  • Publication number: 20200187755
    Abstract: Provided are an adhesive for an endoscope, a cured product, an endoscope, and a method for producing an endoscope. The adhesive for an endoscope is a two-component adhesive for an endoscope. The two-component adhesive has a base and a curing agent. The base includes at least one epoxy resin (A) selected from the group consisting of bisphenol A epoxy resins, bisphenol F epoxy resins, and phenol novolac epoxy resins. The curing agent includes a tertiary amine compound (B). The tertiary amine compound (B) accounts for 60 mass % or more of a curing component included in the curing agent.

  • Patent number: 4892080
    Abstract: A high-energy ignition system for an internal combustion engine in which both magnetic and electrical energy stored in an energy storage coil and in a capacitor are supplied to the primary winding of an ignition coil at a predetermined timing. When a first or second switching device is turned off, the capacitor is charged with the energy stored in advance in the energy storage coil, and upon subsequent turning on of the first switching device, energy is stored in the energy storage coil from a DC power supply. At substantially the same time as the turning off of the first switching device at an ignition timing, the second switching device is turned on to supply the primary winding with the energy stored in the energy storage coil and the capacitor. Alternatively, the capacitor is charged with the energy stored in advance in the energy storage coil through the primary winding of the ignition coil and a charging diode at the time of turning off of the second switching device.

  • Patent number: 4641626
    Abstract: A current-interrupting type ignition device having an ignition coil having a primary winding, a secondary winding and an auxiliary winding disposed in the primary circuit, the number of turns of the auxiliary winding being less than that of the primary one. The auxiliary winding is energized in such a manner that electromagnetic flux passes in a direction opposite to that of the primary winding when energized. In this arrangement current flows through the auxiliary winding via a transistor and a diode when the primary current flowing through the primary winding is interrupted, thereby adding a voltage induced across the secondary winding by the transferring effect upon the energization of the auxiliary winding to the corresponding high voltage induced across the secondary winding upon the interruption of the current flow through the primary winding.
