摘要:
A method of manufacturing an elliptic deep-drawn product including a first step of providing an intermediate product and a second step of providing an end product. In the first step, a rotary forming die is used to form in a blank a substantially round formed portion of a U-shaped cross-section. In the second step, the formed portion is deformed at its semicircular portion by press working to form an elliptic portion, being formed into a final shape.
摘要:
A rib of an airplane wing is prevented from deforming due to a machining load when machining a rivet hole in parts where the rib and a skin are joined. With regard to a rib that provides a connection between first and second spars of the airplane wing, the rib is formed with mounting flanges secured to a skin via a rivet, a stringer through hole for a stringer to be positioned through, and first and second cutouts facing parts where the first and second spars and the skin are connected. Since reinforcing beads are formed along the mounting flanges and reinforcing flanges are formed so as to extend in the span direction from the edges of the stringer through hole and the first and second cutouts and be connected integrally to the mounting flanges, the stiffness of the rib toward a load in the vertical direction when drilling a rivet hole can be enhanced.

摘要:
By a QTL analysis and so forth using 4-HPPD inhibitor-susceptible rice and 4-HPPD inhibitor-resistant rice, a hypothetical gene (HIS1 gene) of an iron/ascorbate-dependent oxidoreductase gene located on a short arm of chromosome 2 of rice has been identified as a 4-HPPD inhibitor-resistance gene. Further, it has also been revealed that a homologous gene (HSL1 gene) of the HIS1 gene is located on chromosome 6 of rice. Furthermore, it has been found out that utilizations of these genes make it possible to efficiently produce a plant having increased resistance or susceptibility to a 4-HPPD inhibitor and to efficiently determine whether a plant has resistance or susceptibility to a 4-HPPD inhibitor.
摘要:
A portable terminal obtains a first code used to obtain provision information and a second code, different from the first code, from a communication device. The portable terminal transmits the first and second codes to an information processing device, receives the provision information from the information processing device as a response to the transmission, and outputs the received provision information. The information processing device includes a first storage unit storing the first code and a second storage unit storing, by associating, the second code and the provision information. The information processing device receives the first and second codes from the portable terminal, obtains provision information associated with the received second code from the second storage unit when the received first code is stored in the first storage unit, and transmits the obtained provision information to the portable terminal. The first code is deleted in exiting from a specific area.

A substrate holding and rotating device includes: a turntable rotatable; a rotative drive unit which rotates the turntable; a holding member which is provided on the turntable and horizontally holds a substrate in upwardly spaced relation to the turntable; a vertically movable protection disk disposed between the turntable and a substrate holding position; and a magnetic levitation mechanism including a first magnet attached to the protection disk, an annular second magnet which generates a repulsive force with respect to the first magnet, a support member which non-rotatably supports the second magnet, and a relative movement mechanism which moves the support member and the turntable relative to each other.
摘要:
There is provided a projection-type display apparatus which solves the problem that when an amount of electric power applied to light sources is adjusted, the amount of electric power involved in the cooling of LEDs becomes greater than necessary. Coolers (107R, 107G, 107B) cool light sources (103R, 103G, 103B). Light sensor (111) detects the brightness of a surrounding area. Light case temperature detectors (112R, 112G, 112B) detect case temperatures which are the temperatures of cases of light sources (103R, 103G, 103B). Light source forward voltage detectors (113R, 113G, 113B) detect forward voltages of light sources (103R, 103G, 103B). Light source forward current detectors (114R, 114G, 114B) detect forward currents of light sources (103R, 103G, 103B). Adjuster (117) adjusts the amount of cooling power of coolers (107R, 107G, 107B) based on the forward voltage, the forward current, and the case temperatures.
摘要:
The present invention relates to a method for producing inorganic oxide particles, comprising at least the following steps of: coagulating a dispersion obtained by carrying out the hydrolysis reaction and the polycodensation reaction of a metal alkoxide in the presence of a basic catalyst; filtering the dispersion to obtain particles; and drying the particles, wherein the step of coagulating the dispersion is carried out by adding a coagulant comprising at least one compound selected from the group consisting of carbon dioxide, ammonium carbonate, ammonium hydrogen carbonate and ammonium carbamate to the dispersion. The inorganic oxide particles obtained by the method of the present invention have high purity and are excellent in flowability.
摘要:
In a power transmission device, a breather chamber having an opening on its one end side and extending coaxially with the countershaft is formed in a countershaft that transmits power from an output shaft of an automatic transmission to a differential mechanism. An inner end of a vent pipe placed so as to extend through a transmission case and that includes the inner end and an outer end each having an opening is inserted in the opening of the breather chamber. A plug, which closes a gap between an inner peripheral surface of the breather chamber and an outer peripheral surface of the inner end of the vent pipe so as to allow air to flow between the inside of the transmission case and the breather chamber and so as to restrict entrance of hydraulic oil into the breather chamber, is placed in the opening of the breather chamber.
