IPC: H04N1/40
Filed: 1986-08-05
Abstract: PURPOSE:To obtain the output picture of a high quality by obtaining the maximum value and the minimum value of the differential values of the variable density values of an original picture by scanning them through a window for discriminating regions, and discriminating a binary picture region from a halftone picture region by comparing the difference between the maximum value and the minimum value with a prescribed threshold. CONSTITUTION:An 8 bits density data in a picture memory 2 is supplied to a differential arithmetic circuit 7, the differential value is obtained by a differential operation through the second differential operator of 3 X 3. The differential value is supplied to an arithmetic circuit 9 through an m-line buffer 8, and the maximum value max and the minimum value min of the differential values are obtained in the window of 5 X 5, then, a differential value difference D (=max-min) is calculated. Said differential value difference D is supplied to a comparator 10, and is compared with the threshold (th) previously set for a region discrimination. The comparator 10 outputs 1 which expresses that it is a character region, if the differential value difference D is larger than the threshold th, and on the contrary, if the difference D is smaller than the threshold (th), it outputs 0 as a decision signal.

Title: Smelting method for extremely low-sulfur steel
Inventor: KISHIGAMI KIMIHISA
IPC: C21C5/28
Filed: 1989-07-17
Abstract: PURPOSE:To smelt the extremely low-sulfur steel at the low cost of refractories and desulfurizing agent by stopping the oxygen blow to a molten iron at a specific C level, adding the desulfurizing agent to the molten iron to make a desulfurization treatment, then discharging slag, further adding a slag making agent for dephosphorization to the molten iron and blowing oxygen thereto. CONSTITUTION:The molten iron which is previously subjected to a desiliconization treatment is desulfurized and dephosphorized in a torpedo ladle car 1 by blowing CaO, CaF2, iron oxide, etc., from an immersion lance into the molten iron. This molten iron is then charged through a molten iron ladle 3 into a top and bottom blown converter 4. Cold iron material and the slag making agent are added into the molten iron and oxygen is blown via a top blowing lance 5 to make desiliconization and decarburization blowing. The supply of the oxygen is stopped in the stage of 0.3 to 2.5% C in the molten iron in this oxygen blowing. The desulfurizing agent is added from the top blowing lance 5 into the molten iron to forcibly desulfurize the molten iron to about 20 to 50ppm. The converter 4 is thereafter tilted to discharge desulfurizing slag 7 and the slag making agent for dephosphorization is added to the molten iron. The oxygen is then blown to this molten iron. The extremely low-sulfur steel is smelted by preventing resulfurization and accelerating the desulfurization reaction; in addition, the refining is executed in a short period of time and the cost is reduced.

CONSTITUTION:A vacuum preliminary chamber 51 is vented to atmosphere and products are put therein from a door 52; since a valve 53 is closed, rotation of a hydraulic rotary vacuum pump 54 is reduced by 50%. Thereafter the valve 53 is opened and a signal is fed via a sequencer 58 to an inverter circuit 59 from a sensor 56 which detects opening and closing of the valve. The number of revolution of the vacuum pump 54 is increased to a normal value by the circuit 59. Next, the valve 53 is closed, the number of revolution of the vacuum pump 54 is reduced by 50%, and a valve located between the chamber 51 and a high vacuum chamber 61 is opened to put the products in the high vacuum chamber 61. Since the number of revolution of the vacuum pump 54 is reduced by 50% unless necessary, the power consumption of the pump can be reduced.

Title: Medal shooting game machine
Inventor: TAJIMA SADAJI
IPC: A63F9/00
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To enhance interests of a game by a method a medal is shot toward a game section by striking the side of the medal to change the way of flying the medal so that forecasting the winning of the medal is made impossible. SOLUTION: A medal shooting rod 52 is urged normally in the direction of shooting by a power of an urging member 53 and is located at a shooting position being regulated by a rotation regulating member 56. Under such a condition, when a player manipulates an operation handle, a rotary member 54 is driven to rotate clockwise and a rotary plate 542 contacts a working protrusion 180 of a working piece 170, causing the medal shooting rod 52 to turn clockwise. As the shooting hummer 52 turns to the shooting preparation position, the working protrusion 180 deviates from the center of rotation of the rotary plate 542 and the contact between both 180 and 542 is released so that the medal shooting hammer 52 returns at a stroke to the shooting position by the urging member 53 and rotates.  Thus, a medal shooting part 51 hits the undersurface of a medal A held by a holding part 200 to shoot the medal A upward to a game section.
