Abstract: A jet engine includes an inlet (11) which takes in air and a combustor (12) which combusts fuel with the air. The combustor (12) has an injector (20), a plurality of flame stabilizers (21, 22) and a vanishment section (31). The injector (20) injects the fuel. The plurality of flame stabilizers (21, 22) can maintain the flame (F) used for combustion in the combustor (12). The vanishment section (31) is provided to cover the dent of the first flame stabilizer (21) which is situated on the side near to the inlet in the plurality of flame stabilizers (21, 22), and vanishes with the passage of time in the flight.

Abstract: An armored vehicle includes: a basic armored vehicle having a predetermined basic external armor; a modularized armor structure exchangeably attached to the basic external armor; and an unmanned aerial vehicle loaded on the modularized armor structure. The modularized armor structure includes: an unmanned aerial vehicle loading section configured to load the unmanned aerial vehicle; an armoring material structure formed of armoring material; and an attaching section used to exchangeably attach the modularized armor structure to the basic armored vehicle.

Abstract: An aerial vehicle includes an outer surface, an arithmetic unit and a control unit. The arithmetic unit calculates a control command using a control parameter. The control unit controls an attitude of the aerial vehicle or a thrust of the aerial vehicle based on the control command. At least a part of the outer surface of the aerial vehicle is composed of ablation material. The arithmetic unit changes the control parameter in response to an amount of shape change of the aerial vehicle caused by disappearance of the ablation material.

Abstract: A computer-readable recording medium having recorded therein a telephone-call connection program for controlling telephone calling with the schedule of the other party of a call and a call importance level therefor being taken into account. A connection-request receiving block extracts a transmission-source telephone number and a transmission-destination telephone number and identifies the other party of the call from the transmission-destination telephone number. Then, a call-importance-level determination block determines the call importance level of the call for the other party of the call. A schedule determination block determines whether the current time falls in a response-rejection time zone of the other party of the call. A connection determination block determines according to the response-rejection time zone and the call importance level whether telephone calling is necessary.

Abstract: A rolling guide apparatus includes a race shaft on which a rolling element rolling surface is formed in a longitudinal direction thereof, and a sliding table having an endless circulation passage. The endless circulation passage includes a load rolling surface corresponding to the rolling element rolling surface. Plural rolling elements are housed in the endless circulation passage. The sliding table has a sliding table main unit and side covers attached to respective ends of the sliding table main unit. The sliding table main unit has a load rolling surface section having the load rolling surface, and a main body section. The load rolling surface section is made from engineering ceramic. The main body section is made from machinable ceramic.
