Abstract: A wearable terminal device that is configured to be used by being worn by a user includes at least one processor. The at least one processor detects a visible area for the user in a space. The at least one processor causes a display to display, out of virtual images located in the space, a first virtual image that is located inside the visible area. When a second virtual image located outside the visible area is present, the at least one processor causes the display to perform display indicating in a prescribed manner existence of the second virtual image.

Abstract: A wearable terminal device is configured to be used by being worn by a user. The wearable terminal device includes at least one processor. The at least one processor detects a visible area for the user inside a space and causes a display to display an instructional image located inside the visible area. When there is an instructional image located outside the visible area, the at least one processor issues a first notification making the user aware of the existence of the instructional image. As a result of this first notification being issued, the user of the wearable terminal device is able to notice the existence of the instructional image generated by an instruction given by a remote instructor.

Abstract: A wearable terminal device is configured to be used by being worn by a user. The wearable terminal device includes at least one processor. The at least one processor causes a display to display a virtual image that is located inside a space and has a first surface and a second surface on an opposite side from the first surface. The at least one processor determines whether the first surface or the second surface is easier for the user to see. When the second surface is determined to be easier to see, the at least one processor causes an image of the first surface of the virtual image to be displayed on the second surface of the virtual image.

Abstract: An image reading apparatus includes a first reading section configured to read a first plane of the document, a second reading section configured to read a second plane which is a back side of the first plane, a first controller stops the reading of the first reading section after causing the first reading section to read a last line before the reading of the first reading section is stopped and transmits a reading stop instruction to a second controller earlier than a timing when the first reading section reads the last line by a time difference corresponding to a delay generated in communication between the first and second controllers. The second controller stops reading of the second reading section after causing the second reading section to read one line in response to the reading stop instruction.

Abstract: An inorganic/organic composite foam that has a foam structure obtained from a combination of a phosphoric acid compound and/or a sulfuric acid compound with a blowing agent therefor, has reduced brittleness due to a cured material of an urethane prepolymer having NCO groups, and contains a powdery boric acid compound, and a process for producing the same. The foam is not only reduced in brittleness but also improved in foam strength after combustion due to the incorporation of the powdery boric acid compound while retaining inherent foam properties and inherent low quantities of heat of combustion and smoking in combustion. It is used in exterior wall panels, heat insulating materials, sound insulating materials, fireproof covering materials, lightweight aggregates, filling materials for cavities, and the like, which are required to have fire-proofing performance.

Abstract: A inorganic-organic composite foam having a structure comprising phosphoric acids and a blowing agent for phosphoric acids, wherein the brittleness is improved by urethane prepolymer having NCO groups. The foam is produced by foaming and curing by mixing each component of phosphoric acids, a blowing agent for phosphoric acids, urethane prepolymer having NCO groups, water, and, if necessary, an inorganic filler. A foam of phosphoric acids is inherently brittle, but the brittleness is improved, and flexibility and rebound resilience can be provided. The foam of the present invention is effectively used for the applications, for example, heat insulating materials of external panel or internal panel which require the fire preventive property of train, automobile, housing, building etc.
