Title: Casting method of clean steel
Inventor: NAKAJIMA JUNJI
IPC: B22D11/103
Filed: 1994-02-28
Abstract: PURPOSE:To suppress entrapment of slag layer by providing a slag breaker to a long nozzle, immersing the lower end of a long nozzle to the specific position and pouring. CONSTITUTION:The molten steel in a succeeding ladle 1 is supplied to a tundish in succession to a preceding ladle. Slag breakers 10, 11 are mounted to a long nozzle 13. At the timing that a slag breaker tube part 10 is melted, the lower end of the long nozzle 3 is positioned/immersed in >=30mm under a tundish molten metal surface 12 and then molten metal is poured. It takes 2-3min for the long nozzle 13 to be immersed >=30mm under the tundish molten metal surface 12, therefore a material of tube 10 is required not to be molted over 2min, and is required to slect an asbest, etc. For the purpose a slag is not penetrated in the tube 10, a thin iron sheet 11 of 0.3-2mm thickness is to be fitted to the lower end of the tube 10. It prevents increase of inclusion in cast slab due to knocking in of inclusion resulting from molten steel flow.

Inventor: MURAYAMA AKIRA
IPC: G01N29/24
Filed: 1991-03-18
Abstract: PURPOSE:To enable a defect to be detected with an approximately uniform sensitivity over a wide distance range in thickness direction by incorporating a plurality of division-type probes, having different focusing positions on a perpendicular to the surface for mounting a body to be measured, in one container. CONSTITUTION:Transmission vibrators 12a and 13a and reception vibrators 12b and 13b are placed at symmetrical positions sandwiching an acoustic division plate 14 within a box-type container 11 while being slanted nearly in chevron shape. Then, by setting a slant angle of a steel plate to be measured 4 of the vibrators 12a and 12b constituting a first division-type probe for a mounting surface 4a of the steel plate to be measured 4 to a value which is larger than an inclination angle of the vibrators 13a and 13b constituting a second division-type probe, thus enabling a focusing position 15 to be located closer to a mounting surface 4a than a focusing position 16. Therefore, by adjusting the inclination angle and enabling the focusing positions 15 and 16 of each probe to be distributed from a shallow position to a deep position near a bottom surface in perpendicular direction for the mounting surface 4a, a defect can be detected highly accurately with nearly a uniform sensitivity over a wide distance range including a short distance and a far distance in thickness direction within a steel plate 4.

Title: Method and apparatus for correcting shift in printing by printer
Inventor: TENKAI TAMIO
IPC: B41J9/50
Filed: 1983-03-29
Abstract: PURPOSE:To enable to widely compensate for a shift in printing, by a method wherein an excitation-starting timing is determined by a compensation time forming circuit comprising an approximate integrating circuit, and variations in flight time voltage are compensated for, in an impact-type line printer. CONSTITUTION:The velocity of a type belt 1 is obtained from a type passage signal obtained by a detector 5. Although types are moved by a predetermined distance in an operating period Tf from the moment of energizing each hammer 12 to the moment of printing, when a driving voltage VD varies, the operating period Tf is also varied, resulting in a stagger in printing position. Compensation time for the hammer flight time Tf under the variation of the driving voltage VD is equivalently obtained by the compensation time forming circuit 8 comprising the approximate integrating circuit, the excitation-starting timing based on the type passage signal obtained by the detector is formed by a circuit 9, and each hammer 12 is excited through a hammer drive controlling circuit 10 and a driver 11. Accordingly, the shift in printing can be compensated for in a wide range of variations in voltage.

Filed: 1987-03-10
Abstract: PURPOSE:To accurately measure the thickness of a surface layer even when the surface and border surface are irregular by projecting plural ultrasonic waves of different frequency on the same place of a laminar body and processing plural obtained echo data as specified. CONSTITUTION:An ultrasonic wave of 7-10MHz high frequency is transmitted first by a probe 1a and projected on the laminar body (not shown in figure) to be inspected, and its reflected ultrasonic wave is received and detected by a pulser receiver 7. Then a switch circuit 9 is driven under the command of a controller 9 and the ultrasonic wave is switched to the low frequency ultrasonic wave of 0.5-1MHz of a probe 1b, which is transmitted. Then its reflected wave is received by the receiver 7 similarly. Then a data processor 8 measures time from the high frequency detection signal to a surface echo and from the subtraction signal between both detection signals to a border surface echo to obtain the thickness of the surface layer from both times. Consequently, the thickness is accurately measured without reference to the irregularity of the surface and border surface.

Abstract: PROBLEM TO BE SOLVED: To automatically produce input time series including all state transitions of cache and input time series that generate many complicated competitions on a bus by performing depth priority search of state transition that is not calculated in the past within the range of preliminarily defined length and calculating a new input time series. SOLUTION: An inputting means 1 inputs description of a finite state machine. An achievable state generating means 2 finds an achievable state from an initial state and registers it. An input time series generating means 3 generates an input time series of the state transition from the initial state to an achievable state and registers it as a part input time series. A depth priority searching means 4 traces the path of the state transition from the initial state and from the achievable state to even further state and searches for depth priority. An input time series registering means 5 registers an input time series that is newly found by depth priority search. When all input time series up to the achievable state are found, an output device 8 outputs the found input time series.
