An apparatus for varying nip pressure in a media feedpath including a feed roller and a pressure roller defining a feed nip there between includes a rotatable cam having a preselected eccentric path when rotated, a first pivotable linkage pivotally engaging the rotatable cam, a second pivotable linkage, a biasing member operably interconnecting the first and second pivotal linkages for providing a biasing force on the pressure roller. The pressure roller is rotatably connected to the second linkage opposite the biasing member, wherein rotation of the cam varies the biasing force provided by the biasing member on the pressure roller.

A regulating device includes a regulating valve with a valve housing, which has a fluid inlet, a fluid outlet, accomodates the valve elements pressing by the fluid pressure in the fluid inlet, biasing element, and is compressed between the valve element and plug, and resists the bias force of the fluid pressure to the valve element. With the development of the fluid pressure, the valve element moves owing to resisting bias force so as to communicate fluid inlet and fluid outlet. The valve element makes the plug move outward relative to the valve housing by bias element so as to reduce the bias force, when the fluid pressure is equal to or more than the preset pressure. A displacement regulation unit coming against plug is to limit its movement and regulate the reduction of the bias force.

Combined computer and communications apparatus is described which has an improved hinging arrangement between two casing halves (1, 2). By enabling each casing half to hinge around one of two spaced parallel hinge axes, with a hinge including an articulated linkage (28, 30) having its ends pivoted around the two hinge axes, improved snap action open or closed may be achieved. The articulated linkage has two pivots (21) intermediate its ends, each pivoted to one of the casing halves (1, 2). Spring means (20) urge the casing halves together or into a coplanar arrangement.

The invention provides a slip sheet of a vane type compressor and the vane type compressor. The slip sheet comprises a first side face (71) and a second side face (72), wherein the first side face (71) and the second side face (72) are arranged back to back; a side face oil groove (73) for accommodating high pressure oil is formed in the second side face (72); and the side face oil groove (73) is formed in the direction towards the first side face (71) from the second side face (72) and does not penetrate through the first side face (71). According to the invention, high pressure oil can be fed in through the side face oil groove, so that pressure perpendicular to the slip sheet is formed on the second side face of the slip sheet to balance or reduce biasing force, moment of force is enabled to reach balance as much as possible, the slip sheet is prevented from abnormal abrasion generated by line contact formed between the slip sheet and a slip sheet notch due to the biasing force, surface contact is formed, the service life of the slip sheet is prolonged to certain degree, and the frictional power consumption at the part is reduced, wherein the biasing force is generated when the front end of the slip sheet is subjected to pressure of a high-pressure cavity and a lower-pressure cavity on two sides.

An application roller arm assembly for use with a tape cartridge includes a support arm having first and second ends and adapted to be coupled to the tape cartridge. The application roller arm assembly also includes a coupling for a biasing element. The coupling is coupled to the support arm and the biasing element is configured to be coupled to the coupling and the tape cartridge. Further, the application roller arm assembly includes a mechanism for reducing a biasing force from the biasing element. The mechanism is configured to be coupled the support arm and the tape cartridge.

An expansion valve for a refrigerant cycle has an orifice passage portion, a valve body, a spring member and a deformation portion. The orifice passage portion is configured for decompressing and expanding a high pressure refrigerant into a low pressure refrigerant. The valve body is disposed to open and close the orifice passage portion so that a flow rate of the low pressure refrigerant flowing into a low pressure passage portion is controlled in accordance with a valve opening degree. The spring member is disposed between the valve body and the deformation portion for applying a biasing force to the valve body. The deformation portion is plastically deformable in a direction parallel to an expansion and contraction direction of the spring member by applying an external force.

A hinge structure for interconnecting the temples of glasses or spectacles to the frame thereof is disclosed. The hinge structure is made of resilient polymeric material such as elastomeric material. The hinge structure also defines a generally smooth inner surface and a generally corrugated or bellows-shaped outer surface. The elastically compressible alternating ridges and furrows of the corrugation bias the temples of the glasses toward each other, thereby securing the temples to the head of the wearer. Still, at least one of the furrows is further provided with an enlarged groove at the bottom thereof to reduce the tension of the temples on the head of the wearer.

An output part is provided to the left end of a clamp arm that is supported by a housing so as to be slidable in the vertical direction. At the left end of the housing, a first hole for spring fitting opens obliquely upward towards the output part. A through hole that links the upper surface and the lower surface of the clamp arm is disposed obliquely upward at a left-leaning part of the clamp arm. A second hole for spring fitting and a female screw hole are formed, in that order, upwards in the through hole. A return spring that is installed through the first hole and the second hole impels the output part upwards. A push bolt that is screwed into the female screw hole rom above compresses the return spring.
