Title: Tv game machine
Inventor: INOUE YOSHIHIRO
IPC: H05K5/00
Filed: 1991-08-15
Granted: 1999-05-04
Abstract: A locking groove extending in the horizontal direction is formed approximately at the center of a front surface of a cartridge.  A power switch is turned on/off in response to an operation of a slide switch.  When the power switch is turned on by the slide switch, a lock plate rotates in response to the operation of the slide switch.  At this time, a projecting portion provided on one side of the lock plate is fit in the locking groove.          Consequently, simultaneously with the turning on/off the power, the cartridge is locked so as not to be ejected.

Patent CA-2059349-C (CA)
Title: Energy transfer unit for a pile driver
Inventor: BERMINGHAM PATRICK
IPC: E02D13/10
Filed: 1992-01-14
Granted: 1997-11-18
Abstract: An energy transfer unit is designed for use in conjunction with a pile driving that has an impact block projecting from the lower end of the hammer casing and axially movable therein for transmitting energy from the hammer to a pile to drive the pile.          The unit comprises a housing for rigid attachment in axial alignment with the casing of the hammer, the  housing receiving and guiding the projecting portion of the pile driver impact block for axial movement therein.  A striker plate is guided for axial movement in the housing and is adapted to be impacted by the impact block and to transfer and distribute the impact force from the pile driver evenly and directly to the head of the pile.  Cushioning rings within the housing prevent impact between said striker plate and the pile driving hammer housing upon rebound of the pile, and thus prevents damage to the pile driver.  The cushioning rings are formed of rubber and are carried at the upper end of the housing by a retainer ring which is engaged by the striker plate when it rebounds.  Thus the rebound energy is absorbed by the rubber rings.

Title: Microwave apparatus and method for measuring fluid mixtures
Inventor: SCOTT BENTLEY
IPC: G01N22/04
Filed: 1990-07-02
Granted: 1999-01-19
Abstract: Apparatus for measuring the concentration of one material such as water in another material such as crude or refined oil including a coaxial microwave transmission line (14) formed by a conduit for receiving the material and a center conductor (22) which is sheathed with a dielectric covering  (27) which is operable to prevent short circuiting of the transmission path.   An oscillator circuit (30) is coupled to the transmission line and is driven by a free-running voltage controlled oscillator and a signal receiver monitors the change in frequency caused by impedance pulling of the oscillator due to the change in the dielectric constant of the mixture. Incident and reflected or transmitted power with respect to the measurement section is measured to determine whether an oil-in-water or water-in-oil emulsion is present to verify the concentration of one fluid in the other for a particular operating frequency.

Title: Optical magnetic disk recording/reproducing apparatus
Inventor: AOKI KAZUHIRO
IPC: G11B7/13
Filed: 1992-07-23
Granted: 1996-03-26
Abstract: Disk recording/reproducing apparatus has a first switch that outputs, during operation in the reproducing mode, the address signal and data signal alternately, and during either the recording or erasing mode, a reference voltage.  A second switch outputs, during the address signal period, the address signal obtained from a amplifier, and, during the data signal period, the output signal obtained from the first switch. Thus, during the recording or erasing mode of operation, the second switch will not produce the data signal.  The invention has the advantage of avoiding the previous need for an automatic gain control circuit in such apparatus.

Title: Suspension and shock absorber system for vehicles and trailers
Inventor: STEVENS DAVID B
IPC: B60G11/18
Filed: 1993-03-03
Granted: 1996-03-26
Abstract: The suspension system is a cartridge-type having an axle tube, a central tube and an anti-sway bar disposed in the central tube.  Each cartridge has a torque absorption hub with a substantially cylindrical outer surface to match the inner surface of the axle tube.  A plurality of square torsion bars are disposed between each torque absorption hub and the rotating arm. The arm is connected to the wheel.  The torsion bars are disposed in a circular pattern about the central tube.  The torsion bars pass through a bearing assembly connected with each rotating arm. The bearing assembly includes self-lubricating needle bearings. The relative position of the torque absorption hub with respect to the axle tube may be changed to change the road height of the vehicle.  Torsion bars may be added or removed to change load characteristics.  The unique shock absorber system uses a primary shock absorber to absorb relatively small shock forces, and a secondary shock absorber that is mechanically linked to the rotating arm to operate in a progressive fashion.  This mechani-cal linkage includes a secondary arm and two lever arms.  The secondary arm may be repositioned by a unique locking mechanism whenever the road height of the vehicle is changed.  The entire suspension and shock absorber system is mechanically isolated from the vehicular frame and body by resilient rubber blocks to minimize the transmission of shock forces and road noise to the frame and body.

Granted: 1997-02-04
Abstract: The present invention relates to drug carriers composed of a block copolymer having hydrophilic and hydrophobic segments, a polymeric micelle type drug comprising hydrophobic drugs trapped by physical treatments in said drug carrier and methods for trapping hydrophobic drugs in the drug carrier.   The drugs carrier composed of the block copolymer according to the inven-tion forms a stable polymeric micelle structure with which hydrophobic drugs can be incorporated very efficiently via physical trapping.  It was found that the incorporated drug is stably maintained in micelles even in the presence of serum.  In addition, a drug difficult to administer into the living body owing to sparing water-solubility for its high hydrophobicity can be administered in the form of polymeric micelle drug.

Title: Method for the production of a composite structure with an intermediate three-dimensional textile, and a structure made by the method
Inventor: FANTINO MARCO
IPC: B32B37/02
Filed: 1992-05-28
Granted: 2004-02-17
Abstract: A three-dimensional textile (3) formed from two sheets of textile (5, 6) placed face to face and connected together by a plurality of extensible threads (10) is impregnated with resin and inserted between two layers (16, 17) so as to form a layered structure (1). This layered structure (1) is inserted between two dies (25, 26) of a heated press which is subsequently closed to allow the resin impregnating the structure to distribute itself uniformly. The layers (16, 17) are then attached by vacuum to the faces of the dies (25, 26) which are then opened through a first controlled distance within the limit of the elastic recovery of the three-dimensional textile (3). The outermost layers of the structure (1) are then polymerised by heating of the dies (25, 26) while the resin impregnating the threads (10) remains in a plastic state. The lower die (25) is then released in the plane in which it lies and the dies (25, 26) are then moved apart through a second distance so as to stretch the threads of the three-dimensional textile and align them substantially vertically; the floating die (25, 26) is then locked. The dies (25, 26) are then moved away from each other to a predetermined distance to extend the threads (10) completely and the press (28) is kept in this position until all the resin has polymerised completely, the structure hardening in the position assumed.

Title: Lightweight anchor
Inventor: PETERSEN EDWARD RICHARD
IPC: B63B21/44
Filed: 1994-08-10
Granted: 1999-04-27
Abstract: The lightweight or twin-fluke anchor is the most frequently used type of anchor in service on commercial and pleasure boats today. The weakest part of this anchor is the crown assembly. When a force is applied to the shank, the shank bears against the crown plate of the crown assembly at a single point. The embodiment of prior art anchors causes a can-opener like shear stress at the joint between the crown plates and the spacer plates that can cause the anchor to fail. In this invention the problem is eliminated by adding a pair of stop plates to the crown assembly to limit the rotation of the shank. These stop plates engage the shank over a length and greatly strengthen the anchor, eliminating the above type of failure.
