Then the calculation result of the fludization analysis is output to an intermediate file 5. Therein a predictive index during a packing process of resin is calculated by using a prescribed burning prediction expression. In other words, the maximum value of the temp. of resin for the respective elements within a time wherein resin is packed into a mold is obtained at every element. Generation of burning is decided by comparing this maximum value with the prescribed temp. of resin.

IPC: H03M1/36
Filed: 1981-03-30
Abstract: PURPOSE:To suppress the noise of a sampling pulse source mixed into a digital output signal by integrating a parallel processing type A/D converter by adding a frequency dividing circuit which divides an A/D conversion pulse from the sampling pulse source by N. CONSTITUTION:When the frequency of a sampling pulse source connecting with the A/D conversion pulse input terminal 12 of a parallel processing type A/D converter is NfS and phase noise power spectrum density S (f), the output frequency of an integrated N-frequency-dividing circuit 18 is fs and its noise spectrum density is S (f)/N. Pulses with the frequency fS are applied to a comparator group 15 to sample an analog input signal Vin. During the sampling, a noise from the sampling pulse source is added to the signal Vin, but its level is S (f)/ N, thereby suppressing the mixing of the noise into the signal Vin to 1/N.

Abstract: PURPOSE:To sufficiently respond to rapid variations in steam load and as well to respond even to abrupt decreases in the demand of steam load on the process side without a large amount of air being discharged, by precedingly controlling a waste heat recovering boiler bypass damper and a waste heat recovering boiler output damper in accordance with a variation rate in the flow of steam. CONSTITUTION:An abruput variation in steam load is detected by a steam flow detector 19 to obtain a flow variation rate DELTAQ/DELTAt. Thereby, the damper opening degrees of a waste heat recovering boiler bypass damper 6 and a waste heat recovering boiler output damper 7 are obtained by means of function generators 20, 21 so that the dampers are controlled in accordance with signals from the function generators 20, 21 to rapidly follow up the abrupt variation. When the pressure of steam comes to be stable, selectors 22, 23 select signals obtained under pressure control during normal operation, and cuts off a steam load abrupt follow-up signal. Normally a function generator 9 receives a steam pressure 8 and issues a split control signal for the bypass damper 6 and the output damper 7, and subtracters 10, 12 obtain the differences between the signals and the opening degrees 14, 15 of the dampers, and deliver signals 16, 17 to the dampers through proportional integrators 11, 13.

Filed: 1982-03-25
Abstract: PURPOSE:To prevent adverse effect when a cathode can is shrink-fitted to an anode can, and increase capacity and leakage resistance by placing a low heat conductive metal plate between a cathode can and a cathode active mass. CONSTITUTION:A figure 12 shows a low heat conductive metal plate comprising stailess steel or nichrome, which is placed between an upper surface 8a of a cathode can 8 and a cathode active mass. When the cathode can 8 is shrink- fitted to a negative canl, internal shortage must be prevented. If the low heat conductive metal plate 12 is not placed in between, the cathode can 8 is directly in contact with the cathode active mass. When the low heat conductive metal plate is placed in between, since heat from the cathode can 8 during shrink fit is transmitted to the low heat conductive metal plate 12, then transmitted to the cathode active mass, the cathode can is fitted before the heat is transmitted to the cathode active mass. By immediately cooling the cathode can 8, it is shrink- fitted without giving adverse effect to the cathode active mass.
