Title: Reed switch
Inventor: YOKOGAWA TOSHIKI
IPC: H01H1/66
Filed: 1988-01-08
Abstract: PURPOSE:To thin a switch by using a thin plate of ferromagnetic substance as a reed piece and providing at least one notch at least at one side in the longitudinal direction of two reed pieces so as to form two reed pieces in the same plane. CONSTITUTION:An external magnetic field is applied almost in parallel with the longitudinal direction of a reed switch. For the direction of the external magnetic field, either of left and right will do and when the external magnetic field is applied to where it is normally closed, magnetic charge appears to a notch 2 and a contact 3, and at the contact it seeks to maintain it when the magnetic force works and it is normally closed. As against it, at the notch 2 the magnetic force works toward the direction to narrow a V letter-shaped bottom angle, and it seeks to bend a reed piece 1a with the vicinity of the notch 2 as the center. Resisting this force, restoring force appears to the reed piece a. When the magnetic force to bend overcomes other force, the switch is released and when the external magnetic field is released from that condition, the contact is normally closed with the restoring force of the reed switch 1a. In this way, the opening and closing of the switch is performed by the bending action inside the plane when the external force is applied, and the switch is made in skin shape.

Title: Liquid crystal display medium and its driving method
Inventor: ASABE YOSHIYUKI
IPC: G09F9/35
Filed: 1995-01-11
Abstract: PURPOSE: To make it possible to easily control the orientation state of liquid crystal molecules after removal of an impressed voltage by forming two sheets of transparent electrode plates of materials exhibiting resistance values varying from each other. CONSTITUTION: ITO films 5 consisting essentially of indium oxide are respectively deposited as transparent electrodes on the inner surface of a pair of glass substrates 4, 4 having a thickness of about 1mm in order to impress voltage on the liquid crystal molecules. The combination of the respective resistors of the ITO electrodes 5 deposited on these two glass substrates 4, 4 consist of the material exhibiting the high resistance value on the thick high-polymer layer side and the material exhibiting the low resistance value on the thin high-polymer layer side. The volumetic resistivity value of the high polymer of such liquid crystal display medium is higher than the resistance value of the nematic liquid crystals and the dielectric constant is low and, therefore, the high polmer plays the role of a capacitor and the intensity of the electric filed is changed by a frequency.  The resistance values of two transparent electrode plates are different with each other and therefore, the polarization of electric field is caused. The easy control of the so-called memory characteristic is made possible by changing the frequency of the impressed voltage.

Abstract: PURPOSE:To detect a charge, a speak discharge etc. in a simple structure without power source by connecting an outgoing line of a coherer to a core wire and the shielding part of a shield wire, and mounting a pickup to a core wire at the other end of said shield wire. CONSTITUTION:An adjusting capacitor 5 is connected between two outgoing lines 4, 4' of a coherer 1. One end of the outgoing line 4 is connected to a core wire 13 of a shield wire 6 and the outgoing line 4' is connected to a shielding part 14 of the wire 6. A pickup 7 which has the electric resistance not higher than about 10<10>OMEGA/cm is mounted to a core wire 12 at the other end of the wire 6. Lead wires 9, 10 of a resistance meter 8 are connected respectively to the outgoing lines 4, 4' of the coherer 1.
