A method for manufacturing a hollow protruding implement (1) including a fine hollow protrusion (3) having an opening (3h) of the present invention includes a protrusion forming step of inserting a projecting mold part (11) into a base material sheet (2A) from one face (2D) side thereof, the base material sheet containing a thermoplastic resin, thereby forming a non-penetrated hollow protrusion (3) projecting from another face (2U) side of the base material sheet (2A). Subsequently, an opening forming step is performed in which an opening (3h) that penetrates the hollow protrusion (3) is formed by using a contactless opening forming means disposed on the other face (2U) side of the base material sheet (2A).

A cutting device of cutting a soft honeycomb mold body in a cutting direction perpendicular to an axial direction of the honeycomb mold body. A cutting device has a wire, a tension supply part and a pair of ultrasonic generators. The wire has a contact part which is stretched and in contact with the honeycomb mold body when the honeycomb mold body is cut. The tension supply part supplies tensile to the contact part when the honeycomb mold body is cut. The pair of ultrasonic generators have respective vibrator terminals arranged in contact with the contact part of the wire. The ultrasonic generators generate ultrasonic vibration in the cutting direction and supply the generated ultrasonic vibration directly to the wire.

The present invention concerns a method of detecting the making or breaking of contact of a sonotrode (4) which is caused to vibrate with a frequency f and a vibration amplitude A.sub.0 with a counterpart element (5). To provide a method with which contact-making or breaking of a sonotrode with a counterpart element can be particularly quickly and inexpensively detected it is proposed according to the invention that the method has the following steps: a) recording a time configuration of the vibration amplitude A.sub.0 (1) during a first measurement time interval ΔT, and b) determining from the time configuration of the vibration amplitude A.sub.0 (1) whether making or breaking of contact occurred within the measurement time interval ΔT.
