Abstract: PURPOSE:To prevent the deut of a pressure pin from remaining on a work when it is not punched by moving a pressing member vertically with a cam mechanism in selecting the case when press working round the work and punching inside the work are performed at the same time or the case when only press working round the work is performed. CONSTITUTION:In press working which required punching inside the work, the die heights of an upper die 22 and a lower die 20 are adjusted at a position capable of working a hole by a punch 24. When a holding plate 28 is set by a driving means 24 to a falling position through a cam mechanism, since a pressing member 26 presses the working on a worked hole when the punch enters the falling hole, scraps are removed. When the circumferential part of the work performs press forming only, the die height is adjusted so that the punch does not come in contact with the work and when the holding plate 28 is located to the rising position, through the punch is lowered by press working, the deut of the pressure member does not remain on the work because the pressure member 26 is separated from the work. Dislocation is not generated between the punch and the working hole of the lower die.

Title: Secondary screen inserting device of television receiver
Inventor: TANAKA TAKEO
IPC: H04N5/45
Filed: 1984-05-09
Abstract: PURPOSE:To simplify the structure of the titled inserting device together with reduction of the cost by reading out a recording medium storing the information on a secondary screen at a speed N times as high as a normal case. CONSTITUTION:The TV signal received by an antenna 11 is sent to an adder circuit 23 as well as to a synchronizing circuit 13 to undergo the synchronizing separation. Thus the 1st horizontal and vertical synchronizing signals are obtained. These signals are used as the timing signals to obtain the 2nd video signal for secondary screen and also as the control signals for insertion of screen. When signals are read out of a magnetic disk 14, the rotational frequency is kept to three times that of a recording mode owing to the servo control applied based on the 1st synchronizing signal. Thus the video signal for secondary screen which is picked up by a magnetic head 17 is used as the 2nd video signal with 1/3 reduction. Therefore, various types of still pictures can be inserted as the secondary screen by synthesizing main screen signals.
