     CONSTITUTION: By lowering the pressure of an air spring 18, for instance, inside and outside panels Wb, Wa of an automobile door are overlapped and set in a lower die 2. When a cylinder 28 is extended, the power doubling means causes a preliminary curling; blade 19 to push a flange part F, thereby preliminarily curling, about 45° inside. Then, a motor 11 is rotated in the normal direction to turn a nut 6, and a push rod 8 and a pressurizing base 9 fixed thereto are lowered from the position shown by chain line. At this time, a guide rod 14 and a base 15 are also lowered, and when a final curling blade 17 abuts against the flange part F, the spring 18 is compressed, so that a gap is created between a collar 14a and a boss 9a. This is detected by a sensor, and the motor 11 is stopped, and high pressure air is sent to the spring 18 at the same time. As a result, the base 15 is pressed down hard, and the blade 17 folds the flange part F completely.

Title: Paper position detector for duplicator
Inventor: SASAKI YUTAKA
IPC: B65H7/06
Filed: 1980-06-27
Abstract: PURPOSE: To increase detecting accuracy regardless of rigidity of paper and improve capability of assembling and maintaining the apparatus in such a way that a detecting hole is provided on the passage of paper, it is communicated to a pneumatic detecting means so as to detect pressure changes due to the transit of paper.  
     CONSTITUTION: Though when paper 2 does not come to a detecting hole 1, the total opening area of the detecting hole 1 is opened to the pressure in a negative pressure passage 3, when the paper 2 interrupts the detecting hole 1, the opening area is decreased, and negative pressure in the negative pressure passage 3 and in the detecting passage 5 is increased. In consequence, a diaphragm 6 helps an actuator 7 strongly push an operation point 8a, a microswitch 8 is turnes on, and the timing is taken out as electric signals so as to detect the position of the paper 2. Thus, paper detection can be done in high accuracy independently of the paper rigidity, and capability of assembling and maintaining can be improved.

Title: Cathode-ray tube device
Inventor: NATSUHARA MASAO
IPC: H01J29/48
Filed: 1982-05-21
Abstract: PURPOSE:To obtain good resolution over all regions on a phosphor screen by correcting the shaping distortion of a beam spot caused by an electron beam that receives deflection in a ununiform deflection magnetic field. CONSTITUTION:When an electron beam 25 with a long-sideways elliptical cross section is incident on a main lens section 24, the focusing that is strong in the horizontal direction and weak in the vertical direction is actuated due to the spherical aberration of the lens and a focal point 26 in the vertical direction is faster than a focal point 27 in the horizontal direction. Like this, when the cross-sectional shape of the electron beam passing through an acceleration electrode system 12 is deflected in an elliptical form that is long in the horizontal direction following an increase of beam deflection, the focusing of the main lens section 24 on the electron beam is stronger in the horizontal direction than in the vertical direction. This event takes place so that the electron beam in the deflection magnetic field can be offset to intensely be focussed weakly in the horizontal direction and strongly in the vertical direction as the beam deflection increases.
