Title: Production of square steel tube
Inventor: TOYOOKA TAKAAKI
IPC: B21C37/15
Filed: 1994-05-20
Abstract: PURPOSE:To inexpensively reduce the deformation of a cut-edge of a square steel tube by applying bending to the correspondent circumference part of a round steel tube to be formed into respective sides of a steel tube from the inner surface side of tube so as to cause the compression strain on the outer surface side of the tube in the longitudinal direction of the tube in a stage of the round steel tube before the square steel tube forming process. CONSTITUTION:Two contact tips 12 are brought into contact with both edge parts of an open tube 1A formed in a round and the high frequency current is allowed to flow, the heated edges are pressure welded with a squeeze roll 13 and a round electro-resistance-welded tube is obtained. Weld bead is removed with a cutting tool 14. In a stage of the round steel tube 1B before the square forming process, to four correspondent circumference parts of the round steel tube 1B to be formed into four sides of a square steel tube 2, bending is executed from the inner surface side of the tube by four inner expanding rolls 21A to 21D. The square inner expanding rolls 21A to 21D execute bending so as to cause tensile strain on the outer surface side of the tube and compression strain on the inner surface side of the tube in the longitudinal direction of the round steel tube 1B. The inner expanding rolls 21A to 21D are attached pivotally in freely rotatable at the top end of a holder bar 15.

Abstract: PROBLEM TO BE SOLVED: To confirm play information other than identification information such as the number- of-times-of-non-start information or the number-of-times-of-probability fluctuation information even on a display screen of a special picture pattern display device visually confirmed at all times. SOLUTION: A number-of-times-of-non-start information display area 67 for displaying a graphic mark 66 as the number-of-times-of-non-start information at a position (on the right side, for example), which is not interfered with special picture patterns displayed while being varied inside special picture pattern display areas 63-65 of a variable display part (such as a liquid crystal panel 29, for example), is outputted/formed together with the special picture pattern display areas 63-65. Besides, a number-of-times-of-probability fluctuation information display area 69 for displaying a graphic mark 68 as the number-of-times-of- probability fluctuation information at a position (on the left side, for example), which is not interfered with the special picture patterns, is similarly outputted/formed together with the special picture pattern display areas 63-65.  Therefore, since the non-start information and the probability fluctuation information are displayed additionally to the special picture patterns as well, a player can recognize the non-start information and the probability fluctuation information as well by visually confirming the display screen and can be concentrated in the game. Further, the movement of a glance is comparatively reduced and especially, the fatigue of a person competing for a long time can be relaxed.

Filed: 1986-06-06
Abstract: PURPOSE:To make a long life of a furnace by a method wherein an air supplying operation is stopped in a desired time after a fuel supplying operation is stopped with a switch. CONSTITUTION:When a switch 11 is turned on in a heater 1, a solenoid valve 8s is opened, a fuel injection pump 6 and a fan 7 are operated, an ignition device or the like is operated and an ignition of injected fuel is started in a furnace 13. Along with this operation, a fan 16 is operated, air taken from within a green house is heated thereby an then the air is blown into the green house. Then, as a switch 11 is turned off, the fuel injection pump 6 is stopped, the solenoid value 87 is closed and then the fan 16 is also stopped. At this time, only the fan 7 continues to operate and is automatically stopped by a control unit 9 after a desired time is elapsed. In this way, after termination of the operation, it is possible to discharge ignited gas remaining in a combustion gas passage to discharge out of the device. Therefore, since the inner wall of the furnace or the like is not corroded with remaining combustion gas, the life of the furnace can be kept long.
