Title: Preparation of soi laminated semiconductor substrate
Inventor: TOMITA SHINICHI
IPC: H01L27/12
Filed: 1993-06-28
Abstract: PURPOSE:To make it possible to reduce the thickness of an active region layer to a specified value or below with less variations, by forming a thin film of a specified thickness, composed of a material having a lower polishing rate than a semiconductor wafer, at the bottom of grooves formed in the semiconductor wafer to be polished. CONSTITUTION:Grooves 6 of such a depth that damage will not reach a second semiconductor wafer 4, are formed in a desired pattern in a first semiconductor wafer 2 by cutting. The bottom faces 6a of the grooves are etched to expose a dielectric layer 3. A thin film 8A of a specified thickness, composed of a material that will be polished slower than the semiconductor wafers under the same condition, is formed on the bottom faces 6a of the grooves. The surface of the first semiconductor wafer 2 is ground and polished until the surface becomes flush with the surface of the thin film layer 8A at the bottom 6a of the grooves. Thus the thickness of an active region layer 9 is controlled by that of the thin film, and does not depend on polishing accuracy. This obtains a SOI laminated semiconductor substrate whose active region layer is 1mum or below in thickness with less variations.

Title: Driving system of thermal head
Inventor: NAMEKAWA TAKESHI
IPC: B41J2/35
Filed: 1983-08-29
Abstract: PURPOSE:To enable the recording of a high quality image free of scrutching and trailing with an improved heat response of a heat generating body by running to the heat generating body of a thermal head a pulse current sharply rising up to the max. value and damping in the time elapsed. CONSTITUTION:A negative recording pulse current is applied to a terminal 4 to turn ON a transistor 2, a voltage of a recording power source 3 is applied to a heat generating body 1 and a differentiation circuit comprising a capacitor 7 and simultaneously with turning ON thereof, a current flows to the heat generating body 1 in such a manner as to rise sharply and then damp along the time constant curve of the differentiation circuit. Therefore, the temperature waveform of the heat generating body 1 also rises sharply and then falls gradually, with the result that the temperature of the heat generating body 1 comes down low sufficiently at the time when the recording pulse is turned OFF. Thus, phenomenon such as scrutchint and trailing of the recording image becomes hard to occur thereby enabling the recording of a high quality image even in a high-speed thermal recorder with a short recording pulse width.

Title: Treatment for sewer sludge
Inventor: KIRIYAMA KOUICHI
IPC: C02F11/04
Filed: 1981-10-07
Abstract: PURPOSE:To improve the solid-liquid sepn. of digested sludge within the range of a digestion process by digesting the initial settling basin sludge produced in sewage treatment facilities anaerobically then mixing the sludge with excess activated sludge and subjecting the sludge to solid-liquid sepn. CONSTITUTION:The initial settling basin sludge produced in sewage treatment facilites are digested anaerobically until 60-75% the org. materials thereof are decomposed. Thereafter, the sludge is mixed with excess sludge and the mixture is subjected to solid-liquid sepn. A dehydration treatment and a combination of a concn. treatment and the dehydration treatment are suitable as the operations for solid-liquid sepn. A settling method, a floating method, and centrifugal concn. can be utilized for the concn. treatment and mechanical dehydration, etc. for the dehydration treatment. This method may cause a decrease in the volume of gases generated as compared to the prior art by as much as the digestion of the excess activated sludge is omitted, but the flocculating properties that the excess activated sludge possesses are acted effectively in the stage of the solid- liquid sepn. by mixing the excess activated sludge as it is with the digested sludge of the initial settling basin sludge.
