Title: Led driving circuit
Inventor: WAKATA HIDEYUKI
IPC: H01L33/00
Filed: 1987-11-07
Abstract: PURPOSE:To prevent the change of impedance, by connecting an LED flashing switch in parallel to an LED, making the switch close at the time of ON, and making a stationary current constantly flow through the LED at the time of OFF. CONSTITUTION:An LED flashing switch 3 is connected in pallalel to an LED 1. When an 'H' level voltage supplied to the base of an NPN transistor Tr 3 through a terminal L3 is cut, the transistor Tr 3 is turned OFF. The current of a constant current source is not absorbed by the Tr 3. The current flows through the LED 1, and the current flows between a terminal 1 and a terminal 2 for LED lighting. Therefore a constant current flows through the Tr 3 at the time of ON, and flows through the LED 1 at the time of OFF. Thereby preventing the change of impedance.

Title: Stock powder preheating apparatus with waste heat utilizing equipment
Inventor: FUJISAWA TETSUO
IPC: C04B7/44
Filed: 1985-12-14
Abstract: PURPOSE:To efficiently recover the sensible heat of exhaust gas, by arranging a shortcircuit gas conduit opened not only to the duct of a lower stage or the inlet end of a combustion furnace at one end thereof but also to the exhaust gas duct reaching the waste heat utilizing equipment of an exhaust system at the other end thereof. CONSTITUTION:Because the hot gas extracted from a gas duct 7a is not used in the heat exchange with the stock powder in the downstream side of the gas extraction part and retains high temp., said hot gas is allowed to meet with the exhaust gas in a gas duct 15 to raise the temp. of the exhaust gas finally introduced into a boiler 16. Therefore, the heat recovered in the boiler 16 increases to a large extent and, at the same time, the temp. and pressure of generated steam become high and, therefore, the power generation efficiency in a turbine is markedly improved. When a flow controller 20 is provided to the proper place of a shortcircuit gas duct 19 and a shortcircuit hot gas amount is controlled, the temp. of the exhaust gas introduced into waste heat utilizing equipment can be enhanced to arbitrary temp.
