Title: Plugging sand for ladle steel tapping hole
Inventor: FURUNO YOSHIKATSU
IPC: B22D41/46
Filed: 1987-08-13
Abstract: PURPOSE:To drastically improve natural opening hole ratio and to drastically reduce trouble in the operation by specifying composition of sand for plugging in a ladle steel tapping hole. CONSTITUTION:The ladle 11 is lined with refractory 12 and outside of the refractory is covered by iron plate 13. Molten steel 14 is stored in the ladle 11 and the molten steel tapping hole 16 is formed at the bottom part. An upper nozzle 15 made of refractory is arranged around the tapping hole 16 and below this, a sliding nozzle 20 is fitted. The nozzle provides a fixed plate 21 fixed at lower end of the upper nozzle 15 and a sliding plate 22 slidably arranged below the fixed plate 21, and by shifting the sliding plate 22 toward the arrow mark 24 direction, the tapping hole 16 is opened/closed. In this case, as the sand 31 has the composition of >=98wt.% SiO2 and <1wt.% alkali oxide, it is difficult to fuse and bridging is difficult to form. Therefore, in the case of opening the steel tapping hole 16 by sliding the sliding plate 22, the sand 31 is quickly flowed out and the natural opening hole ratio is improved.

Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a DC control circuit which can supply the stable DC voltage to the outside without effected by the temperature characteristics of current sources and also can optionally set the control sensitivity of the DC voltage. SOLUTION: A voltage generation part 4 takes out the difference currents between the currents I3 and I4 which are generated by the current sources IR3 and IR4 of the current generating part 3 and the currents ICUR2 and ICUR3 of the current mirror circuits CUR2 and CUR3 which are generated according to the base voltage of the transistors Q3 and Q4 , converts those difference currents into the voltage via a resistance element RT4 , and adds this voltage to the voltage V5 of a constant voltage source VR5 which generates the offset voltage to output these added voltage to an output terminal TOUT. Thereby, the effects of temperature characteristics of both sources IR3 and IR4 are cancelld with each other and the stable DC voltage can be supplied without giving any effect of the temperature characteristic to the output voltage VOUT of the terminal TOUT.

Title: Automatic frequency control circuit
Inventor: CHIHARA TAKAHIRO
IPC: H03L7/06
Filed: 1989-08-04
Abstract: PURPOSE:To exclude the effect onto a demodulation characteristic due to a temperature change without need of an exclusive reference crystal oscillator by providing a phase comparator using an oscillated output from a voltage controlled crystal oscillator used at a clock recovery section of a demodulation circuit as a reference frequency. CONSTITUTION:An oscillated output of a voltage controlled crystal oscillator (VCXO) 12 used in a PLL of a clock recovery section 11 recovering a clock for demodulating an MSK (Minimum Shift Keying) signal from the standpoint of frequency stability is used for a reference frequency of a phase comparator 8. Then the PLL of the clock recovery section 11 follows the clock at the sender side with highly stable state when the clock is recovered. Thus, no exclusive reference oscillator is required and the frequency stability of the recovered clock is equal to that at the sender side and the effect due to temperature change is not affected.

Filed: 1988-08-17
Abstract: PURPOSE:To perform the fault diagnoses in a simple constitution by reading the data out of another magnetic disk when a read error occurs and deciding a magnetic disk having the read error based on the data reading result as a hard fault. CONSTITUTION:A microprogram control circuit 120 drives a data transfer circuit 110 via a line 203 when an instruction is received from a CPU (not shown in a diagram) via a line 202 for read/diagnosis of data. In the case the occurrence of a read error is detected while the data are read out of a magnetic disk device (not shown in the diagram), the circuit 110 is driven via the line 203 and the data are read out of a magnetic disk (not shown in the diagram) different from the disk having the read error via a line 201. Thus a fault of the former magnetic disk is decided and reported to the CPU in the case no error is detected from the data which are read out of the latter magnetic disk.

Abstract: PURPOSE:To form a MIS capacitor whose parasitic resistance on its side toward the semiconductor substrate is reduced by providing at least two electrodes on that side. CONSTITUTION:A MIS capacitor is constituted with an n-type Si layer 2, an insulating film 4, and an Al electrode 5, and Al electrodes 6a and 6b are provided on the n-type Si layer 2, an insulating film 4, and an Al electrode 5, and Al electrodes 6a and 6b are provided on the n-type Si layer 2 at the opening sections 3a and 3c of an insulating film 5. When a parallel resonance circuit is formed by a MIS capacitor having a MIS capacitor C of 10pF and a coil having an inductance L of 15.8nH, its resonance frequency is represented by the formula. When the Q-value of a MIS capacitor is calculated supposing that the resistance of the Al electrode is 30mOMEGA and the semiconductor-side parasitic resistance is 10mOMEGA, Q=10 is obtained. If the parasitic resistance is represented by R, and a resonance angular frequency is represented by omega0 (=2pif0), a relation formula Q=1/omega0CR is satisfied, and R=4OMEGA is obtained. If these are calculated in the same shape about a MIS capacitor in a former semiconductor device, Q=4.2 and R=9.5OMEGA are obtained. It becomes possible to reduce the parasitic resistance compared to former ones.
