A resinous cylinder comprises a cylindrical portion with an open end and a closed end, and is formed by flowing raw material of resin from the center of the closed end. A first attaching portion is disposed at the side of the open end of the cylindrical portion and has a hole for securing to a vehicle body. A flange portion has a second attaching portion disposed at the side of the closed end. The second attaching portion has a hole for securing the resinous cylinder to the vehicle body. A resin flowing portion is formed between the second attaching portion and the closed end of the cylindrical portion. A connecting portion connects the first attaching portion and the second attaching portion through a clearance with the cylindrical portion. A volume of the flange portion is reduced so that a resin flowing speed of the flange portion is faster than a resin flowing speed of the cylindrical portion. The first attaching portion, the flange portion and the connecting portion are integrally formed with the cylindrical portion.

A catalyst for the bisalkoxycarbonylation of olefins comprising a noble metal compound and a phosphine chalcogenide of the following formula (1): wherein each of R1, R2 and R3 is, independently, an alkyl group or an aryl group each of which may have a substituent, and A is a Group 16 element of the Periodic Table; and R1, R2 or R3 may be combined, directly or through a bridging group, with one another where the groups to be combined may be attached either to an identical phosphorus atom or to different phosphorus atoms. Element A includes oxygen, sulfur and selenium atoms. The noble metal compound includes palladium(II) halides and other palladium compounds. The catalyst may further include a copper(I) halide or other copper compound as a co-catalyst. The use of this catalyst can provide the bisalkoxycarbonylation of olefins with efficiency.

A combustible rocket is constructed with a laminate which comprises high tensile strength metal foils, easily combustible metal foils, and easily combustible adhesive layers. The rocket has sufficient mechanical strength and its shell can be gasified or disintegrated into finely divided pieces after the propellant of the rocket has burnt out at high altitudes. This rocket can be launched safely even in the vicinity of population centers without risk of injury to living things.

The invention provides inexpensively a pierce die by omitting a large pad at the time of executing a piercing process and pressing a work at only a minimum portion required for the piercing process, thereby reducing the portion to be machined as much as possible. There is provided a punch stripper comprising a pierce punch, a punch retainer holding the pierce punch, a cover which covers the pierce punch so as to protrude a leading end portion of the pierce punch, and is fastened by screws to the punch retainer, a stripper which is outward fitted to the pierce punch, presses the work before piercing the work by the pierce punch, takes out the pierce punch from the work after piercing, is received within the cover so as to move forward and backward, and forms a stop flange in a rear end, and a coil spring which is received within the cover so as to bring the stripper into contact with the stop flange, and energizes the stripper toward an outer side.
