Title: Forming method for ablation image
Inventor: NEUMANN STEPHEN M
IPC: B41J29/00
Filed: 2001-08-13
Abstract: PROBLEM TO BE SOLVED: To arrange an over-coating layer wherein a relief image does not project, and also, there is no air trap, on an ablation recording element. SOLUTION: The ablation recording element is heated by a laser means along an image. In this case, the ablation recording element contains a supporting body which has an image layer containing a coloring agent dispersed in a polymer binder on the top. Thus, the image layer is ablated along the image. In this case, the image layer is combined with a near infrared ray absorbing material so that the absorption may be performed by a specified wavelength of the laser used for the irradiation of the image layer. The coloring agent is absorbed in a region of 300 to 700 nm (a). Then, a coating containing a polymer particle dispersed in a binder is laminated on the surface of the ablation image under heat and a pressure so that a continuous over-coating layer may be formed by melting the particle.  This forming method for a single color ablation image wherein wear-resistance is increased, includes such a lamination (b).

Inventor: ARIGA MITSUO
IPC: H03F1/32
Filed: 2001-08-30
Abstract: PROBLEM TO BE SOLVED: To improve efficiency of an amplifier circuit and eliminate the distortion of an output signal waveform. SOLUTION: Diodes 5 each serving as a half-wave rectification section are provided on a signal conducting lines between a distributor 2 and control terminals of respective active elements 3a, 3b in a push-pull amplifier circuit. Since signals which are half-wave rectified by the diodes 5 are applied to the control terminals of the elements 3, e.g. if bias is applied to the control terminals of the elements 3 from a bias input section 6, the elements 3 output signals having a half wave waveform to a combination section 4, and an amplifier circuit functions in the same way as a class B push-pull amplifier circuit. This amplifier circuit has a higher efficiency compared to an class A circuit similarly to a class B push-pull amplifier circuit.  Further, bias for preventing the distortion of an output signal waveform due to an operation of the element 3 is applied to the control terminals of the element 3, thus the distortion of an output signal waveform which is a drawback of a B-class push-pull amplifier circuit can be prevented.
