Abstract: A device includes: a complementary transistor including: a first transistor having a first source/drain region and a second source/drain region; and a second transistor stacked on the first transistor, and having a third source/drain region and a fourth source/drain region, the third source/drain region overlapping the first source/drain region, the fourth source/drain region overlapping the second source/drain region. The device further includes: a first source/drain contact electrically coupled to the third source/drain region; a second source/drain contact electrically coupled to the second source/drain region; a gate isolation structure adjacent the first and second transistors; and an interconnect structure electrically coupled to the first source/drain contact and the second source/drain contact.

Abstract: A pitching practice apparatus includes a frame unit having a rectangular frame member, X-axis and Y-axis sensor units mounted on the frame member, a control unit connected to the sensor units and to a sound generating device, and a net body provided on the frame unit. The sensor units are operable so as to form sampling regions for sensing entry of a ball into the frame member. The control unit determines position of the ball entering into the frame member, and compares the ball position with preset parameters to determine whether the ball is a good ball or a foul ball. Ball information determined by the control unit is shown on a display device. The sound generating device is used to generate a sound output corresponding to status of the ball that was thrown into the frame member as determined by the control unit.

Abstract: A device includes a base secured in a car, a stopping block displaceable on the base, an actuating member for displacing the stopping block with, and a lock block secured around a steel rope of a control of a hood of the car, which control can be used to pull the steel rope for making the hood become openable; the stopping block has a big hole, and an horizontal slot communicating with the big hole and as high as center of the hole; the rope is passed through the stopping block with the lock block arranged behind the stopping block; the lock block can't pass through the slot; the stopping block is displaceable to such position as to exactly face the lock block at the slot, preventing the rope from being displaced; thus, thieves can't open the hood to cut off the power to the alarm for stopping sounding of the alarm.
