Abstract: A reciprocatory piston type compressor is provided with partition walls in a discharge chamber or chambers, the walls being arranged between discharge ports open to the discharge chamber, respectively, to prevent flows of refrigerant gas discharged from the discharge ports from directly interfering with each other at least during the time in which the opening of two adjacent discharge reed valves overlap one another. The partition walls may be formed integrally with a cylinder head of the compressor in such a manner that the partition walls extend centripetally from an inner wall surface of the cylinder head defining the discharge chamber. The flows of refrigerant gas discharged from the two adjacent discharge ports which are open will not interfere with each other but will be guided independently and centripetally along the partition walls in the discharge chamber toward the tops of the partition walls, and then toward an opening that leads to an outer discharge conduit.

Abstract: A porous filter element for filtering a liquid, the filter element having a plurality of seamless filter element units that are made of stainless steel or titanium powder wherein ranges of particle diameters, sintering densities, and nominal pore sizes define a final shape which is formed with undulations to provide bed surfaces for an auxiliary filtering agent.

Abstract: A construction of a mudguard of a movable fender portion in a motor vehicle.The motor vehicle is provided therein with a side door hinge mechanism utilizing a quadric crank chain comprising: a front rotary link interconnecting two points which are disposed at the front side of a vehicle body and a side door in the motor vehicle as rotary shafts out of four points including two points disposed on the vehicle body and spaced apart from each other in the longitudinal direction of the vehicle body and two points disposed on the side door and spaced apart from each other in the longitudinal direction of the side door; a rear rotary link interconnecting two points disposed at the rear sides as rotary shafts; a portion between the two points on the vehicle body; and a portion between the two points on the side door.

Abstract: A hinge mechanism for a vehicle door including a support arm and a control arm, both which are pivotably connected between a mounting surface along the vehicle body and the door. The support arm is typically mounted forward of the control arm along the vehicle body. The door includes an end surface extending between an exterior and an interior of the door adjacent the mounting surface of the vehicle body. The end surface has a lower vertical section measuring a predetermined length and an upper inclined section. The mounting surface is aligned with the vertical section. The support arm extends along a substantial portion of the predetermined length of the vertical section of the door. The support arm is mounted to the mounting surface of the vehicle body by a first shaft and a second shaft pivotally mounts the door along the end surface thereof to the opposite end of the support arm.

Abstract: A hinge mechanism for a vehicle door, in which a vehicle body includes a door section having an arm rest extending along an interior portion thereof. The bottom surface of the arm rest contains a recessed section defined along the vehicle interior by a contour line extending along at least a forward portion of the bottom surface of the arm rest. A support arm extends between the door section and the vehicle body to provide primary support for the door section. A control arm with attached cover extends between the door section and the vehicle body for guiding the door section when the door section is opened and closed. The support arm and the control arm are pivotally attached to both the door section and the vehicle body. The control arm and cover have a cross-sectional dimension, when viewed from above, substantially corresponding to the contour line, enabling the control arm and cover to be substantially flush with the contour line when the door is closed.
