    摘要： In an apparatus for profile grinding a closed curved surface such as a trochoidal curved surface of the type wherein the attitude of a worktable which supports a workpiece is profile controlled in accordance with a master profile corresponding to the closed curved surface to be formed in the workpiece, the axis of a grinding wheel is maintained at a fixed position, a mechanical information is generated by the cooperation of a master cam having a peripheral profile corresponding to the profile of the closed curved surface and a master cam normally urged against the peripheral profile, and the attitude of the worktable is controlled in accordance with the mechanical information. Where a grinding wheel having a diameter different from a predetermined value is used, a primary feed calculated by an equation to be described later is applied to the grinding wheel thus enabling to use a grinding wheel of any diameter.

    摘要： A double-sided heat-sensitive adhesive sheet comprises a support provided with a release layer on one side thereof and heat-sensitive adhesive layers which are formed on both sides of the support and have sufficient adhesion to the support but can be easily peeled apart from the release layer, wherein the release layer and the heat-sensitive adhesive layer has at their interface a 180° peeling resistance of 10-30 g/50 mm in a peel test performed at a peeling speed of 500 mm/min. in an atmosphere of 20° C. and 65% RH. The adhesive sheet is interposed between each opposed pair of information-recorded faces of recording material having on one side at least two spaces for information-recording, and heat is applied to the resultant assembly to make a laminate. The laminate can have a size and weight suitable for mailing as a postcard, and can bear confidential information on the inside and be peeled apart when desired.

    摘要： A main-shaft malfunction-state detector in an air bearing type machine tool, in which an abnormal contact of a main shaft with a housing is reliably and automatically detected. The contacting state of the main shaft 11 and the housing 13 is detected through the presence of electric conductivity by a contact detection device 31. A contact decision device 32 determines the contact of the main shaft 11 with the housing 13 based on the detected conductivity, thus automatic and certain preventative measures, such as the main shaft of the machine tool stops and so on, are based on the above decision.
