  • Patent number: 8884152
    Abstract: A metal mixture is prepared, in which an excess amount of Te is added to a (Bi—Sb)2Te3 based composition. After melting the metal mixture, the molten metal is solidified on a surface of a cooling roll of which the circumferential velocity is no higher than 5 m/sec, so as to have a thickness of no less than 30 ?m. Thus, a plate shaped raw thermoelectric semiconductor materials 10 are manufactured, in which Te rich phases are microscopically dispersed in complex compound semiconductor phases, and extending directions of C face of most of crystal grains are uniformly oriented. The raw thermoelectric semiconductor materials 10 are layered in the direction of the plate thickness. And the layered body is solidified and formed to form a compact 12. After that, the compact 12 is plastically deformed in such a manner that a shear force is applied in a uniaxial direction that is approximately parallel to the main layering direction of the raw thermoelectric semiconductor materials 10.

  • Patent number: 6560650
    Abstract: When a failure is occurred in the Internet or a connection between a computer system and an Internet provider, a reconnection is performed automatically, and data are resent. Hence, a restoring operation can be made easily. Further, even when long data are re-transferred, a reliability can be ensured. When a receiving computer and the Internet provider are disconnected and reconnected, a sending computer receives an old IP address and a new IP address of the receiving computer, and compares the received old IP address and an old IP address stored in a connection information storage. When the IP addresses are matched, the data are re-transferred to the receiving computer by using the received new IP address.

  • Patent number: 5458681
    Abstract: A pigment or extender pigment treated with a linear reactive alkylpolysiloxane having in the molecule amino groups, imino groups, halogen atoms, hydroxyl groups, or alkoxyl groups, which is oriented and adsorbed to the surface of the pigment or extender pigment by heat treatment; a process for producing the treated pigment; and a cosmetic made with the treated pigment. The alkylpolysiloxane has a degree of polymerization from 25 to 100 and a Mw/Mn ratio from 1.0 to 1.3. The organosilicon-treated pigment, characterized by silicone firmly adsorbed to its surface, freedom from residual hydrogen, very smooth feel, good adhesion to the skin, and ability to permit color pigment of fine particle size to spread well, is particularly suitable for use in cosmetics such as powder foundation, liquid foundation, rouge, and eye shadow.

  • Patent number: 5159287
    Abstract: A high efficiency RF power amplifier includes a field effect transistor having a grounded source, a gate receiving an input signal, and a drain. A first inductor has a first end coupled to the drain via a lead inductance, and a second end through which an amplified output signal is output. A first capacitor has a first end grounded and a second end coupled to the second end of the first inductor. A second inductor has a first end receiving a drain bias voltage and a second end coupled to the second end of the first inductor. The second inductor is formed of a distributed-constant element. The first capacitor and the second inductor form a parallel resonant circuit coupled to the drain at a fundamental operating frequency of the high efficiency RF power amplifier, so that the drain is set to a high-impedance state.

  • Patent number: 5091013
    Abstract: A pigment (or body) composed of particles having surfaces covered with a high molecular substance containing a group of the formula --COOR, where R stands for a hydrogen or metal atom, and having an acid value of at least 200 when the R in the formula stands for a hydrogen atom. It has a high power of absorbing and holding moisture. The surfaces of the pigment particles are alternatively covered with both such a high molecular substance and a substance which makes the surfaces hydrophobic. This pigment has a good affinity for oil and yet a high power of absorbing and holding moisture. A cosmetic containing any such pigment has a high moisturizing power and provides a long makeup life.
