2 consisting of a ferromagnetic material on the surface on the opposite side, respectively, and the magneto-optical recording material layer 2. The thickness (d) of the magneto-optical recording material layer 2 is changed in the plane direction of the planar target. Namely, the magneto-optical recording material layer 2 is so formed that the thickness d1 in the part facing the magnetic poles M1 to M3 of the target is smaller than the thickness d2 of the parts exclusive thereof. The ratio of the magnetic permeability mu1 of the underlying layer 1 and the magnetic permeability mu2 of the magneto-optical recording material layer 2 is set in the range of inequality. The efficiency of using the costly magneto-optical recording material layer is then enhanced by controlling an erosion profile. The cost over the entire part of the target is reduced in this way.

Abstract: PURPOSE: To obtain an acceleration sensor whose reliability is excellent and which is constituted at low costs. CONSTITUTION: In an acceleration sensor, both plate faces of a mass body 12 supported by a frame body 11 via a hinge 13 and stoppers 18, 19 which are faced via respective prescribed gaps are bonded to both plate faces of the frame body 11. In the acceleration sensor, a ventilation hole 31 is formed in the stopper 19 situated on the side of a plate face opposite to a plate face on which terminals 17a to 17d at the frame body 11 have been installed. When the stoppers 18, 19 are bonded at a high temperature, a pressure in an internal space 23 is not raised, and they can be bonded satisfactorily without causing any dislocation. In addition, when a wafer is cut, the ventilation hole 31 is lidded with a wafer sheet 27.  As a result, even when the ventilation hole 31 is not sealed airtightly with an adhesive or the like, it is possible to prevent a cutting liquid from creeping into the internal space 23.

Title: Clamping device for cutting machine
Inventor: FUSEGAWA NOBUMASA
IPC: B23D47/04
Filed: 1987-05-26
Abstract: PURPOSE:To correct a position of diagonally feeding a long-sized material and to prevent a disc grinding wheel from being damaged, by forming one of the hydraulic cylinders to position its connection position farther distant than the similar connection position of the other from arm mounting shafts serving as the supporting points, of the pair of right and left clamping arms. CONSTITUTION:A hot processed column-shaped long-sized steel material is conveyed onto a cutting supporting bed 16 being clamped by hydraulic cylinders 3, 4 between clamping parts 9, 10 of clamping arms 1, 2. Here a clamping device, which forms a distance between a connection position 7 of the cylinder 3 in the arm 1 and an arm mounting shaft 5 larger than the distance between a connection position 8 of the cylinder 4 in the arm 2 and an arm mounting shaft 6, increases pressing force of the one arm 1 larger than that of the other arm even if the cylinders 3, 4 generate equal power. Accordingly, the hydraulic cylinder operates fully to its power playing a role as the stopper for a workpiece, and the long-sized material, even when it is diagonally conveyed, is clamped being corrected to a straight condition. Next the material is cut by a disc-shaped grinding wheel 18, but the device, preventing a cut part from moving just before completion of cutting, causes the disc-shaped grinding wheel to generate no damage at all.

Filed: 1994-05-17
Abstract: PURPOSE:To provide an image reader capable of reading a large original by one time of operation and without requiring a complicated processing circuit for the processing of reading data by providing specific feed means and read head. CONSTITUTION:Original feed rollers 7a, 7b, 8a and 8b driven and rotated by a motor 6 for original feed are provided oppositely to the original 1 inserted from a paper supply port 4a, and the original 1 is fed along a feed path by the rotation of the rollers 7a, 7b, 8a and 8b. Since the paper supply port 4a is formed bent nearly in a U-shape, feed width in a horizontal direction can be reduced by bending the original 1 on a plane at right angles to a feed direction. Therefore, it is possible to read the image of the large original 1 even when the whole device is miniaturized so as to be transported by one time of feed operation and to perform the processing of image information as it is by a host computer by using the read data.

Title: Pile, method for pile-jacking pulling-out construction and pile jacking pulling-out machine
Inventor: KITAMURA MORIO
IPC: E02D5/30
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To miniaturize and lighten a clamp, to narrow a working range, to shorten a moving time by self-advancing and to posture an attitude at the time of movement. SOLUTION: Sections to be held 11 formed in a plate shape thinner than pile bodies 12 and held by clamps 21... for a pile jacking pulling-out machine 20 are installed to the upper sections of the U-shaped sectional pile bodies 12. When the machine 20 is moved on continuous piles 10, the clamps 21 need not be opened largely for releasing holding because there is no irregularity in the side faces of the sections to be held 11. Consequently, the clamps 21 are miniaturized and lightened. The working range of the pile jacking/pulling-out machine 20 is narrowed by miniaturizing the clamps 21. Since the clamps 21 need not be opened largely at the time of movement, the operating time of the clamps 21 is shortened, and the moving time of the pile jacking/pulling-out machine 20 can be shortened.  An attitude can be stabilized by mounting wheels rolled on the top faces of the sections to be held 11 on the machine 20.

Abstract: PURPOSE:To remove both inter-code interference and phase fluctuation even under an environment using RLS algorithm by applying a phase circuit to the input of a complex transversal filter and supplying the result of applying phase rotation to a tap coefficient control part. CONSTITUTION:For the output of a judgement equipment 19 to judge and output transmitting data, a multiplier 21 executes complex multiplication with the output of a complex conjugate part 22, and the phase rotation is applied corresponding to the amount of the phase fluctuation. The output is turned to the input of a rear filter formed by a shift register 151 and a multiplier 152, and the output of the rear filter is supplied to a tap coefficient control part 18. Thus, even when high convergent speed algorithm such as the RLS algorithm is used for the control part 18, a tap coefficient is updated by the same process regardless of whether the phase fluctuation exists or not, and both the inter-code interference and the phase fluctuation can be removed even under the environment of the RLS algorithm.
