Granted: 1999-10-05
Abstract: There is disclosed a precious metal article which is formed of a solid-phase sintered product of a precious metal powder.      For manufacturing the precious metal article, a moldable mixture which contains a precious metal powder and a binder removable by sintering is shaped into a prescribed molded object, and the molded object is then subjected to sintering. The moldable mixture is produced by preparing a precious metal powder, preparing a jellylike cellulose binder by blending a cellulose with water and leaving for a prescribed period of time, and blending the precious metal powder and the jellylike cellulose binder together. The most preferable moldable mixture contains 50 to 90 % weight of precious metal powder, 0.8 to 8 % by weight of water-soluble cellulose binder, 0.08 to 3 % by weight of a surface-active agent. 0.1 to 3 % by weight of oil, balance water and unavoidable impurities. The precious metal powder preferably contains gold powder and powder of an alloy containing silver or copper, and the gold powder is obtained by submerged-reduction method.

Title: Liner for a split seat gate valve
Inventor: OWENS BRIAN S
IPC: F16K3/02
Filed: 1991-05-31
Granted: 1994-10-25
Abstract: A gate plate assembly (20) has two aligned and connected body housing members (26) which each have a gate slot above a through passage which is above a seat portion slot. Gaskets (30) are compressed by the body housing members (26) to form a liquid-tight seal along the valve sides. Two resilient valve liners (24) are fitted between and compressed by the body housing members (26). Each valve liner (24) has a body with a planar front face (40) and a cylindricalthrough passage (44) which extends through the liner body. A seat portion (64) extends downwardly from the body of each liner (24) and increases in thickness as it extends from the body. The valve liners (24) are compressed within the body housing members (26) such that the planar front faces (46) are adjacent one another and the seat portions (64) are compressed within the seat portion slots (80) to produce a tight seal along the bottom of the valve assembly (20). A packing filled chamber (100) at the top of the assembly forms a tight seal at the top of the valve. An imperforate gate (22) is slidable through the gate slots toalternatively obstruct and permit fluid flow through the valve (20). The seat portions (64) extend to the bottom of the valve such that particles trapped between the seat portions (64) may be expelled form the valve between the seat portions (64).

Title: Multiple probe electrode arrangement for scanning tunnelling microscope recording and reading
Inventor: TAKIMOTO KIYOSHI
IPC: G01Q10/00
Filed: 1992-07-15
Granted: 1999-10-19
Abstract: An information recording/reproducing method and apparatus is for carrying out at least one of recording and reproducing information through a probe electrode or through a plurality of probe electrodes an an information recording medium. A probe electrode is disposed on an elastic member. A relative position is so adjusted between the recording medium and the probe electrode that a repulsive force between them is comparative to an elastic force of the elastic member.      In case of plural probe electrodes, they are displaced to keep an equal spacing between the recording medium and the respective probe electrodes so that they may have either a zero average or a minimized square sum of displacement. A spacer layer will do for setting a spacing between a probe electrode and the recording medium.

Filed: 1992-10-02
Granted: 2000-12-12
Abstract: The center of a collet having a plurality of individual gripper members resiliently spaced apart in an annular array and operated on by a frustoconical surface can be adjusted by displacing some of the gripper members more than others of the gripper members parallel to the axis with which both the annular array and the frustoconical surface are nominally concentric.      This causes the frustoconical surface to produce greater radial displacement of some of the gripper members, thereby shifting the center of the collet transverse to the above-mentioned axis. An element transversely moveable relative to the axis causes displacement of some of the gripper members more than others.

Granted: 1998-12-29
Abstract: In an electric cable or other elongate body, a tubular textile braid comprises two sets of yarns each made up of a plurality of synthetic monofilaments, the yarns of the two sets extending in opposite directions around the axis of the braid (and so corresponding to upper and lower yarns in the braiding machine) differing in twist to an extent such that the more twisted yarns have their tensile strength increased by at least 10% but do not have their cover in the braid decreased by more then 25%, both by comparison with an otherwise identical yarn having the same twist of those of the less twisted set.  Preferably the twist in the upper yarns is zero.     The invention allows higher production speed and reduced down-time without significant loss of cover, because the small extra twist in the lower yarns gives them better abrasion resistance to withstand passage through their greater exposure in the braiding  machine.

Title: Method of and system for order amount calculation
Inventor: KANEKO KUNIYA
IPC: G06Q50/00
Filed: 1994-08-04
Granted: 1999-05-18
Abstract: An  order  amount of parts can be  calculated  from  an actually  used amount of the parts, so that the  used  parts can be resupplied subsequently.  An order amount can also be calculated  form  a  production  plan,  so  that the  parts necessary to meet the plan can be delivered.    In this technique, an order amount is calculated by the equation  "W1~X' + W2~X2", where X1 is  the order  amount calculated  in  a subsequently resupplying way,  X2 is the order amount calculated in a plan correspondence way, W1  is an  actual  weight,  and W2 is a plan  weight.   The  actual weight  W1 becomes high and the plan weight W2  becomes  low when the subsequently resupplying way is suitable, and  vice versa.   The actual weight W1 and the plan weight W2 can  be calculated from experience or system analysis.
