IPC: H04N5/355
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To provide a solid-state image pickup element which can display sufficient detecting capability when the light/dark difference of image light from an observation object is large. SOLUTION: A cover layer 14 arranged between an opening part 5 where many small holes 6 for decomposing image light of the observed object into fine pixels are formed and a photoelectric conversion part 3 where many pixels passed through the small holes 6 are imaged and the light and shade of the light of the pixels are converted into the intensity of electricity is formed of a light transmissivity adjustment member constituted by mixing a dimming substance formed of silver halide with a transparent substance made of quartz, and given characteristics of variation in light transmissivity with the quantity of light.  Consequently, the incident light intensity can be set equal to imaged light intensity in the dark area of the image light (low intensity area) and the imaged light intensity can be set lower than the incident light intensity in the light area (high intensity area), so that even when the image light from the observed object has a large light/dark difference, the solid-state image pickup element 11 can display sufficient detecting capability.

Title: Magnetic recording/reproducing device
Inventor: WAKATSUKI SHIGETO
IPC: G11B15/61
Filed: 1994-01-17
Abstract: PURPOSE:To stable perform recoring/reproducing without giving damages to a tape even when tape tension is low by inclining an input side guide post. CONSTITUTION:When an average pulling stress in a tape width direction is Tm and a pulling stress on a magnetic tape abutting position is TL, the stress distribution of a tape width direction at a drum 1 entrance is set atTL/Tm >=1.2. Specifically, an entrance side guide post 7 is set inclined in a direction along the center direction of a tape winding angle so that no problem is generated even when a tape is travelled over 20 minutes. Thus, the travelling route of a tape lower end is slightly longer than that of the upper end, a pulling stress on the tape lower end is bigger as indicated by a vector 12 in the drawing and the stress distribution of the tape width direction on the drum entrance is set as described above. Therefore, changes in the thickness of an air film are made small from the drum entrance to the exit and a stable abutting between the magnetic head 3 and a tape 6 is obtained.

Abstract: PURPOSE:To miniaturize a device and to reduce its cost, by storing a cleaner blade in a developing device, and doubling a charger as a transfer means in a 2-rotation and 1-copy type electrophotographic copier. CONSTITUTION:A photosensitive body 1 is charged uniformly by a charger 2, an image of an original (b) is exposed, is developed by a developing roll 52, and a toner image is formed on the photosensitive drum 1.

The remained charge is eliminated by irradiating the photosensitive drum 1 by a destaticizing lamp 12, and the remained toner is removed by a cleaner blade 4 to collect it into a developing device 5. Since the photosensitive surface is filmed with a stearic acid zinc film, even if the cleaner blade 4 is kept at contacting, an electrostatic image to be formed by the first rotation of the photosensitive drum 1 is not disordered.

Abstract: PURPOSE: To make possible the side end registering of an original on the original platen surface by so constituting the devide that the lens is moved not only in its optical axis direction but also in its perpendicular direction at the variable power.  
     CONSTITUTION: A rail 23 is extending in a direction inclining at a certain angle to the optical axis of a lens 4 within a horizontal plane. Hence, if a supporting base 22 is moved on the rail 23 for the purpose of variable power, the lens 4 parallel moves in the optical axis direction and in the direction perpendicular to the same while maintaining the direction of its optical axis. If the movement extent Δl in the direction perpendicualr to the optical axis of the lens 4 is so selected as to satisfy the formula I (where L is the distance between the optical axis position of the original and the end part, α 1  is the magnification before variable power and α 2  is the magnification after variable power), the inner side end of the image on the exposure plane at an exposure part 5 does not move before and after the variable power by the movement of the lens 4. If the relation of the forward side index of the original and the lens are beforehand so set that this inner side end which does not move aligns to the inner side end of the advancing region of photosensitive paper, the side end registering of the original C on the original platen surface 1 may be performed.

IPC: B65G53/52
Filed: 1984-01-12
Abstract: PURPOSE:To prevent pressure loss and clogging in a rectifier device in a fluid conveyor system, by providing such an arrangement that fluid introduced through an inlet pipe is led into a body having an invertedly conical bottom through a rotatable guide section, and thereafter is led into an outlet pipe. CONSTITUTION:A guide member 8 is rotated by manipulating a lever 10 to adjust the angle theta of a through-hole 8c with respect to the Z-Z axis. Thereby, the through-hole 8a is directed toward a lid 6 and as well is positioned in a plane defined by the axes X-X and Y-Y, thereby the fluid will not swirl in a body 4. However, if the through-hole 8a is positioned so as to cross the above-mentioned plane, the fluid will siwrl in the body 4. Accordingly, biphase fluid of solid and gas led into the body 4 through an inlet pipe 1 is subjected to enlargement with the body 4, and is directed in accordance with the pattern of the fluid, thereby it is possible to aim at uniformalizing the distribution of concentration of solid in the cross-sectioned area of an outlet pipe 7. Thereby pressure loss and clogging are prevented to facilitate the maintenance thereof.

Abstract: PURPOSE:To realize the D/A converter with accuracy of 18-bit without increasing sampling frequency by forming the D/A converter in which a ternary input data is not subjected to the effect of the components similarly to the case with a binary data input. CONSTITUTION:A signal converted into a ternary signal is inputted to a D/A converter, in which the signal is in operation with respect to two positions. Switches S1, S3, S4 are connected to ground in a 1st phase. Then the switch S2 is connected to a VREF when an output of a modulator is logical 1 and connected to ground when the output of the modulator is 0 or-1. Then in a 2nd phase, the switches S1, S2 are thrown to the position of the input of an operational amplifier and the switch S3 is thrown to the position of the output. The switch S2 is connected to ground when the output of the modulator is 1 or 0 and connected to the VREF when the output of the modulator is 1 or 0 and state of the switch S2 should not be changed when the input is 0. As a result, the D/A converter for a ternary input having an excellent linearity independently of the component accuracy is realized with an area not different from that of the D/A converter for a binary input.
