摘要： PROBLEM TO BE SOLVED: To obtain a flame retardant polycarbonate resin composition, realizing flame retardancy without noxious gas generation when burnd and also capable of giving a molded product having good optical transparency by including an organopolysiloxane having a specified structure into an aromatic polycarbonate resin. SOLUTION: This composition comprises (a) 100 pts.wt. aromatic polycarbonate resin and (b) 1-10 pts.wt. organopolysiloxane including 50-90 mol.% siloxane unit represented by R .SiO3/2 , 10-50 mol.% siloxane unit represented by R R .SiO2/2 and >=80 mol.% phenyl group based on the total organic substituents R , R and R in the above formulas are each a 1-10C nonsubstituted or substituted monovalent hydrocarbon group).

摘要： PURPOSE:To read out the contents of an original to be transmitted only with the depression of a designating key and to transmit the contents of required items with a facsimile by registering the original as a format in an equipment relating to a user who usually transmits the same original almost everyday in the case of the normal use and using ten keys or a keyboard to record only required items. CONSTITUTION:A control panel 1 is provided with a format designating key 2 and format contents are displayed on a display device 3 at the time of depression of the key and namerals, KANJI (Chinese character), etc., can be inputted to the contents by ten keys 4 or an external keyboard and a control circuit 5 performs such control that the contents are taken out from a storage circuit 7 for format storage and a character generator 9 for KANJI and are synthesized in a memory 8 for synthesis to transmit a picture from a transmission control part 10 to a communication channel.

摘要： PURPOSE:To obtain a reproduced picture having its contrast corrected optionally by preparing plural types of gradation characteristic curve data and designating a level range of said data for production of the gradation correction data. CONSTITUTION:A CPU 13 of a gradation correcting part 1 reads the designated gradation characteristic data out of a ROM11 based on a selection instruction to store the data into a RAM12 and also to transfer it to a control part 3. Then the CPU13 produces the gradation correction data from the data on a gradation characteristic curve in accordance with a correcting level range included in the selection instruction received from the part 3. In other words, the CPU13 performs an arithmetic operation to change an input level range (a) of a gradation characteristic curve A into a designated level range (b). Then the obtained output level data on a gradation correcting curve B corresponding to the curve A is stored in the RAM12 and at the same time sent to the part 3. The part 3 gives both input and output levels of the gradation correction data to a display part 4 to show them in the image forms. Thus the correction picture data 15 of corrected multi-gradation is obtained.

摘要： PURPOSE:To attain a call between an opposite party during call and other telephone set without using a function of an exchange by providing a microphone and a speaker opposite respectively to a speaker and the microphone of a handset of a telephone set when the handset of the telephone set is coupled. CONSTITUTION:When an extension telephone set of this connector is desired to be communicated with a line wire while a telephone set A is busy with the line wire, other telephone set B than the telephone set A during call makes an extension call and each handset of the two telephone sets A, B is set to the connector 1. Thus, the calling parties of the two sets of telephone sets A, B are communicated via the connector.
