Title: Controlling method for injection molding machine and equipment
Inventor: YUMIKAKE MASARU
IPC: B29C45/76
Filed: 1990-05-18
Abstract: PURPOSE:To prevent waste of a molded form by starting automatic operation and thereafter detecting a time interval wherein the magnitude of physical quantity obtained at every molding cycle is continuously present within a monitoring range and starting an automatic discrimination function when this detected value exceeds the preset time internal. CONSTITUTION:Automaic operation of an injection molding machine 1 is started. The magnitude of physical quantity which is obtained in the initial molding cycle is comparted with the preset monitoring range and a normal/defective condition discriminating signal S is output. In this case, the cycle counter part 13 of a second abnormal command part 12 performs one count. Further when the said signals S for a plurality of physical quantities are all normal condition discriminating signals Sy, a nondefective counter part 4 in a first detection part 2 performs one count and a defective counter part 9 in a second detection part 7 is rest to zero. On the other and, even when only one of defective condition discriminating signal Sn is present among the signals S, the defective counter part 9 performs one count and the nondefective counter part 4 is reset to zero. When the count value of the nondefective count part 4 reaches the set value preceding the other count value, an automatic discrimination function is started by a start-up command signal output from a comparison part 6.

Title: Heart pacemaker device
Inventor: KAWAKAMI TAKASHI
IPC: A61N1/37
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To enhance safety noticeably by a method wherein a spacing signal is outputted to an atrium cordis or a ventricle or both thereof according to detection when a coefficient means count a coefficient value exceeding a specified value to secure a pacing of a fixed heart rate on the side of a heart pacemaker. SOLUTION: When a plenty of interfering noises exist, during the period of detecting second electrocardiographic inputs, noises mistaken for electrocardiographic input signals as represented by S1 , S2 ... and Sn beyond a threshold are detected surpassing a specified frequency despite the fact that no cardiac input signal is generated based on a physiologic constrictive motion. This blocks the intrinsic action which outputs a pacing signal a ventricle to electrically stimulates the ventricle thereby causing a danger of obstructing the circulation of blood. To avoid the checking of the outputting of this bacing signal, a control is performed to output the pacing signal at each moment of detection without waiting for the ending of a predetermined sensing period when a coefficient value of a signal surpassing the threshold reaches a specified value N.
