Title: Method of calculating work burden index and apparatus for carrying out the same method and work routine planning method utilizing the same index
Inventor: OGATA SATOSHI
IPC: G01M99/00
Filed: 1994-05-25
Granted: 1999-08-10
Abstract: In order to obtain an index which generally shows the work burden extent of various works carried out in an automobile assembling factory or the like, for each work content, the maximum muscle contraction ratio is measured after the work has been continued for 5 seconds, the work burden index (L) is calculated from the measured ratio value, and the equivalent work burden in a standard work is calculated from the calculated work burden index (L) for 5 seconds. The work burden index (TVAL) of actual work is calculated from the equivalent work burden and the actual work time. Suitably, a work routine plan is corrected such that the obtained TVAL is normalized with an apparatus comprising means for storing the equivalent work burden for each work content, means for displaying an image of the work content, and means for inputting work content parameter and so forth while watching the displayed image.

Granted: 1995-09-26
Abstract: A skinfold caliper (30) for measuring body fat percentages having two opposing clamping surfaces (38, 40) mounted on rigid arms (32, 34) which are connected at their lower end by a resilient member (36). The caliper (30) in-cludes a cantilever arm (46) having a substantially circular projection (48) en-gaging a dimple (50) formed in the caliper (30) when the clamping surfaces (38, 40) exert a predetermined pressure level. This creates an audible and tac-tile signal to the person performing the measurement indicating that the prede-termined pressure level has been reached. A slide (58) on a measuring scale (52) is engaged by one (34) of the arms (34, 36) as the clamping surfaces (38, 40) move toward one another and releases the slide (58) as the clamping sur-faces (38, 40) move away from one another. The pointer (60) on the slide (58) will thus stay at the point on the scale (52) where the clamping surfaces (38, 40) gauged the thickness of the subcutaneous layer of fat of the skinfold (70).

Abstract: A walk-through flat barn parlor comprises a number of modular stalls for managing dairy cows.  Each module has a frame to which a pair of gates are mounted.  The axes of rotation for the gates make compound angles with the vertical such that the gates are biased by gravity to rotate from a closed mode to a ready open mode.  A control mechanism is actuated by a cable mechanism from a milking station to unlock the gates for automatic rotation by gravity from the closed mode to the ready open mode.  A cow walks to the ready open gates and pushes them to the closed mode, where she is constrained for milking.  After completion of milking, the farmer actuates the cable mechanism to unlock the gates and enable the cow to push them to an exit open mode.  When the cow has cleared the gates, they automatically rotate by gravity back toward the closed mode.  A pawl on a bar connecting the gates co-acts with the control means to enable the gates to rotate past the closed mode all the way to the ready open mode.  The cable means includes a reversing mechanism that enables the farmer to actuate the control mechanism in a consistent manner regardless of the side of the stall his milking station is located.

Abstract: A torsion bar assembly for a dishwasher door having a stainless steel torsion bar enclosed in an elongated stainless steel tube such that the bar rotates within the tube as the door is moved between an open and a closed position.  One end of the bar and tube are fixedly disposed in a rectangular boss which is fixedly attached to the dishwasher door; and a second end of the tube and bar are releasably disposed in a cylindrical boss which is welded to a door hinge.  The bosses are attached on opposite sides of the interior door panel, so that the torsion bar extends substantially the width of the door.  The torsion bar is protected from water by the corrosion-resistant tube, and by a pair of quad-rings which are disposed in recesses in the cylindrical boss.  The quad-rings prevent water from seeping through the boss and reaching the torsion bar.  When the ends of the torsion bar are disposed in the bosses, the bar is spaced within the tube to permit the bar to rotate independently of the tube.  This rotation builds up torque in the torsion bar.  This torque is released when the door is closed, to supplement the effort needed to close the door.

Title: Method for selecting ama records using individual directory numbers
Inventor: SCHNABLE ANDREW THOMAS
IPC: H04M15/00
Filed: 1996-03-11
Granted: 1999-12-28
Abstract: In an automatic message accounting (AMA) record distribution network, a method and system for sorting AMA records by using an area code or numbering plan area (NPA) data array and directory number bit maps to identify AMA records which are of interest to an operation center. Operation centers have access to every AMA record generated by a toll switching network and are initialized with a table of AMA structure and call-type codes, an NPA data array and directory number bit maps. NPA entries in the data array which are of interest to a particular operation center contain pointers (i.e., memory address locations) of the directory number bit maps. As AMA records are received by the operation center, directory numbers which have NPAs of interest to the operation center are compared to directory number bit maps. A directory number of an AMA record which corresponds to a numbered bit position of the directory number bit map is processed by the operation center. AMA records which contain directory numbers which do not have NPAs of interest to the operation center, or which do not correspond to a directory number bit map are discarded.
