  • Publication number: 20230059189
    Abstract: The electrostatic printing method of the present invention comprises arranging and adhering an original plate which is composed of an electrode and a plate layer having built-in a letterpress, intaglio plate, or gravure plate pattern or a mask sheet having ion-permeable openings on one or both sides of an image receiving sheet having an electrode and an image receiving layer, and forming a predetermined electrostatic pattern on the image receiving layer of the image receiving sheet by applying a voltage between the electrode of the original plate and the electrode of the image receiving sheet or by performing ion irradiation through the mask sheet.

  • Patent number: 8387159
    Abstract: The present invention provides a fast-operating and stable scanning probe microscope configured to detect the interaction between a probe and a sample to avoid generation of a harmonic component. An oscillation circuit (31) generates an excitation phase signal indicative of the phase of an excitation signal. An excitation signal generation circuit (33) generates an excitation signal from the excitation phase signal. A complex signal generation circuit (35) generates a complex signal from a displacement signal. A vector calculation circuit (37) calculates the argument of the complex signal. A subtracting phase comparator (39) compares the argument with the phase of the excitation phase signal by subtraction. The amount of the interaction between a probe device and a sample is obtained using the subtracting phase comparator (39). The result of the comparison carried out by the subtracting phase comparator (39) may be output as a difference in phase between the displacement signal and the excitation signal.

  • Patent number: 6301472
    Abstract: A switching system (3) has, in addition to an ordinary accounting function, an origination-only accounting control unit 6 to monitor the number of message units used by an origination-only portable telephone (1B) identified by a terminal identification number and to deny the origination of a call by the origination-only portable telephone (1B) upon the increase of the number of used message units to a predetermined number. The origination-only accounting control unit (6) accepts the origination of a call made by the origination-only portable telephone (1B) when a prescribed input about the origination-only portable telephone (1B) is given thereto by a system operator by operating a predetermined terminal device (7) or the like after the denial of origination of a call by the origination-only portable telephone (1B).

  • Patent number: 3991040
    Abstract: New curable monomeric aromatic imidodicarboxylic acid diallyl esters, such as 4-allyloxycarbonyl-N-(allyloxycarbonylmethyl)phthalimide, 1,2-ethylene bis(4-allyloxycarbonylphthalimide), or N,N'-bis(allyloxycarbonylmethyl) pyromellitimide. When heated in the presence of a free radical initiator, these monomers give cured polymers having very superior mechanical strength, thermal stability, chemical resistance and electrical properties. If this polymerization is stopped before the reaction mixture is gelled, prepolymers can be obtained. The cured polymers are especially useful as electronics materials and engineering plastics.
