摘要:
The present invention relates to a process for preparing hydrogen gas from the reduction of water, and also relates to a process for determining the ratio of the masses between hydrogen isotopes in the obtained hydrogen gas. The invention provides a process of preparing hydrogen gas comprising steps of: (i) preparing zinc metal particles having a size approximately in the range of 1 mm-2 mm by dropping a mixture of a selected amount of liquified zinc metal and 10 to 10000 ppm of nickel elements into a water bath; and (ii) reacting a sample of water with zinc metal particles at a selected reaction temperature to perform the reduction reaction of the water. The invention also provides a process of determining the ratio of the masses between hydrogen isotopes, .sup.1 H and .sup.2 H, in a sample of water. This process comprises a step of preparing hydrogen gas from the sample by the novel method described above.

An analysis apparatus for a printed circuit board. The analysis apparatus includes a processor that executes a process of rewriting physical property data of a wiring layer of a printed circuit board to a value. The value is based on physical property data of an electronic part having a heat-generating attribute. The electronic part is mounted on the portion of the wiring layer. The analysis apparatus converts the physical property data of the portion of the wiring layer that has the electronic part to physical property data of an insulating layer of the printed circuit board.

摘要:
A sound-volume prediction apparatus acquires model information on an electronic device and positional information on an air intake section and/or an air-exhaust section of the electronic device. Furthermore, by using the model information and the positional information, the sound-volume prediction apparatus extends a sound ray that indicates a transmission route of sound generated by a sound source inside the electronic device toward the air-intake section and/or the air-exhaust section from the position of the sound source until the sound ray reaches the outside of the electronic device. The sound-volume prediction apparatus predicts sound transmission characteristics inside the electronic device by using geometric information on the flow path of the extended sound ray.

A counter-rotating axial flow fan with reduced noise at the target operating point achieved without modifying a front impeller, a rear impeller, or a middle stationary portion is provided. An annular rib including a projecting surface for generating turbulent flow is formed on an inner wall portion of a casing at a position off from the middle stationary portion to a side of the rear impeller, the projecting surface extending radially inwardly of the inner wall portion and extending continuously in the circumferential direction of the inner wall portion. A fluid striking the projecting surface for generating turbulent flow is partially disturbed to form a turbulent flow before entering an area in which the rear impeller is provided. The turbulent flow suppresses flow separation of a fluid flowing along the surfaces of rear blades of the rear impeller from the surfaces of the rear blades.
