Title: Method for measuring overall heat absorptivity
Inventor: ENDO TOSHIO
IPC: C21D9/00
Filed: 1985-05-01
Abstract: PURPOSE:To measure overall heat absorptivity with a simple and quick measurement easily and accurately by coating a plate-shape material with a heat insulating material except the surface which is held exposed, loading such material into a furnace and measuring the inside temp. of the place where the depth from the surface is different. CONSTITUTION:The rear surface 3 and side surfaces 6 of a steel plate 4 are coated with the heat insulating material 2 and while the surface 1 is held exposed, the plate 4 is loaded into the furnace. The internal temp. of the steel 4 is measured by thermocouples 5, 5 at the two points where the depth from the surface 1 is different. The temp. distribution equation of the plate 4 is then calculated from the measured temp. as the parabolic line having the main axis within the rear surface 3. The overall heat absorptivity phiCG of the steel plate 4 in the loading position is calculated by using the equation indicating the quantity of heat transmission from the surface temp. of the plate 4 determined from the temp. distribution equation, the surface temp. gradient of the plate 4 determined from the differential equation for the temp. distribution equation and the measured temp. value of the combustion gas in the furnace.

Title: Offset canceling circuit
Inventor: OKAMURA TOSHIYUKI
IPC: H04B3/00
Filed: 1988-04-20
Abstract: PURPOSE:To suppress the turn-in quantity of power source noise to an output by bringing a signal to balance input to a positive phase input and an opposite phase input of an amplifier by an emitter follower of the same driving impedance. CONSTITUTION:As for a signal which has been inputted from a base of a transistor 7, an output of a positive phase is fetched as an emitter follower output from an emitter, and an output of an opposite phase is brought to level shift and fetched from a collector by an emitter follower consisting of a transistor 10, a diode 11 and a resistance 12. When a DC component of a positive phase output of an amplifier 13 has a higher offset than that of a DC component of an opposite phase output, an output voltage of an amplifier 18 rises, a DC component of a signal applied to the opposite phase input drops, a DC component of the positive phase output drops, and the offset can be canceled. In such a way, the signal is brought to balance input to a positive phase input and a reverse phase input of the amplifier 13 by the emitter follower of almost the same driving impedance, therefore, the turn-in quantity of a power source noise of both the inputs is canceled by the same phase component elimination ratio of the amplifier 13.

Filed: 1988-04-19
Abstract: PURPOSE:To reduce the mechanical dimensions ot the title antenna by arranging a primary radiator and auxiliary reflecting mirror in such a way that the whole mapping of the primary radiator and auxiliary reflection mirror projected on a plane containing the effective area of a main reflection mirror can be in the effective ares and, at the same time, can be offset from the center of the effective area. CONSTITUTION:Since the whole mapping of the primary radiator 3 and auxiliary reflection mirror 2 projected on the plane containing the effective area of the main reflection mirror 2 is in the effective area, the mechanical dimensions of this antenna coincides with the aperture of the main reflection mirror 1. Moreover, since the radio waves radiated from the radiator 3 are radiated into the space except the part intercepted by the auxiliary mirror 2 and a support 4 in the vicinity of the opening of the radiator 3 where the intensity of the electric field is high after the radio waves are reflected by the auxiliary and main reflection mirrors 1 and 2, deterioration of the radiating characteristics by means of the mirror 2 and support 4 can be reduced. Thus the mechanical dimensions of the whole body of this antenna can be reduced.
