Title: White balance correction circuit
Inventor: HOSOKI TOSHIAKI
IPC: H04N9/73
Filed: 1990-10-31
Abstract: PURPOSE:To improve the sharpness of a white peak level in terms of visual observation by correcting white balance of a signal in the vicinity of a maximum amplitude of a television signal toward a blue signal. CONSTITUTION:When each output signal of red R, green G and blue B reaches a voltage resulting from the sum of an emitter voltage of a transistor(TR) 11 and one diode forward voltage drop VF or two diode forward voltage drops VF, the limiter operation is started. The operating start voltage is set to nearly a maximum amplitude of a TV signal. An output voltage change after the start of limiter operation is caused by the resistance of resistors 5-10 connecting in series with each diode. Since the number of the diodes of a B signal line is larger than the number of diodes of other lines by one, the operating voltage of the limiter circuit with respect to the B signal is higher than that with respect to other signals by one forward voltage drop of the diode. When a white level signal resulting from arranged R, G, B signals is inputted to an output circuit having different limiter characteristics, the B output signal is expanded more than the R, G output signals. Thus, a white level peak of a white character or the like is blue on a cathode ray tube thereby increasing the sharpness in visual observation.

Title: Writing lead automatic feeder in x-y plotter
Inventor: WAKASUGI KAZUNORI
IPC: B43L13/02
Filed: 1987-11-25
Abstract: PURPOSE: To reduce the size and cost of an automatic lead feeder by disposing a lead container on the body side and utilizing the moving force of a writing head tar refilling thereby reducing the weight of the writing head. CONSTITUTION: A writing head 10 is moved downward from a lead container 302 on the body 2 side and when a pen P holding the pen holding part 12 of the writing head 10 is located directly under the opening/closing part at the pen P, the shutter is driven by the moving power of the writing head 10. Consequently, the shutter is opened and a lead in the lead container 302 drops through the opening of the shutter and inserted into the lead insertion hole of the pen P on the writing head 10 side. When the writing head 10 is moved to recede from the shutter, pushing force of the writing head 10 acting onto the shutter is released and the shutter is closed. Since the lead container 302 is disposed on the body 2 side, weight of the writing head 10 can be reduced and since no driver is required for lead supply, the size and cost of an automatic lead feeder can be reduced.

IPC: B22D11/112
Filed: 1991-10-18
Abstract: PURPOSE:To prevent the flow-out of slag in a tundish caused by whirlpool by fitting a stopper ring having cylindrical ring structure to a stopper and mixing molten steel of the preceding heat and molten steel of the following heat in the tundish. CONSTITUTION:The stopper ring 5 is limited to float up with a stopper ring fitter 13 during casting and dipped into the molten steel, but when the molten steel surface level becomes below the stopper ring fitter 13, this ring is floated up on the molten steel surface and prevents the whirlpool. By this method, the casting speed is high by fitting the stopper ring 5 and even in the case the molten steel surface level is low, the whirlpool is not developed, and the flow-out of the slag is prevented and the steel quality is improved and further, the yield is improved because of the decrease of the remained molten steel quantity in the tundish at the end stage of casting.

Filed: 1985-12-30
Abstract: PURPOSE:To attain the accurate position limit by driving a stepping motor so as to move a head and a position limit projection and changing the angular position of a stopper turning body so as to engage a stopper and the position limit projection with each other. CONSTITUTION:In driving the stepping motor 6, the head 5 and the position limit projection 44 are moved by the engaging between a screw 42 and an engaging body 39 and the angular position of the stopper turning body 48 is changed by meshing of gears 45, 46. When the turning body 48 comes to a prescribed angular position, the stopper 49 meshes with a projection 44 to block the turning body 48 from being turned. Thus, the drive of a rotor 40 by a motor 16 is blocked to stop the movement of the head 5. Then both the projection 44 and the turning body 48 are displaced depending on the drive of the common motor 6, the position limit is executed accurately and easily so as to decrease the deviation of the limit position due to the secular change.

Abstract: PURPOSE:To heat-treat a treated article with high efficiency and to prevent straining due to a temp. difference by embedding the article in a fluidized bed and intermittently introducing a fluidizing gas consisting essentially of He gas to alternately form a fluidized bed and a fixed bed. CONSTITUTION:An alumina powder 11 is placed in a fluidized-bed furnace 1, and the treated article 2 of spheroidal graphite cast iron at about 800-900 deg.C is set in the powder. He gas is supplied to the bottom of the furnace 1 from a cylinder 8 through a turbo fan 10 to fluidize the powder 11 on a dispersion plate 12. Consequently, the article 2 is efficiently and rapidly cooled by the high heat conductivity He gas to about 250-400 deg.C as the bainitic transformation point and austempered. In this case, the fluidizing He gas is intermittently introduced into the furnace 1 to alternately form a fluidized bed and a fixed bed. The article 2 is cooled with high efficiency by the high cooling effect of the fluidized bed and the gradual uniform cooling effect of the fixed bed, and the article is lowly strained.
