Abstract: PURPOSE:To easily correct deviation in focus position between plural light beams and to eliminate variation in the distance between the light beams at right angles to a scanning direction as to a device which writes an image with plural laser beams by using plural laser diodes and one cylinder mirror. CONSTITUTION:A light emitting device 2 which outputs the laser beams is provided with two laser diodes 3 and 4 and outputs the two laser beams, which are passed through an optical system device to generate two parallel light beams Ra and Rb, thereby scanning a photosensitive body 13. An optical system consists of a collimator lens 5, cylinder lens 7, polygon mirror 10, f-theta lens 11, and cylinder mirror lens 12 and has a field lens 15 arranged between the lens 7 and mirror 10. Then the image-side focus of the collimator lens 5 and the cylinder mirror 12 are put in conjugate relation through the field mirror 15 and even if the two light beams deviate from the center of the optical axis of the scanner, the two luminous flux can be corrected so as to meet each other on the cylinder mirror 12.

Title: Grain storage cabinet
Inventor: YAMAMOTO KOJI
IPC: B65D88/66
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a grain storage cabinet with which grains can be smoothly discharged without being stuck on an inner wall surface and the grains can be prevented from being stuck on the inner wall surface by being dragged with the conveyance power of carrier conveyer under a discharge part. SOLUTION: When vibrators 18A and 18B are vibrated after a discharge part 12 is opened, grains (a) stuck on the inner wall surface around funnel- shaped storage part 11 are shaken down to the discharge part 12. Since the funnel-shaped storage part 11 is made of stainless so as to easily slip, the grains (a) are hardly stuck because of that material as well and further hardly damaged by the vibrations of vibrators 18A and 18B as well. Since the grains (a) reaching the discharge part 12 are dried by the heat of heater 19, they are passed through the discharge part 12 and discharged from a grain storage cabinet 10 easily. Thus, even considerably humid grains can be smoothly discharged without clogging at the discharge part.

Title: Electromagnetic coupling type coordinate reading device

IPC: G06F3/0488
Filed: 1983-04-22
Abstract: PURPOSE:To enable use of optional material for a sense line plate by providing an exciting coil for correcting coordinate value in a tablet. CONSTITUTION:The moment a coordinate indicator 7 leaves the face of a tablet plate and goes out to outside of range of reading, a controlling signal C is outputted from a CPU9 and a switching circuit section 10 is switched so that a correcting coil 5 is excited, and coordinate value generated thereby is determined. A correction coefficient is obtained from this value and coordinate value of the coil 5 measured beforehand under a specified condition, and stored in a memory in the CPU9. When the indicator 7 gets near the tablet face and enters inside of the range of reading to generate coordinate value, the coordinate value is corrected using above-mentioned correction coefficient, and then ordinary coordinate processing is performed. Thus, optional material can be used for the sense line plate, and cost can be reduced by simple software processing without lowering accuracy of coordinate reading.

Title: Stacking vibration removing apparatus of scanning type tunnel microscope
Inventor: OKANO MAKOTO
IPC: H01J37/16
Filed: 1987-03-27
Abstract: PURPOSE:To enhance a vibration removing rate, by constituting each of the spring devices arranged between each of the stages of vibration removing stands by symmetrically arranging inclined leaf springs made of rubber. CONSTITUTION:Each of the spring devices interposed between each of stages is constituted by symmetrically arranging inclined leaf springs 26 made of rubber in the polygonal shape as shown by a drawing and the spring device on the side of the lower stage has load resistance larger than that of the spring device on the side of the upper stage and the intersecting points of the spring axes of the leaf springs are positioned above the center of the gravity of each spring device. By this constitution, for example, the leaf springs 26 between vibration removing stands 22, 21 receive load by bending deformation and the spring constant to the bending load becomes small in inverse proportion to the cube of the substantial length of each leaf spring 26. Further, the load component of each spring in the lateral direction is set off by the symmetric arrangement structure and the rigidity thereof in the lateral direction becomes large. Therefore, even when the spring constant in an up-and-down direction is reduced to enhance a vibration removing rate, each spring constant in lateral and peripheral directions can be made the same to that in the up-and-down direction and the shift movement or revolution of each vibration removing stand in the lateral direction is prevented to make it possible to enhance the vibration removing rate.

Abstract: PURPOSE:To obtain an optical inclination sensor which detects the angle of inclination of an objective surface accurately even when varying in distance to the objective surface slightly, by using a cylindrical lens for an optical system. CONSTITUTION:Light is projected along an optical axis S1 and when an objective surface F1 is at right angles to the optical axis S1, its reflected light has the same intensity of optical axes S4 and S5, and is forcused in a vertical line with the same brightness through a cylindrical lens 101 and a reflecting mirror 102a.
