Abstract: Lamp units for radiating a beam ahead of a vehicle in a light distribution pattern are housed in a lamp body. Illumination of the auxiliary lamp units is controlled based on driving conditions. Illumination control means extinguish light through dimming by gradually decreasing voltage applied to the light sources. When the applied voltage has dropped to a threshold value, the applied voltage is controlled to zero immediately. Compared to when the lamps remaining in an illuminated state are suddenly extinguished, a change in quantity of light is mild, and no uncertainty arises. Below a threshold value where the applied voltage gradually drops to the threshold value and a change may arise in the filament crystalline structure due to annealing at a transition temperature, the applied voltage approaches zero. Hence, the filament does not pass from the transition temperature while being rapidly cooled, thus avoiding filament crystalline structure change.

Abstract: In a reforming method for a high temperature type fuel cell in which dimethyl ether is used as fuel gas, and a gas containing hydrogen and carbon monoxide produced by reacting dimethyl ether with carbon dioxide is fed into the anode, the carbon deposition at the time of reforming is prevented. The feeding amounts of dimethyl ether and carbon dioxide from a pipe h1 into the reforming reactor are regulated in such a way that the relation between temperature inside the reforming reactor and the molar ratio of carbon dioxide to dimethyl ether in the reforming reactor falls within the region C.

Abstract: A base end 12a of an arc tube unit 12 is inserted in a glass tube 50 which is previously fixed to an insulating plug unit 14, and a shroud tube 18 and the glass tube 50 are then bonded and fixed to each other in such a state that an amount of insertion of the arc tube unit 12 is regulated in order to set a dimension L between an optical reference plane Po of the insulating plug unit 14 and the tip position of a bar-shaped electrode 26B of an arc tube 16 to be a predetermined set dimension Lo. Consequently, the arc tube unit 12 can be fixed and supported on the insulating plug unit 14 with a simple structure in a simple process, and furthermore, it is possible to eliminate a possibility that the shroud tube 18 might be damaged, for example, broken by the fastening force of a metal band as in the conventional art.

Abstract: The present invention is to provide a novel medicine, drink, food or feed having an action of strengthening bone. More specifically, the present invention is to provide a medicine, drink, food or feed combined with collagen, fraction containing collagen or degradation product thereof. Fraction containing collagen was prepared by mincing skin corium layer into pieces, defatting it and lyophylization or by pulverizing bone, decalcifying it and lyophylization. Oral administration of these can stimulate proliferation of osteoblast, inhibit bone resorption and strengthen bone. They can be useful for improvement of osteoporosis, bone fracture, bone pain, etc.

Abstract: The present invention provides a basic protein and a basic peptide composition which can be administered orally and has the ability to stimulate osteoblast proliferation, strengthen bone and inhibit bone resorption. Said basic protein has the following properties: (1) a molecular weight distribution of is 2,000-24,000; (2) an isoelectric point distribution of is 7.5-11; and (3) it is comprised of more than 10% of basic amino acids. Said composition can be obtained by the following steps: After milk, or raw material derived from milk, is loaded onto a cation exchange resin column, a fraction is obtained by eluting with an eluent of 0.1-1.0M salt concentration, precipitate removed by (i) heating to over 75.degree. C., (ii) by adding alcohol so that the final concentration thereof is 10-50% or (iii) by adding salts so that the final concentration thereof will be more than 0.2M; and the supernatant thereof containing the basic protein fraction recovered.

Abstract: A bone reinforcing agent comprising a basic protein fraction or a basic peptide fraction derived from milk as an effective component is described. The basic protein fraction is obtained by passing milk or a raw material derived from milk over a cation exchange resin and eluting the adhered fraction. The basic peptide fraction is obtained by hydrolyzing the basic protein fraction with a protease. The basic protein fraction and basic peptide fraction of the present invention promote the growth of osteoclasts and suppress the resorption of osteoclasts, and thereby strengthening bone when administered orally. The invention is useful for treating or preventing bone diseases such as osteoporosis.

Abstract: A magnetohydrodynamic power generator is provided in the cathode wall constituting one part of its generating channel with an oxidizing agent injection device. By supplying oxidizing agent to the surface of cathodes through this injection device, the reducing atmosphere in the vicinity of the cathodes is neutralized, thereby preventing short-circuiting between adjacent electrodes.
