Abstract: PROBLEM TO BE SOLVED: To release a door lock without using a key by using an on-board camera for taking a photograph of outdoor views to take a picture of a personal physical feature in common, and releasing a door lock when a physical feature registered in advance coincides with the physical feature taken by the camera. SOLUTION: A CCD camera 12 for taking a picture of the rear side, installed in a door mirror photographs other vehicles in the rear side through a lens 11 provided for remote photographing at a running time of a vehicle. When a vehicle approaches, the camera acts as a part of a rear side alarm system issuing an alarm to a driver who intends to change his lane. The lens 11 can be changed over to neighboring photographing or remoto photographing and it is set in the neighboring photographing for taking a fingerprint. When the image of fingerprint of a finger 1 is taken by the camera 12 as a driver gets in the vehicle, a comparator portion 14 compares the fingerprint with a fingerprint registered in advance in a fingerprint register portion 13. When both fingerprints coinside with each other, a control portion 15 releases the lock 18 of the door by a lock driver 17.

Filed: 1994-05-30
Abstract: PURPOSE:To reduce irregularity in forming conditions, and restrict irregularity of brightness at the time of driving image display in a forming process to form an electron emission part by energization processing to plural thin films. CONSTITUTION:A specific resistance 202 is connected serially to each electron emission element (surface conduction type electron emission element, that is SCE element 201) for composing a multiple cold cathode electron source.

Title: Front and back reversing mechanism of sheet and the like
Inventor: IMURA KOJI
IPC: B65H29/58
Filed: 1986-05-23
Abstract: PURPOSE:To reverse the front and back of even an unstiff sheet by holding a sheet out of a feed port between rollers, in between one drum and a number of small diameter idler rollers provided around said drum, and reversing said drum when front and back is detected by a sheet sensor. CONSTITUTION:When a sheet 15 is reversed, first, the sheet 15 is carried in with a drum 1 being rotated counterclockwise and passes through sheet detecting sensors 9, 10, causing a detected signal 10' to be L. When the drum 1 is further rotated counterclockwise and as the rear end of the sheet 15 passed through the sensors 9, 10, the detected signal 10' becomes H, and the output signal 24' of a one shot multivibrator 24 becomes H. At this time, since a reversing command 30 is H, the sheet 15 is completely carried into a reversing part 95 after a defined time elapsed from the time when the sheet 15 completely passed through the sensors 9, 10. Here, a binary counter 28 changes the signal 28' from L to H and an AMP 29 reverses a motor 16, rotating the sheet 15 for one rotation clockwise to reverse the front and back of the sheet 15.
