Title: Packing and method for producing the same
Inventor: UEDA TAKAHISA
IPC: F16J15/22
Filed: 1991-02-26
Granted: 1998-11-24
Abstract: The packing according to the present invention is composed of a string-like body in which a tape-like packing material having at least one layer is folded in the thickness direction thereof in zigzags with mountain portions and valley portions alternately formed. According to the packing, the string-like body cut into a predetermined length according to the diameter of a shaft concerned may be wound on the outer peripheral surface of the shaft with the width or thickness direction of the string-like body directed in the radial direction of the shaft. Thus, the packing is versatile with respect to the shaft diameter. The packing itself produces no slip in the axial direction of a shaft concerned. This prevents the packing from protruding, thus eliminating the release of stress due to decrease in volume. The packing is used with the string-like body folded in the three-dimensional directions. Accordingly, the shaft-following properties of the packing at the time when the same is worn, are satisfactory and the decrease in sealing properties is restrained.

Inventor: GARDNER JEFFREY G
IPC: B24C5/04
Filed: 1991-04-25
Granted: 2001-12-18
Abstract: The invention is a nozzle unit designed for use with wet abrasive materials to clean hard surfaces, such as steel structures. The nozzle unit is formed from two nozzle bodies, which are joined together. Each body has a lengthwise bore therein, with a venturi structure, and a metallic liner is fitted into each bore. Inside the nozzle unit is an annular cavity, which is connected into a source of water and a mixing chamber. The nozzle unit also has air passages therein that connect the mixing chamber with air surrounding the nozzle unit. In a wet blasting operation, an abrasive material, such as sand, is directed into the mixing chamber, where it mixes with water and air to form a wet abrasive stream.      The wet stream is then discharged from the nozzle onto the structure to be cleaned.

Title: Method of monitoring cellular radio channels to avoid adjacent and co-channel interference
Inventor: CHAPLAIN EUGENIE MARIE
IPC: H04W72/08
Filed: 1990-11-07
Granted: 1998-12-01
Abstract: A method to enhance the quality of cellular radio service is disclosed.  Only those channels that have a reduced likelihood of co-channel or adjacent channel interference are allocated.  This technique, in addition, allows information to be provided to the operating company of drawbacks with the currently engineered RF environment.  In particular, the base station will scan for RSSI readings on its channel and channels adjacent to it.  If a RSSI measurement above a predetermined threshold is detected, it is assumed that the base station is intercepting a signal from a mobile that is presently being served by another voice channel on an adjacent cell.  If this base station were selected to process a call, it may interfere with the call that is already in progress on the current channel or a call that is in progress on an adjacent channel.  The base station will inform the controller when it detects a RSSI reading above the predefined threshold indicating that the possibility for co-channel and adjacent interference exists.  It will also inform the controller when the detected RSSI reading has gone back below the predefined threshold indicating that the possibility for co-channel and adjacent interference has ceased.  If an idle voice channel reports the possibility of co-channel or adjacent interference, it will not be chosen to process a call until all other voice channels that are not reporting interference are in use.  When the voice channel reports that the possibility for co-channel or adjacent channel interference has ceased, it will be returned to its normal priority level to be selected to process a call.

Title: Time constant detecting circuit and time constant adjusting circuit
Inventor: ICHIHARA MASAKI
IPC: G01R27/00
Filed: 1992-12-16
Granted: 1996-12-03
Abstract: The present invention is a time-constant detecting circuit incorporated in a LSI, for detection of the variations of component values of resistors and capacitors in the LSI as the variations of a time constant. A pseudo-resistor iscomposed of a switched-capacitor circuit. Two analog switches are switched on and off alternately in a period T to control charging and discharging of a capacitor. With the operation of the capacitor having a capacitance C, there is formed a pseudo-resistor of a resistance Rp = T/C. A predetermined DC voltage Vout is divided bya series circuit of the pseudo-resistor and an ordinary resistor, and is smoothed by a second capacitor. Output voltage Vout, smoothed and allowed to appear at the output terminal, is uniquely defined by a time constant  = 1/RC, so that the variations of the time constant formed with the resistors and capacitors in the LSI can be detected by a measurement of the output voltage Vout.

IPC: C23C14/06
Filed: 1994-10-03
Granted: 1999-02-16
Abstract: A high performance, durable sputter coated, heat-treatable glass which after heat-treatment exhibits about 76% or more visible transmittance, a hemispherical emissivity (E h) of about 0.16 or less, and a normal emissivity (E n) of about 0.12 or less is formed by sputter coating a layer system on a glass substrate which includes an undercoat and overcoat of Si3N4, a silver layer, and two nickel or nichrome layers on opposite sides of the silver layer, and wherein the lower nickel-based layer is about three times as thick as the other nickel based layer.  The increased thickness of the lower nickel-based layer allows the coated glass article to be both heat-treatable, and "low-E' after the heat-treatment.          This allows matching with other known glasses in the family of layer components by way of the heat-treatment process.  The layer system employed allows, even if not matchable to another glass, for the sputter coating operation to include the coating of other members of the family of coating without change of targets, efficient use of the coater targets that exist, and minimal operational changes during production.
