Title: Production of ester
Inventor: HIRATA TAKESHI
IPC: C07C67/08
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To obtain an impurity-free high-quality ester by esterifying an alkoxypolyalkylene glycol with (meth)acrylic acid at a specified reaction temperature or below at a specified or higher solvent recirculation rate in the presence of an acid catalyst in a dehydrating solvent. SOLUTION: An alkoxypolyalkylene glycol represented by the formula: R1O (R2O)nH and (meth)acrylic acid in a molar ratio of 1/(1-30), at most 0.4 milliequivalent/g of an acid catalyst such as p-toluenesulfonic acid, and 0.001-1 wt.% polymerization inhibitor such as hydroquinone are added to a dehydrating solvent such as cyclohexane, and the resultant mixture is reacted at 130 deg.C or below at a solvent recirculation rate of 0.5 cycle/hour to a degree of esterification of at least 70%. After the reaction, the reaction product is neutralized with an alkali, and then heated in the presence of 1-1,000 ppm of a added anti-gelling agent such as phenothiazine to distill off the water of reaction and low-boiling materials and to thereby obtain an ester. In the formula, R1 is a 1-30C hydrocarbon group; R2O is an oxyalkylene group; and n is 1-300.

IPC: H04N5/74
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To make a display of high quality without any display defect by adhering a transparent film through an adhesive layer onto the opposite surface of a transparent substrate, where a light valve element is sandwiched, from the side where the light valve element is sandwiched. SOLUTION: This optical modulation element is constituted by adhering transparent films 8 and 9 on the opposite surfaces of two transparent substrates 2 and 3, between which the light valve element 1 is sandwiched, from the side where the light valve element 1 is sandwiched across adhesive layers 6 and 7 which are nearly equal in refractive index. Here, triacetyl-cellulose-based resin films having optical isotropy are preferably used as the transparent films 8 and 9. Consequently, even if there are flaws 4 and 5 on the surfaces of the transparent substrates 2 and 3, no display defect is caused and an image of high quality can be obtained.

Title: Thin-film oxygen sensor
Inventor: ISHIGURO TOSHIYUKI
IPC: G01N27/407
Filed: 1984-12-20
Abstract: PURPOSE:To utilize an oxygen pumping phenomenon in operation at an ordinary temp. and to determine the concentration of oxygen in a gas by laminating the 1st electrode film, a solid electrolyte film and the 2nd electrode film on an electrical insulating substrate. CONSTITUTION:When an electric power source 8 is driven against the 2nd electrode film 14 installed through the 1st electrode film 2 and the solid electrolyte film 3 on the electrical insulating substrate 1, oxygen ions pass through the electrolyte film 3 and flow from the electrod film 2 side to the electrode film 4 side toward the reverse direction against that of the electric current, and so-called pumping phenomenon occurs. Accordingly, when the volume of a chamber consisting of an opening part 5 and a resistor 6 for diffusing oxygen and the impessed current are kept constant, the discharging time of oxygen present in the chamber to the outside corresponds to the concentration of oxygen in an atmosphere to be determined. The oxygen present in the resistor 6 is discharged by increasing gradually the voltage impressed to the electrolyte film 3, and at this point of time the current is saturated, the phenomenon of limiting current is obtained and this limiting current corresponds to the concentration of oxygen in the atmosphere to be determined.

Title: Electric cleaner
Inventor: SOEJIMA MASAKUNI
IPC: A47L9/00
Filed: 1988-10-26
Abstract: PURPOSE:To easily absorb impulse and to prevent damage by constituting the inner periphery of a dust collecting room more widely than the outer periphery of a dust collecting room cover and pinching a bumper attached to a main body lower member. CONSTITUTION:A dust collecting room 11 in an upward opening shape to be positioned in the front part of a cleaner main body 12 is formed in a main body lower part 13 and the upper opening of the dust collecting room 11 is opened/closed by a dust collecting room cover 16, whose back part is pivotally supported to a main body upper member 15. A bumper 14 is composed of an elastic material and a joint part between the main body upper and lower members 15 and 13 and a joint part between the dust collecting room 11 and dust collecting room cover 16 are sealed harmetically. Relation between an inner peripheral dimension E of the dust collecting room and an outer peripheral dimension F of the dust collecting room cover 16 is set to be E<=F. Thus, during cleaning work, when a dust bag in the dust collecting room 11 is filled up and pressure in the room is decreased or when the impulse is received in the dust collecting room cover 16 and main body lower member 13 by the fall of a cleaner, etc., the dust collecting room cover 16 is moved in an arrow D direction. At such a time, since the bumper 14 has elasticity and the wall of the main body lower member 13 is not in a moving direction, the impulse can be efficiently absorbed by the bumper 14. Accordingly, the dust collecting room cover 16 is damaged.

Title: Underground water drainage device
Inventor: WASHITANI HIDEMI
IPC: F04B47/06
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To aim at size-reduction and capacity increase in such device as driving a pump by means of power of a prime mover via a transmission so as to exhaust underground water by achieving speed reduction of a transmission by means of the first step bevel gear train and also changing its direction from its horizontal line to vertical line so as to make speed reduction by means of the second step planetary gear train. SOLUTION: When the rotation of a prime mover is transmitted to an input shaft 1 via a coupling 5, this power is reduced in its rotational speed by means of the first step bevel gear train composed of a bevel pinion 3 and a bevel gear 6 and the direction of its shaft is changed to vertical line from its horizontal line so as to be transmitted to an intermediate shaft 4. The rotation of the intermediate shaft 4 is transmitted to a sun gear 7 making the second step of a planetary gear train and the rotation of the sun gear 7 is transmitted to an output shaft 2 via a planetary gear 9. The rotation of this output shaft 2 drives a pump shaft so as to suck up the underground water by means of a pump.  Since this transmission is formed in a two steps speed reduction structure of such relationship as bevel gear-planetary gear, a distance from the shaft end of the input shaft to the center of the output shaft can be made small so as to provide compactness of a pump machine site.
