摘要： PROBLEM TO BE SOLVED: To perform press working continuously to other press processes without being restrained in the number of processes or the arrangement of the processes by making forming weighting roughly the same value to other processes, in minimally forming the radius shape part in the inner periphery and the flange of a thick sheet and small diameter press formed article.
SOLUTION: The end face forming process is performed dividedly in two times or more. In the first process, a wedge is formed on the inner periphery in the flange of a workpiece. In the second process, the wedge is formed by the same punch to the final product shape, with the material of the wedge flowed to the radius shape part formed in the inner periphery and the flange of the workpiece, and with the radius shape part reduced. Consequently, the method enables an highly accurate end face to be obtained, also enabling the radius shape part to be minimized that is formed in the inner periphery and the flange of even a thick sheet.

摘要： PROBLEM TO BE SOLVED: To provide a filter cover having only a small degree of electromagnetic effect to a dielectric resonator and capable of elongating the life of a press die long without a loss of isolation between transmission and reception.
SOLUTION: The dielectric resonator, a high-frequency transmitter connected to the dielectric resonator, a base to which the dielectric resonator and the high-frequency transmitter are to be mounted, and a base are jointed together. A cover covers the dielectric resonator and the high-frequency transmitter. The distance between the surface of the cover in the direction of the presence of the dielectric resonator and the surface of the base in the direction of the presence of the dielectric resonator is the 1/2 effective wavelength of the frequency of the oscillator or shorter. The cover comprises periodic recesses and protrusions of the 1/4 effective wavelength of the frequency of the oscillator in the direction of the presence of the dielectric resonator to form a VCO (Voltage-Controlled Oscillator). In the VCO, the most proximate distance between at least the surface of the dielectric resonator in the direction of the presence of the cover and the surface of the cover in the direction of the presence of the dielectric resonator is the 1/4 effective wavelength of the frequency of the oscillator or longer.
