Abstract: HERMETIC PACKAGE FOR AN ELECTRONIC DEVICE    AND METHOD OF MANUFACTURING SAME    Abstract of the Disclosure A  hermetic  package  for  an  electronic  device  is manufactured by providing a green glass ceramic body with a green via to produce a workpiece.  The workpiece is sintered  at  a  temperature  at  or  above  500°C,  while compressing the workpiece at a pressure at or above 100 pounds  per  square  inch,  so  as  to  obtain  a  hermetic package. The green via comprises a mixture of copper and a glass ceramic material with a sufficient volume of glass to produce a hermetic package, yet with sufficient copper to have a suitable electrical conductivity.     The  hermetic  package  thus  produced  comprises  a sintered  glass  ceramic  body  having  an  electrically conductive sintered via which is hermetically bonded to the glass ceramic body and which comprises a mixture of an electrically  conductive  material  and  a  glass  ceramic material.  The electrically conductive material forms at most 50 volume percent of the via.     The workpiece may be sintered in a sintering fixture having a frame and a compensating insert. The compensating insert  and  frame  bound   a   sintering  chamber   for accommodating the workpiece. By providing a frame having a thermal expansion coefficient greater than that of the workpiece, and by providing a compensating insert having a thermal expansion coefficient greater than that of the frame, a close fit can be assured between the workpiece and  the  sintering  fixture  over  a  large  range  of temperatures.

Abstract: A blow molded, plastic, bag tossing game for use by one or more players can be disposed in either a transportable mode, a display mode, or a playing mode. In the playing mode a pair of identical, modular target assemblies are deployed in spaced apart relationship to present a pair of slightly inclined, apertured targets towards which soft bags are thrown to generate points in accordance with rules. Each target assembly comprises a resilient, generally rectangular plastic playing board which includes a target aperture. Each target board is inclined for play by two elevator trays which are pivotally coupled to each board. For storage each elevator tray can be folded into position on the underside of the target board. The bags are captivated during storage within sunken orifices defined in the boards. The orifices define reinforcement means, which brace the apparatus and obviate separate right angled struts. Pins projecting from each board penetrate suitable orifices defined on the opposite board to facilitate snap fitting. The boards may be fitted together to maintain a sleek, overall low profile. Handles project from recessed notches defined in each playing board. A recessed external surface defined in said playing board for receiving an apertured insert for displaying an advertisement.      The larger elevator tray comprises a recessed circle for registering with the target aperture when the game is disposed in the transportable position for displaying the remainder of the advertisement. Hook means are provided for nan-destructively reversibly flush mounting the game.

Granted: 2002-11-05
Abstract: A compacting device for waste, in particular for compressible garbage, which has a compacting piston and a compacting shield in the lower part of a receiving chamber for the garbage which is present in the housing of the device.

Title: Method for determining electromagnetically the locations of underground conductive bodies
Inventor: HOLMQVIST SVANTE
IPC: G01V3/10
Filed: 1991-12-10
Granted: 1995-11-07
Abstract: The invention relates to a method of determining elec-tromagnetically the locations of electrically conductive bodies beneath the surface of the ground, wherein a primary electromagnetic field is generated with the aid of a loop through which a sinusoidal alternating current is passed.  The loop is placed at or above the level of the ground beneath which the locations of conductive bodies shall be determined.  There are generated in the conductive bodies currents which, in turn, generate a secondary electromagnetic field, wherein the values of the amplitude and phase of the magnetic component of the thus formed total electromagnetic field are measured in three linear independent directions with the aid of coils mounted inside a probe which is lowered to differ-ent depths in a borehole which extends down into the ground within the propagation area of the primary field. The measured values are transmitted through a transmis-sion line to a receiver, as are also the values for determining the phase of the primary field, so as to enable the phase difference between the primary field and the total field to be calculated.  This difference is used to determine the three real and three imaginary components of the secondary field, these components in turn being used to determine the location of the conduc-tive bodies.  The invention is characterized in that the values of the primary field phase are measured continu-ously by at least one reference coil which is placed outside the probe, either above or beneath the surface of the ground, within the propagation area of the prima-ry field.  the reference coil is orientated so as to re-ceive at least one component of the magnetic field and the signals obtained from the reference coil, or the result of processed signals, are transmitted to the receiver on a transmission line.

Title: Disturbance isolation in a belt receptor of a color printer
Inventor: CASTELLI VITTORIO R
IPC: G03G15/01
Filed: 1992-09-16
Granted: 1997-08-19
Abstract: A belt receptor module for a color printer isolates disturbances such as impulsive and high-frequency force disturbances caused by entrance of a recording medium into a transfer nip of a transfer station.  The belt receptor module includes a belt receptor positioned about a plurality of spaced rollers.  A transfer station is located adjacent an area of the belt receptor.  A tension roller is located adjacent the belt receptor on either side of the transfer station.  The tension rollers each articulate about an appropriate axis to enable the belt receptor to enter a subsequent roller at an angle of approximately 90° to its axis without generating lateral forces.  Each tension roller is movable along a different line to create a tension level therein, each tension level being different from the other tension level.  The tension levels generated by the tension rollers do not substantially change with the position of said rollers and, thus, providerelief from the impulsive and high-frequency force disturbance caused by the entrance of a recording medium into a transfer nip of the transfer station.  Theisolation of the disturbance enables proper registration of the color separations while avoiding motion-induced artifacts.

Title: Apparatus for measuring a distance between two running vehicles using light wave
Inventor: OHMAMYUDA YUKIO
IPC: G01S17/931
Filed: 1992-12-14
Granted: 1998-04-21
Abstract: To measure a distance between two running vehicle, a measurement signal is first generated by irradiating light beam toward an article to be measured and then receiving the reflected light beam from the article.  An apparatus for determining the forgoing distance therebetween using light wave operates such that a reference signal and the measurement signal generated in that way are input a digital mix-down circuit composed of two-stage flip-flop circuits to determine a phase difference between the reference signal and the measurement.  The apparatus includes as essential components a clock delay circuit for delaying the going-high edge of the measurement signal while the reference signal is going high at an output terminal of a flip-flop circuit on the input side of the digital mix-down circuit and a data delay circuit for delaying the going-down edge of the reference signal input into a data terminal of the flip-flop circuit.  Usually, the clock delay circuit is electrically connected to the digital mix-down circuit via the data delay circuit, while the data delay circuit is electrically connected directly to the digital mix-down circuit.  Alternatively, both the clock delay circuit and the data delay circuit may electrically be connected directly to the digital mix-down circuit.
