Abstract: An oral formulation comprising a biguanide and an organic acid has less unpleasant tastes such as bitterness and saltiness.

Abstract: There is provided a tablet preparation showing quick disintegratability in the mouth and good sensory acceptability and yet having an adequate strength to resist damage in the course of distribution. Each tablet comprises a starch, a water-soluble excipient and a medicament and does not substantially contain a binder other than starch.

Abstract: The present invention provides a compact and inexpensive air-permeable cap and an outdoor lamp, automobile lamp and automobile electrical component including such an air-permeable cap. A novel air-permeable cap is provided including a closed-end cylindrical cover member, a substantially cylindrical body fitted in the closed-end cylindrical cover member, and an air passage formed between the inner wall of the closed-end cylindrical cover member and the outer wall of the substantially cylindrical body and between the bottom surface of the closed-end cylindrical cover member and the lower end of the substantially cylindrical body, wherein the mounting portion at which the air-permeable cap is mounted on the mounting opening of the housing is formed at the top of the substantially cylindrical body.

Abstract: An air-permeable filter for ink cartridge is described, which comprises a laminate comprising at least one porous material layer comprising at least one resin selected from the group consisting of fluororesin and polyolefin resin and at least one air-permeable substrate layer having a tensile strength of 1 MPa or more. An ink cartridge is also described, which comprises a space for receiving an ink and at least one air vent in which the air-permeable filter is provided.

Abstract: The object of the present invention is to provide a member for EL devices permitting a production cost reduction and an EL device containing the same. A member for EL devices comprises a removing agent for removing a predetermined gas component and an adhesion member fixed to the removing agent.

Abstract: A member for an electroluminescent device is described, comprising a container a part of which is made of a porous material and a removing agent capable of removing a prescribed gaseous component, the removing agent being contained in said container. An electroluminescent device having the member is also described.

Abstract: A coating method which is characterized in that, when the surfaces of solid particles kept flowing are spray-coated with a thermally melted wax, a two-fluid nozzle adapted to mix a thermally melted wax with a heating gas in and eject the resultant mixture from one flow passage and eject a heating gas from the other flow passage is used, the two-fluid nozzle having spray ports of a diameter of 1.5 to 5.8 mm, and the two-fluid nozzle having no needle valve. According to this method, the use of an organic solvent for melting wax is omitted, and complicated operations for pulverizing a wax and for thermally melting the wax powder after it has been deposed on solid particles are not required. This method can also prevents clogging of the nozzle, powdering of the melted wax and forming of agglomerated solid, and permits simple and easy production of sustained release preparations and preparations for masking materials of unpleasant and bitter tastes.

Abstract: A device for detecting an edge of a transparent sheet of a laminated transparent and translucent sheet assembly, is provided which includes a light source for producing a shadow of the edge of the transparent sheet on a translucent sheet, a photosensor operative to produce an electrical output which varies depending upon variation of intensity of light supplied thereto, and a lens for producing a clear image of the shadow on the photosensor. A picture processing unit determines the position of the edge of the transparent sheet on the basis of a variation of the output of the photosensor.

Abstract: A multilayer coating film is provided on one side of a transparent or semitransparent glass plate to afford a golden appearance to the coated glass plate at least when viewed from the uncoated side. Essentially the multilayer coating film is made up of a TiN layer adjacent to the glass plate surface and either a Ti layer or a Cr layer which overlies the TiN layer, and the coating film is formed such that the transmittance of the coated glass plate for visible light becomes not more than 40%. Optionally, the Ti or Cr layer is overlaid with either a TiO.sub.2 film or a Cr.sub.2 O.sub.3 film. Also optionally, either a TiO.sub.2 film or a Cr.sub.2 O.sub.3 film is interposed between the TiN layer and the glass plate surface. Each layer of the multilayer coating film can be formed by sputter deposition using a relatively simple method, an the multilayer coating has good durability.

Abstract: The invention relates to an electrochromic (EC) display device which comprises a display electrode made up of a transparent conductive layer and a patterned EC layer, a counter electrode having an EC layer laid on a conductive layer and an electrolyte which occupies the space between the two electrodes, and in which the display electrode employs a first type EC material that takes on color in its electrochemically oxidized state, such as Prussian blue, and the counter electrode a second type EC material that takes on color in its reduced state, such as WO.sub.3, or vice versa. The EC layer of the counter electrode is not patterned, and the patterned EC layer of the display electrode is made smaller in surface area than the EC layer of the counter electrode and an upper limit of the surface area ratio of the former EC layer to the latter EC layer is specified.

Abstract: The invention relates to an electrochromic (EC) display device having a transparent electrode layer coated with a first EC material which takes on color in its electrochemically oxidized state, such as Prussian blue, and an opposite transparent electrode layer coated with a second EC material which takes on color in its reduced state, such as WO.sub.3. For use in initial bleaching or coloration of one of the two EC layers, an auxiliary electrode is disposed in a marginal region of the space between the two opposite electrodes, and an electrolyte occupies the remaining space. An insulating covering permeable to ions intervenes between the electrolyte and the body of the auxiliary electrode, and an insulating layer substantially impermeable to ions intervenes between the auxiliary electrode body and each transparent electrode layer or the overlying EC layer to prevent leakage current.
