Title: Document conference system among many place
Inventor: MURAKAMI SHINICHI
IPC: H04L12/18
Filed: 1982-09-06
Abstract: PURPOSE:To attain a remote conference using documents among many places, by connecting three or more document conference terminals each other through a communication lines and making it possible to retrieve and display the same document picture in respective terminals. CONSTITUTION:When the user of a document conference terminal 120A inputs a retrieval document address from an operator 103, a control part 104 retrieves a corresponding document from a document file part 102, draw out the retrieved document to a refresh memory part 105 and displays the document in a display part 106. Simultaneously, the retrieved information is inputted to an exchange device 200 through a communication line 107A. An intra-multipoint document conference processor 201 receives the retrieval information at a signal transmitting/receiving part and sends the received information to a signal processing part through a signal line. The signal processing part sends the received signal to all signal transmitting/receiving parts excluding the signal transmitting/receiving part from which the signal is received through a signal line. These retrieved information is sent to respective document conference terminals 120B, 120C through respective communication lines. Each terminal takes out the document from the document file and displays a display part 106.

Title: Production of 4,4'-dihydroxydiphenyl sulfone
Inventor: WATANABE YOSHIAKI
IPC: C07C313/00
Filed: 1984-07-27
Abstract: PURPOSE:To obtain the titled compound in high purity and yield in a short process, by distilling away formed water in an amount within a specific range of the theoretical amount, adding a phenolic compound thereto, and reacting the phenol with sulfuric acid under heating at a specific temperature while distilling away the excess amount of the phenol. CONSTITUTION:Phenol is mixed and thermally reacted with sulfuric acid. In the process, formed water in an amount of 75% or more of the theoretical amount thereof is distilled away, and phenol is added to the reaction mixture. The reaction mixture is heated at 140-200 deg.C while distilling away the excess amount of the phenol to give the aimed 4,4'-dihydroxydiphenyl sulfone. The ratio of 2,4'- dihydroxydiphenyl sulfone in the reaction mixture is reduced, and the ratio of the 4,4'-dihydroxydiphenyl sulfone is increased depending on the reaction conditions. The reason why the reaction is completed in a short time is that the intermolecular isomerization reaction expressed by the reaction formula (rings A-C are separate aromatic rings) between the 2,4'-dihydroxydiphenyl sulfone and the phenol seems likely to occur.

Title: Semiconductor memory
Inventor: YAMAGUCHI SEIJI
IPC: G11C11/34
Filed: 1987-06-23
Abstract: PURPOSE: To shorten the test time of a functional test of a memory system by providing a function for testing the error correcting function of a memory system on a semiconductor memory chip.  
     CONSTITUTION: When the error correcting function is tested, signals EG0 and EG7 are used as testing signals to generate errors in corresponding bits. At this time, a semiconductor memory Mi where a signal EGi (i=0...7) is set inverts the logical polarity of read data and outputs the data, so erroneous data is transferred to a data bus Di. Thus, the error correcting function is tested simultaneously with a normal test, so the test of the error correcting function need not be provided.
