Title: Lance tube support structure of soot blower
Inventor: ITANI HIKOTAROU
IPC: F23J3/00
Filed: 1982-04-28
Abstract: PURPOSE:To prevent unreasonable force from being applied between a lance tube and its support structure and also prevent them from being worn and damaged by supporting a cage provided with a roller for supporting the lance tube in a manner of freely reciprocating in the axial direction. CONSTITUTION:A circular tube 40 for supporting a lance tube 7 on its inner side, and the upper ends of cages 43 and 44 having rollers 41 and 42, respectively for supporting these cages, are fixed to an upper plate 49. A roller 45 and the like are provided on support plates 54 and 55 mounted on a channel beam 1, and the upper plate 49 is moved on the roller 45 to move the cages 43 and 44 frontward and rearward in the axial direction of the lance tube 7 in a range between a front wall 52 and a rear wall 53 and the movement in the direction rectangular with respect to the shaft is determined by stoppers 56 and 57. As a result, unreasonable force due to wear and vibration caused by slides is not applied to the lance tube 7 and the lance tube support 9 such as the circular tube 40. Therefore, the durability of the support structure can be prolonged and the cost thereof can be lowered.

Title: Observing method for linearity of television deflection current waveform
Inventor: NIIHORI YOSHIZOU
IPC: H04N17/04
Filed: 1980-05-27
Abstract: PURPOSE:To observe the gradient of a waveform in a constant small period continuously by delaying a deflection current waveform, observed through an oscilloscope, by a certain time and then by comparing it with the original signal waveform. CONSTITUTION:A signal (a) of a television deflecting current is passed through a signal delay device 1 to obtain a similar waveform signal (b) with a phase lag. The signals (a) and (b) are inputted to a differential amplifier 2 to obtain a difference signal between the signals (a) and (b). This difference signal is projected on an oscilloscope 5 via a switch 4. On the other hand, a synchronizing pulse or oscillation pulse (c) is inputted to a pulse stretcher 3 to obtain a pulse (d) with stretched pulse width, which is inputted to the switch 4. The switch 4 connects the oscilloscope 5 to the output of the amplifier 2 when the signals (a) and (b) are both in scanning periods and grounds the input of the oscilloscope 5 from the flyback time of the signal (a) to the completion of the flyback time of the signal (b). From a thus obtained signal (e), the linearity of a deflecting current waveform is observed.

Title: Continuous casting method for thin sheet
Inventor: YAMAMOTO KEIICHI
IPC: B22D11/20
Filed: 1985-04-05
Abstract: PURPOSE:To make easy the starting of casting and the restarting of casting after breakout by bringing drums into tight contact with each other prior to the start of casting then opening the space between the drums at a specified speed and adjusting the rotating speed of the drums upon starting of pouring. CONSTITUTION:The space between one water-cooled casting drum 1'' and the other water-cooled casting drum 1 is adjusted by an oil pressure, etc. The space quantity is measured by a sensor 15 and the measured displacement quantity is converted to an electric signal by a displacement converter 12. The relation between the space quantity and the displacement is controlled by a controller 13. The output is outputted by an output amplifier 14 and a driving source 10 is operated to control the rotation of the drums 1, 1''. The molten metal is therefore poured at a specified flow rate from a tundish and at the same time the drums open from the initial tight contact state and rotate to provide the prescribed space and rotating speed. The mass-balance with the molten metal supplied thereto is thus attained. The need for mounting a dummy bar to be used in the initial period is thereby eliminated and the recasting after the breakout is made possible.

Title: Voltage controlled oscillation circuit
Inventor: FUJIWARA MASAO
IPC: H03K3/0231
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a 1/2 frequency-dividing circuit, which is required for securing 50% of a duty ratio, and to prevent jitter from deteriorating by setting the duty ratio to be 50% at the stage of source oscillation without depending on an oscillation frequency. SOLUTION: When the signal at a high level is outputted from a buffer 18, a switching element 15 grounds the gate of the MOSFET 16 and a switching element 19 inputs reference voltage VA to the terminal (+) of a comparator 17. The MOSFET 16 is turned off and a capacitor 14 is charged. When the voltage of the capacitor 14 becomes higher than reference voltage VA, the signal at the low level is outputted from the comparator 17 and the signal at the low level is outputted from the buffer 18. Furthermore, the switching element 15 is grounded to the gate of the MOSFET 11 and the switching element 19 inputs reference voltage VB to the terminal (+) of the comparator 17. Thus, both periods of the high and low levels become equal and the duty ratio becomes 50%.
