Filed: 1988-12-12
Abstract: PURPOSE:To prevent the coupling noise of a signal line by providing a dummy scanning line, which is changed from a non-selective level to a selective level, contrary to a scanning line in an active matrix constitution from the selective condition to the non-selective condition. CONSTITUTION:An effective screen consists of scanning lines G1 to G480 and signal lines D1 to Dn, and in order to offset a coupling noise mounted from the scnaning line onto the signal line, two dummy scanning lines DG1 and DG2 are provided on the lower side of the effective screen. The dummy scanning line DG1 corresponds to a scanning line driving circuit GDL, and the dummy scanning line DG2 corresponds to a driving circuit DGR. That is, the dummy scanning line DG1 is level-changed on an antiphase basis to the selecting operation of odd-number-th scanning lines G1, G3,... G479 by the driving circuit GDL, and the dummy scanning line DG2 is level-changed on the antiphase basis to the selecting operation of even-number-th scanning lines G2, G4,... G480. Thus, the coupling noises of the scanning line and dummy scanning line with respect to the signal line are mutually canceled, and the coupling noises can be prevented from being generated.

Abstract: PURPOSE:To contrive the preventation of the production of a rounding error and to reduce the time required for D/A conversion by adding the output of a 1st D/A conversion circuit D/A-converting an input digital signal and the output of a 2nd D/A conversion circuit D/A converting the output of a digital integration circuit at a prescribed rate. CONSTITUTION:The operation multiplying a coefficient with an input digital signal is not applied by digital processing, the D/A conversion is applied by the 1st D/A conversion circuit 5, while the digital input signal is integrated digitally by a digital integration circuit 4 to apply D/A conversion by the 2nd D/A conversion circuit 6 and the analog outputs of the 1st and 2nd D/A conversion circuits are added by a prescribed rate. Since the rate of the addition has the effect of the multiplication of the coefficient, no digital signal addition is required. Thus, no bit number is increased for the 1st and 2nd D/A converters and the extended conversion time and the rounding error is not produced.

IPC: B22C9/06
Filed: 1992-10-29
Abstract: PURPOSE:To minimize an occurrence of an internal strain to prevent an occurrence of a warpage and a sink mark to enhance the accuracy by a method wherein a plaster casting mold is heated to a melting point or thereabouts of a low-melting alloy in a heater form, the low-melting alloy is cased into the heater form, the temperature of the heater form is lowered to a specific point in a specific cooling pattern, and thereafter the casted piece is naturally cooled. CONSTITUTION:A plaster casting mold 11 with an insulating plate 12 disposed under the bottom surface thereof is sucked by a vacuum pump 13. Succeedingly, a low-melting alloy 14, e.g. a zinc, reaching its melting temperature is casted into a heater form 10. After that, the temperature of the heater form 10 is kept at the melting point for 10 minutes, thereafter being lowered stepwise by 10 deg.C at an interval of 10 minutes. After the heater form 10 is cooled to 200 deg.C, an electric conduction is interrupted, and the low-melting alloy 14 is kept to be naturally cooled. A simplified injection mold 16 is obtained by detaching the heater form 10 and removing the plaster casting mold 11 from the low-melting alloy 14 cooled and set. The low-melting alloy 14 cooled to approximately 200 deg.C never generates a significant internal strain even after being naturally cooled.

CONSTITUTION:When a starter motor 14 is operated at the starting time, a driven starter gear 8a is deceleratedly driven widely via idle gears 16-18. Rota tion for strating is transmitted to a crank shaft 4 via a dog clutch 12 and a one-way clutch 9. The crank shaft 4 and the driven starter gear 8a are separated by the clutch 9 after the starting. A the starting time, when timing of ignition with piston action does not meet, the crank shaft 4 is apt to perform reverse rotation, impulsive reverse rotation torque is performed at this time via the one-way clutch 9. To the driven starter gear 8a, however, the reverse torque is transmitted via a damper rubber 13 provided at the dog clutch 12. Trouble is prevented without giving a strong shock to the idle gears 16-18 and the starter motor 14.

Title: Method and device for removing slag in frame
Inventor: ITO MIKIO
IPC: B22C9/08
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To surely remove the slag with a simple structure by filling a molten metal in an expansion part in a short time to allow the slag to be afloat by a gate which is provided on the downstream side of the section expansion part in a horizontal runner and formed of an iron plate. SOLUTION: When a molten metal 15 is poured in a sprue 3 of a mold from a ladle, the molten metal 15 containing the slag 20 enters a horizontal runner 5a from a longitudinal runner 4. A gate 7 is provided on a boundary between an expansion part 6 whose section is partially and abruptly expanded and a horizontal runner 5b on the downstream side to throttle the sectional area of a flow passage. Most of the molten metal thus fills the expansion part 6 while reducing the speed in the expansion part 6 without entering the horizontal runner 5b. In this process, the slag 20 which is far lighter than the molten metal is allowed to be afloat, and stored in an upper part of the expansion part 6.  When the expansion part 6 is filled with the molten metal 15, the molten metal flows in a groove part at a lower part of the gate 7 at higher speed, carbon is diffused to the groove part, the melting point is dropped, the part is melted in 2-3 seconds, the groove part is expanded to pour the molten metal in a product mold.

Abstract: PROBLEM TO BE SOLVED: To obtain a die for edging press devices with which the width of a hot slab is reduced to a prescribed width with high accuracy by making the boundary part between the parallel part and the inclined part of the die for edging press devices for pressing the hot slab into the prescribed width into a smoothly curved line shape. SOLUTION: In this die for edging press devices, the boundary part between the parallel part 2 and the inclined part 3 is made into the smoothly curved line shape the radius of the circular arc of which is 200-10000nm. And, press work is executed taking the feed rate F a time of the hot slab as >=1 time the length L0 of the parallel part of the die. A radius R3 is provided in the rear end part of the die 1, because, when there is an angle in the rear end part of the die 1, there is a possibility that an acute part is generated on the side faces of the slab to be reduced and flaws are made to remaine on a hot steel strip. So, it is desirable to make the rear end part into a curved line shape by providing the circular arc of the radius R3 .
