Inventor: MORITA SHINJI
IPC: G02B26/12
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To write an image of high image quality without image deviation even by using a plurality of laser beams by setting the wavelength difference of the plurality of laser beams to a specific value or less when a plurality of liens are simultaneously scanned and exposed to write the image on the surface of a photosensitive member. SOLUTION: The wavelength difference of a plurality of laser beams is set to 12nm or less in an image forming apparatus. Specifically, two lasers emitted from laser units 21A, 21B are reflected by a polygon mirror 25, and scanned and exposed on a photosensitive drum 31 via an fθ lens 26, cylindrical lenses 24A, 24B and reflecting mirrors 29A to 29C. At this time, the beams are imaged in spot-like states aligned near a sub-scanning direction, and beam writing for simultaneously forming two scanning lines on the drum 31 is conducted. Thus, the image signals of every other scanning line are simultaneously input to laser units 21A, 21B, and the two scanning lines can be simultaneously formed.

Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To survey both horizontal and vertical planes by one machine by reflecting light at several times so as to change the optical path, before and after totally reflecting a light from a light source on a free liquid level. SOLUTION: When the whole measuring machine is inclined from the horizontal attitude at an angle θ1 , the free liquid level C1 of silicone oil C is inclined relative to a transparent vessel 2 at the angle θ1 . A laser parallel beam L1 is passed through an entrance wall part 2a and totally reflected at the liquid level C1 , and emitted from the vessel 2. The outgoing laser beam L2 is made into a laser beam of which the change θ3 of a reflecting angle is the same in all directions by a prism 5, reflected at a mirror, emitted in the vertical direction in the state of the change θ3 being set off by 6, and hence the angle θ1 is automatically corrected.  In the case of a vertical attitude similar to a horizontal attitude, the liquid level C1 is inclined at the angle θ1 relative to the vessel 2, the laser beam L1 is passed through the wall part 2a, reflected at a vertical wall part 2c and an upper wall part 2d, and totally reflected at the liquid level C1 . The angle θ1 is automatically corrected similarly to the horizontal attitude, and it is emitted in the horizontal direction. By projecting both correcting laser beams L3 so as to form horizontal and vertical planes, the surveying work of both planes can be executed.

Title: Dryness of steam measuring apparatus
Inventor: SENOO YASUTOSHI
IPC: G01N25/60
Filed: 1988-10-17
Abstract: PURPOSE:To achieve an easier operation and a wider measuring range by a method wherein a sampling tube is attached to a steam pipe and heating means are set at two positions, on upstream and downstream sides of the sampling tube to detect a steam temperature before and after the heating means. CONSTITUTION:A sampling tube 2 is connected to a steam pipe 1 for feeding a wet steam to take out a wet steam. The tube 2 is provided with heating means 3 and 4 at two positions, on the upstream and downstream sides thereof and the wet steam is heated by a power source 13. The wet steam before and after each of the heating means 3 and 4 and steam temperatures T1, T2 and T3 after heating are detected with temperature detectors 5-7 respectively. From the data thus detected, an arithmetic device 8 computes a formula x=1-(Cp/ r){(T3-T2)(H1/H2)-(T2-T-1)} (wherein Cp represents specific heat of steam, (r) latent heat at T1, H1 heating value of the heating means 3 and H2 heating value of the heating means 4) to calculate a dryness (x) of the wet steam. Since the H1/H2 is determined by resistances of the heating means 3 and 4 and is constant, the dryness (x) can be determined simply by measuring temperature differences T3-T2 and T2-T1.
