Abstract: A composition comprising an incineration ash or an aluminosilicate as a raw material is added with an aqueous alkaline solution from an alkali storage tank (3) and heated. The resultant pre-mixture is then mixed and kneaded by a kneader (4) to prepare a kneaded mixture (19) in the form of a slurry or mud. The kneaded mixture (19) is moved continuously and irradiated directly with an electromagnetic wave of 300 MHz to 30 GHz in an electromagnetic wave irradiation unit (21), to thereby convert it to zeolite. The zeolite thus formed is cleaned by means of a cleaning machine (7) and dried with a rotary steam dryer (9). This method can be employed for producing an artificial zeolite with a reduced amount of alkali used and discharged, at a lower energy expenditure, and a reduced time for production.

Abstract: In a horizontal transfer section of a solid state imager, a horizontal transfer efficiency can be improved while other element sections are prevented from being substantially affected. In a solid state imager having a horizontal transfer section comprised of a well-region of a second conductivity type formed on the surface of a semiconductor substrate of a first conductivity type and a signal charge transfer region formed on the surface of the well-region of the second conductivity type, the well-region is formed completely in a depletion state by the implantation of impurities into this well-region. The horizontal transfer efficiency is thus improved.

Abstract: A charge-coupled device (CCD) imager is comprised of a CCD image sensor, a horizontal register for delivering an image signal from the CCD image sensor, the horizontal register being formed of an effective bit portion corresponding to the CCD image sensor and first and second dummy bit portions of a predetermined length which are located at both sides of the effective bit portion, and first and second output portions provided in succession to the first and second dummy bit portions to provide a positive image signal and a mirror image signal, wherein the effective bit portion is provided with four bus lines through which a transfer clock is supplied to the horizontal register and the first and second dummy bit portions are provided with two bus lines through which a transfer clock is supplied to the horizontal register. Thus, the CCD imager can be simplified in arrangement and a undesirable charge can be prevented from being mixed into a signal charge.

Abstract: There is disclosed a process for coating particles, such as ceramic, metallic and organic cores, with fine powder, such as ceramic, metal, organic or carbon powder. The process comprises providing a mixture comprising the particles and a binder which is capable of slowly melting to viscous state. Then the mixture is tumbled while slowly heating it to enable the binder to reach the viscous state while allowing the particles to be substantially covered with the binder. The next step includes cooling the mixture to about room temperature and thereafter breaking up the particles that may have agglomerated during the tumbling and heating to give individual particles covered with the binder. As a final step, the fine powder is added to the individual binder covered particles and the mixture is tumbled and heated again to the viscous state under conditions effective to provide a coating of the fine powder on the particles.
