The H-IIB launch vehicle is an upgraded version of the current H-IIA launch capacity, which has two liquid rocket engines (LE-7A) in the first-stage, instead of one for the H-IIA. It has four SRB-As attached to the body, while the standard version of H-IIA had two SRB-As. One of the major design issue of H-IIB launch vehicle is increased prume heating due to clustering two LE-7A engines and four SRB-As, especially the interaction of engine prumes at high altitude. This paper describes the prume analysys method of H-IIB launch vehicle which is based on the flight proven method of the current H-IIA launch.

Fundamentals of fuel cells including polymer electrolyte fuel cell (PEFC), phosphoric acid fuel cell (PAFC), alkaline fuel cell (AFC), molten carbonate fuel cell (MCFC) and solid oxide fuel cell (SOFC), are presented. Three types of overpotential, activation overpotential, ohmic overpotential and concentration overpotential, are described. Polarization curves in PEFC and SOFC are also presented for better understanding of dominant factors that determine overall cell performance.

Bio-fuel cell, or microbial fuel cells (MFCs) can convert chemical energy of organic compounds to electric power, with their aerobic degradation to CO2 and water. MFCs are analogous to polymer electrolyte fuel cell (PEFC) in terms of the reaction sequences: fuel oxidation, proton transfer and oxygen reduction, whereas MFCs can be also considered as a waste treatment reactor. In this review, in comparison with PEFC, the items explained are the mechanism of MFCs, application of MFCs to wastewater/organic waste (rice straw and excess sludge) disposal, and application of “exoelectrogens” to mediator-less MFCs. Feasibility of MFCs is discussed for designing reactor structures of MFCs as semi-continuous, mediator-less, and single-chambered form.

An ultrahigh vacuum stainless-vessel including only solid samples is used as a “Solid Fusion” vessel. When extremely high purity D2 gas is injected into this stainless-vessel, D2 gas is penetrated into the solid sample as “D+-jet stream” and “Solid Fusion” is generated instantly with 42He and thermal energy as the reaction products. Consequently, the stainless vessel can act as both a “42He generator” and a “Thermal Reactor”. As a result, and excellent actual “Solid Fusion” reactor is established for the first time in the world.

H-IIB Launch Vehicle Test Flight (H-IIB TF1) was successfully launched on September 11, 2009 from the Tanegashima Space Center, with carrying the H-II Transfer Vehicle (HTV) Demonstration which transports supplies to the International Space Station (ISS). The H-IIB is an upgraded version of current H-IIA to meet the requirement of HTV launch, and one of the major items to be new developed is the 5.2m-daiametr first-stage tank. The enlargement of propellant tank diameter causes higher load with internal pressure, the state-of-art welding manufacturing technologies, friction stir welding, is adopted in order to increase the high reliability of the tank structure. This paper describes the results of development process of H-IIB tank by applying the friction stir welding to the axial and circumferential directions with the self-reacting tool called “bobbin tool” which eliminates the use of conventional backing metals.

Crack-free microfabrication of sapphire with little debris deposition and little swelling around ablated regions by laser-induced plasma-assisted ablation (LIPAA) using a second harmonic of Q-switched Nd:YAG laser is described. LIPAA process has been originally developed by ourselves in which merely a single conventional pulsed laser is used. In this process, the wavelength of laser beam must be transparent to the substrate, so that the laser beam goes through the substrate first and is then absorbed by a metal target placed behind. For laser fluence above ablation threshold for the target and below damage threshold for the substrate, the laser-induced plasma is generated from the metal target and then the species fly towards the rear surface of the substrates with very high speed. Due to the interaction of the laser beam and the plasma, ablation takes place at the rear surface of the substrate. Dependence of ablation depth and width of ablated grooves on scanning speed and target-substrate distance are investigated. Based on the obtained results, LIPAA process is applied for scribing of sapphire substrates. Double scan of laser beam with a shift of the focal point shows a great potential of high-quality scribing of sapphire substrates.
