Abstract: Provided is a water-repellent member in which a silica layer having a specific thickness and mainly composed of silica nanoparticles is provided on the outer surfaces of various substrates, and then a water- and oil-repellent layer having a specific thickness and containing a cured product of a fluorine-containing organosilicon compound as a main component is provided on the outer surface of the silica layer. The water-repellent member is obtained by a method comprising: a step for wet coating a dispersion containing silica nanoparticles and a solvent onto the outer surface of a substrate; a step for drying and removing the solvent from the dispersion; a step for wet coating a solution containing a fluorine-containing organosilicon compound and a solvent onto the outer surface of a silica layer formed by drying and removing the solvent; and a step for drying and removing the solvent from the solution to cure the fluorine-containing organosilicon compound.

Abstract: A torque transmission shaft between end joints and a cylindrical member. Circlips are fitted in annular grooves formed in the end joints. The circlips abut and lock the outer collars. The outer collars each include a smaller diameter portion, and an end surface of the smaller diameter portion includes a plurality of hollow portions. The hollow portions allow a clearance between a serrated portion and the smaller diameter portion to communicate with the exterior of the outer collar. Air bubbles contained in an adhesive are allowed to escape out of the clearance through the hollow portions, and thus the clearance, is filled with the adhesive densely.

Abstract: A connecting shaft including a first shaft made of metal, a second shaft made of resin, and a collar made of metal including a first fitting portion fitting on an outer peripheral surface of the first shaft and a second fitting portion fitting on an outer peripheral surface of the second shaft. A gap between the outer peripheral surface of the second shaft and an inner peripheral surface of the second fitting portion is filled with an adhesive agent, and the adhesive agent is applied to an outer peripheral surface of the collar to cover an end face of the second fitting portion in an axial direction.

Abstract: An FRP drive shaft includes an end joint joined to at least one end of an FRP cylinder via an outer collar. The end joint includes a serrated portion on an outer periphery thereof. The outer collar includes a small-diameter collar portion and a large-diameter collar portion. The serrated portion is press-fitted into an inner periphery of the FRP cylinder and fixed to an inner periphery of the small-diameter collar portion. A gap between an inner periphery of the large-diameter collar portion and an outer periphery of the FRP cylinder is filled with an adhesive for fixing the inner periphery of the large-diameter collar portion and the outer periphery of the FRP cylinder to each other. An adhesive-accumulating space which partially increases a filling amount of the adhesive is formed between the inner periphery of the large-diameter collar portion and the outer periphery of the FRP cylinder.

Abstract: A torque transmission shaft is configured having increased coupling strength between end joints and a cylindrical member to achieve high transmission torque. Misalignment and disengagement of outer collars (connection members) is effectively prevented in the step of press fitting the torque transmission shaft to another component, such as a constant velocity joint. Circlips are fitted in annular grooves formed in the end joints. The circlips abut and lock the outer collars. The outer collars each include a smaller diameter portion, and an end surface of the smaller diameter portion includes a plurality of hollow portions. The hollow portions allow a clearance between a serrated portion and the smaller diameter portion to communicate with the exterior of the outer collar. Air bubbles contained in an adhesive are allowed to escape out of the clearance through the hollow portions, and thus the clearance is filled with the adhesive densely.

Abstract: An operation machine displays a received image on a monitor to enable an operator to remotely control a moving unit such as a model car and robotic arms through the image provided through a network by a camera on the unit and displayed on the monitor. Plotting of the received image on the monitor is conducted at predetermined intervals in plotting timing. The plotted image becomes a predicted image subjected to a time delay process. The moving unit carrying the camera is disposed in a remote area, and connected to a personal computer through the Internet to transmit motion pictures to the computer. At this time, a fluctuation correction is made to data of the motion pictures to provide a method of displaying a natural image. The method is employed in a moving unit's remote control system enabling an operator to enjoy a precise remote control of the unit.

Abstract: A problem solving support system for supporting problem solving for electronic apparatus users based on user input on how to use the apparatus including an execution program which enables new functions of an electronic apparatus remotely operated by an execution processing section, and an update control section which obtains index word character strings specifying the new functions and element words related to the index word character strings from outside, matches the index word character strings with the element words, stores the obtained execution program in the execution program group storage files, and stores obtained element words in the dictionary database.

Abstract: A problem solving support apparatus 100 for supporting problem solving for users of an electronic device 10 based on user input on how to use the device. The device includes: a related icon storage section 120 which stores a plurality of icons, which are images having appearance conceptually associated with at least a part of an entry word, in association with the entry word which specifies problem solving functions of the electronic device; a candidate icon display section 110 which displays at least a part of the plurality of icons that are candidates for accepting selections from outside on a screen; and an entry word extract section 130 which refers to the related icon storage section 120 to extract the entry word and display the extracted entry word based on combinations of two or more icons when the two or more icons are selected from the icons on the screen displayed by the candidate icon display section 110.

Abstract: An electronic settling system in which illegal use involving a missing IC card is prevented, characterized by comprising an IC card for storing settlement data for settling a charge with a financial institution and payment data corresponding to charges for services or on merchandise, wherein the settlement data is used in effecting a settlement of a charge with a financial institution; an electronic settling terminal carried by a user of the IC card; and, a charge-settling computer for effecting a settlement of a charge on the basis of the data stored in the IC card.
