Filed: 1990-05-18
Abstract: PURPOSE:To carry out high precise recording and to attain miniaturization and reduction in cost by providing a transfer/fixing means transferring an image developed on the other periphery of a photosensitive drum to a recording medium, destroying the shell of a developer, and fixing ink inside the shell to the recording medium. CONSTITUTION:A latent image formation with respect to the photosensitive drum 1 is carried out in such a manner that a sensitizing layer 1b is sensitized with image light emitted from an irradiating means with image forming light 2 through a transparent conductive layer 1a inside the photosensitive drum 1. An electrostatic latent image is developed with the developer 3, then, transferred to the recording medium 100 by the transfer/fixing means 5, and the shell of the developer 3 is destroyed to fix the ink 3b inside it to the recording medium 100. Therefore, it happened that the ink 3b, etc., stick to the surface of the photosensitive drum 1, but the latent image formation is carried out from the inside of the photosensitive drum 1, so that any adverse influences are not given to the latent image formation. Thus, the high precise recording can be carried out, and further, a simple, small sized and low-cost image recorder can be obtained.

Title: Formation of insulatng film
Inventor: SHIBATA KAZUYOSHI
IPC: H01L21/31
Filed: 1990-05-21
Abstract: PURPOSE:To enable an insulating film in the film thickness distribution within the range not exceeding + or -5% by a method wherein the gas pressure in a plasma production chamber and a reaction chamber is kept at the level exceeding 90 miliTorr while the current fed to an excitation solenoid is made higher than the current to form an electron cyclotron resonance magnetic field region on the position to maximize the plasma density in the plasma production chamber 7 so as to form an insulating film. CONSTITUTION:The gas pressure in the mutually communicating plasma production chamber 7 and a reaction chamber 8 in an ECR plasma CVD device is kept at the level exceeding 90 miliTorr while the current fed to an excitation solenoid 4 is made higher than the current to form an electron cyclotron magnetic field region on the position to maximize the plasma density in the plasma production chamber 7 so as to form an insulating film. At this time, the ECR magnetic field region taking a curved disc shape can equalize the on-surface distribution of the electrons running from the plasma production chamber 7 to the reaction chamber 8 so that the contribution of gas ions to the film formation may not be concentrated in the central part only thereby enabling the film thickness to be equalized. Through these procedures, the film thickness distribution can be kept within the range not exceeding + or -5% while sustaining the flow rate ratio of N2 gas to SiH4 gas especially indispensable for the formation of a SiN film.

IPC: C02F1/60
Filed: 1994-05-20
Abstract: PURPOSE:To provide a simple and efficient treating method and to enable discharge or reuse in circulation of the remaining liq. after separation and removal by separating and removing the insoluble matter by making the condition in which a specified silicate is allowed to present in the waste liq. in a specified concn., and a nonionic surfactant is allowed to coexist, and pH is kept at <=10.

In the formula I, M is alkali metal, (x) is 0.5<=x<=3.5. Since this waste liq. treating method forms the insoluble matter in a short time under the presence of extremely small amount of silicate as compared with a well-known method, for example, the method in which excess iron and alumina sulfate or activated clay are allowed to present, the amount of the insoluble matter to be separated from a treated waste liq. is small and disposal is very simple.
