Filed: 1984-08-18
Abstract: PURPOSE:To flush heads of printing lines, by a method wherein after manually feeding a paper, a stepping motor is excited to feed the paper forward by a predetermined number of steps, the paper is then fed reversely by the same amount, and a serration mechanism is switched over to the carriage-feeding side, thereby printing. CONSTITUTION:When the paper is manually fed, a rotor 12a of the stepping motor 12 is rotated whereby relative relationship thereof with a current-passing phase of a stator 12b is unbalanced. In the case of using a stepping motor 12 having four phases in a two-phase-on system, when a current is passed in the current-passing phase A to rotate the rotor (feed the paper) by two steps, a predetermined correlation is established between teeth (driving phase) B of the rotor 12a and the current-passing phase A of the stator 12b. Then, an electric current is again passed to the stator 12a to feed the paper reversely by the two-step amount, whereby the paper is fed back to a printing-starting position in the condition wherein the current-passing phase A and the driving phase B are matched to each other, then a gear of a slider 11 is engaged to a driving gear 13 on the carriage-feeding side by the serration mechanism 35, and printing is started.

Abstract: PURPOSE:To reduce an influence of noise radio waves and reduce the applied wind pressure of a dish due to air holes by providing a conductive radio reflection member consisting of a metallic thin plate, a plastic film on which a metal is vapor-deposited, or the like so that this member covers the point where the extension of the center line of a radiator of a converter intersects the radio wave reflection face of the dish. CONSTITUTION:A metallic thin plate 4 which is formed approximately equally in horizontal and vertical directions with the point, where the extension of the center line of a radiator 3 of a converter 2 intersects the radio reflection face of a dish 1, as the center when viewed from the focus part of the radiator 3 is attached to the radio reflection face of the dish, which is formed like a wire netting by forming air holes, as one body. The converter 2 is attached by a converter attaching metal fitting 5 while keeping accurate positional relations to the disk 1 and is attached to a pole brace 6 with an antenna attaching metal fitting 7 between. Then, most of noise radio waves passing through air holes from the back of the dish is reflected and does not come to the radiator 3 of the converter. Thus, the reception efficiency of the dish is improved, and the applied wind pressure is not raised because the size of air holes is increased by this improvement.

Title: Photocathode
Inventor: IKEDA JUNJI
IPC: H01J1/34
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a photocathode capable of obtaining a large amount of emission current even if a chemically stable material is used for an electron emitting surface. SOLUTION: If a stimulation light 5 is radiated from the back surface of a base, the light passes through a second metal mirror thin film 2b and enters a transparent base 1, and receives light amplification by an optical resonator composed of a first metal mirror thin film 2a and the second metal mirror thin film 2b. As a result, amplified light is radiated on an electron supply film 30, and thereby, an electron 7 emitted from a photocathode film 3 is radiated into a vacuum 6. This emitted electron 7 is accelerated by a voltage VA applied on an anode 4, is collected at the anode 4 so as to cause an electric current IE. Since the electron is stimulated by the light amplified by light amplification, a large amount of emission current can be obtained even if a chemically stable material is used for a photocathode film.
