Title: Parallel stranded conductor
Inventor: AOKI TADAHISA
IPC: H01H71/08
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To minimize the bundle width to contract the case width of an electric apparatus and to improve the performance of the electric apparatus by comprising stranded conductors different in length, and bending them in U-shape with a larger diameter as the stranded wires are longer. SOLUTION: A plurality of stranded conductors 1A, 1B with the same thickness and different length are connected in parallel, and both the ends are bonded by caulking parts 2. Since the stranded conductor 1B is longer than the stranded conductor 1A, the stranded conductor 1B is formed in U-shape with a radius larger than in the stranded conductor 1B, whereby it is not required to arrange the stranded conductors 1A, 1B in the direction right-angled to the plane formed in U-shape or the lateral direction in the bundling of the stranded conductors 1A, 1B. Thus, the bundle width corresponds to the width X of one stranded conductor 1A, and the stranded conductors 1A, 1B can be bundled in a small width. Even if the thicknesses of the stranded conductors 1A, 1B are mutually differed, the bundle width is equal to the diameter of the thicker stranded conductor.  In each case, the bundle width is smaller than that of a conventional 2-parallel stranded conductor.

Title: Driving mechanism having electromechanical transducing element
Inventor: MIYAZAWA MASAYUKI
IPC: H02N2/00
Filed: 1996-01-04
Abstract: PROBLEM TO BE SOLVED: To provide a driving mechanism having an electromechanical transducing element capable of preventing the generation of impulsive sounds and resonance sounds by controlling a driving speed. SOLUTION: An ON/OFF control signal is outputted from a PWM circuit 12 to a constant current circuit 14 and an FET 15 by a duty ratio determined by a CPU 11. The output of a booster circuit 13 charges piezoelectric elements 21 slowly through the constant current circuit 14, and the charges of the piezoelectric elements 21 are discharged quickly when the FET 15 is turned on. A drive shaft 22 united and fixed to the piezoelectric elements 21 generates expansion/contraction displacement vibration of different speeds, and it is possible to move a lens holding frame 23 friction-united to the drive shaft. At the time of a driving start, charges to be charged in the piezoelectric element 20 are controlled increasing the duty ratio gradually from zero, and the quantity of expansion and contraction of the piezoelectric elements 21 is controlled.  Consequently, it becomes possible to perform driving at a low speed at the time of the driving start, and to raise the speed gradually.

Title: Method for coupling processor
Inventor: IWASAKI KAZUHIKO
IPC: G06F15/173
Filed: 1989-01-24
Abstract: PURPOSE:To eliminate restriction to the number of IC chips to be mutually connected and to reduce a maximum distance between the IC chips by obtaining logical coupling between plural processors by jump coupling in the positive and negative directions of x and y axes in addition to two-dimensional grating coupling. CONSTITUTION:An IC chip (1,0) is connected to (1,0), (7,0) in the x axis direction and (0,1), (0,7) in the y axis direction as the two-dimensional grating coupling. Simultaneously, the IC chip (1,0) is also connected to (3,0), (5,0) in the x axis direction and (0,3), (0,5) in the y axis direction as the jump coupling. An IC chip (3,4) e.g. is connected to (4,4), (2,4) in the x axis direction and (3,7), (3,1) in the y axis direction as the two-dimensional grating coupling. Since the logical coupling between plural processors can be obtained by the jump coupling in the positive and negative directions of both the x and y axes in addition to the two-dimensional grating coupling, the maximum distance between the IC chips can be reduced without restricting the number of IC chips to be mutually connected.

Filed: 1993-01-06
Abstract: PURPOSE:To prevent damage on a sample by providing a deflection means for deflecting an electron bean on the first optical axis to the second optical axis, so that a negative ion emitted with the electron beam from an electron source is surely trapped at the time of applying superhigh acceleration voltage. CONSTITUTION:When deflection system 3, 4 are energized, a negative ion 19 and an electron beam 20, going out from an acceleration tube 2, are projected into a deflecting magnetic field generated by the upper part polariscope 3, but since mass of the negative ion 19 is large as compared with the electron beam 20, the negative ion is not deflected by an electron beam deflection magnetic field but advances straight to arrive at a Faraday cup 9. Here in an ammeter 11, a current value of only the negative ion 19 can be detected. On the other hand, the electron beam 20 deflected in the upper part deflector 3 is deflected by the lower part deflector 4 by the equivalent amount in a reverse direction in a deflecting direction by the upper part deflector 3, and an axis of the beam is aligned to an electronic optical lens system optical axis Y2 in parallel to an optical axis Y1. By this 2-step deflecting operation, the negative ion 19 is not contained in the electron beam 20 incident upon a convergent lens 12.

IPC: G01C19/00
Filed: 1986-01-29
Abstract: PURPOSE:To obtain a gyroscope which is superior in reliability and environmental condition by measuring magnetic flux produced by the rotary component of a superconductor which forms a closed loop. CONSTITUTION:A pickup coil 2 for magnetic flux is provided in parallel to the loop 1 of the doughnut-shaped superconductor 1, and the coil 2 is connected to a squid fluxmeter 3. The whole device is fitted to a support body 4 and cooled while shielded magnetically to cause superconduction transition. In a starting state in which the superconductor is cooled, quantities are not changed by the subsequent motion of the superconductor. For example, when it is assumed that there is no magnetic flux phipenetrating the loop 1 in the starting state and this superconductor is placed in a system rotating slowly (at angular speed OMEGA), magnetic flux phi is generated eventually. The magnetic flux phi is measured by a fluxmeter 3 to know the angular speed OMEGA. Therefore, when the output of the fluxmeter 3 at the point of time of cooling is considered to be in the initial state, the output indicates an increase or decrease from the initial magnetic flux value according to the component of rotary motion during the subsequent motion of the system along with the whole device. It is read and data processing is carried out to know the change in direction from the starting point.
