Title: Truck cover having an improved telescopic arm assembly
Inventor: GOLDSTEIN HARVEY R
IPC: B60P7/04
Filed: 1987-12-03
Granted: 1992-05-26
Abstract: ABSTRACT        A truck cover having an improved telescopic arm assembly for drawing a cover across an open topped truck body or other vessel  or  container.   The  assembly  comprises  a  pair  of telescopic  arms  and  motive  means  powered  by  a  pneumatic, hydraulic or other power source.   The motive means cause the telescopic arms to move pivotally from one end of the container to the opposite end and during the pivotal movement to cause the  telescopic  arms  to  retract  as  they move  to  a vertical position and to extend as they move from the vertical position to  the  opposite  end  of  the  container.   The  extension  and retraction of the telescopic arms during pivotal movement from one end of the container to the opposite end causes a flexible cover carried by the upper ends of the telescopic arms to be drawn  across  the  container in a low trajectory resulting in improved ease and safety of operation and reduced opportunity for damage to the flexible cover.

Title: Variable displacement compressor with biased inclined  member
Inventor: TERAUCHI KIYOSHI
IPC: F04B1/28
Filed: 1988-05-18
Granted: 1993-11-16
Abstract: ABSTRACT OF THE DISCLOSURE       A reciprocating piston type refrigerant compressor is dis-closed. The compressor includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber adjacent the cylinder block. A piston slides within each cylinder and is recip-rocated by a drive mechanism which includes a rotary drive shaft, a rotor mounted on the drive shaft, and a coupling mechanism which converts the rotary motion of the rotor into the reciprocating motion of the pistons. The coupling mechanism includes an inclined member which has an inclined surface disposed at an adjustable incline angle. Accordingly, the stroke of the pistons within the cylinders can be changed by adjusting the incline angle of the inclined surface in response to the change of pressure in the crank chamber. A spring applies a force to urge the inclined surface to a decreased incline angle when the incline angle is greater than a predetermined incline angle, but applies no force when the angle is less incline than the predetermined incline angle.

Title: Subscriber line interface circuit
Inventor: TANIMOTO HIROSHI
IPC: H04Q3/42
Filed: 1988-08-18
Granted: 1991-11-26
Abstract: Abstract of the Disclosure The subscriber line interface circuit comprises subscriber nodes, reception nodes and transmission nodes, a power feeding unit, adders, impedance elements, an inverting amplifier, and a feedback element.  The subscriber nodes are coupled to a subscriber terminal via a subscriber line, and the reception and transmission nodes are coupled to an exchange via a reception line and a transmission line, respectively.          The feeding unit supplies a DC current to the terminal and controls the current.  The first adder adds the voltage between the subscriber nodes and the voltage from the reception node.  The first impedance element has an impedance corresponding to a real-number multiplication of the impedance between the subscriber nodes, and is applied with the output voltage of the first adder.  The amplifier is given with the output of the first impedance element.  The second impedance ele-ment, inserted in the feedback path of the amplifier, has an impedance corresponding to a real-number multiplication of the impedances of the subscriber line and the terminal.  The feedback element supplies, to the feeding unit, a signal corresponding to the current flowing through the first impedance element as a control signal.  The second adder adds the output voltage of the amplifier, the output voltage of the first adder and the voltage of the reception nodes, and supplies the resultant signal to the transmission nodes.

Abstract: Abstract of the Disclosure Disclosed is a device for reshaping the contour surface of the plastic injection hole of a metal mold. It essentially comprises a magnetic block and a cutter tool. The magnetic block is capable of switching from magnetizing to demagnetizing position and vice versa. The magnetic block can be attached to the metal mold when it is switched to magnetizing position. The magnetic block is put in demagnetizing positiion, and the magnetic block is moved on the metal mold until it is put in alignment with the center of the plastic injection hole of the metal mold. The cutter tool is attached to the magnetic block by switching to magnetizing position, and then the cutter tool is automatically put in alignment with the center of the injection hole. The worn injection hole can be reshaped to its original shape simply by rotating the cutter tool by hand. Thus, necessary reshaping work can be performed in situ without removing a heavy mold and setting it in a lathe.
