Title: Assembly of data group of digital audio tape
Inventor: ROBAATO SHII RITSUCHIMONDO
IPC: G11B20/12
Filed: 1990-07-12
Abstract: PURPOSE: To simplify buffer management by transferring each frame read from a tape directly to the correct storage location of group buffer based on subcode information. CONSTITUTION: An address bus 13 and a random access memory connected to a data bus 15 are utilized by a microprocessor 11 for data group buffering or other memory functions. The output of a demodulator 19 is processed by a decoder 21 to disintegrate the demodulated data into frame information and subcode information. And a processor 23 which responds to the subcode information checks the validity of the subcode information and determines the storage location of the address group of the corresponding frame data; and a parallel- serial conversion circuit 25 transfers the frame data to the address group memory location, the RAM 12. By this, buffer management is simplified.

Abstract: PURPOSE:To carry out continuous manufacture of high-purity metallic Ti in high yield, by performing an undermentioned reaction by controlling pressure in a reactor and then by separating Ti by specific gravity difference at the time of manufacturing Ti by allowing TiCl4 to react with a metal as a reducing agent. CONSTITUTION:A Ti ingot 16 is held in the bottom of a reactor 1, and MgCl2 17 is charged onto the ingot 16, and then, an electromagnetic induction heating coil 8 is electrified to melt an ingot top 16a and the MgCl2 17. Subsequently, a temp. in the vicinity of the surface of the MgCl2 bath 17 is raised up to a temp. suitable for reaction, and the internal pressure of the reactor 1 is pressurized by means of an inert gas until a pressure of the sum total of respective vapor pressures of Mg and MgCl2 at the temp. in the vicinity of the bath 17 surface of above is reached. Then, when liquid TiCl4 and molten metallic Mg are supplied from pipes 13, 14, respectively, into the bath 17, these mutually react in the vicinity of the bath 17 surface, by which solid metallic Ti and molten MgCl2 as a by-product are formed. Since the above metallic Ti is deposited in the form of Ti lumps 16b on the top 16a, these Ti lumps 16b are continuously drawn out in the form of a Ti ingot while being subjected to physical property control.

Title: Electrolyte for lithium secondary battery
Inventor: TOBISHIMA SHINICHI
IPC: H01M10/052
Filed: 1987-07-24
Abstract: PURPOSE:To increase the charge-discharge performance of a lithium electrode by using at least lithium 7,7,8,8-tetracyanoquinodimethanide as a lithium salt in an electrolyte. CONSTITUTION:An electrolyte containing at least lithium 7,7,8,8- tetracyanoquinodimethanide as a lithium salt is used. By using this electrolyte, a protection film is formed on the surface of deposited lithium to retard the reaction of the deposited lithium with a solvent which causes a deterioration in charge discharge efficiency of a lithium electrode. Since the lithium 7,7,8,8- tetracyanoquinodimethanide is used for forming the protection film on the surface of lithium, the addition of a small amount of this salt in the electrolyte having usual solute and solvent shows enough effect. The charge-discharge performance of a lithium electrode is therefore improved.

Abstract: PURPOSE:To accurately perform a collating operation after no-paper interruption by returning a bin to its home position synchronously with the start-up of a single signal indicating the image forming operation of an image forming device and continuing to send this signal even when no paper is left. CONSTITUTION:The image forming operation of the specified number of sheets via an image forming means (c) is started by the depression of the start key (b) of an image forming device (a), and a signal SI0 indicating this operation is fed to the control means (f) of a sorter (e) from the image forming means (c).

Abstract: PURPOSE:To accelerate the signal output of the device by providing a control means to apply a high potential or a low potential after applying a specified potential between the low and high potentials which are internally decided to an output signal line, when applying the high or low potential to the output signal line. CONSTITUTION:When an output signal line 4 is set at the high (low) potential, a control means 1 applies the specified potential between the high and low potentials before outputting the low (high) potential to this output signal line 4. Therefore, potential difference to be canceled in the case of the signal output is reduced and the output of the low (high) potential to the output signal line 4 is prevented from being delayed. Thus, the signal output can be executed at high speed.
