  • METHOD OF PRODUCING MOLDED PRODUCT, RESIST FOR COLLECTIVE MOLDING WITH IMPRINT-ELECTRONIC LITHOGRAPHY, METHOD OF PRODUCING REPLICA MOLD, METHOD OF PRODUCING DEVICE, AND IMPRINT MATERIAL
    Publication number: 20210397097
    Abstract: A method of producing a molded product, the method including: pressing a mold having a surface including at least one of a concave part or a convex part against a photocurable positive electron beam resist; obtaining a molded product of the positive electron beam resist having a surface including a concave part and a convex part by irradiating the photocurable positive electron beam resist pressed against the resist with light to cure the resist; and partially decomposing the molded product of the positive electron beam resist in a region subjected to irradiation with an electron beam by irradiating the surface of the molded product of the positive electron beam resist with the electron beam.

  • Electronic circuit unit
    Patent number: 9814147
    Abstract: A housing includes a first chassis and a second chassis which are each formed of a metal sheet. Support projections integrally formed with support pieces formed in the first chassis are fitted into support holes of a circuit board on both left and right sides of a connector. A lower surface of the circuit board is supported by receiving portions formed in the support pieces, and part of the circuit board facing the connector is pressed downward by a pressing projection formed in the second chassis.

  • EDM control system to maximize efficiency by controlling the gap width
    Patent number: 4703144
    Abstract: An electric discharge machine has a CPU that controls a switching element that supplies a pulse voltage to the gap between an electrode (which may be a wire electrode) and a workpiece. The CPU is able to determine the average pre-discharge time (the average time between the turning on of the switching element and the start of each electrical discharge) based on the sampling time interval and the counted number of discharges that occurred during the sampling time interval, by turning off the switching element at a set time after the start of each electrical discharge, and turning the switching element on again after a longer set time has elapsed from the start of each electrical discharge. The average gap voltage and average gap current are then calculated and displayed from this data.
