Title: Image reader
Inventor: TANAKA NORIKO
IPC: H04N1/04
Filed: 1989-07-17
Abstract: PURPOSE:To prevent the local irregularities of an image by comprising the reader of a reading unit unifying an optical system such as a line image sensor, a rod lens array, and a light source, etc., and providing a white reference plate at one end of the unit. CONSTITUTION:The white reference plate 17 is provided at one end of the unit 16, and is moved in a subscan direction with the unit 16. An original 14 irradiated with the light source 12 arranged in the unit 16 and the image of the reference plate 17 are image-formed on the image sensor 11 with the rod lens array 13. Since the reference plate 17 is mounted on the unit 16, it is interlocked with the light source 12, the array 13, and the sensor 11, and the same part of the reference plate 17 can be read even on any line. Therefore, the reading level of the reference plate 17 referred when the signal level of one line of the original 14 is decided can be fed similarly on every line even when part of the reference plate 17 is stained, which prevents the reading of different white reference on each line from generating. Consequently, an original reading signal without generating the fluctuation of the signal level on every line can be obtained even when the light quantity of the light source is fluctuated.

Title: Image forming method
Inventor: OHASHI KUNIO
IPC: G03G5/082
Filed: 1987-07-25
Abstract: PURPOSE:To reduce stress toward a photosensitive body and to obtain sharp formed images by using a photosensitive body made of amorphous silicon, transferring electrostatic latent images thereon onto a dielectric sheet and sticking toner thereto. CONSTITUTION:Light for forming images is projected on the amorphous silicon photosensitive body 1 to considerably change electric resistance, and resistance value changing images are formed. After the photosensitive body a is electrified by an electrostatic charger 2 to form electrostatic latent images, they are transferred onto the dielectric sheet 3 and the toner is stuck to form developed images, which are transferred onto paper. For electrostatic latent images, their contract is sharp because undulations of the resistance of the resistance value changing images is clear, and said images do not become blurring even if they are transferred onto the dielectric sheet 3. Thus precise toner images can be formed, and no stress caused by toner is given to the photosensitive body 1, thereby preventing damages, distortion, etc.

Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To maintain reliability of control rod action even in the case when a gap between fuel assemblies is narrow by providing magnetic force connecting means (permanent magnets or the like) that can connect a ball nut and a piston. SOLUTION: In reactivity control at the normal time, ball screw mechanism 25 converts the torque of a driving motor 23 into the vertical motion of a ball nut 24, and a hollow piston 16 seated thereon with its own weight is vertically moved following the ball nut 24 so as to move a control rod in an insert or pull-out direction. In the case of a gap between fuel assemblies being narrow, friction is generated between the control rod and a channel box during pull-out motion, and there is the possibility of force acting to separate the piston 16 upward from the ball nut 24. In this case, connection between the ball nut 24 and piston 16 can be maintained by the magnetic force of permanent magnets 28, 29. At the time of scramming, high pressure water flows in through piping 26, and the piston 16 is separated from the ball nut 24 and rapidly pushed up to insert the control rod.

As a result, the analog output signal is the result of multiplication of a prescribed value in response to the control signal GA with the entered delta modulation code. Thus, the circuit is much simplified.
