Title: Inertia vibro-isolator with accelerator
Inventor: SAGOTA KATSUAKI
IPC: F16H25/20
Filed: 1982-07-28
Abstract: PURPOSE:To vary the vibro-isolating effect according to low or high rate of variation in the speed of displacement by converting linear motion into rotary motion by dint of a ball screw and mounting an inertia element on the shaft thereof via planetary gears. CONSTITUTION:In case displacement occurs at low acceleration because of thermal deformation or other reasons, a main case 1 and a sub-case 2 make relatively reciprocating motion in the axial direction so that a ball nut 3 turns a screw shaft 4. Planetary gears 6 then make revolution, slowly turning an internal gear 7 along with them. A sun gear 3 also turns, making a rotary shaft 9 turn together with an inertia element 10. In this case, an accelerator mechanism will not operate. In another case, where relative displacement occurs at a high acceleration because of earthquake or other reasons, the internal gear 7 cannot follow highly accelerated revolution of the planetary gear 6 due to the inertia force so that relative turn is produced between them. The planetary gear 6 tends to make the rotary shaft 9 make intense accelerated turn, however, cannot follow the turn because of the intertia of the inertia element 10. The inertia therefore acts as a great resistance against the turn to isolate vibration.

Abstract: PURPOSE:To perform a rapid and reliable measurement through a simple constitution, by measuring a load by means of a first force coil, whereto a current is applied corresponding to a load, and a second force coil which covers the shortage in the electromagnetic force of the first force coil. CONSTITUTION:If, with a subsidiary wound second force coil 3 actuated in conformity with a change in load, an A/D converter 7 overflows, a given reset value determined by a computing unit 14 is loaded to a preset counter 10 forming a second load evaluating part.

Filed: 1990-05-22
Abstract: PURPOSE:To enable bit selection at a real time by deciding the number of bits in ADPCM algorithm by using a differential signal, quantization differential signal from a bit decision circuit, or linear signals from an adaptive predicting device and a code conversion circuit. CONSTITUTION:In a code conversion circuit 2, code conversion is executed from an inputted PCM signal 1a to a linear signal 2a for a signal processing and the signal is outputted to a difference calculation circuit 3 and a bit number decision circuit 8. The difference calculation circuit 3 calculates difference between the linear signal 2a and apredict signal 7a to be outputted from an adaptive predicting device 7 and outputs a differential signal 3a to a quantizing circuit 4 and the bit number decision circuit 8. In the quantizing circuit 4, code conversion is executed from the differential signal 3a to an ADPCM 4a, and the signal is transmitted to an inverse quantizing circuit 6 and simultaneously outputted from an ADPCM signal output terminal 5 to the outside. Then, according to the integral value of the differential signal and a threshold value to be calculated from the input PCM signal, the number of bits is decided for the ADPCM encoding algorithm. Thus, the number of bits for ADPCM encoding can be selected in real time corresponding to an error signal.

Abstract: PURPOSE:To improve the quality of a continuously cast slab by quantifying thermal condition of refractory in a tundish from molten steel passing through quantity in the tundish and estimating temp. drop quantity in the molten steel during the time from tapping to arrival of the molten steel at the tundish under consideration of the above. CONSTITUTION:In the case of equalizing the conditions of charging weights of auxiliary raw material, ferro alloy and Al at the time of refining, time needed to the steel tapping, temp. of the ladle refractory, Ar bubbling time and lapse of time from the steel tapping to arrival at the tundish, the prescribed relation exists between the molten steel passing-through quantity in the tundish and the molten steel temp. drop quantity till the representative quantity in the tundish (the timing of pouring 45% of the molten steel in the ladle into the tundish). This accumulated heat quantity in the tundish refractory is increased as the molten steel passing-through quantity is increased, and as this result, it is considered that the temp. drop quantity in the molten steel becomes less. Then, the thermal condition of refractory in the tundish is quantified from the molten steel passing-through quantity in the tundish and under this consideration, the molten steel temp. at the time of steel tapping is controlled in the suitable range. By this method, the quantity of continuously cast slab is improved.
