IPC: B66C13/23
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To enable positioning for a fixed distance regardless of variation in ON-time of an operation command and surely execute the stop of movement according to OFF of the operation command by operating only during a preset prescribed time regardless of length of ON-time of an operation command input. SOLUTION: When an operation command is input by open/close operation of a normal rotation command contact Fa1 or a reverse rotation command contact Fa2, an inverter control circuit 2 starts speed control by the rise of an operation command. Subsequently, when the operation command contact Fa1 or Fa2 is operated from ON to OFF, the control circuit 2 stops the operation. That is, the control operation is conducted during ON state of the operation command contact Fa1 or Fa2. The control circuit 2 judges whether predetermined time passes or not on detecting the rise of the next operation command, and if not, the operation command is disregarded to continue stopping, and if yes, again the speed control is conducted.

Title: Corrosion-resistance judging method for zirconium group alloy
Inventor: OGATA KEIZO
IPC: G21C17/06
Filed: 1988-06-14
Abstract: PURPOSE:To eliminate the effect of an oxide film which is formed during the increase in temperature of a test piece and to make it possible to judge sensitivity for nodular corrosion by loading the test piece into a pressure container in which steam atmosphere of 50-150kg/cm<2> is maintained. CONSTITUTION:A test piece is loaded into a pressure container in which a steam atmosphere of 50-150kg/cm<2> is maintained. The temperature of the test piece is increased to 530-550 deg.C at a temperature increasing speed of 2 deg.C/min. The temperature of the test piece is maintained for 1-60 minutes (this is referred to first-stage heating). Then the temperature is decreased down to 450-510 deg.C. This temperature is maintained for 4-24 hours (this is referred to second-stage heating). The corrosion resistance of the test piece under this condition is judged from the increase in weight of the test piece. An oxide film, which gives effect on corrosion of the test piece in steam, is formed during temperature increase, but the effect is eliminated in this way. Sensitivity for nodular corrosion can be judged sensitively and stably.

Title: Character reading system
Inventor: TOMONO KOZO
IPC: G06K9/62
Filed: 1988-06-13
Abstract: PURPOSE:To read a character by good precision by dividing an input character pattern and a reference character pattern into plural parts respectively and calculating similarity by obtaining the optimum coordination between partial patterns according to the value of partial similarity between the divided partial patterns. CONSTITUTION:A recognizing means 4 calculates the optimum partial similarity between the partial patterns of the input character pattern and the reference character pattern according to a partial similarity table 6. Then, the recognizing means 4 selects combination in which the sum of those partial similarities becomes maximum, and obtains the similarity between the input character pattern and the reference character pattern according to this combination. Accordingly, even though the dislocation exists in the superposition of the input character pattern and the reference character pattern, this dislocation becomes minimum. Thus, even when a part of the input character pattern is lacked or the shape of the pattern becomes large because of a noise, the character can be read by good precision.
