Title: Micro motion device and moving method employing piezoelectric element producing impact force
Inventor: HIGUCHI TOSHIRO
IPC: B23Q5/50
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a micro motion device employing piezoelectric elements producing impact force by applying sine wave voltages, having a phase difference, onto first and second piezoelectric elements fixed, respectively, in the vertical and horizontal directions of a mover. CONSTITUTION:A sine wave voltage Va is applied onto a first piezoelectric element 7 whereas a sine wave voltage Vb having phase difference is applied onto a second piezoelectric element 9. Consequently, the first piezoelectric element 7 elongates to press a mover 6 against the frictional surface of a base 5 thus increasing the frictional force. Under that state, the second piezoelectric element 9 contracts and the mover 6 scarcely moves. Subsequently, the first piezoelectric element 7 contracts to decrease friction of the mover 6. Under that state, the second piezoelectric element 6 elongates to move the mover 6 smoothly rightward by a single pitch with an impact force.

Title: Slot antenna for twisted pair type leakage cable
Inventor: YAMANAKA MICHIO
IPC: H01Q13/22
Filed: 1987-12-25
Abstract: PURPOSE:To control the radiation strength of a cross polarized component and to improve the directivity of the antenna with respect to a major polarized wave as a whole by forming an H-shaped slot on a conductor face, setting feeding points energized through a balanced-unbalanced conversion circuit to symmetrical positions in the center of the slot. CONSTITUTION:The H-type slot 2 is formed to the conductor face 1 and the feeding points 41, 42 energized through the balanced-unbalanced conversion circuit are set to symmetrical positions in the center of the H-shaped slot 2. In case of energizing the antenna from the feeding points 41, 42 and of radiating a radio wave through a basic radiation slot 21, the major polarized wave radiated from the center is preserved as it is, but electric field components E2-E5 of the cross polarized wave radiated from remaining branch slots 22-25 of the basic radiation slot 21 are canceled together and it is equivalent externally that no radiation is caused from the antenna. Thus, only the major polarized wave is radiated as a whole with a sharp directivity and then the excellent directivity is obtained.

Abstract: PROBLEM TO BE SOLVED: To manufacture a high performance liquid crystal display having a number of scanning lines, being able to fulfil requirements of low voltage driving, a wide temperature range quick response. SOLUTION: The liquid crystal optical element utilizes a liquid crystal composition having at least two domains with respective different electrooptical characteristics. V1>0 holds with respect to an applied voltage V1 for minimum transmissivity in electrooptical response in a domain 1 and V2<0 holds with respect to an applied voltage V2 for minimum trnasmissivity in a domain 2. Furthermore, shapes of voltage-transmissivity curves of the domain 1 and the domain 2 are mutually almost symmetrical with an axis of symmetry at 0 applied voltage. Besides in the case the domain 1 and the domain 2 coexist in the same pixel, the electrooptical characteristic of the pixel is an intermediate one between these characteristics of the domain 1 and the domain 2.  Consequently if 0<A1/(A1+A2)<1 holds, assuming areas of the domain 1 and the domain 2 in a pixel as A1 and A2 respectively, a V-shaped characteristic curve is exhibited.
