Title: Pressurize die casting method and normal/defective condition discriminating method of casting thereby
Inventor: TAKAGI HIROMI
IPC: B22D17/22
Filed: 1990-11-09
Abstract: PURPOSE:To prevent a shrinkage cavity from generation by using an optimum relation previously obtained and pressurizing the material in the optimum condition corresponding to a die temperature and a primary pressurization continuing time which are measured in casting. CONSTITUTION:When the casting preparation for a die cast machine is completed, the die temperature is measured, then, the primary pressurization wave form of an injection plunger 7 is measured to obtain a primary pressurization continuing time. An optimum secondary pressurizing speed and an optimum secondary pressurization commencing time are calculated with the die temperature and the primary pressurizaton continuing time which are measured based on the optimum relation curve. Then, the secondary pressurizing speed and the secondary pressurization commencing time which are calculated are inputted into each controller. That is, the pressurization commencing time is controlled by an opening/closing signal of a solenoid valve 23 and the pressurizing speed is controlled by the opening degree control signal of a flow control valve 18. Consequently, the pressure drop accompanied with the lapse of the pressurizing time is decreased drastically to obtain a satisfactory pressurizing effect. Further, shrinkage cavities are prevented extremely effectively from generation and the balance of specific gravity is reduced remarkably.

Title: Method for detecting developing condition of bare slag and device for removing bare slag
Inventor: GOTO ATSUHIRO
IPC: B22D11/16
Filed: 1988-11-30
Abstract: PURPOSE:To detect bare slag during operation at good accuracy by arranging one pair or plural pairs of image sensors for detecting molten metal surface condition at the facing position sandwiching a pouring nozzle. CONSTITUTION:Upper surface part 1b of the mold has comparatively high brightness, because light reflects. On the contrary, temp. in surface part of powder 4a, which is not yet melted, is low, because of the powder layer just spread and the reflection ratio of the light is low, because of the solid powder and the brightness is low level. Then, when the bare slag 5 develops, the temp. of the stuck position A of the bare slag 5 to the mold wall face 1a is low, because there is cooled with the mold 1 and further, as this has characteristic, which is difficult to reflect the light, the brightness is extremely low. On the other hand, when the bare slag 5 does not develop, the powder 4a, which is not yet melted, uniformly covers on the molten metal. Therefore, by obtaining the brightness distribution near the molten metal surface on the line contacting with the mold 1, the detection of the molten metal condition is performed, and particularly the developing condition of the existence of the bare slag, the quantity thereof, can be informed.

Title: Electromagnetic actuator
Inventor: YAMAMOTO YOSHIO
IPC: H01F7/16
Filed: 1986-12-19
Abstract: PURPOSE:To obtain an electromagnetic actuator which can work with small coil magnetomotive force by having a coil to excite a self-maintaining magnetic circuit and by making a movable iron core movable up to a position, where it reaches out of the self-maintaining magnetic circuit including a movable plunger when a coil is excited. CONSTITUTION:When a current is conducted to a coil 20 for a short time in the direction where magnetization is generated in the same direction as the magnetization of a permanent magnet 16, a movable iron core 24 increases the force for moving in the direction, where magnetic resistance reduces, and moves to the side of the coil 20 resisting against the reaction force of a spring 27. As a result, the magnetic circuit of the permanent magnet 16 not including the attraction part 25 of a movable plunger 19 is formed so as to sharply decrease coercive force toward the movable plunger 19 and to perform repelling action by the force of a spring 26. Accordingly, when a valve is provided on the top part of the movable plunger 19, it can be used as a safety valve. Further, when a current conduction generating magnetization in the reverse direction of that of the permanent magnet 16 is performed for a short time, the movable iron core 24 moves again to a position distant from the coil 20 by means of the repelling force of the spring 27.
