Title: Input buffer circuit of semiconductor memory
Inventor: BOKU SHIYOUKUN
IPC: H03K19/00
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To improve a margin in a high input range and the one in a low input range by making a logical threshold voltage lower when an external voltage level is high and by making it higher when the external voltage level is low. SOLUTION: A signal LVCC comes to be in a high state when a first external voltage divided in a prescribed ratio is a reference voltage or below and to be in a low state when it is the reference voltage or above. An external voltage sensing part 100 outputs this signal and a signal HVCC which comes to be in the high state when a second external voltage divided in the prescribed ratio is the reference value or below and to be in the low state when it is the reference value or above. A buffer 200 converts an input signal of a TTL level into a signal of a CMOS level on the basis of the output signals HVCC and LVCC of the external voltage sensing part 100. According to this configuration, a margin in a high input range and the one in a low input range are improved.

Patent JP-S5496914-A (JP)
Title: Automatic frequency control system
Inventor: INAGAKI AKIHISA
IPC: H04J1/06
Filed: 1978-01-18
Abstract: PURPOSE:To increase the frequency division multiple communication system by preventing the transmission frequency from a slave station from disturbing at least the communication of other slave stations in case the detection of the synchronous signal is impossible through the synchronous signal monitor circuit. CONSTITUTION:The slave station gives the sweep change and catch the frequency of the local oscillation frequency to the synchronous signal transmitted from the master station. And in case the synhcronization is obtained, the synchronous signals are detected through synchronous signal monitor circuit 14 and 27 to close switch 15 and 28. While in case no synchronous signal is detected, the sweep changing is discontinued for the frequency of the local oscillation signal. Thus, the frequency of the local oscillation frequency which gives the subordinate control to the transmission frequency is oscillated freely within the frequency region allotted to the slave station so that the frequency of the transmission signal from the slave station may be prevented from disturbing at least the communication of other slave stations. As a result, such fault in that the step-out of one slave station disturbs the communication of other stations can be prevented, thus enhancing the reliability for the frequency division multiple communication system.

Title: Separation of sulfuric acid from reaction mixture of beckmann rearrangement
Inventor: YOSHIHARA HIDEO
IPC: B01D61/24
Filed: 1981-01-16
Abstract: PURPOSE: In separating sulfuric acid from a reaction mixture of Beckmenn rearrangement by diffusion dialysis, to enable the sufficient recovery of dialysis efficiency without requiring the disjointing operation of a dialysis bath, by bringing periodically a  dialysis membrane into contact with sulfuric acid with a specific concentration.   
     CONSTITUTION: If necessary, a reaction mixture of Beckmann rearrangement is diluted with water, the fulfuric acid concentration in the mixture is adjusted to 60W90wt%,  and the mixuture is brought into contact with water through a dialysis membrane in  counter current flow, so that sulfuric acid is separated from the mixture. The dialysis  conditions are preferably set in such a way that the concentration of sufuric acid of  the dialyzate solution is 25W35wt% and the concentration of slufuric acid of diffused  solution is 25W40wt% when the dialysis ratio is 50W70%. Every time the dialysis ratio of sulfuric acid is lowered to the set value, the dialysis membrane is brought into contact with sulfuric acid having a concentration of ≥30wt%, and impurities attached to  the dialysis membrane are dissolved and removed. By bringing the reaction mixture of the rearrangement previously with active carbon to remove the impurities through  adsorption (the content is lowered to ≤100ppm), the attachment and accumulation of  the impurities to the dialysis membrane are extremely suppressed.

Title: Pretreatment of molten iron
Inventor: SHINOHARA KOICHI
IPC: C21C1/04
Filed: 1987-01-13
Abstract: PURPOSE:To permit efficient desiliconization of molten iron by a fine powder desiliconizing agent by forming the fine powdery desiliconizing agent into pseudo particles by water or steam to increase the sp. gr. thereof at the time of subjecting the molten iron from a blast furnace to predesiliconizing and refining by using said fine powdery desilizonizing agent. CONSTITUTION:Desiliconization and prerefining of the molten iron 10 tapped from the blast furnace are executed by feeding the fine powdery desiliconizing agent 14 from a charging tank 1 to a charging lance 2 via a piping 3 and blowing the same into the molten iron 10 in an inclined pouring trough 7 in a stage for separating the molten iron 100 from molten slag in a molten iron trough 6, then housing the same into a molten iron carrying container 8 via the trough 7. The desiliconizing agent is in the fine powder state and has extremely small bulk sp. gr. in this case and, therefore, said agent hardly enters the inside of the molten iron 10 and stays on the surface of the molten iron. The desiliconization effect is extremely poor in such a case. The steam or water is, consequently, added in the form of mists at 0.5-5wt.% to the fine powdery desilizonizing agent 14 by a spray tip 13 in the upper position of the lance 2 to wet the agent and to form the pseudo particles 12 thereof by which the sp. gr. of the agent is increased. the desiliconizing agent is thereby infiltered deep into the molten iron 10 to effectively desiliconize the molten iron. The low Si molten iron 10 and desiliconized slag 9 are then put into the molten iron transporting container 8.

IPC: H03J7/18
Filed: 1984-01-11
Abstract: PURPOSE:To eliminate loss of search time by starting the next search from a selection receivng frequency at start of the automatic search mode so as to store easily the reception frequency from high to low frequencies sequentially. CONSTITUTION:The content of a memory circuit of a channel designated at present is written automatically in a sub-memory circuit 6 just after the automatic search mode is started or the mode is stored newly. In case of the branch where a new channel is designated and searched again, when an idle channel is designated, the sweeping is started from the reception frequency of the channel designated precedingly at the search by writig the content of the circuit 6 to the circuit of the designated idle channel. Thus, even if the reception frequency stored newly is slightly lower than the reception frequency previously stored, the search is performed without consuming much time.

Abstract: PURPOSE:To make it possible to perform D/A conversion quickly with a simple constitution, by controlling current source switch cells arranged in a matrix by signal groups from the 1st, 2nd and 3rd encode circuits. CONSTITUTION:Encode circuit 2 generates 8 pieces of encode signal groups of A0-A7 from the highest 3 bits of digital input, and encode circuit 3 encodes further signals A0-A7 and generates encode signal groups B0-B7 and then sends signals corresponding to each current source switch cell in the same line, respectively. On the other hand, encode circuit 4 generates 8 pieces of encode signal  groups of C0-C7 from the lowest 3 bits, and supplies corresponding signals C0-C7  to each current source switch cell of the same row. Then the current source switch  cells arranged in a matrix are controlled by signal groups from these encode circuits, and thus the current output is obtained. By this, D/A conversion can be made  quickly with such simple constitution.
