  • Patent number: 4318110
    Abstract: In a multi-channel recording instrument, the reference signal of each channel is floating from the ground level. Therefore, one each isolated power supply means must be provided for each channel. However, when the error signal for each channel is transmitted through a photo-coupler, the circuit after the photo-coupler can be isolated from the biasing voltage of the reference signal, and a common power supply can be used for all the stages after the photo-couplers, including servo-motor drivers, of all the channels. This reduces the size and cost of the power supplies as a whole. The non-linear character of the photo-coupler does not cause a positioning error, since the photo-coupler is in the servo-loop having a sufficiently large gain.

  • Patent number: 4236163
    Abstract: A thermal recording stylus has a recording head made of Type IIa diamond. The type IIa diamond has a very good heat conductivity and an excellent abrasion-resistant property. Therefore, the thermal recording stylus with the recording head made of Type IIa diamond has an improved thermal response character, a higher resolution in drawing a line, and a longer life.
