  • Patent number: 6246564
    Abstract: An actuating device for a motor used in a power window of an automobile which can drive the motor reliably to open the window even when the automobile is submerged in water. This device has a simple configuration is relatively small and inexpensive. This activating device comprises a drive circuit for a motor which has first and second relays to allow electric current to flow so as to drive the motor in either the forward or reverse direction. The contact of the second relay, which drives the motor in one direction, is used in such a way that the contact forms a part of an electronic circuit for the magnetic coil of the first relay. When the second relay operates, the electric circuit for the magnetic coil of the first relay is closed off. This activating device can ensure that a power window will be opened even if the automobile is submerged, and the first and second relay are switched ON at the same time.

  • Patent number: 5942292
    Abstract: The present invention provides a spacer for a liquid crystal display which is excellent in light shielding properties, does not suffer from fading even after the lapse of a long period, thus being excellent in long-term reliability, and has satisfactory strengths and a liquid crystal display made by using the spacer. The above spacer is composed of colored fine particles prepared by copolymerizing a polymerizable anthraquinone dye having at least one ethylenically unsaturated bond in the molecule with an ethylenically unsaturated monomer component in an aqueous medium.

  • Patent number: 4340544
    Abstract: Rose oxide, which is an important olfactive compound valuable in the art of perfumery, is advantageously produced from citronellol through a novel synthetic route comprising(1) anodic alkoxylation of citronellol using as a supporting electrolyte an alkali metal aromatic sulfonate,(2) dealkoxylation of the resulting 2,6-dimethyl-3-alkoxyoct-1-en-8-ol in the presence of a palladium or nickel complex, and then(3) cyclization of the resulting dehydrocitronellol in the presence of an acid.

  • Patent number: 4338467
    Abstract: A process for preparing an arylacetaldehyde by reacting the corresponding arylmethyl halide with carbon monoxide and hydrogen in the presence of a cobalt compound and a basic reagent in a liquid medium, characterized in that the basic reagent is an alkali metal compound and the liquid medium is a solvent system chosen from nitriles and their mixtures with hydrocarbons, whereby the arylacetaldehyde can be produced in a good yield by the use of a small amount of the cobalt compound as the catalyst.

  • Patent number: 4317918
    Abstract: An alcohol is produced in a high selectivity with a good yield from the corresponding carboxylic acid by reducing the latter with hydrogen in the presence of a rhenium catalyst in the coexistence of an organic base. An arylacetic acid, which is included in the starting carboxylic acid, can be produced in an excellent yield from the corresponding aryl aldehyde by reacting the latter with carbon monoxide and water in the presence of rhodium or its compound and hydrogen iodide.

  • Patent number: 4259557
    Abstract: Rectangular electric contacts are produced by forming rectangular holes in base pieces, inserting into the rectangular holes contact pieces of a profile identical to the profile of the rectangular holes and pressing the portions of the contact pieces protruding out of the rectangular holes in the opposite directions. In consequence of the pressing, the contact pieces are laterally expanded to fill up the rectangular holes in the base pieces and the portions of the contact pieces protruding from the rectangular holes are crushed sideways to give rise to extended portions somewhat greater in size than the rectangular holes and similar in shape thereto. The extended portions serve as points of contact.

  • Patent number: 4044212
    Abstract: A strip of electroconductive material is perforated by I-shaped holes. Contact materials shaped to conform to said I-shaped holes are inserted in the holes and caulked. Then, the I-shaped contact materials are perforated across the middle thereof in conjuction with the adjoining portions of the electroconductive material so as to divide each contact material into two contacts separated by a contact gap formed therebetween. A leaf spring fitted at one end thereof with a movable contact intended for insertion into said contact gap is held in position, though not in an immobilized state, with the other end thereof simply inserted around the stem of a spring support. Terminals which are retained in their fixed relative position by means of a webbing interconnecting them are fastened with adhesive agent to a plastic case. After the fastening, said webbing is cut off.
