  • Patent number: 8415922
    Abstract: To provide a power tool which can supply electric power again from a battery even in a case where the supply of electric power from the battery is stopped by an over-discharge detection means. A power tool 1 includes an FET driving circuit 36 which permits the supply of electric power again to a motor 31 from a battery pack 2 in response to the turning-on of a trigger switch 33 even in the case where the battery pack 2 is placed in an over-discharge state and so the supply of electric power to the motor 31 from the battery pack 2 is stopped.

  • Patent number: 7413355
    Abstract: A light emitting module according to the present invention is characterized in that a light emitting device and a light-emission-side lens are held close to each other by a holding part extended from part of a stem in parallel with outgoing light of the light emitting device, and light emitted from the light emitting device is refracted. A single-fiber two-way optical communication module according to the present invention has the light emitting module and, in addition, collimate lenses close to an optical fiber and a light receiving device, and is characterized in that splitting of light to a light receiving module or coupling of light from the light emitting module is performed with parallel rays. Each of the collimate lenses condenses the parallel rays to an incident/outgoing end face of the optical fiber, condenses the parallel rays to a light receiving face of the light receiving device, and outputs, as parallel rays, outgoing light from the light emitting module.

  • Patent number: 6150547
    Abstract: This invention provides carbonic acid- and/or hydrogencarbonic acid-iron-hydrolyzates of casein complexes containing a large amount of iron, without causing precipitation after heating their aqueous solution or astringent taste and the processes for production thereof. The complexes of the present invention are prepared by (1) partial hydrolysis of carbonic acid- and/or hydrogencarbonic acid-iron-casein complexes with a protease or (2) mixing carbonic acid and/or hydrogencarbonic acid, iron and partial hydrolyzates of casein with a protease. These complexes are used favorably as food additives, raw materials of medicines or feed components due to their lack of precipitation by heating their aqueous solution, or astringent taste.

  • Patent number: 5932259
    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.

  • Patent number: 5634805
    Abstract: A card receiving/ejecting device having an excellent operability and free from malfunction. First and second card receiving/ejecting units are vertically arranged adjacent to each other for accepting first and second expansion cards, respectively, for expanding a function of an information processing equipment. First and second ejection buttons are vertically arranged adjacent to each other at the side of openings formed in a housing. The first ejection button is directly connected to a first ejection lever, while the second ejection button is connected to a second ejection lever via an intervening spring which has a smaller elasticity than that of a second spring for urging the second ejection lever in a card inserting direction.
