  • Patent number: 10879144
    Abstract: A semiconductor package includes a semiconductor die including an active side, a redistribution layer over the active side of the semiconductor die, the redistribution layer including metal traces electrically connecting die pads on the active side of the semiconductor die to electrical contacts on an external surface of the semiconductor package, and a layered mold covering the semiconductor die opposite the redistribution layer. The layered mold includes a first resin layer adjacent to the redistribution layer, a fiber layer adjacent to the first resin layer and opposite the redistribution layer, and a second resin layer adjacent to the fiber layer and opposite the redistribution layer. A coefficient of thermal expansion (CTE) of the first resin layer is substantially different than a CTE of the second resin layer.

  • Patent number: 9505713
    Abstract: Provided are high purity sodium p-styrenesulfonate with an excellent hue which is useful as a reactive emulsifier or dispersant for producing a polymer emulsion, or synthetic starch for clothing ironing and poly(sodium p-styrene-sulfonate) with an excellent hue using the same or sodium p-styrenesulfonate improved in fluidity while keeping good solubility. An aqueous p-?-bromoethylbenzenesulfonic acid solution and an aqueous sodium hydroxide solution are reacted under specific conditions to control the particle size, thereby obtaining sodium p-styrenesulfonate particles improved in a balance between fluidity and solubility, and further, impurities such as isomers are reduced, thereby obtaining high-purity sodium p-styrenesulfonate with an excellent hue.

  • Patent number: 7191474
    Abstract: There is a demand for an automatic shampoo machine used in beauty solons and the like which dispenses with an all-purpose chair to be prepared separately and has a better appearance and an improved feeling of use. In an automatic shampoo machine 1, a seat 2 for seating a person to be shampooed thereon during shampooing and a basin 13 for receiving the person's head for the shampooing are supported by a common housing 3. The housing 3 accommodates and supports spout means 4 for spouting warm water automatically in the basin 13. Since the seat 2 is integrated in the automatic shampoo machine 1, the need for separately preparing a chair is obviated and the automatic shampoo machine 1 has an improved appearance. By using a space below the seat 2 effectively, functional components of the spout means 4 such as a warm water reservoir tank 45 are disposed in the space and the components can more flexibly be laid out.

  • Patent number: 7114201
    Abstract: An automatic shampoo machine used in beauty salons and the like, having improved operability and including a manual finish hair rinsing operation. A basin is provided with a hand shower and a hand shower valve to be operated by an operator standing behind, a hood for covering and uncovering the top of the basin and an open/close unit for opening/closing and moving the hood. The open/close unit guides the hood to a closing position, a first opening position and a second opening position. In the first position the hood is in an upright state behind the basin, and in the second position the hood is positioned on the left side of the basin. In the second position, the hood uncovers the rear side of the basin, whereby the operator can perform operations from the rear side of the basin without the hood interfering.

  • Patent number: 5906012
    Abstract: In an automatic shampoo machine a recess is formed in a side wall of a basin to ensure water passage to the nape of the neck of a person being shampooed. A plurality of neck support members each including a bent wire arrangement is provided in a spaced relation in the recess. With the neck resting on top portions of the neck support members, the nape of the neck is rinsed by water sprayed from a stationary nape rinsing nozzle, and movable lower nozzles, through the recess. A pad for receiving the neck resting thereon is releasably attached on a peripheral portion of the basin to prevent fatigue of the neck and splashing of rinse water. Thus, the person can have his hair and nape washed in a comfortable posture.

  • Patent number: 4773270
    Abstract: A pressure gage for indicating pressure and variations thereof of a physical variable being monitored. The gage is provided with a circular dial having on the face thereof a pheripheral marginal portion or border green in color and graduations disposed internally of the green peripheral border. A pair of movable arcuate opaque cover plates, each made as an arc of an annulus, are disposed coaxial with the dial and graduations on the face of the dial. The plates are movably mounted for positioning thereof selectively in a circumferential direction of the dial for partially covering the marginal peripheral portion or border of the face of the dial. The plates are positionable selectively so that two opposed ends thereof define a space therebetween so that a green area of the border, which defines a range of selected pressure graduations on the dial, corresponds therewith.
