Filed: 1979-08-20
Abstract: PURPOSE:To obtain low cost of demagnetizing device, by rotating the demagnetizing coil through the provision of magnetic tape with metal reel in the demagnetizing coil. CONSTITUTION:After the support 11 of the carrier 10 is moved back to the arrow  C, the magnetic tape 7 with metal reel to be demagnetized is placed on the turntable 12. Next, the support 11 is extended toward the arrow C' and the tape 7 is  inserted to almost the center of the demagnetizing coil 20. With this state, the AC  magnetic field H of the demagnetizing coil 20 is in parallel with the orientation direction B-B' of the both sides 9a, 9b of the tape 9, and accordingly the part of the  both sides 9a, 9b is demagnetized. But, the front and rear parts 9c, 9d are not so  much demagnetized. Further, when the turntable 12 is turned by 90 deg., the front and rear parts 9c, 9d of the tape 9 are demagnetized. After a given time, the support 11  is moved back and the turntable 12 is picked up from the demagnetizing coil 20.

Filed: 1982-06-18
Abstract: PURPOSE:To perform automatically the reproduction and recording of only an optional part of a record with an inexpensive record player, by controlling the record player with a signal that detects the presence of a reproduced signal of the record player. CONSTITUTION:The number of pieces of music to be reproduced is previously set by means of a program switch 8 of a detecting circuit 6, then confirmed by a display 9. A detecting circuit 6 detects the presence of the music part of the reproduced signals and decides a soundless part as a soundless groove between a music and a music. When the play of the set number of musics is ends, a signal is delivered from a muting control output terminal 7 to actuate a muting circuit 3. Thus the output of reproduced sounds is inhibited. Then a signal is delivered from a record player control output terminal 10 to reset automatically the tone arm of a record player 12 to be controlled to the arm rest position. Then the music play is set in the over state or the tone arm is set in the cue state.

Title: Exposing device
Inventor: SAWAKI YUKICHI
IPC: G03B27/72
Filed: 1987-04-30
Abstract: PURPOSE:To stably reproduce an image by controlling temperature in the vicinity of an exposing board to absorb a change in the light quantity of a light source. CONSTITUTION:When an input voltage is dropped at the time of exposure, the light quantity of the light source 1 is reduced. The reduction of the light quantity is converted into a voltage by a photodiode 15 and the voltage is converted into a digital value by an A/D converter 17 to output the digital value to a CPU 18. At that time, the temperature of the exposing board 13 is kept at a certain value by controlling a heater 14 based on a command from the CPU 18. The CPU 18 computes the temperature of the heater 14 appropriate for supplying the reduction of the light quantity based on the improvement of the sensitivity of photosensitive/pressure sensitive paper, and in this case, controls the heater 14 to drop its temperature. When an input voltage is boosted, the heater 14 is controlled so as to be increased at its temperature. The change of light quantity is absorbed by changing the sensitivity of the photosensitive/ pressure sensitive paper, and even if an input voltage is changed at the time of exposure, stable image reproduction can be attained.
