Title: Investigation distance setting method for industrial robot
Inventor: KANAMORI JUNICHIRO
IPC: G05B19/42
Filed: 1994-09-28
Abstract: PURPOSE: To properly set investigation distance between the work center point and an investigation point without increasing the work failure frequency. CONSTITUTION: The variance distribution is measured for the relative position between hole and ramp of a base board before the work is started. Distribution function of the work success rate is calculated based on the measured dispersion distribution and an allowable work success error. When the success rate is measured at the work center point, the position of this success rate is estimated in the work success rate distribution. Then, the distance from a point where the work success rate is maximized is set as an investigation distance. If the work fails and the work center point is corrected, the investigation distance is set again based on the success rate calculated at a new work center point.  As the investigation point is variable, the correcting point quickly comes near to the highest success rate point when the correcting point is set distant away from the highest success point. Meanwhile, the correcting point can surely get closer to the highest success rate point without passing over this point when the correcting point is set close to the highest success point.

Title: Deoxidizing multilayer body of paper base material and paper container
Inventor: OTAKI RYOJI
IPC: B65D81/26
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To shut off a penetrating oxygen from outside a container and enable oxygen in the space of the container and a dissolved oxygen in an article to be removed by laminating a paper base material layer, a gas barrier layer, an oxygen absorbing resin layer consisting of a deoxidizing agent dispersed in a thermoplastic resin and an oxygen-permeable resin layer laminated in that order from the outer face side. SOLUTION: A paper base material layer, a gas barrier layer, an oxygen absorbing resin layer consisting of a deoxidizing agent dispersed in a thermoplastic resin and an oxygen- permeable resin layer are laminated in that order to form a deoxidizing multilayer body of a paper base material. In addition, the container is formed in such a manner that the oxygen-permeable resin layer becomes the inside of the container, using steps to process the end face, bond a barrel part and form a bottom part and a top part, e.g. a hemming process or the like that the bonded part of the barrel part is folded to the outside so as to keep the end face of the deoxidizing multilayer body from coming into contact with the content.  The container is used as a packaging material for foods, medical supplies or the like, and the residual oxygen contained in the space part of the container or its stored article permeates through the oxygen-permeable resin layer and is absorbed by the deoxidizing agent in the thermoplastic resin. On the other hand, oxygen outside the container is shut off by the gas barrier layer to keep a low oxygen concentration level internally for a long time and thereby the qualitative deterioration of the article is prevented from occurring.

IPC: G11C11/34
Filed: 1987-09-18
Abstract: PURPOSE:To accelerate operating speed and to reduce power consumption by supplying a voltage which applies reverse bias on a MOS FET for switching to a word line not being selected. CONSTITUTION:An nMOS FET6 for clamping is set at an ON state when no word line 2 is selected, and a voltage held in a capacitor, for example, the voltage of -5V is supplied to the gate electrode of an nMOS FET8 for switching from the word line 2, which sets the nMOS FET8 at an OFF state. Thus, since the voltage which applies the reverse bias on the inverse of nMOS FET8 is supplied, it is possible to form the nMOS FET8 by the MOS FET with a low threshold voltage, and to form the MOS FET in a peripheral circuit by the MOS FET with the low threshold voltage. In such a way, the acceleration of the operation speed and the reduction of the power consumption can be realized.
