Title: Production of caustic soda
Inventor: OOTA NOBUYUKI
IPC: C25B1/46
Filed: 1978-07-11
Abstract: PURPOSE:To produce NaOH through efficient and economical performance of diaphragm method electrolysis by refining salt water then preheating and electrolyzing the same and circulating the resultant H2 gas and Cl2 gas to preheating process. CONSTITUTION:Salt water 1 is supplied to a refining process 2, where it is refined. The refined salt water is sent through line 3 to a preheating process 4, where it is heat-exchanged with the H2 gas and Cl2 gase sent through lines 10, 9 from an electrolysis process 8 by heat exchangers 5', 5, whereby it is heated to the salt water 6 of high temperature. The salt water 6 is further heated to high temperature by a heater 7 using steam. This heated salt water is sent to the electrolysis process 8, where it is electrolyzed in an electrolytic cell and is taken out as Cl2 gas, H2 and caustic soda 11 containing edible salt. The edible salt is dissolved in the salt water which has been heated in the preheating process 4 and has been steam-heated, if necessary, to a high temperature to increase its concentration further, whereby the electric energy required for electrolysis in the electrolysis process 8 may be additionally reduced.

IPC: G11C11/414
Filed: 1990-03-30
Abstract: PURPOSE: To make it possible to rapidly charge and discharge the capacitance coupled to bit lines by using two pieces of current sources relatively small in a difference and using the larger current source for discharging the capacitance of the bit lines. CONSTITUTION: The bit lines B2, B4 are included. This pair is connected to row selection lines 24 which are connected to all the cells of columns 22 and particularly connected to the cells of the respective columns and the respective cells one of which exists at the rows. The respective columns and bit lines are selected and activated in order to select the prescribed cells for reading in the arbitrary given time. The capability to use a large current I2 for charging and discharging the capacitance of the emitter-base capacitance Ceb of transistors and the capacitance of the collector substrate capacitance CCS of the TRs shortens the reading out time of the cells. The input 26 of a sensing amplifier basically directly traces the bit lines and acts as a voltage follower to apply the rapid reading out of the relative voltages of the two TRs existing at the cells.  As a result, the rapid charging and discharging of the capacitors coupled to the bit lines are made possible.

Title: Tracking controller for recording/reproducing device
Inventor: MIHASHI YASUO
IPC: G11B5/588
Filed: 1989-04-03
Abstract: PURPOSE:To obtain a reproduced picture of the best quality by carrying out the tracking control so as to minimize the crosstalk envelope voltage value detected from the amplitude of the crosstalk signal component given from an adjacent track. CONSTITUTION:A crosstalk signal component detecting circuit 48 detects only the signal component of an adjacent track included in a demodulated chroma C signal. A crosstalk signal envelope detecting circuit 49 detects the amplitude of the crosstalk signal component. Then the envelope of the crosstalk signal component obtained from an adjacent track is detected, and the tracking control is carried out so that the digital signal of the crosstalk envelope is minimized. Thus the optimum position of a reproduction track can be traced so that the adjacent crosstalk signal component is minimized even though the signal is reproduced by a head wider than that used in a recording state. Then the video FM signals to be reproduced are sufficiently picked up and the pictures can be reproduced with high S/N and in a high grade.
