Abstract: Abstract of the Disclosure Immediate stabilization and subsequent promotion of bone-to-bone fusion is achieved in a joint where separation of the bones is restricted by surrounding ligaments or other soft tissue. A hole is bored transversely across the joint. A slightly larger cylindrical basket is driven into the hole, thereby spreading the bones in resistance to the tensile forces of the surrounding tissue. Immediate stabilization of the joint is achieved by the implantation of the rigid cylindrical basket. Subsequent bone-to-bone fusion is achieved, both through and about the basket, which is filled with bone fragments produced during the boring step.

Abstract: Abstract:        A brake control device for preventing backward movement of a vehicle on an uphill road during operation of the clutch pedal after release of the brake pedal, the device including a cylinder body having iol passages for connection between the master cylinder and the wheel cylinders of the vehicle.  A spring biased hollow plunger is reciprocably received within the cylinder body to provide flow communication between the oil passages in a first position thereof when the brake pedal is actuated, and to prevent the oil from returning from the wheel cylinders in a second position thereof when the clutch pedal is actuated upon release of the brake pedal.  An electromagnetic switch-activated system moves the hollow plunger from the first position to the second position when the clutch pedal is actuated.  A second oil path is provided in the cylinder body to supply additional oil from the master cylinder to the wheel cylinders when the hollow plunger is in the second position and the brake pedal is reactuated for  an increased braking force.

Abstract: ABSTRACT OF DISCLOSURE  Optical Memory System Having Improved Track Following and Seeking Capabilities A high density optical data storage system employing a laser beam for reading data in a track on a rotating optical disk containing a large number of closely spaced concentric tracks.  The system provides for track following as well as long and short seek track moving operations.  Track following and short seeking operations share the use of a galvanometer-controlled mirror in the path of the beam, while long seek operations are performed using a positioning motor which is also used during track following to reduce the deflection required to be provided by the galvanometer mirror.  The short seek operation uses a specially shaped doublet waveform comprised of opposite polarity pulses chosen based on the number of tracks to be moved and the mechanical characteristics of the system.

Abstract: A CONTROL DEVICE AND METHOD FOR                ACTIVATING A FUEL INJECTOR NOZZLE                       Abstract of the Disclosure A control device and method for opening and closing the nozzle of a fuel injector rapidly and precisely to provide a sharp cut off of injection so as to achieve better combustion, less smoke and lower emissions.  The control device includes first and second cavities formed in the body of the fuel injector, with the second cavity being located close to the nozzle.  First and second variable pressure supply chambers are connected to the nozzle and to the cavities by several fluid passages.  A spool valve and a needle valve are positioned in the first and second cavities, respectively, with the spool valve having a stem projecting into the second cavity.  A spring is situated in the second cavity and forms a link between the stem and the needle valve.  The spool valve is actuated by a difference of pressure in the first and second pressure chambers to move between open and closed positions.  In the open position, fluid flow from one of the pressure chambers is permitted through the spool valve and to the second cavity.  As the fluid pressure in the second cavity increases sufficiently to overcome the force of the spring, the needle valve opens and allows fluid flow through the nozzle.  As the spool valve moves to its closed position, it compresses the spring further and urges the needle valve to close.  The needle valve closes prior to a drop in fluid pressure in the second cavity.

Abstract: GEAR ARRANGEMEMT FOR A MOTOR VEHICLE      Abstract of the Disclosure An engine shaft drives oppositely rotating bevel gears which can be coupled to a hollow clutch shaft by forward and reverse clutches.  The clutch shaft is coupled to the input shaft of a six-speed, change-speed gearbox through a two-stage epicyclic range gear with a direct drive clutch and brakes for engaging the overdrive and underdrive stages, respectively. An epicyclic creep gear can be selectively switched in upstream of the range gear.  Thus, a coupling sleeve couples the clutch shaft either to the input of the range gear or to the input sun wheel of the creep gear.  Since the creep gear reverses the sense of rotation, a changeover of control of the clutches is effected when the creep gear is engaged.

Title: Apparatus for the electrodeposition of electrically  insulating coatings
Inventor: NISHIMURA TSUGIO
IPC: C25D15/00

Granted: 1986-08-19
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for the electrodeposition of electrically insulating coatings according to the present invention comprises means for causing an electrodeposition paint containing mica to flow extremely slowly from the top to the bottom of an electrodeposition tank past an object to be coated by electrodepostion.  Compared with electrodeposition apparatuses which employ horizontal flow of electrodeposition paint from one side of a tank to the other, the flow speed is lower and there is no tendency for electrodeposition to occur faster on thoses surfaces of the object which face upstream in the flow than on those surfaces which face downstream. A highly uniform insulating coating having a high mica content can be produced using this electrodeposition apparatus.

Abstract: INK LEVEL CONTROL FOR INK JET PRINTER            Abstract of the Disclosure The level of ink in a reciprocating reservoir is automatically controlled for both printing and non-printing conditions.  The reciprorating motion creates forces to cause the ink to move back and forth between the reciprocating reservoir and a main reservoir and a pump maintains the ink at one level during printing. The pump controls the direction and flow of ink moving between the reservoirs by continuous operation during printing and the ink is allowed to rise in the first-mentioned reservoir during non-printing.

Abstract: Starting Enrichment Of Alternate Firing Two Cycle Internal Combustion Engine Abstract A two cycle internal combustion engine (10) has at least two cylinders (12, 13) which fire alternately with pressure in one crankcase (17 or 18) at the time there is vacuum in the other. Supplemental fuel flow passages (36, 41) extend from each crankcase and are joined at a common passage (46) connected to the float bowl (30) of the carburetor (20).  A normally closed control valve (48) is disposed in the common passage.  When the engine is to be started, the control valve is opened so that fuel enters the supplemental and common passage.  Initial rotation of the crank-shaft (16) causes pressure in one crankcase to force fuel toward the other crankcase, which has vacuum.  Further crankshaft rotation reverses the pressures so that fuel is then forced toward the opposite crankcase.  Continued engine operation with the control valve open causes alternate fuel flow reversals together with pressurized alternate fuel injections into the respective crank-cases, which are independent of the throttle setting.
