Abstract: A vehicle body lower part structure includes: a side frame that connects a side sill to a battery pack that is arranged below a floor portion; and a battery frame that supports a battery within the battery pack. A first joint flange that is joined to a case bottom portion of the side frame is arranged such that a second joint flange that is joined to the case bottom portion of the battery frame overlaps an upper side in an upward-downward direction of the first joint flange.

Abstract: A vehicle body lower part structure includes: a side frame that connects a battery pack which is arranged below a floor panel of a vehicle to a side sill which is provided at a further outer position in a vehicle width direction than the battery pack; a lower cross member that is provided within the battery pack, is arranged between batteries, and extends in the vehicle width direction; and a connection portion that is provided within the battery pack and connects the lower cross member to the floor panel. The connection portion is provided at a further outer position in the vehicle width direction than the batteries.

Abstract: A plasma accelerating apparatus includes: a cathode (11) configured to supply electrons to a plasma acceleration region; an anode (12); a power supply (13) configured to apply a voltage between the cathode and the anode; a supply port (14) arranged on an outer circumference side of the cathode to supply a propellant to the plasma acceleration region; and a first magnetic field generator (15) configured to generate a first axial direction magnetic field in the upstream side region of the plasma acceleration region to suppress electrons supplied from the cathode from heading for the anode. Thus, the plasma accelerating apparatus and the plasma accelerating method having high thrust efficiency is provided.

Abstract: An anti-stress agent and functional food containing the anti-stress agent and having an anti-stress effect, which contain as an effective ingredient fermented sour milk prepared by, for example, fermenting animal milk starting material with lactic acid bacteria of the genus Lactobacillus, which can be taken repeatedly and daily without any problems with safety, and which can mitigate and prevent mental and physical symptoms caused by stress.

Abstract: A physiologically functional food having brain function-improving, learning ability-enhancing and memory-enhancing functions, which comprises as an active ingredient a lactic acid bacterium fermented milk, a lactic acid bacterium and yeast co-fermented milk, or a treated product thereof, or a mixture thereof, optionally also including a pharmaceutically or nutritionally acceptable carrier or diluent.

Abstract: A nozzle extension mechanism for a rocket engine is applied to an engine in an upper stage rocket in a multi-stage rocket. Since a high expansion nozzle to be used in the upper stage rocket engine is long, the rocket is divided at a nozzle portion in view of volume efficiency. The nozzle portion is retracted and received around the upper stage rocket engine and is shifted to a high altitude space. The nozzle portion is assembled for use prior to operation. For this reason, in order to bring the nozzle portion from the retracted condition to the operative condition, it has been necessary to use a drive source, a power device or a shifting device for shifting the nozzle portion. This leads to a weight problem. The devices left in the upper rocket adversely affect the payload. This is resolved by using a fastening portion provided at a rear end of the high expansion nozzle that is received by and then separated from a coupling mechanism provided at a front end portion of the lower stage rocket.

Abstract: A magnetic recording medium which comprises a base material and a magnetic layer provided thereon. The magnetic layer comprises magnetic particles, a cellulose resin and a polyurethane resin as the binders and .alpha.-Fe.sub.2 O.sub.3 particles, whereby the dispersibility of the magnetic particles in the magnetic layer is enhanced without deterioration of the durability of the magnetic layer.
