  • Ion implantation apparatus capable of avoiding electrification of a substrate
    Patent number: 4994674
    Abstract: In an ion implantation apparatus which is for use in injecting an ion beam (11) onto a wafer (12) in a predetermined direction and which comprises an electric conductor tube (14) divided into a first tube section (17) and a second tube section (18) along the predetermined direction with an insulator interposed therebetween. The first tube section is located in proximity of the wafer and is grounded while the second tube section is remote from the wafer to be used as a target section which is bombarded by primary electrons to generate secondary electrons directed to the wafer. Undesired electrons are trapped by the first tube section and flow through the ground.The electric conductor tube may further comprise a third tube section (21) which is electrically insulated from the second tube section and which is remote from the wafer in comparison with the second tube section in the predetermined direction.

  • Device with a thrust bearing
    Patent number: 4970422
    Abstract: A rotatable element is arranged on a supporting member.

  • Personnel door for a RF shielded room
    Patent number: 4953324
    Abstract: A personnel door for sealing a room having a source of Radio Frequency (RF) radiation. The door when swung into a closed position can be energized to be partially disposed in an opening below floor level directly beneath the door. Sealing between the door and the door frame of the room can occur around the borders of the door including the part disposed in the opening below floor level. A step up into the room or use of a ramp to gain access to the room is thereby eliminated. In the preferred embodiment, the door is retained above the opening below floor level by springs and energized to move vertically downward into the opening against the force of the springs by an air cylinder.

  • Dew point analyzer
    Patent number: 4946288
    Abstract: The dew points of condensible hydrocarbon and water in a gas stream are determined independently in a single run by observing changes in intensity of light scattered from a mirror surface which is cooled to below both of the dew points. A decrease in intensity denotes the hydrocarbon dew point while an increase in intensity denotes the water dew point. The apparatus is simple and operates automatically. The mirror surface has a first polished and highly reflective portion and a second, roughened, less reflective portion. The intensity of scattered light is preferably monitored separately for each mirror portion.

  • Bradykinin antagonist peptides
    Patent number: 4923963
    Abstract: The substitution of the L-Pro at the 7-position of the peptide hormone bradykinin or other substituted analogs of bradykinin with an aliphatic, cyclic or aromatic amino acid of the D-configuration converts bradykinin agonists into a bradykinin antagonist. The invention further includes additional modifications at other positions within the novel 7-position modified bradykinin antagonists including C-terminal and N-terminal extensions and replacement of arginine in the one and nine positions which increase enzyme resistance, antagonist potency and/or specificity of the new bradykinin antagonists. The analogs produced are useful in treating conditions and diseases of the mannal and human body in which an excess of bradykinin or related kinins are produced or injected as by bites into the body.

  • Ion implanting apparatus
    Patent number: 4914292
    Abstract: In an ion implanting apparatus equipped with an electron shower for neutralizing the positive charge-up by the ion implantation with electrons, an electrically conductive tube is disposed just before the workpiece to be ion-implanted to pass through an ion beam which has a diameter nearly equal to the inner hollow channel of the tube section to absorb those electrons which do not overlap the positive ion beam, and a flange section extends substantially parallel to the surface of the workpiece to absorb the secondary electrons emitted from the ion implant portion thereby suppressing the negative change-up around the ion implanted portion.
