IPC: G06Q50/28
Filed: 1992-06-22
Abstract: PURPOSE:To provide an automatic correcting device for the shipment schedule data which can improve its working efficiency even to such a product that is possible to cause small amount of stockout or the excessive stock, by changing the ordering points and the production lots of the product to each optimum value. CONSTITUTION:A data comparing part 1 compares the expected shipment value with the actual shipment result value of the precedent month and at the same time decides whether the stockout occurred or not in the precedent month. If the actual shipment result value is larger than the expected shipment value and also if it is judged that the stockout has occurred, an ordering point correction processing part 4 corrects the ordering point stock value of the present month of the shipment schedule data based on the necessary change value calculated by an ordering point change value calculation part 2. Meanwhile, a production lot correction processing part 5 corrects the production lot value of the present month of the shipment schedule data based on the necessary change value calculated by a production lot change value calculation part 3 if the expected shipment value is larger than the value obtained by multiplying the actual shipment result value by a fixed coefficient and also the absence of stock is not confirmed.

Title: Non-contact full circumference type potentiometer
Inventor: NAKANO EIJI
IPC: G01D5/18
Filed: 1985-07-24
Abstract: PURPOSE:To enable the detection of the angle of rotation over the entire circum ference with a magnetic reluctance element sensor for detecting linear move ment, by determining in what angle of rotation area an input shaft exists. CONSTITUTION:A magnetic ring 3 is provided on the surface of a disk 2 fixed on an input shaft 1 as concave ridge in a closed loop. This ring 3 is built as yoke facing a magnet 4 through a magnetic reluctance element sensor 5 for detecting linear movement and it is so arranged that the distance to the ring 3 from the center thereof increases or decreases in proportion to the angle of rotation of the disk 2 while the position of hte ring 3 makes a reciprocation radially while the disk 2 turns at one cycle, eventually making the ring 3 a heart in the shape. The sensor 5 is so arrayed that a pair of magnetic elements are turned to the radial direction of the disk 2 in orientation to enable the detection of the position in the radial direction of the ring 3. This facilitates the decision on the angle area where the input shaft exists. The detection can be done simply by discriminating only two locations, right or left and the angle of rotation of the input shaft 1 also can be detemined from the output of the sensor 5.

Filed: 1987-06-30
Abstract: PURPOSE:To reduce dark and noise currents by monolithically forming acceleration resistance for generating voltage for accelerating secondary electrons generated inside a secondary electron multiplying tube toward a collector, in a part of the tube. CONSTITUTION:A current flowing in a secondary electron multifying tube 2 with application of high voltage and a resistor constituent held by a portion ranging from an anode 4 of the tube 2 to an insertion end 21a of a collector 21 causes voltage to decrease to form acceleration voltage of secondary electrons to the collector 21.
