Title: Corner cracking preventing method for steel piece
Inventor: KANEMOTO MICHITAKA
IPC: B22D11/04
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent a corner cracking of steel pieces such as a billet without lowering a casting velocity by cooling a portion which is within a given %, of the side length and apart from a corner by a given % or more of the side length per side of a steel piece cross section as a range to be directly cooled. SOLUTION: According to a continuous casting machine, after a molten steel in a ladle is once poured into a tundish, the molten steel is flowed into a mold via a nozzle per strand. Simultaneously with the solidification of a surface, a steel piece 16 is pulled out by a roller while being gradually cooled by a secondary cooling water 15 for carrying out continuous casting. At the time of secondary cooling of the steel piece 16 being cast by the continuous casting device, corner cracking of the steel piece 16 is prevented by cooling the portion which is within 80% of one side length W1 and apart from a corner portion 16a by 10% or more of the side length per side of the steel piece 16 cross section.

Abstract: PURPOSE:To obtain desired exposure corresponding to an intention of composition, by providing a flash light emission quantity setting part on the electronic flash side, so that light emission of the electronic flash can be continued even after the exposure to a main object to be photographed has become correct. CONSTITUTION:By a photodetector 15, the light emission quantity of a xenon discharge tube 10 is detected, and an optical current corresponding to the light emission quantity is generated in the photodetector 15. Charging voltage of an integral capacitor 18 is an integral compressed value of the optical current of the photodetector 15, and is inputted to one input terminal of a buffer memory 23, a capacitor 27 for a light emission quantity memory, and a comparator 28.

Title: Controller of picture amplitude
Inventor: TAKESHITA MASAHIRO
IPC: H04N3/22
Filed: 1982-10-08
Abstract: PURPOSE:To control the amplitude of screen independently of the lightness of the screen of a cathode ray tube, by connecting the 1st resistor between a low potential terminal of the secondary winding of a flyback transformer and a reference potential point in a television receiver and connecting the terminal to a vertical deflection current adjusting circuit via the 2nd resistor. CONSTITUTION:A resistor 12 is connected between one of a high potential output winding 7 of the flyback transformer and ground. One end of a resistor 17 is connected to a cross point between a resistor 15 and a capacitor 16, and the other end is connected to a cross point between the resistor 12 and the winding 7 of flyback transformer. A vertical amplitude adjusting circuit reduces a vertical deflection current when a charging voltage of the capacitor 16 is decreased, and when the anode current of the cathode ray tube is increased and the anode voltage is dropped, and voltage at the cross point between the resistor 12 and the winding 7 is reduced, resulting that the voltage is connected to the capacitor 16 via the resistor 17, then the voltage of the capacitor 16 is reduced. Thus, the vertical amplitude of the screen is made constant, even if the anode voltage of the cathode ray tube is decreased by selecting the resistor 17 when the vertical deflecting current is decreased.
