Title: Pulse code modulation device
Inventor: KOBAYASHI MASAHARU
IPC: G11B20/10
Filed: 1983-08-24
Abstract: PURPOSE:To select simultaneous sampling or alternate sampling in each apparatus by adding also a signal for discriminating a sampling signal to a pulse code modulation (PCM) signal. CONSTITUTION:An input signal converted by an A/D converter 1 at a prescribed sampling time is converted by a sampling time converting circuit 21 and the converted signal is supplied to a signal processing circuit 51. The circuit 21 outputs a signal indicating a sampling time simultaneously to a control signal generating circuit 53 and a signal discriminating the simultaneous sampling or the alternate sampling and outputted from the circuit 53 is also added to a signal format formed by the circuit 51. Then, a PCM signal is outputted from a modulating circuit 52. At the reproducing of the PCM signal, a signal discriminating the sampling signal is extracted by a control signal extracting circuit 57 and a sampling time signal corresponding to the extracted signal is applied to a sampling time convertion circuit 21 in a reproducing system. Said constitution makes it possible to select the simultaneous sampling or the alternate sampling optionally in each apparatus such as a VTR for recording and reproducing the PCM signals.

Filed: 1985-07-15
Abstract: PURPOSE:To attain an input job with high efficiency by dividing an input area where information is supplied and defining the input given to a specific divided area as a KANA (Japanese syllabary)/KANJI (Chinese character) converting command. CONSTITUTION:A character writing frame 4 on a tablet 1 is divided into upper and lower parts, for example, and this upper part is defined as a specific area. When KANA characters written on the specific area by an input pen 2, this input to the specific area is defined as a KANA/KANJI converting command. In other words, a fact that characters supplied to the specific area are detected by a detecting circuit for characters to be recognized is processed as a KANA/ KANJI converting command. Then the conversion of KANJI is carried out based on said converting command. In such a way, the KANJI having a difficult order of strokes or complicated KANJI is converted automatically from the KANA characters written on the specific area. This improves the efficiency of input jobs.
