Title: Wall-coating material composition for interior
Inventor: TSUJIMOTO MITSUHARU
IPC: C09D7/12
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To impart an excellent adsorptive decomposability of aldehydes to a wall-coating material for interior by compounding an aggregate, an adhesive and a chemical adsorbing agent for aldehydes in the composition. SOLUTION: As an aggregate, one or more selected among silica sand, wood flours, natural pumice, artificial aggregates and crushed stones can be used. As an adhesive, for example, a carboxymethyl cellulose sodium salt, methyl cellulose, natural gum and the like can be used. As a chemical adsorbing agent for aldehydes, at least one selected from among hydrazies, azoles and azines is preferable. Incorporation of the chemical adsorbing agent for aldehydes in an amount of at least 5 g relative to the amount of a wall-coating material composition for interior to be coated on 3.3 m2 of a wall surface brings about a substantially sufficient adsorptive decomposition effect of aldehydes.  The aggregate, the adhesive and the chemical adsorbing agent for aldehydes, and if required, a tying material, a humidity-controllability-improving agent, a colorant, a soft texture-imparting material or the like are admixed to give a wall-coating composition for interior.

Title: Solvent cleaning method in chemical reprocessing of nuclear fuel
Inventor: SUGAI HIROSHI
IPC: G21C19/46
Filed: 1991-12-09
Abstract: PURPOSE:To prevent the formation of clad at the solvent cleaning time in chemical reprocessing of spent nuclear fuel by cleaning while maintaining pH at the specified value or ligher at the time of cleaning using an alkaline cleaning agent such as a sodium carbonate aqueous solution in reprocessing. CONSTITUTION:In a cleaning method enabling the prevention of clad, zirconium and di-n-butyl phosphoric acid complex, zirconium and mono-butyl phosphoric acid complex, and zirconium and phosphoric acid complex, which are the cause of clad formation, are to be in a region of pH 8 or more so as to exist stably in an aqueous solution because of being changed into extremely high hydrophile precipitation under the influence of a hydroxyl group in a region of high hydroxyl concentration. The percentage of being captured in an interface between the aqueous solution and a solvent necessary for the formation of clad is thereby considered to be lowered in large degree. Accordingly, the important point for clad prevention is to raise the hydroxyl group concentration at the cleaning time, that is, to make pH high, and organic alkali and the like as well as inorganic alkali such as sodium hydroxide can be used as the pH conditioner.

IPC: H05B3/00
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a fixing device eliminating the influence of initial tempera ture of a heating roller, previous remaining heat, and the like and reducing ripple in receiving or starting copying so as to be short in waiting time until the start of fixing and low in cost by changing the rate of light-on time and light-out time of a heating means according to the detected temperature of the heating roller at the time of starting action. SOLUTION: Upon receiving a facsimile input signal or a copying start signal, a heater 93 of a fixing device 9 is continuously lighted, and the device is made stand by until the detected temperature of a thermistor 94 reaches the write start temperature. When the input signal or start signal is received, the detected temperature of the thermistor 94 is detected. When the detected temperature is high, the rate of heater lighting time to the elapsed time, that is, a duty ratio, is made small, and when the detected temperature is low, the duty ratio is made large. The temperature rise is thereby expedited when the temperature at the time of starting action is low, and the rate of temperature rise is suppressed as the temperature at the time of starting action is higher, so that the temperature ripple of the heating roller 91 can be suppressed.

Abstract: PURPOSE:To prevent reflected light from a manuscript area readable from one picture element from entering other picture elements which exclude the reflected light and enhance the resolution (MTF) of an image sensor in a picture reader which integrates a light emitting element with a contact image sensor. CONSTITUTION:A photodetector 100 formed on a first substrate 10 and a light emitting element formed on a second substrate are laid out so that they may be opposed to each other with a transparent layer 300 clamped and light from the light emitting element 200 is applied to the surface of a source manuscript 400 laid out on the opposite side of the light emitting element 100 of the second substrate 20 and the reflected light is arranged to enter the light receiving element 100, thereby constituting an image reader. Since the transparent layer 300 is formed with a medium whose refractive index is smaller than that of the second substrate 20, the reflected light from the source manuscript 400, which is going to enter the transparent layer 300 at an incident angle which exceeds a critical angle which can be determined with a ratio of a refractive index between the second substrate 20 and the transparent layer 300, is totally reflected on the top of the transparent layer 300 and prevented from entering the light emitting element 100.
