Abstract: A zirconia sintered body that includes a transparent zirconia portion and an opaque zirconia portion has a biaxial bending strength of 300 MPa or more. In addition, the opaque zirconia portion is configured by an opaque zirconia sintered body that is any one of a dark-colored zirconia sintered body, a medium-light-colored zirconia sintered body, and a light-colored zirconia sintered body.

Abstract: A sintered body includes zirconia, iron, cobalt and titanium, in which a total iron and cobalt content is more than 0.1 mass % and less than 3 mass % and a titanium content is more than 3 mass %.

Abstract: An engine start controller includes an injection amount calculating portion that is configured to calculate, as an assist injection amount, an injection amount of fuel injected from a fuel injection valve of an engine in an engine start-up period until the engine rotation speed exceeds a predetermined starting rotation speed from zero. The injection amount calculating portion is configured such that, in a case in which the rotation speed of the engine is higher than or equal to a threshold value that is a value less than the starting rotation speed, the injection amount calculating portion calculates the assist injection amount to be smaller when the engine is started by using the motor generator than when the engine is started by using the starter.

Abstract: A regeneration controller that is employed in a hybrid system is configured to control a regenerative braking amount of a motor generator. A hydraulic brake is configured such that a hydraulic braking amount applied to a vehicle is decreased after the depression amount of the brake pedal is decreased by a predetermined first hysteresis amount from the start of a decrease in the depression amount. The regeneration controller is configured to control the motor generator such that, when the depression amount of the brake pedal is decreased, the regenerative braking amount starts decreasing after the depression amount of the brake pedal is decreased by a second hysteresis amount from the start of a decrease in the depression amount. The second hysteresis amount is set to be greater than the first hysteresis amount.

Abstract: A dehumidifying material comprising: 90.0 parts by weight to 99.9 parts by weight of silicon dioxide which is silica gel; and 0.1 part by weight to 10.0 parts by weight of an iron oxide or a mixture of the iron oxide and another metal oxide and a dehumidifying element incorporating an inorganic fiber sheet supporting the dehumidifying material, the dehumidifying material being obtained by allowing alkali silicate or alkokysilane to adhere to an inorganic fiber sheet to gel the inorganic fiber sheet, by immersing the inorganic fiber sheet in solution containing iron salt or iron and other metal salt and by drying the inorganic fiber sheet.

Abstract: A carton for shipping and displaying articles for sale. The shipping carton is converted to a display by removing and discarding an upper portion and folding a part of the remaining lower portion under the floor of the carton to form a base for tilting the carton. The carton is folded from a single blank and all exterior surfaces of the carton, and the front and side exterior surfaces of the display, can be finished on one side of the blank.

Abstract: A carbon fluoride comprising carbon atoms and fluorine atoms and having a structure in which layers containing fluorinated condensed cyclohexane rings are stacked to form a packing structure, the atomic ratio of fluorine to carbon atoms being 0.5 to 1.8, the carbon fluoride exhibiting a powder X-ray diffraction pattern in which there are peaks respectively at about 13.degree. (2.theta.) and at about 40.degree. (2.theta.) and no peak on the low side of diffraction angle relative to 13.degree. (2.theta.) and exhibiting a spectrum of electron spectroscopy for chemical analysis in which there are peaks respectively due to a monofluorocarbon group and due to a difluorocarbon group, the intensity ratio of the peak due to the difluorocarbon group to the peak due to the monofluorocarbon group being 0.15 to 1.5. The carbon fluoride has a unique property that it is capable of forming a film by vacuum deposition. The carbon fluoride may be produced by the direct fluorination of a pitch or meso-carbon microbeads.

Abstract: A flat flame burner comprises an air swirling chamber, an air supply tube provided for the air chamber for introducing combustion air thereinto in the peripheral direction of the air chamber so as to produce a swirling air stream in the chamber, a fuel gas supply tube disposed in the air chamber and having inlets centrally of the space for the swirling air stream and a flame opening positioned at one side in the direction of axis of the swirling air stream coaxially with the swirling air stream, the flame opening being defined by a wall having a thin portion around said opening and a flat outer face.
