  • Publication number: 20210228315
    Abstract: A hardenable (e.g. dental) compositions is described comprising an encapsulated material. The encapsulated material comprises a basic core material and an inorganic shell material having certain viscosity criteria. Also described are dispensing devices and kits are described comprising a hardenable (e.g. dental) composition comprising a liquid material and an encapsulated material wherein the encapsulated material comprises a basic core material and an inorganic shell material comprising a metal oxide surrounding the core. The dispensing devices and kits can facilitate the methods of applying the hardenable composition. The hardenable or hardened (e.g. cured) composition can provide various technical effects such as a delayed release of a basic core material, a delayed increase in basicity, promoting remineralization of a tooth or bone structure, and increasing the average alkaline phosphatase (ALP) activity of pulp cells. In some embodiments, the composition is a dental (e.g.

  • Patent number: 10708989
    Abstract: A control unit controls a bidirectional switch so as to turn the switch from ON to OFF when an amount of time, varying according to a lighting level, passes since a starting point of a half cycle of an AC voltage. When a voltage between both terminals of a capacitive element, connected to a control terminal of the bidirectional switch, becomes equal to or greater than a threshold voltage, the bidirectional switch turns from OFF to ON A first charging/discharging regulator circuit and a second charging/discharging regulator circuit each make a rate of fall of the voltage between both of the terminals of the capacitive element when the bidirectional switch turns from ON to OFF lower than a rate of rise of the voltage between both of the terminals of the capacitive element when the bidirectional switch turns from OFF to ON.
