摘要:
A combinatorial weighing method and apparatus in which weight data from N-number of weighing machines containing articles are combined to obtain an optimum combination of weighing machines giving a total combined weight value of articles equal to a preset value Wa or closet to the preset value Wa within preset allowable limits, and in which the articles are discharged from the obtained optimum combination of weighing machines. The method includes starting combinations with i as the initial number of weighing machines in each combination, wherein i represents the number of weighing machines which tends to afford the optimum combination more readily than other numbers of the weighing machines. Combinations which select the i-number of weighing machines from the N-number of weighing machines, are generated continuously and it is determined whether the total weight value of each combination machine falls within the preset allowable limits. A combination which is within the preset allowable limits is stored, and articles are discharged based on the stored optimum combination. The initial value of i is set to N/2 when N is even, to (N/2).+-.0.5 when N is odd, or to a value obtained by performing the following operation: ##EQU1## where Wi (i=1, 2, . . . , N) represents the weight of article batches supplied to each of the weighing machines. For each total weight value of a certain combination that is obtained, the value is ranked as being underweight, proper or overweight, the weight values are counted rank by rank, and the quantity of articles suppled to the weighing hoppers is controlled based on the counted value in each rank. When an optimum combination is not found with the initial number of weighing machines, i is updated based on the counted value in each rank, and processing for selection of an optimum combination is re-executed.

An ultrasonic measuring apparatus of the type having a pair of transducers disposed oppositely on a pipe through which a fluid to be measured flows and which are so controlled alternately as to convert an input electrical signal to an acoustic signal and to convert a received acoustic signal to a received electrical signal. The apparatus includes a time difference detecting means for receiving an output signal from a delay means and the received electrical signal for detecting a time difference between a delayed counting time obtained from the delay means and a propagating time required for an ultrasonic wave to propagate through the fluid to be measured. Comparing means are provided for comparing a voltage signal corresponding to the time difference with first and second set voltages and monitoring means receiving the comparison result from the comparing means for judging whether the fluid flow is propagated in the pipe in a normal condition or in an abnormal condition. The present invention ensures a quick detection of abnormal propagation of the ultrasonic wave in the pipe and obtains a correct measurement values without misjudgement.

A puffer type gas circuit breaker comprises a first and a second arcing electrodes movable relative to each other, an insulating nozzle surrounding the second arcing electrode, a puffer device for introducing an arc-suppressing gas into the insulating nozzle to puff out the arc produced between the two arcing electrodes when the breaker is in motion for circuit breaking, and a movable shield device for relieving the concentration of an electric field at the front end of the first arcing electrode during the breaker motion for circuit breaking. When the breaker is closed and the circuit made, the movable shield device surrounds the first arcing electrode and insulating nozzle, with a predetermined gap between itself and the insulating nozzle opposite thereto, and is kept at the same potential as the first arcing electrode. The circuit breaker further includes a device for maintaining the predetermined gap and the same potential at least in the early stage of the breaker motion for current breaking.

In a vehicle pop-up hood apparatus in which a rod is extended and a hood is pushed up by the operation of an actuator at a time of collision with a collision body, collision energy is absorbed with high efficiency when a collision load of a predetermined value or greater is input to an area near a hood pushed up position.Actuator (18) operates such that rod (20) moves in an axial direction toward a hood upper side, pushes up a rear edge side of hood rocker (12) and holds it at that position and, in that state, when a collision load of a predetermined value or greater acts from a hood upper side to near the pushed up position of the hood, push portion (54) slides along pushed up surface (38) of hinge arm (30) towards a vehicle rear side, and rod (20) is made to bend in conjunction therewith.

A measuring device is arranged to store a block or group of a plurality of objects in a state where the objects are congested in the block, to suppress the scattering magnification of the objects when the objects are dropped off to prevent failures such as seal bite in a filling device disposed below the measuring device, to shorten the dropping length of the objects, and to reduce the contact resistance of the objects to a receiving opening of the filling device during the objects are dropped off to attain the discharging speed of the objects. The shapes and opening degrees of a gate unit can be changed so that a lower opening of a hopper is disposed inside the receiving opening of the filling device in a top plan view.

A production system is provided in which high production efficiency can be maintained in the entire production line even in cases in which there is a lack of uniformity in the rates at which the articles are actually supplied from a supply unit; the weighing unit, packaging unit, quality inspection unit, or other constituent device has stopped operating; or other problems have occurred. In this production system, a centralized control system controls the set capacities of devices that constitute a production line including a weighing device, a bagging machine, and other devices disposed downstream, so that the capacities are varied on the basis of the detection results of a supply rate detection sensor of a supply device, that is, on the basis of the actual rates of supply from the supply device to the weighing device.
