摘要： PURPOSE:To make a recording of messages with high sound quality with a small amount of memory in the normal use and to deal with an occasional long-time message. CONSTITUTION:This automatic answering telephone set is provided with a mode A encoding section 7 and mode A decoding section 9 having the higher encoding bit rate, mode B encoding section 8 and mode B decoding section 10 having the lower encoding bit rate, message RAM2, and a system control section 1. The first half of the RAM2 is allocated to the storage location of the encoding data of the section 7 and the other to the storage location of encoding data of the section 8. The section 1 reads and writes the encoding data from the message RAM2 by switching the encoding section and decoding section based on the storage location of read and write.

摘要： PURPOSE:To locate sound in the middle in a front direction by outputting a sound retarded from a rear speaker by a difference signal between L and R and reproducing a monaural signal such as speech by an actor or a vocal especially from the front center. CONSTITUTION:The sum of electric signals L, R from a front central speaker 8C is formed at an L+R circuit of a synthesis section 2 and reproduced through a power amplifier 7L+R as a monaural signal of L+R. Since the monaural signal is the same in L and R, signals of L, R are cancelled by an L-R circuit of a comparison section 3, then no sound is reproduced from rear speakers 9L, 9R. In this case, the L and R signals are synthesized by the L+R circuit of the synthesis section 2 in the front center and reproduced from the front center speaker 8C. Thus, the sound located in the front center is obtained.

摘要： PURPOSE:To retrieve a corresponding graphic with a sentence and to retrieve a corresponding sentence with a graphic by allowing character codes and graphic numbers to correspond to each other. CONSTITUTION:Sentence data and graphic data are allowed to correspond to each other with respect to sentence data and graphic data inputted by an input means 203 or sentence data and graphic data stored in storage means 204 and 206. For example, a correspondence table between character code strings and graphic numbers is used or a table where codes indicating adverbs which limit ranges are gathered is used. Thus, a corresponding graphic is retrieved with the character code indicating the graphic number in sentences and the sentence corresponding to the graphic number is retrieved with a character code string.

摘要： PURPOSE:To move a cursor by a small number of times of a key operation even in a separated distance, by providing a key group which has been made to correspond to the moving direction of the cursor, and a key group which has been made to correspond to plural specified areas on a display. CONSTITUTION:When a ten key 30 is depressed in order to execute positioning of a macrocursor, movable positions of the cursor are displayed by + marks 11-19 on a display 30. Each + mark 11-19 corresponds to ten keys 21-29, respectively, and when the ten key 26 for showing the nearest position to an object position 20 is selected, a cursor 6 moves to a position of the + mark 16. Subsequently, when a ten key 32 is depressed in order to move the cursor to the target position 20, the + marks 11-19 are erased, a movement mode of the cursor becomes a relative position movement, and by moving the cursor 6 upward and downward, and to the right and left by ten keys 21-29, its movement to the object position 20 is ended.

摘要： PURPOSE:To reduce the noises produced when a power supply is switched on and off by detecting the variation of the power supply voltage in ON and OFF states of the power supply respectively and then applying the muting to an audio signal. CONSTITUTION:When an amplifier is kept on, a power supply switch 2 is set at the side B. Thus a relay 15 is turned on together with connection of a contact E-C. A transistor TR21 is actuated later than the relay 15 owing to the presence of a delay circuit consisting of a resistance 17 and a capacitor 19. When the TR21 is turned on, the base biases of muting TR6 and 7 are lost. Thus a muting state is released to prevent that the noises given to audio signals iN8 and 9 are mixed into speakers 11 and 12 when the amplifier is turned on. When the amplifier is turned off, the switch 2 is also turned off by a circuit consisting of resistances 23 and 24 and a capacitor 20. Thus the relay 15 is turned off after a TR22 is turned on.

摘要： PURPOSE:To facilitate the operations of a video device and the exchange of a tape, and make a tape-window visible externally by arranging the video device body at the glove box part of a dashpanel on the assistant seat side in a room. CONSTITUTION:A on-board video device 3, a television 4 for video, and a speaker 5 for video are arranged respectively at the glove box part 2 of a dashpanel 1 on the assistant seat in a room. Necessary apparatuses except the above apparatuses are arranged at places specially not specified such as an audio mounting part 6, etc. Thus, the glove box part 2 is in easy-to-reach place to facilitate the exchange of a tape. The operation of a control button can be made easier, and further a tape-window can be made visible externally.

摘要： PURPOSE:To attain the correction of the paragraph division in case of the division of the paragraph undergone the KANA (Japanese syllabary)/KANJI (Chinese character) conversion is different from that desired by an operator, by displaying plural appropriate candidates on a display device. CONSTITUTION:When a reading character string is supplied from a key input device 106, a processor 101 carries out the KANA/KANJI conversion and displays the converted character string at a text part of a display device 109. If an operator detects a part that is different from the desired result of conversion, an instruction for conversion is given to the different part. Then the processor 101 selects the most appropriate result of conversion out of a network memory 104 and displays it at the text part of the device 109. At the same time, the candidate of the paragraph with which the conversion is started is displayed in a candidate display area of the device 109. The operator selects the desired one of those displayed paragraph candidates and displays the most appropriate result of conversion at the text part of the device 109.

摘要： PURPOSE:To only indicate and change one code to automatically change all corresponding codes by providing a table where codes on a drawing and those in sentences are registered correspondingly to each other and linking codes on the drawing and those in sentences to each other. CONSTITUTION:This documentation device facilitates editing of a document including drawings and sentences through the mediation of codes on drawings and sentences explaining drawings, and sentences and patterns are stored in a document memory 203, and a table 204 is provided where codes on drawings and those in sentences are registered correspondingly to each other, and the table 204 is used to link codes written on drawings and those in sentences to each other. Thus, a code only in one position of the document is changed to automatically change the same code in the other positions of the document, thereby facilitating documentation.
