IPC: G02F1/313
Filed: 1989-08-30
Abstract: PURPOSE:To lessen an intersection loss by setting the refractive index of the intersected part where plural optical waveguides formed on a substrate intersect with each other smaller than the refractive index of the optical waveguides. CONSTITUTION:An island-shaped region (intersected part) 10 having the refractive index as high as the refractive index of the optical waveguides and a low-refractive index region 11 around this region are formed in the intersected part where the optical waveguides 2 and 3 formed on the substrate 1 intersect with each other. The expansion in the waveguide width is averted even in the intersected part and the generation of multimode components in the intersected part is obviated or even if such components are generated, the ratio thereof is low, if the periphery of the intersected part is made to the low refractive index. The loss by mode conversion, the loss by mode coupling and the loss after the guided light to the other optical waveguide which are the case for the intersection loss are respectively decreased in this way and, therefore, the intersection loss is drastically decreased.

Title: Plasma apparatus
Inventor: MATSUO SEITARO
IPC: H01L21/302
Filed: 1986-09-24
Abstract: PURPOSE:To increase the plasma generating efficiency for improving the manufacturing efficiency, by providing a plasma generating chamber having a structure serving as a cavity resonator with respect to microwave power introduced thereinto, and providing a microwave source generating microwaves intermittently at a frequency higher than a commercial frequency. CONSTITUTION:A single-phase AC power supply 181 of a commercial frequency is connected to a full-wave rectification circuit 182 having no smoothing circuit, and the DC output thereof is applied to a microwave source 11 to drive the same. A plasma generating chamber 1 has a structure serving as a cavity resonator with respect to microwave power introduced into the chamber 1. Accordingly, resonance is caused by driving the microwave source 11 and introducing the microwaves into the chamber. However, the resonance conditions of the plasma generating chamber 1 are changed when plasma is generated by electron cyclotron resonance, and such less efficient conditions will continue if the microwave source is driven continuously as in the case of conventional apparatuses. According to the present invention, the microwave source 11 is driven intermittently so that the plasma generating chamber 1 is allowed to function as the cavity resonator properly according to its original design. Therefore, plasma can be generated at a high efficiency and, as a result, a high film deposition rate and a high etching rate can be obtained.

Title: Forming device for color image
Inventor: GU ZENGIYOKU
IPC: H04N1/46
Filed: 1988-09-12
Abstract: PURPOSE:To enable sufficient reproduction of a color and gradation at all times by modulating each color component signal on the basis of comparison between a plurality of reference signals and a color image signal and by determining selection of a modulation output and a coefficient of color correction corresponding to the result of reproduction of the color. CONSTITUTION:A frequency (a) of a first reference signal 225 is larger than a frequency (b) of a second reference signal 226. When an image is formed by using a pulse width modulation signal 221, therefore, a small latent image is formed in the case when a development characteristic is fixed, and consequently reproduction of a sharp line is enabled by an edge effect of the latent image. When the image is formed by using a pulse width modulation signal 220 modulated by the reference signal 226, on the other side, the reproduction of a line tends to deteriorate, since the dynamic range of a pulse width is wide and a line width for one picture element becomes broad. Accordingly, pulse width modulation by the reference signal 225 is used for reproduction of lines of a character, a graph and the like, since high resolution is thereby obtained, while the pulse width modulation signal by the reference signal 226 is used for reproduction of images such as photographs for which the reproduction of highlight is demanded.
