Abstract: The present invention is a cosmetic composition comprising, component (A) and component (B), wherein, (A) is carboxylic acid ester of inulin and/or hydrolyzed inulin whose degree of substitution by acyl group is larger than 1, and (B) is cyclic silicone oil, and the present invention is the oily cosmetic compound further containing oleophilic component. More over, the present invention is the W/O type emulsified cosmetic composition prepared by further adding aqueous component and an emulsifier to above mentioned cosmetic compound. In the present invention, acyl group composing component (A) is desirable to be an acyl group of carbon number 14 to 22. Further, a part or all of acyl group composing component (A) is desirable to be palmiroyl group and/or stearoyl group. Furthermore, the above mentioned cosmetic composition can contain dextrin carboxylic acid ester whose degree of substitution by acyl group is 1.6 to 2.5.

Abstract: An injection plug device for injecting concrete repairing agent into a concrete structure and a connector to be connected to such an injection plug device are provided. The injection plug device has a small diameter, a simple structure, and low manufacturing cost to be appropriate to be used as a disposable device.

Abstract: An injection plug device for injecting an epoxy resin repairing agent into an arcuate injection groove formed in a concrete structure. A rod member made of the same or similar epoxy resin as the repairing agent, is inserted and attached in the groove and has an injection hole at its center through which the repairing agent is injected. A tube member protrudes from the center of the rod member and has an inner end portion communicating with the injection hole of the rod member. A pipe member is inserted into the tube member, and a check valve mechanism is provided between the inner end portions of the pipe member and the tube member. After the resin is injected into the concrete structure and the resin is solidified, the pipe member is easily broken and removed from the rod member, together with the pipe member and the check valve mechanism.

Abstract: A concrete repairing agent injection plug for injecting the concrete repairing agent into an injection groove formed in a concrete wall to be repaired, The injection plug and the injection groove provide sufficient fluid tightness regardless of surface irregularities of the wall adjacent or around the injection groove so as to avoid leakage of the repairing agent during injection work. A elastic member is provided which is partly or fully inserted into the injection groove. First and second pressure plates are provided for interposing therebetween the elastic member. Distance between the first and second pressure plates is changeable by a pressure mechanism. When the distance is reduced, the elastic member is compressed and is laterally expanded to brought into intimate contact with walls of the injection groove to thus close an open end portion of the groove.

Abstract: An injection plug device for injecting a concrete repairing agent into a concrete construction through an arcuate injection groove formed therein. The plug device includes a base member sealingly placed over an open end of the arcuate injection groove, a plurality of guide posts extending from the base member, an equal plurality of rod members extending through the guide posts, and engageable member selectively engageable with side walls of the arcuate injection groove by resilient deformation. The engageable members are provided at an inner end portion of the guide posts, or an external surface of the inner end portions of the guide posts. The engageable members have a width smaller than a width of the arcuate injection groove prior to their deformation and have another width larger than the width of the arcuate injection groove after their deformation to provide engagement with the side wall of the groove.

Abstract: An active matrix cell includes a first conductor group formed on a transparent substrate, two-layered regions consisting of a semiconductor film and a first insulating film, a second insulating film and a second conductor group. The first conductor group forms the source and drain of a thin film transistor, pixel electrode, data line. One of the two-layered regions serves as an active region of the thin film transistor and the other of the two-layered regions serves as the intersection between the data and scanning lines. The second insulating film is buried in the gap between the two-layered regions and the first conductor group, and has substantially a same thickness as the two-layered regions. The second conductor group forms the scanning line and the part of the data line. A method of manufacturing the active matrix cell is also disclosed.
