Abstract: PURPOSE:To realize a practical surface optical modulator with a low loss and high modulation efficiency by increasing effective optical density in an optical modulation layer and improving modulation efficiency for inputted light. CONSTITUTION:The modulator has the structure such as a quantum thin film, a quantum thin line and a quantum chamber trapping electrons or holes or both in one dimensional direction and the width of the trapping structure is narrower than the De Blois wavelength of the electron or the hole or narrower than the Bohr radius of an excition within the trapping structure while having a quantum structure in which quantum effect occurs remarkably, absorption coefficient, refractive index and polarization characteristic are changed by means of control signals such as external control light and an electric signal and the incident light in the direction almost perpendicular to the laminating direction of the quantum thin film or the arranging direction of the quantum thin line, quantum chamber, etc., are optically modulated. The modulator has the region 4 (optical trapping layer) with effectively lower refraction index than that of the optical modulation layer in the direction around the surface of the laminating layer 3 in which absorption coefficient, refractive index and polarization characteristic are changed.

IPC: G03G15/08
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To prevent base soil and toner scatter in the case the linear velocity of a developer carrier is altered, by setting the toner density of developer when the carrying speed of the developer carrier is the highest to critical toner density, at which a layer of toner covers the surface of one carrier, or below. SOLUTION: The toner density of developer when the carrying speed of a developer carrier is the highest is set to a critical toner density, at which a layer of toner covers the surface of one carrier completely, or below. That is, a toner concentration control value when the linear velocity of a developing sleeve 4 is the highest is set to the critical toner density or below. For instance, when the linear velocity of the developing sleeve 4 is 300 mm/sec, the ratio of the toner density control value to the critical toner concentration is 100%. More specifically, for example, a development gap is set to 0.4 mm, doctor gap to 0.3 mm, a predoctor gap to 1.0 mm, a developing-roller magnetic force to 65 mT, and an amount of developer to approximately 40 g.

A delay circuit DC retards the 2nd digital picture signal DPS2 and outputs the 2nd digital picture signal DPS2' whose line number and picture element address are coincident to the 1st digital picture element image signal DPS1. A signal converting circuit SC applies time devision multiplex at each other picture element to output a multiplex digital picture signal MDPS. Then a coding circuit CC transmits a coded data CDD to a transmission line from an output terminal OUT.
