Title: Superconducting functional device
Inventor: NAKAO MASAO
IPC: H01L39/24
Filed: 1992-12-07
Abstract: PURPOSE:To obtain a superconducting functional device which utilizes a quantum phenomenon as its device operation principle by a method wherein a conductance is periodically controlled in accordance with the value of a superconducting current. CONSTITUTION:A phase difference delta is produced between electron waves which enter a quantum wire 14 through a contact 13a and are propagated through the channel parts 14a and 14b of the quantum wire 14 with a single mode by a magnetic field B which is generated by a current flowing through a control wiring 11 made of superconducting material. When the electron waves come out of the quantum wire 14, the waves interfere each other and are outputted from a contact 13b. The phase difference delta between the electron waves which are propagated through the channel parts 14a and 14b depends upon the magnitude of the magnetic field B formed by the current applied to the control wiring 11. With this constitution, a superconducting functional device whose conductance is varied in accordance with the value of the superconducting current can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a new initializing method of an information record medium and device therefor capable of performing an uniform crystallization throughout the whole of the record medium. SOLUTION: On a recording film surface, the width of a beam spot 9 (half value of a peak power) x [μM] and the length of the peak spot (half value of the peak power) y [μm] are set so as to be 3<x<20 and 20<2Pη<80. P [W] is the output power of a laser and η is the efficiency of an optical system. The beam is arranged so that the longitudinale direction of the beam forms an angle other than an angle parallel with recording tracks 10 similarly with the conventional manner. Thus, the reflectance unevenness due to the lapping of the beam spot 9 is prevented and a sure initial crystallization is performed in a short time.

Abstract: PURPOSE:To take out a chemical liquid without coming into contact with a gas or a liquid at the outside by a method wherein a hermetically sealed container is formed to be of double structure, an inside container is formed of a soft material so as to be capable of being expanded and contracted, a pressure is exerted between an outside container and the inside container and the chemical liquid is taken out from the inside container. CONSTITUTION:An inside container 2 which can be expanded and contracted is installed newly at the inside of a hermetically sealed container 1; a gas or a liquid for pressurization use can flow into the gap between the outside container 1 and the inside container 2. In a state that a chemical liquid 6 has been filled into the inside container 2, a fluid such as a gas, a liquid or the like is injected at a prescribed pressure from an inflow port 4. Then, the fluid flows into a part between the hermetically sealed liquid-housing container 1 and the inside container 2, and a pressure is exerted on the outside of the inside container 2. When the pressure is exerted, the inside container 2 is compressed, its volume is reduced and the chemical liquid 6 can be taken out from an inside- liquid takeout port 3. Thereby, the chemical liquid can be fed out while the chemical liquid does not come into direct contact with a gas.

Abstract: PURPOSE: To surety detect trespass and to prevent the occurrence of an erroneous alarm by providing two different detectors in the same protected area and giving an alarm only at the time when both detectors are operated in a specific mode. CONSTITUTION: If a glass window is pushed, broken, or holed in a protected area, a crash sound of glass is emitted, and the pressure in the room is varied. This sound is recorded by a glass break detector 30, and the pressure variance is recorded by a pressure detector 10. Since the propagation speed of the pressure wave is lower than that of the acoustic wave, the pressure variance is detected with a delay of about 0.1sec. For the purpose of preventing an erroneous alarm, the glass break detector 30 is constituted as a microphone, and sounds on the outside of the frequency range of the sound caused by glass break are suppressed through a band pass filter 35. A band pass filter 15 is used to transmit only the variance peculiar to glass break. Further, an alar, is given in response to the variance peculiar to glass break by the delay time of a time delay circuit 45.
