IPC: G06T7/00
Filed: 1988-08-05
Abstract: PURPOSE:To decide the difference of the pattern width data strings of a reference pattern and a pattern to be inspected as not a pattern defect when it is within a prescribed value by converting two-dimensional pattern data to the pattern width data string, comparing the pattern width data strings of the reference pattern and the pattern to be inspected, and deciding a comparison result by permitting micro difference.

Also, a reference pattern width data string stored in a pattern width data memory 8 is inputted to the decision part 6. The decision part 6 decides that a defect exists in the pattern of work to be inspected by comparing the pattern width data string of the pattern to be inspected with a reference pattern width data string group, and when recognizing that no reference pattern width data string within an allowable value exists in the pattern width data string of the work to be inspected and the number of such data strings exceeding a constant number continues. In such a way, the pattern permitted within a constant range is not decided as a defective pattern.

IPC: B23P19/06
Filed: 1992-07-22
Abstract: PURPOSE:To increase the operation rate of a screw tightening device and shorten the cycle time. CONSTITUTION:The detection of the outside torque is started 238, 240, at the time when the torque in the main tightening becomes over Tq-Tt (Tq: final aimed torque, Tt: allowable range). When the outside torque is less than a limit value and the final torque is within an allowable range 242, 246, 'OK' is judged.

Title: Excess current protecting device for photoelectric switch
Inventor: HIROSE TAKUMI
IPC: H03K17/08
Filed: 1986-08-21
Abstract: PURPOSE:To reduce load on an output switching element by discriminating a charging current from the excess current due to the load, by the delay time of a timer to suppress a time for re-energizing as shorter as possible at time of an excess current. CONSTITUTION:It is possible to discriminate a current which flows on the load through a transistor 6 at time of overload whether it is the excess current due to a short-circuit accident, or the charging current due to capacitive load, by the delay time of the timer, thereby, the turnning off of the transistor 6 is not generated at time of charging. Also, at time of the excess current, after the transistor 6 is turned off in the lapse of the delay time of the timer 10, and when the count value of a counter 15 which counts a projecting pulse P3b, goes to a prescribed value, the transistor 6 is turned on based on the output of the counter signal S13 of the counter 15, and the transistor 6 is turned off based on an interruption signal S13 from the flip-flop 13 of an excess current decision circuit 14. Therefore, only a difference between the pulse widths of a detecting pulse P3 a and the projecting pulse P3 b is used as the re-energizing time of the load by the transistor 6, and it is possible to suppress the excess current from being permitted to flow on the transistor 6 at the minimum amount.

Title: Purification of 2,2,2-trifluoroethanol
Inventor: NAKAMURA AKIHIRO
IPC: C07C31/38
Filed: 1985-09-06
Abstract: PURPOSE:To purify 2,2,2-trifluoroethanol containing an S component as an impurity, by adding large excess H2O2 to the crude 2,2,2-trifluoroethanol, heating the mixture under refluxing, decomposing residual hydrogen peroxide, adding an alkali to the product to convert the S component to non-volatile material and distilling the reaction product. CONSTITUTION:Crude 2,2,2-trifluoroethanol containing a sulfur compound component as an impurity is heated under refluxing in the presence of large excess hydrogen peroxide based on the sulfur compound, residual hydrogen peroxide is decomposed, an alkali (preferably sodium hydroxide) is added to the product to convert the sulfur component to non-volatile material, and the reaction mixture is distilled to obtain purified 2,2,2-trifluoroethanol. To prevent the residue of hydrogen peroxide and its explosion hazard, it is preferable to add a reducing substance (e.g. sodium bisulfite) to the system after the heat refluxing and prior to the addition of the alkali, thereby decomposing the residual hydrogen peroxide. A high-quality colorless product free from sulfur odor can be produced by this process.

Title: Rubber reinforcing polyester fiber
Inventor: HIRANO MIYUKI
IPC: D06M101/30
Filed: 1987-08-05
Abstract: PURPOSE: To inhibit the degradation of polyester fibers in curing rubber and also to improve its heat resistance in rubber by imparting and/or including a specific chelating agent to polyester fibers. CONSTITUTION: This polyester fiber for reinforcing rubber is prepared by imparting and/or including 0.1-50 wt.% chelating agent (e.g. one kind selected from benzoin, hydroxyquinoline, ethylenediaminetetraacetic acid or the like) to polyester fiber before burying it as a reinforcer in rubber (e.g. in a spinning operation, a drawing one or the like). The fiber is effective as a rubber- reinforcing material in tires, belts or the like because its degradation is remarkably decreased in curing the rubber in a state that the fiber is imparted with the chelating agent and is buried in the rubber, (i.e., natural rubber or a synthetic one) composition.
