Title: Semiconductor storage device
Inventor: SATO KATSUYUKI
IPC: G11C11/34
Filed: 1985-06-21
Abstract: PURPOSE:To reduce the current consumption of a dynamic RAM by generating a pulse signal by utilizing the time difference of a time-series operation timing signal for memory access, and rectifying it and generating a bias voltage to be applied to a substrate during memory operation. CONSTITUTION:The address buffer, addresss decoder, and data output buffer DOB of a column system are composed of CMOS static circuits so as to perform a continuous read by switching a column address signal while word lines are selected. Further, a substrate bias generating circuit Vbb-G supplies a negative back bias voltage to the substrate to reduce the parasitic capacity between sources and drains of MOSFETs provided thereupon and the substrate, thereby speeding up the operation. The circuit Vbb-G consists of the 1st substrate bias generating circuit which compensate a fine leak current in a chip nonselection state and the 2nd subtrate bias generating circuit which utilizes the time difference of the time-series operation timing signal generated by a timing control circuit TC.

Title: Treatment of fluorine-containing waste water
Inventor: SABURI OSAMU
IPC: C02F1/58
Filed: 1983-07-22
Abstract: PURPOSE:To prevent fine flocs from being formed at the time of flocculation and efficiently remove fluorine from a fluorine-containing waste water, by simultaneously adding a calcium salt and an iron salt to the fluorine-containing waste water, by simultaneously adding a calcium salt and an iron salt to the fluorine- containing waste water to effect sufficient reaction, followed by flocculation. CONSTITUTION:A calcium salt and an iron salt are simultaneously added to the fluorine-containing waste water, whereby the iron salt is converted into iron hydroxide, and fine flocs of calcium fluoride are adsorbed on flocs of iron hydroxide. A portion of complexes is also adsorbed on the flocs of iron hydroxide, and is separated by flocculation. As a result, the concentration of fluorine in the supernatant water in a settling tank approaches a theoretical solubility of calcium fluoride of 8mg/l (calculated as fluorine). The concentration of fluorine in the supernatant water flocculation is brought to a value appoximate to the theoretical value of 8mg/l by the addition of the iron salt as well as the calcium salt, as contrasted to the case of sole addition of the calcium salt wherein the fluorine concentration is 20mg/l.

Abstract: PURPOSE:To accelerate separation by physical means by constituting a titled device of a separating vessel of double cylinders wherein an outer cylinder and an inner cylinder are provided by coaxial combination, screw vanes for accelerating a separating effect and a unit for rotating and driving the screw vanes. CONSTITUTION:A heating medium is circulated in the space 11 of an outer cylinder 1 and a cooling medium in the space 21 of an inner cylinder 2. Waste liquid contg. sludge is introduced into an annular space 3 through an inlet 31. The waste liquid forms ascending flow. Since the waste liquid is heated by the heating medium and is cooled by the cooling medium, the liquid flows upward as it is assisted by screw vanes 8 while creating the ascending flow and descending flow. A potential difference is generated by the effect thereof, by which colloid is broken and fine particle groups are made hydrophobic from hydrophilic. Such liquid overflows from the top end of the cylinder 2 and enters the space 4. While the liquid is moved downward by the effect of screw vanes 6 in the space 4, the liquid is separated to sludge and supernatant. The sludge is discharged through a discharge port 41 and the supernatant through a discharge port 42.

Title: Turned letter checking supporting device
Inventor: GOMI HIDETAKA
IPC: B41B25/26
Filed: 1995-06-01
Abstract: PURPOSE: To prevent the oversight of a turned letter font and replace easily the same to a corresponding letter font. CONSTITUTION: A turned letter font in the data of a raster image forming print display image conversion section 10 is found by the image identification method carried out by an image identification processor 12. The turned letter font thus found is passed through an image data rewriting section 14, and a turned letter checking section 16, and is output in transparent color different from the color of ordinary font, so the turned letter font is not overlooked. On the other hand, the turned letter font is output through the image data rewrite section 14 and a final print display output section 18 to be output colorlessly, so it is unnecessary to erase the turned letters at the time when the turned letters are replaced by a corresponding final letter font.
