  • Patent number: 11912284
    Abstract: An alighting assistance device D of the present disclosure may be a device moving a driver seat rearward in a case where a determination may be made that an occupant seated on the driver seat of a vehicle alights. The device may include a height changer which changes a height of a steering wheel, a sitting height acquirer which acquires a sitting height of the occupant, and a steering wheel controller 33 as one example of a height controller which controls the height changer such that the height of the steering wheel becomes lower as the sitting height acquired by the sitting height acquirer may be higher in the case where a determination is made that the occupant alights.

  • Publication number: 20140225303
    Abstract: This invention relates to a medicinal composition, which rapidly disintegrates when taken in the oral cavity and shows sufficient hardness upon production, distribution and use in usual manner, can be obtained by adding, to a sugar alcohol and/or saccharide, a sugar alcohol and/or saccharide having a lower melting point than the first-mentioned sugar alcohol and/or saccharide and then subjecting the resulting powder to combined processing of compression and heating. This invention can provide medicinal compositions, which rapidly disintegrate when taken in the oral cavity without water and are excellent in handling ease owing to exhibition of sufficient hardness upon their production, transportation and use in usual manner, and can also provide a process for the production of the medicinal compositions, which is simpler and can avoid contact between an active ingredient and water as needed.

  • Publication number: 20090062404
    Abstract: The present invention provides an intraoral rapid-disintegrating pharmaceutical composition which exhibits excellent intraoral disintegrating property and high hardness, and which can be applied, in particular, to a pharmaceutically active ingredient which is unstable in water. The pharmaceutical composition, which contains lactose and powdered cellulose, exhibits high hardness without prolongation of its intraoral disintegration time. When a disintegrating agent is further incorporated into the pharmaceutical composition, the hardness of the composition is increased without prolongation of its intraoral disintegration time. When magnesium aluminometasilicate, and one or more species selected from among silicic acid and silicic acid salts other than magnesium aluminometasilicate are further incorporated into the pharmaceutical composition, the composition exhibits higher hardness without prolongation of its intraoral disintegration time.

  • Patent number: 6335036
    Abstract: A granular pharmaceutical preparation prepared by granulating finely powdered Ebselen(2-phenyl-1,2-benzisoselenazol-3(2H)-one) using a hydrophilic polymer, and an aqueous suspension thereof. The Ebselen granular pharmaceutical preparation of the present invention is excellent in its performance as an oral preparation for use in stomach tube administration. That is, since it can be dispersed easily and uniformly when suspended in water or an aqueous solution before its use, and the suspension can be maintained in excellent dispersed state, preparation and tube administration of the drug solution can be made easily. Also, its dose is accurate because the administration can be effected with no drug or drug solution remained in the tube after the administration. In addition, the granular pharmaceutical preparation of the present invention is also suited for its large scale production, because it can be produced without employing special apparatuses and production steps.

  • Patent number: 5676927
    Abstract: The present invention relates to a granular preparation for MRI obtained by granulating a viscosity-increasing agent together with a binder and if necessary, a vehicle, a disintegrant, etc., by the use of a fluidized-bed granulation method, and spraying ferromagnetic particles suspended in an aqueous solution of a viscosity-increasing agent or a binder for coating the granules or incorporating the suspension into he granules at the time of granulation to prepare bulky granules. The granular preparation according to the present invention does not undergo coagulation due to gelling at the time of suspending, and can be instantaneously turned into a suspension which is uniform and viscose by mere stirring. Accordingly, the preparation method is simple and easy.
