Title: Rolling reduction method for cast slab of continuous casting and device therefor
Inventor: FUKUMOTO ICHIRO
IPC: B22D11/128
Filed: 1992-01-24
Abstract: PURPOSE:To prevent the internal crack by gradually increasing the interval of one pair of reciprocating rolls from a slab solidification completed point to the upstream direction along the drawing out line of the cast slab, reciprocating so as to gradually reduce from the upstream side toward the solidification completed point and repeating this reciprocation. CONSTITUTION:The cast slab W is drawn out of a mold in the condition of the solidified shell WS and the molten metal WL, and the part from the solid-liquid two phase zone to the solidification completed point in the drawing out line W of the cast slab W is sandwitched by one pair of the reciprocating rolls 10. The interval between one pair of the reciprocating rolls 10 is gradually increased from the slab solidification completed point in the attached figure W1 toward the upstream direction of the drawing out line along the drawing out line of the cast slab, and the reciprocation is executed so as to gradually decrease from the upstream side of the drawing out line toward the slab solidification completed point W1. By repeating this reciprocation, ironing rolling reduction is continuously executed to the part from the solid-liquid two phase zone of the cast slab to the slab solidification completed point. By this method, without causing the internal crack, the center segregation in the cast slab can surely be prevented.

Inventor: MORIURA YASUTOMO
IPC: H02M7/155
Filed: 1994-03-04
Abstract: PURPOSE:To prevent the extension of a fault damaging even a main circuit such as a thyristor converter, a breaker, etc., at the time of the fault of a controlled source by outputting gate pulses safely stopping a converter for an AC-DC converter without pulse-locking gate pulses applied to the converter when the fault of the controlled source is detected. CONSTITUTION:When a controlled source 51 for a converter controller 5 gets trouble and control voltage is lowered to the inoperative level of a control protective circuit 50, a phase control circuit 55 converts phase control pulses PHS into pulses stopping a converter 2 in the same manner as a start stop circuit 53 and a protective interlocking circuit 54 by a fault signal from a service interruption detector 100. The operation of an electronic circuit is ensured by a service interruption compensation circuit 101 for a period when a gate pulse controller 4 receives the phase control pulses PHS and the thyristor converter 2 is stopped by the gate pulse controller 4, and the control protective circuit 50 continues its operation. Accordingly, the pulse locking of gate pulses can be avoided, thus safely stopping an AC-DC converter.

Title: Sound recording amplifier circuit
Inventor: NAKAJIMA SHIGERU
IPC: G11B20/04
Filed: 1983-03-03
Abstract: PURPOSE:To vary frequency characteristics in ALC operation and to obtain sound recording characteristics in variety by connecting the output terminal of a power source with low output impedance to an input terminal of a comparator circuit through a resistance and the output terminal of a low-frequency amplifier circuit through a capacitor. CONSTITUTION:The output terminal 5 and an input terminal 7 are not connected directly, but connected through the capacitor C6; and frequency characteristics in ALC operation are varied to increase the degree of freedom of sound recording characteristics. Namely, the capacitor C6 is connected, so a signal inputted to the comparator circuit C is voltage-divided in cooperation with the resistance R58. This means that the signal voltage applied to the comparator circuit C varies with the frequency, and a signal exceeding the threshold voltage of the comparator circuit C decreases as the frequency becomes lower and lower to delay the start of the ALC operation, increasing the output voltage of a low-frequency amplifier circuit A. Therefore, the resistance R58 connected between the output terminal of the power source G with low output impedance and the input terminal 7 and the capacitor C6 connected between the output terminal 5 and input terminal 7 are varied in value to vary the frequency characteristics of the ALC operation freely.

Title: Transmittance variable spectacle lens
Inventor: NIWA TATSUO
IPC: G02C7/10
Filed: 1988-02-17
Abstract: PURPOSE:To obtain a transmittance variable spectacle lens which is densely colored in spite of a high ambient temp. and consumes less electric power in spite of long continuation of a colored state by forming the lens in such a manner that light transmits a lens base material, photochromic phase and electrochromic element irrespective of sequence. CONSTITUTION:This lens is constituted of the lens base material 1, the photochromic phase 2 and the electrochromic (EC) element 3. Since the EC element 3 utilizes the coloring accompanied with a readox reaction, the element is densely colored even if the ambient temp. increases. The photochromic phase 2 is capable of maintaining the colored state over a long period of time without a power supply as far as the strong sunlight falls thereon. Since the electrochromic 2 utilizes the coloration by a photochemical reaction, the coloring speed is substantially the same at the prescribed density even if the ambient temp. falls. The transmittance variable spectacle lens having the performance that the lens is densely colored in spite of the high ambient temp., consumes less electric power in spite of the long continuation of the colored state and maintains substantially the same coloring speed in spite of the lower ambient temp. is thereby obtd.
