Abstract: PURPOSE:To obtain the subject roll having an outer layer which has excellent wear resistance by metallically bonding the outer layer and a shaft material by a casting and build-up welding method of pouring specific compsn. of the molten metal for the other layer to the circumference of the shaft material in a steel and welding them. CONSTITUTION:The molten metal 7 constituted, by weight, of 2.0-3.5% C, 0.3-2.0% Si, 0.3-1.5% Mn, <=0.1% P, <=0.08% S, <=2.0% Ni, >7-20% Cr, 3-10% Mo, 3-12% V and the balance consisting substantially of iron is refined. The molten metal 7 is poured to a void produced by inserting a shaft material 5 made of cast steel or forged steel into a mold in the same shaft in which a refractory frame 1, water-cooled mold 4, etc., are combined in the same shaft and is heated to stir by an induction heating coil 2. A closed member (not shown in Fig.) provided on the lower end of the shaft material 5 is then descended to start the solidification on the surface of said mold 4.

Title: Sheet producing apparatus
Inventor: KIMURA TOMOAKI
IPC: B22D11/18
Filed: 1979-05-25
Abstract: PURPOSE: To precisely control the thickness of the sheet produced by controlling the molten metal injection rate onto rotating drum surface from an upward nozzle in prompt response to the fluctuations of the gas pressure in the infurnace spacing on the molten metal corresponding to the fluctuations of the thickness.  
     CONSTITUTION: The molten metal 16 in a furnace 18 is spouted from an upward nozzle 26 onto the drum surface 14A under rotation and is cooled on the drum 14 to produce a sheet 30. In this case, a volume-changeable gas pressure chamber 34 communicated with the gas-pressure spacing 20 in the furnace 18 is provided and is so disposed that the volume of this chamber 34 is changed by the control command based on the thickness detection value of the sheet 30. Namely, the gas pressure in the spacing 20 is controlled by the volume change of the chamber 34, by which the injection rate of the molten metal 16 from the nozzle 26 is controlled. As a result of this, the pressure in the spacing 20 may be controlled rapidly in a prompt responsive manner when any thickness fluctuation occurs in the sheet 30. Hence, the thickness of the sheet 30 may be precisely controlled.

Title: Function generator
Inventor: SAITOU TSUTOMU
IPC: G06G7/26
Filed: 1987-03-20
Abstract: PURPOSE:To generate functions with optional accuracy by increasing the number of bits (n) of addresses in a ROM for recording the shape of an objective function. CONSTITUTION:The maximum value {f(x)}MAX and the minimum value {f(x)}MIN of a function f(x) are respectively assigned to the maximum address (2<n>-1) and address '0' and x-values corresponding to respective addresses are recorded in respective storing positions. Thereby, an AC signal 5 having a waveform corresponding to the recording contents of the ROM 3 and a fixed period T is obtained from the output of a DA converter 4. A comparator 7 compares the output signal 5 of the DA converter 4 with an input signal 6, outputs a signal 8 indicating '1' only when the input signal 6 is larger than the output of the DA converter 4 and indicating '0' in the other case. Since the signal 8 is modulated at its pulse width so that a mean value is proportional to f(x)-{f(x)}MIN, a fixed voltage signal 10 proportional to {f(x)}MIN is added to the signal 8 by an operational amplifier 9 and the added signal is smoothed to find out the mean value, so that the objective function f(x) can be obtained from the output of the amplifier 9.

Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce the degradation of a resolution by generating an intermediate image between the two frames that always continue and replacing the intermediate image with a skip video image when a skip phenomenon is generated. SOLUTION: A skip scene detection/compensation circuit 8 is inserted between a moving image decoder and a moving image compressor and the frame matching detector 14 of the skip scene detection/compensation circuit 8 compares the 1-frame delay output (1) of a frame delay device 12 with input signals (b) and outputs matching signals in the case that they are the same image. Then, in the case that a skip is generated, even through the matching signals are outputted for the output of the frame matching detector 14, the value of a motion vector detector 13 is kept at a normal value. Based on the result, in a skip scene detector 15, skip scene detection signals are outputted only in the case that the value of the motion vector detector 13 is within a detectable range and the matching signals are outputted.  As a result, a switch 17 is switched from (x) and (y) and the output signals of a frame interpolation device 16 are outputted from the terminal of the switch 17z.

Two incident light beams with different frequencies from each other are contracted to a window by a half mirror 2 and a lens 3 or a convergent type optical fiber bundle. the Raman oscillation and a Stokes' light frequency (omegaS1) is generated when the incident power density of an incident light frequency (omega01) is above the degree of 10<6>W/cm<2>. At this time, when omega02 is incident at the same time, the oscillation is generated at a lower threshold than that of omega02 alone to generate omegaS2. A resonator has little internal loss. That is, two generated Stokes' light beams reach higher field strengths than those corresponding to the respective incident power densities.
