Abstract: In a method of fastening composite material parts, a first smoothness of a first fastener is measured which is arranged to a first countersink through-hole which is formed in a first fastened work as stacked composite material parts. A second countersink depth is determined based on the first smoothness. A second countersink through hole with a second countersink depth is formed in a second fastened work as the composite material parts. The second fastened work is fastened using the second fastener arranged to the second countersink through-hole.

Abstract: Load information and a first processing time are provided in association with each of a plurality of first time segments that each have a fixed duration time and are included in a first time period, where the load information indicates a load condition of a target computer that executed a target job during the each first time segment, and the first processing time indicates a running time of the target job during the each first time segment. One or more first time segments each having a predetermined analogous relationship with a second time segment in a second time period during which the target job is expected to be executed by the target computer are selected to predict a second processing time indicating a running time of the target job during the second time period based on the first processing times associated with the selected one or more first time segments.

Abstract: Provided is a sealant applicator which enables an operator to uniformly apply a given amount of sealant to a fastener in a short time regardless of the skill of the operator. The sealant applicator according to the present invention includes: an inner space defined by a substantially cylindrical inner surface that receives a fastener in an axial direction from one end; and a concave-convex portion formed in the inner surface and composed of a convex portion to be located adjacent to the fastener and a concave portion to be located apart from the fastener.

Abstract: An object of the present invention is to provide means for preparing a monosaccharide by efficiently hydrolyzing a polysaccharide. In particular, in a method that uses a homogeneous acid catalyst to obtain a monosaccharide from a polysaccharide, a low energy, low cost catalytic separation method is provided, and in addition, a method for obtaining high reaction selectivity is provided. In addition, provided is a homogeneous acid catalyst separation method that separates a homogeneous acid catalyst from a homogeneous acid catalyst-containing solution with high efficiency and realizes a high homogeneous acid catalyst recovery ratio at low energy costs, and that is applicable to a variety of reaction systems.

Abstract: It is an object of the present invention to provide a catalyst for manufacturing a carboxylic ester, which has superior catalytic activity. The present invention relates to a catalyst for preparing a carboxylic ester, used in a) a reaction for preparing a carboxylic ester by reacting oxygen, an aldehyde, and an alcohol, or b) a reaction for manufacturing a carboxylic ester by reacting oxygen and one or more types of alcohol, comprising a carrier and 1) ultrafine gold particles and/or 2) ultrafine metal particles containing gold and a second element other than gold, having an average particle diameter of not more than 6 nm, are supported on the carrier.

Abstract: A computer-readable recording medium having recorded a message display control program for notifying that a message has been generated, without interfering with the operation of the user. A notification acceptance block accepts a notification that an event has occurred in a window and obtains notification information related to the event. A notification history message generation block generates a notification history message in accordance with the notification information stored in a notification information database. A window status confirmation block checks whether the window corresponding to the notification information is active. If the window is active, a pop-up message display block displays a pop-up message corresponding to the notification information on the screen. If the window is inactive, a notification icon display block displays a notification icon corresponding to the notification information of the window on the screen of the active window.

Abstract: The present invention provides a process for more efficiently producing an ?-hydroxycarboxylic acid ester wherein side reactions due to the ?-hydroxycarboxylic acid ester are inhibited or prevented in comparison with prior art production processes. The invention provides a process for producing an ?-hydroxycarboxylic acid ester comprising Steps 1 to 3: Step 1. reacting, in the presence of oxygen, (i) a 1,2-diol with a 1,2-diol or (ii) a 1,2-diol with an alcohol to obtain a reaction product containing an ?-hydroxycarboxylic acid ester; Step 2. separating the ?-hydroxycarboxylic acid ester from the reaction product obtained in Step 1 by distillation under reduced pressure; and Step 3. feeding Step 1 with a mixture obtained by partially or entirely removing water from the reaction product, wherein the mixture contains an unreacted 1,2-diol and/or alcohol.

Abstract: To provide an epoxide-production-use catalyst that is suitably used for producing an epoxide by partial oxidation of an unsaturated hydrocarbon, a catalyst in accordance with the present invention is obtained by fixing gold fine particles to a carrier containing an oxide containing at least one of titanium and zirconium, and has an acid quantity of not more than 0.1 mmol/g determined by the NH3-TPD method. Such a catalyst for epoxide producing use can be produced by, for instance, fixing gold fine particles to a carrier having an acid quantity of not more than 0.15 mmol/g. The catalyst for epoxide producing use arranged as above is preferably used as a catalyst in partial oxidation of an unsaturated hydrocarbon to produce a corresponding epoxide.
