Title: Electrothermal transfer recorder and recording head used therein
Inventor: ONO TADAYOSHI
IPC: B41M5/382
Filed: 1989-04-28
Abstract: PURPOSE:To perform a smooth half-tone picture image recording at high speed by providing an adherence section, through which an ink sheet and a receptive paper adherence-travel, to the point where the ink sheet and receptive paper are separated from each other. CONSTITUTION:Also after passing through a recording electrode 17, an ink sheet 11 and a receptive paper 12 are conveyed through a section A while adhering closely together. Because the temperature of an ink layer surface coming in contact with the receptive paper is raised in a short time to a temperature sufficient for the heat- transition of a coloring material at the time of high-speed recording, a large temperature gradient is generated in the interior of the ink layer and a part of the ink layer on the receptive paper side is melted too. Therefore, when the ink sheet and the receptive layer are peeled from each other immediately after transfer, the ink layer on the resistive layer side is softer and weakens in cohesion though the adhesion of the receptive paper and ink layer is weak so that the ink layer is transferred. However, when the section A is provided, the ink layer resolidifies and its cohesion is restored during the adherence-travel, and the whole or a part of the ink layer is not transferred so that it is possible to obtain smooth gradating properties.

Title: Light propagation member for generating impulse wave and generating method of impulse wave using the same
Inventor: NAGAYAMA KUNIHITO
IPC: F42B3/113
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To enable obtaining an intense impulse wave, by making a light emitting end surface of transparent medium in which a laser light propagates a rough surface finished by a sand paper which has roughness in a specified range. SOLUTION: When an intense laser light propagating in a transparent medium is made to enter an interface with other medium, an intense impulse wave can be generated by making the state of the interface rough. That is, the rough state of the interface means a surface which is obtained by the treatment using a sand paper whose number is 50-3000. By using a propagation member having such a rough surface, an intense impulse wave can be easily obtained without using an intense laser light. The constitution of an initiating equipment part of a blasting cap becomes simple, and a very intense impulse wave can be generated by using only comparatively safe base charge. Since an impulse wave can be made to directly act upon base charge part without intermediate process of thermal conversion, control of the initiating time can be facilitated.

Abstract: PURPOSE:To provide a driving method small in electric power supplied to a source driver, capable of compensating a DC voltage generated by dielectric anisotropy, etc., of liquid crystal and having good electric charge holding characteristics of pixels. CONSTITUTION:As a gate voltage VGi, a 1st bias voltage Vx1 and a 2nd bias voltage Vx2 are applied alternately right before a gate pulse PG.

The drain voltage VDpp can optionally be set by adjusting Vx1-Vx2 or a source driver output voltage VSpp. Specially, VSpp is set equal to the maximum permissible amplitude Va of a video signal component to save the electric power of a source driver output. Its mean value is adjusted to equalize the center value Vdo of VDpp (provided that a common voltage Vc is set equal to Vdo) to the center value of VSpp, thereby compensating the DC voltage.
