摘要： Capsule-shaped polymer particles and a process for the production thereof are described. In one embodiment of the process, a polymerizable monomer component containing a cross-linkable monomer and a hydrophilic monomer, and an oily substance are finely dispersed in water to prepare an oil-in-water emulsion and then the polymerizable monomer component is polymerized, whereupon capsule-shaped polymer particles containing the oily substance as a core material are obtained. Upon removal of the oily substance in the particles, there are obtained capsule-shaped hollow polymer particles. These capsule-shaped polymer particle are excellent in such properties as mechanical strength and heat resistance, and thus can find many applications.

摘要： A method for cleaning structural surface 1 by forming a substratum membrane 17a thereon through application and drying of a thin layer 16 of aqueous solution 5 of membrane-forming polymer 2 on a structural surface, spreading a fibrous reinforcing member 15 on the thin layer 16 before drying or the substratum membrane 17a after dried, and applying the aqueous solution 5 on the outer surface of the reinforcing member 15 while wetting it in such a manner that, upon drying, an overlying membrane 17b integral with both the substratum membrane 17a and the reinforcing member 15 is formed so as to generate a multi-layer membrane 18 having the substratum and overlying membranes sandwiching the reinforcing member. After causing foreign matters on the structural surface 1 to adhere onto the substratum membrane 17a, the multi-layer membrane 18 is peeled off from the structural surface 1.

摘要： An apparatus for detecting lateral deviations of a bandsaw blade has a follower which is in contact with and follows lateral movement of the blade. A sensing circuit, which is connected to the follower, generates deviation signals representing movement of the follower. A control circuit which is responsive to the deviation signals stops the bandsaw when the lateral movement of the blade has deviated beyond established limits.

摘要： A method and apparatus for recording an operating status of an NC processing machine is provided. Measuring and recording operations can be performed with trial processing and actual processing distinguishing from each other. In order to record the operating status in a case where an NC apparatus is controlled to cause an NC processing machine i.e. a press brake, to perform continuous processing according to a processing program, a processing condition for a work used in previous processing is stored in a memory. A comparison/decision unit decides whether a processing condition for a work used in current processing coincides with the stored processing condition of the work in the previous processing. If the current processing condition coincides with the previous processing condition, a recording unit records the current processing as actual processing. On the other hand, if the current processing condition does not coincide with the previous processing condition, the recording unit records the current processing as trial processing.

摘要： In a bender (e.g., press brake), work (plate material) can be bent by a bending tool composed of a pair of punch and die. A position detector (17) mounted on a movable side of the bending tool generates a limit point pulse (ULi) whenever the tool reaches a limit point. A timer (29) measures a time interval between the two limit point pulses (ULi). A time compare discriminate section (31) compares the time interval measured by the timer with a reference time interval (TR), and further discriminates the current bending as a trial bending when the time interval is longer than the reference time but as an actual bending when shorter than the reference time. Further, an arithmetic section 33 calculates a sum total number of times of the bending and the sum total time period spent in the bendings, separately in both of the trial and actual bendings. The obtained bending data are displayed or recorded to obtain an accurate man-hour in the bending processing.
