Title: Dephosphorization agent for hot metal
Inventor: ONO HITOSHI
IPC: C21C1/02
Filed: 1979-12-28
Abstract: PURPOSE:To provide an inexpensive, highly-effective dephosphorization agent for hot metal by mixing and baking two powder materials; one mainly consisting of CaO and the other mainly of SiO2. CONSTITUTION:To a powder material mainly consisting of CaO, such as quick lime powder, a powder material mainly consisting of SiO2 is added and mixed so that CaO/SiO2 molar ratio becomes 1.8-2.3. The mixture is baked at a temperature higher than 1,300 deg.C thereby preparing a dephosphorization agent for hot metal. This agent has composition of 2CaO.SiO2, a very high purity, and excellent dephosphorization capability. The powder material mainly consisting of SiO2 is a SiO2 mineral such as silica or silica sand, among which one with less than 20% of impurity is used under the baking condition described above.

Title: Reception circuit
Inventor: HARUHARA HIROSHI
IPC: H04B1/06
Filed: 1980-12-04
Abstract: PURPOSE:To increase the dynamic range of an input, by eliminating leakage of a local oscillation signal, through the provision of a diode at the post stage of a gate circuit which turns on/off the local oscillation signal. CONSTITUTION:An input signal Sin is picked up at a mixer 10 by a local oscillation signal Sl and outputted via a band pass filter 12. In such a reception circuit, the post stage of a gate circuit 14 is provided with a low-pass filter 16 and an attenuator 18 which attenuates the input signal, optimizes the local oscillation signal level and matches the impedance with the mixer 10. A diode 20 cutting off the leakage component of local oscillation signal from the gate circuit 14 is provided. Thus, if the local oscillation signal Sl includes leakage, when it is a contact potential or more of the diode 20, the leakage is cut off through the conduction of the diode 20.

Abstract: PURPOSE:To perform back-washing and exchanging of filter element during filtration by providing a working opening of specified structure. CONSTITUTION:When a partition wall 2 is rotated and one of element chambers 11 and one of the filter elements of their inner parts coincide with a back- washing water injection nozzle 15 and a back-washing water recovery nozzle 17 with their axes, the filter element 10, nozzles 15, 17 and the working opening 36 are so arranged as to be positioned almost the same axis, and both nozzle 15, 17 and the element chamber 11 are connected each other, but isolated from other spaces. And, as the inner diameters of nozzle 15, 17 and the working opening 36 are larger than the outer diameter of the filter element 10, the filter element 10 is allowed to be taken out or a new filter element 10 is allowed to be mounted through the working opening 36. Moreover, as the flow passage of back-washing water is independent from the working opening 36. The job of exchanging the filter element is easily carried out by the simple preparation of the stoppage of back-washing water and the removing of a plug 37 of the working opening 36.

IPC: G06F13/10
Filed: 1985-07-31
Abstract: PURPOSE:To attain an effective input/output control by securing a changeover between an input/output direct execution mode and an input/output simulation mode for an input/output instruction and an input/output interruption to an input/output device occupied by a virtual computer. CONSTITUTION:A signal is sent to an instruction register 4 when an operation system OSi delivers an input/output instruction executing request to the input/ output device 10-j of an input/output simulation mode. Then the register 4 sends the start signal of the corresponding instruction to an instruction executing circuit 5. The circuit 5 and an instruction executing program 6 check the input/ output direct execution mode bit of the corresponding input/output device field. The control is shifted to a virtual computer control program if said execution mode bit is equal to 0. When the system OSi delivers an input/output instruction executing request to the device 10-j of the input/output direct execution mode, a signal is sent to the register 4 together with the start signal of the corresponding instruction sent to the circuit 5. Here if the execution mode bit is equal to 1, the input/output instruction is directly executed through a signal line 103.

Abstract: PURPOSE:To minimize the effect of a calculation error of a computer and to apply linear prediction processing correctly regardless of the quantity of an input level by detecting part of an inputted voice data, using the voice data and realizing the evasion of overflow to be caused during prediction processing and the assurance of calculation accuracy. CONSTITUTION:The input voice is stored in a temporary buffer, some of the input voice signals are extracted, the minimum value and the mean value of the extracted input voice data are checked and a 1st correction means 23A predicts the deviation from the optimum level of the calculation processing guaranteed by a computer. Moreover, the deviation is multiplied with all voice data subject to buffering and overflow to be caused during the calculation of the predicting coding processing is detected by an overflow detection means 23C. In the case of the occurrence of overflow, a 2nd correction means 23B multiplies a weight coefficient with the voice data so as to compress the voice data near the mean value. Even if the voice signal of a low input level is inputted, the calculation accuracy is ensured and even if the voice signal of a high input level is inputted, no overflow is caused.
