Filed: 1980-12-11
Abstract: PURPOSE:To confirm a size correspondence between an original and a form by controlling the lighting of a warning lamp by processing an original-size and a copying-paper-side signal logically. CONSTITUTION:An original of A4 size, etc., turns off the switch SW2 of the original mat of the 1st detecting means 13. Then, high-level outputs from switches SW1 and SW3 and a low-level output from a switch SW2 through an inverter 26 permit only an AND gate 34 to generate a high-level output, so that only an AND gate 40 is opened. When this gate 40 is applied with a high-level signal generated when copying paper of A4 size is detected by the 2nd detecting means 37, a transistor 50 which controls the lighting of a warning LED52 through an inverter 46 turns off. Other sizes are the same and only when the size of an original is coincident with that of copying paper, a warning lamp turns off to confirm a size correspondence between the original and form, thereby preventing unnecessary copying operation.

Title: Superconducting optical memory device
Inventor: SAKAI KIYOMI
IPC: G11C11/42
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To capture the magnetic flux depending on the intensity of light and the magnitude of applied current in a superconductor loop and to make the rounding current flow after the cut-off of an external current by partially modulating the superconducting current by irradiating the light to a part of a superconducting loop, on which the current is applied. SOLUTION: The superconducting material of YBa2 Cu3 O7-x is used. When a current is made to flow from an electrode 11 to an electrode 12, currents J1 and J2 having the same quantity flow in the same direction in two circuits in a superconducting loop. At this time, when the very short pulse light is introduced into the light irradiated region, the current J1 is instantaneously decreased, and the high-speed change without influence is generated in the current J2. Since the magnitudes of the currents J1 and J2 are different, magnetic flux is captured in a hole 10. Accompanied by the input of very short pulse light, the superconducting current is instantaneously decreased and then recovered. This modulating time is about 1 picosecond. Then, before the application of the current, there is no detection of the electromagnetic waves.  In synchronization with the current application, the optical pulse is applied. Based on the electromagnetic waves irradiated after the cut-off of the current, the capture of the magnetic flux is confirmed.

Abstract: PROBLEM TO BE SOLVED: To provide a capacitor array with which the generation of crosstalks can be reduced. SOLUTION: Multiple inner electrodes 22, each having a specified area, are placed with specified spaces to form an inner electrode layer. An approximately rectangular parallelepiped element is formed by alternately layering inner electrode layers and dielectric layers 21a and 21b.
