摘要:
An X-ray generation unit and an X-ray detection unit are held by an arm. Image data is generated based on X-ray projection data which is generated by the X-ray detection unit. A first support member supports the arm and rotates the arm in a first rotation direction. A second support member supports the first support member. The second support member rotates the first support member around a rotation center in a second rotation direction perpendicular to the first rotation direction. A movement unit can move the second support member in an up and down direction.

A bonding structure includes a first member, a second member and a bonding member. The first member has a plate shape and is made of a carbon-base material. The first member serves as a heat diffusion member that transfers heat at least in a thickness direction, which is perpendicular to a plane of the plate shape. The second member is bonded to the first member through the bonding member. The first member has a metal thin film at least on an opposed surface that is opposed to the second member. The bonding member is disposed between the opposed surface of the first member and the second member. The bonding member is provided by a sintered body of metal particle. For example, the bonding structure is employed in a cooling unit including a heat source.

A fuel supply apparatus for an internal combustion engine includes a fuel pump disposed in a fuel tank. The fuel tank is supported by a tubular bracket secured to a mounting plate installed in an opening of a fuel tank and extending into the fuel tank. The bracket surrounds the fuel pump and restrains the fuel pump along its outer periphery. The bracket may include inwardly projecting portions for restraining the fuel pump.

A thin-film electroluminescent device includes dielectric layers having improved dielectric characteristics. The device is fabricated by forming a first transparent electrode layer of ITO, a first dielectric layer, a luminescent layer, a second dielectric layer, and a second transparent electrode layer of ITO in this order on an insulating substrate. Each of the two dielectric layers is a film constituted by TaSnON. That is, the film includes tantalum, tin, oxygen, and nitrogen.

A control system is provided for servo hydraulic pressure in an automatic transmission. Upon downshifting, one of first and second frictional engagement devices is released while the other is engaged. A directional control valve is provided to feed or drain servo hydraulic pressure to selectively engage or release the first and second devices. The hydraulic pressure is regulated by a pressure regulator under the control of an electronic control unit. Detectors are also provided to determine input rotation and torque, respectively. The regulator is interposed between the directional control valve and the engaged device. The regulator is controlled to maintain the servo hydraulic pressure at a predetermined value under the control of the electronic control unit until predetermined input rotation is detected and then to gradually raise the servo hydraulic pressure under the control of the electronic control on the basis of the value of input torque.

A copper alloy suitable for use as the material of a heat exchanger contains 1 to 4.5 wt % of Zn, 1.0 to 2.5 wt %, preferably 1.5 to 2.0 wt % of Sn, 0.005 to 0.05 wt %, preferably 0.01 to 0.04% of P, and the balance substantially Cu and inevitable impurities, and has grain size not greater than 0.015 mm, preferably below 0.01 mm. The alloy exhibits high resistance levels to corrosion such as stress corrosion cracking, dezincification corrosion and so forth, as well as superior workability, strength and solder wettability, and, hence, can suitably be used as the materials of the constituents of a heat exchanger such as tanks, tube plates and tubes.

There is provided a polymer or low-molecular-weight compound multilayer type organic EL device configured such that a light-emitting layer formed on a hole transport layer includes a mixture of a polymer material and a low-molecular weight material. With such a configuration, the low-molecular-weight material added to the polymer material serves as a binder filling the gap of the steric hindrance to form entanglement of the polymer material and the low-molecular-weight material. This results in that the interface between the hole transport layer and the light-emitting layer is an interface high in adhesion and also high in carrier injectability. Further, optimization of the formation conditions and materials can achieve still higher reliability and longer lifetime.

An X-ray diagnostic apparatus includes a floor rotating arm which is installed at one end on a floor surface so as to be rotatable around a first rotation axis, a C-arm which is mounted on the other end of the floor rotating arm so as to be rotatable around a second rotation axis, an X-ray tube which is mounted on one end of the C-arm, an X-ray detector which is mounted on the other end of the C-arm, and a bed which has a table top provided to be movable along a longitudinal axis. The bed is placed such that the longitudinal axis is spaced apart from the first rotation axis by a predetermined distance.
