Title: Analysis of solution
Inventor: KAMIMURA KENICHI
IPC: G01N27/26
Filed: 1994-01-12
Abstract: PURPOSE:To realize an accurate, quick and convenient titration by using an organic solvent. CONSTITUTION:A substance containing a basic solute is dispersed into an organic solvent. Organic solvents, i.e., methanol, ethanol and acetone, have dielectric constants of 32.6, 24.3 and 20.7, respectively, at 25 deg.C which are lower than the dielectric constant of water, i.e., 78.5. Consequently, when similar acid substances are dissociated, they are dissociated easily in a water having higher activity. Dissociation is retarded in a solvent having a low dielectric constant and even such substances as having close dissociation states in the water can be separated in a solvent having a low dielectric constant. The dissociation constant in an aqueous solution is 3.2 for hydrofluoric acid and 4.8 for acetic acid and the difference is 1.6 but in an ethanol solvent, the dissociation constant is 7.2 for hydrofluoric acid and 10.2 for acetic acid and the difference is 3.0. Consequently, the inventive method can separate even such a substance that has not been able to be separated conventionally in an aqueous solution.

Title: Semiconductor memory device
Inventor: IWAHASHI HIROSHI
IPC: G11C29/00
Filed: 1985-01-26
Abstract: PURPOSE:To measure the reliability of even a memory cell where the floating gate is electrified positively and the threshold voltage has a negative polarity, by supplying a prescribed voltage supplied from the external to a sense amplifier through a transistor TR as a reference voltage. CONSTITUTION:The drain of a dummy cell TR13 having the floating gate is connected to the source of a TR41 together with a load circuit 14. The gate of the TR41 is controlled by a bias generating circuit 50 connected to a voltage from an external terminal 51, and the external voltage from a terminal 42 is supplied directly to the TR13. Then, the reliability is tested on a basis of variance or nonvariance of the threshold of a memory cell TR11 having the floating gate according as the external voltage from the terminal 42 by which the output of a sense amplifier 25 is inverted at a normal temperature and that after leaving the memory cell at a high temperature for a long time are equal to each other or not. By this constitution, the reliability of even the memory cell where the floating gate is electrified positively and the threshold voltage has the negative polarity can be measured.

Title: Image output device
Inventor: EJIMA YOSHINORI
IPC: H04N1/23
Filed: 1987-01-22
Abstract: PURPOSE:To obtain the same reproduce image density for the same original picture element density by storing the sensitivity state of a photosensitive body previously and correcting the quantity of laser light or an radiation time according to the stored state. CONSTITUTION:A correction ROM 21 is stored with correction coefficients predetermined corresponding to the relation of an irregularity (sensitivity: L>M>N) of the spectral sensitivity of a photosensitive body 8. Digital image data VD inputted in synchronism with an image clock CK has an information quantity (gradation data) in a depth direction as to one picture element and is processed by picture elements through an adder 23 with correction data CD outputted corresponding to input picture elements in synchronism with the image clock CK from the correction ROM 21. Consequently, the outputted corrected image data CVD is converted by a D/A converter 25 into an analog quantity. The analog image data AV is compared with a triangular wave TS and the irradiation time of a laser per picture element is controlled. Consequently, excellent image output having no density irregularity is enabled.

IPC: G03G9/08
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To produce a polymerized toner having a low fixing temp. and uniform meltability, excellent in preservability (blocking resistance) and fluidity, hardly causing fog and hardly lowering printing density. SOLUTION: A polymerizable monomer compsn. contg. at least a colorant, a polymerizable monomer and a releasing agent is suspended in an aq. dispersive medium contg. a dispersion stabilizer to form droplets. The compsn. is suspension-polymerized in the presence of an oil-soluble polymn. initiator until the rate of polymn. conversion attains to the range of 30-95%. While the rate of polymn. conversion is within the range, a reducer for the redox initiator is added to the dispersive medium, the suspension polymn. is further succeeded to form colored polymer particles and the objective polymerized toner is produced. When a polymerizable monomer for shells is suspension-polymerized in the presence of the colored polymer particles to form polymer layers as shells on the surfaces of the particles, the objective toner having a core/shell structure is produced.

Abstract: PURPOSE:To reduce testing costs, by transmitting monochromatic light rays to the bottom of a sample container, in which aggregate of red blood corpuscles to be compared is contained, along the longitudinal direction of the container, and automatically detecting the presence or absence of a specified immune material in the sample. CONSTITUTION:Light rays emitted from a tungsten halogen lamp 24 are converged through a lens 26 and a prism 28. The light is projected on at least about 65% of the bottom of a sample container 112. A light detector 32 is located under the container 112 and measures the amount of light, which is not shielded by the aggregate of red blood corpuscles in the container 112 and passes through the container 112. The signal, which is proportional to the measured amount of the light that is not shielded, is sent to a computer 34 from the detector 32. The computer 34 classifies the corpuscles in the container 112 as the function of the aggregate of the red blood corpuscles. The result is displayed by, e.g., printout. This apparatus has a mechanism 36, which moves a plate. The test plate is automatically moved, and the sample containers are sequentially recorded by the light rays. Therefore the blood coagulation test can be automatically conducted.
