Title: Sliding valve device having mechanism for preventing surface opening
Inventor: KITA YUKIO
IPC: B22D11/10
Filed: 1986-03-06
Abstract: PURPOSE:To prevent steel leakage by surface opening and to extend the life of a plate brick by applying a surface pressure in the ordinary stage by means of a surface pressure applying spring and acting a surface opening preventive spring when foreign matter begins to be engaged with a sliding surface. CONSTITUTION:A bottom plate 22 is built into a housing 21 and a sliding plate 23 is built into a sliding case 24. The surface pressure is applied to the sliding surface 28 by a toggle mechanism 40. A wedge 36 of a surface opening preventive device 31 is inserted into between a pin 30 and piece 33 of a holder 26 of the surface pressure applying spring 27 and is stopped at a suitable position by a spring plunger 37. The pin 30 acts in the direction of an arrow 29 and transmits the power to the piece 33 via the wedge 36 when the foreign matter engages with the sliding surface 28 during the casting operation and when the surface opening begins to arise as said foreign matter slides the plate 23. The force of the surface opening preventive spring 34 is then acted to increase the surface pressure. The foreign matter is thereby cut or broken to prevent the surface opening. The wedge 36 contacts the bottom surface 41 of a frame 32 when the foreign matter cannot be largely cut. The pin 30 does not move any more and therefore the surface opening size is controlled by a projecting length 39 of the piece 33.

SOLUTION: The required amount of a liquid in a storage tank 20 storing a large amount of the liquid is fed into an intermediate tank 24 by a liquid feed pump 22, and the liquid stored in the constant amount in the intermediate tank 24 is passed through a piping 26 and fed into a pump (a filling machine) 27 and filled from a filling nozzle 28 into a container 29. At that time, signals from a liquid level detecting sensor 25 for sensing the liquid level in the intermediate tank 24 are transmitted to the liquid feed pump 22 and a solenoid valve 23, and the liquid fed from the storage tank 20 is controlled in compliance with the liquid level in the intermediate tank 24 and the liquid level in the intermediate tank 24 is kept within the given range.  The intermediate tank 24 is so set as to form the liquid level below the position of the pump 27 so that the effect of liquid pressure is avoided to improve the filling accuracy.

IPC: H02H7/26
Filed: 1990-02-28
Abstract: PURPOSE:To shorten time required for detecting a fault zone by providing a high speed fault detector for sampling fault detection information, processing a predetermined calculation, comparing it with a specified value stored in advance and detecting a fault on a corresponding power distribution line. CONSTITUTION:A master station 40 detects the abnormality of a fault line based on output information of high speed trouble detectors FD1, FDk. If a short-circuit fault occurs on a power distribution line F11, a line current detecting current detector CT1 or CT2 detects a line current Ia or Ic. The current Ia or Ic is sampled, input to a RAM, and the average or effective value of the currents Ia, Ic is calculated by a CPU. It is compared with the content of a ROM which stores a specified value in advance. As a result, if the line current exceeds the specified value, it is immediately informed to the station 40 as a short-circuit trouble.

Abstract: PURPOSE:To determine an optimum coil pattern and to realize improvements in linearity and output efficiency while decreasing noises by dividing a flow function of electric current on the surface of a cylinder having a predetermined radius into those of magnetic coils inclined in the directions X and Z, representing them by a common function with a variable of positional coordinate in the axial direction of the cylinder, and varying this function with the repetitive process starting from the initial functional form thereof such that a square root sum of a difference between the function and a desired magnetic field at a representative point is decreased. CONSTITUTION:Relation of flows of electric current on the surface 5 of a cylinder having a predetermined radius is represented by psi(z, theta) where (z) is a axial position of the cylinder and is an angle in the circumferential direction. The function is defined as psi(z, theta)=f(z) costheta for a magnetic field coil inclined in the direction X and as psi(z, theta)=f(z) for the magnetic coil inclined in the direction Z. Then, the repetitive process is conducted, starting from the initial functional form of f(z), and f(z) is varied such that a square root sum of a difference between f(z) and a desired magnetic field at a representative point is decreased. A pattern is determined by a value of f(z) selected from many values of f(z) thus obtained. In this manner, linearity or output efficiency can be selected as required with an increased degree of freedom.

Title: Check system for cache memory
Inventor: ITO HIROMICHI
IPC: G06F12/08
Filed: 1988-03-01
Abstract: PURPOSE:To improve reliability without reducing an access speed by checking a cache memory by means of using the idle time of the action of the cache memory. CONSTITUTION:When the copy of data of a main storage device 4 which a CPU 1 accesses does not exist on the cache memory, data is accessed from the main storage device 4. At that time, data accessed from the main storage device 4 and the high order bits of the address of data are respectively written in a BS (Buffer Strage) 3 and AA (Address Array) 2 in the cache memory and the writing terminates at a short time since memory elements used for AA2 and BS3 are at high speed. Since the main storage device is in a low speed on the other hand, the cache memory comes to wait for the access termination of the main storage, and the cache memory is checked by using the wait time. Thus, the reliability of AA2 and BS3 consisting the cache memory can easily be improved without reducing the access speed of the cache memory.

Filed: 1990-02-28
Abstract: PURPOSE:To enhance transmission efficiency to a large extent by sampling the max. value in the unequal interval cycle of a radar video signal at every unequal interval cycle to issue output at an equal interval. CONSTITUTION:A radar video signal 5 is sampled by an equal interval sampling signal 6 and the digital radar video signal 7 thereof is inputted to a max. value detection means 2 within the cycle of an unequal interval sampling signal 8 and the max. value of the radar video signal is detected. Only a max. value video signal 9 is stored in a memory means 3 and the max. value thereof is read by a reading signal 11 of a definite interval. Herein, since the unequal interval sampling signal 8 is one gradually increased in its cycle as a distance becomes long, one max. value is detected from more radar video signals 7 in a long distance part and, therefore, the compression quantity of signals in the long distance part is enhanced and transmission capacity or a transmission band can be reduced.
