Abstract: PURPOSE:To perform individual and easy exchange of a flap by a method wherein a spherical protrusion is formed on either the rotary shaft of the flat or a joint to convert rotational movement of a gear into reciprocating movement, and a part engaged with the protrusion is formed in the other. CONSTITUTION:In exchange of only one of flaps 23, when two screws of a seal material 25 positioned facing the flap 23 are first removed and the seal material 25 is removed, a mounting tool 32 is exposed. Therefore, the knobs of support tools 31 on both sides are grasped to dislock a projection 35 from the mounting tool 32, and a support tool 31 is removed from the mounting tool 32. When a projection 56 is disengaged from an engaging part 59 of a rotary shaft 29 and rotary shafts 29 and 30 are removed from the flap 23, the flap 23 is easily removed from the mounting tool 32. By preceding a reverse work to the above, mounting of the flap 23 can be facilitated. Further, since the projection 56 of a joint 46 is formed in a spherical shape, wear between the engaging part 59 and the projection 56 and the generation of abnormal noise are suppressed, and resistance due to wear between the engaging part 58 and the projection 56 can be reduced.

Title: Electromagnetic flowmeter for flow in pipe is not fully filled
Inventor: SUZUKI ETSUMI
IPC: G01F1/58
Filed: 1991-03-25
Abstract: PURPOSE:To reduce a dead zone to approximately zero by providing a pair of electrodes on the protruding part of a top ridge which is extending at a right angle with the direction of the axis of a pipe and in the horizontal direction at the inner surface of the bottom part of a measuring pipe. CONSTITUTION:Under the state wherein an electromagnetic flowmeter for the flow in a pipe which is not filled fully is provided horizontally, a top ridge 13a is extending at a right angle with respect to the axial direction of the pipe in the horizontal direction. Both the upstream side and the downstream side of the top ridge 13a become slant surfaces 13b having the same slant angle including the top ridge 13a. A protruding part 13 having these parts is provided at the inner surface of the bottom part of a measuring device 11. A pair of electrodes 12 are arranged on the top ridge 13a of the protruding part 13 at a specified distance in the longitudinal direction. Since the protruding part 13 is present at the inner surface of the bottom part of the measuring chamber in this way, any minute flow rides over the protruding part 13 along the protruding part 13 and flows through. Therefore, the fluid is always in contact with the electrodes 12 arranged on the top ridge 13a, and the minute flow can be measured. Thus, the dead zone can be reduced into almost zero.

Title: Image forming method
Inventor: SAWAMURA TADAHIDE
IPC: G03G21/10
Filed: 1989-04-05
Abstract: PURPOSE:To prevent a large amount of toner from sticking only to a part of the surface of a latent image carrier by rotating the latent image carrier when a developer is removed and allowing a cleaning device to clean out toner sticking to the image carrier. CONSTITUTION:When a developer exists between the developing roll of a developing device 21B that has been used and a photosensitive body 18 when a coping mode is switched, the developing roll is rotated to carry out a developer removing action, that is, a napping action. At this time, not only the developing roll but the photosensitive body 18 is rotated, and the cleaning device 27 cleans the surface. Consequently, toner included in the developer never sticks only to a part of the photosensitive body 18 even if it sticks to the photosensitive body 18 together with the rotation of the developing roll.

Title: Shaving cutter grinding method
Inventor: NISHINO TAKAYUKI
IPC: B23F21/28
Filed: 1987-04-07
Abstract: PURPOSE:To enhance the machining accuracy of a work gear by previously setting a plurality of tooth grinding data in accordance with the tooth surface condition within the range in which the cutter can be used, and by modifying the tooth grinding data on the basis of the tooth surface measured value after trial cut and error from the target value.

At the time of re-grinding of the tooth surface of shaving cutter, the tooth grinding data according to the current tooth surface shape measured by a three-dimensional measuring instrument 3 is read, and thereupon re-grinding is carried out. Machining of the work gear with this re-ground cutter gives the work gear an approximate optimum shape regardless of the current tooth surface condition of the cutter. As the cutter grinding data to be set previously is stored upon necessary modification on the basis of the work gear tooth surface measured value and the error from target value, the precision of each grinding data will become higher.

Abstract: PROBLEM TO BE SOLVED: To prevent the full-open diameter of a diaphragm from varying in a focus section by providing a cam mechanism with an invariable section wherein a restriction member is not displaced as the restriction member and an engagement member move relatively. SOLUTION: On a shutter unit (stop mechanism part) 8, the restriction member 41 projects which restricts the full-open position of a shutter blade (stop) 40. The engagement member 4b engages the restriction member 41 by the relative movement of a 2nd moving frame 4 to a 1st moving frame 3. The engagement member 4b has a stepped cam, which has a slanting part and a flat part (invariable section). The projection part of the restriction member 41 engages the cam of the engagement member 4b and rotates the restriction member 41 through the slanting part to increase the full-open diameter of the stop. When 1st and 2nd lens groups L1 and L2 move in the focus section, the projection part does not rotate since it move on the flat part, so that the full-open diameter of the diaphragm will not rotate during focusing operation.
