IPC: A61C13/15
Filed: 2001-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a lightweight and compact photocuring device for efficiently irradiating an irradiation object with light from a light emission diode with high reliability and high light output without irradiation unevenness. SOLUTION: This irradiation device for photocuring has a light emission diode emitting light of 350-500 nm in peak emission wavelength, and a radiator 12 formed of a heat pipe is brought into close contact with the back face of the light emission diode through a heat conductive joint material 13.

Title: Pump for powder
Inventor: SAEKI RYOJI
IPC: B65G65/46
Filed: 2001-10-16
Abstract: PROBLEM TO BE SOLVED: To solve problems involving the powder pump that conveyance by screw is difficult in case the powder is so fine and low in mass and therefore hardly fluidized, that blocking by coagulation is inevitable during conveying despite air injection for fluidity enhancement, and that the outlet nozzle must have an opening/closing valve for a metering pump. SOLUTION: Liquefaction phenomenon is caused to the powder by applying vibration via a housing to stably convey low-fluidity powder. A sliding piston opens and closes the discharge port by discharge action from a sleeved port provided at the sleeve end of a cylinder. The opening and closing of the nozzle occurs instantly, without pressing and solidifying the screw-conveyed powder.
