Title: Molten metal vessel providing weir
Inventor: ISHII TOSHIO
IPC: B22D11/118
Filed: 1986-08-08
Abstract: PURPOSE:To efficiently remove the inclusion in molten metal and to prevent the slag in clusion at the end period of casting by arranging horizontally a weir having plural holes opening toward vertical direction, so as to position near the molten metal discharging hole in the molten metal. CONSTITUTION:The molten steel 21 poured into a tundish 20 from a ladle is reached to the weir 34 as becoming the horizontal stream toward the arrow 29 direction and discharged into a mold 44 from the discharging hole 25 through a sliding nozzle 26 after passing holes 36 of the weir at almost uniform flow speed. When the molten steel 21 passes the holes 36, small eddy is developed at near the outlet side of holes 36 and the inclusion 35 in the molten steel 21 sticks to the lower face of weir 34 and does not mix into the mold 44. On the other hand, at the end period of casting, the pouring of molten steel in the ladle is stopped and the continuous casting is executed as adjusting the pouring rate of molten steel 21 by the sliding nozzle 26, and then, by lowering level of the molten surface, it becomes to develop the eddy at the zone just above the discharging hole 25, but by the weir member 30 arranged at here, the circular flow of molten steel is blocked and the development of eddy at the end period of casting is prevented.

Filed: 1987-07-29
Abstract: PURPOSE:To discharge a predetermined amount of a liquid only by tilting a container from an erected state, by using a volume reducing member for deforming or moving a container from the initial state when the internal pressure of the container becomes lower than external pressure to reduce the volume of the container by predetermined amount and returning the container to the initial state when the internal and external pressures of the container become the same. CONSTITUTION:A plurality of openings 12 are formed to the circular region 10 positioned at the right half part of the upper surface wall of a container body 4 and covered with the main part 16 of a volume reducing member 14. When a cap 18 is separated and a container 2 is tilted, liquid content 22 fills a discharge passage 6 to block the communication of an air space 20 with the outside of the container. The liquid content 22 is discharged and the volume of the air space 20 is increased by the discharge amount of said content and negative pressure is formed and the main part of the volume reducing member made of soft rubber is collapsed by the difference between the internal and external pressures of the container and the increment of the volume of the air space 20 is compensated. When the discharge of the liquid content is further continued, the volume of a space 20b becomes substantially zero corresponding thereto and the discharge of the liquid content becomes impossible. Therefore, the liquid content is discharged only in the predetermined amount corresponding to the volume of the space 20b being held to an initial state.

Title: Automatic releasing device for parking brake

IPC: B60T11/28
Filed: 1982-10-28
Abstract: PURPOSE:To relieve the driver of labor, by a method wherein a foot brake maintainined in a braking condition by operating a solenoid valve is released when the depression quantity of an accelerator pedal and the return quantity of a clutch pedal reach set points and the vehicle moves forwards. CONSTITUTION:When the vehicle is stopped after braking, a solenoid valve 19 is operated to inhibit a working fluid from being returned, and the foot brake is maintained in the braking condition. When the accelerator is depressed and the clutch pedal is gradually returned, the vehicle is set into a semi-clutched condition, and tends to move forwards. As a result, both an output from a comparator 8 and an output from a comparator 10 are made to be H respectively by an output signal from an acceleration sensor 1 and an output signal from a clutch sensor 3. Since an output from a comparator 12 is made to L by an output signal from a speed sensor 4 in response to starting of the forward movement of the vehicle, an output from an AND circuit 15 is made to be H, and an output from a flip-flop circuit 17 is made to be L. Accordingly, an output from an output circuit 18 is made to be L, so that the valve 19 is opened to release the braking condition.
