Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a die and to reduce the deformation of a blade by caulking with using a caulking projection formed on both sides of a circular arc part of a caulking projection part installed on a caulking member. SOLUTION: In a caulking member 1 having plural numbers of caulking projections 2, holes 3a, 4a of a pair of plate members 3, 4 are fitted in the caulking projection 2. A circular-arc part 20 is formed on almost central part on the caulking projection 2, and a pair of protrusive caulking projections 21 are formed on the both sides of the circular-arc part 21. By collapsing the caulking projection 21 with using a jig from the upper side of the circular-arc part 20, the caulking projection 21 is deformed and engaged to the plate members 3, 4 and joined firmly. Because a circular-arc part 20 is formed inside the caulking projection 21, it is punched easily from a hoop metal with a die. Further, caulking can be executed also even with a weak force in the time of caulking.

Abstract: PURPOSE:To use only one reception block system and to reduce the cost by providing a controller or the like storing plural broadcast frequency data included in an RDS(radio data system) signal. CONSTITUTION:In the case of receiving a radio wave of an RDS system broadcast station with a reception block 100, an RDS signal is inputted to a controller 13 via an RDS signal demodulator g and plural broadcast frequency data in the AF signal is stored in a memory. Simultaneously, an S meter output SD outputted from a detector 4 is detected and when the level is smaller than a reference value, a signal MUTE is outputted to a mute circuit 6 and a voice output is interrupted. Then a broadcast frequency data FD different from that during reception at present is outputted sequentially to a PLL circuit 10 among the plural broadcast frequency data stored in advance. When a level of the output SD is larger than the reference value, the data is outputted to the circuit 10 to stop the output of the signal MUTE. Thus, one system of the reception block is enough and the cost is reduced.
